FIG. 1 is a photograph of an upper surface of a cuttable knitted fabric according to one embodiment of the present disclosure.FIG. 2 is a photograph of a lower surface of the knitted fabric ofFIG. 1 .FIG. 3 is a vertical cross-sectional view of the cuttable knitted fabric according to one embodiment of the present disclosure.FIG. 4 is a photograph of an end of the knitted fabric ofFIG. 1 cut along an “A” line. - Referring to
FIGS. 1 to 4 , a cuttable knittedfabric 100 according to one embodiment of the present disclosure may include a knittedweb 110 and a reinforcingportion 120. - The cuttable knitted
fabric 100 may be formed of a fabric that can be cut by coupling an upper surface or a lower surface of the knittedweb 110 and the reinforcingportion 120 inside the knittedweb 110. In the cuttable knittedfabric 100, the reinforcingportion 120 is generally coupled to the knittedweb 110 having a substantially plate shape, and thus, strength of the knittedfabric 100 can be higher than that of the knittedweb 110. -
FIG. 5 is a photograph illustrating that curl-up occurs in a general knitted fabric. - Referring to
FIG. 5 , a general knitted fabric has a problem in that a curl-up phenomenon occurs in which an edge portion is curled due to unique characteristics of the knitted web. In addition, in the case of the general knitted fabric having a yarn break in any one portion, the knitted web may be unraveled as the yarn is unraveled. For this reason, a general knitted fabric cannot be cut, unlike a textile, and there is a limitation in producing products of various designs. - As illustrated in
FIGS. 3 and 4 , in the cuttable knittedfabric 100 of the present disclosure, the reinforcingportion 120 supports the knittedweb 110 as a whole to prevent curl-up from occurring. In addition, since the cuttable knittedfabric 100 is fixed to the knittedweb 110 while the reinforcingportion 120 is coupled to the knittedweb 110, the yarn is not unraveled even when the yarn of the knittedweb 110 is cut during the cutting process. In addition, since the cuttable knittedfabric 100 has the knittedweb 110 as a basic skeleton and reinforcing fibers are coupled, the knittedfabric 100 has good elasticity and flexibility and does not wrinkle. In addition, the cuttable knittedfabric 100 may have good heat retention and breathability, and may have waterproof properties. - The knitted
web 110 may be formed by woven in a substantially plate shape by a single yarn. The yarn may be formed to include mohair, cotton yarn, or nylon. In addition, the yarn may be formed by mixing at least two types of mohair, cotton, and nylon. The knittedweb 110 may be formed to include a through hole in which the yarns are spaced apart from each other and formed between the yarns. The knittedweb 110 may be formed of yarns of various thicknesses or diameters. The knittedweb 110 may be formed in a polygonal plate shape, such as a disk shape, a square plate shape, or a hexagonal plate shape. The knittedweb 110 may be formed of a general knitted fabric. - Meanwhile, the cuttable knitted
fabric 100 may include a plurality of knittedfabrics 110 woven by a single yarn. In this case, the knittedweb 110 may be arranged so that side surfaces of the knitted web are in contact with each other or are spaced apart from each other in the knittedfabric 100. In this case, the plurality of knittedfabrics 110 may be fixed while being coupled to one reinforcingportion 120. - The reinforcing
portion 120 may include an upper reinforcinglayer 121, a lower reinforcinglayer 122, an inner reinforcinglayer 123, and anedge layer 124. The reinforcingportion 120 may be coupled to theknitted web 110 in the entire region of the knittedweb 110. The upper reinforcinglayer 121, the lower reinforcinglayer 122, the lower reinforcinglayer 122, and theedge layer 124 are coupled to each other. The upper reinforcinglayer 121, the lower reinforcinglayer 122, the lower reinforcinglayer 122, and theedge layer 124 may be integrally formed. The upper reinforcinglayer 121 and the lower reinforcinglayer 122 may be formed to have the same thickness or different thicknesses. - The reinforcing
portion 120 may be formed while reinforcing fibers positioned above and below the knittedweb 110 are coupled to theknitted web 110. The reinforcing fiber may be a material having its own entanglement, such as fine fibers thinner than a yarn, a thread, or a fiber. - As an example, the reinforcing fiber may be formed of wool (woolen material, lamb's wool, merino wool, pima wool), cotton wool, or nylon cotton. The reinforcing fibers may be formed by mixing two or more materials selected from wool (woolen material, lamb's wool, merino wool, pima wool), cotton wool, and nylon cotton.
- The reinforcing fibers of the reinforcing
portion 120 have a property of being tangled with each other, and may be introduced into the yarn of the knittedweb 110 and coupled to the yarn while being tangled. The reinforcing fibers of the reinforcingportion 120 may be coupled to the yarns of the knittedweb 110 through a needling process. The reinforcing fibers of the reinforcingportion 120 may fix the yarn of the tissue of the knittedweb 110 while filling the inside or the tissue of the knittedweb 110. Since the reinforcing fiber is thinner than the yarn, the reinforcing fiber may be easily introduced into the yarn. The reinforcing fibers may be formed into theknitted fabric 100 that can be cut by changing the physical properties of the knittedweb 110 while being coupled to theknitted web 110. - The reinforcing fibers of the reinforcing
portion 120 may prevent theknitted web 110 from being unraveled when theknitted web 110 is cut. The reinforcingportion 120 may reduce the loosening property of the knittedweb 110. In addition, while the reinforcing fibers of the reinforcingportion 120 are coupled to theknitted web 110, the cuttable knittedfabric 100 may maintain a constant shape. That is, the reinforcing fibers may be maintained in a layer shape on the upper and lower surfaces of the knittedweb 110 while being coupled to the yarn of the knittedweb 110. - Meanwhile, the reinforcing
portion 120 may be formed by mixing reinforcing fibers with an adhesive such as glue and needling the reinforcing fibers to be coupled to theknitted web 110. When the adhesive is used, a bonding force between the reinforcingportion 120 and theknitted web 110 may be further increased. - The upper reinforcing
layer 121 may be formed by layering reinforcing fibers on the upper surface of the knittedweb 110. The upper reinforcinglayer 121 may be formed to have a predetermined thickness. The upper reinforcinglayer 121 may be formed to entirely cover the upper surface of the knittedweb 110. The upper reinforcinglayer 121 may be coupled to the yarn while some of the reinforcing fibers are introduced into the yarn. The upper reinforcinglayer 121 may be formed in a region including the upper portion of the yarn and the upper portion of the through hole. The upper reinforcinglayer 121 may be formed to have different thicknesses in the region of the yarn, that is, in the region in contact with the yarn and the upper region of the through hole. The upper reinforcinglayer 121 may be formed such that at least a portion of the yarn is exposed. The upper reinforcinglayer 121 may be formed to have an appropriate thickness according to an amount of reinforcing fiber positioned on the upper portion of the knittedweb 110 during the needling process. The thickness of the upper reinforcinglayer 121 may be adjusted by adjusting the amount of reinforcing fiber used. - The lower reinforcing
layer 122 may be formed by layering reinforcing fibers on the lower surface of the knittedweb 110. The lower reinforcinglayer 122 may be formed to have a predetermined thickness. The lower reinforcinglayer 122 may be formed to entirely cover the lower surface of the knittedweb 110. The lower reinforcinglayer 122 may be coupled to the yarn while a portion of the reinforcing fibers are introduced into the yarn. The lower reinforcinglayer 122 may be formed in a region including a lower portion of the yarn and a lower portion of the through hole. The upper reinforcinglayer 121 may be formed to have different thicknesses in the region of the yarn, that is, in the region in contact with the yarn and the upper region of the through hole. The lower reinforcinglayer 122 may be formed such that at least a portion of the yarn is exposed. The lower reinforcinglayer 122 may be formed to have an appropriate thickness according to the amount of reinforcing fiber positioned below the knittedweb 110 during the needling process. - The lower reinforcing
layer 122 may be formed by filling the inner side of the through hole of the knittedweb 110 with reinforcing fibers. In addition, the lower reinforcinglayer 122 may be formed so that some of the reinforcing fibers introduced into the yarn of the knittedweb 110. That is, the lower reinforcinglayer 122 may be positioned so that the reinforcing fibers penetrate into the yarn. The lower reinforcinglayer 122 is integrally formed with the upper reinforcinglayer 121 and the lower reinforcinglayer 122 and is coupled thereto. Accordingly, the lower reinforcinglayer 122 allows the reinforcingportion 120 to be coupled to theknitted web 110. - The inner reinforcing
layer 123 may be formed by filling the through hole with reinforcing fibers. The inner reinforcinglayer 123 may be integrally formed with the upper reinforcinglayer 121 and the lower reinforcinglayer 122 to fix the upper reinforcinglayer 121 and the lower reinforcinglayer 122. - The
edge layer 124 may be formed such that the reinforcing fibers form a band shape on the edge of the knittedweb 110. Theedge layer 124 may be formed in a band shape while the reinforcing fibers are stretched. Theedge layer 124 may be formed to have a predetermined thickness. Theedge layer 124 may be formed without theknitted web 110 therein. An outer end of theedge layer 124 may be formed in an irregular shape. For example, a distance of theedge layer 124 from the knitted web to the outer end may be irregular. Theedge layer 124 may be formed to surround the periphery of the knittedweb 110. Theedge layer 124 may support the periphery of the knittedweb 110 while being integrally formed with the upper reinforcinglayer 121 and the lower reinforcinglayer 122. Accordingly, theedge layer 124 may prevent the yarn of the knittedweb 110 from being unraveled during use of the knittedfabric 100. In addition, theedge layer 124 supports the edge of the knittedweb 110 so that the knitted web is not unraveled when the yarn of the knittedweb 110 is cut. -
FIG. 6 is a photograph illustrating clothes and accessories made of the knitted fabric of the present disclosure. - Referring to
FIG. 6 , in the cuttable knittedfabric 100 of the present disclosure, theknitted web 110 and the reinforcingportion 120 are entangled with each other as a whole, so that curl-up and loosening of the yarn do not occur after being cut. Through this, the cuttable knittedfabric 100 can be cut into various sizes and various shapes, and thus, the knitted fabric can be used as a material for various products. The cuttable knittedfabric 100 may be used in the production of sweaters, clothing such as coats, handbags, and accessories such as bags. - Hereinafter, a method for manufacturing a cuttable knitted fabric according to one embodiment of the present disclosure will be described.
-
FIG. 7 is a process diagram of the method for manufacturing a cuttable knitted fabric according to one embodiment of the present disclosure. - Referring to
FIGS. 1 and 7 , the method for manufacturing a cuttable knitted fabric includes a step S10 of providingknitted web 110, a step S20 of disposing reinforcing fiber, and a step S30 of coupling theknitted web 110 and the reinforcing fiber. The method for manufacturing a knitted fabric may further include a step S40 of post-treatment applying moisture and heat to the needle fabric. - The step S10 of providing the
knitted web 110 is a step of preparing theknitted web 110. Theknitted web 110 may have an appropriate size and shape according to the required fabric. Theknitted web 110 may be formed in a plate shape. Theknitted web 110 may be formed by weaving a single yarn. - The step S20 of disposing the reinforcing fibers is a step of disposing the reinforcing fibers on the upper and lower surfaces of the knitted
web 110. As the reinforcing fibers, a member having entanglement such as a woolen material or cotton may be used. Preferably, the reinforcing fibers may be sequentially disposed on the upper and lower surfaces of the knittedweb 110. For example, the reinforcing fibers may be first disposed on the upper surface of the knittedweb 110, and the reinforcing fibers may be disposed on the lower surface of the knittedweb 110 in an inverted state. Alternatively, the reinforcing fiber may be first disposed on a separate plate, and after theknitted web 110 is disposed on the reinforcing fiber, the reinforcing fiber may be disposed on the upper surface of the knittedweb 110 again. The reinforcing fibers may be disposed on the edge of the knittedweb 110 in addition to the upper and lower surfaces. The reinforcing fibers may be stacked on theknitted web 110 as a whole. The reinforcing fibers may be stacked in at least one bundle according to the total area of the knitted web. In addition, the reinforcing fibers may be entirely stacked on theknitted web 110 in a plurality of small bundles. A bundle of a plurality of reinforcing fibers disposed on the upper surface of the knittedweb 110 may be disposed to be alternately disposed with a bundle of reinforcing fibers disposed on a lower surface of the knittedweb 110. - The step S30 of coupling the
knitted web 110 and the reinforcing fiber is a step of forming a needle fabric by coupling the reinforcing fiber to theknitted web 110. The step of coupling theknitted web 110 with the reinforcing fiber may be a needling process. The reinforcing fibers disposed on the upper and lower surfaces of the knittedweb 110 may be coupled to theknitted web 110 through the needling process. In this case, the needling process may be performed while supplying a separate adhesive to the reinforcing fibers and theknitted web 110. The adhesive may increase bonding strength between the reinforcing fibers and theknitted web 110. The needling process may be performed while repeatedly passing the needle through theknitted web 110 on which the reinforcing fibers are disposed. The needle may be a felt needle. The reinforcing fibers need to be uniformly coupled to theknitted web 110. In order for the needle fabric to be cuttable, it is necessary that the needling process be performed with a consistent force and a consistent amount. The needling process may be preferably performed using a needling device. Meanwhile, the needling process may be performed as a general needling process. The needling process may be repeated in a state where the upper surface of the knittedweb 110 faces upward, and in addition, the process proceeds again with the lower surface of the knittedweb 110 facing upward. Through the reinforcing fiber coupling step, the knitted fabric may be formed with an upper reinforcing layer, a lower reinforcing layer, and an inner reinforcing layer on theknitted web 110. In addition, the knitted fabric may be formed with anedge layer 124 surrounding the periphery of the knittedweb 110. - The post-treatment step S40 is a step of performing by supplying moisture to the needle fabric and applying a predetermined temperature to perform drying and curing. The post-treatment step may be performed by an appropriate method depending on the use of the knitted fabric.
- As an example, the cuttable knitted
fabric 100 may be treated by immersion in water. In this case, hot water and cold water may be used as the water. Here, the hot water is water having a temperature higher than room temperature, and may be water of 40 to 80° C. The cold water is water having a temperature lower than room temperature, and may be water of 10 to 20° C. The cuttable knittedfabric 100 may be treated by alternately immersing theknitted fabric 100 in hot and cold water. The cuttable knittedfabric 100 may be shrunk in advance through the post-treatment. Accordingly, the cuttable knittedfabric 100 may be reduced in shrinkage during use. - In addition, in the post-treatment step, the cuttable knitted
fabric 100 may be treated by spraying water or spraying high-temperature and high-pressure steam. - In addition, the cuttable knitted
fabric 100 may be immersed in a soap solution and rubbed against each other. The soap solution may be maintained at a temperature of 40 to 80° C. The cuttable knittedfabric 100 is rubbed against each other in a state of being immersed in the soap solution, the reinforcing fibers are tangled, and thus, the bonding force between the reinforcing fibers and theknitted web 110 may be increased. In addition, the cuttable knittedfabric 100 may be immersed in soap solution and contracted while rubbing and thickened. The cuttable knittedfabric 100 may have a dense texture and a softer feel. -
FIG. 8 is a photograph illustrating a cuttable knittedfabric 200 according to one embodiment of the present disclosure.FIG. 9 is a photograph illustrating an example of a cross-section of the cuttable knittedfabric 200 that is cut along a line “B” illustrated inFIG. 8 . - Referring
FIGS. 8 and 9 , the cuttable knittedfabric 200 according to one embodiment of the present disclosure may include aknitted web 210, a first reinforcingportion 220, and a second reinforcingportion 230. In the cuttable knittedfabric 200, the first reinforcingportion 220 and the second reinforcingportion 230 may be coupled to one of a front surface (or upper surface) and a back surface (or lower surface) of the knittedweb 210. - As an example, in the cuttable knitted
fabric 200, the first reinforcingportion 220 and the second reinforcingportion 230 may be coupled to the back surface (or lower surface) of the knittedweb 210 to increase tensile strength. The first reinforcingportion 220 and the second reinforcingportion 230 may be formed of different materials and may have different tensile strengths. As an example, the first reinforcingportion 220 may have a high tensile strength in an X-axis direction, and the second reinforcingportion 230 may have a high tensile strength in a Y-axis direction. As an example, the first reinforcingportion 220 may have a high tensile strength in the Y-axis direction, and the second reinforcingportion 230 may have a high tensile strength in the X-axis direction. -
FIG. 10A is a view illustrating the knitted web of the cuttable knitted fabric and an arrangement form of the first reinforcing portion and the second reinforcing portion according to one embodiment of the present disclosure. - Referring to
FIGS. 8, 9, and 10A , the first reinforcingportion 220 may be disposed to correspond to a partial region of the back surface (or lower surface) of the knittedweb 210. As an example, the first reinforcingportion 220 may be disposed to correspond to a central portion of the back surface (or lower surface) of the knittedweb 210. - The second reinforcing
portion 230 may be disposed to correspond to a partial region of the back surface (or lower surface) of the knittedweb 210. As an example, the second reinforcingportion 230 may be disposed to correspond to an edge of the back surface (or lower surface) of the knittedweb 210. The second reinforcingportion 230 may be disposed to surround the periphery of the first reinforcingportion 220. - The first reinforcing
portion 220 and the second reinforcingportion 230 may be formed of different materials. The first reinforcingportion 220 disposed to correspond to the central portion of the knittedweb 210 may be formed of a fiber material having a cushioning feeling and soft characteristics. The second reinforcingportion 230 disposed to correspond to the edge of the knittedweb 210 may be formed of a fibrous material having high rigidity to prevent theknitted web 210 from being unraveled. - In
FIG. 10A , the first reinforcingportion 220 and the second reinforcingportion 230 are illustrated as having a circular shape. However, the present disclosure is not limited thereto, and the shapes of the first reinforcingportion 220 and the second reinforcingportion 230 may be variously changed according to the shape of the cuttable knitted fabric 200 (for example, a square, a rhombus, a trapezoid, or the like). - Again, referring to
FIG. 9 , the first reinforcingportion 220 and the second reinforcingportion 230 may support the knittedweb 210 as a whole to prevent curl-up from occurring. In addition, in the cuttable knittedfabric 200, the first reinforcingportion 220 and the second reinforcingportion 230 are coupled to theknitted web 210, and thus, the yarn of the knittedweb 210 and the reinforcing fibers constituting the first reinforcingportion 220 and the second reinforcingportion 230 are entangled with each other. Since the first reinforcingportion 220 and the reinforcingportion 230 fix theknitted web 210, the yarn is not unraveled even when the yarn of the knittedweb 210 is cut during the cutting process. In addition, since the cuttable knittedfabric 200 is formed by having the knittedweb 210 as a basic skeleton and coupling the first reinforcingportion 220 and the second reinforcingportion 230 using reinforcing fibers as a material, theknitted fabric 200 has good elasticity and flexibility and does not wrinkle. Theknitted web 210 may be formed by being woven in a substantially plate shape using a single yarn. -
FIG. 10B is a view illustrating the knitted web of the cuttable knitted fabric and an arrangement form of the first reinforcing portion and the second reinforcing portion according to one embodiment of the present disclosure. - Referring to
FIG. 10B , shapes of a first reinforcing portion 220-1 and a second reinforcing portion 230-1 may be variously changed according to the shape of the cuttable knitted fabric 200-1. As an example, the knitted web 210-1 may be formed in a rectangular shape (for example, a square shape, a rectangular rigid shape), and the first reinforcing portion 220-1 and the second reinforcing portion 230-1 may be formed in an elliptical shape. That is, the knitted web 210-1, the first reinforcing portion 220-1, and the second reinforcing portion 230-1 may be formed in different shapes. - The first reinforcing portion 220-1 may be disposed to correspond to a central portion of a back surface (or lower surface) of the knitted web 210-1. The second reinforcing portion 220-2 may be disposed to correspond to an edge of the back surface (or lower surface) of the knitted fabric 21-1. The second reinforcing portion 230-1 may be disposed to surround the periphery of the first reinforcing portion 220-1.
- The first reinforcing portion 220-1 and the second reinforcing portion 230-1 may be formed of different materials. The first reinforcing portion 220-1 disposed to correspond to the central portion of the knitted web 210-1 may be formed of a fiber material having a cushioning feeling and soft characteristics. The second reinforcing portion 230-1 disposed to correspond to the edge of the knitted web 210-1 may be formed of a fiber material having a strong characteristic so that the knit of the knitted web 210-1 is not unraveled.
-
FIG. 10C is a view illustrating the knitted web of the cuttable knitted fabric and an arrangement form of the first reinforcing portion, the second reinforcing portion, and a third reinforcing portion according to one embodiment of the present disclosure. - The first reinforcing portion 220-2, a second reinforcing portion 230-2, and a third reinforcing portion 240-2 having different shapes may be disposed on a back surface (or lower surface) of the knitted web 210-2. As an example, the first reinforcing portion 220-2 may be formed in a circular shape. The second reinforcing portion 230-2 may be formed in a rhombus shape. The third reinforcing portion 240-2 may be formed in an elliptical shape.
- The first reinforcing portion 220-2 may be disposed to correspond to the central portion of the knitted web 210-2. The second reinforcing portion 230-2 may be disposed to surround the periphery of the first reinforcing portion 220-2. The third reinforcing portion 240-2 may be disposed around the second reinforcing portion 230-2.
- The first reinforcing portion 220-2, the second reinforcing portion 230-2, and the third reinforcing portion 240-2 may be formed of different materials. The first reinforcing portion 220-2 disposed to correspond to the central portion of the knitted web 210-2 may be formed of a fiber material having cushioning and soft properties. The second reinforcing portion 230-2 disposed to correspond to the edge of the knitted web 210-2 may be formed of a fiber material having high rigidity to prevent the knit of the knitted web 210-2 from being unraveled. The third reinforcing portion 240-2 disposed around the second reinforcing portion 230-2 may be formed of a fibrous material having high rigidity to prevent the knit of the knitted web 210-2 from being unraveled. Here, directions of tensile strengths of the second reinforcing portion 230-2 and the third reinforcing portion 240-2 are formed to be different from each other. Accordingly, even when the knitted web 210-2 extends in the X-axis direction, the Y-axis direction, and the diagonal direction, it is possible to maintain the shape of the knitted web 210-2 and prevent the knit of the knitted web 210-2 from being unraveled.
- The yarn of the knitted
web 210, 210-1, or 210-2 may include wool, lana merino wool, nylon, polyamide, or acrylic. - The present disclosure is not limited thereto, and the yarn of the knitted
web 210, 210-1, or 210-2 may include a mixed blend obtained by mixing at least two of wool, lana merino wool, nylon, polyamide, and acrylic. - The present disclosure is not limited thereto, and the yarn of the knitted
web 210, 210-1, or 210-2 may include a mixed blend obtained by mixing wool of 35%, polyamide of 25%, and acrylic of 40%. - The present disclosure is not limited thereto, and a ratio (%) of materials constituting the yarn of the knitted
web 210, 210-1, or 210-2 may be changed according to clothing and accessories made of the cuttable knittedfabric 200, 200-1, or 200-2. - The
knitted web 210, 210-1, or 210-2 may be produced to have a weaving thickness of 5 mm to 12 mm using a hand knitting machine. A length of the knittedweb 210, 210-1, or 210-2 in the first direction may be formed to be 50 cm to 150 cm, and a length in the second direction may be formed to be 100 cm to 250 cm. The present disclosure is not limited thereto, and length of the knittedweb 210, 210-1, or 210-2 in the first direction and the second direction are not limited. As the size is reduced by steam and heat treatment during the manufacturing process of the cuttable knittedfabric 200, 200-1, or 200-2, in consideration of the reduced length, the length of the knittedfabric 210, 210-1, or 210-2 in the first direction and the second direction may be set. Here, according to the number of needling for mixing theknitted web 210, 210-1, or 210-2 and the reinforcingportions 220, 220-1, 220-2, 230, 230-1, 230-2, and 240-2, the number of heating and the heating temperature for theknitted web 210, 210-1, or 210-2 and reinforcingportions 220, 220-1, 220-2, 230, 230-1, 230-2, and 240-2, and the number of steaming and the steam temperature applied to theknitted web 210, 210-1, or 210-2 and the reinforcingportions 220, 220-1, 220-2, 230, 230-1, 230-2, and 240-2, the ratio % of reduced lengths in the first direction and the second direction may be changed. - As an example, during the manufacturing process of the cuttable knitted
fabric 200, 200-1, or 200-2, the lengths in the first direction and the second direction may be reduced by approximately 20%. In this case, in order to form the cuttable knittedfabric 200, 200-1, or 200-2 having a length of 100 cm in the first direction and 150 cm in the second direction, theknitted web 210, 210-1, or 210-2 and the reinforcingportions 220, 220-1, 220-2, 230, 230-1, 230-2, and 240-2 may have a length of 120 cm in the first direction and a length of 180 cm in the second direction. By performing the manufacturing process using the knittedweb 210, 210-1, or 210-2 and the reinforcingportions 220, 220-1, 220-2, 230, 230-1, 230-2, and 240-2 having the length of 120 cm in the first direction and 180 cm in the second direction, it is possible to form the cuttable knittedfabric 200, 200-1, or 200-2 having the length of 100 cm in the first direction and the length of 150 cm in the second direction. - The cuttable knitted
fabric 200, 200-1, or 200-2 may include the plurality of knittedwebs 210, 210-1, or 210-2 woven by one yarn. In this case, theknitted web 210, 210-1, or 210-2 may be arranged so that side surfaces of knitted web are in contact with each other or are spaced apart from each other in the cuttable theknitted fabric 200, 200-1, or 200-2. In this case, the plurality of knittedwebs 210, 210-1, or 210-2 may be fixed to be coupled to one of the reinforcingportions 220, 220-1, 220-2, 230, 230-1, 230-2 and 240-2. - The reinforcing
portions 220, 220-1, 220-2, 230, 230-1, 230-2, and 240-2 may be formed so that the reinforcing fibers positioned below the knittedweb 210, 210-1, or 210-2 are coupled to theknitted web 210, 210-1, or 210-2. The reinforcing fibers of the reinforcingportions 220, 220-1, 220-2, 230, 230-1, 230-2, and 240-2 may be formed of a material having its own entanglement such as a fine fiber, a thread, or a fiber thinner than the yarn. - As an example, the reinforcing fibers may be formed of wool (woolen material, lamb's wool, merino wool, pima wool), cotton wool, or poly (for example, nylon) cotton.
- As an example, the reinforcing fibers may be formed by mixing two or more materials selected from wool (woolen material, lamb's wool, merino wool, pima wool), cotton, and poly (for example, nylon) cotton.
- The reinforcing fibers of the reinforcing
portions 220, 220-1, 220-2, 230, 230-1, 230-2, and 240-2 have a property of being entangled with each other, and the reinforcing fibers are introduced into the yarn of the knittedweb 210, 210-1, or 210-2 and entangled, and thus, may be coupled to the yarns of the knittedweb 210, 210-1, or 210-2. The reinforcing fibers of the reinforcingportions 220, 220-1, 220-2, 230, 230-1, 230-2, and 240-2 may fix the yarns of the tissues of the knittedweb 210, 210-1, or 210-2 while filling the inside or the tissues of the knittedweb 210, 210-1, or 210-2. Since the reinforcing fibers are thinner than the yarns of the knittedfabrics 210, 210-1, or 210-2, the reinforcing fibers may be easily introduced into the yarns. The reinforcing fiber may be coupled to theknitted web 210, 210-1, or 210-2 so that the reinforcingportions 220, 220-1, 220-2, 230, 230-1, 230-2, and 240-2 are formed, and theknitted web 210, 210-1, or 210-2 may be coupled to the reinforcingportions 220, 220-1, 220-2, 230, 230-1, 230-2, and 240-2 so that a cuttable knittedfabric 200, 200-1, or 200-2 is formed. - The reinforcing fibers of the reinforcing
portions 220, 220-1, 220-2, 230, 230-1, 230-2, and 240-2 can prevent the knit of the knittedweb 210, 210-1, or 210-2 from being unraveled when theknitted web 210, 210-1, or 210-2 is cut. The reinforcingportions 220, 220-1, 220-2, 230, 230-1, 230-2, 240-2 may reduce the unraveling of the knittedweb 210, 210-1, or 210-2. In addition, the reinforcing fibers of the reinforcingportions 220, 220-1, 220-2, 230, 230-1, 230-2, and 240-2 are coupled to knittedweb 210, 210-1, or 210-2, and thus, theknitted fabric 200, 200-1, or 200-2 can maintain a constant shape. - Meanwhile, an adhesive such as a paste may be fixed with the reinforcing fibers of the reinforcing
portions 220, 220-1, 220-2, 230, 230-1, 230-2, and 240-2 and needled, and thus, the reinforcing fibers can be coupled to theknitted web 210, 210-1, or 210-2. When the adhesive is used, it is possible to further increase the bonding force between the reinforcingportions 220, 220-1, 220-2, 230, 230-1, 230-2, 240-2 and theknitted web 210, 210-1, or 210-2. - The cuttable knitted
fabric 200, 200-1, or 200-2 of the present disclosure can be cut into various sizes and shapes, and thus, the knitted fabric can be used as a material for various products. As illustrated inFIG. 6 , the cuttableknitted fabrics 200, 200-1, or 200-2 may be used in the manufacture of clothing such as a sweater or a coat, a handbag, and accessories such as bags. -

A length of the knittedweb 210 in the first direction may be formed to be 50 cm to 150 cm, and a length in the second direction may be formed to be 100 cm to 250 cm. The present disclosure is not limited thereto, and the length of the knittedweb 210 in the first direction and the second direction is not limited. As the size is reduced by steam and heat treatment during the manufacturing process of the cuttable knittedfabric 200, in consideration of the reduced length, the length of the knittedweb 210 in the first direction and the second direction may be set. - Subsequently, the step S120 of disposing the first reinforcing fiber is a step of disposing the first reinforcing fibers at regular intervals on the lower surface of the knitted
web 210. The first reinforcing fibers may be disposed to correspond to the central portion of the lower surface of the knittedweb 210. The first reinforcingportion 220 may be formed through the first reinforcing fibers. - The first reinforcing fibers of the first reinforcing
portion 220 may be formed of a material having its own entanglement such as a fine fiber, a thread, or a fiber thinner than the yarn. - As an example, the first reinforcing fibers of the first reinforcing
portion 220 may be formed of wool (woolen material, lamb's wool, merino wool, pima wool), cotton wool, or poly (for example, nylon) cotton. - As an example, the first reinforcing fibers of the first reinforcing
portion 220 may be formed by mixing two or more materials selected from wool (woolen material, lamb's wool, merino wool, pima wool), cotton, and poly (for example, nylon) cotton. - As an example, in order to increase the tensile strength in the first direction of the cuttable knitted
fabric 200, the first reinforcingportion 220 may be formed of the first reinforcing fibers obtained by mixing 50% to 70% poly (for example, nylon) cotton and 30% to 50% wool (woolen material, lamb's wool, merino wool, pima wool). - As an example, in order to increase the tensile strength in the first direction of the cuttable knitted
fabric 200, the first reinforcingportion 220 may be formed of the first reinforcing fibers obtained by mixing 50% to 70% poly (for example, nylon) cotton and 30% to 50% cotton. - As an example, in order to increase the tensile strength in the first direction of the cuttable knitted
fabric 200, the first reinforcingportion 220 may be formed of the first reinforcing fibers obtained by mixing 40% to 60% poly (for example, nylon) cotton, 20% to 30% wool (woolen material, lamb's wool, merino wool, pima wool), and at 20% to 30% cotton. - Subsequently, the step S130 of disposing the second reinforcing fiber is a step of disposing the second reinforcing fibers on the edge of the lower surface of the knitted
web 210. The second reinforcing fiber may be disposed to surround the periphery of the first reinforcingportion 220. The second reinforcingportion 230 may be formed through the second reinforcing fibers. - The second reinforcing fibers of the second reinforcing
portion 230 may be formed of a material having its own entanglement such as a fine fiber, a thread, or a fiber thinner than the yarn. - As an example, the first reinforcing fibers of the second reinforcing
