The preparation method of the core-spun woolen fabric comprises the following steps:
(1) feeding the wool fibers 13 into a core-spun wool fabric weaving device to be ready for winding and weaving with the bottom yarns 1;
(2) the latch 2 of the core-spun woolen fabric weaving device is turned downwards, the needle hook 11 is opened, and the plush fibers 13 are completely covered in the opened needle hook 11;
(3) the magnetic device 202 of the core-spun woolen fabric weaving device attracts the latch 2, tightly attaches the latch 2 in a downward overturning state to one side of the needle bar 5, avoids a large gap between the latch 2 and the lower part of the needle bar 5, and ensures that a maximum opening angle is formed between the latch 2 and the needle hook 11;
(4) the knitting needle 7 of the core-spun woolen fabric knitting device moves downwards, the latch 2 overcomes the attraction of the magnetic device 202 under the support of the looped old pile loop 101, and the pile fibers 13 are completely wrapped inside the needle hook 11, so that the knitting of the pile fibers 13 and the bottom yarns 1 is completed;
(5) the terry 101 formed by the plush fibers in the step (4) is tightly attached to the outer surface of the fabric, the middle section of the plush fibers 13 forms a terry middle wrapping and winding part 103, and the terry middle wrapping and winding part 103 and the bottom yarn 1 are attached to the inside of the fabric together;
(6) in the step (5), the tail part of the winding part 103 is coated in the middle of the terry to form a terry fiber tail part 104, and the terry fiber tail part 104 and the ground yarn 1 are continuously attached to the inside of the fabric;
(7) and (5) repeating the steps (1) to (6) to finish the production of the core-spun woolen fabric.
When the core-spun woolen fabric weaving device works, because the magnetic device 202 is arranged on the back of the knitting needle 7, when the core-spun woolen fabric weaving device weaves woolen fiber cloth, the needle cylinder 9 drives the sinker 3 to move horizontally when rotating, the needle cylinder 9 also drives the knitting needle 7 to move up and down, meanwhile, when the latch 2 moves up and down on the knitting needle 7, the latch 2 turns up and down around the pin shaft 8, when the latch 2 turns up and down around the pin shaft 8, the latch 2 repeatedly opens and closes the needle hook 11, the latch 2 of the knitting needle 7 can be under the action of a magnetic field except the action of centrifugal force, keeps the state of turning down, the latch 2 is always close to the needle bar 5, no gap exists between the latch 2 and the needle bar 5, the woolen fiber 13 cannot be left in the gap between the latch 2 and the needle bar 5, the latch 2 is pushed by the old woolen loop 4 to turn up, when the needle bar 5 and the latch 2 move down, the tail of the old woolen fiber 4 is not blocked under the latch 2, all the fiber tails of the old looped piles 4 are arranged on the needle tongues 2 and are completely wrapped by the needle hooks 11, the fiber tails of the old looped piles 4 are further close to the needle bars 5 under the action of auxiliary blowing air flow generated by the air flow generator 10 and are woven into looped piles 101 together with the bottom yarns 1, all the fiber tails of the old looped piles 4 are wrapped on the newly fed bottom yarns 1 and are woven into loops together with the new bottom yarns 1, the loops are woven into the bottom gauze 100 without influencing the looping height of the new looped piles 101, the new looped piles 101 are adhered to the bottom gauze 100 and are in an approximately flat cloth shape, wool fibers 13 cannot leak on the lower surface of the wool cloth, the looped piles 101 are woven in the wool fiber cloth, the number of loops which leak on the outer surface is small, the weaving density is high, the looped piles 101 adhered to the outer surface of the wool cloth are not easy to be pulled apart and are not easy to be ground apart, the surface is flat, the pilling resistance is high, the plush fiber cloth has high strength, good hand feeling and stable quality.
After the fiber bundles of the wool fabric fibers 13 are knitted into the terry 101, the fiber bundle starting part of the wool fabric fibers 13 forms a terry starting part 102, redundant wool fabric fibers 13 form a terry middle covering winding part 103, the terry middle covering winding part 103 continuously participates in the knitting of the base fabric, as the wool fabric fibers 13 are completely covered by the needle hooks 11, the terry starting part 102 is tightly wound with the bottom yarn 1, a high terry 101 cannot be formed on the upper surface of the fabric, meanwhile, the terry middle covering winding part 103 is continuously wound with the bottom yarn 1, the subsequent knitting is completed, the terry middle covering winding part 103 forms multiple bends in the base fabric, the wool fibers 13 of the terry middle covering winding part 103 rub and self-lock in the base fabric, the wool fibers 13 are not easy to be pulled out, the knitted fabric has good anti-pilling resistance, and reaches 4 grades through actual tests, while the knitting method of the existing device is not as large as 3 grades, some require the addition of an anti-pilling aid before grade 3 can be achieved.
The fiber bundle of the pile fibers 13 wraps the ground yarn 1 in a wrapping state, which is equivalent to a core-spun yarn, and the ground yarns of the fabric are wrapped inside, so that the fabric has good hand feeling, the thickness and the rigidity of the base fabric are increased, and the drapability of the fabric is correspondingly changed; the excess fiber after the pile fiber 13 fiber bundle is looped participates in the base fabric weaving, so that the strength of the base fabric can be enhanced, and the use ratio of the base yarn 1 can be reduced.
The pile fiber 13 fiber bundle does not form the pile loop 103 twice, the looping height of the next fiber bundle is not influenced, the height of the pile loop on the back of the knitted fabric is extremely low, the pile loop is generally 1-2mm high through testing, the pile loop 103 on the front of the fabric is clear, and the fabric effect is similar to that of a woolen sweater.
The two surfaces of the fabric are both fluffy fibers, when the fabric is used for multi-layer composite use, glue is easy to permeate, and the fibers are in direct contact with the glue, so that the bonding is firmer.
The fabric can be woven by multicolor jacquard at will, and the fabric with more than three colors still keeps the same lightness and thinness as plain yarn dyed fabric. The multicolor jacquard weaving of the traditional woolen sweater, woolen cloth and other knitted fabrics is thicker than plain color fabrics, and the thicker the color is, the harder the fabric is.
Because the spinning process is not carried out in advance, loose fibers directly wrap the core with the bottom yarn 1 and directly participate in weaving, the whole process flow is shortened, and energy is saved and consumption is reduced. The production cycle of the product is short, and the method is suitable for small-batch fast-paced personalized production.
However, the above description is only exemplary of the present invention, and the scope of the present invention should not be limited thereby, and the replacement of the equivalent components or the equivalent changes and modifications made according to the protection scope of the present invention should be covered by the claims of the present invention.
