<Industrial Application Field> This invention relates to a knit-like nonwoven fabric with knit-like knitting on one side, and is particularly suitable for use in clothing, automobile interior materials, etc. Regarding nonwoven fabrics. <Conventional technology> In general, nonwoven fabrics are sheet-like fiber aggregates made by stacking short fibers and entangling them with each other. The disadvantages were that the texture was rough and the abrasion resistance was low. Furthermore, it is a well-known fact that it has poor stretchability and drapability. On the other hand, knitted fabric is an aggregate made of knitted thread-like materials, and while it has excellent stretchability, a fine surface finish, and excellent design effects, it has the problem of poor cushioning properties in the thickness direction. Therefore, the same applicant as the present application is
In No. 79259, the fibers of the web are needle-processed using a stitching needle to form a large number of chain-like loop rows on one side of the web, and a short fiber entangled layer on the other side of the web. Therefore, we have proposed a knit-like nonwoven fabric that is rich in cushioning properties, has increased surface abrasion resistance, and has a finely textured surface finish. <Problems to be solved by the invention> However, the knit-like nonwoven fabric with such a structure has poor surface abrasion resistance compared to ordinary nonwoven fabrics that do not have many chain-like loop rows on the surface. However, when used in areas that frequently come into contact with other parts and undergo repeated friction, there are still problems with wear resistance such as pilling and fizzing. . <Means for solving the problem> This invention was made to solve the above problem, and the fibers of the web are needle-processed on one side with a stitching needle to form a chain-like array of many loops. and a short fiber entangled layer on the other side of the web, the fibers constituting the web include 3 to 50 low melting point fibers.
% by weight, regular fibers are mixed at a ratio of 97 to 50% by weight, and the fabric is heat-treated at a temperature higher than the melting point of the above-mentioned low-melting point fibers and lower than the melting point of the above-mentioned regular fibers. . The present invention will be further described in detail below based on embodiments shown in the drawings. Figures 1 and 2 show the structure of the highly abrasion-resistant knitted nonwoven fabric of this invention. It is composed of a short fiber entangled layer 3. The constituent fibers of the web 11 forming the highly abrasion-resistant knit-like nonwoven fabric 1 are composed of 3 to 50% by weight of low melting point fibers 5 and 97 to 50% by weight of regular fibers 6, and the low melting point fibers 5 are relatively low melting point fibers. melting point e.g. 110
Short fibers of ~130°C can be used. As the regular fiber 6, short fibers having a relatively high melting point, for example, 160 to 230°C can be used, and these fibers 5 and 6 can have a fineness of
1.5~30d, cut length 51~128mm, area weight 80~
The cotton is rolled and laminated to the desired thickness at 300g/ m2 . The chain stitch pattern 2 is given a required stitch length by the stitching needle 16 and is formed into a chain stitch loop, and the tip of the loop is entangled with the fiber aggregate of the short fiber entangled layer 3 at the needling point 8. . In the chain stitch portion 2, both fibers 5 and 6 are brought together in the direction of the chain stitch to form a large number of loops in a row. The formation of this chain-knitted part 2 and short fiber entangled layer 3 is as follows:
Stitching is performed on the web 11 by needle ringing by reciprocating the stitching needle 16. This formation process will be explained with reference to FIGS. 3A to 3C. The stitching needle 16 has a barb 17 at its tip that engages the fibers 5 and 6, moves forward and backward along with the stitching needle 16, and further moves independently back and forth to engage the fibers 5 and 6.
A closing wire 18 is provided for opening and closing the section. First, the stitching needle 16 is attached to the web 11.
enters, and the barb 17 passes through the web 11 and reaches the bottom side in the figure. At this time, the closing wire 18 is in the retracted position (see FIG. 3A). Subsequently, when the stitching needle 16 starts to retreat, the barb 17 engages the fibers 5 and 6 and sinks into the web 11, and the closing wire 18 moves forward to close the barb 17 and is engaged. To ensure that the fibers 5 and 6 are drawn in,
The stitching needle 16 and the closing wire 18 continue to retreat (see FIG. 3B). When the stitching needle 16 reaches the retreating end, the stitching needle 16 comes out of the web 11, and the closing wire 18 retreats to the barb 17. (See Figure 3C).
The fibers 5 and 6 that have been engaged with the barb 17 and drawn into the web 11 and some of the fibers 5 and 6 that have been drawn out of the web 11 are formed into a loop by the barb 17. At this time, the fibers 5 and 6 drawn in at the same time are intertwined with the fibers 5 and 6 in the web 11, and on the bottom side of the figure, a ridge-shaped intertwined short strip is formed with the needling point 8 as a trough. A fiber entangled layer 3 is formed. Then, the web 11 is moved by the stitch length, and a chain stitch portion 2 is formed on the upper surface side, which is stretched and gathered toward the next needling point 8. The above process is repeated to form a continuous chain stitch portion 2. A shaped portion 2 is formed. As described above, the fibers 5 and 6 are on one side of the web 11.
are gathered in the direction of the chain stitch to form a row-like chain-knitted part, and a raw fabric of a knit-like nonwoven fabric is formed in which a short fiber entangled layer 3 having bulkiness is formed on the other side. . Next, the original fabric of this knit-like nonwoven fabric is heat-treated at a temperature higher than the melting point of the low-melting point fibers 5 and lower than the melting point of the regular fibers 6 to melt the low-melting point fibers 5 and release the heat between the fibers 5 and 6. By performing fusion bonding, a highly abrasion-resistant knit-like nonwoven fabric 1 is formed. <Example> Hereinafter, an example of this invention will be described. As a first example, the low melting point fiber 5 was heated at 110°C.
melting point, fineness 4d, cut length 51
40% by weight of core-sheath type polyester fiber in mm, 60% by weight of regular fiber 6 with a melting point of 230℃, fineness of 3D, and cut length of 64mm, both fibers are mixed. A sheet-like web having a basis weight of 230 g/m 2 is formed by steps 5 and 6. Further, a stitching process is performed using a stitching needle with a stitch length of 1.2 mm to form the chain-knitted part 2, and then the needle is heated at 130 to 150°C.
The material is heated for 3 minutes to thermally fuse the low melting point fibers 5 and the regular fibers 6 to form a highly abrasion resistant knit-like nonwoven fabric 1. In addition, as a second embodiment, the low melting point fiber 5
It has a melting point of 130℃, has a fineness of 6d, a cut length of 64mm, uses 10% by weight of side-by-side type polyolefin fiber, and is made into regular fiber 6.
90% by weight of polyolefin fibers having a melting point of 160°C, a fineness of 6d, and a cut length of 64mm are used, and a sheet-like web with a basis weight of 230g/m 2 is formed by mixing both fibers 5 and 6. Ru.
In addition, the stitch length can be adjusted using the stitching needle.
Needling is performed at 1.2 mm to form the chain-knitted part 2, and then heated at 140 to 150°C for 3 minutes to thermally fuse the low-melting point fiber 5 and the regular fiber 6 to form a high-melting point fiber. A wear-resistant knit-like nonwoven fabric 1 is formed. Table 1 shows the Taber abrasion test results of the highly abrasion-resistant nonwoven fabric formed in this way, a conventional knit-like nonwoven fabric formed to the same basis weight and knitting density, and tricot cloth, which is a normal knit product. The knit-like nonwoven fabric formed according to the present invention exhibited superior properties in terms of pill and fuzz generation on the worn surface compared to the comparative material.

大である。[Table] In the above examples, regular fiber 6
When the amount of low-melt fiber 5 mixed in is less than 3% by weight, the formed highly abrasion-resistant knit-like nonwoven fabric 1 has rich cushioning properties, but has improved anti-pilling properties and abrasion resistance compared to conventional knit-like nonwoven fabrics. I couldn't see any. If the amount of the low melting point fiber 5 exceeds 50% by weight, the anti-pilling properties and abrasion resistance will be sufficiently exhibited, but the finish will become paper-like and the cushioning properties will be impaired. In addition, the larger the difference in melting point between the low-melting point fibers 5 and the regular fibers 6, the less the cushioning property is impaired, and furthermore, in application to heat forming described later, the temperature of the heat forming mold can be set relatively widely. It has the advantage of being configurable. Further, even if the low melting point fiber is of a single polymer type, similar actions and effects can be achieved. In addition, the low melting point fiber 5 and the regular fiber 6 are as follows:
It may be a double melting point type core/sheath structural fiber in which the low melting point fiber is on the sheath side and the regular fiber is on the core side, or it may be a double melting point type where one side is made of low melting point fiber and the other side is made of regular fiber. Even if it is a type of side-by-side structural fiber, similar actions and effects can be achieved. FIG. 4 shows an application example in which the highly abrasion-resistant knit-like nonwoven fabric 1 thus formed is further heat-formed. This thermoforming utilizes the thermoplastic properties of the low-melting point fibers 5 of the highly abrasion-resistant knit-like nonwoven fabric 1 as a shape-retaining function, and performs three-dimensional molding using a mold. High abrasion resistant knit-like nonwoven fabric 1 at 140℃ 3
Preheat for minutes followed by cold pressing in a mold with the desired shape. Thereafter, heat molding is performed at 140° C. for 25 seconds using molds 20a and 20b having desired shapes. By this thermoforming, the highly abrasion-resistant knit-like nonwoven fabric 1 is given a desired shape, and the shape is maintained. Incidentally, the same effect can be obtained even if the heat treatment carried out at the time of forming the highly abrasion resistant knit-like nonwoven fabric 1 is omitted and the heat forming is carried out using the above mold. <Effect of the invention> According to the highly abrasion-resistant knit-like nonwoven fabric having the above structure, low melting point fibers are mixed into the fibers constituting the web and heat-treated at 3 to 50 degrees Celsius, so that the entangled fibers are Moreover, the fibers are bonded to each other by the heat-sealing action of the low-melting point fibers, making it possible to significantly improve anti-pilling properties and abrasion resistance. Furthermore, by heat-molding the thermoplastic properties of the low-melting point fibers for shape-retaining function, a desired three-dimensional shape can be formed and excellent shape-retaining properties can be obtained. In addition, a large number of chain-knit loops are formed on one side of the web to form a knit-like chain-knit part, so the surface is dense and a continuous chain-knit pattern is formed. Excellent design effects can be achieved due to the synergistic effect when hues are combined. Furthermore,
Since the short fiber entangled layer is formed on the other side of the web, it has excellent cushioning properties and can exhibit the stretch properties of the chain-knitted portion and the drape properties similar to knitted cloth. In addition, the heat-sealing function of the low-melting point fibers can be brought to light, making it possible to easily form hybrids with other materials.
