Description

[Detailed Description of the Invention] (Industrial field of application) The present invention relates to a pile woven or knitted fabric suitable for car seats or upholstery materials, as well as general clothing applications that are excellent in surface quality, gloss and warm feeling. It is a thing.

(Prior Art) Conventionally, a pile woven or knitted fabric in which a crimped yarn or a non-crimped yarn of multifilament is used as a pile yarn is well known. The crimped yarn in that case, whether used alone or as a non-crimped yarn and an aligned composite yarn, has a normal false twist number (the denier number of the crimped yarn is D
And the false twist number (T / M) is T, It means false twist represented by. However, a = 1.0 to 1.3)
Was a crimped yarn.

(Problems to be solved by the invention) However, these conventional pile woven and knitted fabrics have problems such as ground cracks, warps, shrinkage of piles, defective pile morphology, etc., which cause deterioration of surface quality, and dents and folds. Had a problem of poor glossiness and light reflectivity that makes it look whitish or dull, and lack of softness, swelling, and warm feeling.

The present invention solves the above problems, and has excellent surface quality, high-grade gloss and appropriate light reflectivity, and also has good softness, swelling, and warm touch, for clothing and car. The purpose is to provide pile woven and knitted fabrics suitable for seats and upholstery.

(Means for Solving Problems) That is, according to the present invention, a usual thermoplastic synthetic fiber multifilament yarn for clothing is false twisted and crimped at a low false twist number of 85 to 40% of the usual false twist number. A low-twisted crimped yarn that is made up of the above and a non-crimped yarn that is substantially non-twisted and does not have crimps or torques and is a non-crimped yarn of ordinary multifilament A pile woven or knitted fabric characterized in that a pile is formed on the fabric.

The pile woven or knitted fabric according to the present invention will be described in detail below.

FIG. 1 (a) and FIG. 1 (b) are partial side views of an embodiment of the pile woven or knitted fabric of the present invention. (A) The figure shows cloth (M)
, Which has a loop pile (P1) on one side thereof, and the pile (P1) is made of a thermoplastic synthetic fiber multifilament yarn for clothing, which has a low false twist number of 85 to 40%, preferably 80 to 50%. Low false-twist crimped yarn (hereinafter referred to as "low false-twist crimped yarn") formed by false-twist crimping with the number of false twists, and a normal multifilament for clothing having substantially no crimp or torque. Non-crimped yarns (hereinafter referred to as "non-crimped yarns"), and mixed the single false filament (F1a) of the low false twist crimped yarn with the non-crimped single yarn filament (F1b). It is formed from a composite thread (F1ab) that is made by fiberizing. Also (b)
The figure shows a cloth (N) having a cut pile (Pc) on one side, and the pile (Pc) is the loop pile (Pc).
As in the case of 1), the low false twist crimped yarn and the non-crimped yarn are aligned and the single false filament (Fc
It is formed of a composite yarn (Fcab) in which a) and the non-crimped single yarn filament (Fcb) are mixed.

Although both (a) and (b) are so-called single-sided piles having a pile on one side of the cloth, the pile woven or knitted fabric of the present invention may be a so-called double-sided pile having a pile on both sides of the cloth.
Further, the thermoplastic synthetic fiber multifilament yarn used for the low false twist crimped yarn may be any thermoplastic synthetic fiber multifilament yarn such as polyester or polyamide, and the above-mentioned non-crimped multifilament yarns may be used. A thermoplastic synthetic fiber multifilament yarn similar to that used for the low false twist crimped yarn, or any kind of semisynthetic fiber or recycled fiber multifilament yarn may be used.

Also, the reason why the number of false twists added to the thermoplastic synthetic fiber multifilament yarn is set to 85 to 40% of the normal false twist number is that if it exceeds 85%, the crimpability is excessively increased, and therefore the formation This is because the morphology of the pile becomes unstable and pile shrinkage occurs, which lowers the surface quality of the woven and knitted pile and also makes the gloss extremely inferior. On the other hand, when it is less than 40%, The reason is that it is difficult to impart crimping property and it becomes similar to non-crimped yarn, and ground cracks and warps occur, and the luster becomes metallic.

Furthermore, the number of false twists is 85 to 40, which is the normal number of false twists as described above.
By limiting the content to%, the openability of the crimped filaments can be enhanced in the subsequent air jet treatment, and the effect of significantly improving the mixing ability with the non-crimped filaments can be achieved.

In the pile-formed composite yarn, the single yarn filaments of the low false twist crimped yarn and the single yarn filaments of the non-crimped yarn, which are the constituent yarns, are mixed. Is
The composite yarn is arranged so as to be randomly distributed in the cross section of the composite yarn.

That is, the single filaments of the same kind do not gather in a large amount in one place, and the single filaments of the crimped yarn are dispersed and arranged between the single filaments of the non-crimped yarn. However, at that time, it is preferable that the single yarn filaments are not tightly focused, but relatively lightly focused. Such a form is specifically obtained by performing an air jet treatment using a general filament yarn for clothing. In that case, it is important to take measures as much as possible so that a strong entangled portion is not formed in the longitudinal direction of the yarn.

Here, in order to efficiently and randomly disperse the crimped single filaments and the non-crimped filaments, the single yarn fineness of both filaments is preferably 5 denier or less.
When the single yarn fineness exceeds 5 denier, each single filament becomes difficult to move, which causes a drawback that not only good blending property is not obtained but also softness is not obtained.

A loop may or may not be formed in the air jet process.

(Operation) In the pile woven or knitted fabric of the present invention, the composite yarn forming the pile is composed of the low false twist crimped yarn and the non-crimped yarn, and the single yarn filaments of both the constituent yarns are formed by the cross section of the composite yarn. Since the fibers are mixed in such a manner that they are dispersed and arranged as randomly as possible, the crimp characteristics of the low false twist crimped yarn and the smoothness and rigidity of the non-crimped yarn are combined. And gives the pile formed good softness and a feeling of swelling and warm touch,
In addition, the high gloss and deep color tone are imparted to the fabric surface by its excellent gloss and appropriate light reflectivity, and the pile woven and knitted fabric has a new texture and graceful appearance that never existed before. It is what makes me.

(Example) A polyester false filament yarn 100d / 48f is false twisted at a false twist number of 1800 T / M which is a false twist number corresponding to 72 to 55% of the normal false twist number to obtain a low false twist crimped yarn, The processed yarn and the non-crimped polyester multi-filament yarn 75d / 48f are aligned and fed at an overfeed rate of 4%,
The fibers were treated with a Taslan nozzle having a fluid pressure of 4 kg / cm ² , and were mixed so as to randomly disperse the single-filament filaments of the low false twist crimped yarn and the single-filament filaments of the non-crimped yarn. A composite yarn was obtained. Using the composite yarn as a pile yarn,
A commercially available 20G double-rattle cell knitting machine knitted a pile knitted fabric having a pile density of 420 pieces / in ² . The obtained pile knitted fabric was center cut to form a cut pile knitted fabric having a pile height of 5 mm, and the knitted fabric was subjected to a usual dyeing process.

The obtained cut pile knitted fabric has a luxurious and elegant luster and deep color tone with proper surface reflection without cracks and warps, and also has appropriate light reflectivity and softness, swelling and warm touch. It was a good pile knit product.

(Effect of the Invention) Since the pile woven and knitted fabric of the present invention has the above-mentioned structure,
It has an excellent surface quality with no cracks in the ground, warp lines or puckering, and has a luxurious and elegant luster and appropriate light reflectivity, as well as good softness, swelling and warm touch. Therefore, in addition to general clothing applications, it is a pile woven and knitted fabric with high practical value, which is particularly suitable for car seats and upholstery materials that require excellent luster and light reflectivity, in which the fabric has many bends. .
