Description
The present invention relates to a nylon-polyester-polyurethane mixed yarn excellent in elasticity by using a polyurethane elastic yarn as a core and having a melange effect after dyeing by mixing nylon and polyester yarn, and a manufacturing method thereof .
With the recent increase in income levels and the increased demand and interest in the importance of various functionalities in clothing, a variety of multifunctional textile products are being developed. In particular, woolen or climbing jacket fabrics used for men's and women's formal pants, casual clothes, and sports outdoors which require elasticity are attracting much attention, such as WOOL.
Polyester fabric that is used for men's and women's formal pants, casual clothes and sports outdoors that require elasticity is made of Polyester DTY, To produce a fabric capable of imparting tactile sensation.
Recently, as a result of increasing outdoor activities of consumers in the field of apparel and utilization of clothes as a casual wear, it is possible to provide a new and comfortable appearance and a pleasant and uniform melange tone The development of fabrics with new sensibility.
In order to develop such a soft and clean melange tone and a lightweight fabric having elasticity, it is possible to use melancholy toners using two kinds of materials such as nylon or CDP (Cationic Dyeable Polyester) and general polyester (hereinafter referred to as "PET" And the like. Most of the techniques for imparting stretchability of filament fibers largely depend on the misfire temperature (1st heater temperature) and the stretching ratio given through the DTY (Draw Textured Yarn) process.
Thus, in the Korean Patent Registration No. 10-1459225, an effective air nylon 6 filament yarn is entangled in the air texturing device by the polyester based latent crimping filament yarn, and an air texture excellent in stretchability and melancholy tone expression is provided, It provides touch feeling, stretch characteristics, melange tone, air texture that is lightweight and functional, and provides fabrics that can be used as outdoors for windproof, down-proof, and mountain climbing.
However, in the above-mentioned prior art, it has been succeeded in making the weathering and lightening by providing the three-ply air texture yarn, and thus it provides the fabric which can be used as outdoorware such as windproof, down-proof, and mountain climbing clothes, and is used for men's and women's formal pants and casual clothes There is a limitation in that it is impossible to impart a warm and natural touch like WOOL.
Therefore, according to the present invention, it is possible to provide a nylon-polyester-polyurethane mixed yarn excellent in elasticity by using a polyurethane elastic yarn as a core and having a melange effect after dyeing, It is a technical object to provide a fabric which can be applied to garments such as men's and women's formal pants, casual clothes, golf pants, lightweight jeans, and uniforms, which are excellent in stretchability and excellent in wearing comfort.
Therefore, according to the present invention, nylon filaments having a fineness of 70 to 140 d / 68 filaments and polyester DTY filaments having a fineness of 75 to 150 d / 72 filaments are fed to the same six pairs of feed rollers, 10 to 11%, and an overfeed rate of 22 to 24% of the fourth feed roller. Air texture is performed at air pressure of 8 to 9 kg / cm 2 from the air texture nozzle, and then heat treatment is performed at 160 to 170 캜. m / min to produce an air-textured yarn;
Polyurethane elastic yarn of 40 to 60 d is stretched 3 to 4 times and used as a core yarn, and the air-textured yarn is used as a cover yarn to cover the yarn with TM 600 to 800 to produce a nylon-polyester-polyurethane mixed yarn Wherein the nylon-polyester-polyurethane blend yarn is produced by a method comprising the steps of:
Hereinafter, the present invention will be described in more detail.
The present invention relates to a nylon-polyester-polyurethane blended yarn for providing a fabric having excellent elasticity by using a polyurethane elastic yarn as a core and having a melange effect after dyeing by mixing nylon and polyester yarn, ≪ / RTI >
The manufacturing method of the nylon-polyester-polyurethane mixed yarn of the present invention is roughly divided into two steps, namely an ATY (air texturing) process and a covering process.
First, in the ATY process, a nylon filament having a fineness of 70 to 140 d / 68 filaments and a polyester DTY having a fineness of 75 to 150 d / 72 filaments are supplied to the same six pairs of feed rollers, The feed rate of the rollers is 10 to 11% and the feed rate of the fourth feed roller is 22 to 24%. The air texture is subjected to air texture at an air pressure of 8 to 9 kg / cm 2 and then heat treated at 160 to 170 ° C. , And a wind speed of 70 to 80 m / min to produce an air-textured yarn.
In the present invention, when the nylon filament and the polyester DTY yarn are fed to the air texturing apparatus, the feed roller is composed of six pairs of feed rollers different from those of the conventional four pairs, and the homogeneity of the fineness is excellent desirable.
Especially, the over feed rate should be controlled well. It is preferable that the over feed rate of the third feed roller is 10 to 11% and the over feed rate of the fourth feed roller is 22 to 24%. If the over feed rate of the third feed roller is less than 10%, the fineness of the ATY yarn becomes low, and when the over feed rate exceeds 11%, the problem of LOOP phenomenon may occur. If the over feed rate of the fourth feed roller is less than 22%, the fineness of the ATY yarn is lowered. If the over feed rate is more than 24%, the yarn surface may become rough after ATY.
After air texture at air pressure nozzle of 8 ~ 9㎏ / ㎠, it is heat treated at 160 ~ 170 ℃. After heat treatment, ATY company maintains thermal stability and wrinkles of branch tube due to residual water content of yarn during WINDING. . After the heat treatment, it is wound at a speed of 70 to 80 m / min to produce an air-textured yarn as an intermediate product of the mixed yarn of the present invention.
Next, as a covering step of the second step, a polyurethane elastic yarn of 40 to 60 d is stretched by 3 to 4 times and used as a core yarn, and the prepared air texture yarn is used as a cover yarn to cover TM 600 to 800, Thereby producing a polyester-polyurethane mixed yarn.
The polyurethane elastic yarn of 40 to 60 d used as core yarn is stretched 3 to 4 times. When stretching to less than 3 times, the stretchability of the covering yarn is too large and the stretchability of the fabric is too large, The stretchability of the covering yarn is excessively high and the stretchability of the fabric may not be obtained.
The nylon-polyester-polyurethane mixed yarn has a weight ratio of nylon: polyester: polyurethane of 57 to 65: 30 to 33: 5 to 10, and melanin in the medium color which is used as a fabric for main season F / The effect can be most variously exhibited.
In the present invention, the polyurethane elastic yarn is 40 to 60 d in the present invention, and the nylon filament and the polyester DTY yarn having a fineness of 75 to 150 d / A nylon-polyester-polyurethane mixed yarn is provided in which the texture yarn becomes a cover yarn and is covered with TM 600 ~ 800, and has a melange effect after dyeing, and also has excellent elasticity by using a polyurethane elastic yarn as a core yarn.
Therefore, according to the present invention, it is possible to use a polyurethane elastic yarn as a core to provide a nylon-polyester-polyurethane mixed yarn having excellent elasticity by using a melange effect after dyeing, It can be applied to clothes such as men's and women's suits, casual clothes, golf pants and lightweight jeans and school uniforms that can impart the same warm and natural touch. In particular, nylon and polyester composite yarn, which can be washed with general water, has an advantage of being easy to manage after wearing clothes.
