Description

High-comfort fabric and processing technology thereof

Technical field

The invention patent relates to the field of textile technology, in particular to a high-comfort fabric and its processing technology.

Background technique

With the improvement of people's living standards, people's requirements for the comfort and insulation performance of clothes are becoming higher and higher. At present, the underwear on the market generally uses ordinary cotton or copper ammonia type or fiber blended fabrics, but the fat and moisture produced by the human body's metabolism have been emitting moisture through the epidermis. Cotton fabrics, because of the fineness of cotton fibers, have natural curls, and have a cavity in the cross section, so they have good warmth and are more comfortable after wearing, but after a period of time, the human body's metabolism will be more sticky, especially easier. Sweating people, the moisture generated by the human body is more difficult to volatilize, especially in winter, people feel colder and colder, and ordinary cotton is easy to shrink, easy to wrinkle, and the appearance is not very stiff and beautiful. Fiber-blended fabrics have defects of high light points, which can cause skin dryness, frictional static electricity, pilling, suffocation or poor air permeability, poor water absorption, easy threading during washing, and inferiority to cotton when made into clothing. The fabric has the advantages of cheap price, good warmth, breathability, and lightness; but chemical fiber friction easily generates static electricity, so it will adsorb a lot of dust and dander inside over time. In addition, the more the number of holes, the more rough the fiber , The worse the fit.

In the prior art, two-layer weaving is used, and different raw materials are used for the inner and outer layers, but it is reflected in the thicker fabric, which is difficult to meet the modern and modern people who like to wear thin and light.

Summary of the invention

Object of the invention: The object of the present invention is to provide a highly comfortable fabric and its processing technology.

The technical scheme adopted by the present invention is a high-comfort fabric and its processing technology, which are composed of the following raw materials in the following mass percentages: polyester 33 ~ 35%, copper ammonia fiber 55 ~ 60%, spandex 7 ~ 9%, the polyester Blended with spandex as the inner layer of high comfort fabric and its processing technology, blended with copper spandex fiber and spandex as the surface layer of high comfort fabric and its processing technology.

Preferably, the polyester polyester is a profiled polyester, the strength of the profiled polyester is 3.6-4.0 cN / dtex, and the boiling water shrinkage is 4%.

Preferably, the fineness of the spandex fiber is 21 to 23 dtex.

As mentioned above, a high-comfortable fabric processing technology firstly alternately arranges weft yarns with a blend of copper-spandex fibers and spandex and a blend of polyester filaments and spandex, and the feeding length of each yarn is: copper-spun ammonia fiber 280 ～ 320mm / 100N, polyester 270 ～ 310mm / 100N, spandex is 110 ～ 130mm / 100N, and then single-sided weaving method is used to weave all of them into a flat structure. Spandex is added by a small pulley at the press pin to ensure that spandex is in the cloth. All sides are lined with copper ammonia yarn and polyester. The underside is not exposed. Different yarn feeding methods are used for weaving, then dyeing and finishing. After being woven with a wide open-knit single-sided woven fabric, it is directly rolled up. The roll is naturally retracted. Under the heat setting of 190 ° C for 1 minute, the spandex is kept in a basically stable state, and then the dyeing tank is processed by a two-stage dyeing process in stages. The polyester is dyed at 130 ° C under high temperature and pressure. During the dyeing of copper ammonia, during this period, due to the reduction of the intermolecular stress at high temperature of 130 ° C, the polyester produced a vertical shrinkage. After testing at 130 ° C, the shrinkage of polyester is 4%, but copper ammonia fiber does not have this. Heat shrinkage properties, so that after high temperature to shrink the fabric inner layer of polyester, cuprammonium the fabric surface.

Preferably, the mass ratio of the spandex to the copper spandex fiber is 1: 18-20, and the mass ratio of the polyester to spandex is 1: 8-10.

Preferably, the weft yarns are arranged as a copper ammonia and a polyester interlaced.

Beneficial effect: Compared with the prior art, the fabric disclosed in the present invention is light, comfortable, soft and warm. Due to the difference in shrinkage properties of the spandex and raw materials added during knitting, different raw materials are in different positions, and the polyester with high moisture permeability is Shrink to the inner layer of the fabric, copper ammonia fiber is on the outer layer of the fabric, and the moisture of the inner fabric leads to the outer layer of the fabric to keep the inner layer dry. At the same time, the exported moisture is fully utilized, because the grooves of the polyester guide the moisture to The surface of the fabric, and the copper ammonia on the surface has a high moisture modulus, which is particularly easy to absorb moisture, which makes the fabric more comfortable to wear. The copper ammonia fiber has a good moisture absorption and dehumidification effect, and has a good antistatic effect. Because the moisture emitted by the human body is guided by moisture and absorbed by copper ammonia, it is dry, which can make the human body feel warmer.

detailed description

The technical content of the present invention is described in detail below with reference to specific embodiments:

The invention discloses a high-comfort fabric and a processing technology thereof, which are characterized by being composed of the following raw materials in mass percentages: polyester 33 to 35%, copper ammonia fiber 55 to 60%, and spandex 7 to 9%. The blend of polyester and spandex is used as the inner layer of high comfort fabric and its processing technology, and the blend of copper spandex and spandex is used as the surface layer of high comfort fabric and its processing technology.

The polyester polyester is a profiled polyester, the strength of the profiled polyester is 3.6 to 4.0 cN / dtex, the boiling water shrinkage is 4%, and the spandex fiber has a fineness of 21 to 23 dtex.

A high-comfortable fabric processing process. First, a blend of copper-spandex fibers and spandex and a blend of polyester filaments and spandex are alternately arranged on each weft. The feeding length of each yarn is: copper-spandex fiber 280-320mm / 100N, polyester 270 ～ 310mm / 100N, spandex is 110 ～ 130mm / 100N, and then single-sided weaving is used, all loops are woven into a flat structure. Spandex is added by a small pulley at the press pin to ensure that the spandex is fully lined on the cloth surface. The underside of copper ammonia yarn and polyester is not exposed. Different yarn feeding methods are used for weaving, then dyeing and finishing. After being knitted by a wide open knit single-sided woven fabric, it is directly rolled. After unwinding in the dyeing and finishing factory, it naturally retracts. Under the heat setting of 190 ° C for 1 minute, the spandex is in a basically stable state, and then the dyeing tank is processed by a two-stage dyeing process. The polyester is dyed at 130 ° C under high temperature and pressure, and the copper ammonia is heated at 60 ° C under normal temperature and pressure. Dyeing, due to the reduction of internal molecular stress at 130 ° C due to the reduction of internal molecular stress in polyester during this period, the shrinkage of polyester was tested at 130 ° C, and the shrinkage rate of polyester was 4%, but copper ammonia fibers did not have this heat shrinkage performance. In this way, after high temperature, the polyester shrinks to the inner layer of the fabric, and the copper ammonia fiber is on the surface layer of the fabric.

The mass ratio of the spandex and copper spandex fibers is 1: 18-20, the mass ratio of polyester and spandex is 1: 8-10, and the weft yarns are arranged as a copper spandex and a polyester interlaced.

The above is only a preferred embodiment of the present invention, and it should be pointed out that for those of ordinary skill in the art, without departing from the principles of the present invention, several improvements and retouches can be made. These improvements and retouches also It should be regarded as the protection scope of the present invention.
