A kind of three-component composite fiber with high resistance to pilling and high wear resistance and preparation method thereof

Abstract

The invention relates to a preparation method of a three-component composite fiber with high fuzzing and pilling resistance and high wear resistance. The method comprises the following steps: drying a slice A, a slice B and a slice C; correspondingly feeding the slices into corresponding screw extruders to smelt and extrude; then transferring into a spinning box body to spin through a spinning assembly; feeding melts of the slice A, the slice B and the slice C into corresponding spinning micropores; forming a smelt on the surface of a spinning plate in a smelt form; slowly cooling and coating with oil to obtain the three-component composite fiber. According to the method, a melt distributing plate is designed in an asymmetric melt running channel form; the spinning micropores in the spinning plate are three-leaf shaped; the micropore corresponding to each component is different in length to diameter ratio; a multi-oiling device is adopted for coating the oil; the fuzzing and pilling resistance level of a fabric prepared through the fiber is up to 5 level, and the wear resistance reaches more than two hundred thousand times; the fabric prepared through the fiber can be widely applied to the fields of middle-level and high-level one-piece trousers, one-piece socks, underwear, sports and leisure fabrics, fitness clothing, school uniforms, battle dress uniforms and training uniforms of army and armed police.

Description

technical field [0001] The invention belongs to the field of spinning, and relates to a three-component composite fiber with high pilling resistance and high wear resistance and a preparation method thereof. Background technique [0002] With the improvement of people's requirements for comfort, functional composite fibers have gradually become the leader in the fiber field, and the application fields have also expanded from traditional hosiery, underwear, sportswear, etc. to emerging fields such as casual wear, high-elastic fashion, and high-end ready-to-wear. , and continue to expand to the field of automotive decoration and medical fields. As the market demand for this kind of comfortable, casual and convenient multi-purpose clothing increases, the research and application of composite fibers are gradually deepening. At present, functional composite yarns and fabrics have occupied a very important position in the world textile industry. [0003] At present, the composit...

Problems solved by technology

[0004] However, spandex requires a lot of investment and the spinning speed is slow, generally 650-750 meters per minute, some are slightly higher, and the investment and installation of 10,000 tons of equipment is about 350-500 million yuan

There are many intermediate processing steps in the production and processing of spandex, such as core spinning, covering yarn and deformation processing, which reduce the production efficiency of composite fiber fabrics. At the same time, there are many post-spinning processing steps in the production and processing of spandex. Increased fabric and garment production costs

In addition, in the past, when spandex was used to produce polyester composite silk fabrics, it often failed due to the high temperature and high pressure dyeing of polyester.
