Problems solved by technology

But it has poor hand feel, poor dyeability, and high cost
[0005] In the Chinese patent application CN1099823A, complexes of inorganic substances are used, such as sodium bisulfite, sodium thiosulfate, ammonium vanadate, copper sulfate, etc., and non-polymer organic compounds, such as alkyl quaternary ammonium chlorides, alkylamide halogenated Treat fabrics with antistatic effects, such as finishing treatment, the fabrics treated in this way have good antistatic effects in the early stage of use, but this kind of fabrics are not resistant to washing, and after many times After washing, its antistatic effect gradually decreases or even disappears
This type of fabric is relatively expensive

Embodiment 1

[0030] Synthesize the sheath-core composite fiber with the following ratio: the mass ratio of dyeable polyester / cotton fiber is 70 / 30.

[0031] Two screws are used to control their respective temperatures to melt the high-temperature and high-pressure cationic dyeable polyester (CDP) (A) and cotton fiber that form the sheath-core respectively, and transport them to the spinning box through their respective melt pipelines. Then the melt is sent to the sheath-core composite spinning assembly quantitatively by the metering pump, extruded, cooled, oiled, and wound to obtain the raw silk of the skin-core composite fiber, and the raw silk is stretched After shaping, the finished sheath-core fiber can be obtained. The spinning temperature is 255°C, the winding speed can be adjusted within the range of 2000m / min, the stretching temperature is 90°C, the setting temperature is 160°C, and the stretching ratio is 2.0 times.

Abstract

The invention provides an antistatic, moisture-regaining and dyeable core pattern complex fiber and fabric made by the same. The core pattern complex fiber comprises a leather layer and a core layer, wherein the mass ratio of the leather layer to the core layer is 90 / 10 to 10 / 90; the core layer is made of polyhydroxy fibre or muti-carboxylic fibre with good hygroscopicity, dyeability and anti-static function; the leather layer is melt-spinnable superpolymer; and the complex fiber has various functions of good mechanical strength, hygroscopicity, anti-static function, dyeability and the like. The fabric made by combining the core pattern complex fiber with photocatalyst coating has the advantages that the fabric is antimicrobial and is disinfected; organic pollutants such as formaldehyde can be effectively removed; and the sustainability and the safety are high.

Description

technical field [0001] The invention relates to a sheath-core composite fiber, in particular to an antistatic, moisture-absorbing and dyeable sheath-core composite fiber Background technique [0002] During the processing and use of chemical fiber textiles, polyamide fibers will generate electrification when they are in contact with each other or with other objects. If the charge continues to accumulate and cannot be eliminated, it will cause various static phenomena. Static electricity makes it difficult to process polyamide textiles. Dust is easily absorbed during product use, and electric sparks generated by static electricity can cause explosions and fires. Therefore, conductive and antistatic fibers, as a high-tech, high-value-added polymer fiber material, have very important and extensive demands in civil, industrial, decorative and military applications. [0003] Commonly used antistatic methods are: (1) pure conductive polymer fiber, which has good antistatic effect...
