Abstract

The invention discloses a production method and a product of moisture absorption and sweat exhaust fiber of chinlon 6. The method is that dried slices of nylon 6 are put into a screw extruder to form melts of chinlon 6, which are then spun by a spinneret with an irregular section arranged in a spinning box body. After processes of slow cooling, cross air blowing, oiling and following high speed winding, the moisture absorption and sweat exhaust fiber of chinlon 6 is made.

Description

technical field [0001] The invention relates to a production method of nylon 6 filament, in particular to a production method of nylon 6 filament with moisture absorption and perspiration function, and belongs to the technical field of synthetic fibers. The invention also relates to products manufactured by the nylon 6 moisture-absorbing and perspiration-wicking fiber production method. Background technique [0002] With the improvement of living standards, people pay more and more attention to the comfort performance of clothing, and the various high-tech contents of clothing fabrics are also getting higher and higher. The moisture-wicking properties of clothing are an important indicator of comfort. Moisture-absorbing and sweat-wicking fiber refers to the use of the capillary phenomenon produced by the fine grooves on the surface of the fiber to make sweat quickly migrate to the surface of the fabric through wicking, diffusion, transmission, etc. and diverge to achieve th...
