Efficient spinning and winding production method of chemical fiber filament

Abstract

The invention provides an efficient spinning and winding production method of chemical fiber filament. The method is characterized by comprising the following concrete steps: (1) performing a windingworking procedure on Corterra tows; (2) carrying out full drafting on Corterra long tows, wherein the step comprises: performing low-temperature heating on the Corterra tows through a first spinning heating roller group which consists of a heating roller capable of heating and a splitting roller incapable of heating, then drafting the Corterra tows, which are subjected to low-temperature heating,to form the Corterra long tows through a second spinning heating roller group which consists of a heating roller capable of heating and a splitting roller incapable of heating, and performing preliminary high temperature heat setting on the Corterra long tows; and (3) performing further independent high-temperature heat setting on the Corterra long tows, which are subjected to preliminary high-temperature heat setting, through a third spinning heating roller group, which consists of a heating roller capable of heating and a splitting roller incapable of heating, so as to form Corterra full drafting filament.

Description

technical field [0001] The invention relates to the technical field of chemical fiber production technology, in particular to a high-efficiency spinning and winding production method of chemical fiber filaments. Background technique [0002] The "z" fold line structure of the high telon molecular chain makes the fiber have better advantages than polyester and nylon, that is, it feels softer, easier to care and dye, and has good color fastness to washing and anti-ultraviolet performance , acid and alkali resistance, not easy to aging, good dimensional stability of the fabric. These advantages make Gaotelun fabrics have broad application prospects in the fields of new clothing and home textiles. High-grade clothing and flexible clothing such as swimsuits, tights, and sportswear can be developed by using high-grade fiber. The clothing produced is comfortable to wear, soft to the touch, easy to wash, quick-drying, and non-ironing, which meets the requirements of the fast-paced ...

AI Technical Summary

Problems solved by technology

And the above-mentioned high-temperature heat-setting of the high-temperature hot-roller only through a pair of high-temperature hot rollers or a pair of high-temperature single-rollers, because the pair of high-temperature hot-rollers are limited by the effective length of the high-temperature hot-roller, the high-temperature hot-roller tow is wound The number of turns on this pair of high-temperature hot rollers is limited, so it is difficult to extend the time of heat setting of the high-temperature tow (that is, the time for the tow to leave the pair of high-temperature hot rollers from arriving at the pair of high-temperature hot rollers) travel time)

In the same way, the pair of high-temperature single rollers is limited by the effective length of the high-temperature hot rollers, so that the number of turns of the high-temperature single-roller to be wound on the high-temperature single-roller is limited, so it is difficult to extend the high-temperature tow The time of heat setting (that is, the time required for the tow to travel from arriving at the pair of high-temperature single rollers to leaving the pair of high-temperature single rollers)

It can be seen from this that it is difficult to effectively eliminate the drawing stress inside the tow by only relying on a pair of high-temperature hot rollers or only a pair of high-temperature single rollers to heat-set the high-temperature filament tow, and it is easy to cause high-temperature filaments in the winding process. Loose and shrink along the axial direction, and the yarn cake is too badly formed, it is difficult to unwind, and it is difficult to produce high-quality filament
