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

Embodiment Construction

[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0031] The invention discloses a production method for filament spinning and winding.

[0032] Specific steps are as follows:

[0033] (1) Carrying out the winding process on the high telon tow;

[0034] (2) The step of fully drafting the high-Tron filament bundle; including: passing the first spinning hot roller group composed of a heatable hot roller and an unheated splitting roller to cool the high-Tron filament bundle. Heating, and then passing through the second spinning hot roll group consisting of a heatable hot roll and an unheated splitting roll, drafting the low-temperature heated high-Tron filaments to form high-Tron filaments and Preliminary high-temperature heat setting of high-t...

Abstract

The invention provides a filament spinning, winding and producing method. The method is characterized by comprising the following specific steps that firstly, a Corterra filament tow is wound; secondly, the Corterra filament tow is fully drawn, wherein the Corterra filament tow is subjected to low-temperature heating through a first spinning hot roller set composed of a hot roller capable of beingheated and a separator roller which is not heated, then the Corterra filament tow obtained after low-temperature heating is drawn into Corterra filaments through a second spinning hot roller set composed of a hot roller capable of being heated and a separator roller which is not heated, and the Corterra filaments are subjected to primary high-temperature heat setting; thirdly, the Corterra filaments obtained after primary high-temperature heat setting are subjected to independent high-temperature heat setting through a third spinning hot roller set composed of a hot roller capable of being heated and a separator roller which is not heated, and Corterra fully-drawn filaments are formed.

Description

technical field [0001] The invention relates to the technical field of chemical fiber production technology, in particular to a production method for filament spinning and winding. 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 life of people. [0003] Howev...
