Description

Filament spinning and winding combined process for Gotelon
Technical Field
The invention relates to the technical field of chemical fiber production processes, in particular to a spinning and winding combined process for a filament of a Golgin fiber.
Background
The Z-shaped broken line type structure of the polymer molecular chain enables the fiber to have the advantages of being softer in hand feeling, easier to care and dye, good in color fastness to washing and ultraviolet resistance, acid-resistant and alkali-resistant, not easy to age and good in size stability of the fabric compared with polyester and nylon. The advantages enable the high Teflon fabric to have wide application prospect in the fields of novel clothes and home textiles. The high-grade costume, the swimsuit, the close-fitting costume, the sportswear and other elastic costumes can be developed by utilizing the high-Terylene fiber, and the manufactured costume has the advantages of comfortable wearing, soft touch, easy washing, quick drying and no ironing, and meets the requirement of fast pace of life of people.
However, since the technology of foreign companies which master the technology of producing the filaments of the gaoton is blocked, a few domestic manufacturers are in respective closed exploratory trial production stages at present. According to the knowledge of the applicant to the industry, the common practice of part of domestic manufacturers is as follows: the technology for manufacturing the fully drawn PET (polyester) filament is improved on the basis of the technology for manufacturing the PET filament. The manufacturing process sequentially comprises the following steps: the method comprises the steps of preparing a material for the Teflon slice raw material, melting the prepared material for the Teflon slice raw material, spinning a Teflon melt, cooling and bundling a plurality of Teflon nascent fibers and drawing and winding the Teflon tows, wherein all the steps are combined and continuously completed in sequence. Wherein, the drafting and winding process of the Teflon tows comprises the following steps: and fully drafting the Teflon tow. In the step, the high-temperature polyethylene filament bundle is heated at low temperature by a pair of low-temperature hot rollers (consisting of two low-temperature hot rollers), and then is drawn by a pair of high-temperature hot rollers (consisting of two high-temperature hot rollers) or a pair of high-temperature single rollers (consisting of one high-temperature hot roller and one filament separating cold roller), and the drawn high-temperature polyethylene filament bundle (namely the high-temperature polyethylene filament) is subjected to high-temperature heat setting. The glass transition temperature of the Hilon tows is low, so that only one low-temperature heating roller is needed for heating, obviously, for spinning the Hilon filaments, a pair of low-temperature heating rollers is used for heating the Hilon tows at low temperature, the heating rollers are redundant, equipment engineering configuration is wasted (for example, the redundant heating rollers need to rotate, the driving power and the equipment unit price of the heating rollers are far larger than those of the splitting rollers, the heating rollers also need oil cooling pipelines for bearing cooling and other engineering configurations), consumption is large, economic benefit is affected, and equipment production capacity cannot meet market requirements. And because the Teflon tows have special Z-shaped macromolecular structures, the Teflon tows generate larger drafting stress in the drafting system after being drafted, and the drafting stress in the Teflon tows can be effectively eliminated by heating and shaping at high temperature for a long time. However, the foregoing high temperature heat setting of the filament bundle is performed only by a pair of high temperature hot rolls or a pair of high temperature single rolls, because the pair of high temperature hot rolls is limited by the effective length of the high temperature hot rolls, the number of turns of the filament bundle wound around the pair of high temperature hot rolls is limited, and therefore, it is difficult to extend the heat setting time of the filament bundle (i.e., the time required for the filament bundle to pass from the pair of high temperature hot rolls to the filament bundle leaving the pair of high temperature hot rolls). Similarly, the pair of high temperature single rollers is limited in effective length by the high temperature hot rollers, so that the number of turns of the filament bundle wound around the pair of high temperature single rollers is limited, and thus it is difficult to extend the heat-setting time of the filament bundle (i.e., the time required for the filament bundle to pass from the pair of high temperature single rollers to the exit of the filament bundle from the pair of high temperature single rollers). Therefore, the heat setting of the Teflon tows by only one pair of high-temperature hot rollers or only one pair of high-temperature single rollers is difficult to effectively eliminate the drafting stress in the tows, so that the Teflon filaments are easy to relax and retract along the axial direction in the winding process, the cakes are badly formed, the unwinding is difficult, and the high-quality filaments are difficult to produce.
