Embodiment 1
[0038] Embodiment 1 provides a kind of processing method of PBT polyester fiber for sweater, it is characterized in that, comprises the steps:
[0039] Step S1, raw material configuration: the prepared raw materials are transported, crystallized and dried, mixed according to weight parts, and then stirred and mixed at a speed of 800 rpm for 20 minutes to make a mixture;
[0040] Step S2, screw extrusion: adding the mixture prepared in step S1 into a twin-screw extruder, melt extruding, and granulating to obtain spinning pellets;
[0041] Step S3, spinning: the spinning pellets produced in step S2 are melt-spun through polyester filament spinning equipment, and then spun through a spinneret with one plate and three cakes, and finally wound up by a winding head. Winding to obtain PBT polyester fiber for woolen sweaters.
[0042] The preparation raw materials described in step S1 are made from the following components in parts by weight: 80 parts of spinning grade PBT resin, 2 p...
Embodiment 2
[0049] Embodiment 2 provides a processing method of PBT polyester fiber for woolen sweaters, which is basically the same as in Embodiment 1, except that the preparation raw materials described in step S1 are made of the following components in parts by weight: Composition: 83 parts of spinning grade PBT resin, 3 parts of pumice powder, 0.7 parts of N,N'-bis(2-hydroxyethyl)-N,N'-bis(trimethoxysilylpropyl)ethylenediamine, terminal 3 parts of hydroxyl hyperbranched polyester.
Embodiment 3
[0051] Embodiment 3 provides a processing method of PBT polyester fiber for woolen sweaters, which is basically the same as that of Embodiment 1, except that the preparation raw materials described in step S1 are made of the following components in parts by weight: Ingredients: 85 parts of spinning grade PBT resin, 3.5 parts of pumice powder, 0.8 parts of N, N'-bis(2-hydroxyethyl)-N,N'-bis(trimethoxysilylpropyl)ethylenediamine, terminal 3.5 parts of hydroxyl hyperbranched polyester.

Abstract
The invention discloses a processing method of PBT (polybutylene terephthalate) polyester fiber for woolen sweaters. The processing method is characterized by comprising the following steps: S1, preparing raw materials; S2, carrying out screw extrusion; step S3, carrying out spinning. The invention further discloses the PBT polyester fiber for woolen sweaters, which is processed according to the processing method of the PBT polyester fiber for woolen sweaters. The processing method of the PBT polyester fiber for woolen sweaters adopts a processing mode of one plate with three cakes (namely onespinneret plate with three paths of filaments), is simple and easy to implement, convenient to operate and control, high in processing efficiency and yield, suitable for large-scale production, capable of effectively achieving the purposes of improving productivity and saving energy and stable in production. The prepared PBT polyester fiber for woolen sweaters is good in comprehensive performance, long in service life and good in wearing comfort.
Description
technical field [0001] The invention belongs to the technical field of textile fiber processing, and in particular relates to a processing method of PBT polyester fiber for sweaters. Background technique [0002] In recent years, with the improvement of people's living standards, the consumer demand for home textiles and clothing has continued to expand. With the acceleration of urbanization and the improvement of consumption levels, the market capacity of home textiles and clothing will further expand. The types of fabrics currently on the market Many, with the passage of time, the market needs new, multi-fancy, functional fabrics to meet the needs of high-consumption groups. [0003] PBT fiber is the abbreviation of polybutylene terephthalate fiber, which is a linear polycondensation of high-purity terephthalic acid (PTA) or dimethyl terephthalate (DMT) and 1,4-butanediol after esterification. Polymer, a fiber obtained by melt spinning, is a kind of polyester fiber. This...
