Imitated silk heat treatment processing process

Abstract

Disclosed is an imitated silk heat treatment processing process. Imitated silk is made according to an FDY chip spinning production route. Dry chips are melted and extruded into melt by a screw extruder. The melt is conveyed to all spinning positions through pipelines after impurities in the melt are removed by a pre-filter. The spinning positions quantitatively send the melt to all spinning assemblies by metering pumps. The melt is extruded into injected filaments from spinneret holes of spinneret plates in the spinning assemblies. Continuous injection is carried out around the spinneret plates by tap water guns, the injection amount being controlled to 0.5-2 cubic meters per minute. The injected filaments are then cooled by annular air blowing for solidifying into filament strips, bundled, oiled, drawn for shaping, and then wound into filament cakes by adding networks. The imitated silk heat treatment processing technology avoids the problem of reduction of spinnability caused by easy breaking and hairing in a production process of the imitated silk to the greatest extent, improves the uniformity of raw silk, is beneficial to normal spinning, and improves the full roll rate.

Description

technical field [0001] The invention belongs to the technical field of textiles and specifically designs a heat treatment process for imitation silk. Background technique [0002] Simulated silk is a differentiated fiber that has developed rapidly in recent years. As a high-tech textile raw material in synthetic fibers, it has achieved great results in the field of clothing. It overcomes the disadvantages of easy wrinkle and poor fastness of silk fabrics, and is a high-value-added, high-tech product with broad market prospects and good economic benefits. Ultrafine polyester imitation silk is developing rapidly at present. As a high-tech product, imitation silk not only endows the fabric with excellent wearability, but also faces many problems in the later processing that other synthetic fibers have not encountered. It has the greatest influence on the performance of silk, and heat treatment is a very important part of it. [0003] Although artificial silk has brought good ...

AI Technical Summary

Problems solved by technology

[0004] In view of the background technology, the imitation silk has high requirements on spinning temperature and high temperature control accuracy in the production process, and it is easy to break the end during production, resulting in fuzz, increasing the production difficulty, and affecting the post-processing performance.
