Take you to learn more about the process flow of polyester flame retardant silk!

I. Overview

Polyester flame retardant wire refers to the use of a series of chemical or physical means, so that polyester fabric can slow down or prevent the burning process when burning. This special processing technology makes the polyester fabric more in line with the safety requirements, and is widely used in home textile, industry, medical and other fields.

The processing technology of polyester flame retardant silk mainly includes spinning, dyeing, finishing and other links, below we will introduce it in detail.

Second, the process flow

1. Spinning

The spinning process of flame retardant polyester yarn is basically the same as that of general polyester yarn. First, the chemical fiber raw materials are processed into roving, and then flame retardants are added by spraying, coating, etc., and finally continue to be processed into textiles.

Step 2 Dye

Dyeing is one of the important links of flame retardant polyester. In the dyeing process, some anti-pressure agents and whitening agents are usually added to enhance the quality of polyester flame retardant fabric.

Step 3 Organize

Finishing is the last process of polyester flame retardant silk, the main purpose is to eliminate traces on the surface of the fabric and improve the gloss. Finishing methods are usually calender finishing and fuzz finishing. In the finishing process, a certain amount of softener and antibacterial agent is often added to increase the comfort and hygiene of polyester flame retardant fabric.Iii. Summary

The above is the process flow of polyester flame retardant wire, although the processing process of polyester flame retardant wire is more complicated than ordinary polyester, but because of its superiority in safety performance, it is gradually accepted by people. The application prospect of polyester flame retardant is very broad, it is believed that in the near future, polyester flame retardant silk will become a common material.
