A kind of polyester filament containing wormwood extract and preparation method thereof

Abstract

The invention provides a preparation method of polyester filament yarns containing wormwood extract. Content of the wormwood extract is 0.1 to 5%. The preparation method of the polyester filament yarns comprises steps of preparation of a function modifier containing the wormwood extract, preparation of plant functional master batches, mixing filtering, high-speed spinning, primary drafting, oilingtreatment, secondary drafting and winding. By the process, a frequency of blocking a spinneret can be greatly reduced, and a spinneret replacement rate of the spinneret is reduced to 12 to 15%; meanwhile, the prepared polyester filament yarns reach an antibacterial rate of 96.0 to 98.5% for bacteria easy to infect by human bodies, such as staphylococcus aureus, escherichia coli, candida albicansand the like; and the finished yarns are uniform in colour and lustre and high in transparency, and obvious carbon black and particle agglomeration phenomenon are invisible to naked eyes.

Description

technical field [0001] The invention belongs to the technical field of spinning, and in particular relates to a polyester filament containing wormwood extract and a preparation method thereof. Background technique [0002] Polyester is the trade name of polyester fiber in my country, and it is an important variety of synthetic fibers. Polyester fiber is called a new generation of synthetic fiber, which has the characteristics of warmth, lightness, breathability, close-fitting, comfort and softness. It has achieved results that are difficult to achieve with other fibers, especially polyester imitation silk knitted fabrics. It not only has the advantages of moisture absorption and breathability of silk, and is comfortable to wear, but also overcomes the shortcomings of silk fabrics such as easy to wrinkle, stick to the body and poor fastness, and endows the fabric with good quality. Excellent extensibility, drapability and breathability, it is an excellent material for making sp...

AI Technical Summary

Problems solved by technology

[0004] (1) The ingredients of the wormwood extract are seriously lost during the preparation process, the antibacterial and insect-proof effect is weakened, and the antibacterial persistence is poor;

[0005] (2) The modifier containing wormwood extract is easy to block holes during spinning, and the spinning efficiency is low;

[0006] (3) The compatibility between wormwood extract and polyester is not good, which affects the dry heat shrinkage rate, breaking strength and elastic elongation of polyester fiber.
