Problems solved by technology

When the applicant carried out related experiments, he found that adding emodin directly to the polyester material would easily cause carbonization of organic matter and cause loss, reduce its functionality, and also affect the appearance of the fiber. In the process of further processing, low fiber strength often occurs. , easy to break, etc. In addition, the polyester fiber fabric produced is not resistant to washing, and the fiber wear resistance is poor

Abstract

The invention provides a preparation method of emodin modified polyester filament yarn. The polyester filament yarn contains 0.1-5% of emodin. The preparation method of the polyester filament yarn comprises the steps of preparation of a functional modifier containing emodin, preparation of an emodin composite modifier, mixing and high-speed spinning. According to the emodin modified polyester filament yarn prepared by adopting the method, the adhesion of bacteria can be reduced, and the bacteriostasis rate on staphylococcus aureus, escherichia coli, candida albicans and other bacteria which are easily infected by a human body reaches 95.0-98.5%; the breaking strength of the polyester filament yarn is 6.0-6.2 cN/dtex, the elongation at break is 38.5-40.0%, after the prepared polyester filament yarn fabric is washed for 50 times, the bacteriostasis rate is still 95% or above, the tensile strength retention rate is 98% or above, and the fiber is quite excellent in washing resistance.

Description

technical field [0001] The invention belongs to the technical field of fiber manufacturing, and in particular relates to an emodin-modified polyester filament 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...
