Abstract

The invention provides a silk fiber prepared by modifying plant extracts. According to the silk fiber, the breaking strength is 3.60-3.75 cN / dtex, the elongation at break is 25.6-27.1%, the dye smallspeck rate is less the or equal to 0.001%, the bacteria inhibitive rate against bacillus subtilis is 91.8-92.1%, and the oxygen index after chlorine rinsing for 50 times is 29.0-29.1%. The invention further provides a preparation method of the silk fiber prepared by modifying the plant extracts. The preparation method comprises the steps of pretreatment and secondary treatment of the silk fiber, wherein the pretreatment comprises the steps that ultrasonic cleaning is carried out with deionized water and 1% of dilute hydrochloric acid for 10-15 min, then washing is carried out with ultrapure water, immersing is carried out at room temperature for 10-30 min, temperature is controlled at 25-50 DEG C and standing is carried out for 20-50 h. After the silk fiber is washed for 50 times, the bacteria inhibitive rate against staphylococcus aureus, candida albicans and escherichia coli is almost not reduced; and the flame retardant performance is good, and the oxygen index is reduced little after washing is carried out for 50 times and 100 times.

Description

technical field [0001] The invention belongs to the field of fiber modification, and relates to a silk fiber prepared by modification of plant extracts and a preparation method thereof. Background technique [0002] Viscose fiber belongs to cellulose fiber, which is made of natural fiber (wood fiber, cotton linter) as raw material, and is made into soluble cellulose xanthate through alkalization, aging, sulfonation and other processes, and then dissolved in dilute lye to make Into viscose, made by wet spinning. [0003] The Chinese patent with the application number CN201810118204.3 provides a method for preparing cationic modified viscose fibers. The preparation method includes the preparation of cationic modification solution and cationic modification. It is carried out in the continuous production process of conventional viscose fiber, without increasing equipment investment, it can be realized on the existing production line, and is suitable for large-scale production. ...
