Abstract

The invention relates to the technical field of textiles, and discloses a preparation method of a flame retardant viscose fiber / alginate fiber blended fabric. The preparation method comprises the following steps: putting viscose fiber and alginate fiber into a baking oven for drying treatment, and then blending cotton fiber and alginate fiber according to a blending ratio of 1:(2-5) to obtain blended yarn; putting the blended yarn into a steam box for steam treatment, taking out the blended yarn, immersing the blended yarn into a phosphorus based flame retardant for ultrasonic oscillation treatment, putting into a vacuum drying box for drying to obtain dried blended yarn; putting the dried blended yarn into a circular weft knitting machine for weaving, thus obtaining the flame retardant blended fabric. According to the preparation method disclosed by the invention, the yarn is fluffed out through steam to enable the flame retardant to enter the yarn, and the obtained viscose fiber / alginate fiber blended fabric is relatively good in flame retarding effect.

Description

technical field [0001] The invention relates to the textile field, in particular to a method for preparing a flame-retardant viscose fiber / seaweed fiber blended fabric. Background technique [0002] Viscose fiber is made of alkali cellulose by alkalization of plant cellulose, and then reacted with carbon disulfide to form cellulose xanthate, which is dissolved in lye to obtain a viscous solution, and then the viscous solution is wet-spun and a series of processing steps. Viscose fiber has good hygroscopicity, smooth and cool, breathable, antistatic, anti-ultraviolet, colorful, good dyeing and so on; seaweed fiber is a kind of man-made fiber, which refers to some brown algae plants from the ocean. The main value of the fiber made from the alginic acid extracted from seaweed is the seaweed component, which can effectively improve the hygroscopicity, and can exert the hygroscopicity through contact with the skin, actively release the seaweed component, and make the wearer's sk...
