Problems solved by technology

[0002] Cotton, an annual herb plant, the fruit is like a peach, and there are white fibers and dark brown seeds inside. The fibers are used for weaving and quilts. Various cotton-type fabrics made of cotton refer to cotton yarn or cotton and cotton-type chemical fiber blends. The fabric made of yarn is one of the main fiber raw materials for spring and summer clothes; traditional interwoven cotton is directly made of cotton for weaving, and a single cotton fiber needs to be added with a large amount of chemical agents when weaving, which will not only pollute the environment It is beneficial to the user's health, and at the same time, the fabric made of single cotton fiber is poor in workmanship, low in density, low in color fastness, and prone to color fading; in view of these defects, it is necessary to design a cotton interwoven fabric and processing method based on polylactic acid of

Abstract

The invention discloses a polylactic acid based cotton interwoven fabric and a processing method thereof. The polylactic acid based cotton interwoven fabric is prepared from, by mass, 25-35% of starch, 15-25% of cellulose, 3-8% of calcium carbonate, 10-20% of lime milk, 15-25% of polyester fibers, 5-10% of acetone, 2-5% of a dehydrating agent, 1-3% of a catalyst and 1-3% of a coloring agent according to a formula. A preparation process includes: step one, raw material selection; step two, lactic acid processing; step three, polylactic acid preparation; step four, melt spinning; step five, dyepreparation; step six, interweaving and discharging. The polylactic acid based cotton interwoven fabric and the processing method thereof have advantages that safety and reliability are realized, polylactic acid is obtained by starch fermentation and lactide ring-opening polymerization, lime milk is added for accelerating reaction to obtain polylactic acid with extremely high relative molecular weight, high polylactic acid spinning density, low manufacturing cost and cheapness of raw materials are realized, and production cost is greatly saved.
