Problems solved by technology

[0002] Common fabrics in life are generally divided into cotton, linen, silk, woolen cloth, leather, chemical fiber, blended, etc., which are usually used to make fashion, casual wear, underwear, shirts and other clothing. At the same time, the quality of the products produced by different fabrics The disadvantages are also inconsistent. Like cotton fabrics that are generally seen, its advantages are easy to keep warm, close to the body, good warmth retention and air permeability, but at the same time, it also has easy shrinkage, easy wrinkle, poor recovery performance, etc.
[0003] However, no matter what kind of fabric is stored for a long time, especially when it is placed in a humid environment, it will easily become moldy, resulting in loss of fabric, and it needs to be treated with mildew removal, even if the mold is severe. , which directly leads to the fact that the fabric cannot be damaged and cannot be reused. Therefore, we propose a mildew-proof processing method for polylactic acid fiber fabrics

Embodiment 1

[0029] A mildew-proof processing method for polylactic acid fiber cloth, comprising the following steps:

[0030] S1: The production of lactic acid and polylactic acid, select starch-rich corn, wheat, cassava, etc. as raw materials, add biocatalysts to convert starch into glucose and other monosaccharides, and then add pure lactic acid bacteria and calcium carbonate cultivated in wort for fermentation. Boil and sterilize after fermentation, filter after cooling, then recrystallize with hot water, add 50% sulfuric acid to decompose lactic acid and calcium sulfate precipitates, evaporate and concentrate the filtrate under reduced pressure to obtain lactic acid, and then polymerize Preparation of lactic acid;

[0031] Among them, the preparation of polylactic acid adopts direct polycondensation / solid phase polymerization to form high-molecular polylactic acid, and the reaction environment is selected as a closed space, and calcium oxide is used as a dehydrating agent during the r...

Abstract

The invention discloses a mildew-proof processing method of polylactic acid fiber cloth. Through preparation of lactic acid and polylactic acid, spinning forming processing, drying and mildew-proof treatment, the manufacturing process of a fabric is quicker, and the polymerization degree of the polylactic acid is higher; and through soaking of a working solution and spraying of a mildew-proof agent, the mildewproof treatment is carried out for multiple times, so that the obtained fabric has a better mildew-proof effect.

Description

technical field [0001] The invention relates to the field of cloth processing, in particular to a mildew-proof processing method for polylactic acid fiber cloth. Background technique [0002] Common fabrics in life are generally divided into cotton, linen, silk, woolen cloth, leather, chemical fiber, blended, etc., which are usually used to make fashion, casual wear, underwear, shirts and other clothing. At the same time, the quality of the products produced by different fabrics The disadvantages are also inconsistent. Like cotton fabrics that are generally seen, its advantages are easy to keep warm, close to the body, good warmth retention and air permeability, but it also has easy shrinkage, easy wrinkle, and poor recovery performance.
