Abstract

The invention provides a modified cotton fiber for infants and young children based on liquid freezing and its preparation process. The specific preparation steps are: (1) remove the surface impurities of the cotton fiber, soak it in deionized water, take it out and dry it to obtain the cotton fiber containing water , the cotton fiber containing water is placed in sub-zero environment to freeze, obtains the cotton fiber of pretreatment; (2) puts the cotton fiber of pretreatment in the sarong of liquid ammonia treatment tank, vacuumizes, through intermittent repeated liquid ammonia treatment 2- 3 times to obtain the cotton fiber treated by liquid freezing; (3) the cotton fiber treated by liquid freezing is placed in the treatment liquid with a bath ratio of 1:30-40, ultrasonically oscillated, taken out, washed and dried, and obtained based on liquid freezing Modified cotton fibers for infants and young children. The modified cotton fiber for infants and young children based on liquid freezing prepared by the present invention is first soaked in water, and then subjected to liquid freezing treatment, so that the surface of the cotton fiber is smooth and the anti-wrinkle performance is improved, but the water absorption is not much affected, and finally it is treated with chitosan Treatment to impart antibacterial health benefits.

Description

Technical field: [0001] The invention belongs to the technical field of textile materials, and in particular relates to a modified cotton fiber for infants based on liquid freezing and a preparation process thereof. Background technique: [0002] As we all know, the infant period is the most delicate and fragile period in a person's life. Although the innovation of modern textile technology has caused great changes in the structure of clothing fabrics, the choice of infant clothing is still based on hygienic and comfortable natural fibers. Mainly, cotton fiber, as one of the four natural fibers cotton, wool, silk, and hemp, has always been favored by people because of its unique and excellent properties such as softness, warmth, and comfort. [0003] Cotton fiber has good softness, warmth, moisture absorption and conductivity, but poor wrinkle resistance, poor durability, easy to mold, and single function, it is difficult to meet the growing consumer demand, and the improvem...
