Embodiment 1

[0027] (1) After the cotton fibers are removed from the surface impurities, they are immersed in deionized water, taken out and aired to obtain cotton fibers with a moisture content of 20%, and the moisture-containing cotton fibers are placed in a subzero-10°C environment to freeze to obtain pretreated cotton fibers. fiber.

[0028] (2) Put the pretreated cotton fiber prepared in step (1) into the sarong of the liquid ammonia treatment tank, vacuumize, and process 2 times through intermittent and repeated liquid ammonia treatment, wherein the intermittent and repeated liquid ammonia treatment includes dispensing a sufficient amount of liquid ammonia Immerse the cotton fiber for 10s, drain the ammonia and pump out the ammonia gas, and remove the ammonia by microwave for 3min at a power of 50kW to obtain the cotton fiber treated by liquid freezing.

[0029] (3) the cotton fiber of the liquid freezing treatment that step (2) is prepared is placed in the chitosan treatment liquid ...

Embodiment 2

[0030] (1) After the cotton fibers are removed from the surface impurities, they are immersed in deionized water, taken out and aired to obtain cotton fibers with a moisture content of 60%, and the hydrated cotton fibers are placed in a subzero-20°C environment to freeze to obtain pretreated cotton fibers. fiber.

[0031] (2) Put the pretreated cotton fiber prepared in step (1) into the sarong of the liquid ammonia treatment tank, vacuumize, and process 3 times through intermittent and repeated liquid ammonia treatment, wherein the intermittent and repeated liquid ammonia treatment includes dispensing a sufficient amount of liquid ammonia Immerse the cotton fiber for 20s, drain the ammonia and pump the ammonia gas, and remove the ammonia by microwave at 80kW power for 5min to obtain the cotton fiber treated by liquid freezing.

Abstract

The invention provides a novel modified cotton fiber for infants based on liquid freezing and a preparation process thereof. The novel modified cotton fiber comprises the steps: (1) after surface impurities are removed from the cotton fiber, soaking the cotton fiber in deionized water, taking out and airing the cotton fiber to obtain a water-containing cotton fiber, placing the water-containing cotton fiber in the subzero environment to perform freezing, and obtaining the pretreated cotton fiber; (2) placing the pretreated cotton fiber in a yarn cage of a liquid ammonia treatment tank, performing vacuumizing, and performing intermittent repeated liquid ammonia treatment 2-3 times to obtain the cotton fiber having undergone liquid freezing treatment; (3) placing the cotton fiber having undergone liquid freezing treatment in treating fluid according to the bath ratio of 1:(30-40), performing ultrasonic oscillation, taking the cotton fiber out, performing washing and drying, and obtaining the modified cotton fiber for infants based on liquid freezing. The prepared modified cotton fiber for infants based on liquid freezing first undergoes soaking treatment and then undergoes liquid freezing treatment, so that the surface of the cotton fiber is flat, the anti-wrinkle performance is improved while the water absorption is not affected much, and the antibiosis and health care effects are achieved finally through chitosan treatment.

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...
