Embodiment 1

[0026] At room temperature, the ultrasonic power is 50% to pretreat the fabric for 10 minutes, and then bleach after washing. The bleaching process is: the amount of hydrogen peroxide is 5g / L; the amount of sodium hydroxide is 5g / L; the amount of EDTA is 0.5g / L, Na 2 SiO 3 The dosage is 0.5g / L, the dosage of penetrant JFC is 0.5g / L, and treated at a temperature of 70°C and pH=11 for 20 minutes; then transferred to an ultrasonic instrument at 70°C with a power of 30%, continued to bleach for 10 minutes, and washed with water (hot water first, then Wash in cold water (hot water temperature is 60°C, cold water temperature is 25°C), spin dry, and dry at 15°C. The whiteness of the treated fabric can reach 68, and the strength loss is less than 5%.

Embodiment 2

[0028] At room temperature, the ultrasonic power is 50% to pretreat the fabric for 10 minutes, and then bleach after washing. The bleaching process is: the amount of hydrogen peroxide is 5g / L; the amount of sodium hydroxide is 5g / L; the amount of EDTA is 0.5g / L, Na 2 SiO 3 The dosage is 0.5g / L, the dosage of penetrant JFC is 0.5g / L, and the temperature is 80°C, pH = 11 for 20min; then transfer to an ultrasonic instrument at 80°C with a power of 50%, continue to bleach for 10min and then wash with water (hot water first, then Wash in cold water (hot water temperature is 60°C, cold water temperature is 25°C), spin dry, and dry at 30°C. The whiteness of the treated fabric can reach 71, and the strength loss is less than 6%.

Embodiment 3

[0030] At room temperature, the ultrasonic power is 50% to pretreat the fabric for 10 minutes, and then bleach after washing. The bleaching process is: the amount of hydrogen peroxide is 5g / L; the amount of sodium hydroxide is 5g / L; the amount of EDTA is 0.5g / L, Na 2 SiO 3 The dosage is 0.5g / L, the dosage of penetrant JFC is 0.5g / L, and the temperature is 90°C, pH=11 for 20min; then transfer to the ultrasonic instrument at 90°C, the power is 50%, continue to bleach for 10min and then wash with water (hot water first, then Wash in cold water (hot water temperature is 60°C, cold water temperature is 25°C), spin dry, and dry at 30°C. The whiteness of the treated fabric can reach 77, and the strength loss is less than 7%.

Abstract

The invention relates to a bleaching method of a mudar floss fabric with low carbon damage. The bleaching method comprises the following steps of: carrying out ultrasonic processing, water washing and spin-drying on the mudar floss fabric at 10-50 DEG C, then putting the processed fabric in a bleaching bath, and carrying out bleaching processing on the fabric at 60-90 DEG C for 5-20 minutes; and transferring the mudar floss fabric and a bleaching solution into an ultrasonic instrument at 60-90 DEG C, continuously bleaching, and then carrying out water washing, spin-drying and drying to obtain the bleached mudar floss fabric. According to the bleaching method disclosed by the invention, the process is simple, the cost is low, the industrial production can be realized easily, the bleaching effect on mudar floss is good, and no additional equipment is required; the problem that existing bleaching reagents such as sodium hydrosulfite and formamidinesulfinic acid (FAS) pollute the environment is solved; in the whole process, no environmental pollution exists; the bleaching method is low-carbon and environment-friendly and has favorable development prospect and economic value.

Description

technical field [0001] The invention belongs to the field of bleaching of fiber fabrics, in particular to a low-carbon bleaching method for squash fiber fabrics. Background technique [0002] With the continuous enhancement of people's demand for advocating nature, returning to nature and environmental protection awareness, green textiles are increasingly favored by people. In recent years, a large number of new environmentally friendly fibers have emerged, such as modal, soybean protein fiber, chitin fiber and so on. As a new type of natural wild, healthy, fashionable, green and environmentally friendly ecological textile fiber, croissant melon fiber has its unique natural characteristics: the fiber is light and soft, with a crystal-like luster; the thin-walled structure of the large and medium cavity makes it resemble kapok Similarly, it has the characteristics of strong pressure resistance, warmth, sound insulation, and good moisture absorption and dehumidification; anti...
