Problems solved by technology

[0003] With the advancement of science and technology, the utilization of cotton stalks has been paid more and more attention by people, but at present the development of cotton stalks is mainly to use cotton stalk fibers to make paper, but there is no way to use cotton stalks to produce textile fibers
[0004] In addition, the raw materials, intermediates, or dyes of synthetic dyes currently used in textiles are carcinogenic substances, which not only seriously pollute the environment, but also harm the wearers and producers, and are banned. The main source of synthetic dyes that are not currently banned It is oil, and the world's resources are becoming increasingly scarce, which does not meet the requirements of sustainable development

Embodiment 1

[0019] As shown in Figure 1: 1, the cotton stalk gets the leather tie and puts into the pot (also can dye the cotton yarn wrapped in the same bath) and compact it. 2. Peeled cotton straw replaces coal (saving national resources) for boiler use, heating and gas supply. 3. The ashes after the cotton stalks are burnt are collected in a dissolver, and water is added to make ash juice with a concentration of 15%. 4. Pour the prepared ash juice into the cooking pot. The weight ratio of ash juice and cotton lint is 1:20. The heating and scouring temperature is 95°C-100°C for 1 hour. The cooking liquid is discharged into the dyeing vat, and the cloth, Dyed yarn ready to use. 5. Take out the boiled cotton skin and put it into a warm water pool to wash, decontaminate and dehydrate. 6. Repeat 1, 4, and 5 two to three times on the dehydrated cotton lint, and the original brown cotton lint fiber can be obtained (if bleaching is required, add ash juice and hydrogen peroxide to the pot and...

Embodiment 2

[0021] As shown in Figure 1: 1, the cotton stalk gets the leather tie and puts into the pot (also can dye the cotton yarn wrapped in the same bath) and compact it. 2. Peeled cotton straw replaces coal (saving national resources) for boiler use, heating and gas supply. 3. The ashes after the cotton stalks are burnt are collected in a dissolver, and water is added to make ash juice with a concentration of 15%. 4. Pour the prepared ash juice into the cooking pot, the weight ratio of ash juice and cotton lint is 1:23, heat and cook at a temperature of 95°C-100°C for 2 hours, drain the cooking liquid into the dyeing vat, dye the cloth, Dyed yarn ready to use. 5. Take out the boiled cotton skin and put it into a warm water pool to wash, decontaminate and dehydrate. 6. Repeat 1, 4, and 5 two to three times on the dehydrated cotton lint, and the original brown cotton lint fiber can be obtained (if bleaching is required, add ash juice and hydrogen peroxide to the pot and boil for 2 h...

Embodiment 3

[0023] As shown in Figure 1: 1, the cotton stalk gets the leather tie and puts into the pot (also can dye the cotton yarn wrapped in the same bath) and compact it. 2. Peeled cotton straw replaces coal (saving national resources) for boiler use, heating and gas supply. 3. The ashes after the cotton stalks are burnt are collected in a dissolver, and water is added to make ash juice with a concentration of 15%. 4. Pour the prepared ash juice into the cooking pot. The weight ratio of the ash juice and the cotton skin is 1:25. The heating and scouring temperature is 95°C-100°C for 3 hours. The cooking liquid is discharged into the dyeing vat, and the cloth, Dyed yarn ready to use. 5. Take out the boiled cotton skin and put it into a warm water pool to wash, decontaminate and dehydrate. 6. Repeat 1, 4, and 5 two to three times on the dehydrated cotton lint, and the original brown cotton lint fiber can be obtained (if bleaching is required, add ash juice and hydrogen peroxide to th...

Abstract

The process of extracting cotton bast fiber and vegetable dyeing agent from cotton stalk includes the following steps: tying cotton stalk rind and setting in pot, burning the rinded cotton stalk to provide heat, collecting cotton stalk burning ash and mixing with water to obtain vegetable dyeing agent; washing the boiled cotton stalk rind, dewatering to obtain brown raw cotton stalk rind fiber, drying, oiling, beating, cutting, opening and combing to obtain cotton stalk rind fiber product. The process is environment friendly.

Description

technical field [0001] The invention relates to a method for preparing cotton lint fiber for textile use and a dyeing mordant, in particular to a method for preparing cotton lint fiber and a dyeing mordant by utilizing cotton stalks. Background technique [0002] Cotton straw fiber is composed of bast and stem. The fiber in the bast outside the stem is as high as about 70%. In my country, cotton straw resources are particularly abundant, but in cotton-producing areas, cotton straw is mainly used as fuel. , and cotton fiber is basically made of cotton. [0003] Along with the progress of science and technology, the utilization of cotton stalk is paid more and more attention to by people, but the exploitation of cotton stalk is mainly to come papermaking with cotton stalk fiber at present, but there is no method to utilize cotton stalk to produce textile fiber. [0004] In addition, the raw materials, intermediates, or dyes of synthetic dyes currently used in textiles are carc...
