Problems solved by technology

However, the water absorption of brown cotton is very poor, and the wool effect of untreated brown cotton fabric is almost zero. The main reason is that brown cotton has a high content of pectin wax
The color of brown cotton fabric will deepen when it is wet treated. If the fabric surface is not treated, the water absorption will be uneven, which will cause serious color difference
Moreover, brown cotton also has problems such as poor spinnability, unstable pigment, and poor shape stability, which seriously affect the wearing performance and market development of the product.

Embodiment 1

[0039] Put 1% o.w.f refining agent, 1.5% o.w.f sodium tripolyphosphate and 0.3% o.w.f penetrating agent into the stainless steel high-temperature steel cup; then add water to the stainless steel high-temperature steel cup, so that the treatment bath ratio is 1:20; Put the brown cotton fiber into the stainless steel high-temperature steel cup, tighten the cover of the stainless steel high-temperature steel cup; place the stainless steel high-temperature steel cup in the high-temperature small sample machine, and treat it at a temperature of 95°C for 40 minutes; put the treated brown cotton fiber Fully wash three times with hot water at 80°C, then twice with warm water at 60°C, and once with cold water, then wring out and dry at 100°C.

[0040] Take 0.2 g of brown cotton fibers treated with improved water absorption performance for water absorption test, and the time required from contacting the water surface to complete wetting and sinking is 52.85 seconds.

Embodiment 2

[0042] Put 1.6% o.w.f refining agent, 2% o.w.f sodium tripolyphosphate and 0.8% o.w.f penetrating agent into the stainless steel high-temperature steel cup; then add water to the stainless steel high-temperature steel cup, so that the treatment bath ratio is 1:20; Put the brown cotton fiber into the stainless steel high-temperature steel cup, tighten the cover of the stainless steel high-temperature steel cup; place the stainless steel high-temperature steel cup in the high-temperature small sample machine, and treat it at a temperature of 95°C for 40 minutes; put the treated brown cotton fiber Fully wash three times with hot water at 80°C, then twice with warm water at 60°C, and once with cold water, then wring out and dry at 100°C.

[0043] Take 0.2 g of brown cotton fibers treated with improved water absorption performance for water absorption test, and the time required from contacting the water surface to complete wetting and sinking is 48.36 seconds.

Embodiment 3

[0045] Put 2% o.w.f refining agent, 2.5% o.w.f sodium tripolyphosphate and 1.0% o.w.f penetrating agent into the stainless steel high-temperature steel cup; then add water to the stainless steel high-temperature steel cup, so that the treatment bath ratio is 1:20; Put the brown cotton fiber into the stainless steel high-temperature steel cup, tighten the cover of the stainless steel high-temperature steel cup; place the stainless steel high-temperature steel cup in the high-temperature small sample machine, and treat it at a temperature of 95°C for 40 minutes; put the treated brown cotton fiber Fully wash three times with hot water at 80°C, then twice with warm water at 60°C, and once with cold water, then wring out and dry at 100°C.

[0046] Take 0.2 g of brown cotton fibers treated with improved water absorption performance for water absorption test, the time required from contacting the water surface to complete wetting and sinking is 44.69 seconds.

Abstract

The invention relates to the technical field of textile, in particular to a method for improving the water absorption performance of brown cotton fiber. The method comprises the steps of: placing a refining agent, an extraction agent and a penetrating agent into a container; putting brown cotton fiber into the container to perform treatment; and washing and drying the treated brown cotton fiber. The method provided by the invention employs the refining agent, the extraction agent and the penetrating agent to treat the brown cotton fiber, so that the water absorption performance of the brown cotton fiber can be improved, i.e. a good hydrophilic foundation is achieved, thus laying a good foundation for endowing the brown cotton fiber with higher performance.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a method for improving the water absorption performance of brown cotton fibers. Background technique [0002] Colored cotton is a kind of cotton with natural colors. It does not need to be dyed in textile processing, thereby reducing the processing procedures, correspondingly reducing the discharge of sewage and the treatment of sewage, and avoiding the pollution of water resources during processing and the prohibition of dyes. The hazards of the additives to the human body and the damage to the environment reduce energy consumption, thereby reducing production costs. In addition, the content of heavy metal elements in colored cotton is all lower than the environmental protection index, and the content of some heavy metals is even lower than that of white cotton, which shows that colored cotton fully meets the environmental protection requirements. Its textiles can be called "t...
