Problems solved by technology

[0003] The environmental protection characteristics of natural colored cotton have attracted more and more people's attention, but its poor spinnability, unstable pigment, and poor shape stability have seriously affected the wearability of the product and market development.
At present, the colored cotton that can be processed in the colored cotton market is only brown and green. Among them, the biggest disadvantage of green cotton is that its light fastness is very poor, only 2-3 grades, which seriously reduces the grade of green cotton products.

Embodiment 1

[0059] Adopt one-bath method to process green cotton fiber, as shown in table 1, namely refining agent 2.2% (o.w.f), sodium tripolyphosphate 6% (o.w.f), ferrous ammonium sulfate 0.1-10% (o.w.f) in bath ratio 1: 20. Treat the green cotton at 95°C for 60 minutes, then fully wash it three times with 80°C hot water, once in cold water, wring it out, and dry it at 100°C.

[0060] Table 1

[0061]

[0062] The difference in the amount of ferrous ammonium sulfate can make the green cotton produce different colors, as can be seen from Table 2 the relationship between the amount of ferrous ammonium sulfate and the color parameter index of the green cotton fiber after treatment. The color parameter indexes are K / S, L, a, b and ΔE. K / S value indicates the color depth; L indicates the brightness of the sample color, the larger the L value, the lighter the sample color, and the smaller the sample color is thicker; the larger the positive value of a, the redder the shade, and the negati...

Abstract

The invention relates to the technical field of textile and in particular relates to a treatment method for a green cotton fiber. The treatment method for the green cotton fiber comprises the following steps: mixing ammonium ferrous sulfate with an emulsification extraction solution which comprises a refining agent and an extracting agent to prepare a treatment solution capable of showing capillary effect and toning color light; putting the green cotton fiber into the treatment solution for treating; and washing and drying the green cotton fiber which is treated by the treatment solution. According to the treatment method for the green cotton fiber, a one-bath method is adopted, so that the green cotton fiber is treated by the emulsification extraction solution and ammonium ferrous sulfate; color fixation treatment of the green cotton fiber is carried out by using ammonium ferrous sulfate after a good hydrophilic base is obtained; the light fastness is improved; and the color fastness to soaping and the perspiration resistance color fastness are simultaneously improved.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a method for processing green 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 "the darling of the 21st century" and...
