Embodiment

[0018] The 75% green cotton grey cloth and the pre-treatment auxiliary agent are treated at a mass ratio of 1:20 and a temperature of 60-130 DEG C for 15-75 minutes to make the grey cloth wool effect reach 10-12cm / 30min.

[0019] That is, 12 kinds of pre-treatment auxiliaries were used to treat 75% green cotton grey cloth under the conditions of 90°C and 30 minutes, and the wool effect value and light fastness of the treated fabrics were analyzed and compared, as shown in Table 1.

[0020] Table 1 Comparison of effects of different pretreatment additives

[0021]

[0022]

[0023] It can be seen from Table 1 that the treated green cotton fabrics have very good wool effects, and they are not much different from each other; the light fastness is only improved by 1-1.5 grades than the grey fabric, which has not yet reached the daily requirements of conventional textiles. The light fastness is level 4 standard. Among them, the determination of wool effect (determination is in accordance...

Abstract

The invention provides a method for improving the light fastness of natural green colored cotton. The method comprises the steps as follows: green colored cotton grey cloth is pre-processed through preprocessing addition agents; metal complexation and softening treatment are carried out after the capillary effect of the grey cloth reaches 10 to 12 cm/30min; and then the light fastness of the grey cloth is enabled to reach 4 level, so that green colored cotton with beautiful color and stable performance is obtained. The sample production can be carried out by adopting the prescription and the technology of the processing method, so that the technology achieves good reproducibility, the light fastness of natural green colored cotton reaches 4 level, and good capillary effect and hand feeling can be achieved. Fabrics that are obtained by processing 75 percent of green colored cotton by adopting the method achieve beautiful colors and stable performances, and all the indexes of the fabrics can meet the requirements (National Standard 18401).

Description

Technical field [0001] The invention relates to the technical field of processing green colored cotton, in particular to a method for improving the light fastness of natural green colored cotton. Background technique [0002] Colored cotton is a new type of textile material whose fibers have color when the cotton is spit. No pesticides, fertilizers, herbicides and other chemicals are applied during the planting process; during the processing, no bleaching, printing and dyeing processes are carried out, which not only greatly reduces the grey fabric It is an environmentally friendly and green product because it can reduce the chemical residues, reduce energy consumption, save a lot of dyeing water, and reduce the pressure of sewage treatment and environmental pollution. At the same time, it has the characteristics of comfort, no skin irritation, antistatic, good moisture permeability, etc., which is widely favored by consumers and has a broad market prospect. [0003] However, the ...
