Problems solved by technology

However, for the processing of fabrics woven with pure cotton moisture-absorbing and heating yarns, the disadvantage of the prior art is that the heating temperature is low. Existing fabrics woven with pure cotton moisture-absorbing and heating yarns are tested, and the heating effect often does not reach the standard. little improvement

Embodiment 1

[0019] When processing the pure cotton moisture-absorbing and heat-generating knitted fabric in this embodiment, the method steps include refining, bleaching, and dyeing processes in sequence; several processes before dyeing are the same as the dyeing and finishing processes in the prior art, and will not be repeated here; After the dyed pure cotton fabric is subjected to normal soaping treatment, it is washed, and then heat treatment process is added.

[0020] The added exothermic processing procedure includes the following steps:

[0021] (1) Acid treatment: add 6g / L citric acid, treat at 40°C for 20 minutes; then wash with water at 30°C for 10 minutes;

[0022] (2) Alkali treatment: add 9g / L baking soda, treat at 40°C for 20min; then add 0.3g / L metal ion chelating dispersant SS-202 to it; finally wash with water at 30°C for 5min, wash with water The process is repeated twice.

Embodiment 2

[0024] The pure cotton fabric processing steps before the heating processing procedure are the same as in Example 1;

[0025] The heat treatment process includes the following steps:

[0026] (1) Acid treatment: add 3g / L citric acid, treat at 35°C for 15 minutes; then wash with water at 30°C for 8 minutes;

[0027] (2) Alkali treatment: add 6g / L baking soda, treat at 35°C for 15min; then add 0.1g / L metal ion chelating dispersant SS-202 to it; finally wash with water at 30°C for 3min, wash with water The process is repeated twice.

Embodiment 3

[0029] The pure cotton fabric processing steps before the heating processing procedure are the same as in Example 1;

[0030] The heat treatment process includes the following steps:

[0031] (1) Acid treatment: add 9g / L citric acid, treat at 45°C for 30min; then wash with water at 35°C for 15min;

[0032] (2) Alkali treatment: add 12g / L baking soda, treat at 45°C for 25min; then add 0.5g / L metal ion chelating dispersant SS-202 to it; finally wash with water at 35°C for 8min, wash with water The process was repeated four times.

Abstract

The invention belongs to the technical field of cloth dyeing and finishing processing, and particularly relates to a method for improving moisture absorption and heating effects of pure cotton fabric. The method comprises the following steps of refining, bleaching, dyeing, soaping the dyed pure cotton fabric, washing, and heating, wherein the heating processing comprises the following steps that citric acid is added for acid treatment; sodium bicarbonate is added for alkali treatment; and meanwhile, a certain amount of metal ion chelating dispersing agent is added for treating the pure cotton fabric, and finally the needed product is obtained after repeated washing. According to the method provided by the invention, through dyeing and finishing processing, especially the added heating processing treatment procedure, the moisture absorption and heating performance of the pure cotton fabric is further improved, the heating effect of the fabric is enhanced, the heating effect of the processed pure cotton fabric can be increased by more than 3 degrees, and the moisture absorption and heating effect is relatively good.

Description

technical field [0001] The invention belongs to the technical field of cloth dyeing and finishing, and in particular relates to a method for improving the moisture absorption and heating effect of pure cotton fabrics. Background technique [0002] Traditional heat preservation is mainly to prevent the heat emitted by the body from escaping. With the further development of science and technology, the textile industry has developed a self-heating fiber. The function of the so-called self-heating fiber in terms of heat is limited, because the Starting from the law of conservation, the heat energy that emerges can only be obtained from the skin respiration of the human body. In the prior art, by adding heat-sensitive phase-change materials to acrylic fibers, heat can be absorbed, stored and released in the form of latent heat, which can be converted into solid and liquid states during temperature changes, thereby achieving the effects of heat absorption and heat generation.
