Technical Field

The invention belongs to the technical field of dyeing and finishing of cloth, and particularly relates to a method for improving the moisture absorption and heating effects of a pure cotton fabric.

Background

The traditional heat preservation is mainly used for preventing heat emitted by the body from escaping, and with the further development of science and technology, the textile industry develops a self-heating fiber, the function of the self-heating fiber in the aspect of heating is limited, because the heat energy generated from the conservation law of materials can only be obtained from the skin respiration of the human body. In the prior art, the thermosensitive phase change material is added into the acrylic fiber, so that heat can be absorbed, stored and released in a latent heat mode, and the thermosensitive phase change material can be converted into a solid state and a liquid state in temperature change, so that the effects of heat absorption and heat generation are achieved.

At present, a moisture-absorbing and heating fabric is also developed in the textile industry, is woven by pure cotton moisture-absorbing and heating yarns, and accords with the natural and environment-friendly concept of the public. However, for the processing of the fabric knitted by the pure cotton moisture absorption heating yarns, the defects of the prior art are that the heating temperature is low, the fabric knitted by the existing pure cotton moisture absorption heating yarns is detected, the heating effect often cannot reach the standard, and the temperature is not greatly increased.

Disclosure of Invention

The invention aims to solve the problems in the prior art and provides a method for improving the moisture absorption and heating effects of a pure cotton fabric, the method further improves the moisture absorption and heating properties of the pure cotton fabric through dyeing and finishing, the heating effect of the fabric is enhanced, the heating temperature effect of the processed pure cotton fabric can be increased by more than 3 ℃, and the moisture absorption and heating effects are good.

The technical scheme of the invention is as follows:

a method for improving the moisture absorption and heating effects of pure cotton fabric comprises the working procedures of refining, bleaching and dyeing, wherein the dyed pure cotton fabric is washed after soaping treatment and then subjected to a heating processing working procedure, and the processing working procedure comprises the following steps:

(1) acid treatment: adding 3-9 g/L citric acid, and treating for 15-30 min at 35-45 ℃; then washing with water at the temperature of 30-35 ℃ for 5-15 min;

(2) alkali treatment: adding 6-12 g/L baking soda, and treating for 15-25 min at 35-45 ℃; then adding 0.1-0.5 g/L of metal ion chelating dispersant into the solution; and finally, washing for 3-8 min at the temperature of 30-35 ℃, and repeating the washing for 2-4 times.

Furthermore, the pure cotton fabric is woven by moisture absorption heating yarns. The moisture absorption heating yarn is a special fiber material and actively generates heat by absorbing moisture emitted by a human body; the pure cotton fabric made of raw materials including the moisture-absorbing heating yarns can be actively heated by 2-4 ℃.

Further, 6g/L of citric acid is added in the step (1), and the mixture is treated for 20min at the temperature of 40 ℃; then washed with water at 30 ℃ for 10 min.

Further, 9g/L of baking soda is added in the step (2), and the mixture is treated for 20min at the temperature of 40 ℃; then 0.3g/L of metal ion chelating dispersant SS-202 is added into the solution; finally washing with water at 30 deg.C for 5min, and repeating washing with water for 2 times.
