Problems solved by technology

However, people have gradually discovered that clothing made of wool or even cashmere will feel very uncomfortable after sports and performances due to the poor moisture absorption and perspiration properties of wool.
This is because wool has a scale layer structure on the surface, and its fabric has a high porosity. After reaching a moisture absorption rate of 30%, sweat will be bound to the fiber without spreading, so its moisture absorption and moisture removal rate is low. The low rate of perspiration in the back causes discomfort to the human body
[0003] In order to improve the hydrophilicity of fabrics, a low-temperature plasma treatment technology has emerged in recent years, using plasma in a certain atmosphere to interact with the surface of fabrics, and introdu

Example Embodiment

[0044] Example 1

[0045] SiO with a particle size of 50 nm 2 Mix 1 part by weight of particles with 100 milliliters of deionized water, stir evenly to form a solution, adjust the pH of the obtained solution to 3 with HCl, and prepare a nano-finishing solution. Soak the wool cloth in 20:80 (volume ratio) ethanol aqueous solution for 60 minutes, take it out and soak it in the nano-finishing solution, the bath ratio is 1:80, the constant temperature water bath is 100°C, and the constant temperature treatment is 5 hours . Rinse the wool cloth treated with the above-mentioned nano-finishing solution, dry it by rolling, and then put it into an oven at 100° C. for drying.

[0046] The dynamic change process of the water content on both surfaces of the wool fabric treated in Example 1 was measured by using a fabric liquid water dynamic transfer characteristic measuring instrument. For the specific measurement method, please refer to the entry-exit inspection and quarantine industr...

[0058] Example 3

[0059] 15 parts by weight of sodium silicate, 8 parts by weight of ethylene-vinyl acetate and 100 ml of deionized water were evenly stirred to prepare a solution. Use HCl to adjust the pH of the solution to 5, add 5 parts by weight of a silver-based antibacterial agent, and mix evenly to prepare a nano-finishing solution. Soak woolen cloth in ethanol solution for 10 minutes, ethanol solution is 20% (volume ratio) aqueous solution, after taking it out, soak in the described nano finishing liquid, bath ratio is 1: 10, constant temperature water bath is 60 ℃, constant temperature Processed for 3 hours. Rinse the wool cloth treated with the above-mentioned nano-finishing liquid, dry it by rolling, and then put it into an oven at 120° C. for drying.

[0060] With the measurement method described in Example 1, the dynamic change process of the water content on both surfaces of the wool cloth treated in Example 3 was measured, and the results showed that the trea...

Abstract

The invention relates to a surface hydrophilic nanometer finishing method of a keratin porosint, which can fix nanometer materials on various fabrics through soaking-rolling-baking, increase the hydrophilicity and comfortableness of fabrics and wool fabrics in particular, and is in accordance with the new requirements of fabric properties from the people. The surface hydrophilic nanometer finishing method comprises the following steps: (1) prepare the nanometer finishing liquid according to steps; (2) soak the fabrics waiting for treatment in ethanol water, take the fabrics out, and soak the fabrics in the nanometer finishing liquid prepared in step (1) for constant temperature finishing; (3) rinse, roll and dry the fabrics treated in the nanometer finishing liquid.

Description

technical field [0001] The invention relates to a hydrophilized nano-finishing method for the surface of a keratin porous material fabric, in particular to a hydrophilized nano-treated method for the surface of a wool fabric. Background technique [0002] With the improvement of people's living standards, people have put forward diversified requirements for the grade and function of clothing. As the clothing fabric that is the most direct symbol of people's status, people are more pursuing high-end, and require fabrics to have functions such as comfort and health care, light weight, good moisture absorption and perspiration, and antibacterial and deodorizing properties. Therefore, functionalization such as light weight, comfort, health care, moisture absorption, perspiration, antibacterial, and deodorization has become a research hotspot in the textile industry. The comfort of the human body mainly depends on the heat generated by the human body itself, the loss of water an...
