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...

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.

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 industry standard SN/T 1689.1-2005 of the People's Republic of China, Determination of the Dynamic Transport Performance of Porous Materials for Liquid Water Part 1: Textiles. Measurement results such as image 3 shown. The inner surface in the figure represents the side of the fabric close to the skin, indicating the change process of the water content of the surface during the measurement process, and the outer surface represents the side of the fabric away from the skin. image 3 The two curves show that when a certain amount of simulated sweat (0.15 grams) reaches the inner surface of the fabric during the measurement, the sweat can be quickly transferred to the outer surface of the fabric, so that the moisture content of the outer surface also rises almost simultaneously. At the same time, the measurement result (MAX.wetted Radii, the maximum wetted radius) of 30mm indicates that the sweat spreads on both sides of the fabric within the measurement time (120 seconds) and its expansion radius reaches 30MM, which shows that sweat can spread rapidly on the fabric. These indicators all indicate that the treated fabric has good hydrophilic properties.
[0047] Table 1 is the measurement result data of the liquid water transfer characteristics of the wool fabric treated in Example 1.
[0048] Table 1
[0049]
[0050] from image 3 It can be obtained from Table 1 that liquid water can quickly penetrate to the lower surface when it reaches the surface of the fabric, and has a fast moisture absorption speed. The wetting time of the upper and lower surfaces is about 3 seconds respectively, and it can quickly spread on the upper and lower surfaces of the fabric, and its expansion radius reaches 30mm, which means that the treated fabric has good hydrophilic properties.

Example Embodiment

[0051] Example 2
[0052] SiO with a particle size of 100 nm 2 5 parts by weight are mixed with 100ml of deionized water, stirred uniformly to form a solution, the pH of the solution is adjusted to 6 with acetic acid, 5 parts by weight of silver-based antibacterial agent with the function of releasing negative ions is added, mixed evenly, and nano finishing liquid is made. Wool fabric to be treated is soaked in the aqueous ethanol solution of 20: 80 (volume ratio) for 60 minutes, then soaked in the above-mentioned nano finishing liquid, the bath ratio of fabric quality and nano finishing liquid is 1: 80, and constant temperature water bath is 100 ℃, Constant temperature treatment for 0.5 hours. Rinse the fabric treated with the above-mentioned nano-finishing solution, dry it by rolling, and then put it into an oven at 100° C. for drying.
[0053] With the measurement method described in Example 1, the dynamic change process of the water content on both surfaces of the wool fabric treated in Example 2 is measured by using a fabric liquid water dynamic transfer characteristic measuring instrument.
[0054] Figure 5 Table 2 and Table 2 are the measurement results of the liquid water transfer characteristics of wool fabrics treated in this embodiment.
[0055] Table 2
[0056]
[0057] From the measurement results, it can be concluded that liquid water can quickly penetrate to the lower surface when it reaches the surface of the fabric, and has a fast moisture absorption speed. The wetting time of the upper and lower surfaces is about 4 seconds respectively, and it can quickly expand on the upper and lower surfaces of the fabric, and its expansion radius also reaches 30mm.

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.
