Problems solved by technology

[0006] In the Chinese patent application 201110279490.X, a method for preparing cotton-like fabrics by the alkali reduction method is disclosed. The prepared products feel fluffy, soft in luster, and have good air permeability. However, the project processing process is complicated, and the implementation time is too long. The temperature is too high, and the efficiency is low, and the utilization of lye is small

Embodiment １

[0023] Example 1. Liquid alkali treated polyester fiber cloth

[0024] 45 kilograms of 40% liquid caustic soda, wherein sodium hydroxide content is 18 kilograms, water 27 kilograms, add water 48 kilograms again, 5 kilograms of hydrolysis accelerator cetyl dimethyl benzyl ammonium chloride, 2 kilograms of ethanol, stir Prepare an alkaline solution, stir and heat to 60°C, immerse 50 kg of polyester fiber cloth in the above hot alkaline solution, the bath ratio is 1:2, soak for 5 minutes, take it out, rinse it with industrial water steam, and use Ph value test paper Monitor the Ph value of the dripping water. After 10 minutes, the Ph value of the dripping water is about 7. Continue to rinse with water steam for 5 minutes to ensure that it is cleaned, and then dry it. Randomly select the water that has undergone alkali reduction treatment and has not undergone alkali reduction treatment. Each of the 3 small pieces processed by the amount is about 1mm 2 The sample cloth was obse...

Embodiment 2

[0025] Example 2. Sodium hydroxide solution treated glass fiber cloth

[0026] Put 80 kg of water into 10 kg of sodium hydroxide, add 0.1 kg of triethylamine and 10 kg of ethanol, stir and heat to 100°C, and roll a glass fiber with a width of 1.5 meters, a length of 10 meters and a mass of about 10 kg. Put the cloth into the above-mentioned hot lye with a bath ratio of 1:10. After soaking for 60 minutes, take out the glass fiber cloth, put it on the above-mentioned lye, fumigate and wash it about 10cm away from the liquid surface. Use Ph value test paper to monitor the Ph value of the dripping water. After 30 minutes, the Ph value of the dripping water is about 8. Continue to wash with this water vapor for about 10 minutes to ensure that the sodium hydroxide absorbed by the glass fiber is cleaned, and then dry Dry, randomly take 3 small pieces of about 1mm each that have been treated by this method and those that have not been treated with alkali solution 2 Glass fiber clot...

Embodiment 3

[0027] Example 3. Potassium hydroxide solution treated nylon cloth

[0028] Put 500 grams of potassium hydroxide into 20 kilograms of ethanol, add 75 kilograms of water, then add 3 kilograms of ammonium sulfate and 2 kilograms of dihexadecyldimethylammonium bromide, stir and heat to 80 ° C, and put 1 kilogram of nylon cloth Put it into the above-mentioned hot lye, the bath ratio is 1:100, after soaking for 30 minutes, take out the nylon cloth, rinse it with industrial water steam after taking it out, use the Ph value test paper to monitor the Ph value of the dripping water, after 5 minutes, the dripping The pH value of the water is about 7, continue to rinse with water steam for 5 minutes to ensure washing, and then dry. Compared with the untreated nylon cloth, the above-mentioned treated nylon cloth has a more fluffy and comfortable hand feeling, and has better dyeability with water-based dyes. The above-mentioned treated nylon cloth and the steel plate are bonded with epo...

Abstract

The invention relates to an alkali de-weighting treatment method of fiber or fabric, and the method is characterized by comprising the following steps of preparing alkali solution, wherein the alkali solution contains the following components in parts by weight: 0.5 to 18 parts of alkali (preferably 5 to 10 parts of alkali), 75 to 98 parts of water (preferably 85 to 95 parts of water), 0.1 to 5 parts of hydrolysis promoter (preferably 1 to 3 parts of hydrolysis promote), and 1 to 20 parts of alcohol (preferably 5 to 15 parts of alcohol; placing the fibers or fabric into the well-prepared alkali solution, wherein the bath ratio is 1:2 to 1:100 (preferably 1: 5 to 1:30), treating the fibers or fabric for 5 to 60 minutes under the temperature condition of 60 to 100 DEG C, washing samples after the treatment, detecting a pH value of the water after the final washing of the samples, ending the washing when the pH value is alkalescent or neutral, and drying the fibers or the fabric in the air or in an oven. The fibers or the fabric after being treated is looser to touch and better in dyeing property for a hydrophobic dye. The surface of the fibers and the fabric after being treated has multiple micropores or defects through the observation of an electric mirror, so that the fibers or the fabric can form an embedding structure with bond, and better bonding property can be achieved.

Description

technical field [0001] The invention relates to a method for surface treatment of fibers or fabrics, in particular to a method for surface treatment of fibers or fabrics by using alkali weight reduction. Background technique [0002] People have always been interested in the surface properties of fabrics. The main methods used in the study of surface modification of fabric fibers at home and abroad include surface grafting, irradiation, surface treatment with coupling agents, plasma and other surface modification methods. Surface modification can give new properties to the surface without changing the properties of the material and its products, such as hydrophilic (repellent) or hydrophilic (repellent) oil, adhesion, antistatic, dyeability, aging resistance properties, biocompatibility, etc. [0003] In the industry, glass fiber has been widely used as a reinforcing material, but its surface has poor bonding performance with organic or polymer materials, and it is easy to ...
