Problems solved by technology

[0004] Finishing the fabric so that it can release negative ions is a newly developed technology, which is still in the stage of exploration, such as adding tourmaline fine particle textile fibers or spinning into porous fibers during the spinning process, or using tourmaline, carbon, etc. Powder and fine particles are dispersed in the coating agent for coating, etc., but there are still some problems to be solved, such as the combination of fine particles and textile fibers, the dispersibility of fine particles, and the bonding fastness of fine particles and textile fibers. and many more

Embodiment 1

[0036] (1) Preparation of finishing solution

[0037] 47.2g of γ-glycidyl ether propyl trimethoxysilane was added dropwise to 72g of an aqueous solution with a pH of 4 (adjusted with hydrochloric acid), and stirred at room temperature for 2 hours to obtain a transparent silicon-containing sol.

[0038] (2) Negative ion finishing

[0039] Put cotton poplin 4040×3372 in the above-mentioned sol finishing solution for two dipping and two rolling, pressure 3Kg / cm, dry in a blast oven at 105°C, wash with water or neutralize with alkali (remove excess acid on the fabric, avoid high temperature baking) Baking causes loss of fabric strength), followed by baking at 170° C. for 3 minutes.

[0040] (3) Negative ion test Gently rub at room temperature and test with IC-1000 tester, there are 4800 negative ions per cubic centimeter.

Embodiment 2

[0042] (1) Preparation of finishing solution

[0043] Add 47.2 g of γ-glycidyl ether propyl trimethoxysilane dropwise to 54 g of an aqueous solution with a pH of 4 (adjusted with hydrochloric acid), and stir at room temperature for 2 hours to obtain a transparent silicon-containing sol.

[0044] (2) Negative ion finishing

[0045] Put cotton poplin 4040×3372 in the above-mentioned sol finishing solution for two dipping and two rolling, pressure 3Kg / cm, dry in a blast oven at 105°C, wash with water or neutralize with alkali (remove excess acid on the fabric, avoid high temperature baking) Baking causes loss of fabric strength), followed by baking at 170° C. for 3 minutes.

[0046] (3) Negative ion test

[0047] After washing with water for 50 times, dry in the shade, rub gently at room temperature and test with IC-1000 tester, the number of negative ions per cubic centimeter is 5300.

Embodiment 3

[0049] (1) Preparation of sol finishing solution

[0050] Add 47.2 g of γ-glycidyl ether propyl trimethoxysilane dropwise to 54 g of an aqueous solution with a pH of 4 (adjusted with hydrochloric acid), and stir at room temperature for 2 hours to obtain a transparent silicon-containing sol.

[0051] (2) Negative ion finishing

[0052] Put cotton poplin 4040×3372 in the above-mentioned sol finishing solution for two dipping and two rolling, pressure 3Kg / cm, dry in a blast oven at 105°C, wash with water or neutralize with alkali (remove excess acid on the fabric, avoid high temperature baking) Baking causes loss of fabric strength), followed by baking at 170° C. for 3 minutes.

[0053] (3) Softener and adhesive post-treatment

[0054] In order to improve the hand feel of the fabric, its strength and the durability of nano-sol particle anion finishing, the fabric needs to be treated with softener and adhesive after anion finishing. details as follows:

[0055] The cellulose f...

Abstract

The present invention performs negative ion finishing of fabric by means of sol-gel technology, and in a rolling-stoving-roasting process with silicate ester as precursor for preparing stable transparent nanometer sol. During the negative ion finishing of cellulose, silk and other natural fiber and polyamide, polyester and other synthetic fiber, adhesive and softening agent are used to endow fabric with excellent and lasting negative ion performance and excellent hand feeling and comfort.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a sol-gel negative ion finishing method for fabrics including fibers such as cellulose, silk, polyamide and polyester. Background technique [0002] Sol-gel technology is mostly used in the preparation of nano-ceramic powders and membranes, and the research reports on textiles are rare. But according to the basic principles, it is feasible and meaningful to apply it to textiles to prepare functional fabrics. [0003] Using sol-gel technology, through padding or dipping treatment, transparent and highly adhesive metal or non-metal oxide films can be formed on various textiles. The type of precursor and the adsorption state of the film on the surface of the fabric can endow the fabric with different properties, such as anti-abrasion strength, antistatic property, tack / anti-adhesion, coloring, gloss, photochromism, UV stability, biocompatibility , biocatalysi...
