Problems solved by technology

These water repellents have common weaknesses: no oil repellency, no anti-fouling, poor washability
[0003] At present, fluorocarbons are widely used in water and oil repellent functional finishing. Because of their excellent water repellency, oil repellency, stain resistance and air permeability, they are favored by the market and widely used in high-grade textiles, leather and other industries. Similar finishing agents are expensive, non-degradable and have certain biological toxicity

Embodiment 1

[0019] Example 1: A fabric water-repellent and oil-repellent nano-finishing agent, main components: 10 g of nano-zinc oxide with a particle size of 100 nm, 2 g of ethylsilane with a molar concentration of 0.2 mol / L, and a fatty acyl amino acid with a molar concentration of 0.4 mol / L Type surfactant 5g, absolute ethanol 2g, acetic acid 1g, deionized water 80g. The preparation process is as follows:

[0020] (1) Add nano-zinc oxide into ethylsilane and start stirring (200r / min, 60min);

[0021] (2) Add deionized water, acetic acid and ethanol in sequence and stir rapidly (800r / min, 30min);

[0022] (3) Add the fatty acyl amino acid surfactant and continue stirring until fully mixed.

[0023] The present invention uses charge transfer complexes, that is, silane coupling agents, to chemically adsorb the surface of nano-zinc oxide, thereby increasing the compatibility of nanoparticles to the matrix, improving a series of surface properties such as its wetting and dispersion, and ...

Abstract

The invention discloses a water and oil repellent nanometer finishing agent for fabric. The water and oil repellent nanometer finishing agent comprises nanometer zinc oxide, a silane coupling agent, a surfactant, ethanol, acetic acid and deionized water. The water and oil repellent nanometer finishing agent is applicable to fabric for woven clothing and home textile fabric; the water and oil repellent effects and the stability of the fabric can be obviously improved; the preparation technology is simple and convenient; and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of fabric treatment, and in particular relates to a fabric water-repellent and oil-repellent nano-finishing agent. Background technique [0002] The water repellency of the fabric refers to the performance of the fabric to drop water droplets from its surface. The purpose of water repellent finishing is to prevent the wetting of the fabric by water, and use the additional pressure of the fabric capillary to prevent the penetration of liquid water, but still maintain the fabric. Excellent breathability and moisture permeability. Clothing made of this kind of fabric not only has good waterproof performance, but also can quickly discharge sweat vapor from the body surface, keeping the clothing dry and warm, thus greatly improving the comfort of the clothing. , Expanding the scope of application of fabrics, water-repellent finishing fabrics were first used to produce military uniforms and protective clothing, an...
