Abstract

The invention discloses a preparation method of a hydrophobic and oleophobic agent for fabric. The hydrophobic and oleophobic agent for the fabric is prepared from the following raw materials in partsby weight: 15-25 parts of resin, 2-4 parts of a silane coupling agent, 4-10 parts of silica sol, 10-20 parts of amino-silicone oil, 0.5-1 part of octadecyltrichlorosilane, 10-20 parts of lotus leaf juice, 0.5-1.5 parts of perfluorinated acrylic emulsion and 50-100 parts of ethanol. After the hydrophobic and oleophilic agent for the fabric is applied to the fabric, the hydrophobic and oleophilic contact angle of the fabric reaches 130 degrees or larger. According to the hydrophobic and oleophobic agent for the fabric, the preparation process is simple and easy to operate, the raw materials arecheap and easily available, and the hydrophobic and oleophobic agent is non-toxic, harmless, non-irritant to human bodies and low in volatility; toughness, strength and hand feeling of the finished fabric are basically not affected.

Description

technical field [0001] The invention belongs to the technical field of textile auxiliaries, and more specifically relates to a fabric hydrophobic and oleophobic agent. Background technique [0002] At present, most fabrics have a series of problems such as being easily wetted by water, stained with oil, and difficult to wash after being stained. This leads to a series of problems such as time-consuming and labor-intensive fabric care, large washing water consumption, and environmental pollution caused by detergents. With the improvement of human living standards, consumers have put forward unprecedented high requirements for waterproof, oil-proof and easy-to-decontamination fabrics of textile fabrics. [0003] The hydrophobicity and oleophobicity of fabrics refer to the resistance properties of fabrics to water and low surface tension oils. The purpose of hydrophobic and oleophobic finishing is to prevent water and oil from wetting the fabric, and the fabric still maintain...
