Problems solved by technology

[0003] The hydrophobic finishing of textiles, especially the finishing of synthetic fibers, generally adopts coating finishing, but the durability of coating finishing is poor.
With the development of new technologies, technologies such as plasma and electron radiation have been applied, but these new technologies have limited their industrial application due to the inhomogeneity and repeatability of finishing products and the cost of equipment.

Abstract

The invention discloses a finishing method of hydrophobic and oleophobic fabric based on dacron or polyester cotton, and belongs to the technical field of functional textiles. In the method disclosed by the invention, the dacron or polyester cotton fabric is processed by using a silica sol and organic fluorine compound water repellent, and the textile fabric is processed in combination with surface roughness finishing or low surface energy finishing, so that the hydrophobic and oleophobic fabric is obtained. The finishing method uses a traditional rolling baking technology, is low in equipment requirement, belongs to a continuous production technology, and is good in product uniformity and repeatability, time-saving and high-efficiency. Due to the fact that the whole finishing process is carried out in a slightly neutral condition, the baking time is short, and the damage on the fabric is little. The method can be used for finishing the hydrophobic and oleophobic functions of the dacron and polyester cotton blended fabric.

Description

technical field [0001] The invention relates to a method for finishing polyester or polyester-cotton hydrophobic and oleophobic fabrics, which is suitable for post-finishing polyester and polyester-cotton fabrics and belongs to the technical field of functional textiles. 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. 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 oleophob...
