Abstract

The invention discloses a water-repellent polyolefin polyester fabric. The fabric comprises a polyolefin polyester fabric substrate and an organosilicon water-repellent finishing agent latex film arranged on the surface of the substrate; by mass, 10 parts of a water-repellent finishing agent, 4 parts of a thickener and 86 parts of water are mixed and fully stirred to form a coating agent, the viscosity reaches 35,000-40,000 CPS, the coating agent coats the polyolefin polyester fabric substrate with the application amount of 70-90 parts / m<2>, drying is conducted at 70 DEG C for 5 min, baking isconducted at 160 DEG C for 2 min, and the water-repellent polyolefin polyester fabric is prepared; the organosilicon water-repellent finishing agent is formed by blending an organosilicon modified acrylate emulsion and an organosilicon modified polyurethane emulsion according to the mass ratio of 1:1.2-1:2. Through the modification of organosilicon, the polyolefin polyester fabric has good waterproof performance and breathability.

Description

technical field [0001] The invention relates to a functional fabric, in particular to a water-repellent polyolefin elastic fabric, which belongs to the field of functional textile fabrics. Background technique [0002] In recent years, with the rapid development of social life, people's living standards have also improved, and the requirements for clothing, food, housing, and transportation have become higher and higher. Clothes are required to be comfortable, moisture-permeable, sweat-wicking, Anti-wrinkle, waterproof and oil-proof, easy to decontaminate, anti-ultraviolet, anti-static and other functions. Different industries have different requirements for the clothing of employees. For example, outdoor sports personnel require the outer fabric of clothing to be waterproof and easy to decontaminate. [0003] Elastic fabrics are fabrics made by weaving yarns containing elastic fibers with shuttle looms. Only the fabric with elastic fibers in the warp is called warp elasti...
