A kind of waterproof and oil-proof non-woven fabric and its manufacturing process

Abstract

The invention discloses a waterproof and oil-proof non-woven fabric and a manufacturing process thereof. The waterproof and oil-proof non-woven fabric is made of the following raw materials in parts by weight: 65-75 parts of polypropylene, maleic anhydride grafted ethylene-octyl 16-22 parts of vinylene copolymer, 8-13 parts of PP-g-AA graft copolymer, 2-4 parts of amino-modified polysiloxane emulsion, 5-8 parts of polyvinylidene fluoride-hexafluoropropylene copolymer, 4-7 parts of fluorine-containing polyacrylic acid ester, 9-15 parts of filler. The waterproof and oil-proof non-woven fabric of the present invention has a good waterproof and oil-proof effect, and the waterproof and oil-proof effect is long-lasting, and it is not easy to lose the waterproof and oil-proof performance when it is contacted with a solvent or washed or rubbed with other objects afterwards. In addition, it also has good elasticity And softness, non-irritating to the skin, high wearing comfort.

Description

technical field [0001] The invention relates to the technical field of non-woven fabrics, in particular to a waterproof and oil-proof non-woven fabric and a manufacturing process thereof. Background technique [0002] The fibers used in the production of non-woven fabrics are mainly polypropylene (PP) and polyester (PET). In addition, there are nylon (PA), viscose fiber, acrylic fiber, polyethylene fiber (HDPE), and chlorine fiber (PVC). According to application requirements, non-woven fabrics are divided into two categories: disposable application type and durable type. [0003] According to the production process, it is divided into: [0004] 1. Spunlace non-woven fabric: The spunlace process is to spray high-pressure fine water flow onto one or more layers of fiber nets, so that the fibers are entangled with each other, so that the fiber nets can be reinforced and have a certain strength. [0005] 2. Heat-bonded non-woven fabric: heat-bonded non-woven fabric refers to ...

AI Technical Summary

Problems solved by technology

[0015] 1. The existing method of preparing waterproof and oil-proof non-woven fabrics is generally to manufacture non-functional non-woven fabrics first, and then immerse the non-woven fabrics in the three-proof finishing agent for impregnation, so as to obtain waterproof and oil-proof non-woven fabrics. High-performance non-woven fabrics, but although there are many kinds of polymers in the method, the waterproof and oil-proof non-woven fabrics obtained have poor waterproof and oil-proof performance, and the waterproof and oil-proof performance (function) is temporary. It is easy to lose the waterproof and oil-proof performance when rubbing against other objects;

[0016] 2. Waterproof and oil-proof non-woven fabrics have poor elasticity, low softness, slightly irritating to the skin, and poor comfort
