Problems solved by technology

[0003] Non-woven fabrics are widely used in industrial and medical fields. The existing non-woven fabrics have poor waterproof and breathable effects, and the flame retardancy of non-woven fabrics is also relatively poor. The non-woven fabrics produced are relatively hard, soft and light-resistant. poor

Abstract

The invention discloses a waterproof and breathable non-woven fabric and a production process thereof. The waterproof and breathable non-woven fabric comprises the following raw materials in parts byweight: 50-70 parts of polypropylene, 5-10 parts of polyester resin, 3-5 parts of an additive, 5-10 parts of a flame retardant, and 3-5 parts of a dyeing agent. In the invention, the production process of the waterproof and breathable non-woven fabric is strictly controlled, by strictly controlling the proportion of all components of the waterproof and breathable non-woven fabric and production process parameters, and by adding the flame retardant to the raw material additive, the flame retardant performance of the produced non-woven fabric is improved, the additional sodium thiosulfate can improve the light resistance of the fabric, meanwhile heat degradation masterbatch and a softener can effectively improve the softness of the fabric and enhance the comfortableness. Meanwhile, under thecontinuous conveying of a web forming conveyor belt, a PE polymer gas-permeable membrane is added to improve the waterproof and breathable performance of the non-woven fabric, so that the non-woven fabric is suitable for extensive promotion.

Description

technical field [0001] The invention relates to the technical field of textile production, in particular to a waterproof and breathable non-woven fabric and a production process thereof. Background technique [0002] Non-woven fabric (English name: Non Woven Fabric or Nonwoven cloth), also known as non-woven fabric, is composed of oriented or random fibers. It is called cloth because of its appearance and certain properties. Non-woven fabrics have the characteristics of moisture-proof, breathable, flexible, light weight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color, low in price, and recyclable. For example, polypropylene (pp material) pellets are mostly used as raw materials, which are produced by continuous one-step process of high-temperature melting, spinning, laying, and hot-pressing coiling. [0003] Non-woven fabrics are widely used in industrial and medical fields. The existing non-woven fabrics have poor waterproof and breathable...
