Problems solved by technology

However, in the current non-woven fabric market, there are still few types of non-woven fabrics with high elasticity. One of the important reasons is that it is difficult to match the product formula of elastic non-woven fabrics, and the spinning process is not easy to adjust and master, resulting in elasticity. It is difficult to spin the product, and there will be problems such as dripping and broken wires during the spinning process
Because the process is not adjusted in place, the product has more parallel wires, rough hand feeling and poor resilience. Such products basically have no application value.

Abstract

The invention discloses a high elasticity nonwoven fabric and a production process thereof, wherein the high elasticity nonwoven fabric is a compound of three layers of spunbond nonwoven fabrics, each layer of the spunbond nonwoven fabrics is prepared from, by weight, 74%-96% of ethylene propylene hypocrystalline copolymer, 1.5%-24% of polypropylene, 0.029%-0.096% of polyethylene, 0.27%-1.08% of saturated erucyl amide, 0.04%-0.156% of phenols antioxidant and 0.04%-0.22% of phosphite ester antioxidant, and 0.38%-1.59% of titanium dioxide.

Description

technical field [0001] The invention relates to the technical field of non-woven fabric materials, in particular to a high-elastic non-woven fabric and a production process thereof. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, have the advantages of short process flow, fast production speed, high output, low cost and wide application compared with traditional woven fabrics. With the continuous development of technology, the types and uses of nonwovens are becoming more and more diverse. However, in the current non-woven fabric market, there are still few types of non-woven fabrics with high elasticity. One of the important reasons is that it is difficult to match the product formula of elastic non-woven fabrics, and the spinning process is not easy to adjust and master, resulting in elasticity. It is difficult to spin the product, and there will be problems such as dripping and broken filaments during the spinning process. Because the p...
