Problems solved by technology

[0003] 1. The cost of viscose fiber is rising year by year and the global supply is tight, resulting in a relatively high cost of products;
[0004] 2. Polyester fiber is a petroleum product and cannot be degraded in the natural environment, resulting in waste products that cause waste pollution to the environment

Abstract

The invention discloses a CPC three-layer composite spunlaced nonwoven fabric which is of a three-layer structure, wherein the upper and lower layers are 100% degradable viscose fiber layers combed into nets, and the middle layer is a pulp fiber paper layer. The invention also discloses a production method of the nonwoven fabric, comprising the steps of: viscose fiber opening and picking, combing into nets, paper conveying, spunlaced composite shaping of the upper layer, middle layer and lower layer, drying and the like. The nonwoven fabric adopts wood pulp fiber paper to replace partial viscose fiber with higher price, so that the production cost is effectively lowered; and the finished product has the advantages of puffy and full hand feeling, good hydroscopicity, good dedusting effect, no leavings falling and 100% degradability.

Description

technical field [0001] The invention relates to a composite spunlace nonwoven fabric with a three-layer structure and a production method of the nonwoven fabric. Background technique [0002] Spunlaced nonwovens have a wide range of applications and can be used in many fields such as life, medical treatment, and industry. For example, daily necessities can be used for wipes, wet face towels, compressed towels, etc.; medical and health can be used for medical sheets, pillowcases, tablecloths, etc.; industrial supplies can be used for wipes, laboratory work clothes, etc. With the widening of the application field of nonwovens, some places have higher and higher requirements on the quality, applicability and function of the product. The product must not only have a certain function, but also have multiple functions or higher performance. , to meet high-tech conditions or use in special circumstances. The existing spunlace nonwovens basically use viscose and polyester as raw m...
