Abstract

The invention discloses a CSC three-layer composite spunlaced nonwoven, and is characterized in that the nonwoven has a three-layer structure, the upper layer and the lower layer are 100% terylene layers which have been carded into nets, and the intermediate layer is PP spoubond nonwoven. A method for producing the spunlaced nonwoven comprises steps of opening and cleaning polyester fiber, carding into nets, compositely forming the upper layer, the intermediate layer and the lower layer with spunlace, and drying. The invention provides the three-layer sereoscopic composite spunlaced nonwoven with characteristics of high strength, soft touch, good dust-absorbing effect, no crumbs and low cost, and the method for producing the nonwoven.

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. Nonwovens have the advantages of excellent performance, high use value and low cost. With the continuous improvement of people's living standards, various nonwoven products are entering thousands of households, involving all aspects of people's life and work, and wipes are one of them. Wipes include dry wipes and wet wipes. Dry wipes are generally made of polyester, and are widely used in industrial wipes, ...
