A kind of manufacturing method of four-layer composite spunlaced nonwoven fabric

Abstract

The invention discloses a four-layer composite spunlace non-woven fabric and a method for manufacturing the same. The four-layer composite spunlace non-woven fabric comprises a staple fiber layer (1) and a carded fiber layer (2). A filament fiber layer (3) or a hot-rolling cloth layer (5), a water absorption fiber web layer (4) and the carded fiber layer (2) are sequentially laid on the staple fiber layer (1), and the staple fiber layer (1), the filament fiber layer (3) or the hot-rolling cloth layer (5), the water absorption fiber web layer (4) and the carded fiber layer (2) are integrally compounded with one another by means of spunlace. The four-layer composite spunlace non-woven fabric and the method have the advantages that the four-layer composite spunlace non-woven fabric is simple in structure and comprises the staple fiber layer, the filament fiber layer or the hot-rolling cloth layer, the water absorption fiber web layer and the carded fiber layer, and the four layers are integrally compounded with one another by the aid of spunlace processes; the four-layer composite spunlace non-woven fabric has a characteristic of high strength of spun-bonded products and the high water absorption of the water absorption fiber web layer and pulp fibers, and feels soft, thick and solid owing to four-layer structures; the longitudinal and transverse strength of the four-layer composite spunlace non-woven fabric can be enhanced by the filament fiber layer, the four-layer composite spunlace non-woven fabric can be guaranteed against deforming, and accordingly the shortcoming that common spunlace products are vulnerable to deformation due to excessively low strength can be overcome; the four-layer composite spunlace non-woven fabric comprises fluff pulp and the pulp fibers, and accordingly the production cost of the four-layer composite spunlace non-woven fabric can be reduced.

Description

technical field [0001] The invention relates to a composite nonwoven fabric and a manufacturing method thereof, in particular to a manufacturing method of a four-layer composite spunlace nonwoven fabric. Background technique [0002] With the continuous improvement of people's living standards, various spunlace nonwoven products are gradually penetrating into various aspects of life, medical treatment and industry. These application fields require the product to have a certain strength and water absorption performance. Although ordinary spunlace products can basically meet the above requirements, they are prone to deformation due to low strength, and the use effect and hand feel will be affected accordingly. Especially as sanitary products such as diapers and wet wipes, adult incontinence products and their wipes, baby care wipes, etc. that are used daily by women and babies, they are required to have high strength, no deformation, no lint, good moisture absorption and water...

Problems solved by technology

These application fields require the product to have a certain use strength and water absorption performance. Although ordinary spunlace products can basically meet the above requirements, they are prone to deformation due to low use strength, and the use effect and feel are affected accordingly.

Especially as sanitary products such as diapers and wet wipes, adult incontinence products and their wipes, baby care wipes, etc. that are used daily by women and babies, they are required to have high strength, no deformation, no lint, good moisture absorption and water retention, and at the same time feel Thick and clear lines, while the existing spunlace nonwoven products are two-layer wood pulp spunlace composite products. Because they are made of short fibers, they are easy to deform during the wiping process, and the wood pulp will adhere to the surface after wiping. The surface layer of the object to be wiped is prone to crumbs and lint during the wiping process
