Abstract

The invention discloses a directly-lapped three-carding spunlace non-woven fabric. The fabric comprises a first fiber layer, a third fiber layer and a second fiber layer located between the first fiber layer and the third fiber layer, the second fiber layer comprises a plurality of mutually-spaced fiber areas, and the first fiber layer and the third fiber layer are hydrophilic fiber structure layers. The second fiber layer is a low-melting-point fiber structure layer, and the second fiber layer is subjected to hot melting at a plurality of fiber areas and is bonded with the first fiber layer and the third fiber layer. According to the non-woven fabric, the second fiber layer capable of being bonded through hot melting is arranged between the first hydrophilic fiber layer and the third hydrophilic fiber layer, and the fiber raw materials of the second fiber layer are lapped at intervals, so that the non-woven fabric can obtain a small longitudinal and transverse strength ratio without adopting a cross lapping process, the non-woven fabric can replace part of cross-lapped products, the application range and field of the directly-lapped non-woven fabric product are expanded, the production cost is reduced, and the production efficiency and the product quality are improved.

Description

technical field [0001] The present application relates to the technical field of non-woven fabric production, in particular to a three-carded spunlaced non-woven fabric with direct laying and a preparation method thereof. Background technique [0002] Spunlace non-woven fabric is one of the non-woven production methods, and its products are widely used in medical supplies, hygiene supplies, artificial leather base fabrics, clothing interlinings, decorative fabrics, etc. According to the different web forming methods, the spunlace nonwoven production line can be divided into direct laying spunlace nonwoven production line and cross laying spunlace nonwoven production line. [0003] The direct-laid spunlace nonwoven production line is a production line in which one or more carding machines are connected in series or parallel to output fiber webs into a fiber web of a certain thickness, and then output for subsequent spunlace reinforcement. The products obtained by this produc...
