Problems solved by technology

However, this kind of fluffy area is a fibrous network raised structure formed by the aggregation of fibers. Compared with the true fluffy area, this kind of raised fiber has less pore space, and the ability to accommodate essence or solid particles is not strong. And the feel is relatively hard, the ductility is poor, and it is still not close enough to the skin
In addition, under this processing method, higher spunlace pressure is required, and the production energy consumption is 1.2 to 1.5 times that of conventional plain spunlace products.

Abstract

The invention relates to the technical field of non-woven material and discloses alternating interval spunlaced nonwoven material and a preparation method thereof. The alternating interval spunlaced nonwoven material comprises a fiber net. The fiber net is formed in such a manner that the fiber net is carded by a single-layer or multi-layer mutually-overlapping dry method and reinforced by transverse interval spunlace. Multiple high tangling areas and non-tangling areas / low tangling areas are formed on the surface of the fiber net by transverse interval spunlace reinforcement. The high tangling areas and non-tangling areas / low tangling areas are distributed at intervals along a transverse direction and mutually connected. The fiber entanglement degrees in the high tangling areas are higherthan those in the low tangling areas. Fibers in the non-tangling areas do not tangle. The surface of the alternating interval spunlaced nonwoven material is equipped with a fluffy area with sufficient pore spaces. The fluffy area has the capability of accommodating liquid and solid particles. The alternating interval spunlaced nonwoven material has good flexibility, ductility and skin-affinity.

Description

Technical field [0001] The invention relates to the technical field of non-woven materials, in particular to an alternately spaced spunlace non-woven material and a preparation method thereof. Background technique [0002] Spunlace non-woven material is a non-woven fabric obtained by mechanically carding the fibers into a web, and then through the jet of high-pressure fine water jets to make the fibers intertwined and entangled, so that the fiber web can be reinforced and have a certain strength. Spunlace nonwoven materials are characterized by soft hand feeling and certain breaking strength, and are mostly used in application fields such as sanitary care, civil cleaning, medical sanitary materials and so on. [0003] CN201710046779.4 discloses a preparation method of environmentally friendly spunlace non-woven fabrics, which includes the following steps: mixing high moisture absorption modified polyester fiber and spunlace special viscose fiber, opening and mixing, and the first, ...
