Polyester-wood pulp wet process spunlace material

Abstract

The invention relates to a spunlace material which is processed and formed by adopting polyester ultra-short fibers and wood pulp as main raw materials through a wet process spunlace technology. The material is prepared by mixing 10%-80% by weight of polyester ultra-short fibers, 0%-5% by weight of reinforced ultra-short fibers and 15%-90% by weight of wood pulp subjected to grinding, devillicate and brooming. A forming method of the material comprises the steps that the wood pulp is pulped and then subjected to devillicate and brooming, the polyester ultra-short fibers and the reinforced ultra-short fibers are unpacked and then subjected to liquid-phase dispersion, and the three liquid phases are mixed, subjected to wet forming and then subjected to pre-spunlace, spunlace, suction, drying, stain detection, rolling after gram weight detecting, slitting and packaging on an inclined-wire forming net. The material has the advantages that the milled wood pulp is subjected to devillicate and brooming, so that higher hydrogen bonding is formed among wood pulp fibers to solve the high cohesive force problem caused by length limitation; viscose is replaced with the wood pulp, the water absorption performance of the material used as a wet tissue material is guaranteed, and the raw material cost is greatly reduced.

Description

technical field [0001] The invention relates to a spunlace material which uses polyester ultra-short fiber and wood pulp as main raw materials and is processed and formed through a wet spunlace process. It is mainly used as a sanitary material and belongs to the field of spunlace nonwoven material manufacturing. Background technique [0002] CN104562831 A. Name "fully degradable skin-friendly high-soft fine denier cellulose spunlace wet tissue material and wet tissue manufacturing method", consisting of 10-80% of 5-15mm cellulose fiber with a fineness of less than or equal to 0.9 decitex and 90-20% The ratio is made by mixing wood pulp that has been refined and separated. Its production method, (1) According to the weight ratio of 1:3‰-1:7‰, the 5-15mm cellulose fiber raw material with a fineness less than or equal to 0.9 decitex is opened and discharged into the water in the fiber pool for lateral Propel and stir to make the cellulose fiber and water evenly stirred, and th...

Problems solved by technology

[0003] Although the wet spunlace materials produced by the above existing technologies can be fully degraded, compared with the traditional dry spunlace materials, the breaking strength of the materials is lower, which cannot meet the needs of customers who have requirements for the breaking strength of the materials.
