Abstract

The invention relates to non-woven techniques, and discloses a bamboo pulp dispersible spunlace material and a production method thereof. The bamboo pulp dispersible spunlace material is prepared from, in weight percentage, 10-80% of bamboo pulp, 0-60% of wood pulp and 10-60% of man-made cellulose fibers by the aid of a wet-laying spunlace entanglement process, and the gram weight of the bamboo pulp dispersible spunlace material is 40-80g / m<2>. The production method includes the steps: 1) performing repulping and millstone grinding to obtain pulp mixed liquid; 2) adding the man-made cellulose fibers to prepare fiber mixed pulp; 3) forming an inclined net, and performing pre-spunlacing and secondary dehydration; 4) performing spunlacing, pumping and drying. The bamboo pulp dispersible spunlace material is prepared from selected special materials by the aid of a special wet spunlace non-woven process and can solve the problem of reduction of dispersion property caused by the action of wet tissue essence in the post-processing process, raw materials are easily obtained, and production cost is low.

Description

technical field [0001] The invention relates to a flushable nonwoven material, in particular to a bamboo pulp flushable spunlace material applied to personal hygiene care products and a manufacturing method thereof, belonging to the technical field of flushable spunlace nonwovens. Background technique [0002] Due to a series of environmental protection problems brought about by the popularization of disposable personal care products, domestic and foreign companies have been very active in research and exploration in the field of flushable nonwoven materials in recent years. At present, there are two main technical directions in the study of flushable nonwoven materials: one is to use specific or modified binders to achieve water flushability; the other is to specialize and differ in raw materials and processes Chemicalization, that is, the selection of raw materials and process methods with special fiber structure to make the obtained non-woven fabric untangle and disperse ...
