Abstract

The invention relates to a dispersible full-degradable spunlaced nonwoven fabric and a preparation method thereof, and belongs to the technical field of nonwoven fabric materials. The spunlaced nonwoven fabric is prepared from the following raw materials in percentage by weight: 15-30 percent of viscose, 5-10 percent of tencel and the balance of wood pulp. The dispersible full-degradable spunlaced nonwoven fabric has good dispersing performance and high strength, and the preparation method of the spunlaced nonwoven fabric has the advantages of short process flow, low defective percentage and high production efficiency; and the spunlaced nonwoven fabric is wide in raw material source, has various varieties, high yield and wide application range, and is environment-friendly.

Description

Technical field [0001] The invention relates to a flushable fully degradable spunlace non-woven fabric and a preparation method thereof, and belongs to the technical field of non-woven fabric materials. Background technique [0002] With the enhancement of environmental protection awareness, flushable fully degradable spunlace non-woven fabrics have appeared in the field of spunlace non-woven fabrics. However, the flushability of this kind of spunlace non-woven fabric currently on the market needs to be further improved, and its production process also needs to be further optimized. Summary of the invention [0003] The purpose of the present invention is to provide a flushable fully degradable spunlace nonwoven fabric and a preparation method thereof. The flushable fully degradable spunlace nonwoven fabric has good flushing performance and high strength, and the flushable fully degradable spunlace The preparation method of the thorn non-woven fabric has short process flow, low d...
