Abstract

The invention discloses a fully degradable polylactic acid fiber spunlace fabric and a preparation method thereof. The spunlace fabric with the thickness of 0.2-1.2mm is prepared by adopting polylactic acid fiber with the fineness of 0.6-1.2dtex and the length of 25-72mm to perform crossing and netting, spunlacing and tangling and drying. The polylactic acid fiber spunlace fabric of the inventionhas high absorptivity, good air permeability and other good performances, and is fully natural without skin irritation and allergic reaction, thus being applicable to the production of the surface material of baby care products and female care products. The preparation method of the invention has simple and practical process, thus being applicable to industrialized production.

Description

technical field

[0001] The invention belongs to the field of textiles, and in particular relates to a spunlace nonwoven fabric made of fully degradable polylactic acid fibers and a preparation method thereof. Background technique

[0002] In the prior art, common spunlace non-woven fabrics are made of chemical fiber materials, which can cause irritation and allergies after contact with the body, and the water absorption and air permeability are not ideal.

[0003] With the strengthening of social environmental awareness, the development and application of biodegradable polymers has attracted great attention. Polylactic acid (PLA) is a representative of chemically synthesized biodegradable lipopolyester. It has good biocompatibility and safety, is non-toxic and harmless to the human body, and gradually degrades in the body and in the natural environment, and finally becomes carbon dioxide and water. In addition, the monomer of polylactic acid is lactic acid, which is fermen...
