Abstract

The invention relates to a silk / ES non-woven material with a semi-open pore structure and a preparation method thereof. The non-woven material is composed of two layers of fiber nets, and the fibers of the two layers are combined by hydroentangling. The fibers on the surface layer have holes, and the fibers on the bottom layer Without holes, a semi-open cell structure is formed. The preparation method includes: sending silk fibers into a cotton storage box, loosening, dissociation, mixing and opening until uniform, and then carding and laying to obtain a surface silk fiber web; the ES fibers are opened, carded, laid, Hot air bonding and reinforcement to obtain the bottom fiber web; spread the surface silk fiber web on the bottom fiber web, and enter the spunlace unit together, after spunlace forming, dehydration, hydrophilic treatment, drying, winding, shearing treatment, that is, . The nonwoven material prepared by the invention has a semi-open pore structure, high utilization rate of silk, short water penetration time and small reverse osmosis amount.

Description

technical field [0001] The invention belongs to the field of preparation of nonwoven materials, in particular to a preparation method of silk / ES semi-open pore structure nonwoven materials. Background technique [0002] Silkworms cannot be exposed to any pesticides or harmful chemicals during the whole growth process. The silk fiber is thin and soft. The ingredient silk peptide contains 18 kinds of amino acids that are beneficial to the human body. It has strong compatibility with human skin and less irritation (stimulation to the skin) Coefficient of only 7.4%, while polyester is 25.5%), known as the "fiber queen", so silk is often regarded as the most "green" environmentally friendly fiber. In recent years, the pure natural products developed by some companies - silk needle-punched non-woven fabrics and silk spunlace non-woven fabrics are particularly eye-catching. This product has changed the single purpose of silk as clothing, and it can also be widely used It is used i...
