Title:
EXTRA-SOFT NONWOVEN FABRIC MADE OF MODIFIED NANOFIBER AND MANUFACTURING METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2018/032624
Kind Code:
A1
Abstract:
An extra-soft nonwoven fabric made of a modified nanofiber comprises the following layers sequentially stacked from bottom to top: a base layer; a hydrophilic layer bonded to the base layer; an anti-microbial layer bonded to the hydrophilic layer; and a soft modified nanofiber layer bonded to the anti-microbial layer, the soft modified nanofiber layer being formed by mixing polypropylene, a nano-elastic body and a soft masterbatch and performing fusion, silk-spinning, and a composite nonwoven process on the mixture. Multiple pattern units are uniformly arranged at a surface of the soft modified nanofiber layer away from the base layer. Each pattern unit comprises a first recess and a second recess. The first recess is proximate to the second recess. The first recess has a circular cross-section. The second recess has an S-shaped cross-section. The invention is softer and fluffier, has higher water-absorbing capacity, water-retaining capacity and anti-microbial capacity, and exhibits good hand feel. Also provided is a manufacturing method of the above extra-soft nonwoven fabric made of a modified nanofiber.
