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.

Description

technical field [0001] The invention relates to the field of nonwoven fabrics, in particular to a nanofiber modified ultra-soft nonwoven fabric and a manufacturing method thereof. Background technique [0002] At present, non-woven technology is a relatively young and promising new technology in the textile industry. Non-woven fabrics have quickly penetrated into the national economy due to their unique structure, changeable technology and other incomparable advantages of traditional textiles. various fields of application. Especially in the field of medical and health care, nonwovens have a very broad space for development. [0003] Non-woven fabric is composed of directional or random fibers. It is a new generation of environmentally friendly materials. It is moisture-proof, breathable, flexible, light in weight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color, low in price, and recyclable. Features such as reuse. [0004] Single-layer no...
