Embodiment Construction

[0034] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0035] see figure 1 , shown in the figure is a non-woven fabric with partially water-repellent treatment on the surface of the present invention, including a substrate layer 100 with a hydrophilic function, and a surface 101 of the substrate layer 100 is partially treated with water A partial water-repellent area 102 is formed on 101 . The partially water-repellent region 102 occupies 1%-90%, preferably 10%-50%, of the total area of ​​the surface 101 of the substrate layer 100 .

[0036] A kind of preparation method of the present invention is used to prepare the non-woven fabric that the surface has undergone local water-repellent treatment, comprises the following steps:

[0037] Step S1, preparing a substrate layer 100 with a hydrophilic fu...

Abstract

The invention discloses a non-woven fabric with a surface subjected to local water repellency treatment. The non-woven fabric comprises a base material layer used as a surface layer of a heath care product, and after one surface of the base material layer is subjected to local water repellency treatment, a local water repellency region is formed on the surface. The invention further discloses a preparation method and application of the non-woven fabric. The surface of the non-woven fabric is subjected to local water repellency treatment, the water retention rate of the non-woven fabric used as the surface layer or the contact area between the non-woven fabric and skin is adjusted by adjusting the area ratio of a hydrophilic region to the water repellency region, therefore, the use experience is improved, and experience comfort is enhanced.

Description

technical field [0001] The invention relates to the technical field of non-woven fabrics used in sanitary care products, in particular to a non-woven fabric whose surface has undergone partial water-repellent treatment and its preparation method and application. Background technique [0002] Non-woven fabric (English name: Non Woven Fabric or Nonwoven cloth), also known as non-woven fabric, is composed of oriented or random fibers. It is a polymer fiber base cloth material produced by a non-woven process. Light weight, low cost, recyclable and so on. Common nonwoven processes include: spunbond process, melt blown process, hot air process, hot rolling process, spunlace process, etc. Commonly used fibers include artificially synthesized polymer fibers (such as PP, PE, PET, PA, etc.) and natural fibers (such as cotton fibers, viscose fibers, chitin fibers, bamboo charcoal fibers, etc.). [0003] Non-woven fabrics are used as absorbent products, such as: sanitary napkins / pads,...
