Problems solved by technology

[0004]However, most of the non-woven materials on the market are light, thin and soft, and their water retention and strength are limited, so they cannot fully play the role of cosmetic liquid carrier. Efficacy, and also to improve the water retention of the product to increase the weight of the product, but the softness of the product can not be guaranteed
[0005]In addition, the film cloth products on the market now are more highly respected for adhesion, however, most of them use ordinary fibers with larger deniers to make film cloth, and the obtained film cloth The adhesion of the film cloth is low, so the adhesion of the film cloth needs to be improved
[0006] For example, a softer non-woven fabric is disclosed in the Chinese published patent CN103660416A, which is made by using softer soybean fiber and other raw materials. Due to the excellent performance of the fiber, the non-woven material has a certain soft style, but the raw material cost of the product with this structure is high, and the product function is single. Generally, it is not a very ideal non-woven material for skin care and cleaning, and it cannot be widely used.

Abstract

The invention discloses a non-woven laminated cloth. The non-woven laminated cloth comprises nano-fiber layers and a special-shaped section fiber layer, wherein each nano-fiber layer at least containsnano-fibers with an average diameter of 150-450 nm, the special-shaped section fiber layer at least contains special-shaped section fibers with the multi-leaf structure section, and the nano-fiber layers are on the surfaces of the nonwoven laminated fabric. The non-woven laminated fabric has the characteristics of good softness, high water retention rate, and good adherence property, and can be widely used in the field of skin care and sanitary cleaning materials.

Description

technical field [0001] The present invention relates to a nonwoven laminated fabric. Background technique [0002] Due to the characteristics of short production process, low cost and wide application, nonwoven materials have gradually become an indispensable material in people's daily life. At the same time, with the continuous advancement of non-woven material technology, the market pays more and more attention to the performance of non-woven material itself. [0003] In recent years, the functions of skin care and cleaning products have been continuously diversified, and the market demand has continued to increase. The market for skin care and cleaning products has shown explosive growth. At present, China has the world's largest market for skin care masks and cleaning and hygiene products. Due to the continuous enhancement of people's awareness of skin care, there are more and more requirements for clean skin care materials in the market, and various functional products...
