Hydrophilic non-woven fabric

What is a hydrophilic non-woven fabric

Most of the non-woven fabrics themselves are not hydrophilic or directly water-repellent. In order to make the non-woven fabric achieve the hydrophilic function, a hydrophilic agent is added in the production process of the non-woven fabric, or a hydrophilic agent is added to the fiber during the production of the fiber, which is called a hydrophilic non-woven fabric.

The purpose of adding hydrophilic agent

Fibers or non-woven fabrics are high-molecular polymers with few or no hydrophilic groups themselves, so they cannot achieve the hydrophilic properties required in the application of non-woven fabrics, so a hydrophilic agent is added.

performance
Non-woven fabrics are 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. The material can be naturally decomposed when placed outdoors for 90 days, and has a service life of up to 5 years when placed indoors.

1. Light weight: Polypropylene resin is used as the main raw material for production, with a specific gravity of only 0.9, only three-fifths of cotton, with fluffy and good hand feeling.

2. Non-toxic and non-irritating: The product is produced with FDA food-grade raw materials, does not contain other chemical components, has stable performance, is non-toxic, has no peculiar smell, and does not irritate the skin.

3. Antibacterial and anti-chemical agents: Polypropylene is a chemically passive substance, not moth-eaten, and can isolate the erosion of bacteria and insects in the liquid; antibacterial, alkali corrosion, and finished products do not affect the strength due to erosion.

4. Good physical properties. It is made of polypropylene spun directly into a mesh and thermally bonded. The strength of the product is better than that of ordinary staple fiber products. The strength is non-directional, and the vertical and horizontal strengths are similar.

5. In terms of environmental protection, the raw material of most of the non-woven fabrics used is polypropylene, while the raw material of plastic bags is polyethylene. Although the two substances have similar names, they are quite different in chemical structure.

use
Mainly used in the production of medical and sanitary materials to achieve a better feel and not scratch the skin. For example, sanitary napkins and sanitary pads use the hydrophilic function of hydrophilic non-woven fabrics.

Prospect Analysis
In recent years, the growth rate of world nonwoven demand has always been higher than that of the global economy. Global non-woven production is mainly concentrated in the United States, accounting for 41% of the world total, Western Europe 30%, Japan 8%, China 3.5%, and other regions 17.5%. Among the terminal applications of non-woven fabrics, sanitary absorbent (especially diapers) products have the fastest growth, and medical textiles, automotive textiles, footwear and artificial leather markets also show a new atmosphere of rapid development.

China's non-woven industry started relatively late, but it has developed rapidly. In the early 1980s, production was less than 10,000 tons. In the mid-to-late 1990s, China set off an upsurge in the development of non-woven products. In addition to using domestic production lines, Guangdong, Zhejiang, Jiangxi, Hunan and other provinces have also introduced production lines from abroad. The development speed of China's non-woven products greatly exceeds the average development speed of the textile industry, with an annual growth rate of 8-10%, which is the fastest growing industry in the textile industry.
