With the continuous improvement of non-woven processing technology, there are more and more types of non-woven fabrics, and the quality is getting better and better, and the application of non-woven fabrics in various industries is becoming more and more extensive. Although there are many, each non-woven fabric has its advantages and disadvantages. This article mainly introduces the classification of different types of non-woven fabrics and the industrial application of different types of non-woven fabrics in detail.
Classification of different types of non-woven fabrics:
Non-woven fabrics break through the traditional textile principle, and have the characteristics of short process flow, fast production speed, high output, low cost, wide application, and many sources of raw materials. It is a new generation of environmentally friendly materials. Combustion-supporting, non-toxic and non-irritating, rich in color and so on.
The fibers used in the production of non-woven fabrics are mainly polypropylene (PP) and polyester (PET). In addition, there are nylon (PA), viscose, acrylic, ethylene (HDPE), and vinyl (PVC).
According to the application requirements: non-woven fabrics are divided into two categories: disposable application type and durable type.
According to the production process is divided into:
1 Spunlace non-woven fabric: The spunlace process is to spray high-pressure fine water flow onto one or more layers of fiber webs, so that the fibers are entangled with each other, so that the fiber webs can be reinforced and have a certain strength.

It uses the air-laid technology to open the wood pulp fiberboard into a single fiber state, and then uses the air-laid method to condense the fibers on the web-forming curtain, and the fiber web is then reinforced into a cloth.
4 Wet-laid non-woven fabric: Wet-laid non-woven fabric is to open the fiber raw materials placed in the water medium into single fibers, and at the same time mix different fiber raw materials to make fiber suspension pulp. In the wet state, it is formed into a web and then reinforced into a cloth.
5 Spunbond non-woven fabric: Spunbond non-woven fabric is after the polymer has been extruded and stretched to form continuous filaments, the filaments are laid into a web, and the fiber web is then self-bonded, thermally bonded, chemically bonded. Combination or mechanical reinforcement methods to turn the web into a non-woven fabric.
6 Melt-blown non-woven fabric: The process of melt-blown non-woven fabric: polymer feeding---melt extrusion---fiber formation---fiber cooling---forming web---reinforcing into cloth. Industry applications of different types of non-woven fabrics.
7 Needle-punched non-woven fabric: Needle-punched non-woven fabric is a kind of dry-laid non-woven fabric. Needle-punched non-woven fabric uses the puncture effect of a needle to reinforce the fluffy fiber web into cloth.
8 Stitch-bonded non-woven fabrics: Stitch-bonded non-woven fabrics are a kind of dry-laid non-woven fabrics. foil, etc.) or a combination thereof to be reinforced to make a non-woven fabric.
9 Hydrophilic non-woven fabrics: mainly used in the production of medical and sanitary materials to achieve better hand feel and not scratch the skin. For example, sanitary napkins and sanitary pads use the hydrophilic function of hydrophilic non-woven fabrics.
Industry applications of different types of non-woven fabrics:
Geosynthetics is a high-tech, high value-added industrial textile material with a wide range of uses. Nonwoven geotextiles mainly include: spunbond geotextiles, staple fiber needle punched geotextiles, hot melt bonded geotextiles, geonets and grids, geomembranes, and composite geotextiles. Geotextiles have the functions of reinforcement, isolation, filtration, drainage and anti-seepage in geotechnical construction.
2. Non-woven filter media
