American dry-laid non-woven fabrics refer to extruding and stretching polymers to form continuous filaments, then laying the filaments into a web, which is then self-bonded, thermally bonded, chemically bonded or mechanically reinforced. Method to turn the fiber web into non-woven fabric.
American dry-laid non-woven fabrics break through traditional textile principles and have the characteristics of short process flow, fast production speed, high output, low cost, wide range of uses, and multiple sources of raw materials. They are a new generation of environmentally friendly materials and are water-repellent. , breathable, flexible, non-combustible, non-toxic and non-irritating, rich in color, etc.
Non-woven fabrics are the youngest and most promising emerging field in the textile industry.
my country’s non-woven industry started late, but it is developing very rapidly.
Non-woven fabrics in the early stages of development were mainly used in the clothing industry as auxiliary materials.
With the rapid development of social economy and science and technology, new products and new technologies of non-woven fabrics are emerging one after another, changing with each passing day, and their application scope is becoming increasingly wider.
Suzhou ptfe filter membrane manufacturer supplies American dry-laid non-woven fabrics, which have good high temperature resistance (polypropylene can be used in an environment of 150℃ for a long time, polyester can be used in an environment of 260℃ for a long time), aging resistance, UV resistance, It has the characteristics of high elongation, good stability and breathability, corrosion resistance, sound insulation, moth-proof, and non-toxic.
In addition, its chemical properties are also very stable. The non-woven fabric has good chemical stability. In addition to being corroded by acids, it is relatively stable to various other chemical reagents, but low molecular weight aliphatic hydrocarbons and aromatic hydrocarbons It can soften and swell non-woven fabrics, and the chemical stability increases with the increase of crystallinity.
