As a new generation of environmentally friendly materials, PET spunbond non-woven fabric has the advantages of short process flow and high production speed. Therefore, it can be used in many fields, including building materials, geotechnical materials, etc., and is sustainable for mankind. development has made significant contributions.
The application of geotextiles abroad began as early as the 1960s. The United States is the country with the largest consumption of geotextiles in the world. In the early 1990s, its annual consumption was more than 300 million m2. In recent years, the usage Reaching 700 million m2.
Geotextiles in Europe and Japan have also developed rapidly. The annual consumption of geotextiles in Europe in recent years has also been around 400 million m2, of which spunbond nonwovens account for about 60% of nonwoven geotextiles; in Japan, The application of geotextiles has grown significantly since the mid-1990s.
The spunbond method is the most used in Japanese nonwoven geotextiles, accounting for about 60% of the total nonwoven geotextiles, and it is mainly PET spunbond nonwoven fabrics.
Suzhou ptfe filter membrane manufacturer supplies imported wet-laid non-woven fabrics. After the polymer is extruded and stretched to form continuous filaments, the filaments are laid into a network, and the fiber network is then self-bonded, thermally bonded, Chemical bonding or mechanical reinforcement methods turn the fiber web into a non-woven fabric.
Pet spunbond non-woven fabric has good high temperature resistance and low temperature resistance (polypropylene can be used for a long time in an environment of 150℃, polyester can be used for a long time in an environment of 260℃), aging resistance, UV resistance, high elongation, Good stability and breathability, corrosion resistance, sound insulation, moth-proof, and non-toxic.
