Imported spunbond non-woven fabrics are made by extruding and stretching polymers to form continuous filaments. The filaments are laid into a web, and the web is then self-bonded, thermally bonded, chemically bonded or mechanically reinforced. , turning the fiber web into non-woven fabric.
It has good high temperature resistance, good low 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, high elongation, stability and breathability Good, corrosion-resistant, sound-insulating, moth-proof and non-toxic.
?The main imported spunbond non-woven fabric technologies in the world include Leifen’s Lecofer technology from Germany, STP technology from Italy, and Kobe Steel technology from Japan.
The current situation, especially Leffen technology, has become the mainstream technology in the world.
It has now developed to the fourth generation technology.
The characteristic is that it adopts negative pressure ultra-high-speed air drafting, and the fiber can be stretched to about 1 denier.
Many companies in China have already imitated it. Since its core technology has many cutting-edge issues that have not yet been solved or mastered, it will take some time for domestic equipment manufacturing companies to reach the level of Laifen technology.
Suzhou New Material Technology Co., Ltd. is a manufacturer specializing in the research, development and production of polytetrafluoroethylene materials. After years of painstaking research and development, the company not only has strong research and development capabilities, complete testing methods and domestically advanced Experimental equipment has also attracted a large number of outstanding technical talents.
