It is understood that the rapid development of the domestic chemical fiber industry has provided considerable raw material support for the rapid development of nonwovens. Driven by domestic demand, it also brings development opportunities to the High-efficiency and low-resistance spunbond non-woven fabric industry.
In order to improve the performance of nonwoven fabrics, it is also necessary to stretch and orient the virgin fibers to increase the orientation and crystallinity of the fibers, thereby improving the physical and mechanical properties of the fibers. In the production of spunbonded nonwovens, since the subsequent processes such as spinning, drawing, splitting, laying, and reinforcement are continuous and high-speed, the fiber stretching is completed in a very short time, and the fiber needs to be It provides ideal cooling effect, so the production of spunbond nonwovens mostly uses air flow stretching.
High-efficiency low-resistance spunbond non-woven fabrichas high strength, high temperature resistance (can be used for a long time in an environment of 150℃), aging resistance, UV resistance, high elongation and stability It has the characteristics of good sex and breathability, corrosion resistance, sound insulation, moth-proof, and non-toxic. It also has good chemical stability. In addition to being corroded by acids, it is relatively stable to various other chemical reagents. However, low molecular weight aliphatic hydrocarbons, aromatic hydrocarbons, etc. can soften and swell non-woven fabrics. The chemical stability varies with the degree of crystallinity. The increase has also improved.
