纺粘无纺布时将聚合物挤出、拉伸，形成连续长丝后，长丝铺设成网，纤网再经过自身粘合、热粘合、化学粘合或机械加固方法，使纤网变成无纺布。

When spunbonded nonwoven fabric is extruded and stretched to form continuous filament, the filament will be laid into mesh, and then the mesh will be transformed into non-woven fabric through self bonding, thermal bonding, chemical bonding or mechanical reinforcement.

耐高温性能好、耐高温性能好（丙纶可在150℃环境中长期使用、涤纶可在260℃环境中长期使用）、耐老化、抗紫外线、延伸率高、稳定性和透气性好、耐腐蚀、隔音、防蛀、无毒。

High temperature resistance and good high temperature performance (polypropylene can be used for a long time, 150 degrees in the environment of polyester used for a long time at 260 DEG C), anti-aging, anti UV, high elongation, stability and good air permeability, corrosion resistance, sound insulation, non-toxic, anti moth.
