Spunlaid, or spunbond nonwovens, can be manufactured in a continuous process. In the process, the fibers used are primarily spun, and then with the help of deflectors, they are spread on a sheet. Spunbond is comparatively a faster way of producing polymer nonwovens as the technique results in faster belt speeds and manufactures low-cost products.
The nonwoven materials manufactured using the meltdown technique have lower intrinsic strength than the spunbond. Consequently, the melt-blown fabrics are mixed with the spunbond fabrics to produce much stronger and more resilient nonwoven products through the technique of spun-melt-spun, also called SMS fabrics. These fabrics, made with polypropylene , are waterproof and can be utilized for use-and-throw purposes.
