Hot rolling is the last web forming technology in the production process of non-woven fabrics, which is the process of cooling and laying the silk to form the fabric, Hot rolling has a high degree of heat (100~150 degrees · The rolling wheel rolls over uniform fibers to melt and form a mesh, so there will be rolling points on the surface of the hot-rolled non-woven fabric, similar to pinholes, but not penetrating. The specific size depends on the size and density of the steel spikes on the rolling wheel.

It is not difficult to conclude that as a process, hot-rolled non-woven fabric is not a specific type of fabric, but a general term for a type of non-woven fabric that has undergone similar processes. Generally speaking, hot-rolled non-woven fabric is used The treatment process involves spunbonded polypropylene non-woven fabric (PP.), polyester non-woven fabric (PET.), and PA nylon (PA.). The biggest difference among these three types is the difference in processing raw materials.
