Hot rolling is the last web forming technology in the production process of non-woven fabrics, which is a process of cooling and laying the fibers to achieve the fabric. Hot rolling has high heat (100-150 degrees · rolling wheel uniformly rolls the fibers to melt and form a web). Generally speaking, the hot rolling process is used for spunbond polypropylene non-woven fabric (PP), polyester non-woven fabric (PET), PA nylon (PA). The biggest difference between these three types is the difference in processing raw materials. Hot rolling non-woven fabric equipment is equipped with electromagnetic heating rollers, which can save more than 60% energy, improve line speed, and greatly improve productivity. About 100m of fabric is produced per minute. Hot rolled non-woven fabric with the same weight has higher tensile strength, tear, burst, tensile strength, etc. than needle punched non-woven fabric. Several tens of times larger.
