More Information
Summary:The invention belongs to the field of spunbonded non-woven materials, and relates to preparation of superfine fibers, in particular to an improved spunbond device, a forming method and a split-releasetype double-component filament-based superfine fiber material. The method comprises the following steps of (1) preparing magnetic electret particles; (2) implementing a preparation process of split-release type protofilament; (3) implementing a procedure of fibrillating the two-component filament superfine fiber non-woven material to form a net; (4) implementing a brooming three-resistance finishing process of the two-component filament superfine fiber non-woven material; and (5) carrying out a corona-annealing electret process of the two-component filament superfine fiber non-woven material,so as to finally obtain the two-component filament superfine fiber non-woven material with strength, flexibility and medical protection characteristics. The method has the characteristics of environmental protection and relia
