由于新技术的发展,目前已能制造纤维在整个纤维层厚度的中央相互粘结的填料产品,而不再像以往那样纤维只粘结在纤维层的表面了。杜帮公司已研究成一种能使热熔性纤维均匀分布的加工方法;所用热熔性纤维的熔点低于普通聚酯纤维的熔点,当进行热处理时,这些热熔性纤维很快就均匀地相 Due to the development of new technologies, it has so far been possible to produce fillers in which the fibers are bonded to each other at the center of the entire thickness of the fiber layer, and the fiber is no longer bonded to the surface of the fiber layer as in the past. Du Bang Company has researched a processing method that can uniformly distribute hot-melt fibers; the melting point of the heat-melting fibers used is lower than that of ordinary polyester fibers. When the heat treatment is performed, these hot-melt fibers quickly and uniformly. phase
