随着微细纤维的用途增加(如纤维素醋酸酯纤维在高精度微粒子滤器中的使用)和新材料的不断涌现(如纤维合成材料),微细喷丝头的用量也不断的增加。现今使用的喷丝头主要由金属材料制成,依照用途的特殊性,采用CNC侵蚀工艺和钻切加工技术将喷丝孔制成一定的几何形状。精密喷丝头的高级别的质量标准主要是指:在多次重复使用的情况下,喷丝孔内壁的粗糙度及出口边缘的锐度和
With the increasing use of microfibers (such as the use of cellulose acetate fibers in high-precision particulate filters) and the continual emergence of new materials (such as fiber composites), the amount of fine spinnerets has also been steadily increasing. The spinneret currently used is mainly made of a metal material, and according to the particularity of use, the spinneret hole is formed into a certain geometric shape by a CNC erosion process and a drilling and cutting process. The high level of precision spinneret quality standards mainly refers to: in the case of repeated use, the inner wall of the spin hole roughness and the sharpness of the edge of the exit and
