The utility model relates to an acrylic spinneret, which is composed of an upper cover body, a lower cavity and a spinneret tube. The upper cover body sits at the opening of the lower cavity, and an outlet is arranged at the bottom of the lower cavity. The spinneret tube comprises a coarse spinneret tube and a fine spinneret, and the coarse spinneret tube and a fine spinneret tube are obliquely inserted through the upper cover body and extended into the lower cavity for coarse spinning. The outlet end of the filament pipe and the fine spinneret are connected with the outlet pipe. An outlet is arranged at the bottom of the lower chamber. The outlet pipe is protruded from the outlet. The inner diameter of the outlet is larger than the outer diameter of the outlet pipe. A liquid inlet pipe is arranged on the side wall of the lower chamber. The double tube design of the utility model can make the spurted acrylic fibers form a thick double fiber structure. Because the two fibers are in high temperature when contacting, the two fibers fuse into a whole. When the temperature of the two fibers is lowered, the two fibers shrink to form a helical structure. The structure has good toughness, good elasticity and wide application range. At the same time, a functional outer layer is formed on the outer wall of the two fibers, which increases the functionality of the fiber.

一种腈纶喷丝板
本技术涉及喷丝板,尤其涉及一种腈纶喷丝板。
技术介绍
腈纶是一种应用广泛的化学纤维,腈纶的内部结构决定了柔韧度和弹性等物理性质,而为了使腈纶具有特殊的功能,例如耐高温、防水、防静电等功能,普遍是将已经成型的腈纶表面涂覆目标涂层,以达到其需要的功能,而这种方法在工艺过程中会进行二次加热,一次是在腈纶定型时进行升温,当腈纶冷却定型后,进行涂层涂覆时,需要二次加温,极大的浪费了热能,造成能源的浪费。
技术实现思路
本技术对于上述现有技术的不足,提供了一种腈纶喷丝板。本技术的一种腈纶喷丝板,是由上盖体、下腔和喷丝管构成,所述的上盖体坐于下腔体的开口处,下腔体的底部设有出口;喷丝管包括粗喷丝管和细喷丝管、且粗喷丝管和细喷丝管斜插穿过上盖体、并伸入下腔体内,粗喷丝管和细喷丝管的出口端均与出口管相连,下腔体的底部设有出口,出口管由出口伸出,出口的内径大于出口管的外径,下腔体的侧壁设有进液管。作为本技术的进一步改进,所述的粗喷丝管的管径大于细喷丝管的管径。作为本技术的进一步改进,所述的出口为锥形。本技术的一种腈纶喷丝板,其粗喷丝管和细喷丝管的双管设计,能够使喷出的腈纶 ...
