Modified aramid fiber and processing technology thereof

Abstract

The invention belongs to the technical field of modified aramid fiber, and particularly relates to modified aramid fiber and a processing technology thereof. A washing device comprises a supporting frame; a motor is fixedly connected to the end face of the right side of the supporting frame; a washing box is rotationally connected to the interior of the inner wall of the supporting frame through arotating pipe; the rotating pipe is fixedly connected with a driving shaft of the motor; a liquid storage box is fixedly connected to the end face of the left side of the supporting frame; the liquidstorage box is rotationally connected with the washing box through a guide pipe; and supports which are uniformly arranged are fixedly connected to the outer surface of the rotating pipe and locatedin a cavity of the washing box. The modified aramid fiber and the processing technology thereof are mainly used for solving the problems that in the modification process of aramid fiber on the marketat present, often, active groups are introduced into the aramid fiber for modification by adopting various chemical stock solutions, but the modification mode is long in technological process, the modification technology is relatively complex, meanwhile, some existing aramid fiber washing devices need long time, the aramid fiber is not washed thoroughly, and fiber filaments are easy to diffuse everywhere in the process of washing the fiber filaments by some washing devices.

Description

technical field [0001] The invention belongs to the technical field of modified aramid fibers, in particular to a modified aramid fiber and its processing technology. Background technique [0002] Aramid 1414 is currently the world's largest organic fiber with high modulus, high strength, high temperature resistance, acid and alkali resistance, and light weight. The specific strength is 5-6 times that of steel wire, the specific modulus is 2-3 times that of steel or glass fiber, the toughness is 2 times that of steel, and the weight is only 1 / 5 of steel. It is widely used in the fields of national defense, aerospace, information industry, body armor, soil construction, sealing packing, etc., and has the reputation of "synthetic steel wire". Aramid fiber is a general term for aromatic polyamide fibers. According to different chemical structures, aramid fiber can be divided into para-aramid fiber (MPIA) and para-aramid fiber (PPTA). The amide on the para-aramid molecular stru...

Problems solved by technology

[0006] In order to make up for the deficiencies of the prior art, the present invention proposes a modified aramid fiber and its processing technology. To introduce active groups into the aramid fiber for modification, however, this modification method has a long process and the modification process is relatively complicated. At the same time, some existing aramid washing devices put aramid fiber cloth into the washing device However, the process of washing fibers in this way often takes a long time, and the washing of aramid fibers is not thorough. Some of them put aramid fiber filaments into the washing device for washing. However, using this method in In the process of washing aramid fiber, aramid fiber is easy to spread everywhere, so that the aramid fiber is not easy to collect
