The invention belongs to the technical field of aramid fiber production, in particular to the aramid fiber soaking device, which in turn includes the oil lifting platform and the extrusion roll. The extrusion roll includes a pair of upper and lower rollers, the shaft of the roller is installed horizontally, the roller surface of the one pair is fitted to each other; the extrusion roll is set in the rear order position of the oil platform; the oil is added to the oil platform. The platform comprises an oil injection mechanism and an oil soaking mechanism. The outlet of the oil injection mechanism is directed to the oil soaking mechanism, the oil soaking mechanism includes the oil soaking box, the oil in the oil soaking box, and a pair of roller in the oil soaking box, the surface of the roller is covered with a sponge, the shaft of the roller is vertically mounted on the dip. The oil tank and the lower part of the sponge are immersed under the oil level, and the sponges of one pair of rollers are attached to each other. The aramid fiber oil immersion device provided by the invention is combined with the oil injection mechanism and the oil immersion mechanism in two ways to improve the uniformity of oil feeding.

技术介绍
对位芳纶(PPTA)纤维是一种高性能芳香族聚酰胺纤维,由美国杜邦(DuPont)公司20世纪60年代成功开发并在70年代率先产业化,化学名称为聚对苯二甲酰对苯二胺(PPTA),商品名Kevlar,中国称之为芳纶1414。对位芳纶(PPTA)纤维属于国家三大高性能纤维材料之一,被称为“王牌纤维”,具有超高强度、高模量和耐高温、耐酸碱、质量轻、耐疲劳等优异性能,其强度是钢丝的5~6倍,模量为钢丝或玻璃纤维的2~3倍,韧性是钢丝的2倍,而重量仅为钢丝的1/5左右,在560℃的温度下不分解不融化,具有优异的耐高温性能。因此被广泛应用在先进复合材料、防护材料、橡胶增强材料、缆绳和光缆、建筑结构加固材料、航空航天材料等。然而芳纶纤维在紫外光照射下,特别是280~320nm范围的紫外光照射下易发生光老化降解,导致制品机械性能逐渐下降,产生变脆、龟裂和发黄现象甚至完全破坏而无法使用。提高材料抗老化性能的方法是在纺丝后道即上油的过程中均匀喷涂含有一定比例抗紫外线吸收剂的油剂。传统的喷油装置上 ...
