Abstract

The invention discloses an aramid fiber and ultra-high molecular weight polyethylene blended yarn and a production method thereof. The aramid fiber and ultra-high molecular weight polyethylene blended yarn comprises the following components in percentage by weight: 20-85% of aramid fiber, 5-15% of ultra-high molecular weight polyethylene fiber, 0-70% of fire resistant fiber and 1-5% of conductive fiber. The production method comprises the following steps of blending conductive fibers with a certain proportion, and pretreating raw materials before spinning, adding an antistatic agent, and standing for at least 8 hours to preform curing treatment. Technological conditions of each process are strictly controlled in a processing process, and temperature and relative humidity of cotton carding, drawing, roving and spinning processes are controlled, so the problem of serious static of the aramid fiber and the ultra-high molecular weight polyethylene during spinning can be solved well, strong rigidity of the aramid fiber is overcome, and the quality of the yarn is ensured.

Description

technical field [0001] The invention relates to a blended yarn and a production method thereof. Background technique [0002] At present, aramid and aramid blended yarns on the market are usually made of 100% aramid, or blended with other materials such as aramid and flame-retardant viscose. The fabric produced by using this yarn has strong High, excellent flame retardant performance, but also has the following disadvantages: 1. The anti-pilling performance of the fabric is relatively poor, and the clothing is prone to hair balls during use, and the hair balls are not easy to remove; 2. The wear resistance of the fabric is not excellent enough . Contents of the invention [0003] The object of the present invention is to provide a kind of blended yarn of aramid fiber and ultra-high molecular weight polyethylene and its production method, so as to overcome the above-mentioned defects existing in the prior art. [0004] The blended yarn of aramid fiber and ultra-high molec...
