Abstract

The invention discloses an anti-cutting fiber and a preparation method and application thereof. The anti-cutting fiber is curled, the cross sections of the anti-cutting fiber has a multilayered structure, the multilayered structure comprises an outer layer, a first inner layer and a second inner layer, the first inner layer and the second inner layer are arranged in the outer layer, the outer layer is made of polyethylene, the first inner layer and the second inner layer are made of polyethylene of which the molecular weight range is 1,100,000-1,450,000, and fiber fillers, inorganic fillers and strip-shaped metals are uniformly distributed in the second inner layer. A glove which is made from the anti-cutting fiber is woven by double-layered fibers, and conforms to the European (EU) 2016 / 425 anti-cutting standard, the half soles of a worker are protected, furthermore, arms of the worker are protected, and the forearms of the worker are prevented from harm such as high temperature, scorching heat, cutting and the like.

Description

technical field [0001] The invention relates to the technical field of cut-resistant fibers, in particular to a cut-resistant fiber and its preparation method and application. Background technique [0002] According to statistics, hand injury accidents account for 25% of all kinds of industrial accidents. my country has a large industrial population and labor-intensive characteristics. In order to control and reduce the occurrence of hand injury accidents, various types of anti-mechanical injury gloves are constantly being used. Development, including canvas, gauze cloth, cowhide pigskin flannelette and roving, etc. or mixed with canvas and leather. Ultra-high molecular weight polyethylene fiber cut-resistant gloves have developed rapidly due to their comfortable feel, excellent performance, and long service life. They are favored by more and more workers abroad. At present, my country's annual production of ultra-high molecular weight fiber cut-resistant gloves is about 3.5...
