Problems solved by technology

[0003] At present, there are many kinds of high-strength and wear-resistant polyester fiber products on the market, most of which are improved by adding toughening agent performance modifiers to their production formulas, and when the functional additives are mixed, they are complicated. The chemical changes of chemical additives, and the improvement of physical properties by chemical additives is usually predictable and easy to know the upper limit of the improvement. The composition of the polyester fiber is used to improve its performance, so that the polyester fiber can expand its application fields, such as adding graphene, etc.

Abstract

The invention discloses a high-wear-resistant composite fiber material and its application. After the composite fiber material is mixed with polyester chips and alloy powder, the polyester chips in the mixing system are heated into a molten state, and are extruded by a twin-screw extruder. After further mixing, it is sent to the spinning device to make a composite fiber material. The chemical composition of the alloy powder is Pt x Al y Fe m P n , wherein, 26≤x≤34, 26≤y≤31, 33≤m≤37, 26≤n≤28; this scheme is not only simple in steps, but also convenient in processing raw materials, and can be applied to industrial production and application.

Description

technical field [0001] The invention relates to the field of fiber materials, in particular to a high wear-resistant composite fiber material and its application. Background technique [0002] Polyester fiber is an important variety of synthetic fibers, which is esterified or transesterified with purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (EG) as raw materials. The fiber-forming high polymer prepared by polycondensation reaction - polyethylene terephthalate (PET), and then the fiber made by spinning and post-processing. [0003] At present, there are many kinds of high-strength and wear-resistant polyester fiber products on the market, most of which are improved by adding toughening agent performance modifiers to their production formulas, and when the functional additives are mixed, they are complicated. The chemical changes of chemical additives, and the improvement of physical properties by chemical additives is usually predictab...
