Problems solved by technology

[0007] At present, the existing polyethylene fiber yarn has poor toughness, low wear resistance, and is not resistant to cutting. Moreover, the existing spinning machine has a single function and can only be drawn or rolled up separately, which is time-consuming and laborious, and the production efficiency is low.

Abstract

The invention discloses a polyethylene fiber yarn. The polyethylene fiber yarn comprises the following raw materials of polyethylene fibers, sisal fibers, viscose fibers and basalt fibers. The invention also discloses a production process of the polyethylene fiber yarn. The production process comprises the following steps of firstly, opening and carding fibers to obtain fiber slivers; secondly, drawing the carded fiber slivers to a spinning drawing frame for drawing; then carried put roving and spinning processes on the drawn fibers; and finally unwinding a yarn from a bobbin and winding the yarn on a bobbin to form a bobbin yarn to obtain the polyethylene fiber yarn. The polyethylene fiber yarn has the characteristics of high tenacity, wear resistance and cutting resistance, the spinningdrawing frame can be used for winding the yarn at the same time of doubling, the problem of single function of a traditional spinning machine is solved, and the spinning drawing frame is convenient tooperate, simple in structure, less in energy consumption and good in application prospect in the textile field.

Description

technical field [0001] The invention belongs to the technical field of yarn manufacturing, and in particular relates to a polyethylene fiber yarn and a production process thereof. Background technique [0002] Textile is a traditional advantageous industry. In recent years, people have carried out various developments and researches on new textiles from raw material processing technology, and various yarns and fabrics with good comprehensive performance have emerged. Environmental protection, comfort and appearance have always been the focus of people's pursuit. [0003] In recent years, non-metallic composite fiber materials have been widely used in civil engineering fields such as aviation, aerospace, military equipment, sports equipment, bridges, tunnels, and building reinforcement. At present, there are three types of fibers used in known composite materials: one is carbon fiber sheet, carbon fiber has excellent mechanical properties and high modulus advantages, but its...
