Abstract

The high modulus and high strength polyethylene fiber extracting and drafting production line includes one godet frame, one first drafting machine, one water washing machine, one second drafting machine, one extracting machine, one hot blast drying box, one third drafting machine, one drafting and heating box, one fourth drafting machine and one winding machine connected successively. The drafting machines are hot roller ones, the drafting and heating box is one double air duct one, and the extracting machine is one multistage or multilayer one. The present invention has reasonable first, short production period, high extracting efficiency, high drafting power, low production cost, high operation efficiency and high product quality.

Description

technical field [0001] The invention relates to a polymer material preparation device, in particular to a high-modulus high-strength polyethylene fiber extraction and drawing production line. Background technique [0002] High-modulus high-strength polyethylene fiber has high strength, high modulus, and high degree of orientation, and is widely used in manufacturing industries such as protective equipment, ropes, fishing nets, and sports equipment. Its production process is usually: dissolving ultra-high molecular weight polyethylene in the first solvent to prepare a polyethylene solution, which is extruded from an extruder, sprayed out from the spinning box, cooled and solidified into a gel fiber, The first solvent is extracted with a volatile second solvent, and then dried and super-drawn to finally obtain the finished fiber. However, the existing extraction and drawing device has unreasonable structure, long process route, unsatisfactory extraction effect, low draft rati...
