Application of nano barium sulfate in manufacturing chemical fibers and chemical fiber

Abstract

The invention discloses a novel application of nano barium sulfate, which not only broadens the application scope of the nano barium sulfate but also improves mechanical properties of polyethylene fibers. The process of manufacturing chemical fibers by the nano barium sulfate is simple, has reasonable and reliable technical indexes, is easy to operate and greatly improves the mechanical properties of the polyethylene material, such as tensile strength, impact strength, elongation at break and the like. The use of the nano barium sulfate can greatly reduce the production cost of the polyethylene fibers and further broaden the popularization and application scope of the polyethylene fibers.

Description

technical field

[0001] The invention relates to the use of nanometer barium sulfate in manufacturing chemical fibers and the chemical fibers. Background technique

[0002] Polyethylene chemical fibers are widely used in various industries, especially in fishing nets, ropes and other industries. However, there is a certain gap between the mechanical properties of polyethylene itself and nylon, which cannot meet some high-strength applications, resulting in limitations in its application and promotion.

[0003] The various aspects performances of polyethylene fiber and nylon produced in the prior art are as follows:

[0004] Variety Tensile strength MPa Elongation at break% Notched impact strength kJ / m 2 Tensile Grade Polyethylene 24 500 15 Brushed Grade Nylon 60 200 10

[0005] But although the polyethylene fiber in the prior art has possessed corresponding mechanical strength to a certain exte...
