Characteristics of polypropylene high strength filament


Polypropylene high-strength yarn has become a very competitive fiber raw material in the field of industrial silk because of its anti-aging property, small thermal shrinkage, high strength and high tensile strength and impact resistance. Our polypropylene high-strength wire products can be produced according to customer requirements, welcome to inquire!


What factors affect the tension of polypropylene high-strength yarn, these two points can be seen in the spinning process:


1. The influence of tensile ratio

The tensile process of the primary fiber destroys the original structural form of the primary fiber and generates a new order structure. Under the action of tensile stress and thermal effect, the activity of macromolecular chain segments increases, and various structural units gather along the axial orientation of the fiber, rearrange and add new binding points, so that more molecular chains of the fiber are in a particularly good stress bearing state. The regularity of the three-dimensional structure (that is, crystallization) is produced, and the fiber density increases with the increase of the tensile multiple.


The strength of the fiber increases with the increase of the tensile ratio, and the tensile ratio contributes more to the strength of the fiber.


2. Influence of melting index

The melting index of the raw material indicates the molecular weight of the raw material to a certain extent, and the amount of fiber increases under the same process conditions. When the molecular entanglement is large, the strength of the stretched fiber increases with the increase of molecular weight, and when the molecular weight is low, it is easy to produce slip between molecular chains, which is manifested in the decrease of fiber strength. In the process of polypropylene high-strength silk spinning, several raw materials with different melt indices are used.
