What factors affect the strength of rayon yarn?

Rayon thread is a kind of artificially imitated thread, which is very different from cotton thread and has very different characteristics. In terms of strength, rayon yarn is very strong, but different rayon yarns have different strengths, mainly because the strength of rayon yarn is affected by several factors. A brief introduction in the Viscose Yarn Editor.

The main factors affecting the strength of Polyester Filament Yarn are:

1. Fiber properties

Including fiber length and density, in general, the longer and thinner the fiber, the greater the frictional resistance between the fibers, the less slippage occurs, and the higher the natural strength. improve its strength. Of course, if the fiber strength is high, the rayon yarn will also be strong, and if the fibers are relatively uniform, the strength will be high.

2. Twist

As the twist increases, the frictional resistance between the fibers also increases, making it more difficult to pull out. This is an advantage of short fiber yarn.

3. Joint stock

Single yarns can make the strands uniform, but the resultant force between the outer fibers is increased by contact, and its strength is much higher than the sum of the single yarn strengths.

The above points are important factors that affect the strength of rayon yarn, and they are important factors related to the effect of using rayon yarn.
