Factors affecting yarn strength

Factors affecting yarn strength:

Introduction:

It is necessary to test the strength of the yarn to know how strong the yarn is. Yarn strength refers to the amount of tension it can or does resist. The harder the fiber, the harder the yarn will be. However, the strength of the fiber is not the only factor in determining the strength of the yarn. The strength of the fabric depends on the strength of the yarn. In addition, if the yarn is not strong enough during weaving or knitting, it will not be possible to make cloth. For this, it is necessary to test the strength of the yarn to make standard yarn for making different fabrics. In addition to this, the importance of testing the strength of yarn for research and development of new products, testing of consumer complaints, and taking effective steps for special purpose use is immense.

Tensile properties:

To determine the value of yarn in practical work, the strength of the yarn, i.e. the strength of the yarn and its breaking extension when it is twisted, is determined. Also considered are elastic modulus, abrasion resistance, etc. which affect the yarn strength. So there is a system to determine all these qualities of yarn together, which together can be called the tensile qualities of yarn. https://bdfabric.com/how-to-measure-the-twist-of-the-yarn/

Factors affecting yarn strength:

The following factors affect the strength of the yarn.

1. Fiber staple length:

The strength of the yarn depends on the length of the fiber. The strength of yarn produced by long fibers will be higher than that of short fiber yarns. https://bdfabric.com/role-of-yarn-on-fabrics-properties/

2. Fiber fineness:

The strength of fine fiber yarn will be higher than that of coarse fiber yarn.

3. Fiber strength:

The strength of the yarn depends largely on the strength of the fiber. So the strength of all the fibers that make up the yarn must affect the strength of the yarn.

4. Yarn twist:

The fibers are twisted to hold the yarn, which increases the strength of the yarn. However, the amount of spinning increases the strength of the yarn up to a certain limit and if more or less spinning is done, the strength of the yarn decreases.

5. Evenness:

Evenness of anything including yarn count, twist, etc. affects the strength of the yarn. The greater the evenness of the yarn, the greater the strength of the yarn.

6. Fiber length distribution:

The smaller the length of the fiber in a yarn, the greater the strength of the yarn.

7. Fiber finishing process:

The strength of the yarn depends on the amount and type of different chemicals used in the synthetic fiber.

8. Other factors:

The type of equipment used to test the strength of the yarn, the length of the yarn, the efficiency of the tester, the amount of water vapor in the yarn, the weather, etc. affect the strength of the yarn.
