What are the characteristics of spandex fabric?

The characteristics of spandex fabric are as follows:

1, spandex fabric often uses composite yarn, that is, core-spun yarn elastic fabric with spandex as the core and other fibers as the sheath, which has good adaptability to the body.

2. The appearance style and wearability of spandex elastic fabric are close to those of similar products coated with outer fiber fabric.

3. Spandex has high elasticity, and it is often mixed in the fabric at the ratio of 5% ~ 30%, and all kinds of spandex fabrics obtained have comfortable elasticity of 15% ~ 45%.

Extended data:

Advantages of spandex fabric:

1, high elasticity-its elongation at break can reach 450%~800%.

2. The recovery rate of high recovery-elongation is 90%, and the retraction force during rebound is less than the tensile force.

3. Comfortable to wear-no oppressive feeling of rubber thread.

4. It has good acid resistance, alkali resistance and light resistance.

5. It has high extensibility, good shape retention and no wrinkling.

6, soft and smooth, the best elasticity, comfortable to wear, considerate fit.

7. It has good dyeability and should not fade.

Shortcomings of spandex fabric:

1, poor hygroscopicity.

2, spandex is usually not used alone, but blended with other fabrics.

3. Poor heat resistance.
