What is the elastic recovery of 3075 yarn after long-term use?

The elastic recovery of 3075 yarn after long-term use usually shows good performance, mainly due to its spandex (Spandex) component and the structural characteristics of polyester fiber. Since 3075 yarn contains spandex, spandex has excellent elasticity and resilience properties and can quickly return to its original shape after stretching. This allows the 3075 yarn to maintain good elasticity after being stretched and worn many times, ensuring that the socks can still fit tightly against the feet without loosening after long-term use.

Fatigue resistance: Spandex fiber has excellent fatigue resistance and can withstand repeated stretching and bending without permanent deformation. When 3075 yarn is used in socks, the elastic fiber can still maintain a high elastic recovery rate after daily wear and multiple washings.

Polyester covers spandex fibers to provide additional structural support and abrasion resistance. The toughness and stability of polyester help maintain the overall shape and strength of the yarn, preventing spandex from failing due to wear or fatigue after prolonged use. After proper textile processing, 3075 yarn can maintain long-term elasticity after being made into socks. Even after being put on, taken off and washed many times, the elasticity of the socks can still be maintained well and there will be no obvious sagging or loss of elasticity.

The elastic recovery of 3075 yarn is very good after long-term use. This is mainly due to the high elasticity of spandex fiber and the supportive effect of polyester fiber, which allows the socks to remain tight and comfortable after repeated stretching and wear. Such performance ensures that socks made of 3075 yarn maintain comfortable properties over long periods of use.
