Elastic Yarn for Hosiery Stretch & Recovery Performance
- Controlled Stretch
The elastic core provides controlled extension under tensile load, allowing the yarn to accommodate the dimensional changes required during hosiery knitting and wear.
- Elastic Recovery
After stretching, the yarn is designed to recover toward its original length. Recovery behavior depends on the Spandex/Elastane specification, covering construction and applied extension.
- Repeated Extension Behavior
The yarn undergoes repeated stretching during knitting and use. Its elastic response is influenced by core denier, yarn construction and the degree of extension applied.
- Fabric Shape Retention
When incorporated into hosiery, the elastic yarn contributes to the fabric's ability to extend and return toward its initial dimensions, supporting consistent fit around areas such as cuffs, ankles and leg sections.
Elastic Yarn Quality Control
Denier & Specification Verification
Finished yarn is checked against the specified denier and construction to identify variation in the delivered yarn.
01
Tensile & Elongation Testing
Tensile strength and elongation are evaluated to verify the yarn's mechanical behavior against the agreed technical specification.
02
Elastic Recovery Assessment
Stretch-and-recovery performance is tested under defined conditions to assess how the yarn responds after extension.
03
Covering & Surface Inspection
The yarn is inspected for covering condition, surface appearance and visible structural variation to identify irregularities that may affect subsequent hosiery processing.

FAQ
What types of hosiery can use elastic yarn?
It can be used in socks, stockings, seamless hosiery, elastic cuffs and other knitted products where controlled stretch is required.
How do I choose the appropriate yarn for a hosiery project?
Selection depends on the fabric construction, knitting machine, required stretch level, finished-product dimensions and the position of the yarn within the hosiery.
Can it be used for different sections of a sock?
Yes. Different yarn specifications may be selected for areas such as cuffs, leg sections and other zones according to the required fabric construction and elasticity.
