Yarn Manufacturing Programme
Elastane-Covered (Gimped) Yarn Manufacturer — Türkiye
Fersan Tekstil is a vertically integrated polyester producer in Çorlu, Türkiye: we texture around 1,800 tonnes of yarn a month, sell part of it as yarn and convert the rest into fabric in our own knitting and dyeing plant.
Gimped yarn is a composite: a pre-tensioned elastane core wrapped in one or two outer filaments. The sheath does two jobs — it shields the bare elastomeric core from abrasion, heat and chemicals, and it governs how far the yarn can extend. Choosing a gimped yarn is therefore not simply choosing an elastane percentage; the fineness of the sheath, the core denier and the covering construction together decide how the fabric stretches and recovers.
Five constructions are in production: 50/72 and 75/72 sheaths over 20, 30 and 40 denier elastane cores. Total denier is the sheath plus the drafted core, which is why total denier steps up as the core grows within the same sheath. As the elastane share rises, stretch and recovery rise with it, while tenacity falls below that of plain DTY and boiling-water shrinkage widens — the heat-setting window has to be narrowed accordingly.
We supply brands and garment makers across Western Europe, Russia and the CIS, and routinely produce to the test standards of European sports and apparel brands. The ordering terms below are the same figures we quote.
Gimped constructions in production
50D/72f + 30D

The construction is set around your product
Sheath fineness, core denier and intermingle level are chosen together against your machine type and knitting speed; the wrong level causes filament separation and streaks in the fabric. Sampling starts with a short technical conversation, and quotation requests are answered within 2 business days. Batch tenacity, elongation and shrinkage figures are shared in the order report.

Frequently asked questions
What is the minimum order for gimped yarn?
Between 500 and 1,000 kg per colour; the exact figure depends on the construction and is confirmed with the quotation. Trial quantities for development projects are discussed separately.
Which core deniers do you produce?
Production covers 20, 30 and 40 denier elastane cores, with 50/72 and 75/72 textured polyester used as the sheath. Core deniers outside that range are assessed on request.
Single covered or double covered?
The covering construction is chosen for the end use. Single covering can leave residual torque and let the core grin through under extension; double covering gives full coverage and balanced torque. Which is right depends on the fabric structure and the direction of stretch.
Why is gimped yarn less tenacious than plain DTY?
The total denier of a composite yarn is the sheath plus the drafted core, but the load is carried mainly by the sheath. Tenacity expressed in cN/dtex therefore reads lower than for plain textured yarn; that is a consequence of the composite structure, not a quality indicator.
What should we watch in heat-setting?
Boiling-water shrinkage in gimped yarns spreads over a wider band than in plain DTY and rises with the core share. Stenter temperature and dwell have to be set per batch; because we spin the yarn ourselves, yarn shrinkage and knitting tension can be controlled together rather than separately.
What certification applies?
Production runs in a plant certified to OEKO-TEX STANDARD 100 and STeP; where recycled content is required, GRS 4.0 / RCS 2.0 chain of custody applies. The documents are downloadable from our certificates page.
