What Isoteks does

İsoteks Tekstil İthalat İhracat A.Ş. (Isoteks) is a privately held Turkish joint-stock company founded in 1993 in Bursa, self-described as Turkey's largest textile trading company. It operates as a B2B import-export platform for textile raw materials, sourcing fibers, yarns, and fabrics from producers in 13 countries and distributing them to textile manufacturers across Turkey, the Middle East, and Europe. The company runs an enterprise field-sales motion supported by a dedicated customer contact center and multilingual (9-language) corporate web presence.

Its core product portfolio spans three categories: Elyaf/Fiber (polyester fiber, viscose fiber, POY, and chips), İplik/Yarn (polyester textured yarn/flat yarn/DTY/FDY, spun and blended yarns, dope-dyed variants, and approximately 20 specialty yarn types including flame-resistant, cationic, micro fiber, and peach-skin), and Kumaş/Fabric (chiffons, crepes, satins, dobby, and spandex-blend greige fabrics). Over 70% of products are developed through proprietary in-house R&D and UR-GE, with approximately 72 yarn varieties in inventory, of which around 40 are Inditex-certified. Operations are anchored at a 10,300 m² LEED Gold-certified green factory in Bursa Demirtaş and a 1,200 m² international warehouse at the Bursa/Gemlik Free Zone.

The business model is B2B commodity and specialty trading: revenue is generated through markups on import and export of textile raw materials across 13 sourcing countries, with quote-based B2B pricing (not publicly disclosed). The company is organized as a group of wholly-owned subsidiaries including İsoteks İplik (FDY/DTY yarn trading), İso Enstitü (textile training and consulting), İsoteks Free Zone, İso Technotex (flame-resistant home textiles), and Isoteks Hong Kong (Asian sourcing). Differentiators include trend-setting in-house yarn development, free technical support (sample fabrics and conversion recipes), and sustainability offerings under Recycleyarns.com.
