Fiber and yarn
Material identity, yarn geometry and traceability determine fabric behaviour before knitting begins.
01
Fiber Selection and Product Target
Cotton, polyester, viscose, modal, lyocell or polyamide must be chosen against end use, care cycle, hand feel, cost and claim requirements.
02Cotton Fiber Quality and Bale Management
Staple length, fineness, strength, maturity and contamination influence yarn evenness and dyed appearance.
03Certified Fiber and Traceability
Organic or recycled-content claims require valid scope documentation and chain-of-custody evidence, not merely a material name.
