Production process
Six steps. One traceable supply chain.
From auxiliaries and dyeing to final inspection, every stage is owned or tightly partnered — so the fabric you receive matches the sample you approved.
01
Yarn Selection & Warping
Filament and staple yarns — including N66 reinforcement and GRS-certified recycled polyester — are graded and warped for consistent tension.
02
Weaving & Knitting
High-density looms and circular knitting machines produce base cloth to the target weight, weave pattern and stretch profile.
03
Dyeing & Chemistry
In-house dyeing lines developed over 10 years, tuned for colorfastness, brightness and reproducibility batch after batch.
04
Coating & Finishing
Calendaring, DWR treatments, PU/TPU coatings and laminations deliver waterproof, downproof and technical finishes.
05
Quality Control
Pretreatment through final inspection — every roll passes full-batch testing for color fastness, durability and technical standards.
06
Warehousing & Export
Traceable inventory in Shanghai and Suzhou hubs, ready for global export logistics.
Third-party proof
