How We Produce Your Sustainable Bulk Shirts
Our eco-manufacturing process follows four strictly controlled phases ensuring quality consistency and minimal environmental impact.
Stage 01
Certified Fiber Sourcing
Raw organic cotton, bamboo, and post-consumer rPET fibers are inspected and verified via GOTS and GRS chain-of-custody tracking.
Stage 02
Low-Impact Dyeing & Cutting
Fabric is processed with non-toxic, low-liquor reactive dyes. Computerized CAD markers minimize fabric cut waste.
Stage 03
Precision Assembly & Trims
Garments are assembled on line-monitored sewing stations equipped with organic thread and recycled trims.
Stage 04
AQL 2.5 Audit & Eco Packing
Final inspection follows AQL 2.5 standards before goods are folded into compostable polybags and barcoded for distribution.
