A self-built quality certification system — every batch of fabric is tested against our published standards before it leaves the factory. No third-party dependency, no hidden specs. What we promise is what we deliver.
MTQS is not a purchased certificate — it is a set of rigorous internal quality standards that every Mujia Textile fabric must pass before shipment. We developed it because we believe quality should be transparent, not locked behind expensive third-party fees. Every MTQS-certified product comes with a unique certificate number traceable to the batch and testing date.
Every certified fabric is tested against the following parameters. Values shown are standard pass thresholds for cotton woven fabrics.
