Frequently Asked Questions (B2B Industry Insights)

What are the advantages of 80S Lenzing Modal in thermal underwear?
80S Modal offers a significantly higher thread count, resulting in a silkier feel, better moisture absorption, and superior thermal retention compared to standard cotton or low-grade polyester blends. It is also naturally biodegradable.
Can you handle OEM/ODM orders with custom size charts?
Yes, we specialize in customizing size charts for European, North American, and Asian markets, including "Plus Size" ranges. Our technical team can adapt designs based on specific regional anthropometric data.
What is the "Fake Translucent" technology in fleece leggings?
This is a specialized layering technique where a flesh-colored fleece lining is bonded with a sheer outer stockings layer, providing the aesthetic look of thin pantyhose while offering the warmth of 200g-300g fleece.
How do you ensure quality control for large wholesale exports?
We implement a multi-stage QC process: initial fabric testing, in-line inspection during sewing, and a final 100% manual inspection before packaging to ensure zero defects in seams, elasticity, and color consistency.
What are the typical lead times for bulk orders?
For standard designs, lead times are typically 15-30 days. For custom OEM orders involving specific fabric dyeing, lead times range from 45-60 days depending on the volume and technical complexity.
