When evaluating Cotton Satin (also known as Cotton Sateen), the most critical factor is the Thread Count (TC); for premium B2B applications, a range of 300TC to 600TC is ideal. You must also verify the Yarn Count, typically 40s, 60s, or 80s, where a higher number indicates a finer, smoother yarn. Ensure the weave is a four-over-one sateen structure to achieve that characteristic lustrous sheen and silky drape. Additionally, confirm the fabric weight (GSM) aligns with your end-use, usually ranging from 110 to 150 GSM for bedding and apparel.
