I'm interested in sourcing various cotton and polyester yarns for our upcoming production. Specifically, I would like to know more about the availability, pricing, and delivery options for the cotton and polyester blends in both thicker and finer weights. Additionally, please provide details on the minimum order quantities, lead times, and any quality certifications your products may have. It would be great to understand any bulk discount options as well. Looking forward to your prompt response!
