Import Bonded Nylon Greige Yarn 420d/3 Dyetube — Buy in wholesale FOB from Supplier in China

Bonded Nylon Greige Yarn 420d/3 Dyetube is a high-tenacity nylon 6.6 yarn designed for industrial sewing applications, supplied in greige state for downstream dyeing. The yarn is composed of three filaments bonded with a resin coating to resist friction and heat generated during high-speed needle penetration. It is wound on dyeing tubes sized H230/Dia.56 or H170/Dia.56, with standard weights of 1kg, 1.5kg, or 1.8kg per cone and no knots in the winding. This construction ensures consistent feeding through automated sewing and embroidery machines.

The base material is polyamide 6.6, known for its strength and thermal stability under continuous operation. The resin bonding is applied as a thin, uniform layer that does not alter the yarn's diameter significantly but improves abrasion resistance and reduces lint generation. Typical industry standards for bonded nylon sewing yarns include a tenacity range of 6.5 to 8.0 g/denier and elongation at break between 20% and 30%. Lubricated variants are available for machines requiring reduced friction, though this is not standard unless specified.

This yarn is primarily used by manufacturers of heavy-duty apparel, automotive upholstery, outdoor gear, and industrial textiles requiring durable seams. Buyers include contract sewers, mattress producers, and bag makers sourcing thread for high-stress stitching. The product is supplied in bulk on dyeing tubes, ready for vat or continuous dyeing. Trade terms typically include FOB Tianjin or CIF destination, with minimum order quantities negotiated per batch. Packaging is standard carton, with each carton holding multiple cones depending on weight.

Tianjin Bonlon Textiles Co., Ltd operates as a manufacturer of industrial sewing threads from Tianjin, China. The company is registered with a physical address in Tianjin and is classified as a harbor-tier supplier, indicating verified production capacity and export experience. There is no public data on company age, workforce size, or annual turnover. The listing shows no response rate or average response time, suggesting limited buyer communication infrastructure.

The supplier focuses exclusively on bonded nylon and polyester sewing threads, with product lines including greige yarns for dyeing and finished threads for direct use. It does not claim certifications such as ISO, OEKO-TEX, or GOTS, nor does it list any branded clients or export destinations. The absence of response metrics and certification claims implies buyers must verify capabilities directly before placing orders.
