This nylon thread is manufactured with premium nylon material and professional twisting technology. It maintains stable toughness under long-term tension, and the smooth surface ensures easy threading without frequent breakage during operation. It can withstand complex outdoor environments, resisting corrosion and temperature changes to extend service life.
It is widely accepted for both industrial and household uses. For industrial production, it works well in heavy-duty sewing jobs for leather, canvas and woven goods. For daily use, it fits fishing, bundling and general repairing tasks. The 500g cone packaging provides sufficient length for continuous work, helping users improve working efficiency and control procurement cost.
Our twisted nylon sewing thread is manufactured using high-grade virgin nylon 6.6, ensuring exceptional resistance to abrasion, chemicals, and UV degradation. The 0.4mm diameter provides a perfect balance of strength and hand feel, while the 500g spool offers ample length for large-scale production without frequent changeovers. Each spool is wound with precision to minimize tangles and ensure smooth feeding through high-speed sewing machines.

Frequently Asked Questions
Q1: What is the recommended needle size for this thread?
A: For 0.4mm diameter nylon thread, we recommend using needle sizes between 90/14 and 110/18, depending on fabric thickness. Always test on a scrap piece first.
Q2: Can I use this thread for outdoor applications?
A: Yes, nylon has good UV resistance, but prolonged direct sunlight exposure may cause gradual degradation. For outdoor use, we suggest applying a protective coating or using our UV-stabilized variant (available on request).
Q3: Is the thread pre-treated for lubrication?
A: Yes, our thread is lightly lubricated with a silicone-free finish to reduce friction during sewing. This minimizes needle heat and thread breakage.
Q4: Can I order a sample before bulk purchase?
A: Absolutely. We provide free samples (up to 100g) for qualified customers. Contact our sales team to arrange a sample request.
Q5: What is the typical lead time for large orders?
A: For standard colors and packaging, lead time is 10-15 working days after order confirmation. Custom colors may require an additional 5-7 days.
Q6: Is this thread suitable for sewing leather?
A: Yes, its high tensile strength and abrasion resistance make it ideal for heavy leather, but we recommend using a leather needle and adjusting tension accordingly.
Q7: How should I store the thread?
A: Store in a cool, dry place away from direct sunlight. Keep the spool in its original packaging or a sealed container to prevent dust accumulation.
Q8: Do you offer custom colors with low minimum order quantities?
A: Yes, we can produce custom colors with a minimum order of 500 kg per color. For smaller quantities, we may have stock colors available. Please inquire.
