Introduction

PTFE sewing thread is made of 100% polytetrafluoroethylene resin material with high-quality temperature resistance(-196~260℃), corrosion resistance, hydrolysis, oxidation resistance, and other properties.

 Features:

1. The single strand of this product is manufactured by the extruding process, with circular diameter, uniform and full trace, small shrinkage, stable elongation, and large continuous length(the maximum weight specification of 1350dtex conventional line is 1000g/spool and continuous length is 7500m), which is suitable for high-speed sewing machines. In addition, in order to enhance the fastness of stitching, 1650dtex(1500D), 2000dtex(1800D), 2650dtex(2400D) for bag top, bag bottom and other special specifications are equipped.

2. In order to ensure the fastness of sewing, this product is made of “long filament” without any bonding and stitching methods. the length of the sewing thread is artificially increased to ensure the safety of the sewing thread and the safety of the filter bag.

3. Because PTFE material has a very strong self-lubrication property and extremely low friction coefficient, if there is a stitch jumping during sewing, an appropriate amount of silicone oil can be coated on the sewing line to prevent this situation from happening.

4. Due to the particularity of the manufacturing process, there is a 10% error range in linear density and strength parameters.

Application:

Our products are widely used in environmental protection, filtration, chemical industry, sunshade sail, and other fields.
