Introduction

Kevlar Sewing Thread is used in the household sewing machines or high speed industrial sewing machine for sewing filter bag, fire bag, fire blanket, etc, which can be long-term used under 200 ℃.

Performance

Aramid fiber sewing thread is twisted by Para aramid staple fiber yarn, it takes all the advanges of aramid fiber, so it has better porformance than the normal sewing thread.

Para aramid can be used continuously in a very wide temperature range from -196℃ to 204℃.,It has no decomposing or melting at 500℃. Its tenacity remains 75% after 100hours under 200℃.

Due to the high hydrogen bonds, the strength of para aramid can reach up to above 28g/D. Its specific strength is 5-6 times that of steel wire, its specific modulus is 2-3 times that of steel wire or glass fiber, and its flexibility is 2 times that of steel wire while the weight is only 1/5 that of the steel wire. Para aramid is acid and alkali resistant, anti-aging with good adhesive force in rubber.

Advantages:

---Ultra high tensile strength--- 5~6 times of steel wire
---High elastic modulus--- 2~3 times of steel wire or glass fiber
---High temperature resistance and outstanding flame retardance

---Good resistance to abrasion
---Dimensional Stability
---Acid and alkali resistance 

Application:

- Industrial conveyor belt
- Printing and dyeing
- High temperature drying
- Protective gloves, etc

Feature:

1. high strength 
2. insulation and impact resistance 
3. high temperature resistance 
4. low density

5. fireproof
