Para aramid sewing thread

What is para-aramid fiber and what is the synthesis method of para-aramid fiber

1. What is para-aramid?

2. What is the synthesis method of para-aramid fiber?

3.Para  Aramid Spun Yarn is made from 100% para aramid staple fiber and produced on ring spinning systems or Votex systerm 

Para aramid  sewing thread property 

• Inherently Flame Retardant, High Temperature Resistance, High Strength, High Modulus, Tensile Strength
• Bulletproof, explosion-proof, electrical insulation, arc-proof, high dimensional stability, extremely low creep, small size, light weight
• Corrosion resistance, acid and alkali resistance, organic solvents resistance 
• Heat and fire resistance, excellent cut resistance
• Negative coefficient of thermal expansion, soft and comfortable hand feel 
• Excellent thermal stability, low heat conductivity, no melting no dripping
• Low flammability the limiting oxygen index(LOI) is 29%, start to carbonise and decompose above 500°C
• Excellent high temperature resistance, It is able to work for a long period of time under acid base from -200°C to 250°C
• 70% strength of threads remains after being in 290°C for 1000 hours
• Para aramid  is sensitive to prolonged exposure to ultraviolet (UV) rays although it does not imply a deterioration of it

 What are the applications of para-aramid sewing thread?

1. Stitching for Safety shoes, Protective gloves, Aircraft seats, Airbags.
2. Use for Embroidery thread, cross handstitch.
3. Para aramid sewing thread is used for weaving woven fabrics and knitted fabrics, and the woven fabrics are mainly used for protective clothing in flame-retardant and high-temperature-resistant industrial fields, such as metallurgy, steel mills, aluminum plants, chemical plants, power plants, etc.  In addition, it can be used as high-speed embroidery thread, sewing thread for industrial products and protective clothing.
4. Gloves made from para-aramid spun yarn can prevent fingers from being cut, rubbed, punctured, high temperature and flames during industrial operations.
5. Para aramid spun yarn  is used in various webbings, and has been widely used in industrial conveyor belts, safety protection belts, industrial hoisting belts, glass tempering furnace roller belts and many other fields that have special requirements for webbing.
6. The straps on the edge of the mattress are used for edging.
7. Main use for Petro chemical industry,Oil and Gas Industries, FR Workwear , Utility and Subcontractor Wear,  Emergency Wear, Firefighter Uniforms, lndustrial Workwear.
