Meta Aramid Wool Spun Yarn

1.Wool. Wool is a natural protein fiber with complex physical and chemical properties. It has a soft feel, a strong texture, good elasticity and warmth retention, and a natural and soft luster. The limiting oxygen index of wool is about 25%, the lightning is 570-600℃, and the maximum combustion temperature is 180℃. It is a natural flame-retardant fiber. It will not melt or drip when it burns, and the foam produced is very thick and has good insulation. The moisture regain of wool is high. The relative humidity is 60%, the nitrogen content is 15-16%, and the sulfur content is 3-4%. The higher nitrogen content makes it have higher flame retardancy.

2.Aramid. Aramid includes meta aramid and para aramid. It has good heat resistance and combustion resistance. The limiting oxygen index is 28%, it can withstand a temperature of 300 degrees, and it starts to carbonize when it exceeds 400 degrees. It has high strength. It has good thermal insulation performance and is currently widely used in firefighting suits and high-end tooling fields.

3.Flame retardant acrylic yarn is a special type of synthetic fiber that is made by adding specific flame retardants during the production process. These flame retardants combine with the molecular structure of the fibers to give them flame retardant properties. The main features of flame retardant acrylic yarn include: Flame retardant performance: When encountering an ignition source, its combustion speed is slower and less toxic smoke is released, thus improving the safety of the fire site. Flame retardant acrylic is production of fireproof clothing, flame retardant carpets excellent materials.

4.Flame retardant viscose, flame retardant viscose fiber made by adding flame retardant. Oxygen index is greater than 30, with good spinnability. It can withstand multiple washings and is a permanent flame retardant fiber with good hygroscopicity and a cotton-like feel. 

5.Conductive fiber, aramid wool blended yarn. Currently, conductive fibers including stainless steel metal fiber and carbon-based conductive fibers. According to customer needs, we can adjust the use of conductive fibers in different proportions. Such as metal fiber and carbon filaments.
