Characteristics of Meta Aramid and Wool Blended Yarn

Meta Aramid wool blended series is made of wool and aramid fiber as the main components, mixed with flame-retardant viscose conductive fiber and other raw materials, and spun by spinning equipment. This series, whether knitted or woven, has similar tearing high strength flame retardant performance, low shrinkage and other characteristics due to the inherent characteristics of the fiber itself. The Fabric feels soft and has the style of traditional worsted fabrics. Various protective clothing made from this fabric has changed the rigid characteristics of traditional protective clothing in the past. At present, this kind of fabric has gradually replaced imports and has been widely evaluated in the fields of PLA combat training uniforms, public security armed police uniforms, oil exploration, and fire protection in hotels, hospitals, and homes.

Raw material properties
1. 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 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 will not start to carbonize until 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. In the future, as people's awareness of safety protection increases. Aramid fabrics will have a wider application.

3.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. At present, our company uses flame retardant viscose fiber produced by Lenzing. Aramid wool blended yarn.

4. Conductive fiber
aramid wool blended yarn. Currently, conductive fibers include polyester-based, nylon-based and carbon-based conductive fibers. According to customer needs, we can adjust the use of conductive fibers in different proportions.
