Properties of Modacrylic

• Strength: The fiber is of moderate strength and is twice as strong as wool. It is weaker than cotton, linen and silk. The fiber has a fairly good abrasion resistance.



• Elasticity: The elasticity of modacrylic can be compared to that of acrylic. It has little stretchability and there tends to be a moderate amount of recovery when stretched. The fiber has good dimensional stability and shape retention.



• Resilience: The fiber has excellent resilience. It does not wrinkle fast and they tend to fall out easily.



• Absorbency: The fiber is less absorbent than both the natural and various man made fibers.



• Heat Conductivity: The fiber is not a good conductor of heat, which is due to its chemical composition.
