1, high strength. Staple strength 2.6 ~ 5.7cN/dtex, high-strength fibers 5.6 ~ 8.0cN/dtex. As low moisture absorption, and its wet strength and dry strength of basically the same. Impact strength 4 times higher than the nylon, 20 times higher than that of viscose fibers.

    2, good elasticity. Elasticity close to the wool, when the elongation of 5% to 6%, the almost complete recovery. Wrinkle resistance than other fibers, or fabric does not wrinkle, good dimensional stability. Elastic modulus of 22 ~ 141cN/dtex, than the nylon 2 ~ 3 times higher.

    3, good heat resistance.

    4, water absorption.

    5, good wear resistance. The best wear resistance second only to wear nylon, other natural fibers and synthetic fibers than are good.

    6, light is good. Lightfastness behind acrylic.

    7, resistance to corrosion. Resistant to bleaching agents, oxidants, hydrocarbons, ketones, petroleum products and inorganic acids. Resistance to dilute alkali, not afraid of mold, but the thermal base can be to break down.

    8, dyeing poor.
