The widely used and superior performance of polypropylene stretch yarns are due to the characteristics of polypropylene fiber. The following is a brief introduction to the characteristics of polypropylene fiber.

Polypropylene stretch yarn / polypropylene yarn / polypropylene low elastic yarn is widely used in weaving, jiaozi, ribbon, headdress, sweater, wrist, kicking, gloves and other needs of a specific flexibility of the product.

Polypropylene fiber inherent properties:
(1) specific gravity of 0.91, the proportion of the existing fiber material is the lightest.
(2) strength higher than the average natural fiber, generally 3.96 ~ 6.16cN / dtex.
(3) acid and alkali resistance, good chemical stability.
(4) has a unique wicking effect.
(5) moisture regain of 0.03%, basically no moisture.
(6) warm and strong, relative thermal conductivity of 6.0, close to the wool 6.4.
(7) with mildew, moth, low cleanliness of the excellent performance
