Modal fiber is a type of cellulose fiber. Like rayon, it belongs to the cellulose fiber category and is a genuine man-made fiber. It is produced from wood pulp made from European shrub forests and then processed using a specialized spinning technique. Modal products are known for their excellent softness and moisture absorption, although fabrics made from Modal have relatively poor stiffness and shape retention and are now widely used in production.
Polyester-viscose blending is a highly complementary type of blended yarn. It includes cotton-type, wool-type, and medium-length fiber varieties. Wool-type fabrics are commonly known as “Kuai Ba.” When the polyester content is no less than 50%, the blended fabric can retain the advantages of polyester, including high strength, dimensional stability, and good wash-and-wear performance. The addition of viscose fiber improves the breathability of the fabric, enhances its resistance to melting holes, and reduces pilling and static electricity. A commonly used polyester/viscose blend ratio is 65/35. Such blended fabrics are characterized by a smooth and clean surface, bright colors, a strong wool-like appearance, good elasticity and hand feel, and good moisture absorption.
