The purpose of blending is to reduce the cost of wool fabrics without compromising their original style due to the addition of viscose fiber. However, the addition of viscose fiber can significantly reduce several properties of the fabric, including strength, abrasion resistance, and bulkiness. Therefore, the viscose content in worsted wool fabrics should not exceed 30%, while the viscose fiber content in woolen fabrics should not exceed 50%.

Soak the fabric in cold water for 15 minutes first, then wash it with a general synthetic detergent. The temperature of the washing solution should not exceed 45°C. Heavily soiled areas such as collars and cuffs can be gently brushed with a soft brush. After rinsing thoroughly, gently squeeze out excess water and dry in a cool, well-ventilated place. Do not expose it to strong sunlight or tumble dry, in order to avoid heat-induced wrinkling.
