According to the regulations of the national textile industry, woolen sweaters with a wool content of 100%, whether worsted or roving, are called “pure sweatersâ€. However, in order to improve the spinning performance and improve the durability, the worsted product is allowed to contain not more than 5% of non-wool fibers (such as nylon, polyester, etc.). The woollen finished product is allowed to contain no more than 7% of non-wool fibers.
If used for decoration and the decorative fibers must be visible, the finished non-wool fiber content of the finished product can be relaxed to 7%. The woollen finished product is allowed to contain no more than 7% of non-wool fibers, but the total amount of both (for decoration and improved spinning performance) shall not exceed 7%.
If the pure woolen sweater is added to the non-wool fiber allowed in the standard, the worsted or woollen product can only be labeled as “pure woolâ€, but not “100% woolâ€. 100% of the finished product can be marked with “100% wool†on the sewn trademark or tag.
