D06C FINISHING, DRESSING, TENTERING OR STRETCHING TEXTILE FABRICS
Description
D06C encompasses machinery and processes for post-weaving or post-knitting treatment of textile fabrics, including finishing operations that impart desired properties such as smoothness, stiffness, or aesthetic appearance. It covers tentering frames and stretching devices used to set fabric dimensions and remove wrinkles, as well as dressing processes that apply sizing agents or other chemical treatments. This subclass excludes general laundering and cleaning operations (D06B) and specific dyeing or color application methods (D06B or D06P), focusing instead on mechanical and chemical finishing treatments that prepare fabrics for final use.
Filing statistics
CPC subclass D06C recorded 16,949 patent applications worldwide between 2013 and 2023. Annual filings grew from 629 in 2013 to 1,525 in 2023 (+142%), peaking at 2,476 applications in 2020. The most active applicants in class D06 are LG ELECTRONICS (7,955 applications), QINGDAO HAIER WASHING MACHINE COMPANY (7,190 applications) and HAIER SMART HOME (5,471 applications).
