D04B KNITTING
Introduced: September 1968
Description
D04B covers the machinery, processes, and techniques for producing knitted fabrics and garments. This includes knitting machines of all types (flat-bed, circular, warp, and hand-operated), as well as the mechanical systems controlling yarn feeding, needle action, and fabric formation. The classification encompasses plain knitting, patterned knitting, and specialized knit structures, along with related finishing operations and control mechanisms for knitting equipment. Adjacent classes D04C and D04D address lace-making and non-woven fabrics respectively, while D04A covers braiding and related processes.
IPC and CPC are identically structured here. All 19 subcodes exist in both systems.
10 shared codes have differing titles between IPC and CPC.
