D03D

WOVEN FABRICS; METHODS OF WEAVING; LOOMS

Introduced: September 1968

Description

D03D covers woven fabrics produced through interlacing of warp and weft yarns, including the methods, processes, and mechanical equipment (looms) used in textile weaving. This subclass encompasses fabric construction techniques, loom design and operation, weaving machinery, and the resulting fabric structures and properties. It addresses both traditional and modern weaving technologies, from hand looms to industrial automated systems, and includes innovations in weft insertion mechanisms, warp control, and fabric formation methods.

IPC and CPC are identically structured here. All 26 subcodes exist in both systems.

6 shared codes have differing titles between IPC and CPC.
