Description
D04H encompasses processes and apparatus for manufacturing textile fabrics directly from fibres or filamentary materials without traditional weaving or knitting methods. This classification covers non-woven fabric production technologies, felting processes, and related materials such as cotton-wool and wadding used in textiles, filtration, insulation, and absorbent applications. The subclass includes both the manufacturing machinery and the resulting fabric products, addressing techniques such as mechanical interlocking, thermal bonding, and chemical binding of fibre webs. Related braiding, lace-making, and knitting technologies are classified separately in D04B–D04G.

Glossary
Non-woven fabrics non-woven fabric Fabrics formed wholly or partly of textile material by processes comprising operations other than the weaving, knitting, braiding, lacing, or knotting of yarns, threads, or filaments for which provision is made in other subclasses of section . This expression includes felts, cotton-wool and wadding. Composite fibres Conjugated fibres that are manufactured by composite spinning of two or more kinds of immiscible resins, of which the resins form such phase structures as side-by-side, sheath-core, sea-island, wood grain pattern, multi-layered, radial or mosaic in the cross section surface vertical to the fibre axis. Mixed fibres Mixture of two or more kinds of fibres made of different substances. Fleece fleeces Fabric composed of a foundation layer with a thick, soft nap or pile, in which any type of fabric, including a knit or a woven fabric, can be incorporated as a foundation layer. A fleece should be treated as a single layer, not as a layered product. Pile Upright loop or nap raised from the surface of fabrics.
Limiting references
