MAKING TEXTILE FABRICS, e.g. FROM FIBRES OR FILAMENTARY MATERIAL (weaving D03; knitting D04B; braiding D04C; net-making D04G; sewing D05B; tufting D05C; finishing non-woven fabrics D06); FABRICS MADE BY SUCH PROCESSES OR APPARATUS, e.g. FELTS, NON-WOVEN FABRICS; COTTON-WOOL; WADDING (non-woven fabrics having an intermediate or external layer of a different kind, e.g. of woven fabric, B32B)
 D04H

Note(s)

  1. In this subclass, the following expression is used with the meaning indicated:
    • "non-woven fabrics" means 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 D. This expression includes felts, cotton-wool and wadding.
  2. In this subclass:
    • some of the non-woven fabrics can also be regarded as "layered products" within the meaning of subclass B32B, and further classification in that subclass should be considered in accordance with the notes thereto;
    • in cases where the making of non-woven fabrics involves the use of particular chemical compounds or compositions, e.g. for treating or bonding fibres, filaments, or yarns, further classification in other appropriate subclasses should also be considered.
  3. By varying the proportions of fibres or threads, and the chemical compounds or compositions, the final products may be given the appearance of paper, cardboard, leather, or the like.

P:0 D04H 1/00
Non-woven fabrics formed wholly or mainly of staple fibres or like relatively short fibres
 D04H 1/40
·  from fleeces or layers composed of fibres without existing or potential cohesive properties
 D04H 1/42
·  ·  characterised by the use of certain kinds of fibres insofar as this use has no preponderant influence on the consolidation of the fleece
 D04H 1/44
·  ·  the fleeces or layers being consolidated by mechanical means, e.g. by rolling
 D04H 1/45
·  ·  ·  by forming intermeshing loops or stitches from some of the fibres (knitting D04B; sewing D05B)  [4]
 D04H 1/46
·  ·  ·  by needling or like operations to cause entanglement of fibres (D04H 1/45 takes precedence; needling machines D04H 18/00)  [4]
 D04H 1/48
·  ·  ·  ·  in combination with at least one other method of consolidation, e.g. with application of bonding agents

·  ·  by welding together the fibres, e.g. by partially melting or dissolving (in combination with needling D04H 1/48)
 D04H 1/56
·  ·  ·  in association with fibre formation, e.g. immediately following extrusion of staple fibres
 D04H 1/58

 D04H 1/64
·  ·  ·  the bonding agent being applied in wet state, e.g. chemical agents in dispersions or solutions
 D04H 1/70
