CPC Definition - Subclass D06N
This place covers:
Fibrous webs coated with at least one layer of a macromolecular material to impart specific properties and/or to be used in a particular application, such as wall or floor coverings, e.g. linoleum, PVC floor coverings, carpets or artificial turf, artificial leather, building materials including roofing membranes or underlays, wearing apparel, airbags, footwear, gloves, upholstery, tents, canopy, tarpaulins.
Wallpaper comprising a textile layer.
Methods or apparatus for making these products.
The subclass has a very large number of related technical areas, e.g.:
"Material fields per se" such as polymer materials or compositions and kind of fibrous web.
Fields covering (per se) manufacturing methods/apparatus e.g. B05D, B29C, B32B 37/00-B32B 43/00, D06M 23/00, D06B or D06C.
"Application fields" such as wall, floor or roof coverings, airbags, building materials, artificial turf, wearing apparel, footwear or gloves.
"Overlapping fields" like polymeric treatment of fibrous webs ( D06M 15/00), carpet underlays (A47G 27/0468) or multilayer products in case of extrusion coating (B32B).
If the coated fibrous webs are specially adapted for particular applications having own subclasses or if a very specific fibrous web or polymer are used classification is also made in the pertinent subclasses listed in section "Informative references".

The "common rule" applies in each of the subgroups.
In case of combination of chemical and mechanical aspects, several classification symbols covering all these aspects are given.
Within each of the subgroups D06N 3/0056 and D06N 3/02 - D06N 3/16, the polymer composition comprising different polymer(s) and additive(s) is classified at least according to each of the essential components.
Coatings with mixtures of polymers covered by two or more of subgroups D06N 3/02 - D06N 3/16 are classified in each appropriate subgroup. However, a blend of polyurethane or PVC with another polymer is only classified in D06N 3/142 or D06N 3/065, respectively.
When the coating composition is too generally defined, too many possibilities are disclosed or the product is used for other application than the ones defined in subgroups D06N 1/00, D06N 3/00, D06N 5/00, D06N 7/0002, D06N 7/0005 or D06N 7/0063, then subclasses corresponding to the compounds used in the examples are allocated. In absence of examples, the pertinent subgroups D06N 7/00 or D06N 7/0092 - D06N 7/0097 are given.
When the coating composition comprises a material not specified in the subgroups D06N 3/02 - D06N 3/16, e.g. starch, chitosan, classification is given in D06N 7/00 and D06N 2203/00.
In this group the use of Indexing Codes is mandatory to classify technical information belonging to the core of the invention as long as said technical information can not be classified in any of the subgroups and optional for the classification of additional information.
In this place, the following terms or expressions are used with the meaning indicated:
Fibrous web | Woven, non-woven, knitted or tufted fabric. |
Coated with a macromolecular material | Macromolecular material or polymer composition applied by e.g. brushing, flowing, sprinkling, spraying, doctor blading, casting or extruding a solution, dispersion, melt or paste. |
This place covers:
Floor coverings obtained by applying a linoleum composition onto a fibrous web.
This place covers:
Artificial leather.
Any polymer coated fibrous web, e.g. airbags, or wall or floor coverings, characterised by:
- the fibrous substrate,
- compounding ingredients of the macromolecular coating,
- polymer material,
- a foamed, cellular or perforated polymeric coating,
- mechanical or physical treatments taking place before, during or after application of the coating, or
- application technique of the polymeric coating.
This place does not cover:
Floor coverings comprising a fibrous substrate coated on the top surface with at least one layer of polymer characterised only by their relief structure, colour effects or physical or chemical aspects of the layers | |
Floor coverings comprising a fibrous top layer being coated at the back with at least one polymer layer, e.g. carpets, artificial turf, mats, rugs | |
Carpet underlays |
This place covers:
Coating compositions comprising polymers made exclusively from acrylic monomers.

The macromolecular materials of the different layers are additionally classified in the subgroups D06N 3/02 - D06N 3/16 or D06N 2203/00. If other additives of any of the compositions are important a classification should also be given in the pertinent subgroups D06N 3/0056.
This place covers:
Roofing materials or products that are useful as roofing material (specified in the claims or description) comprising a fibrous web coated with at least one layer of a macromolecular material, i.e. thermoplastic, elastomer, bitumen or asphalt.
In D06N 5/006 the fastening means should be part of the structure of the material, such as a strip of a self-adhesive at the edge of the roofing membrane or a meltable strip or layer allowing welding of the roofing membrane to a support or to another membrane.

Carpets, rugs, mats or artificial lawn characterised by the pile yarns, e.g. differently dyed, of different length, of at least two different materials.
Carpets, rugs, mats or artificial lawn, wherein the pile yarns are fused, soften or melted at the back of the primary backing should be classified in this subgroup, independently if a back coating is also present or not.
If the material of the pile yarn is important the pertinent Indexing Code in D06N 2201/00 should also be given.
This place covers:
Carpets, rugs, mats or artificial lawn characterised by their backing, e.g. pre-coat, back coating, stabilizing layers, secondary backing, cushion backing.
If the material of the components of the backing is important classification should also be given in the pertinent Indexing Codes.
This place does not cover:
Carpets, rugs, mats or artificial lawn, wherein the pre-coat or the back coating is made from a hot melt composition comprising at least a thermoplastic polymer and a tackifying resin. |
Sometimes the term "hot melt" is used to describe melt thermoplastics not containing tackifying resins. In this case classification is given in this group and not in D06N 7/0078.
When it is not clear whether the term "hot melt" means thermoplastic comprising or not a tackifying resin, then it is recommended to classify it in both this group and D06N 7/0078.
When it is not clear whether the term "hot melt" means thermoplastic comprising or not a tackifying resin, then it is recommended to classify it in both this group and D06N 7/0076.
In this place, the following terms or expressions are used with the meaning indicated:
