WARNING

The following IPC groups are not used in the CPC scheme. Subject-matter covered by these groups is classified in the following CPC groups: - D03C9/04 covered by D03C 9/028

D03D

WOVEN FABRICS; METHODS OF WEAVING; LOOMS

NOTE

Class D06 takes precedence over this subclass in respect of processes involving both weaving and finishing steps and in respect of the finished fabrics.

A method of weaving is classified in the group designating the fabric woven unless the method is characterised by the operation of a particular loom rather than by the production of a particular fabric. In this case, the method is classified in the group for the loom.

In this subclass, if there is any doubt as to which of the essential features is the most important (this is usually the most restrictive feature), the groups designating woven fabrics should be considered in the order in which they appear at each level of indentation, except that groups designating woven pile fabrics are to be considered as taking precedence over groups designating other woven fabrics.

D03J

AUXILIARY WEAVING APPARATUS; WEAVERS` TOOLS; SHUTTLES

D04

BRAIDING; LACE-MAKING; KNITTING; TRIMMINGS; NON-WOVEN FABRICS

D04B

NOTE

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.

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.

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.

In this subclass, a number of groups, e.g. D04H 1/067, correspond to IPC2012.01

INDEXING SCHEME ASSOCIATED WITH SUBLASSES OF SECTION D, RELATING TO TEXTILES

NOTE

This subclass constitutes a scheme for indexing only.

The indexing codes of this subclass, relating to the chemical constitution of the fibrous materials, are to be associated with groups of section D, with the exception of those of subclass D06M, as far as these groups themselves do not give information about the chemical nature of the fibres.
