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

WARNING
-

1. Documents of the complete subclass D04H including all subgroups are in the process of being reorganised to the new groups corresponding to the IPC 2012.01 classification scheme defined below.
