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-vowen fabrics can also be regarded as "layered products" within the meaning of subclass Fulltext... Hierarchy... Expanded...B32B, and further classification in that subclass should be considered in accordance with the notes thereto;
in cases where the making of non-vowen 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.
