DEFINITION

Classification: 264/198

(under subclass 188) Processes wherein the formed viscose article is subjected to a subsequent mechanical working or shaping step.

(1) Note. Since stretching is a conventional operation in the formation of indefinite length articles, a search in appropriate subclasses above will be necessary where an article forming operation combined with a nominally recited stretching step is set out in a viscose process. However, a patent classified above disclosing or claiming a significant stretching step in a viscose process will be crossed here.

SEE OR SEARCH THIS CLASS, SUBCLASS:

197, for stretching of indefinite length viscose articles following a plural step coagulation or regeneration.

208, for stretching of cellulose articles formed by an evaporative method.

210, for stretching of articles formed by melt spinning.

288, for stretching of preformed running length work.
