DEFINITION

Classification: 8/491

OVERALL DIMENSIONAL MODIFICATION OR STABILIZATION, E.G., CREPING, ETC., INCLUDING USE OF CHEMICAL ADDITIVE TO FORM AT LEAST A TEMPORARY COMPOSITION, WITH DYEING PROCESS:

(under the class definition) Processes involving an overall dimensional modification or stabilization of the substrate (including use of a chemical additive to form a treating composition) and dyeing.

(1) Note. The treating can be physical, e.g., shrinking, heat setting, creping, etc., or it can be by a chemical additive.

(2) Note. Creping refers to several methods of producing a crepe effect on a fabric. See the Glossary for a definition of crepe.
