DEFINITION

Classification: 8/529

MULTIPLE CHEMICALLY DIVERSE FIBERS OR FIBERS WITH DIFFERENT CROSS SECTION, PROCESS OF DYEING OR PRODUCT:

(under the class definition) Subject matter relating to processes for coloring textile materials composed of more than one kind of fiber in solid or contrast shades and the preparation of the colored effect threads for a mixed fabric or product thereof.

(1) Note. Dyeing of mixed fiber fabric followed by complete discharge of the dye from one of the components of the mixed material is in this subclass.

(2) Note. Fiber blends herein means a mixture of diverse fibers and does not mean a blend of polymers in a single fiber.
