DEFINITION

Classification: 252/8.86

For textile materials consisting wholly or in part of silk or cellulose-based fibers (e.g., cotton; artificial silk, such as rayon, cellulose acetate, etc., or blends thereof; silk soaking compositions; etc.):

(under subclass 8.81) Compositions wherein the textile material includes or consists of silk fibers or fibers of cellulose or its derivatives.

(1) Note. Fibers made of regenerated cellulose (e.g., rayon) or of cellulose esters or ethers, such as cellulose acetate, are sometimes referred to as semisynthetic fibers or artificial silk.

(2) Note. Included in this subclass are blends of any one or more fibers with any other fiber under the subclass definition, such as linen, jute, hemp, etc.).

(3) Note. Many compositions in this subclass facilitate processing by softening (making more flexible) the above fibers or materials made therefrom.
