Processes for bleaching or decolorizing textile filaments, strands, yarns, or fabrics not elsewhere provided for.
(1) Note. Manipulative processes not restricted in their applicability to bleaching, although bleaching may appear in the claims are classified in subclasses 147+.
(2) Note. Bleaching in combination with performing some other treatment on the material is in subclasses 101+, unless elsewhere provided for. Bowking of vegetable fibers or the scouring of other fibers is found in subclasses 101+ and is
not cross referenced to subclass 139, except for specific novelty in the bowking or scouring step.
SEE OR SEARCH THIS CLASS, SUBCLASS:
107+, for bleaching by definite named chemicals.
137+, for bleaching as a step incidental to a cleaning or laundering operation.
648, and the notes thereto, for the bluing of textiles and compositions therefor.
SEE OR SEARCH CLASS 68, Textiles: Fluid Treating Apparatus, for apparatus for bleaching textile fibers and fabrics.
132, Toilet,
208, for a method of bleaching live human hair on the scalp which is more than the mere application of a composition.
134, Cleaning and Liquid Contact With Solids, for nonelectrolytic processes of bleaching metal, siliceous and calcareous bases.
162, Paper Making and Fiber Liberation, particularly
6, 7, 64 to 67, and 70+ for bleaching and chemically purifying of fibers or fibrous pulps (as distinguished from continuous filaments or strands, etc.) or undried waterlaid fibrous webs.
205, Electrolysis: Processes, Compositions Used Therein, and Methods of Preparing the Compostions,
690, for bleaching of fibrous organic material involving electrolysis.
252, Compositions,
186.1+, and 188.1+ for bleaching compositions in general and subclasses 189 to 193 for compositions for neutralizing the acidity or alkalinity of a previous bleaching or laundering operation. Claims in the form of a process consisting in the mere application of a novel composition are not regarded as process for the purpose of subclasses 101+, but are placed in Class 252.
424, Drug, Bio-Affecting and Body Treating Compositions,
62, for a bleaching composition intended for use on the living body (e.g., living hair). 426, Food, or Edible Material: Processes, Compositions, and Products.
