This class takes the characters of processes set forth below,the products of such processes where not more specifically providedfor, and in the specified instances, compositions used in the processes.(Also see References to Other Classes, below.)
This is the generic class for processes of and compositionsfor dyeing materials of any kind (subclasses 400-696), includingspecific treatments peculiarly related to dyeing, such as mordanting,weighting, color protecting, etc. In subclasses 400-696 the mainline subclass title indicates whether the particular subclass andits indents are limited to processes, compositions, etc., or combinationsof such. In instances where subject matter proper for subclasses400-696 is combined with subject matter proper for other main classes,unless contraindicated elsewhere, if the dye steps are followedby subject matter proper for another main class the combinationis classified in the other class and cross-referenced here. Dyeingsteps following or simultaneous with steps proper for other classesare generally classified here.
This is the generic class for processes of and compositionsfor treating hides, skins, feathers and animal tissues with chemicalsand fluids (see References to This Class, below).
This is the generic class for processes of bleaching materialsof any kind (see References to This Class, below).
This is the generic class for processes of and compositionsfor improving felting properties of textile fibers, hair, fur, feathers,etc.,e.g., carroting (see References to This Class, below).
This is the generic class for the chemical modification oftextiles and organic fibers and takes compositions for this purposewhen not more specifically provided for elsewhere e.g., parchmentizingand mercerizing compositions (see References to This Class, below).
This is also the class for special types of processes for treatingtextiles and fibers with fluids even though the fluids do not chemicallymodify the textiles and fibers, namely: (a) plasticizing or swellingof artificial fibers whether or not combined with stretching; (b)fiber protecting during treatments provided for in this class; (c) colorprotecting during treatments provided for in this class); (d) cleaningand laundering (see References to This Class, below).
Manipulative processes for the treatment of textile fibersof fabrics, hides, skins and leather with chemicals and fluids fora purpose provided for in this class which are of general applicabilityare placed in this class, even though limited by claim terminologyto a particular treatment, e.g., dyeing, bleaching, tanning, etc.(See References to This Class, below).
This class has no apparatus, per se, but where a process orproduct, classifiable in this class, is claimed along with claimsto apparatus, the patent is placed in this class (8) and cross referencedto the appropriate apparatus class.
