Class 008 :: BLEACHING AND DYEING; FLUID TREATMENT AND CHEMICAL MODIFICATION OF TEXTILES AND FIBERS

Definition

This class takes the characters of processes set forth below, the products of such processes where not more specifically provided for, 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 compositions for dyeing materials of any kind (subclasses 400-696), including specific treatments peculiarly related to dyeing, such as mordanting, weighting, color protecting, etc. In subclasses 400-696 the main line subclass title indicates whether the particular subclass and its indents are limited to processes, compositions, etc., or combinations of such. In instances where subject matter proper for subclasses 400-696 is combined with subject matter proper for other main classes, unless contraindicated elsewhere, if the dye steps are followed by subject matter proper for another main class the combination is classified in the other class and cross-referenced here. Dyeing steps following or simultaneous with steps proper for other classes are generally classified here.

This is the generic class for processes of and compositions for treating hides, skins, feathers and animal tissues with chemicals and fluids (see References to This Class, below).

This is the generic class for processes of bleaching materials of any kind (see References to This Class, below).

This is the generic class for processes of and compositions for 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 of textiles and organic fibers and takes compositions for this purpose when not more specifically provided for elsewhere e.g., parchmentizing and mercerizing compositions (see References to This Class, below).

This is also the class for special types of processes for treating textiles and fibers with fluids even though the fluids do not chemically modify the textiles and fibers, namely:

(a) plasticizing or swelling of artificial fibers whether or not combined with stretching;

(b) fiber protecting during treatments provided for in this class;

(c) color protecting during treatments provided for in this class);

(d) cleaning and laundering (see References to This Class, below).

Manipulative processes for the treatment of textile fibers of fabrics, hides, skins and leather with chemicals and fluids for a purpose provided for in this class which are of general applicability are placed in this class, even though limited by claim terminology to 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 or product, classifiable in this class, is claimed along with claims to apparatus, the patent is placed in this class

(8) and cross referenced to the appropriate apparatus class.

LINES WITH OTHER CLASSESFor coloring of plastic materials by incorporation of coloring matter in solution or plastic composition before shaping, see the appropriate classes, e.g., Class 106; Class 252; Class 260; etc.

The printing compositions employed in this class are basically distinguished from the printing inks of Class 106, Compositions: Coating or Plastic, in that the latter are intended essentially for coating the surface of a material in patterns or designs, while in this class the coloration is produced by imbibition and absorption by or combination with the fibers of the material. Class 106 usually involves an insoluble pigment suspended in an oleaginous vehicle, while here a soluble dye in an aqueous paste is usually involved.

The rules for determining Class placement of the Original Reference (OR) for claimed chemical compositions are set forth in the Class Definition of Class 252 in the section LINES WITH OTHER CLASSES AND WITHIN THIS CLASS, subsection COMPOSITION CLASS SUPERIORITY, which includes a hierarchical ORDER OF SUPERIORITY FOR COMPOSITION CLASSES.
