Abstract
Abstract The present invention relates to a textile method of continuously dyeing a fibrous material and particularly a pile fabric which includes the steps of applying a foam containing a dye to the fiber or fabric, subjecting the foam treated material to a steaming operation to effect fixation of the dye, and washing the dyed material. The apparatus includes means for producing a foam, containing a dye, a tank for containing the foam and immersing the material to be dyed therein, a steamer that is in direct communication with the foam tank, and a wash box that receives the steamed material directly into its water bath without subjecting the dyed material to the atmosphere.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
203 words
A method of continuously uniformly dyeing textile fibrous material comprising the steps of: a. producing a large body of homogeneous foam at a pressure above atmospheric pressure, said foam containing a dye and a wetting agent and a biphenyl solvent; b. dispensing said foam at atmospheric pressure by foam dispensing means; c. receiving said foam from said dispensing means in a foam dye box vented to the atmosphere; d. positioning said foam dispensing means above said box such that said foam is discharged into said box; e. immersing said material in said foam and running said material repeatedly upwardly and downwardly through said foam at atmospheric pressure to effect penetration of said foam into said material, said material being continuously conveyed by roller means including at least one roller positioned in said box; f. transversely reciprocating said dispensing means across the breadth of said box whereby said foam is discharged into said box at a level such that said roller is covered by said foam; g. removing a predetermined amount of said foam from said material upon exit of said material from said foam by adjustable means; and h. effecting fixation of said dye on said foam penetrated material by steaming said material.
Claim 2
Independent Claim
203 words
A method of continuously uniformly dyeing textile fibrous material comprising the steps of: a. producing a large body of homogeneous foam at a pressure above atmospheric pressure, said foam containing a dye and a wetting agent and a biphenyl solvent; b. dispensing said foam at atmospheric pressure by foam dispensing means; c. receiving said foam from said dispensing means in a foam dye box vented to the atmosphere; d. positioning said foam dispensing means above said box such that said foam is discharged into said box; e. immersing said material in said foam and running said material repeatedly upwardly and downwardly through said foam at atmospheric pressure to effect penetration of said foam into said material, said material being continuously conveyed by roller means including at least one roller positioned in said box; f. transversely reciprocating said dispensing means across the breadth of said box whereby said foam is discharged into said box at a level such that said roller is covered by said foam; g. removing a predetermined amount of said foam from said material upon exit of said material from said foam by adjustable means; and h. effecting fixation of said dye on said foam penetrated material by steaming said material.
Claim 3
Dependent Claim
29 words

A method of continuously uniformly dyeing textile fibrous material according to claim 1 further including the step of maintaining said foam within a specific gravity range of 0.2 to 0.3.
Claim 6
Dependent Claim
24 words
A method of continuously uniformly dyeing textile fibrous material according to claim 1 and further characterized by the step of washing said dyed material.
