Abstract
Abstract The present invention relates to a method of continuously dyeing a fibrous material and particularly a textile 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: 4
Claim 1
Independent Claim
171 words
In an apparatus for continuously dyeing fibrous material, a dyeing station of the type wherein a dye is continuously uniformly applied to said material, wherein the improvement comprises: means for producing a foam containing a dye at a pressure above atmospheric pressure; means in communication with said producing means for dispensing said foam at atmospheric pressure a foam dye box vented to the atmosphere for receiving said foam from said dispensing means; roller means for continuously conveying said fibrous material through said foam within said box; said roller means including at least one roller positioned in said box; said dispensing means being positioned above said box such that said foam is discharged into said box; reciprocating means for 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; and adjustable means for removing a predetermined amount of said foam from said material upon exit of said matErial from said foam.
Claim 2
Dependent Claim
