Abstract
Abstract Process and apparatus for the pattern dyeing of moving pile fabrics such as carpets, by the application of plural, continuously flowing dye streams, wherein the dyes are applied in multiple discrete small increments from the streams and control means are provided for accurately positioning the points of application of the dye increments in the pile fabrics to obtain sharp, detailed intricate patterns.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
82 words
A method of dyeing a porous textile material, in particular pile fabrics and carpets, to obtain a desired pattern thereon with apparatus including conveying means for transporting the textile material past at least one row of jet orifices extending across the path of the textile material, deflecting means associated with said jet orifices, pattern control means to supply pattern data to control the operation of said deflecting means, and said pattern control means including timing means; said method comprising the steps of
Claim 2
Independent Claim
82 words
A method of dyeing a porous textile material, in particular pile fabrics and carpets, to obtain a desired pattern thereon with apparatus including conveying means for transporting the textile material past at least one row of jet orifices extending across the path of the textile material, deflecting means associated with said jet orifices, pattern control means to supply pattern data to control the operation of said deflecting means, and said pattern control means including timing means; said method comprising the steps of
Claim 3
Dependent Claim
137 words
transmitting pattern data from said pattern control means to said deflecting means in a multiplicity of repeating cycles (E-E) so that continuous dye streams from the jet orifices are directed onto or away from the textile material as required to form a single pattern, 2. initiating each of said cycles in response to movement of the textile material through a predetermined, preselected incremental distance, 3. directing one or more of the dye streams onto the textile material during one or more time controlled segments (C) of preselected duration within a fixed time period (T) in selected cycles in accordance with said pattern data and the operation of said timing means, and 4. maintaining within each cycle a quiescent time (Q) during which all of said dye streams in the row are directed away from the textile material.
Claim 4
Dependent Claim
137 words
transmitting pattern data from said pattern control means to said deflecting means in a multiplicity of repeating cycles (E-E) so that continuous dye streams from the jet orifices are directed onto or away from the textile material as required to form a single pattern, 2. initiating each of said cycles in response to movement of the textile material through a predetermined, preselected incremental distance, 3. directing one or more of the dye streams onto the textile material during one or more time controlled segments (C) of preselected duration within a fixed time period (T) in selected cycles in accordance with said pattern data and the operation of said timing means, and 4. maintaining within each cycle a quiescent time (Q) during which all of said dye streams in the row are directed away from the textile material.
Claim 5
Dependent Claim
69 words
A method as defined in claim 1 wherein the textile material is a length of tufted pile carpet material from which a multiplicity of area rugs may be cut, the specific pattern being an area rug pattern, and the entire pattern is applied to successive portions of the length of the tufted carpet material while it moves continuously past said orifices and thereafter through a succession of finishing processes.
Claim 6
Dependent Claim
9 words
A product produced by the method of claim 2.
Claim 7
Dependent Claim
21 words
A method as defined in claim 1 wherein an area of single color is dyed in a multiplicity of repeating cycles.
Claim 8
Dependent Claim
21 words
A method as defined in claim 1 wherein the direction of each dye stream onto the textile material is individually controlled.
Claim 9
Dependent Claim
23 words
A method as defined in claim 1 wherein the predetermined, preselected incremental movement of the textile material is uniform from cycle to cycle.
Claim 10
Dependent Claim
30 words
A method as defined in claim 1 wherein the length of the quiescent time provided in each cycle is at least equal to the recovery time of the deflecting means.
Claim 11
Dependent Claim
38 words
A method as defined in claim 1 wherein the textile material is a pile fabric and wherein the predetermined, preselected incremental movement of the textile material is approximately the distance between pile elements along the direction of movement.
Claim 12
Dependent Claim
34 words
A method as defined in claim 8 wherein said fixed time period in each cycle is selected to provide sufficient dye to said pile element of the fabric to dye substantially its full height.
Claim 13
Dependent Claim
38 words
A method as defined in claim 9 including the step of providing substantially the same number of dye streams in said row as the number of pile elements in the fabric disposed transversely to its direction of movement.
Claim 14
Dependent Claim
9 words
A product produced by the method of claim 9.
Claim 15
Dependent Claim
11 words
A multicolored pile fabric produced by the method of claim 11.
Claim 16
Dependent Claim
37 words
A method as defined in claim 9 wherein the material is dyed by application of a spaced plurality of rows of orifices, and the dye streams of each of said rows are controlled in the manner defined.
Claim 17
Dependent Claim
31 words
A method as defined in claim 13 wherein the fixed time period in which the dye streams are directed onto the textile material is of different duration from row to row.
Claim 18
Dependent Claim
19 words
A method as defined in claim 1 wherein the dye streams are continuously discharged from the orifices under pressure.
