Abstract
Abstract An apparatus for the colouration of textile materials with a gaseous stream containing a dyestuff, or dyestuffs, in vapour form, which comprises means for passing a hot stream of inert gas over a dyestuff and means for allowing the resulting stream of gas containing dyestuff vapour to impinge on the textile material, in particular an apparatus comprising a reservoir for containing an inert gas under pressure, said reservoir being connected to a tube fitted with heaters, said tube containing a receptacle for the dyestuff, and the other end of the tube being fitted with a jet from which issues the stream of inert gas containing a dyestuff vapour. The apparatus is preferably used for colouring synthetic textile materials with volatile Disperse Dyestuffs.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
76 words
An apparatus for the colouration of textile materials with a gaseous stream containing a dyestuff in vapour form, which comprises a reservoir containing an inert gas under pressure connected to a tube fitted with heaters, said tube being in communication with a receptacle for the dyestuff, and one end of the tube being fitted with a jet the exit of which is in close proximity to the piece of textile material which is to be coloured.
Claim 2
Independent Claim
76 words
An apparatus for the colouration of textile materials with a gaseous stream containing a dyestuff in vapour form, which comprises a reservoir containing an inert gas under pressure connected to a tube fitted with heaters, said tube being in communication with a receptacle for the dyestuff, and one end of the tube being fitted with a jet the exit of which is in close proximity to the piece of textile material which is to be coloured.
Claim 3
Dependent Claim
22 words
An apparatus as claimed in claim 1 which additionally contains means for transporting the textile material past the exit of the jet.
Claim 4
Dependent Claim
84 words
An apparatus as claimed in claim 2 for producing uniform colourations on textile materials during relative movement between the apparatus and the textile material comprising a plurality of colouration units, as described in claim l, disposed in a row which extends transversely to the direction of movement of the textile material, said units being so disposed that the stream of inert gas containing dyestuff vapour issuing from each jet merge together to form a continuous line extending across the width of the textile material.
Claim 5
Independent Claim
113 words
An apparatus for the colouration of textile materials with a dry inert gaseous stream containing a dyestuff in vapour form, which comprises: at least one tube having one end fitted with a jet nozzle the exit of which is to be placed in close proximity to a piece of textile material which is to be colored; means for supplying a dry inert gas, connected to the other end of said tube; heating means fitted to the tube for heating said tube; and a dyestuff receptacle connected to said tube so as to allow the surface of the dyestuff to be in communication with the interior of said tube and said inert dry gas.
Claim 6
Independent Claim
113 words
An apparatus for the colouration of textile materials with a dry inert gaseous stream containing a dyestuff in vapour form, which comprises: at least one tube having one end fitted with a jet nozzle the exit of which is to be placed in close proximity to a piece of textile material which is to be colored; means for supplying a dry inert gas, connected to the other end of said tube; heating means fitted to the tube for heating said tube; and a dyestuff receptacle connected to said tube so as to allow the surface of the dyestuff to be in communication with the interior of said tube and said inert dry gas.
Claim 7
Dependent Claim
146 words
Apparatus for the colouration of textile materials with a volatile dyestuff comprising: a receptacle, sealed from the atmosphere, for holding a quantity of a volatile dyestuff; means for heating the dyestuff in the receptacle in order to vaporize a portion of the dyestuff; means for mixing the dyestuff vapor in a stream of dry inert gas and for impinging the mixture onto a textile material, said means including at least one tube in communication with the receptacle, a nozzle fitted to one end of the tube and means fitted to the other end of the tube for supplying dry inert gas thereto, whereby a stream of mixed inert gas and dyestuff vapor may be discharged through the nozzle in the form of a jet; and means for supporting a textile material in the path of the jet so that the jet impinges on the textile material.
