Total Claims: 26
Claim 1
Independent Claim
54 words
A PROCESS FOR THE IMPREGNATION OF A TEXTILE MATERIAL WITH A TEXTILE TREATING AGENT AND SUBSEQUENT DRYING OF THE TEXTILE MATERIAL COMPRISING TREATING THE TEXTILE MATERIAL WITH AN IMPREGNATING BATH, SAID BATH CONSISTING ESSENTIALLY OF A TEXTILE TREATING AGENT AND AN INFLAMMABLE ORGANIC LIQUID, AND DRYING SAID TEXTILE MATERIAL BY BURING OFF THE LIQUID.
Claim 2
Dependent Claim
54 words
A PROCESS FOR THE IMPREGNATION OF A TEXTILE MATERIAL WITH A TEXTILE TREATING AGENT AND SUBSEQUENT DRYING OF THE TEXTILE MATERIAL COMPRISING TREATING THE TEXTILE MATERIAL WITH AN IMPREGNATING BATH, SAID BATH CONSISTING ESSENTIALLY OF A TEXTILE TREATING AGENT AND AN INFLAMMABLE ORGANIC LIQUID, AND DRYING SAID TEXTILE MATERIAL BY BURING OFF THE LIQUID.
Claim 3
Dependent Claim
20 words
The process of claim 1, wherein the impregnating bath comprises a monohydric hydrocarbon alcohol having 1 to 3 carbon atoms.
Claim 4
Dependent Claim
25 words
The process of claim 1, wherein the impregnating bath comprises 10 to 90% by volume of alcohol and 90 to 10% by volume of water.
Claim 5
Dependent Claim

Claim 6
Dependent Claim
51 words
The process of claim 1, wherein the textile materials to be treated and the impregnation bath prior to the burning step are cooled to temperatures below the ignition point of the inflammable organic liquid in the impregnating bath and maintained at these temperatures until the ignition of the inflammable organic liquid.
Claim 7
Dependent Claim
37 words
The process of claim 5, wherein the inflammable liquid after impregnation onto the material, prior to the burning step, is at a temperature of about 1* to 40*C below the ignition temperature of the inflammable organic liquid.
Claim 8
Dependent Claim
17 words
The process of claim 1, wherein a dwelling step is provided between the impregnation and drying steps.
Claim 9
Dependent Claim
26 words
The process of claim 1, wherein the burning off of the organic inflammable liquid from the material is carried out with the supply of additional heat.
Claim 10
Dependent Claim
26 words
The process of claim 8, wherein the burning off of the organic inflammable liquid from the material is carried out on one side of said material.
Claim 11
Dependent Claim
19 words
The process of claim 1, wherein the heat released during the burning off is used for drying the material.
Claim 12
Dependent Claim
26 words
The process of claim 1 wherein the heat released during the burning off and heat supplied during the burning off are used for drying the material.
Claim 13
Dependent Claim
36 words
A process for treating textile material which consists essentially of applying to the textile material a textile treating agent and an inflammable organic liquid and subsequently drying the textile material by burning off the organic liquid.
Claim 14
Dependent Claim
36 words
A process for treating textile material which consists essentially of applying to the textile material a textile treating agent and an inflammable organic liquid and subsequently drying the textile material by burning off the organic liquid.
Claim 15
Dependent Claim
24 words
The process of claim 12 wherein the treating agent and the inflammable organic liquid are applied to the textile material in the same step.
Claim 16
Dependent Claim
44 words
The process of claim 12 wherein the textile treating agent is applied to the textile material and the inflammable organic liquid is subsequently applied to the textile material and the inflammable organic liquid is burned off from the textile material drying the textile material.
Claim 17
Dependent Claim
17 words

Claim 18
Dependent Claim
31 words
The process of claim 12 wherein the heat released during the burning off of the inflammable organic liquid fixes the treating agent in the textile material and dries the textile material.
Claim 19
Dependent Claim
38 words
A process for dyeing a textile material which consists essentially of applying dyestuffs to the textile material and applying an inflammable organic liquid to the material and subsequently drying the textile material by burning off the organic liquid.
Claim 20
Dependent Claim
38 words
A process for dyeing a textile material which consists essentially of applying dyestuffs to the textile material and applying an inflammable organic liquid to the material and subsequently drying the textile material by burning off the organic liquid.
Claim 21
Dependent Claim
23 words
