Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
50 words
A PROCESS FOR RINSING OR WASHING AND DRYING OF TEXTILE MATERIAL, COMPRISING TREATING THE MATERIAL IN AN AQUEOUS BATH, SAID BATH CONSISTING ESSENTIALLY OF AN AQUEOUS RINSE OR WASH LIQUID AND A BURNABLE ORGANIC SOLVENT, AND DRYING AND REMOVING THE LIQUID FROM THE MATERIAL BY BURNING OFF THE ORGANIC SOLVENT.
Claim 2
Dependent Claim
50 words
A PROCESS FOR RINSING OR WASHING AND DRYING OF TEXTILE MATERIAL, COMPRISING TREATING THE MATERIAL IN AN AQUEOUS BATH, SAID BATH CONSISTING ESSENTIALLY OF AN AQUEOUS RINSE OR WASH LIQUID AND A BURNABLE ORGANIC SOLVENT, AND DRYING AND REMOVING THE LIQUID FROM THE MATERIAL BY BURNING OFF THE ORGANIC SOLVENT.
Claim 3
Dependent Claim
22 words
The process of claim 1, wherein the wash or rinse liquid contains a monohydric hydrocarbon alcohol having 1 to 3 carbon atoms.
Claim 4
Dependent Claim
31 words
The process of claim 1, in which the wash or rinse liquid contains between 10 and 90% by volume of the burnable solvent and 90 to 10% by volume of water.
Claim 5
Dependent Claim
47 words
The process of claim 3, in which prior to the burning step, the material to be treated and the aqueous liquid are cooled to temperatures below the ignition point of the liquid on the material and are maintained at these temperatures until the ignition of the solvent.
Claim 6
Dependent Claim
35 words
The process of claim 4, wherein the burnable solvent on the material, prior to the burning step, is maintained at a temperature of about 1* to 40*C below the ignition point of the burnable solvent.
Claim 7
Dependent Claim
25 words
The process of claim 1, wherein burning off the solvent and removing the liquid from the material is carried out with the addition of heat.
Claim 8
Dependent Claim
31 words
The process of claim 6, in which the burning off of the solvent and the removal of the liquid from the material is carried out on one side of the material.
Claim 9
Dependent Claim
17 words
The process of claim 1, wherein the heat released in the burning process is used for drying.
Claim 10
Dependent Claim
24 words
The process of claim 1 wherein the heat released in the burning process together with heat that is supplied is used for the drying.
Claim 11
Dependent Claim
42 words
A process for washing or rinsing and drying a textile material, consisting essentially of washing or rinsing the material in an aqueous bath and applying to the material a burnable organic solvent and drying the material by burning off the organic solvent.
Claim 12
Dependent Claim
42 words
A process for washing or rinsing and drying a textile material, consisting essentially of washing or rinsing the material in an aqueous bath and applying to the material a burnable organic solvent and drying the material by burning off the organic solvent.
Claim 13
Dependent Claim
22 words
The process of claim 10 wherein the aqueous bath consists essentially of an aqueous rinse or wash liquid and the organic solvent.
Claim 14
Dependent Claim
21 words
The process of claim 10 wherein the Organic solvent is applied to the material after the aqueous wash or rinse bath.
Claim 15
Dependent Claim
91 words
A process for rinsing or washing and drying of textile materials consisting of natural or synthetic fibers or a mixture thereof comprising treating the material in an aqueous bath, said aqueous bath consisting essentially of an aqueous rinse or wash liquid and a burnable organic solvent, the organic solvent selected from the group consisting of a hydrocarbon monohydric alcohol containing one to three carbon atoms, dioxane and a mixture thereof and drying the textile material and removing the rinse or wash liquid from the material by burning off the organic solvent.
Claim 16
Dependent Claim
91 words
A process for rinsing or washing and drying of textile materials consisting of natural or synthetic fibers or a mixture thereof comprising treating the material in an aqueous bath, said aqueous bath consisting essentially of an aqueous rinse or wash liquid and a burnable organic solvent, the organic solvent selected from the group consisting of a hydrocarbon monohydric alcohol containing one to three carbon atoms, dioxane and a mixture thereof and drying the textile material and removing the rinse or wash liquid from the material by burning off the organic solvent.
Claim 17
Dependent Claim
32 words
The process of claim 13 wherein the aqueous bath organic solvent mixture consists of between 10 and 90% by volume of the organic solvent and 90 to 10% by volume of water.
Claim 18
Dependent Claim
11 words
The process of claim 13 wherein the organic solvent is methanol.
