Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
72 words
A process of fixing a dye or finishing substance applied to textile material of synthetic or natural fibres, said process comprising applying to such material an aqueous solution or dispersion of said substance; and subsequently exposing said material to air enriched with halogenated hydrocarbon having a boiling point below 85° C, the exposure to the enriched air occuring at a temperature not exceeding 30° C and prior to drying of said material.
Claim 2
Dependent Claim
72 words
A process of fixing a dye or finishing substance applied to textile material of synthetic or natural fibres, said process comprising applying to such material an aqueous solution or dispersion of said substance; and subsequently exposing said material to air enriched with halogenated hydrocarbon having a boiling point below 85° C, the exposure to the enriched air occuring at a temperature not exceeding 30° C and prior to drying of said material.
Claim 3
Dependent Claim
13 words
The process according to claim 1 wherein the enriched air is continuously circulated.
Claim 4
Dependent Claim
27 words
The process according to claim 1 wherein the exposure of said material to the enriched air occurs immediately following the application of said liquor to said material.
Claim 5
Dependent Claim
35 words
The process according to claim 1 wherein the exposure of said material to the enriched air occurs a sufficient time after the application of said liquor to said material to permit homogenization of said liquor.
Claim 6
Dependent Claim
24 words
The process according to claim 1 wherein said halogenated hydrocarbon is a halogenated derivative of methane or a halogenated derivative of ethane and ethylene.
Claim 7
Dependent Claim
22 words
The process according to claim 1 wherein said halogenated hydrocarbon is one in which only two H atoms are substituted by halogens.
Claim 8
Dependent Claim
13 words
The process according to claim 1 wherein said halogenated hydrocarbon comprises methylene chloride.
Claim 9
Dependent Claim
18 words
The process according to claim 1 wherein said air is enriched by passing it through liquid halogenated hydrocarbon.
Claim 10
Dependent Claim
14 words
The process according to claim 8 wherein the air also is enriched with water.
Claim 11
Dependent Claim
28 words
The process according to claim 1 wherein the material to which said liquor has been applied is subjected to vacuum prior to its exposure to the enriched air.
Claim 12
Dependent Claim
32 words
The process according to claim 1 including removing halogenated hydrocarbon from said material by subjecting the latter to steam or hot water following the exposure of said material to the enriched air.
Claim 13
Dependent Claim
21 words
The process according to claim 1 wherein said liquor contains an ionic dye having a high solubility in said halogenated hydrocarbon.
Claim 14
Dependent Claim
12 words
The process according to claim 1 wherein said material contains cellulosic fibres.
Claim 15
Dependent Claim
12 words
The process according to claim 1 wherein said material contains wool fibres.
Claim 16
Dependent Claim
24 words
The process according to claim 1 wherein said liquor contains a polar solvent to exert a swelling effect on the fibres of said material.
Claim 17
Dependent Claim
17 words
The process according to claim 15 wherein said polar solvent is selected from benzyl and n-butyl alcohols.
Claim 18
Dependent Claim
25 words
The process according to claim 15 wherein said polar solvent is selected from the class comprising ethylene carbonate, propylene carbonate, dimethyl formamide, and dimethyl acetamide.
Claim 19
Dependent Claim
50 words
A process of fixing a dye or finishing substance applied to textile material comprising polyester fibres, said process comprising applying to such material an aqueous solution or dispersion of said substance and subsequently exposing said material to air enriched with methylene chloride and having a temperature not exceeding 30° C.
Claim 20
Dependent Claim
50 words
A process of fixing a dye or finishing substance applied to textile material comprising polyester fibres, said process comprising applying to such material an aqueous solution or dispersion of said substance and subsequently exposing said material to air enriched with methylene chloride and having a temperature not exceeding 30° C.
