Abstract
Abstract The transfer printability of fabric materials containing at least a minor proportion of cellulosic or natural proteinaceous fibers such as, for example, cotton, rayon, cellulose acetate, wool, silk, etc. is notably improved by a treatment in which said fabric material is impregnated with certain glycoside reagents. Especially preferred glycoside reagents for use in such treatment are C 2 -C 6 alkyl monoglucosides.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
126 words
A method of imparting improved transfer printability to a textile fabric which is composed at least in part of cellulosic or natural proteinaceous fibers, said method comprising the step of impregnating said textile fabric with an effective amount of a glycoside reagent of the formula: RO(R'O).sub.y (Z).sub.x A wherein R is a monovalent organic radical containing from 2 to about 8 carbon atoms; O is an oxygen atom; R' is a divalent hydrocarbon radical containing from 2 to about 4 carbon atoms; y is a number having an average value of from 0 to about 12; Z represents a moiety derived from a reducing saccharide containing 5 or 6 carbon atoms; and x is a number having an average value of from 1 to about 5.
Claim 2
Independent Claim
126 words
A method of imparting improved transfer printability to a textile fabric which is composed at least in part of cellulosic or natural proteinaceous fibers, said method comprising the step of impregnating said textile fabric with an effective amount of a glycoside reagent of the formula: RO(R'O).sub.y (Z).sub.x A wherein R is a monovalent organic radical containing from 2 to about 8 carbon atoms; O is an oxygen atom; R' is a divalent hydrocarbon radical containing from 2 to about 4 carbon atoms; y is a number having an average value of from 0 to about 12; Z represents a moiety derived from a reducing saccharide containing 5 or 6 carbon atoms; and x is a number having an average value of from 1 to about 5.
Claim 3
Dependent Claim
41 words
The method of claim 1 wherein y is 0, Z is a glucose moiety, R is an alkyl or hydroxyalkyl group having from 2 to about 6 carbon atoms and x has an average value of from 1 to about 3.
Claim 4
Dependent Claim
19 words
The method of claim 2 wherein R is an alkyl group containing from 2 to about 6 carbon atoms.
Claim 5
Dependent Claim
17 words
The method of claim 3 wherein x has an average value of from 1 to about 1.5.
Claim 6
Dependent Claim
11 words
The method of claim 4 wherein R is an n-butyl group.
Claim 7
Dependent Claim
34 words
The method of claim 1 wherein the textile fabric is impregnated with the glycoside reagent by contacting said fabric with an aqueous solution of said glycoside reagent and thereafter drying the impregnated textile fabric.
Claim 8
Dependent Claim
23 words
The method of claim 6 wherein the glycoside reagent constitutes from about 1 to about 20 weight percent of the aqueous glycoside solution.
Claim 9
Dependent Claim
44 words
The method of claim 6 wherein, on a dry solids weight basis, from about 1 to about 10 parts of the glycoside reagent is impregnated into said textile fabric for every 100 parts by weight of said fabric treated in accordance with said method.
Claim 10
Dependent Claim
17 words
The method of claim 8 wherein said fabric is sprayed with said aqueous solution of glycoside reagent.
Claim 11
Dependent Claim
15 words
The method of claim 8 wherein said fabric is immersed in said aqueous glycoside solution.
Claim 12
Dependent Claim
19 words
The method of claim 6 wherein the textile fabric is composed of a blend of polyester and cotton fibers.
Claim 13
Dependent Claim
13 words
The method of claim 6 wherein the textile fabric consists essentially of cotton.
Claim 14
Dependent Claim
125 words
A treated fabric material which is composed at least in part of cellulosic or natural proteinaceous fibers and which has distributed therein, on a dry fabric substrate weight basis, from about 0.5 to about 20 weight percent of a glycoside reagent of the formula: RO(R'O).sub.y (Z).sub.x A wherein R is a monovalent organic radical containing from 2 to about 8 carbon atoms; O is an oxygen atom: R' is a divalent hydrocarbon radical containing from 2 to about 4 carbon atoms; y is a number having an average value of from 0 to about 12; Z represents a moiety derived from a reducing saccharide containing 5 or 6 carbon atoms; and x is a number having an average value of from 1 to about 5.
Claim 15
Dependent Claim
