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: 13
Claim 1
Independent Claim
201 words
A method of transfer printing a textile fabric which is composed at least in part of cellulosic or natural proteinaceous fibers, said method comprising the steps of: (a) saturating said textile fabric with an aqueous solution comprising a glycoside reagent of the formula: RO(R'O).sub.y (Z).sub.x A wherein R is 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; (b) drying the resulting saturated textile fabric thereby providing a substantially dry, impregnated textile fabric; and (c) transfer printing onto the dried, impregnated textile fabric by contacting said fabric with a transfer printing paper containing a coating of a disperse dye composition thereon at an elevated temperature for a time sufficient to cause at least a portion of the disperse dye composition to vaporize and to migrate from the surface of the printing paper to the textile fabric.
Claim 2
Independent Claim
201 words
A method of transfer printing a textile fabric which is composed at least in part of cellulosic or natural proteinaceous fibers, said method comprising the steps of: (a) saturating said textile fabric with an aqueous solution comprising a glycoside reagent of the formula: RO(R'O).sub.y (Z).sub.x A wherein R is 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; (b) drying the resulting saturated textile fabric thereby providing a substantially dry, impregnated textile fabric; and (c) transfer printing onto the dried, impregnated textile fabric by contacting said fabric with a transfer printing paper containing a coating of a disperse dye composition thereon at an elevated temperature for a time sufficient to cause at least a portion of the disperse dye composition to vaporize and to migrate from the surface of the printing paper to the textile fabric.
Claim 3
Dependent Claim
41 words

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

Claim 7
Dependent Claim
25 words
The method of claim 1 wherein the glycoside reagent constitutes from about 1 to about 20 weight percent of the aqueous lower alkyl glycoside solution.
Claim 8
Dependent Claim
44 words
The method of claim 1 wherein, on a dry solids weight basis, from about 2 to about 8 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 9
Dependent Claim
15 words
The method of claim 1 wherein said fabric is sprayed with said aqueous glycoside solution.
Claim 10
Dependent Claim
17 words
The method of claim 1 wherein said fabric is immersed in said aqueous lower alkyl glycoside solution.
Claim 11
Dependent Claim
19 words
The method of claim 1 wherein the textile fabric is composed of a blend of polyester and cotton fibers.
Claim 12
Dependent Claim
13 words
The method of claim 1 wherein the textile fabric consists essentially of cotton.
Claim 13
Dependent Claim
22 words
The method of claim 1 wherein transfer printing step is conducted at a temperature of from about 175° to about 210° C.
