Abstract
ABSTRACT OF THE DISCLOSURE
For the transference of dyes from paper onto textile fabrics, using a heated press at a temperature between 80°C to 120°C at a pressure of up to 10 lbs.
per square inch, and for a period not exceeding 10 minutes, whereafter the printed fabric or material is removed from the press, washed and dried, it is proposed to preliminarily treat the textile fabric with a padding material comprised of citric acid and/or potassium hydrogen sulphate and a printing paste thickener.

Description
~ Z5~
This invention relates to a method of transferring dyes from paper onto textile fabrics and represents an improve-ment in or modification oE a preferred mode of performance of the method disclosed in our British Patent 1,284,824.
Accor~ing to that Patent there was proposed a method of transferring dyes which comprised transferring coloured dyes from a paper roll onto a padded textile fabric or material of animal fibres, using a heated press at a temperature between 80C to 120C at a pressure of up to 10 lbs. per square inch, and for a period not exceeding 10 minutes, the printed fabric or material being then removed from the press, washed in water and dried.
The padding on the textile fabric preferably comprised ~-sulphamic acid as an aqueous acidic li~uid phase and a printing paste thickener which is stable under acid conditions, for example a locust bean derivat1ve.
It has however now been discovered that the padding medium may instead comprise citric acid and/or potassium hydrogen -sulphate as an alternative to sulphamic acid.
.
; 20 ~ When used together the preferred ratio between citric acld ~and potassium hydroyen sulphate will normally be in the range 3:2 to 2:3 with a preferred ratio of 1:1.

Claims (3)
PROPERTY OR PRIVILEGE IS CLAIMED ARE DEFINED AS FOLLOWS:
1. A method of transferring dyes which comprises transferring coloured dyes from a paper roll onto a textile fabric or material of animal fibres which has been padded with a composition comprising citric acid and/or potassium hydrogen sulphate, and a printing paste thickener which is stable under acid conditions, using a heated press at a temperature between 80°C to 120°C at a pressure of up to 10 lbs. per square inch, and for a period not exceeding 10 minutes, the printed fabric or material being then removed from the press washed in water and dried.
2. A method as claimed in claim 1 in which the composition contains citric acid and potassium hydrogen sulphate in the ratio range 3:2 to 2:3.
3. A method as claimed in claim 1 in which the composition contains citric acid and potassium hydrogen sulphate in the ratio 1:1.
