English 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.


Claims

Note: Claims are shown in the official language in which they were submitted.



THE EMBODIMENTS OF THE INVENTION IN WHICH AN EXCLUSIVE
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.

~ 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.

The preferred mode of proced.ure is as
describ6d in specifica-tion 1 284 824 and the following
is an example of a padding medium supplied as a
` powder.

Diaprint Reg. 10 parts ..
Citric Acid and/or
Potassium Hydrogen

`~ 10. To prepare for use, mix 4.4 parts powder
wi-th 95.6 parts water at 60 - 80C. Cool to room
temperature and evenly impregnate the fabric with
, this paste in the proportion of 2.5 parts to 1 part of
`! ~abric.
