Abstract
Textile fabrics are dyed with a substance comprising a pigment or colorant and a latex serving as a binding agent or color agglutinant which bonds the pigment to the fabric. The latex is rendered thermally sensitive and hence is thermally activatable by the introduction of an alkylene-oxide/urethane copolymer.
Claims5
A process for the coloring of textiles which comprises the step of:
- treating the textile with a pigment dyestuff in a binding agent in the form of a latex and including a thermosensitizing agent constituted by an alkylene-urethane copolymer, the proportion of the alkylene-urethane copolymer with respect to the quantity of latex being between 2 and 80% by weight;
- and
- heating the treated textile to a temperature sufficient to activate said latex and bond said pigmentary colorant to said fabric.
