Abstract
Disclosed herein is a process for coloring textile materials to produce random dyed effects wherein a coloring material is added to a foamed composition either before or after the foamed composition is coated onto a textile. The foam is then collapsed to penetrate the coloring material into the textile, and, finally, the textile is dried and cured or fixed.
Claims22
A method of coloring textile materials, comprising the steps of:
- (a) preparing a foamable composition comprised of a liquid and a foaming agent;
- (b) foaming said composition to a blow ratio of from about 2:1 to about 20:1 to form a foam having a density in the range of from about 0.05 gm/cc to about 0.5 gm/cc;
- (c) applying said foamed composition to a textile material;
- and
- (d) collapsing said foamed composition in contact with the textile material,
- wherein coloring material is added to said foamed composition of step (b) at a point in the method selected from:
- (1) prior to application of the foamed composition to the textile material;
- (2) during application of the foamed composition to the textile material;
- and (3) after application of the foamed composition to the textile material, the collapsing of the foamed composition, containing coloring material, causing penetration of the coloring material into the textile material.
