A process for patterning textile materials is described. The process involves applying a water soluble chemical substance designed to mechanically inhibit the wetting of underlying regions of the fabric to a textile fabric in a predetermined pattern, then dyeing the fabric in a manner conventionnally used to uniformly dye fabrics, such as by a continuous or semi-continuous dye process. The chemical substance which has been applied to the fabric functions to temporarily mechanically inhibit wetting of the underlying regions of the fabric, so that the underlying portions are dyed to a lesser extent than the surrounding regions. The resulting fabrics have good print characteristics without the physical strength degradation of irregular hand associated with patterned fabrics produced by conventional fabric patterning methods.

L'invention concerne un procédé de formation de motifs sur des matériaux textiles. Ce procédé consiste à appliquer une substance chimique hydrosoluble conçue pour inhiber de façon mécanique le mouillage des zones sous-jacentes du tissu sur un textile selon un motif prédéterminé, à ensuite teindre le tissu selon un procédé utilisé conventionnellement pour teindre uniformément des tissus, tel qu'un procédé de teinture continue ou semi-continue. La substance chimique appliquée sur le tissu inhibe temporairement, de façon mécanique, le mouillage de zones sous-jacentes du tissu, de manière que les parties sous-jacentes soient teintes dans une moindre mesure que les zones qui les entourent. Les tissus résultants possèdent de bonnes caractéristiques d'impression sans la dégradation irrégulière de la résistance mécanique qui est associée à des tissus à motifs produits selon des procédés conventionnels de formation de motifs.
