An apparatus and method for selectively carving textile fabric (12) by selectively applying chemicals containing a liquid repellant either alone or with a colorant such as a dye to a textile fabric and subsequently drying said fabric. The textile fabric (12) from a supply toll (18) passes over an idler roll (32) and into a dyeing apparatus (16). The dyeing apparatus (16) includes a mesh print screen (20) and a squeegee (21). The mesh print screen is opposite a support roll (26) with the textile fabric (12) passing therebetween. The chemicals from the mesh print screen are applied in a selectively patterned arrangement. The textile fabric (12) then passes into a finishing apparatus (34) that typically includes a hot air oven. The textile fabric (12) then moves to a take-up toll (14) for collection.

Cette invention concerne un appareil et un procédé permettant d'imprimer de façon sélective des tissus textiles (12), lequel procédé consiste à appliquer de façon sélective sur un tissu textile des agents chimiques contenant un répulsif liquide seul ou en combinaison avec un colorant tel qu'une teinture, puis à faire sécher ledit tissu. Le tissu textile (12) provenant d'un rouleau débiteur (18) passe sur un rouleau fou (32), puis dans un appareil de teinture (16). Cet appareil de teinture (16) comprend un imprimeur sérigraphe à mailles (20) ainsi qu'une raclette (21). L'imprimeur sérigraphe à mailles est situé face à un cylindre de support (26), le tissu textile (12) passant entre ces derniers. Les agents chimiques venant de l'imprimeur sérigraphe à mailles sont appliqués selon une disposition configurée sélectivement. Le tissu textile (12) passe ensuite dans un appareil de finition (34), lequel comprend typiquement un four à air chaud. Le tissu textile (12) est ensuite dirigé vers un cylindre récepteur (14) où il sera enroulé.
