Abstract
A process for the treatment of textile materials, such as woven fabrics, with finishing agents such as dyestuffs, waterproofing materials and the like. The finishing agent is applied in a foam composition to a downwardly moving length of textile material immediately prior to the passage of the material through a pair of horizontally disposed pressure rollers. A predetermined quantity of the foam composition is maintained just prior to the pressure rollers in a dam through which the textile material passes. The pressure rollers break the foam and impregnate the finishing agent into the textile which is thereafter dried and/or cured/or fixed.
Claims9
A process for applying a finishing treatment to a textile material which comprises
- forming a stable foam composition which includes said finishing agent therein;
- routing said textile material downwardly in a substantially vertical path through a pair of horizontally disposed pressure rollers;
- maintaining a predetermined amount of said foam composition in a dam disposed along the vertical path of travel of said textile material at a point upstream of said pressure rollers;
- routing said textile material in the proximity of said dam to apply said foam composition to at least one side of said downwardly moving textile material at a point prior to the passage of said textile material through said horizontally disposed pressure rollers;
- and forcing the foam on the surface of the vertically disposed textile material into the material and collapsing the foam by means of said pressure rollers to effect penetration of said foam into said fabric.
