  • Process of treating fabrics with foam
    Patent number: 4562097
    Abstract: A continuous process for the application of a textile treating composition in the form of a froth or foam to a substrate such as textiles. The process enables the application in a uniform manner of any foamable functional composition that can be used in the treatment of a textile fabric to improve its properties. In the process of foamed functional treating composition is continuously conveyed to the applicator nozzle, the substrate is continuously passed across and in contact with the applicator nozzle so as to simultaneously contact said substrate with the foamed composition and the applicator nozzle at a rate such that a predetermined controlled amount of the foamed functional treating composition is uniformly applied to the surface of the substrate and the foam immediately breaks on contact with the substrate and is readily absorbed.
