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. The process of this invention generally leaves the textile material essentially dry to the touch and thus requires less energy consumption in drying and further treatment of the textile.
This application is a continuation-in-part of application Ser. No. 148,226, filed on May 9, 1980, abandoned, which in turn is a continuation-in-part of application Ser. No. 883,241 filed on Mar. 3, 1978, abandoned, which in turn is a continuation-in-part of application Ser. No. 670,528 filed on Mar. 25, 1976, abandoned.
Liquid fabric softening compositions for use in a rinse bath after washing fabrics with a detergent. The softening compositions have a pH of less than about 7 and contain certain specific light-stable dyes at levels which provide a pink color.
A textile treatment process, treatment bath, and treated fabric are disclosed. The process imparts water repellant, stain resistant, and wrinkle-free properties as well as aesthetically pleasing hand properties to a fabric made in whole or in part of fibers having a hydroxyl group, such as cellulosic fibers, though immersion in an aqueous bath and subsequent heating for curing. The aqueous treatment bath contains 8%-14% urea resin, preferably DMDHEU, and 4%-10% of a polytetrafluorethylene, preferably ZONYL.RTM. PTFE.
Liquid fabric softening compositions for use in a rinse bath after washing fabrics with a detergent. The softening compositions contain certain specific oil-soluble light-stable red dyes and pigments as colorants at levels which provide a pink color. The colorants are difficult to incorporate and require better mixing than water-soluble dyes.

Liquid fabric softening compositions for use in a rinse bath after washing fabrics with a detergent. The softening compositions have a pH of from about 2 to about 6 and contain certain specific yellow/blue colorants at levels which provide a yellow color in the composition and when said compositions are diluted in the rinse water of a typical laundry process, they have a pH of more than about 7.5 and a desirable blue color.
