Abstract: Polyaramid fiber is swollen, such as by exposing it to a solvent, and while swollen a substance, such as amine or substituted amine, capable of forming an ionic bond with an acid or anionic dye, is introduced into the fiber, after which the fiber is shrunk, such as by drying, to incorporate the substance into it. Thereafter, the fiber can be dyed or printed with an anionic dye. A solution of the solvent and substance may be prepared, and the fiber contacted with the solution.

Abstract: A method of dyeing a tufted pile carpet on location. The method comprises the steps of spraying a dye liquor onto the pile of the carpet, spraying a sealer onto the pile of the carpet to fix the dye therein and drying the carpet.

Abstract: A novel, durable thermosetting acrylic automotive finish and method for manufacturing same is described which is manufactured from a predispersed, substantially dry composition. The resultant thermosetting acrylic finish has a higher pigment loading at a sprayable viscosity, thereby reducing the number of applications necessary to produce an acceptable automotive finish. In tests conducted by applicants, the described thermosetting acrylic automotive finish exhibits acceptable durability when exposed to solar radiation for extended periods of time.

Abstract: A combination of an aryl sulfonamide-formaldehyde resin and film forming material, such as cellulose acetate butyrate, which may further include a surfactant, such as a non-ionic surfactant including, for example, an alkylarylpolyether, comprises a "universal" dispersant for resin additives, such as pigment materials. This composition generally includes 40-90 weight % of any of various types of additives, including pigments. The dispersant generally comprises from 30-80 weight % film former or binder, which may consist of cellulose acetate butyrate or a solid plasticizer, such as camphor, sucrose benzoate and dicyclohexylphthalate, and from 20-70 weight % of the aryl sulfonamide-formaldehyde resin. Apart from pigments, the additives may consist of fillers, extenders, etc., including, for example, calcium carbonate, antimony oxide and magnesium silicate.
