Abstract: The method of dyeing a continuously moving carpet pile fabric with a base color and thereafter applying other color dyes onto the base color and fixing all of the dyes without the use of steam. The dyeing process employs a dye applicator to which a heated dye solution is supplied and this dye is sprayed onto the carpet while at a temperature of approximately 185.degree. F. to 205.degree. F. to provide the base color. The base color dye is applied with a wet pick-up of approximately 200 percent to 300 percent. Thereafter while the carpet is still hot from the wetting by the hot dye, other color dyes at substantially ambient temperatures are independently sprayed onto the carpet at spaced locations while the carpet is still in the temperature range of approximately 165.degree. F. to 175.degree. F. The total amount of additional dye applied subsequent to the base color dye provides a wet pick-up of approximately 120 percent.

Abstract: The method of dyeing a continuously moving carpet pile fabric with a heated base color dye and either thereafter applying other color dyes onto the base color or applying the other color dyes prior to the base color, all of the dyes being fixed by the heat of the base color dye and without the use of steam. The dyeing process employs a dye applicator to which is heated dye solution is supplied and this dye is sprayed onto the carpet while at a temperature of approximately 185.degree. F. to 205.degree. F. to provide the base color. The base color dye is applied with a wet pick-up of approximately 200 percent to 300 percent. The other color dyes, which are pattern colors, at substantially ambient temperatures are independently sprayed onto the carpet at spaced locations either before the heated dye is applied or subsequent to the hot dye while the carpet is still in the temperature range of approximately 165.degree. F. to 175.degree. F.

Abstract: A jet printer for dye printing a moving web of material by application of a selected plurality of streams of liquid dye. A dye supply tube corresponds to each dye stream and is disposed above a respective dye discharge tube which in turn is disposed above the moving web. A deflecting finger corresponding to each supply tube is pivotably mounted in a housing for selective movement into and out of the path of dye flowing from the supply tube. Each finger is carried by a support block which carries a permanent magnet in the form of a small cylindrical member. An electromagnetic coil in a control circuit is mounted with the core of the coil adjacent a peripheral portion of the magnet. Control circuitry selectively controls the polarity of the coil to attract one end of the magnet toward the coil and the other end repelled therefrom, and when the polarity changes the magnet moves in the opposite direction. Movement of the magnet pivots the respective support block and deflecting finger.

Abstract: Methods and apparatus for fixing dye to pile fabrics such as carpet material by employing the electrical conductivity of the wet carpet itself for the purpose of heating the carpet and dye to a temperature sufficient to fix the dye. The present apparatus, in the space of several feet along the length of a continuous carpet treating apparatus, performs the same function as a conventional carpet steamer, which is typically several hundred feet in length. In one specific form, the electric current is passed in a direction through the thickness of the carpet employing a pair of flat plate-like electrodes which contact the front and back surface of the carpet. In another specific form, the electric current is passed through the carpet in a direction generally parallel to a surface of the carpet, e.g. longitudinally, employing electrodes on the back surface of the carpet which do not disturb any pattern which may be printed on the carpet during the dyeing process.

Abstract: A method of carpet treating and apparatus for the dyeing of intricate patterns is provided wherein a plurality of spray nozzles are disposed in a spray line transverse to the direction of movement of a carpet. Each spray nozzle is connected to a mixing chamber where air and treating liquid preferably dye, are applied at selected pressures between 0 and 60 p.s.i. Depending on the relative pressure of the air and liquid dye, the mixture is caused to be either atomized or foamed through the spray nozzles onto the face of a moving carpet web. Each nozzle is connected to its own separate mixing chamber the input of which are controlled through a corresponding control valve which turns on and off the spray nozzle by opening and closing a corresponding gas valve and corresponding dye valve.

Abstract: A method for treating textile materials, such as carpet, employs an applicator station having a number of spray jets for causing a plurality of streams of fluid to be fanned out into a corresponding plurality of fan shape sheets of spray directed to the surface of a roller. The spray jets are used to spray either air, dye or gum. The roller is mounted for rotation in a dye or gum trough and the jets spray air or other fluid to cause a pattern to be formed in the dye or gum film on the roller. The pattern is transferred to the face of the carpet by a doctor blade or, alternately, directly to the carpet face. The trough may be filled with gum in which case the jets spray dye onto the film of gum picked up by the roller. The trough may also be used for dyeing in which case a different color dye is applied by the jets or multiple roll applicator stations may be provided for multi-color and tone effects. Alternately, no trough is used and dye or gum may be applied by the spray jets to the roller.
