Abstract: A method of continuous changing dye-color in spray dyeing for a long tape, which is fed by guides continuously. According to a preferred embodiment, one dye-solution is sprayed for the tape from at least one dyeing-nozzle connected to one feeding line, which is either of a pair of feeding lines and which feeds selectively the one dye-solution or one cleaning-solution. When the tape is fed with a predetermined length, the spraying of the one dye-solution is stopped. Then, the one dyeing-nozzle is exchanged with at least one other dyeing-nozzle by turning the one dyeing-nozzle away from the tape and turning the other dyeing-nozzle to the tape for spraying another dye-solution. While the other dye-solution is sprayed, the one dyeing-nozzle, which was used for spraying for a proceeding sprayed portion of the tape, and the one feeding line, to which the one dyeing-nozzle is connected, are cleaned with the one cleaning-solution to prepare for spraying a new dye-solution.

Abstract: A method and apparatus is provided for controlling the distribution of color on a web of textile material in a textile dyeing process. The apparatus includes a color sensor for sensing a selected color characteristic of the textile web, such as, for example, the distribution of color, at a sensing location downstream of a nip device of a textile padding machine. The nip device removes excess dye liquor from the textile web to dispose the textile web at an initial moisture content as it exits the textile padding machine. The amount of the dye liquor removal through the nip operation is controlled in response to the color characteristic sensed by the color sensor so that the textile web is disposed at an initial moisture content upon exiting the textile padding machine which facilitates a desired color distribution when the textile web is subsequently dried.

Abstract: A washing machine uses a turbidimeter to measure turbidity of cleaning water for controlling the duration of its washing and cleaning cycles. Quality of this control is improved by taking measurements when the water flow is weak so that the effects of foams are negligible and waiting until turbidity drops at the beginning of the cycle to detect the initial value used in subsequent steps. Sensitivity of the turbidimeter is automatically adjusted for accuracy when the operation is temporarily stopped and restarted during a cycle.

Abstract: A batch dyeing machine 10 has separate imperforate compartments A and B for facilitating washing of a length of fabric as it is transported from one compartment to the other.

Abstract: A process for the wet treatment of textile materials having capillary-active properties. The textile material, for example, in the form of yarn bobbins, is placed into a treatment vessel with a heated liquid containing chemicals. A negative pressure is generated in the treatment vessel until the liquid boils viborously. The negative pressure is created by means of a vacuum pump connected to the treatment vessel through an intermediate vessel, a liquid separator, pipelines and valves. Simultaneously, a gas, for example, nitrogen, air or oxygen is conducted through a valve into the liquid, so that the entire liquid volume is transformed into a froth having fine pores. The vacuum treatment step is followed by an intermediate treatment step during which the gas valve is closed and the liquid is circulated by means of a circulating pump. The liquid is thus reheated and the vacuum reestablished.

Abstract: The area which is to be cleaned is intially subjected to a pulsating jet of a liquid which penetrates through the area and which liquid contains a cleaning agent. Thereafter the area is rinsed by a pulsating jet of water which also penetrates through the area. Accordingly, the dirt gets dissolved and a mechanical working of the respective area is achieved simultaneously with a rinsing away of the dirt. Immediately thereafter the now wet area is penetrated by a hot pressurized air jet such to achieve a driving away of the dampness and accordingly a complete drying. If necessary, above sequence is repeated. Due to the speedy drying a forming of rings at the cleaned area is prevented and it is immediately possible to see if a visually complete cleaning has been achieved.
