Process for printing fabrics with dyes soluble in spirit of turpentine (rosin) on water

摘要

Process in which a container of a certain length rests on supports which have a lifting and lowering device for placing the container at the desired height and the container contains the pure or thickened water in which we pour the liquid composed of the dye soluble in spirit of turpentine, which is insoluble in water, which guarantees us the hydrophilic nature of the dyes so that a piece of material of a length slightly less than that of the container is centred in the machine by means of the rollers and when it is centred the container is raised by means of the supports with lifting devices until the liquid in the container, which in its upper part is composed of dye dissolved in spirit of turpentine, impregnates the fabric to be printed and when this has been done the supports are lowered and the rollers rotated in order, once again, to centre a new piece of fabric. The printed, wet fabric is carried by the same machine to a suction (skimming) device which removes (wrings) the water from it and goes on to a drying tunnel and, once dry, is washed with conventional detergents normally used in the textile industry in order to emulsify the spirit of turpentine and to subsequently remove it by means of rinsing.
