摘要:
A continuous dyeing plant for a warp thread including a plurality of dyeing/squeezing groups arranged in line, each of which is provided with a respective impregnation or dyeing tank in which the warp thread is immersed, and an oxidation apparatus that has a plurality of upper and lower return rollers, configured to arrange the warp thread on a plurality of vertical planes parallel to each other, and a support frame having at least one upper strut and at least one lower strut, where a plurality of upper return rollers are mounted on the upper struts, such that at least one part of the lower return rollers is rotatably mounted on at least one respective support device that is movable in the vertical direction between a first operating position, in which the movable support device is placed close to the lower struts to keep the lower return rollers at a maximum predefined distance from the corresponding upper return rollers, and a second operating position, in which the movable support device is placed close to the upper struts to keep the lower return rollers at a minimum predefined distance from the corresponding upper return rollers.

Method for dyeing and simultaneously finishing textile material (14) with an ammonia solution (13) containing dyes dissolved therein. The method comprises the following steps: - preparing the ammonia solution (13) containing the dyes and sending this ammonia solution to a machine (11) for processing the textile material (14); - adjusting the percentage of water present in the textile material (14) before said textile material (14) enters into the processing machine (11) so that the overall percentage of water contained in the ammonia solution (13) and the percentage of water present in the textile fibers is at maximum 20% with respect to the total weight of the solution; - entry of the textile material (14) into the processing machine (11) through safety seals (15); - impregnating the textile material (14) with the ammonia solution (13) for at least a few seconds, the textile material (14) being kept mechanically constrained between at least an entrance tensioner element (19) and an exit tensioner element (23); - squeezing out the excess ammonia from the textile material (14), still kept mechanically constrained, in order to obtain an adjustable pick-up of about 80 - 100% with respect to the dry weight of the textile material (14); - evaporation of the ammonia from the textile material (14) inside the processing machine (11); - exit of the textile material (14), dyed and dried, from the processing machine (11) through safety seals (115).

A warp sizing machine (1) includes a sizing unit (2) for sizing a warp sheet (4) and a cylinder drying unit (3) placed above the sizing unit (2), the warp sheet (4) sized by the sizing unit (2) being divided into two separate warp sheets (4a and 4b) and the two warp sheets (4a and 4b) being guided to respective drying cylinders (31 and 32) included in the cylinder drying unit (3). Two rods (15 and 16) corresponding to the two warp sheets (4a and 4b) are provided in a space between the two warp sheets (4a and 4b) moving from the sizing unit (2) to the respective drying cylinders (31 and 32), the rods (15 and 16) rotating at peripheral speeds lower than the moving speed of the warp sheets (4a and 4b) and being in contact only with the respective warp sheets (4a and 4b).
摘要:
Bei den bekannten Verfahren zum Färben von Textilien, wie insbesondere dem Indigio- Färben, wird Sauerstoff in das Färbebad eingeschleppt. Dieser stört die Farbaufnahme der Textilien und muss daher mit Hilfe von Reduktionsmitteln im Färbebad entfernt werden. Dies hat einen hohen Chemikalienverbrauch verbunden mit entsprechenden Kosten zur Folge. Daher soll das neue Verfahren eine Einsparung bei den eingesetzten Chemikalien erzielen. Dies wird dadurch erreicht, dass der Sauerstoff unmittelbar vor jedem Klotzen aus den Textilien (4) verdrängt wird, wobei ein Wiedereindringen von Sauerstoff in die Textilien (4) jeweils vor dem Vergrünen verhindert wird.
摘要:
A warp sizing method performs pretreatment to adhere the pretreatment liquid (36) to a plurality of warps (12) arranged in a sheet-like form and squeeze, and divides the pretreated plural warps (12) into a plurality of warp groups (38, 40) to adhere a sizing liquid (42) to each of the divided warp groups (38, 40). A dividing treatment includes bringing the warps (12) of the warp group (38, 40) to be divided into contact with a guide roller (80, 82) of each warp group (38, 40). A pretreatment liquid (36) contains a sizing liquid (42) having the same or less size concentration as or than that of the sizing liquid (42) to be used in the sizing treatment or water.

A slasher (1) has a sizing tank (4) provided with a movable weir (18). The level of the movable weir (18) is lowered temporarily below a predetermined level of a sizing solution (3) contained in the sizing tank (4) while the slasher (1) is in a steady-state operation to let scum including bubbles (25a) and floating matters (25b) floating on the surface of the sizing solution (3) overflow the movable weir (18) so that the scum is removed from the sizing tank (4) while the slasher (1) is in the steady-state operation.
摘要:
A covering for soft furnishing is impregnated with an insecticide, such as permethrin. The concentration of permethrin is sufficient to kill house dust mites and deter larger insects such as fleas and ticks. The insecticide is released from the covering over an operational period so as to encourage the absorption of the insecticide into surrounding soft furnishings. The covering is manufactured from machined fabric, such as knitted voile, having interstices sufficiently small to reduce the rate of insecticide release over the operational period.
摘要:
Method and device for the continuous finishing of fabrics (11) or knitwear in ammonia, comprising at least a step of impregnating the fabric (11) in liquid ammonia and at least a subsequent step of heating/drying the fabric (11), wherein, before said impregnation with liquid ammonia, the fabric is subjected to at least a treatment of complete deaeration/de-gassing performed in an environment (12) substantially closed and kept in conditions of great depression with respect to atmospheric pressure.
