Abstract:
A process for treatment of cellulosic material, for example, knitted or woven cotton fabric or yarn, comprises treating cellulosic material with a pectinase and a surfactant.
Abstract:
In known pressure impregnating devices, a chamber that becomes continuously narrower in the transport direction is located between a roller surrounded by the web to be impregnated and the inner wall of a trough which contains the impregnating medium. The impregnating medium is supplied to the chamber under high pressure, and that pressure is further increased in the chamber by dynamic effects. The high pressure causes sealing problems at the inlet and outlet slits, as well as at the front sides of the device. Fluffs detached from the paper web and impregnating medium that penetrates between the sliding surfaces may disturb the operation of the device. The invention aims at solving these inconvenients. The new device has seals with alternatively narrow and wide grooves (12, 23, 24), in the manner of labyrinth seals. The grooves (12, 23, 24) are provided with outlets (14, 25, 26) for the impregnating medium that flows through the grooves.
Abstract:
Die Textilbahn (1) wird durch einen relativ engen Schacht geführt, dessen Begrenzungswand wenigstens teilweise durch die Oberfläche von Walzen (2, 3) gebildet wird. In den gekrümmten Abschnitten (6, 6') des Schachtes sind Düsen (7) angeordnet, aus denen ein Behandlungsmittel auf die Textilbahn aufgetragen werden kann. Gerade Abschnitte (8) zwischen den Walzen können sehr kurz gehalten werden. Die Vorrichtung eignet sich insbesondere für die Behandlung von zugempfindlichen Textilbahnen.
Abstract:
Die Behandlung der Materialbahn (2) erfolgt in einem U-förmigen Schacht, bestehend aus zwei Schachtschenkeln (3, 4) und einem Verbindungsbereich (5) zwischen den beiden Schachtschenkeln. Der Schacht ist mit Behandlungsflüssigkeit gefüllt, wobei die Zufuhr neuer Behandlungsflüssigkeit, aber auch die Umwälzung der Behandlungsflüssigkeit in den Schachtschenkeln unterhalb des Flottenniveaus erfolgt. Bei äusserst sparsamem Einsatz von Behandlungsflüssigkeit wird dabei eine besonders intensive Beladung der Materialbahn bewirkt. Ein Aufschäumen der Behandlungsflüssigkeit wird auch bei starker Turbulenz verhindert.
Abstract:
The present invention relates to a permeation system for fabric and a method for manufacturing fabric using the same, and the permeation system for permeating a wetting agent into fabric comprises: a fabric supply part; a permeation part provided with a permeation device and a height adjustment device; a drying part; and a collecting part for winding the fabric, which has passed through the drying part, around a collecting roll, thereby obtaining functional fabric of uniform quality and increasing productivity of the fabric into which the wetting agent is permeated.
Abstract:
The treatment of a material web (2) ensues in a U-shaped shaft comprising two shaft limbs (3, 4) and a connecting area (5) between both the shaft limbs. The shaft is filled with a treatment liquid, the feed of fresh treatment liquid and also the circulation of treatment liquid ensuing beneath the surface of the liquor within the shaft limb. The effect is a particularly intensive charging of the material web, with extremely economic use of treatment liquid. Foaming of the treatment liquid is prevented, also in the case of heavy turbulence.
Abstract:
Improved methods and treating units for the continuous and open width washing of textile products of manufacture, after the printing and/or purging and bleaching thereof, comprising advancing said textile product of manufacture through a treating environment, including a treating bath, on a permeable conveyor and under the control of liquid blades as supplied under recirculating conditions from the bath, with comparatively high flow rates and comparatively low pressures, in such a way that liquid jets provide a dynamic impact and heat entrainment action on the advancing material, material being preferably, while not necessarily, predisposed in laps on permeable conveyor.
Abstract:
Apparatus for treating webs of material with several buoyant rolls which engage the web of material, consist of a closed buoyant body and are arranged in a trough which contains liquid, is open at the top and is at atmospheric pressure, parallel and adjacent to each other horizontally restrained but freely floating in the vertical direction without touching each other. The rolls may be arranged horizontally side by side without forming roll gaps or vertically on top of each other, forming roll gaps with two guide rolls provided above each buoyant roll.
Abstract:
The disclosure relates to a process for continuous wet treatment of textile material in a container holding treatment liquid through which the material is being transported and is being penetrated by treatment liquid in a manner which is essentially vertical to its surface, and to devices for carrying out the process.In a particularly appropriate device, textile material 16 is introduced from the top into treatment liquid 28, then is guided around a minimum of one part (52, 80, 81, 120) which is arranged in the lower region of inner container (30, 85, 87, 119) liquid permeable to a limited degree, along a wall, and is thereby deflected and transported in the direction of the upper edge of inner container (30, 85, 87, 119).
