摘要:
Apparatus for treating textile webs in a treatment fluid such that the material lingers in the treatment fluid for a period of time, in which a support bottom in the form of a trough extending transverse to the textile web and a swinging or oscillating member, having the same curvature as the trough, freely suspended at an eccentric and rotated about an axis parallel to the trough with the direction of the rotation the same as that of the travel direction of the textile web through the trough, form a channel at the beginning of which the textile web is placed in transversal folds and at the end of which the web is drawn off, all of the channel being situated below the fluid level thereby resulting in an improved rinsing action as the web is moved through the channel with the oscillating member aiding in both the rinsing action and in moving the web of material through the channel.

In dwelling treatment apparatus for a textile web through which the web passes in a folded condition, the apparatus having a J shape with an inclined leg and lower arc, the leg is adapted for controlled inclination with respect to the vertical to control the component of force due to the weight of the folds which acts to move the web through the apparatus.
摘要:
A jig has two winding rolls in two troughs which surround the winding rolls concentrically and contain treatment liquor, and a squeezing device for a web of material passing from the one to the other winding roll arranged between the winding rolls. The squeezing device is arranged high enough that the web of material runs from the squeezing device downward toward both sides. A partition extends upward between the troughs up to the squeezing device.
摘要:
A device for continuously treating a textile fabric web comprises at least one application devices for applying one or more treatment liquors to the fabric web. After applying the liquors, the fabric web exhibits a total moisture content in the range of 100 to 220% of the weight of the dry fabric. The fabric web with the moisture is fed into a tower-like heating zone of an ager, in which the fabric web is guided over a path consisting of a plurality of horizontal loops.

A continuous process for treating a web of material by the wet-in-wet application of two serially arranged treatment baths includes the steps of: applying a first treatment bath to the web; squeezing off excess moisture from the web to a specified moisture content; applying a second treatment bath to the web while it is still wet from the first treatment bath such that the web is in contact with a quantity of the second bath that is no greater than that quantity that can be continually absorbed by the web; replenishing the second treatment bath; and reducing the moisture content of the web to a specified moisture content immediately after application of the second treatment bath.
摘要:
A method and apparatus for the continuous treatment of a textile web is disclosed. The apparatus comprises a foulard in which the textile web is provided with a first treatment bath and squeezed off to a moisture content of 60 to 100%. The web then is conducted to a gore applicator in which the web is provided with a second bath application of 40 to 100%. The second application occurs in an upright vat in which the textile web is always in contact with only a very small quantity of continually replenished treatment bath. The vat is sealed at a bottom gap by two mutually opposing inflatable hoses with one hose disposed on each side of the textile web. The hoses sealingly abut against the web and wipe off treatment bath entrained by the web to a predetermined total moisture content. In the dyeing process, the web subsequently runs into a steam apparatus and then into a washing apparatus.
摘要:
A device for applying a treatment medium, especially in foam form, to a running web of material, especially a rug web, with an application beam extending transversely to the web of material, the application beam having a longitudinal slot, through which the treatment medium emerges onto the web of material. On the side opposite the slot an elastic cushion which presses the web of material against the sliding surface of the application beam is arranged on the back of the web of material. The cushion may be an inflatable elastic hollow body or a foam material cushion.
摘要:
In a device for the storage and reaction treatment of textile material in web form for continuous passage which includes a cylinder, a transporting device for transporting the textile material onto the surface of the cylinder in the circumferential direction thereof, a pleating device for pleating the textile material in several layers with folds parallel to the axis of the cylinder onto the top of the cylinder, a depositing device arranged underneath the cylinder, and a pulling off device for pulling the textile material off at a point following the lower crest of the cylinder in the travel direction, dissolving the folded layers, the velocities of the transporting device and the pleating device and the stroke of the pleating device are controlled such that the folded layers extend at least one-third on both sides of the upper crests of the cylinder and that the length of a folded layer from one fold to another fold is one-quarter to one-half of the cylinder circumference, and that the folded layers cover each other on at least two-thirds of their length.
摘要:
A liquid, foam or paste treatment medium is applied to a textile or similar web as the web is led through a gap in which the web is pressed resiliently against an opposing face in an area extending over the width of the web with non-uniform pressure by, for example, several adjacent cushions that are independently inflatable. The non-uniform pressure serves primarily to achieve uniform treatment, in particular, uniform coloring, despite the non-uniform conditions existing over the web width. The non-uniform pressure may also be used for imprinting patterns on the web.
摘要:
A method and apparatus for applying a pattern to a continuously advancing web with a foam containing treatment medium. The pattern may be generated in the foam prior to or after the foam is transferred to the web. In one embodiment, the pattern is generated using two foam feeding devices arranged to form a patterned layer on a revolving element positioned over the web. The forward velocity of the web and the speed of rotation of the revolving element are controlled to obtain the desired pattern effect on the web.
