摘要:
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.

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 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.
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.
摘要:
A method for washing out thickening from printed textile material in web form, includes: applying a foam which contains, in its foam-forming liquid, particularly water, only a wetting agent, and optionally a foaming agent, to the printed side of the textile material; working the foam into the textile material; steaming the textile material; applying either foam which contains, in its foam forming liquid, particularly water, only a wetting agent and optionally, a foaming agent, or hot water to the backside of the textile material; and applying suction to the printed side of the textile material.
摘要:
In a fabric treatment apparatus for applying a washing or rinsing liquid to a dyed or printed textile web, the web is transported by a sieve conveyor belt along a horizontal path. Spaced from one another along that horizontal path are several liquid applicators or spray pipes. Associated with each spray pipe is a respect dwell stretch and a suction device, the dwell stretch being located downstream of the respective liquid applicator and upstream of the respective suction device. The dwell stretch includes either two sets of rotatable rollers spaced a distance from one another or a rotatable sieve drum.
摘要:
An apparatus for supplying liquid to an elongated liquid reservoir in a uniform manner over the length of reservoir comprises a trough, extending transversely over the width of a continuous fabric web, into which a liquid is poured from above, and a feed pipe extending longitudinally along the trough. Short, identically formed, curved tubes are uniformly distributed over the length of the feed pipe and arranged to extend transversely therefrom. The liquid is supplied over the length of the liquid reservoir from the short tubes disposed at a plurality of sites along the reservoir. The cross sectional area of the feed pipe may be significantly greater than the total cross sectional of all of the curved tubes to prevent a significant pressure drop.
