摘要:
A binder applicator for applying binder to a moving substrate includes a distribution pipe extending transverse to the direction of movement of the substrate, with the distribution pipe having a bottom provided with a discharge opening. A distributor channel receives liquid binder from the discharge opening and directs the liquid binder upward. A horizontal reservoir receives the liquid binder material from the distributor channel, and a weir meters the discharge of the binder from the horizontal reservoir to form a thin horizontal flow of liquid binder material. A curved surface receives the thin flow of binder material and gradually changes the flow path to a substantially vertical thin flow of binder material for discharge onto the moving substrate.

An apparatus for applying a treatment fluid, such as dye, onto an advancing web of material has a run-off surface sloping down toward the web that extends above and over the width of the web. The dye flows onto the web from the lower edge of the run-off surface. The dye is applied onto an upper zone of the run-off surface from individual nozzles, which are a constituent part of nozzle combs that are pivotable about a transverse axis between a first position disposed above the run-off surface and a second position over a run-off gutter.

An apparatus for applying a treatment fluid on a web of material includes a run-off surface extending transversely over a web to be treated. The run-off surface slopes down obliquely onto the web and has an upper portion upon which treatment fluid applied thereto flows down over the run-off surface onto the web via the lower edge thereof. A flow homogenizing baffle is provided on the run-off surface. The baffle is formed from closely spaced deflection elements that even out any irregularities that exist in the fluid film flowing over the upper portion of the run-off surface.

A liquid applicator for a wide length of material, operating according to the overflow principle, has a construction which ensures uniform dye application over the operating width. This applicator now makes it possible to effect quick color change, because the capacity of the applicator is smaller than 5 l/m and, by a special arrangement of liquid-distributing chambers in the applicator, a uniform liquid film exhibiting laminar flow is ensured.

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:
Process and apparatus for treating a porous, absorbent material with a foamable chemical composition, in which a liquid chemical composition that is capable of being foamed, or a porous, absorbent material substrate containing such liquid composition, comes in contact with a porous substance through which air or other inert gas is being forced, to produce an aqueous foam which is used to treat the substrate. The invention eliminates the need for expensive foam generating and applying equipment, and makes it possible for presently employed fabric processing equipment to be inexpensively modified to use aqueous foam treatment for dyeing or other applications.

Apparatus for the application of liquids to moving material, such as patterned application of dyes to moving textile material, including a liquid applicator positioned above the material path of travel for continuously discharging liquid in a row of plural streams downwardly onto the material, means for selectively deflecting selected of the continuously flowing streams in accordance with a pattern control device, and collection means for receiving the deflected liquid to prevent its contact with the moving material, and wherein the collection means includes a collection chamber having an opening for receiving deflected liquid, and three collector plates positioned adjacent the lower portion of the liquid-receiving opening to prevent liquid from falling onto the surface of the moving material from the collection means in an unscheduled manner. The primary collector plate being made of very thin metal and being capable of having tension applied to the extremities.

Methods of and apparatus for cold dyeing pile fabrics, particularly carpets, wherein dye liquor is first applied to the pile side of the fabric in an amount between 150% and 300% of the material weight, the dye impregnated fabric then being coiled, under tension, into a roll and the roll allowed to stand, all at room temperature. The magnitude of the tensile force applied to the fabric is greater than about 90% of that required to cause dye liquor to emerge from the roll, but is not more than that which enables 5%, at the most, of the liquor to emerge from the roll.
摘要:
An improved method and apparatus for dyeing a pile fabric web to produce very novel and distinctive multicolored designs is disclosed. In the practice of the invention a plurality of dyes are applied to a moving pile fabric web with each color or dye being applied as separate, individual streams at varying points along a line traverse of the moving web. The apparatus comprises a pair of identical, opposed dye applicators mounted above a moving web with each applicator unit including a dye holding tray; a dye pickup roll mounted within the tray; a doctor blade mounted adjacent the pickup roll for removing a layer of dye from the roll; a plurality of channels mounted on, or formed integral with, the doctor blade and which divide the dye into separate streams or drippings, each of said channels having a discharge zone for discharging the separate dye streams or drippings; plug means for blocking the flow of dye through preselected ones of said channels whereby preselected streams of dye are blocked from the discharge zone; and means mounted immediately above each of said channels for selectively dispersing a further dye or dyes at points adjacent the discharge zones of the channels which are blocked out by the plug means. In this manner, a plurality of dye streams are applied to the moving web at separate points along an area or a line transverse of the moving web. The apparatus further includes interruptor elements mounted below the discharge zone of the channels to interrupt the continuous flow of the separate dye streams or drippings.

An apparatus for the colouration of textile materials with a gaseous stream containing a dyestuff, or dyestuffs, in vapour form, which comprises means for passing a hot stream of inert gas over a dyestuff and means for allowing the resulting stream of gas containing dyestuff vapour to impinge on the textile material, in particular an apparatus comprising a reservoir for containing an inert gas under pressure, said reservoir being connected to a tube fitted with heaters, said tube containing a receptacle for the dyestuff, and the other end of the tube being fitted with a jet from which issues the stream of inert gas containing a dyestuff vapour. The apparatus is preferably used for colouring synthetic textile materials with volatile Disperse Dyestuffs.
