PATENT OFFICE.

-V - vBy all devices known so far bleaching (or impregnating, boiling and dyeing) textile material with a circulating liquor has the disadvantage to fight so that the fleet looks for ways in the material and forms channels through which the resistance becomes less than in neighboring parts. As a result, the liquor cycle is uneven and accordingly also the product unevenly. Particularly noticeable unpleasantly this phenomenon occurs in bleaching, and in such a way that certain Place the goods not at all or not sufficiently boiled out, degreased or. be bleached, whereby the finished goods appear inferior, often even worthless.

All suggestions which should bring a remedy in this direction have been found not proven.

The present invention is now a method and the associated device, to receive a commodity treated equally in all parts, and the essence exists of the invention therein, during the work of the circulating fleet a step by step or to give a constantly changing direction, so to be sure, that in different directions one upon the other following periods of time the direction of the fleet as it penetrates through the goods is changed, whereby again and again other parts of the commodity in the direction of the flow of the liquor reach.

Namely, on the one hand, the entry point of the fleet becomes steady or during work changed by leaps and bounds and on the other hand consistent or independent of the The exit point of the fleet was changed, so that the direction of the fleet was also changed from the entry to the exit point changes again and again.

To carry out this method, a device is used in which the liquor through a sieve cover divided into sections (sectors) again and again to others' Places where the material is fed, while (e.g. in the case of boiling kettles) the space under the Sieve bottom is divided into chambers by walls (concentric or axial), which each through a special pipeline (or channels) with a control slide (resp. Faucet or valve), which they continuously or step by step with a pump, an injector or vacuum tank, which connects the cycle of the liquor effect, so that every point within the commodity to be treated repeats and goes through differently directed liquor flows is penetrated and the approximately in the course of the fleet in the one direction formed channels in the subsequent changes of direction relocated and rendered harmless

will. This procedure will be using cold or moderately warm liquid in a short time Time achieves successes that could previously only be achieved through lengthy boiling,

without thereby allowing the formation of channels

The construction of an apparatus suitable for carrying out this process will result from what has been said, and let the following example be the construction of a bleach cooker. (The construction of boilers for impregnation respectively Coloring is essentially the same.)

In the accompanying drawing, FIG. 1 shows a longitudinal section and FIG. 2 shows a cross section along line xx through FIG. 1.

A is the "kettle-shaped" container in which the goods are to be bleached (or impregnated or colored); the boiler is equipped with a sieve base B on which the textile material introduced through the manhole M after the sieve cover D has been lifted is stacked. The space under the sieve bottom is divided into three (or more) sector-shaped chambers k U ₁ k by two (or more) vertical walls w. ₂ divided, each of which is provided with an outlet opening 0 O ₁ O ₂ and pipelines rr _x r, ₂ adjoining this; the strainer cover D is again ν by a number of radially standing walls V ₁ V ₂ ... into a plurality of segment-shaped divisions ₁ Ji J, divided ... and the liquor is fed through a central ,, introduced inside the boiler knee-shaped bent pipe R , which, stored tightly in the boiler socket 5., is set in rotation continuously (or suddenly) by an attached pulley η from a transmission t.

Further in the jacket of the boiler A three (or more) places are covered with sieves i Z ₁ L ₂ and from the outside with hoods /; Time ₁ h. ₂ tightly covered, to which pipelines i ~ ₃ r _i r _{s are} connected.

The repeatedly occurring change of direction of the fleet running through the boiler can be caused by a control mechanism, which is expediently designed in the form of a multi-way valve or rotary valve and z. B. consists of a cock housing H in which a cock plug K rotates; the tap housing H, which is tightly sealed on all sides, is provided on its circumference with as many outlet nozzles lying in a circle as there are pipelines r T ₁ ... branch r ₅ from the boiler; Each of these pipelines opens in this way into the tap housing H, which is connected to a suction and pressure pump P, which sucks the liquor out of the boiler from below and feeds it back to the boiler through the tube R at the top. Cock plug K is drilled (at right angles) and is set _{in rotation by a transmission disk W 1} attached to its spindle ρ , so that the side opening of the cock plug bore is repeatedly connected to another of the pipelines r ... r ₅ in connection, while the lower opening of the cock plug bore always remains in connection with the pump. However, it is also possible to achieve the same effect by using taps or valves in the individual lines, which are opened and closed alternately.

The operation of the device is now easy to understand.

The material to be treated is coated in the boiler between the sieve bottom B and the sieve cover D, the manhole M is closed, the effective fluid (liquor) is supplied through the pipe R and at the same time, the pump P in action, and by means of the transmission disks KM _1, the tube R and the cock plug K is set in constant (or abrupt) rotation, whereby the mutual speeds of rotation of the pipe R and the cock plug K can advantageously be temporarily changed (increased or decreased). By rotating the tube R , the liquor is alternately the successive segment-shaped sections Si ₁ I ₂ J _3. ,,. des, sieve cover supplied and by the rotation of the cock plug K the liquor, one after the other through the pipes r. . . r ₅ , ie sucked off at a different point each time; the direction that the liquor takes through the material is therefore frequently changed with each revolution of the tube jR and the plug K. The lines of communication between the entry and exit of the fleet, which change at every moment, cross in all directions, and this gives the fleet the opportunity to repeatedly penetrate the material in all its parts, and to form paths or canals through which the fleet will operate during the entire duration of the work could flow through unhindered, while it does not penetrate other parts of the material, or penetrates only with difficulty, appears to be impossible.

A method of bleaching (or dyeing) of textile materials in vessels closed on all sides, characterized in that the Fleet to the material to be treated constantly or in jumps to always different Points fed and also constantly or in leaps and bounds at always different ones Places is sucked off, thus by a constant change of direction of the cycle of the fleet all Parts of the goods are treated evenly and the formation of channels or paths through which the liquor could pass without resistance during the whole treatment is prevented
