Drum machine © for the treatment of textiles and a method of shrinking these fabrics using this drum machine

In order to prevent the so-called shrinking and shrinkage of fabrics during use ^ are known, these textiles _t Zo Ba woven or knitted fabric "with the equipment a process subject to ^ the case of textiles consisting of natural fibers, usually as shrinkage and synthetic in usually referred to as heat setting _o (see Bernat, Appretur der Textilien, Springer 196o _p page 170 to page 182 or, page 195 to 202)

In all these methods is continuous Vorgängeρ the aind economically feasible only _D when the length of textiles relatively large or practically endless isto

In contrast, the invention has set itself the task of making the finishing process of shrinking or shrinking economically feasible for cases involving relatively short pieces of textiles or finished items of clothing ₀

The invention consists in the use of Troraraelmasciilnen with drums circulating in a closed space for shrinking loosely filled textiles of limited size to a certain residual shrinkage value. commodity is the value so low that the use of _D Textile is not impaired "

The invention also consists in two traversed the ~ application are _p the first of which refers to the krumpffreie equipment of from natuer "borrowed fibers existing textiles under Ver performed this drum machines and consists ₉ that dieae textiles in the drum alternating and dosed humidification * = »And subjected to drying processeso

The other method is based on the heat setting of synthetic textiles and is a drum drier _ö that dry air is fed "whose temperature is above 180 ° C"

Thanks to the loose filling of the goods into the drum it "the dry air and the moisture-rich goods equal moderately in finely divided ₀ The shrinking of textiles *" the hestehen from natural fibers are _ß the do 'wobbled combination durdh the mechanical action of Maschin "and the Qunil effect resulting from the moistening. The dosing of the mechanical effect of the machine can be varied by the speed of rotation of the drum. the run is done in both directions. The temperature is generated in a known manner by a heating register and the water or steam quantity is controlled by a valve _{or similar}

These and other features and advantages of the invention give you the following information play and the attached drawings »-

Figures J and 4 show how synthetic wares are fixed in a drum ",

In the housing I ₈ , FIGS. 1 and 2, a drum 2 is rotatably arranged on rollers 3 in a known manner. By means of a drive k , the direction and speed of the drum rotation can be controlled. A heating register 5 takes care of the supply of Heiesluft, DL® dureh a fan 6 drawn through the drum and "discharged It can also be a Uralauf the air may be provided" An appropriate lugs of the drum _ρ in · "game as at 7 and 8" are provided spray nozzles for steam or water _s their arrangement are in each case made so should, that a uniform wetting of the goods is ensured '

Dureh attempts is the usefulness of the invention, for "Bo following cases confirmed wordene After dyeing _D dewatering and teasing 70m Baurawol! Loosely knitted fabrics are placed in a drum then ρ the material is dried $. so that a certain condition is assumed _o In the case of a cotton knitted fabric of medium quality, superheated steam (approx. 120 ° C) is now sprayed for a period of five minutes, followed by another drying process, the duration of which may have to be determined by experiment process (objections and drying) = holt.j again so würds at the given material is an R * etkrumpfwert of £ 2 fi reached when erfolgteο mehrfach® a reversed direction of rotation of the drum during the humidification

The optimal process for the respective goods is expediently determined by inserting a test piece into the drum. Over time, empirical values result in ₀

dl can be applied to similar materials _o

In the case of knitted or knitted whole goods, their particular sensitivity must be taken into account »The shrinking process always requires oil with full * Formation of a more or less strong fungus ο This felt is practically invisible with less shrinkage and such fabrics (jersey) are used for the manufacture of garments "to such a substance of about 70 m length shrinking lu about 12>, the dry product is sprayed about five minutes and ansehlieesend again dried If this process is repeated, the result is a shrinkage of about ₀ 15 fe this is the entanglement of the Visible surface If the process is repeated several times, the end product is a fungus «■

How can you see from Figures 1 and 2? are thus provided at the positions 7 and 8β approximately in the imaginary center axis of the drum »SprühdUsen, the moisture or vapor in the direction of the parts in the barrel" the _e contains material to be treated Spray _o Instead of the nozzle assembly at this point, the nozzles 9 also be arranged on a line 10 _p which is fed from the Helz register _o This arrangement is particularly recommended then? if the heating coil is heated with steam ”.

In Figures 3 and 4 there is no spraying with steam or water; it is rather the synthetic material to be fixed, "that with HxIfe the heat, loosely into the drum and the latter replied in turn by the heating coil 15, the ^ nrrSuir> ilm \! influence of Ansaugventi" lators l6 is incoming air to a temperature above 180 ° C and thus 12 pulls in the direction of the arrow on the drum. The heating control can be operated electrically or with steam.
