No. 729,178 Claims priority, application Germany, May 24, 1967, V 33 8 Inf. C1.
  • the present invention relates to a process and apparatus for the continuous pad dyeing and/ or printing or bleaching of textile lengths of materials, for example knitted tubes. More particularly the present invention is directed to a process and apparatus which uses preparations Iwhich react under the influence of heat, for example dyestuffs which x under the influence of heat.
  • the present invention is particularly suited for the application of the space; dyeing process. However, it also offers substantial advantages for continuous bleaching and/or dyeing processes.
  • space-dyeing is used to define a process in which the yarn is printed with several colors to obtain, after processing, a uniform irregular coloring of the piece goods.
  • Space-dyed yarn is generally used for tufted carpets and also occasionally for woven and knitted fabrics. The advantages of space-dyed yarn are as follows:
  • the yarn can be simultaneously printed with several colors.
  • Leveling agents as they are used when continuously dyeing piece goods, can be dispensed with and, in general, cheaper dyestulfs can be used than in continuous dyeing.
  • Seconds can be effectively processed using this method, that is, it is not necessary that the capacity of dyestuffs absorption be absolutely uniform as is usually required for continuous dyeing.
  • the dyestuff application be as irregular as possible so that after processing there is no patterning in the ready piece.
  • the term patterning designates stripes of one color in the ready fabric and/or the tufted carpet. These stripes have usually marble shapes. If patterning occurs, it is an indication that the color application was not irregular enough ICO and generally that the printed patterns repeat too frequently.
  • the material be guided ⁇ with as little tension as possible through the plant in order to avoid a removal of the texture which, in general is not yet fixed in the yarn. Another requirement is that with multicolor prints, marking off and/o1 smearing of the dyestuffs particles adhering to the conveying elements must be avoided in continuous operation so that the desired multicolor effect is not contaminated.
  • the knit deknit process can be subdivided into the following process stages:
  • An object of the present invention is to avoid the prior art disadvantages in the continuous pad dyeing and/or printing or bleaching of textile lengths of materials.
  • Another object of the present invention is to provide an improved process and apparatus for the continuous pad dyeing and/or printing or bleaching of textile materials wherein bleeding and marking ol of the individual color spots are substantially avoided so that clear contour lines are obtained.
  • a further object of the present invention is to provide an improved process and apparatus for the continuous pad dyeing and/ or printing or bleaching of textile lengths of materials wherein said material is conveyed through the treatment stages in such a manner as to avoid the removal of the texture of the textile material.
  • the textile material which has been printed with preparations is passed into the treatment atmosphere on a conveying element which is gas or steam-permeable and if in the treatment chamber the gaseous or vaporous treatment medium is blown upwards against the textile material and/or penetrates the textile material in an upward direction, so that the textile material simultaneously rests on a steam or gas cushion.
  • proper material shrinkage is ensured without unevenness or unlevelness and smearing caused by tensile stresses and/or by the movement of the material on the conveying element.
  • textile materials with a high degree of shrinkage for example texturized polyamide yarns are processed
  • the textile material can be stacked up in folds without being damaged in any way.
  • a unit for the application of the preparations for example a padder and/ or a printing unit,
  • a heat-treatment unit for example a steaming unit, with material penetration
  • a dryer preferably a sieve drum dryer with a folding or winding unit and possibly a material accumulator between the dryer and the folding or winding unit.
  • the device suggested above may also have the heat-treatment unit as the last unit if the heat-treatment unit is designed as a hot air setting chamber, that is if the process used is for example a Thermosol-process. If the available floor space is limited, it is suggested to subdivide the plant behind the heat-treatment unit and to set up separately the washing and rinsing device with a subsequent dryer system. However, in this case extra costs are involved because at least one further operator is required.
  • a winch and/or a slot roller which is arranged in such a way that the textile material is removed directly from the nip without resting against one of the two rollers.
  • the conveying element between the application unit and the heat-treatment unit should always be dry when taking over the material, and smearing of the dyestuff applied to the material must be avoided.
  • the textile material that is the knitted tube, for example texturized polyamide yarn is overfed onto the sectional lattice belt in an amount up to about 30% in order to ensure full shrinkage of the textile material during fixing
  • the textile material hangs in small loops between the individual support edges of the belt. It is of importance that the loops are not too large in order to avoid a removal of the texture by the wet textile material as well as sagging of the print color and thus a varying dyestulf fixation.
  • Tests have shown that the distance between the individual supporting slats should not be larger than mm. Preferably, the distance between the individual supporting slats is about 50 to 100 mm.
  • sectional lattice belt of T- sectional slats which are laterally mounted to chains or elastic belts so that the T-sectional slats can be exchanged. This is possible if the slats for example are screwed to the belts or chains.
  • a blower preferably a cross-current blower which blows the vaporous or gaseous treatment medium in an upward direction through the conveying element which extends into the treatment chamber.
  • the cushion provided by the current of the treatment medium carries the textile material during the heating-up process, during which period liber setting and liber shrinkage occur.
  • the gas or steam cushion ensures an absolute tensionless treatment of the material being treated.
  • the treatment medium produces a lifting effect on the material disposed on the sectional lattice belt which extends into the treatment chamber and also on the textile material as it is deposited on the conveying element, for example a wire mesh belt, of the heat-treatment unit.
  • the whole material weight does not act as tensile stress on the material but only the difference between the weight of the material and the lift produced by the blower acting on the material.
  • the height of the fall between the sectional lattice belt and the conveying element of the heat-treatment unit be adjusted and adapted with respect to the paricular material. This can be effectively achieved by supporting the inner deilector elements of the conveying element in such a way that they can be adjusted in height.
  • the sectional lattice belt and the conveying element of the heat-setting unit for example the steamer, must be dry when the wet textile material is deposited thereon in order to avoid marking off. This can be ensured, for example, by correlating to each of these elements one drying blower. Also a common drying unit may be provided for these elements. Furthermore, the conveying element of the heat-treatment unit should be provided with a continuously operating Washing unit.
  • the textile material is overfed and/or folded onto the conveyor belt of the steamer.
  • Tests have shown that the material length can be overfed by about l5 to 30 times.
  • the folds in the textile material are removed and the material length, that is the knitted tube, is passed through the suction drum wash bowls and the sieve drum dryer.
  • a control assembly which comprises three drive groups which operate independently of each other. These drive groups include:
  • An inlet drive which comprises an individual drive for each knitted tube and/or for each material length with one inlet element each, for example a pair of feed rolls, whereby the scanning device for each material length is arranged between the padder and the printing unit in order to ensure a uniform and tensionless material feed to the printing unit.
  • the small speed differences between the individual feed rollers can be compensated for by the material quantity in the preceding material accumulator, so that the material feeding unit may generally be equipped with one common drive.
  • This drive is controlled by a scanning device behind the heat-treatment unit.
  • the scanning device behind the heat-treatment unit is designed as a swiveling trough into which the textile material drops into folds.
  • the swivel position of the trough is determined by the quantity of material in the trough, and the swivel motion of the trough is translated to a potentiometer which controls the drive.
  • the afore-described plant is also well suited for bleaching and/'or for continuous dyeing, especially for the continuous dyeing of tricot.
  • the printing unit in this case can be disposed of or bypassed.
  • FIG. la and 1b are longitudinal sections of the apparatus according to the present invention.
  • the apparatus of the present invention comprises textile material 1 to be processed being presented, for example, as a tube in a woundup condition.
  • a material feed 2 is preferably provided with an infinitely variable drive 3.
  • the textile material 1 is conveyed into a trough-shaped material accumulator 5 where a certain quantity of the textile material is deposited in an overfed, folded condition, and from where it is drawn olf by means of a pair of rollers 6 before it is passed on to a padder 7.
  • the padder serves for applying the primary color to the material. If white is chosen as the primary color, the padder can be bypassed.
  • the material length forms a loop 10 which is scanned either by a light barrier or, as in the case of the embodiment of the invention shown by means of a scanner roller 11. With this loop the drive for the pair of rollers 6 is controlled. If several material lengths are arranged side by side, each loop is scanned individually and each pair of rollers 6 is controlled separately. In this way it is possible to feed the individual material lengths to the printing unit 8 with the same constant tension which should be as low as possible. It is desirable to attempt to achieve a tensionless feeding.
  • a winch 12 is provided.
  • the support edges of individual slats 13 are Teflon coated or the slats can be made of Teon.
  • the winch is provided in order to draw the textile material 1 out of the nip of the pressure rollers without the textile material resting against one of the pressure rollers. Contact with the pressure rollers results in contamination and a varying dyestuff application.
  • the conveying element 14 consits of a T-sectional lattice belt, the individual T-sections being screwed to lateral chains.
  • Teflon slats are fastened which form the proper support edge.
  • Teflon slats the support side of the T-section may instead be coated with Teflon.
  • a conveyor belt steamer 15 is a particularly important component of the plant as shown.
  • the steamer is provided with an endless wire mesh belt 16 which extends out of the treatment chamber 17 at its discharge end and its inlet end and which is returned from the discharge end to the inlet end beneath the treatment chamber.
  • the treatment chamber is provided with a prechamber 18 subjected to a suction draft at the inlet end thereof and the steam-air mixture forming in the prechamber is drawn off.
  • the wire mesh belt 16 as well as the conveying element 14 are passed through the prechamber 18.
  • a cross-current blower 19 is provided beneath the Wire mesh belt 16 for circulating the steam.
  • the cross-current blower blows the steam upwards through the wire mesh belt and the conveying element 14 as well as through the textile material 1 resting on the belts.
  • the capacity of the blower is adjusted in such a way that the textile material rests only to a slight degree on the conveying element 14 and mainly on a steam cushion.
  • the textile material 1 is thereby substantially penetrated by the steam, heated-up in a shock like manner and fixed during this treatment.
  • the material which is overfed to the conveying element so that small loops are formed may shrink tensionless.
  • the textile material 1 is deposited on the wire mesh belt 16 in folds whereby the textile material is generally overfed about 15 to 30 times.
  • a water seal 2() is provided with an immersion roller 21.
  • a continuously operating device 22 for the wire mesh belt 16 is provided outside the treatment chamber 17.
  • a drying device (not shown) can be correlated to the washing device.
  • the folded textile material is then passed into a trough 23 which is swivel mounted and which actuates a potentiometer and controls the speed of the subsequent washing machine 24 and the sieve drum dryer 25.
  • the washing machine 24 is provided with treatment bowls containing sieve drums 26 subjected to a suction draft and with squeezers 27.
  • the last bowl serves for applying a finishing agent.
  • an immersion roller 28 is provided instead of a sieve drum 26.
  • the sieve drum dryer is provided in a well known way with sieve drums 29 subjected to a suction draft over which the textile material is alternately passed and with a chute 30 at the discharge end which is longer than the chutes of the well known dryers and which is designed as a trough.
  • a folding frame 31 is arranged by means of which the textile material 1 is folded into wagons 32.
  • An apparatus for the continuous treatment of textile materials which comprises, in combination, impregnating means, means for feeding the material to be treated to the impregnating means, a treatment chamber disposed behind the impregnating means and containing an endless conveying means, a lblower means disposed in the inlet portion of the treatment chamber below the conveying means, a conveying element provided between the impregnating means and the treatment chamber and extending into said treatment chamber above the conveying means disposed therein and outlet means for removing the material from the treatment chamber.
  • the conveying element comprises a T-sectional lattice belt, the individual T-sections being secured to lateral chains.
  • the conveying means is an endless wire mesh belt which extends out of the treatment chamber at its discharge end and at its inlet end.
  • washing means and drying means are disposed behind the treatment chamber.
