Description

Textile treatment machine and process for drying textile structures

The invention relates to a textile treatment machine, in particular for the continuous treatment of textile structures in the form of linear or flat textile structures, comprising at least one drying device for drying the textile structure with at least one contact drying device and / or an impingement drying device.

The invention further relates to a method for drying textile structures.

In the production of textile structures and / or in the refinement, different methods are used in which they are wetted or impregnated with fluids and then exposed to a heat treatment for the purpose of drying and fixing. Alois Kießling, Max Matthes: "Textile Specialist Dictionary", specialist publisher Schiele & Schön GmbH, 1992 describes the finishing for the treatment of line-shaped textile structures in the form of warp threads prior to further processing into planar structures by weaving or knitting as a preparation process in which the textile structure This process is followed by finishing with roller dryers or hot air Drying of textile linear structures by themselves is known from a variety of different processes, including contact drying as well as In general, a main drying process step follows a pre-drying step.

From the document DE 1 914 231 A, a drum dryer for linear textile structures in the form of warp threads is known, to which a device for predrying with a discharge line directed over the entire width of the chain is known. Slot and a suction port arranged opposite is connected upstream. In this case, a perpendicular to the line-shaped textile structures from the outlet slit blown hot air stream is discharged after flowing through the chain through the intake slot. A disadvantage of this known predrying is that only a small amount of water can be evaporated due to the short residence time.

EP 0 237 033 B1 discloses a device for sizing and drying of warp threads, in which the threads coming from a plurality of warp beams are combined and sized and then vertically split, pre-dried in a pre-drying section with hot air, re-combined, finally dried in a final drying section and on a Kettbaum be wound up. The pre-drying section is formed by a drying chamber, through which the sized linear textile structures are passed individually and separated from one another and exposed to hot air. The final drying section is formed by a cylinder dryer.

From CH 363 958 A a device for the treatment of linear textile structures, in particular yarn sheets is known, in which they are guided plan-shaped through a treatment channel and acted upon by a gas or vapor-like treatment medium.

In contrast, US Pat. No. 4,025,993 describes a device for finishing and then drying a group of threads, in which the drying takes place in a contact dryer.

Document DE10100330 B4 discloses a method in which line-shaped textile structures are first guided in the thread running direction via a contact dryer and subsequently a convection dryer. In the aforementioned systems, the finished linear textile structures, in particular threads often still have a relatively large hairiness, which can lead to yarn breakage. Drying in several successively connected different drying steps is complex and space intensive. The described embodiments are also constructive and relatively expensive in terms of the required control. The drying device itself requires a lot of space and the energy balance is relatively unsatisfactory.

The invention is therefore the object of a textile treatment machine with a drying device for the continuous treatment of textile structures in the form of linear or planar textile structures such that with this an energy-efficient drying of textile structures with relatively little design effort free from a negative effect on the properties Such dried textile structures can be realized. Furthermore, the drying device itself should be designed to save space and be given a simple way to set a drying profile.

The solution according to the invention is characterized by the features of claims 1 and 14. Advantageous embodiments are given in the subclaims.

A textile treatment machine, in particular for the continuous treatment of textile structures in the form of linear or flat textile structures, comprising at least one drying device for drying the textile structure with at least one contact drying device and / or an impingement drying device, is inventively characterized in that the drying device at least one rotatable heatable Cylinder having a textile structure directly contacting surface and a hood associated therewith, which is designed and arranged to be suitable to blow a dry medium on the textile structure, wherein the at least one hood the at least one cylinder in the circumferential direction at a distance wraps around the surface to form a drying section. A textile structure according to the invention is understood to mean a flexible material which consists of a composite of fibers. This can be in different forms, in particular as a line-shaped textile structure or planar textile structure.

Under line-shaped textile structures filaments, yarns, threads or other such structures of one or more fibers are understood. This is usually an intermediate or intermediate product which can be further processed into flat textile structures.

Flat textile structures, also called textile surfaces, may be in the form of woven, knitted or crocheted fabrics. Woven fabrics are textile fabrics made of at least two thread systems crossed at almost right angles to one another, usually warp and weft threads. Knitted fabrics are fabricated structures made by stitching industrially. Knitted fabrics are textile structures that are formed when making stitches by means of a thread and two or more needles.

With regard to the individual definitions of the different terms, reference is made to DIN 60000, the disclosure content of which is fully included for this term. Textile structures are made of cotton, cotton blends with synthetic fibers, plastic, glass fibers or carbon fibers. As plastics find all sorts of plastics, such as polyamides application.

The solution according to the invention offers the advantage of a combination of a contact drying and a so-called impingement drying, ie non-contact drying, simultaneously in one and the same drying section of a device by the combination of a heatable, in particular steam-heated cylinder with a Impallströmtrocknung in the form of a hood. Due to a relatively large wrap angle of the hood with the cylinder, the drying section designed very long. By contact drying a ironing effect is achieved on the textile structure, which serves to reduce the hairiness. Furthermore, this allows the simultaneous convection drying over prior art designs with lower temperatures. By simultaneous combination of contact and Konvektionstrocknung in a drying section through the cylinder / hood assembly creates a mutual support of the respective drying processes. The drying can be realized with a high drying rate in the smallest possible space, whereby a particularly energy-efficient drying process is created.

To realize particularly high drying rates, the hood wraps around the at least one cylinder at an angle of at least 180 °, preferably> 220 °, particularly preferably> 265 °. By means of the wrapping angle selected according to the invention, a desired drying rate of the textile structure can be easily adjusted by means of a small guide path. The combined arrangement of contact and impingement drying in the same guide section is characterized by a structurally particularly simple construction and space-saving design.

For realizing such a high drying capacity, the hood preferably has a continuous inner casing, in particular perforated sheet inner casing, which faces the surface of the cylinder and has a perforation. The hood with discharge openings supporting inner shell can be procedurally simple and inexpensive to manufacture, in which case more complex arrangements and designs of the exhaust openings can be realized with little effort.

In an advantageous further development, a desired or predefined desired drying profile within the drying section in Implementation direction along the guide path and / or transversely to this be determined by the arrangement, geometry and / or interpretation of the perforation of the inner shell of the hood. In this case, for example, the size of the exhaust openings and / or their distance from each other in the directions mentioned vary.

According to a particularly advantageous embodiment, the formation of the exhaust openings via perforations in the inner jacket also allows an easily realizable possibility for active adjustment of a drying profile in different directions, for example via sliding plates, depending on the position relative to the inner shell enlarge or reduce the exhaust openings.

To ensure optimum operation, the distance of the inner shell from the surface of the cylinder in the wrapping region is preferably in the range of 15 mm to 25 mm inclusive, particularly preferably 20 mm.

To increase the functional concentration and to realize particularly space-saving arrangements wraps the hood in the guide direction of the textile structure at least two or more cylinders. This solution also offers the advantage of easier connection to a common dry medium supply system and exhaust air extraction system. As over the hood to be discharged dry medium is air or drying gas use. The hood is for this purpose one or a plurality of hoods together is assigned a dry medium supply system, comprising at least one supply line which can be coupled to a dry medium source, in which preferably a heating device or at least one heat exchanger is arranged. The one hood or a plurality of hoods in common is also an exhaust air extraction system, for example, a suction system for coupling with the environment or an exhaust air recycling Device assigned. The integration of a heat exchanger in the supply line offers the advantage of a possible thermo-technical coupling with the exhaust air extraction system or another system and thus a particularly energy-efficient operation of the hood.

In a particularly advantageous embodiment, the individual dry medium supply system with the exhaust air extraction system can be coupled to form a circuit, wherein optionally means for at least partial or complete decoupling of the dry medium source and / or the environment or an exhaust air utilization device of this are provided. As a result, the drying device can also be operated as a closed system.

The hood and the dry medium supply system associated therewith are preferably designed such that they can be operated with a drying medium at temperatures in the range of in each case including 100 ° C to 200 ° C, preferably in each case including 150 ° C to 200 ° C. The hood can thereby be operated energy-efficiently. Chains or fabrics have different basis weights and thus water contents. This is influenced, for example, with low water evaporation at low temperature of the supply air or smaller amount of air or dry gas. This brings savings in primary energy consumption. In addition, the radiation is reduced in the room, so is given by flexible driving a significant increase in cost-effectiveness. In an advantageous embodiment, the heatable cylinder has a diameter in the range of 0.8 m to 2.5 m, more preferably 1 m to 2 m. This is further heated with steam and constructed and designed so that the steam acting on it can be applied with a pressure in the range of 3.5 bar to 5 bar. The machine parameters of the cylinders are thus much smaller than those chosen over the embodiments of the prior art. This allows a simpler construction of these over a portion of the outer circumference entwined and dry medium The perforated inner shell can be better modified in terms of distribution and extraction and the proportion of air guide, distribution and intake elements can be significantly reduced.

For the pretreatment of textile structures, in particular line-shaped textile structures in the form of chains or other threads for a downstream processing process, for example weaving, the textile treatment machine has a sizing device upstream of the drying device. This is a treatment device by means of which a treatment liquid, for example an impregnating liquid, is used up on the line-shaped textile structures by spraying or dipping before further processing in order to achieve certain predefined properties of these. The textile treatment machine according to the invention is modified according to a first embodiment in a particularly advantageous manner for the treatment of linear textile structures by finishing with subsequent drying.

In order to release the sizing agent from the flat textile structure then present after a successful processing, for example weaving, the textile treatment machine according to the invention for treating flat textile structures is modified according to a second approach. The drying device is preceded by a corresponding device for removing, in particular the sizing agent, for example, a car wash. The car wash can also be used for other purposes.

Both solutions - the finishing with subsequent drying and washing with subsequent drying - have in common that the textile structures are treated with a fluid, wetted or soaked and subjected to a heat treatment after this step. Accordingly, the drying device is preferably immediately downstream of these pretreatment devices and Due to its design, it enables energy-efficient, fast drying of the corresponding textile.

The process according to the invention for drying textile structures in a textile treatment machine with a drying apparatus in which the textile structure is contact- and / or an impingement-dried after a pretreatment is characterized in that the textile structure is simultaneously contact- and impingement-dried in the same guide section. wherein this is guided over a heated cylinder and with drying medium from one of these at an angle, preferably of> 180 °, more preferably> 220 °, very particularly preferably> 265 ° enclosing hood is acted upon. A pretreatment may be understood to mean the treatment with a fluid, in particular sizing agent, impregnating agent, paint or a cleaning fluid. With regard to the advantages can be made to the comments on claim 1. By simultaneous combination of contact and convection drying in a drying section through the cylinder / hood assembly, the surface limit temperatures can be precisely tuned, thereby providing mutual support to the respective drying processes. Temperature gradient between cylinder and hood are avoided. This leads to increased specific water evaporation. The textile structure to be dried is thus not exposed to widely differing temperatures over long distances, but over a relatively short distance almost identical temperatures on both sides. The simultaneous two-sided exposure of the textile structure with the same temperatures or temperatures with a small difference has a positive influence on the quality and improves the operational safety.

The drying medium is blown onto the textile structure at temperatures in the range of in each case including 100 ° C to 200 ° C, preferably 150 ° C to 200 ° C. The energy consumption can be kept low. In a particularly advantageous manner, the exhaust air of the hood is guided in a recirculation system with optional coupling to an external dry medium source, wherein the exhaust air is heated directly or indirectly as a dry medium before entering the hood. By using the exhaust air heat, the energy balance of the entire machine can be significantly improved.

The solution according to the invention is explained below with reference to figures. It details the following:

DETAILED DESCRIPTION FIG. 1 illustrates, in a highly simplified schematic representation, a particularly advantageous embodiment of a textile treatment machine 1 according to the invention comprising at least one drying device 2. The textile treatment machine 1 is arranged and constructed to be suitable for textile structures, in particular linear textile structures 3, preferably warp threads or planar ones Textile structure 4, for example, to treat fabric or knitted fabric while passing through them. In the case shown, a textile treatment machine 1 for the treatment of linear textile structures 3 in the form of warp threads is reproduced by way of example. To clarify the individual directions is a coordinate system to the Textile treatment machine 1 created. The X-direction describes the longitudinal direction of the textile treatment machine 1 and coincides with the basic direction of implementation of the warp threads through them. Therefore, the X direction may also be referred to as machine direction MD. The Y-direction describes the direction perpendicular to the machine direction MD, ie width direction and is therefore also referred to as the cross-machine direction CD. The Z direction indicates the height direction.

The textile treatment machine 1 comprises a treatment device 9 in the form of a sizing device, in which the linear textile structures 3, in particular warp threads, are exposed to at least one fluid and at least one drying device 2 downstream of the device 9 in the feedthrough direction by the textile treatment machine 1. The drying device 2 is combined according to the invention Contact / Impingementtrocknungsvorrichtung executed, wherein contact and Impingementdrocknung on the warp threads in the same guide section by the textile processing machine 1 are effective. For this purpose, the drying device 2 comprises at least one rotatable heatable cylinder, here two cylinders 5, 6 which can be heated by steam, which are looped over a partial area of their outer circumference forming a distance a from a hood 7 and 8 emitting a drying medium. The wrap angle α is preferably selected such that it is> 180 °, preferably> 220 °, particularly preferably> 265 °. The textile treatment machine 1 can be part of a textile production plant or, as a separate device, can be used offline for the treatment of textile structures. In the case shown, the textile treatment machine 1 is exemplified as a weaving preparation machine and upstream of a weaving device, not shown.

The linear textile structures 3 in the form of warp threads are for this purpose of a Zettelwalzen- or Kettbaumablaufgestell 1 1 removed and the sizing device, which in the direction of passage through the Textile treatment machine 1 of the drying device 2 is arranged upstream. The individual warp threads are fanned out across the machine width. Depending on the design of the sizing device, the admission or treatment of the warp threads with sizing by spraying or dipping takes place. In the case shown, the treatment of the warp threads by dipping in a sizing bath 10. The warp threads are on dipping one or more times up and down and thereby wetted with sizing and then squeezed. Designs for sizing devices, in particular sizing baths are well known from the prior art, which is why not discussed in detail on it. The sizing agents used are, for example:

Starch, such as potato, wheat, rice and / or corn starch

- modified starch sizes

- egg whites

- natural sizing agents

- synthetic sizing

In order to dry the sizing agent relatively quickly and economically, after passing through the sizing bath 10, the warp threads are fed to the drying apparatus 2 and are guided on the outer circumference of the first cylinder 5 in direct contact therewith at a distance a from the hood 7. The leadership of the warp threads takes place here in direct contact with the writable from the outer circumference surface 12 of the cylinder 5. The warp threads are dried at the same time on the heated cylinder 5 directly and by means of the hood 7 discharged dry medium. The arrangement cylinder 5 and hood 7 describes a first drying section I. After passing through this is followed by a second drying section II, in which the warp threads are dried simultaneously via the heated cylinder 6 directly and by means of the hood 8 discharged dry medium. For this purpose, the warp threads are guided in direct contact with the surface 13 formed by the outer circumference of the cylinder 6 at a distance a to the hood 8. The individual hood 7, 8 has for this purpose in each case one around the circumference of the respective cylinder 5 and 6 and thus the surfaces 12 and 13 at a distance guided and correspondingly curved perforated inner shell, preferably perforated inner shell 14 and 15. During the guidance around the surface of the steam-heatable cylinders 5 and 6, the warp threads are or are acted upon via the width direction of the textile treatment machine 1 with drying medium, preferably drying gas.

The application of drying medium takes place as a function of the geometry, design and / or arrangement of the outlet openings for the drying medium which can be described by the perforation of the inner jacket of the individual hoods 7, 8 and the operating parameters of the drying medium.

In order to ensure a gentle drying, the drying device 2 of the textile treatment machine 1 is designed with the following parameters and operated operating parameters:

The diameter of the cylinders 5, 6 is in the range of each including 0.8 m to 2.5 m, preferably each including 1 m to 2 m.

The heating of the cylinder 5, 6 takes place by steam, which is preferably with a pressure below 5 bar in the cylinder 5, 6 can be introduced.

The distance of the perforated metal inner shell 14 to the surface 12 or 15 to the surface 13 is denoted by a and is in the range of 15 mm to 25 mm.

The drying medium acting through the perforation of the hoods 7, 8 in the wrap area is applied at temperatures in the range of in each case including 100 ° C. to 200 ° C., preferably in each case including 150 ° C. to 200 ° C. For this purpose, the individual hood 7 or 8 is associated with a dry medium supply system, which is shown here only schematically simplified as a box and is denoted by 16. In this case, a common dry-medium supply system 16 is preferably associated with both hoods 7 and 8. Other versions, ie with its own supply system are also conceivable. The hoods 7 and 8 are designed in the illustrated case as an integral unit. Each hood has at least one exhaust duct 17, 18 and both hoods 7, 8 have in the illustrated case a common supply channel 19, which is supplied via the common dry-medium supply system 16 with drying medium.

After passing through the drying device 2, further, the warp threads or textile fabric treating and / or ordering devices 20 may be provided within the textile treatment machine 1, for example, a tree device for accurately straightening the sized warp threads before the actual weaving process.

The embodiment in FIG. 1 is an example of linear textile structures 3. Such designs are generally arranged directly upstream of a textile production machine 22, in particular a weaving or knitting machine. This arrangement is shown schematically simplified in Figure 3a. The arrangement is preferably online. According to a second approach, however, it is also conceivable to carry out the textile treatment machine 1 for the treatment of planar textile structures 4. This relates in particular to the removal of the size after the production process of a flat structure 4, in particular after weaving. The execution of the drying device 1 with combined contact and impingement drying in the same guide section can be done by way of example as shown in FIG. Instead of the sizing bath 10, however, the drying device 2 is preceded, for example, by a washing system 21 for flat textile structures, such as woven, knitted or laid fabrics. Such an embodiment is shown by way of example in FIG. In this case, the flat structure 4, for example, after prior storage unwound from a roll and the textile treatment machine 1 are supplied. In this case, the textile treatment machine 1 of a textile manufacturing machine 22 is as in FIG. 3b shown, offline, ie subordinate spatially separated. It is also conceivable to remove the size immediately following the production process of the planar structure 4. In this case, the arrangement of the textile treatment machine 1 preferably takes place directly downstream of the textile production machine 22, ie online, as shown in FIG. 3c.

FIG. 4 illustrates a schematically simplified representation of a possible embodiment of a drying device 2 in a textile treatment machine 1. By way of example, the drying device 2 here has only one cylinder 5 which can be heated by steam and which is enclosed by a hood 7. Shown here is the dry medium supply system 16, which is coupled to the hood. This includes, for example, a fan 24 and a downstream of this heat exchanger 23 for heating the drying medium. The heat exchanger 23 is designed for this purpose, for example, as an air / waste heat exchanger, which in particular fresh air can be heated efficiently. Also shown here are the textile structure, in particular the flat textile structure 4 or the linear textile structures 3, which are guided around the cylinder 5 between the surface 12 and the hood 7. The exhaust air extraction takes place via exhaust air ducts 17, which can be coupled with an exhaust air extraction system, not shown here, in particular a device utilizing the exhaust air or the environment.

FIG. 5 illustrates an advantageous further development of a drying device 2 of a textile treatment machine 1. In this embodiment, the leadership of the textile structures to be dried, in particular the linear structure 3 or planar structure 4 via a plurality, preferably at least two steam-heated cylinder 5, 6, each of which in the circumferential direction, preferably at an angle> 180 ° enclosing Hood 7, 8 are subjected to drying medium. Shown here are in a particularly advantageous embodiment, the dry medium supply system 16, which with the exhaust air extraction system 25 under Forming a circuit 26 and thus a recirculation system can be coupled, with optional means 27 for at least partial or complete decoupling of a dry medium source 28 and / or the environment or an exhaust air utilization device of this are provided.

Here too, in a particularly advantageous manner, both hoods 7 and 8 are assigned a common dry-medium supply system 16. As a dry medium source 28 acts in addition to the exhaust air here a device for Frischluftansaugung, which are connected to the individual hoods 7 and 8 via corresponding means. In the case shown here, a flap system 29 is provided, which optionally connects the fresh air supply with the circuit 26 and thus allows the coupling with the individual supply channels 19.1, 19.2 to the individual hoods 7, 8 partially or completely. The flap system 29 serves depending on the used dry medium or the proportionate composition of fresh air and the partial release for fresh air. The hoods 7, 8 to be supplied drying medium is sucked in through a blower 24 and blown out and at least one heat exchanger 23 to the corresponding supply channels 19.1, 19.2 supplied. For coupling the exhaust air extraction system 25 with the dry medium supply system 16, the drying medium acting on the hood is withdrawn via corresponding exhaust ducts 17, 18 and recycled in the circuit 26 the Zuführkanälen19.1, 19.2. For this purpose, the exhaust air extraction system 25 is at least indirectly coupled to the supply channels 19.1, 19.2 and via appropriate control and regulating devices, here in the form of a flap system 30 control and / or regulated.

Instead of the fresh air supply, another means for supplying other drying gas may be provided.

The portion not remaining in the circuit 26 remaining exhaust air is blown through a blower 31. As already stated, the textile treatment machine in a textile manufacturing machine online - yes after use case upstream or downstream or offline as a separate machine spatially and functionally separated from this.

The inventive solution is not limited to the embodiment in Figures 1 to 5. Advantageous further developments, the same invention, in particular the simplified design of the drying device in the high-performance area concerning are included.
