Description

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 is treated with sizing agents to adhere to protruding fiber ends and to make the warp yarns more resistant. The finishing process is followed by drying with roller dryers or hot air. For drying textile linear structures themselves a variety of different methods is known. Both contact drying methods and impingement methods are used. In general, a main drying process step follows a pre-drying step.

From the publication DE 1 914 231 A is a drum dryer for linear textile structures in the form of warp threads is known, which is preceded by an apparatus for predrying with an over the entire width of the chain directed outlet slot and a suction slot arranged opposite. In this case, a perpendicular to the line-shaped textile structures blown out of the outlet slot 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 an apparatus for sizing and drying warp yarns in which the yarns coming from a plurality of warp beams are gathered and sized and then vertically split, pre-dried in a pre-drying section with hot air, recombined, final dried in a final drying section and wound up on a warp beam. 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.

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

US 4,025,993 In contrast, describes a device for finishing and then drying a group of threads, wherein the drying takes place in a contact dryer.

The publication DE 10100330 B4 discloses a method in which line-shaped textile structures in the direction of yarn travel are first passed over a contact dryer and then 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. The drying in several successive different drying steps is complicated and space-consuming. 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 planar 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, according to the invention is characterized in that the drying device comprises at least one rotatable heatable cylinder with a surface directly contacting the textile structure and a hood associated therewith , which is designed and arranged to be suitable to blow a drying medium onto the textile structure, wherein the at least one hood wraps around the at least one cylinder in the circumferential direction at a distance from 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.

Regarding the individual definitions of the different terms is on DIN 60000 referenced, the disclosure of which is fully included for these terms.

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 contact drying and 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 impingement drying 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 can be defined within the drying section in the feedthrough direction along the guide path and / or transversely thereto by the arrangement, geometry and / or design of the perforation of the inner casing 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 shell also allows an easily realizable possibility for active adjustment of a drying profile in different directions, for example via sliding plates, the depending on the position relative to the inner shell enlarge or reduce the exhaust ports.

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 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, associated with an exhaust system for coupling with the environment or an exhaust air utilization device. 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 can be coupled to the exhaust air extraction system 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 design of these over a portion of the outer circumference entwining and dry medium applying hood and thus of the overall system itself. The perforated metal inner shell can be better modified in terms of distribution and suction and the proportion of Luftleit-, distribution and intake elements are 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 arranged upstream of the drying device. This is a treatment device, by means of which a treatment liquid, for example an impregnating liquid on the. line-shaped textile structures by spraying or dipping before further processing is used 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 approaches - 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 become. Accordingly, the drying device is preferably immediately downstream of these pretreatment devices and, due to their design, enables energy-efficient rapid 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 heatable 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.
