Description

Process for the treatment of a textile substrate and devices for carrying out the process

The present invention relates to a method for the treatment of a textile substrate with the features of the preamble of patent claim 1 and to three devices for carrying out the method with the features of the preamble of claims 20, 34 and 39.

Textile treatment processes, for example pretreatment processes, dyeing processes or aftertreatment processes, are known in many ways and can be carried out continuously or batchwise in the context of textile finishing of textile substrates. These include, in particular, the washing, Abkoch-, Beuch- and bleaching method used in the context of pretreatment of the textile substrate, which carried out in the dyeing dyeing processes, which include a rewash of the dyed textile substrate, and Ausüstüstungsverfahren, with the help of each pretreated and / or dyed textile substrate by contacting it with a

Finishing agent, such as a plasticizer, a lubricant or an antistatic agent. The known methods used in this case and the devices used in this case are distinguished by the fact that they often require relatively high liquor ratios (weight of the treated product: volume of the treatment liquor), the liquor ratios being between 1: 0.8 and 1, depending on the particular treatment method: 20 vary. For example, EP 1 024 220 A1, which is based on the applicant of the present application, describes a treatment method for a

| Confirmation copy | textile substrate in which the textile substrate is wetted as an endless web strand with a treatment liquor and immediately thereafter the treatment liquor is squeezed out of the web strand, wherein the squeezed treatment liquor is collected separately from the web strand. In order to effect the required transport of the endless web strand, it is subjected to a gas stream and deposited in a web store, and thereafter rewetted with the treatment liquor. Although the known method and apparatus used for this purpose has prevailed and proven worldwide since its development about 18 years ago, in the known method at the beginning of the treatment the product web strand to be treated is wetted with an excess of treatment liquor and thereafter to a predetermined residual liquor Squeezed concentration, so that this correspondingly large-sized fleet management lines are required to supply the necessary for the networks treatment liquor volume and after

To dissipate nets of the web strand to be discharged, squeezed off treatment liquor, depending on the particular treatment and the respective textile substrate, the liquor temperature varies between about 60 ° C and about 140 ° C.

The present invention has for its object to provide a method of the type specified, which allows compared to the known method and to the known device, a still further improved economical treatment of textile substrates and this for the implementation of these treatment methods provide necessary devices. This object is achieved by a method with the characterizing features of claim 1, by a first device for carrying out the method according to the invention in a endless web strand aufgemachtes textile substrate with the characterizing features of claim 20, a second device for carrying out the method according to the invention in a as wide opened and reversibly transported fabric web winding with the characterizing features of claim 34 and a third device for carrying out the method solved in a set up as a fabric wrap textile substrate with the characterizing features of claim 39. The process according to the invention provides that, for the treatment of the textile substrate, it is arranged in a treatment apparatus and treated there with an aqueous treatment liquor which contains the chemicals and treatment agents required for the respective treatment in the concentration selected for the respective treatment. At the beginning of the treatment, the moisture of the textile substrate to be treated is adjusted to a value of 40% to 180%, in particular between 60% to 160%, based on the dry weight of the textile to be treated

Substrate set. Before, simultaneously herewith and / or thereafter, the textile substrate is heated to the temperature required for the respective treatment, without the actual treatment liquor being used for this purpose. Rather, the heating of the textile substrate, depending on the device used, the presentation of the textile substrate to be treated and the construction of the treatment apparatus by flowing the textile substrate with appropriately heated air or steam, in particular superheated steam, by heating the walls of the Treatment apparatus and thus radiant heat, via at least one arranged in the treatment apparatus heat exchanger and / or at least one infrared radiation source, wherein the term used previously term temperature for the respective treatment required initial temperature and the temperature during the treatment. In the next step, a treatment liquor volume to be set per unit time is used in the method according to the invention determined that the treatment liquor is passed through a bypass from at least one approach tank via a pressure pump, a flow meter and a control valve back into the at least one approach tank. As soon as the treatment liquor volume determined per unit of time is reliably determined and reproducibly set for the respective treatment, this treatment liquor volume determined per unit time for the respective treatment is sprayed onto the textile substrate linearly, progressively and / or degressively for the given treatment time, so that the treatment liquor volume Spraying this treatment liquor volume, the moisture content of the textile substrate during the treatment so far linear, progressive and / or degressive increased so that at the end of the treatment, the treated textile substrate has a final moisture value between 70% and 300%, especially between 140% and 260 %, based on the dry weight of the textile substrate to be treated.

During the spraying of the treatment liquor on the textile substrate, the textile substrate is transported at a uniform speed in the treatment apparatus as an endless web strand, reversing or transported as a web roll in the wide state, or when the textile substrate is opened as a roll of goods, the sprayed on treatment liquor the textile substrate transported by rotation of the fabric wrap. The non-absorbed treatment liquor deposited from the textile substrate during the treatment is separated from the textile substrate, collected and sprayed again until the predetermined treatment time has elapsed or the treatment liquor has been sprayed onto the textile substrate as far as possible.

For the above-described transport of the textile substrate during the spraying of the treatment liquor to be used in the method according to the invention, it should be noted that the web winding reversibly transported in the wide state denotes a transport of the web, in which the web wraps first in a broad condition to a first Roll wound and thereafter unwound during the spraying of the treatment liquor volume determined per unit time of the first roller and is wound on a second roller arranged parallel to the first roller, said winding and unwinding is repeated until the inventive method is completed. The treatment liquor volume determined per unit of time is then preferably carried out during the transport described above at a point at which the fabric web is present in a single layer between the two rolls in the wide state.

As used herein, the term "roll of goods" includes the presentation of the textile substrate as a sheet wound on a support or as a yarn wound on a yarn package, the textile substrate in this presentation being in a device having the features of claims 39 to 42 is treated by the method according to the invention.

During the spraying of the treatment liquor, if desired or necessary, the treatment temperature can be kept constant at a set temperature value or changed according to a predetermined temperature profile, wherein in the case of increasing the temperature this in particular on the previously preferably exposed heating elements and not or only in a small measure on the sprayed on treatment liquor and in the case of lowering the temperature here corresponding heat exchangers are assigned to the treatment apparatus.

Surprisingly, it has been found that, in the process according to the invention, one or more layers of water form on the surface of the textile substrate and / or in the textile substrate due to the moisture set at the beginning of the treatment, so that the respective treatment agent is set in the per unit time Behandlungsflot- tenvolumen is due to this water layer or water layers much more uniformly and faster distributed over the surface of the textile substrate and thus causes a particularly uniform treatment of the textile substrate with the respective treatment agent due to the view of the inventors. This can be followed in particular conspicuously if the respective treatment liquor contains as a treatment agent a colored substance, in particular a water-soluble dye, since it can be observed that even at the beginning of the treatment and over the entire period of time a uniform and thus level dyeing of the treated textile substrate results, which is maintained unchanged after completion of the process according to the invention.

The method according to the invention also has further advantages.

Due to the fact that, in the process according to the invention, relatively small volumes of treatment liquor are sprayed onto the textile substrate per unit time and this, as described above, is not or only to a lesser extent heated by the treatment liquor but by other heating sources, the process according to the invention compares to the cited prior art, a further improved efficiency. The small treatment liquor volumes can be conveyed in lines of correspondingly small dimensions, so that, on the one hand, the heating of these small volumes of treatment liquor requires a considerably lower energy requirement. Because of the lower dead volume falls in the inventive method at the end of the treatment, a lower residual liquor volume than wastewater, so that taking into account environmental aspects, the inventive method compared to the previously described known method both from the wastewater side and from the energy side significantly improved Environmental compatibility of the treatment of textile substrates with a treatment liquor allows. As a result of the lower water consumption, substantially less treatment agent residues and also less chemicals used to carry out the method 5 are discharged into the wastewater in the method according to the invention. Furthermore, it was found that the treated by the process according to the invention textile substrates in dyeing a higher dye from loot caused that also hereby foam-free dyeing can be performed and overall shorter overall processing times result, so that accordingly for Durchfühlt) tion of the method according to the invention and used below As compared to conventional devices, the devices according to the invention described have a lower power consumption, the productivity and availability of the devices is increased due to the shortened treatment times.

By way of clarification, it should be noted that the term treatment liquor used here denotes the liquor containing the actual treatment agent or the actual treatment agent in order to achieve the desired treatment purpose. In addition to these actual treatment agents, at

20 which are in particular surfactants, bleaching agents, dyes, plasticizers, antistatic agents, lubricants, water repellents and / or phil philierungsmittel, chemicals may still be included, such as wetting agents, carriers, leveling agents, dispersants, emulsifiers in the treatment liquor sometimes these chemicals

25 are referred to as textile auxiliaries and support the effectiveness of the treatment agents and / or their application to the textile substrate.

Furthermore, it should be noted that the term "and / or" used in the present description both additively and alternatively covers the individual elements of an enumeration so connected, so that these elements optionally with "and" or with "or" linked to be understood. Of course, the terms used in the singular also include the plural and the plural terms the singular.

The term "water" as used herein includes the water commonly referred to as hard and soft water in textile finishing and aqueous salt solutions and aqueous systems which are mixed with appropriate amounts of acids or alkalis to establish a desired pH.

Depending on the respective presentation of the textile substrate to be treated and the apparatus to be used for carrying out the method according to the invention, there are several possibilities for adjusting the moisture setting of the textile substrate to be treated at the beginning of the method according to the invention. A further development of the method according to the invention described above, in which the textile substrate is presented as an endless web strand or as a reversibly transported web wrap, suggests that at the beginning of the treatment, the moisture of the textile substrate to be treated is adjusted by the fact that a defined Water volume is sprayed during transport of the same, and that the endless web strand or the fabric web is transported for a predetermined time in the treatment apparatus until the textile substrate seen over its entire surface the moisture required at the beginning of the treatment between 40% and 180% , in particular a moisture between 60% and 160%, based on the dry weight of the textile substrate to be treated.

As an alternative to this, a variant of the method described above provides that in this case the textile substrate is also presented as an endless web strand or as a reversibly transported web roll and that at the beginning of the treatment, the textile substrate with water, in particular with heated water and / or saturated steam , wetted and that hereinafter a dewatering of the wetted textile substrate to the moisture to be set at the beginning of the treatment, as specified in the first characterizing feature (feature a) of claim 1) is performed.

If, however, the process according to the invention to be treated textile substrate opened as a roll of goods, so in a development of the method according to the invention at the beginning of the treatment, the moisture of the textile substrate to be treated adjusted by the fact that a defined volume of water is sprayed onto the textile substrate and that Ware wrap is rotated until the textile substrate has the required at the beginning uniform moisture between 40% and 180%, in particular a humidity between 60% and 160%, based on the dry weight of the textile substrate to be treated.

In particular, when the textile substrate has a particularly poor wetting behavior, for example because of its particularly dense construction, its high proportion of hydrophobic fibers and / or due to adhering, used during the fiber production, yarn production or fabric production or finishing Avivagen, is in a According to a further development of the method according to the invention, at least one wetting agent, preferably a non-foaming or only slightly foaming wetting agent, is added to the water to be sprayed on to adjust the moisture.

Is in the previously described embodiment of the method according to the invention, in which the textile substrate to be treated is first wetted with water and / or saturated steam and then to the initially required moisture between 40% and 180%, in particular between 60% and 160% (According to characterizing feature a) of the main claim) is set, is drained, so sees a development of According to the invention, the dehydration of the textile substrate is carried out by inflowing and / or passing through air, in particular with heated air. This refinement is always used when the textile substrate is treated as an endless web strand or as a web winding according to the method according to the invention, as described below in connection with the first device described in claims 20 to 33 and in patent claim 34 claimed second apparatus for performing the method is explained in detail.

With regard to the temperature at which the textile substrate to be treated is treated, it should be noted that this temperature depends on the type of treatment and on the type of fibers making up the textile substrate. If the textile substrate to be treated consists exclusively of synthetic fibers and if such a textile substrate is shrunk, washed, dyed, finished and / or softened, for example by the treatment according to the invention, the temperature of this treatment varies between 40 ° C and 140 ° C , in particular between 60 ° C and 130 ° C.

However, if the textile substrate consists of natural fibers and in this case according to the claimed method, this textile substrate is treated as described above for the textile substrates, which consist of synthetic fibers, the treatment temperature varies between 40 ° C and 110 here ° C.

Overall, therefore, it should be noted that the inventive method as such, regardless of the fiber substrate from which the textile substrate is made, the respective presentation of the textile substrate in the treatment, regardless of the treatment and regardless of the nature of the construction of the textile substrate can be carried out in a temperature range, in particular between 40 ° C and 140 ° C, so that accordingly a versatile device is to be designed so that the treatment apparatus, in which the respective treatment is carried out according to the inventive method, is preferably designed as a pressure vessel.

Regardless of which construction has the respective textile substrate to be treated, in particular a woven, knitted or knitted fabric or yarn, the moisture content of the textile substrate to be treated in particular varies at the beginning of the treatment

between 80% and 180% and preferably between 120% and 180%, in each case based on the dry weight of the textile to be treated

Substrates, these moisture values are preferably applicable to those textile substrates which consist exclusively of natural fibers or these natural fibers predominantly, i. at least 50% by weight and preferably at least 70% by weight.

In the development of the method according to the invention described above, the moisture of the textile substrate is then at the end of the treatment to a final moisture value during the treatment according to the invention by spraying the treatment liquor in particular between

180% and 300% and preferably between 180% and 250%, in each case based on the dry weight of the textile substrate to be treated, increased. However, if the textile substrate to be treated consists exclusively of synthetic fibers or predominantly contains these synthetic fibers, ie at least 50% by weight and preferably at least 70% by weight, the moisture content of the textile substrate to be treated is 40% to 120% at the beginning of the treatment %, preferably to 60% to 120%, in each case based on the dry weight of the textile substrate to be treated, while at the end of the treatment, the textile substrate has a final moisture value between 90% to 250%, preferably between 110% and 220%, in each case based on the dry weight of the textile substrate to be treated.

In particular, depending on the particular textile substrate to be treated the respective presentation and thus applicable for the respective treatment device and each treatment to be performed in the process according to the invention aufzusprühende per unit time treatment liquor volume between 1 l / min and 12 l / min, especially between 2 l / min and 8 l / min, varies.

The pressure with which the volume of the respective treatment liquor to be metered per unit time is sprayed in a linear, progressive and / or degressive manner varies in the inventive method between 1.5 bar and 6 bar, preferably between 2 bar and 4 bar. If the respective treatment of the textile substrate is carried out in a treatment apparatus, and the pressure in the treatment apparatus is above normal pressure and thus there is an overpressure in the treatment apparatus, then this excess pressure is added to the previously mentioned pressure of the treatment liquor to be sprayed.

As already stated above in the method according to the invention, in particular the textile substrate is heated throughout the treatment by appropriately introduced into the treatment apparatus tempered air and / or radiant heat to the respective required treatment temperature or it is thereby set a predetermined temperature profile. In particular, it is useful in the treatment of an endless web strand, by this used for the temperature of the textile substrate to be treated air at the same time for

Transport of the web strand by the device used for this purpose and to be described later. In particular, a pretreatment liquor, a bleaching liquor, an alkalizing liquor, a desizing liquor, an enzyme liquor, a dyeing liquor, a wash liquor, a soap liquor, an aftertreatment liquor and / or a softener liquor are selected as the treatment liquor in the process according to the invention.

In particular, in the method according to the invention as a textile substrate, a substrate made of cotton or a cotton-containing substrate is treated and in particular dyed with a, at least one reactive dye-containing dyeing liquor. If, in this embodiment of the method according to the invention, the pretreatment of this textile substrate consisting of cotton or cotton and preferably also the aftertreatment (soaps) is carried out by the method according to the invention, then the advantages mentioned in the beginning of the method according to the invention, in particular the saving of water and energy, to a very high degree.

These advantages are then further increased if, in the dyeing process with at least one reactive dye in conventional dyeing process required amount of salt used is reduced, the concentration of the reduced amount of salt between 0 g / l and 30 g / l dyeing liquor, in particular between 2 g / l and 30 g / l dyeing liquor varies. The present invention further relates to three devices for carrying out the method according to the invention described above.

The present invention furthermore relates to a first apparatus for carrying out the method according to the invention, wherein the first apparatus comprises a treatment apparatus, in particular a cylindrical container designed as a pressure body, for receiving the textile substrate to be treated in the form of an endless web of material

According to the invention, it is proposed in this device that, seen in the transport direction of the continuous web strand to be treated, the transport nozzle is arranged behind the reel, that the application nozzle is positioned for spraying the per unit time to be applied to the web strand treatment liquor volume in the reel and that reproduzierba- ren setting of the treatment liquor volume to be sprayed on per unit time of the application nozzle is associated with a bypass which comprises a bypass calibration line, a pressure pump, a flow meter, a first control valve, a second valve and at least one liquor receptacle.

Surprisingly, it was found that the first device according to the invention for carrying out the method according to the invention a very Energy-saving and fleet-saving treatment of the exposed as endless web strand textile substrate allows and at the same time ensures a reproducible and impeccable treatment results, without causing unegalities of the treatment effect, drip stains, different

Color failures in repetitive dyeing or damage such as irreversible wrinkles generated during treatment,

Fractures, grinding or blanching, occur. The inventors of the above device attribute these positive effects to the fact that the first device according to the invention performs the above-described arrangement of the reel in front of the transport nozzle and spraying the treatment liquor volume to be applied to the web strand per unit time by means of the application nozzle. Furthermore, the fact that the treatment liquor volume to be sprayed on per unit time at the beginning of the treatment is initially set exactly to a predetermined value and thereafter supplied only to the application nozzle and linearly, progressively and / or continuously adjusted with a transport speed matched to the respective textile substrate to be treated. or degressive sprayed. In a further development of the first device according to the invention, the liquor removal provided on the bottom side of the treatment apparatus is assigned to a liquor collection vessel, wherein when an adjustable level is exceeded, the rather small treatment liquor accumulated there is supplied to the liquor receptacle via a return conduit provided with a pump becomes. This liquor collecting container ensures that the treatment liquor not taken up by the web strand sprays uncontrollably during the filing of the web strand in the apparatus with the web strand after contact with the treatment liquor volume adjusted per unit time, since this liquor is collected on the bottom side via the liquor catcher and by means of a pump is returned to the liquor storage tank. Another development of the device according to the invention provides that in addition to the liquor receptacle a liquor preparation tank is provided which feeds the treatment liquor via a provided with a pressure pump and a metering line in the liquor receptacle, preferably in a per unit time adjustable volume. This liquor collection container allows, for example, in treatments that are carried out on the device according to the invention and in which several treatment liquors are sprayed with successive treatment on the continuous endless web continuously transported in the apparatus according to the invention, in the liquor preparation tank, so that without time interruption this treatment liquor change is made possible. In particular, in the first device according to the invention, the bypass calibration line is connected via a line extending between the bypass calibration line and the application nozzle and provided with a third valve, the pressure pump then with the first control valve open and the third valve open and with the second valve closed via the bypass calibration line the previously determined per unit time treatment liquor volume of the application nozzle continuously supplies.

In order to prevent in the apparatus according to the invention, as already stated above, that occurs after spraying the treatment liquor endlessly transported web strand during treatment not unabsorbed and deposited treatment liquor uncontrolled in contact, provides a development of the device according to the invention that in this case the bottom area the treatment apparatus is associated with an element which is designed as a goods storage for the web strand and in particular as a J-box, wherein the goods store or the J-box is provided on the bottom side with through openings, so that during the loading treatment unabsorbed and separated treatment liquor can not re-enter uncontrolled contact with the transported by the inventive device web strand again. Below this element, in particular, the previously described small-volume liquor collecting container with associated level control is provided.

In particular, in the device according to the invention, the reel is arranged in a housing connected to the treatment apparatus, the head of the application nozzle being positioned on the housing for spraying the treatment liquor. Thus, it is achieved in this particular arrangement that sprayed during the transport of the endless web strand through the machine via the head on the housing arranged application nozzle per unit time determined treatment liquor volume particularly evenly on the web of material to be treated.

A further embodiment of the first device according to the invention provides that a dewatering module and / or a further transport nozzle to be operated with the treatment liquor for the continuous web strand is or are arranged within the treatment apparatus.

In particular, if the treatment apparatus in addition to the air-operated transport nozzle still another, to be operated with treatment fleet transport nozzle for the web strand, such a device configured not only for the implementation of the inventive method but also as any conventional, in itself known treatment device applicable, since in this case the endless web strand can be operated continuously with the operated with treatment liquor transport nozzle during the known short liquor treatments. It should be expressly stated that this further, with treatment fleet to be operated transport nozzle for the web strand in the

Implementation of the method according to the invention, as described is not used, since the transport of goods required for the process according to the invention is carried out exclusively by the transport nozzle which is acted upon by a gas and in particular by air. In particular, this additional, to be operated with treatment fleet transport nozzle is arranged behind the reel seen in the transport direction of the respective web strand and can also in particular when performing the method according to the invention on this first device for dewatering the transported through the treatment apparatus endless web strand at the beginning of Treatment to a humidity between 40% to 180%, in particular between 60% to 160%, based on the dry weight of each endless web strand to be treated.

Preferably, the drainage module contained in the device according to the invention is designed such that it has a tube-like design

Guide for the web strand, which is so connected via a line with a side channel blower, in particular a frequency-controlled side channel blower, wherein the compressed about this and heated by a heat exchanger air is supplied to the web strand guide while at the same time from the web strand guide the web strand flow through the air withdrawn via a lint filter, a cooler and / or a water separator and discharged back to the side channel blower. In particular, the supply of the compressed heated air and the removal of the air flowing through the product web strand guide are arranged on opposite surfaces of the web strand guide. With regard to the configuration of this web strand guide, there are several possibilities. Thus, the first possibility provides that in this case the web strand guide of the dewatering module is designed as a pipe extending in the conveying direction of the continuous web strand. In order to exclude the risk of damage to the endless web of material to be drained during its transport through the web guide, preferably the inner surfaces of the web guide are partially or completely lined with a plastic material, in particular with a Teflon material.
