Description

The invention relates to a textile with a high Temperaturisolierwirkung breathable fabric of functional multi-component yarns and yarns for stabilization and / or structural design, wherein the functional multi-component yarn of synthetic yarn components is arranged in one lane in a multi-surface textile. The use of such trained textile sheet materials is seen primarily for use as Isolierrollo for at least one side open cooling shelves in the exhibition area of sales rooms, which can be covered or isolated in the non-promotional time with it in order to reduce the cold loss in the cooling rack during this time efficiently. But also the use in the production of textile wallpaper with a special thermal insulation and / or acoustic insulation is provided.

Such insulating fabric for use as Isolierrollo of refrigerated shelves are already known in practice. There are for this purpose textile webs, preferably ribbon fabric webs coated at least with an aluminum layer by means of vapor deposition. Such equipped webs are not only equipped with a low temperature insulation value but also vapor diffusion proof. As a result, due to the size of the temperature differences between room temperature and temperature in the cooling rack for condensation formation on the fabric web, wherein the forming condensation can reach the lower part of the cooling rack, which in turn must be avoided consuming.

The object of the invention is to provide a textile fabric web which overcomes the disadvantages of the prior art and also has an improved temperature insulation degree, if necessary can be equipped with or without vapor diffusion barrier and which can be continuously produced with conventional textile processing machines in a manufacturing process, wherein to be able to deal with technical and creative customer requests in an ideal and flexible manner, without the need for complicated preparatory work.

According to the invention the object is achieved by the features of claims 1 and 7, wherein the advantageous embodiments are described in the subclaims.

Thereafter, a textile with a high Temperaturisolierwirkung breathable fabric is a single lane as a multi-surface textile, so formed with multiple surface levels, with a filling weft is incorporated between the surface planes. The surface planes are formed from functional synthetic multicomponent yarns and have stabilization and / or structure-forming measures.

According to the invention, the multicomponent yarn used for producing the surface planes of the multi-surface textile consists of at least a first portion of yarn material having a defined melting temperature and a second portion of yarn content having a lower melting temperature than the melting temperature of the first portion of yarn material, wherein the multicomponent yarn is arranged in at least one of the formed surface planes. The filling weft between each two fabric surface planes is formed as a bulky filling as a result of the incorporation of the filling shot as texturized bulky recycled yarn left.

Furthermore, for stabilization and / or structural design, the formed individual surface planes partially and defined arranged connection shot is arranged so that it forms a textile plane connection between the outer surface planes, thereby the bulky filling includes and thus contributes to the dimensional stability and at the same time a pattern structure on the textile outer visible surfaces forms.

Both the multicomponent yarn and the yarn material for stabilization and / or structural design are arranged in an ordered distribution in the textile fabric in order to be able to create a defined quality and stability at the desired areas.

In order to achieve the desired properties of the fabric is between the yarns incorporated in the fabric as a result of one of the sheet structure and structure training subsequent thermal treatment of the prefabricated textile fabric, at least in the region of the ordered distribution of Mehrkomponentengarns a cohesive connection of both the constituents of the Mehrkomponentengarns and at least the Garnmaterialanteile formed for stabilization and / or structural design. The bulky filling is not affected by this measure, as long as it does not include multi-component yarns with a melting point range smaller than the temperature.

The cohesive connection in the region of the ordered arrangement of multicomponent yarns having a melting point range smaller than the temperature exposure is achieved by applying the multi-surface textile with a temperature until at least the lowest melting point of a yarn component of the multicomponent yarns used is reached. This leads to the dissolution of the yarn component structure and thus to the partial fusion and material bonding with adjacent yarn components and yarns, wherein a partial cohesive bond arises at these points within the textile structure, without resulting in a completely closed surface formation.

The fabric is provided by this arrangement and combination of yarns and yarn components within a sheet having the advantageous desired properties such as a very high vapor permeability as well as a very high heat insulating effect. In addition, with the choice of yarn component composition and the setting of the melting temperature of the multi-surface fabric, the degree of vapor permeability and, in addition to the choice and design of the filling weft, the effectiveness of the thermal insulating effect can be effectively varied and adjusted.

The textile fabric according to the invention can advantageously be fabric, knit, warp or knit fabric or Flachkulier with at least two technically separated from each other formed textile surface planes, which are connected by Füllschuss and / or structural and stabilizing bond between the textile surfaces and their different Yarn components are then at least partially fused together by means of temperature, be formed.

There is thus the possibility that the textile fabric according to the invention can be manufactured on the respectively customary production plants.

The possibility of arranging, in addition to the filling shot, a connecting thread bond with structure and stabilization formation, which is simultaneously incorporated in the production of the multi-surface textile, has the advantage that a dimensionally stable alignment and fixation between the individual surface planes prior to the achievement of cohesive bonds as a result of temperature exposure already in the production of Mehrflächengebildes he follows. The resulting textile level connections can be designed variably and also serve to form a structure on the surface of the textile fabric.

If the formation of the structural and stabilizing bond between the textile surfaces is staggered, there may be the advantage that, during the winding of the textile fabrics, there is no continuous superposition of the incorporated textile fabric joints. This can save a lot of space and the diameter can be reduced in the wound state.

Due to the possibility of differently used yarn qualities of the multicomponent yarns and their different integration in individual surface planes of the fabric can be achieved that the bond technically separated from each other formed textile surfaces have a different stiffness, which in turn for the handling of textile fabrics in practice a role can play.

When using the individual yarns for the surface formation, the filling weft and the connecting thread bindings, it is necessary for at least the multicomponent yarn to be a polyester, a polyamide yarn and / or a yarn with at least one meltable yarn component in order to achieve a cohesive connection of partial regions of the yarns used ,

The invention further includes a process for the production of the inventive textile with a high Temperaturisolierwirkung breathable fabric under processing engineering formation of a multi-surface textile when using synthetic Mehrkomponentengaren and a thermal aftertreatment.

Since the synthetic multicomponent yarns used for producing the multi-surface textile individual yarn components are equipped with different melting point temperatures, this property in the thermal after-treatment at least until reaching the lowest incorporated melting point to a subsequent partial cohesive connection between the incorporated in the fabric directly in contact with these yarn components incorporated yarn components ,

Advantageously, the formation of a multi-surface structure with a bulky filling, a fixation of the individual surface planes to each other before the temperature, the introduction of stabilizing compounds by connecting yarn bonds and the subsequent Temperaturbeaufschlagen with a partial formation of material between the yarns used and / or yarn components in a continuous process sequence using In special cases of use of the textile fabric in practice, it may be necessary that the classification of the synthetic multicomponent yarns within the fabric is defined locally. Then, however, the full-surface temperature exposure take place, since only where the multi-component yarns are arranged with their different melting behavior of the cohesive bond between the yarn components can be made partially.

In order to further improve the thermal insulation behavior of the textile fabric, it is necessary that as filling weft between the formed part planes of the fabric to prevent a cohesive connection of the two sub-levels of the fabric non-melting yarn material is introduced in fluffy or textured form. Although the bulky state is minimized when the multi-surface fabric is exposed to the temperature, it retains its positive effect on the resulting fabric with respect to its thermal insulation properties by including a large volume of air and using yarns of thermal insulation material.

This property can be influenced and adjusted by the variability of the chosen feedstocks, the bulking character of the filler material, and many other properties of the selected feedstock feedstocks.

For special applications, it may also be necessary that as filling shot between the formed part planes of the sheet to produce a cohesive connection of the two sub-levels of the fabric yarn material is introduced with a melting point in approximately the same temperature range as the lowest melting point temperature range of the multi-component yarn used. This superficially influences the vapor diffusion behavior of the textile fabric.

In order to increase the dimensional stability of the textile fabric, it may be necessary for the fabric to be additionally fixed during the thermal exposure, in spite of its containing stabilizing bond. But even with an additional pressurization during the thermal treatment, the desired properties can be varied.

The invention claims the realization of a structure formation from the predetermined, ordered incorporation of functional multicomponent yarns within one and the same production stage for textile surface formation, wherein structural stabilization is achieved by means of a subsequent thermal treatment from portions of the multicomponent yarn. Consequently, the incorporated functional multi-component yarn in the first process section "Textite surface formation" structure-forming component, from which in the second process section "thermal treatment" shares directly as structure-stabilizing components to be achieved product structure of a particular application product are obtained.

In the case of an ordered sequential incorporation of functional multicomponent yarns within the textile surface formation, a supplementary incorporation of additional yarns or yarn systems takes place, which need not be pronounced as multicomponent yarns.

The multicomponent yarn is preferably composed of polymeric yarn components. At least one polymer component has a significantly lower melting temperature than the other yarn components. By softening this yarn component by means of a thermal treatment, a targeted cohesive bonding is achieved between the further yarn components of the multicomponent yarn itself and also to further structure-forming yarns and yarn systems contained in the textile fabric. The multicomponent yarn can be formed as a core-coat combination yarn, as a fiber or filament blended yarn.

By precisely determining the location of incorporation of the multicomponent yarn within the textile surface forming process, textile-technological metering of the structure-stabilizing component components takes place directly in relation to the structure-forming portions of the multicomponent yarn as well as additionally contained, exclusively structure-forming yarn components within the textile constructions. This metering between multicomponent yarns and, if appropriate, fabric-forming yarn constituents which continue to be present in the fabric can be locally varied during the textile surface-forming process, resulting in areas with different stiffness / structural stability, heat-insulating property and / or vapor-permeable permeability by means of the subsequent thermal treatment in the finished product. In addition, the changing, locally defined incorporation of functional synthetic multicomponent yarns, which themselves have different yarn contents with lower and higher melting temperatures, provides a further possibility for the expression of variable structural stability.

Open structured textile fabrics, as they are known for example from the field of weaving by so-called Ajour bindings or from the field of knitting by so-called fillet bonds remain preserved by means of the described invention in their textile-technologically incorporated perforation. The incorporation of the multicomponent yarn can be carried out in such a predefined amount that the molten material fraction of the multicomponent yarn mainly cohesively connects the yarn components which are bonded together directly in their surface of incorporation in the surface forming process.

Textile-technological properties of the textile structure, such as air permeability or opacity, which are fundamentally incorporated in the surface-forming process, experience virtually no changes in the case of structural stabilization achieved according to the method.

The object of the invention is in the production of limp, textile products, using a z. B. polymeric matrix material in combination with a temperature imparted structural stability. There is no additional complex system technology for applying and joining structurally stabilizing materials with a textile base structure such as squeegee, calender, belt, in particular double belt dryer, combinations with belt presses or similar laminating techniques and commissioned works necessary. A significant simplification of the finishing processes compared to processes for stabilized with matrices fabric according to the prior art is the result.

This is explained in particular by the fact that the textile structure according to the invention completely eliminates the stress on the textile to be finished with a surface or line pressure for applying or introducing the structure-stabilizing component. An essential advantage of the method according to the invention is therefore that, with the restriction of the finishing process to the thermal treatment, a continuous working process with the least control or control effort is required. Only the thermal treatment, which is proportional to the component proportions of the material according to the invention with respect to the treatment duration and the treatment temperatures, is decisive for the structural stability in the finishing process.

The dosage of the stabilizing components is more precise, especially in typical, open-pored, permeable textile constructions. The advantage is that they are inherent to the textile fabric (inherent) and subject to any fluctuations due to a usually external, subsequent order on wavy textile surfaces. As a result, both material quantities and energy consumption are significantly reduced compared to the prior art.

A significant product-specific advantage of the invention in terms of freedom of design of the product structures results from the fact that the optical appearance of the invention produced and simultaneously refined textile almost exclusively results from its specially selected binding engineering design within the textile surface forming process and remains unimpaired by the finishing, since no external pressure must be exercised for the purpose of structural stabilization within the finishing process, unless it is intended, thereby only the material thickness of the resulting fabric is changed. Boundary-related high-low effects, reliefs to partial incorporations of motifs, e.g. By Jacquardbindungen or similar patterning methods in the textile manufacturing process remain in almost unchanged visibility preserved or can be highlighted by the targeted orderly incorporation of bi- or multi-component yarn in these areas even by the thermal treatment.

Other special incorporated functional yarns, e.g. B. electrically conductive materials remain unimpaired by a surrounding structural stabilization.

The invention will be explained in more detail below using an exemplary embodiment.

Embodiment:

What is needed is a suitable fabric having a very high heat insulating property and yet high vapor permeability, which can be produced in a working process with conventional processing machines in order to be effectively manufactured for use with refrigerated shelves.

For this purpose, this fabric is produced in one web on conventional weaving machines as a multi-surface fabric using functional synthetic multicomponent yarns, wherein the multicomponent yarn consists of a first Garnmaterialanteil with a defined melting temperature and a second Garnmaterialanteil with respect to the melting temperature of the first Garnmaterialanteils lower melting temperature. For this purpose, the commercially available multicomponent yarn with the name Pemotex, a polyester yarn, can preferably be used for this purpose both for the weft thread and for the warp thread or for both. It is necessary that at least in one of the resulting surface planes of the multi-surface fabric, the multi-component yarn is arranged as polyester yarn. Between each two resulting surface planes of the multi-surface textile, a filling shot of textured, bulky trained polyester yarn is arranged, whereby initially a bulky filling is formed. For stabilization and also for structure formation, the outer surface planes formed are connected to one another by a connecting thread binding during the production process, and thus both the position of the surface planes relative to one another and the weft filling between the surface planes are fixed relative to one another. In this case, both the multi-component yarn and the yarn material for stabilization and / or structural design are arranged in an ordered distribution in the textile fabric. As a result, a targeted shape and surface stability of the multi-surface textile is achieved before a surface or partial temperature exposure of the multi-surface fabric formed takes place. The temperature setting for the application is chosen so that at least the lowest incorporated melting temperature point of a yarn component of the incorporated multi-component yarn is achieved. It is thereby achieved that between the yarns incorporated in the textile fabric as a result of a subsequent formation of the fabric and structure formation subsequent thermal treatment of the prefabricated textile fabric, at least in the region of the ordered distribution of the multi-component yarn a cohesive connection both the constituents of the multi-component yarn and at least the yarn material components for stabilization and / or structural design is formed.

The textile Mehrflächengebilde is formed in this case as a fabric. However, it is also possible to form the multi-surface textile as a knitted fabric, warp or Nähgewirk or Flachkulier, but with at least two binding technology separately formed textile surface planes, which kept separate by means of filling shot from each other and procedurally connected by means of structural and stabilizing bond (connecting thread binding) are and their different yarn components are then fused together by means of temperature application at least partially.

It may be advantageous that the formation of the structural and stabilizing bond between the outer textile surfaces, which is designed as a connecting thread binding, is arranged offset within the textile surface. This not only visually achieves a plastic structure, it is also the space-saving Aufrollfähigkeit the textile fabric achieved. This can also be assisted by the fact that the textile surfaces which are formed separately from one another by bonding technology have a different stiffness.

The synthetic functional multicomponent yarns used in the production of multi-surface fabric with their different individual yarn components with different melting temperature points, have the advantage that in the thermal aftertreatment subsequent partial cohesive compound targeted between selected incorporated yarn components, as well as if desired the stabilization and patterning yarn produces and is introduced into the textile structure. In this case, the classification of the synthetic multicomponent yarns within the fabric can also be locally defined and carried out in order to optimally align the textile fabric of the invention to the specific applications.

For optimum alignment with the heat or cold insulation, a textured and / or bulky non-melting or a yarn material equipped with a higher melting point than the temperature application is introduced as a filling weft between the formed textile surface planes of the fabric to prevent a cohesive connection of these layers. With the introduced Füllschussgarnqualität and its quantity, the heat or Kälteisolierverhalten can be set very differentiated to the desired value. With a configured use of tailored to the particular application Mehrkomponentengaren and their temperature behavior, the surface of the textile fabric according to the invention can be optimally adapted to the desired or necessary vapor diffusion capacity. The greater the proportion of cohesive connections in the tissue surfaces and / or higher the thread density and arrangement in the tissue construction, the lower the vapor permeability.

With the solution according to the invention, it is possible to produce a textile fabric optimally matched to the customer's wishes, which effectively meets the customer's wishes with regard to temperature insulating effect and vapor permeability.
