Description

The present invention relates to a knitted or woven fabric in the form of a double-surface knitted fabric.

Such substances are well known. They are used for different purposes. They usually have an upper and a lower textile side, which are spaced apart to form a gap. For this purpose, it is known to provide spacer threads which span the intermediate space.

The object of the present invention is to further develop a knitted or woven fabric in the form of a double-surface knitted fabric in such a way that the air conditioning or the climate compensation is improved, in particular high moisture absorption and removal by the fabric and at the same time high air permeability through the fabric is. This is particularly advantageous for direct or indirect body contact, for example, when used as a reference fabrics on sitting or lying surfaces.

The problem is solved by a mesh or woven fabric according to claim 1 and a process for the preparation according to claim 15. Advantageous developments are given in claims 2 to 14.

The object is achieved according to claim 1 by a knitted or woven fabric in the form of a double-faced knitted fabric or knitted fabric with an upper and lower textile side, which are spaced apart to form a gap and with repeating in the longitudinal direction of the fabric or fabric transverse first and second Sections, wherein in the first section in each case at least one insert, in particular filler, is introduced and in the second section in each case at least one space spanning and spanning spacer thread is provided.

By means of such a substance, a particularly good absorption of moisture with simultaneously high air permeability can be ensured and thus a particularly advantageous air conditioning and moisture removal, in particular during direct or indirect body contact, take place. In this case, the first section is designed, in particular, to absorb moisture, and the second section is suitable in particular for allowing ventilation.

It is not just a simple combination of different types of fabrics, but just the special arrangement of the sections ensures a particularly good result.

With regard to the arrangement of the first and second sections, many possibilities are conceivable. In particular, however, it is preferred for manufacturing reasons to arrange them alternately transversely to the longitudinal direction of the material, ie transversely to the direction in which the material grows in the production, in particular adjacent to each other, in particular without interposition of other areas or sections.

Such a fabric can be produced, for example, on a knitting machine, in particular a circular knitting machine, in that a first group of systems generates the first sections and a second group of systems generates the second sections.

With particular advantage, therefore, the first and second sections are arranged adjacent to each other. This means that there are no other intermediate ones Areas are arranged and in particular always alternately first and second, first and second, first and second section, etc. alternate. Such an alternating sequence can be selected in the longitudinal direction of the material or transversely to the longitudinal direction of the material.

The individual sections are in the plan view of the upper or lower side in particular rectangular. The individual first and / or second sections are in the plan view of the upper or lower side in particular designed so that their extension in a first direction, in particular perpendicular to the longitudinal direction of the material, at least by a factor of 10, in particular at least 100 from the extension in the differs to the first direction vertical direction. The extension of the first and / or second sections in the first direction is in particular at least a factor of 10, in particular at least 20, smaller than the extent of the mesh or woven fabric in the direction in which the first and second sections alternate. The extension of the first and / or second sections in the direction perpendicular to the first direction is in particular identical to the extent of the mesh or woven fabric in the direction perpendicular to the first direction

As a result, row-shaped sections which are arranged adjacent to one another generally result.

In particular, at least 5, in particular at least 10, first section and at least 5, in particular at least 10, second section are provided over the extent of the mesh or woven fabric in the direction in which the first and second sections alternate.

In particular, the sections are each provided with over in the direction perpendicular to the first direction direction constant extent in the first direction. If the sections are arranged alternately in the longitudinal direction of the material, then in particular their respective width transversely to the longitudinal direction of the material over the fabric is advantageously constant. If the sections are each arranged alternately transversely to the longitudinal direction of the material, their respective width in the longitudinal direction of the material is advantageously constant over the fabric. With particular advantage is the width of the Sections significantly smaller, especially smaller than the fabric length selected. In particular, the widths of the sections are chosen smaller than 10% of the fabric width.

With particular advantage, all the first sections have a first width and all second sections have a second width, wherein this width is given in particular transversely to the longitudinal direction of the material, in particular if the sections alternate alternately transversely to the longitudinal direction of the material. However, the widths can also be given in the longitudinal direction of the material, in particular if the sections alternately alternate in the longitudinal direction of the material.

With particular advantage, the first width is equal to the second width selected and thus have the sections all an identical width. Usually, their length is also identical, since this extends over the entire length or width of the substance and thus is identical for cuboidal fabric dimensions.

With particular advantage, the first and / or second width is selected with 2 - 15 mm. Such section widths have proven to be particularly advantageous in terms of moisture absorption and ventilation. In such fabric widths a sufficient width of each section is selected to perform the function particularly reliable and effective and is also given a local moisture absorption and ventilation in all places particularly reliable.

With particular advantage, the maximum thickness of the mesh or woven fabric is selected with 2 - 15 mm. With particular advantage, the minimum thickness of the mesh or woven fabric with 2 - 15 mm is selected. Such thicknesses of the mesh or woven fabric have proven to be particularly advantageous for the fulfillment of the desired functionalities.

With particular advantage, however, the thickness of the mesh or woven fabric is not constant. In particular, the height of the knit or woven fabric at the first sections is chosen to be different from the height of the knit or woven fabric at the second sections. In the peripheral areas of sections leading to others Next sections are then usually resulting in increasing or decreasing thicknesses.

Such alternating maximum and minimum thicknesses of the sections have proven to be particularly advantageous and further promote the desired properties of the knitted or woven fabric.

With particular advantage, the thickness of the first section is chosen to be greater than that of the second section. With particular advantage, all first sections have a first thickness and all second sections have a second thickness. Here, a distinction can also be made in each case between a first minimum thickness and a first maximum thickness of the first portion and a second minimum thickness and a second maximum thickness of the second portions. Because the thickness is usually not constant over the width of the section, since at least in the edge regions of the sections which are adjacent to other sections, usually resulting in increasing or decreasing thicknesses.

The sections will thus not have a constant height over their extension in the first direction, at different section thicknesses of the first section and the second section, as the fabrics are somewhat flexible and thus in the transition region an increasing or decreasing thickness will be given. Thus, in particular, the minimum thickness of the first portion is chosen to be greater than the maximum thickness of the second portion.

With particular advantage, the respective thicknesses in the direction transverse to the first direction, in particular over the lengths of the sections, but constant.

With particular advantage, the intermediate space has a minimum and / or maximum height of 1 to 13 mm. Such thicknesses have proven to be particularly advantageous. On the one hand, maximum thicknesses are optimally not to be exceeded in order to ensure particularly good ventilation and, on the other hand, not too small minimum thicknesses are advantageous in order to ensure particularly efficient absorption of moisture, in particular via the insert. With particular advantage, therefore, minimum heights of the gap of at least 3 mm are particularly preferred.

With particular advantage, the at least one insert part, in particular designed as a filling thread, completely fills the height of the intermediate space and / or the extension of the first section in the first direction, in particular the width of the first section. By such a complete filling a special stability and a high moisture absorption capacity at a given height of the gap or width of the first section is ensured.

The features stated in relation to a first and / or second section are fulfilled, in particular with regard to at least half of the first or half of the second sections, in particular all first and second sections. In particular, all first sections are identical and all second sections are identical.

All first sections thus have at least one filling thread and all second sections at least one spacer thread.

With particular advantage, the at least one filling thread of each first section, which is not a section arranged on the edge of the fabric or woven fabric, adjoins the at least one spacer thread of the respectively adjacent second section on both sides. By such an immediate delimitation of the spacer thread adjacent second sections a particularly stable guidance of the filling thread is given. In particular, the marginal sections, in particular if there is no spacer thread in the first section and no thread extending between the upper and lower sides and anchored in the sides, are second sections. Marginal sections exist especially on two edges of the mesh or woven fabric. The third and fourth edges are formed in particular by alternating first and second section ends. By such a choice of marginal sections a leaching of the filling thread is avoided. For the filling thread is preferably not connected to the upper or lower side and / or in particular not to the spacer threads. Rather, it is preferably loose in the intermediate space and is only by adjacent elements, in particular upper side and lower side and spacer threads of adjacent second sections restricted in its free movement.

The filling thread can then, in particular if it completely fills the width of the first section, ie the width between the adjacent spacer threads, and optionally also completely fills the height of the intermediate section of the first section, and thus is largely in its position and extent fixed. This requires a high stability and high moisture absorption capacity.

With particular advantage, the extent of the filling thread in the direction of the height of the intermediate space is chosen to be greater than the height of the intermediate space in the second section. This results in an alternating height in the direction of the alternating sequence of the sections. As a result, a particularly efficient moisture absorption and ventilation can be ensured. This is due, for example, to the fact that the lower sections can ensure particularly effective ventilation since they are generally less pressurized when a person is sitting or lying on a mesh or woven fabric according to the invention, for example. In such a situation, the first sections which drop out in their height generally form a stronger contact with the person and can thus absorb moisture in a particularly efficient manner. Also, a wiping effect is achieved in movements of the person, which further promotes the moisture absorption ability.

With particular advantage, the mesh or woven fabric has a weight of 100-800 g / m ² . Such training has proven to be particularly advantageous for fulfilling the desired functionalities.

With particular advantage, no spacer thread and no thread anchored in the upper and / or lower side are provided in the first section. This results in that the filling thread, for example, is not penetrated by a spacer thread. This simplifies the production and allows a free choice of the filling thread and a special flexibility in height in the area of the first sections of the mesh or woven fabric. However, it is also conceivable to provide spacer threads also in the first section and, for example, the to arrange at least one filling thread between the individual spacer threads in the first section and / or to penetrate the at least one filler thread with spacer threads.

With particular advantage, the first and / or second sections have a width of 15-40 stitches. This has proved to be particularly advantageous for ensuring the desired functionalities.

With particular advantage, the at least one spacer thread is a monofilament and / or the at least one spacer thread is made of polyester. The at least one spacer thread advantageously has a thickness of 0.01 to 5 mm.

With particular advantage, the upper side is formed in particular of Lyocel and / or spun threads and / or the lower side is formed of polyester and / or formed from at least one multifilament. With particular advantage, the insert yarn is made of polyester and / or at least one bulky multifilament.

The knitted or woven fabric according to the invention can come in particular for use as a cover, for example mattress cover, automotive interior trim, seat cover or be used as bedding and / or be designed as such. Also, automobile seats may be formed therefrom or related thereto, or the mesh or woven fabric may be formed as an automotive seat cover. In such applications, the advantages of the mesh or woven fabric can be particularly useful.

The problem is solved by a corresponding use of the mesh or woven fabric according to the invention as a bedding, seat, upholstery or mattress cover, automotive interior trim or automobile seat.

The object is also achieved by a method for producing a knitted or woven fabric according to one of the claims, wherein for the production of a knitting machine, in particular a circular knitting machine, is used and various systems in the knitting machine form the first and second sections.

The object is also achieved by a method for producing a double-surface knitted or knitted fabric having an upper (1) and lower (2) textile side, which are spaced apart to form a gap, with repeating in longitudinal or transverse longitudinal direction first and second Sections, wherein for producing a knitting machine, in particular a circular knitting machine, comprising a plurality of system is used and a first set of systems forming the first sections and a second set of systems forming the second sections, wherein in each first section (7) at least one Inserting part (3) is introduced, and in the second portions (8) at least one of the gap (6) spanning and spanning spacer thread (4) is formed, characterized in that the extension of the filling thread in the direction of the height of the gap is greater than that Height of the gap in a second section.

In this case, the extent of the filling thread in the direction of the height of the intermediate space in at least one first section, in particular in all first sections is greater than the height of the intermediate space in at least one second section, in particular at least one adjacent and / or adjacent second section, in particular in all immediately adjacent and / or adjacent second sections, especially in all second sections.

In particular, the first set of systems is disjoint with the second set of systems. In particular, the first set of systems has a plurality of first subsets and the second set has a plurality of second subsets, and the first and second subsets are each alternately arranged so that a first subset is followed by a second subset followed by a first subset again. followed by a second subset again, etc.

In this case, the first subsets are in particular identically large and, in particular, the second subsets are identically large and, in particular, the first and second subsets are each identically large. In particular, the first amount and the second amount are the same size.

With particular advantage, the knitted or knitted fabric is formed exclusively by system which form first or second sections.
