Abstract

In a fixable textile sheet (1) comprising a support (2), based on a non-woven, woven or knitted fabric or the like, coated on at least one side with an adhesive mass (4), at least one additional layer (5) of fibers having a predetermined functionality is applied to the adhesive mass coating.

Description

The Invention relates to a fixable textile fabric, in particular usable as an interliner in the textile industry, with a wearer on Base of a nonwoven fabric, fabric, knitted fabric, knitted fabric or the like, which at least on one side with an adhesive coating is provided.

interlinings are the invisible scaffolding the clothing. They take care of correct fits and optimal comfort. Depending on the application support You increase the workability the functionality and stabilize the clothing. In addition to clothing, these can Functions in technical textile applications, e.g. Furniture, upholstery as well as the home textile industry Find application.

interlinings can made of nonwovens, fabrics, knitted or comparable textile sheets exist, usually in addition are provided with an adhesive mass, whereby the insert with a Outer material is usually thermally bonded by heat and / or pressure can (fixation). The insert is thus on an outer fabric fixed. The mentioned various textile fabrics have depending on the manufacturing process different property profiles. Fabrics consist of threads / yarns in warp and weft direction, knitted fabrics consist of threads / yarns, the above a stitch bond to a fabric are connected. Nonwovens consist of single fibers, which are thermal, mechanical or chemically bound. The different procedures for Production of textile fabrics are known and described in the patent literature.

The Outer fabrics used in clothing are also known after Process produced. To ensure the most homogeneous possible connection between To achieve outer fabric and interlining, the property profile must of the interlining to match that of the outer fabric. Important criteria in the classic application are the handle, the feel of the outer fabric / Einlagestoffverb, and, where appropriate, the adhesion of the interlining material to the outer fabric. Further requirements then arise in the care behavior of the outer fabric / Einlagestoff composite e.g. at the laundry or dry cleaning. Other important criteria in the application are the usability over one long period of time or the behavior of the liner in the garment in use. Functional properties of the interlining material can be applied to the Outer material transferred or its special features.

Examples for such Interlining with functional properties that have the properties of the outer material, are e.g. Interlining with elastic behavior. For elastic Outer fabrics are preferred interlining fabrics with stretch or elastic Behavior used. Another example is interlining with Water-repellent properties, e.g. similar hydrophobic properties of outer fabrics.

fixable Interlining usually consists of a textile carrier (fabric, Knitted fabric, nonwoven fabric, knitted fabric, etc.), which on one side with an adhesive composition coating is provided. The adhesive is thermal activatable and is usually made of thermoplastic polymers. The technology for applying these adhesive coatings on the carrier (e.g., powder dot, paste pressure, colon, lump, hot melt methods) are known and described in the patent literature.

adversely on the known fixable interlining is that the transmission a functional property of a carrier material on an outer material through between carriers and outer material adhesive coating is impaired. Furthermore, the possibilities very limited to transfer various functional properties.

task The invention is a fixable, textile fabric to create, in particular usable as fixable Einlagestoff in the textile industry, which regards the transfer functional properties, for example on an outer material, is optimized.

These Task is solved with a fixable textile fabric with all features of claim 1. Preferred embodiments are described in the subclaims.

According to the invention is in a fixable textile fabric, which in particular is usable as a fixable Einlagestoff in the textile industry and which one carrier based on a nonwoven fabric, fabric, knitted fabric, knitted or the like having, at least on one side with an adhesive coating is provided on the adhesive coating at least one additional Layer of fibers, which has a given functionality, applied.

following The invention is without limitation the general public by the example of the use of a fixable invention textile fabric described as a fixable Einlagestoff in the textile industry. The use of a fixable invention textile fabric however, is not limited to this application. Also other applications are conceivable, for example as a fixable textile fabric in home textiles, such as upholstered furniture, increased Seat constructions, e.g. For seat covers or fixable and stretchable fibrous webs in automotive trim. The following are readily applicable to other applications of the fixable invention textile fabric, e.g. the above, applicable.

in the fixed state, for example in clothing pieces, is the additional Fiber layer between the outer fabric and the carrier of the liner arranged. The fixation of the Einlagestoffes can, for example, with a in the textile industry usual Procedure (e.g., fixer). Depending on the fiber layer used receives thereby adding a functionality to the carrier material, additional functionality in the fixed state with the outer fabric. The functionality is for Outer fabric and can optimally through its close contact unfold their function. The introduced additional or modified functionality can provide a voluminous feel the insert, elasticity, Softness, touch, antistatic, color, odor control, water vapor permeability, Windproof, cushioning, Isolation, adhesion enhancement to the outer fabric or the like. These examples are exemplary and the achieved functionality is not limited to these examples. The functional properties of additional fiber layer and carrier can be the same and reinforce yourself or in different areas. So it can be beneficial be, both layers, i. carrier and additional fiber layer to form elastic to the outer fabric a increased elasticity to rent. An example for different functional properties are the water repellent finish of the support material and the production of the additional fiber layer of elastic fibers.

It has surprisingly been found in the present invention, that the fixable invention textile fabrics despite additional Fiber layer on the adhesive layer adheres very well to the outer fabric. The cover of the adhesive layer leads, as in the embodiments is still shown, obviously no significant reduction the adhesion to the outer fabric compared to an uncovered one Adhesive material layer. this could be due to that the thermally softened adhesive mass when fixing to the outer fabric the extra Fiber layer to the outer material at least partially penetrates and there for the bonding ensures.

on the other hand By the cover of the adhesive layer, the risk of sticking or interlocking of the layers to each other (interlining material / interlining material) reduced.

The Solution according to the invention allowed continue to standardize the carrier and adhesive layer with a later one Application of additional Fiber layer. This allows an economical way of production, since only in a late Process step again the properties of the fixable textile fabric changed can be.

When carrier for the Fixable according to the invention textile fabrics can Nonwoven fabrics, woven, knitted or crocheted or the like are used. The carrier can be single or multi-layered.

The Adhesive mass coating is usually by polymers, preferably formed thermoplastic polymers. The thermoplastic polymers for example polyester-polyamide, polyolefin or polyurethane or ethylvinyl acetate-based be. Combinations of the different polymers or blends are also possible.

The Adhesive mass coating can spread continuously over the entire surface of the carrier extend, but it can also be applied discontinuously, for example in the form of a dot pattern or the like.

Of the Adhesive mass order can over the adequate known methods (e.g., powder dot, paste printing, colon, Scattering, hotmelt process). Preference is given to a double-point method used, as achieved with this method a very good adhesion becomes. this could be due to that in this method, the adhesive mass very directed the additional Fiber layer penetrates. When using a colon procedure has the cover according to the invention the adhesive layer with an additional fiber layer the other Advantage that less adhesive particles can detach.

The additional fiber layer may be composed of one or more layers. The additional Fa serschicht or the individual layers may comprise natural and / or man-made fibers. Depending on the process, the applied fiber layer adheres to the carrier / adhesive composition by a stable mechanical and / or thermal entanglement (if the adhesive slightly melts). If desired, this composite can be additionally bonded chemically or via needles (mechanically or hydroentangled) even more intensively.

Examples for suitable Man-made fibers are polyesters, polyamides, regenerated cellulose fibers, Polyolefins, polyurethanes or their respective copolymers and variations, optionally in addition equipped with textile auxiliaries such as silicones, antistatic agents, etc. or in the fiber incorporated active ingredients (such as flame retardants, etc.). The chemical fibers can Staple fibers or direct melt spun endless (e.g., spunbond webs) or directly melt-spun finite fibers (e.g., meltblown fibers) be. Suitable polymers for The melt spinning process, for example, all known thermoplastic fiber-forming types. In particular, all fiber titers are suitable up to 10 dtex. With coarser ones Fiber titers, i. > 10 dtex increases fiber stiffness to the point that it usually does For this Purpose can no longer be used.

Especially suitable fiber titers are microfibers with a titer <1 dtex. It has have been shown that the additional fiber layer when using such Forming microfibers with a homogeneous dense structure, thereby also the functional property, e.g. a given elasticity, in the entire layer is formed homogeneously.

The most frequently used interlinings with functional properties are those which are suitable, the functionality "elastic behavior" on an outer fabric transferred to. Such interlining materials according to the invention have an additional fiber layer made of elastic Fibers on the adhesive mass side of the liner.

For this are especially melt-spun fine fibers made of elastic polymers suitable.

The elastic fine fibers are preferably by means of a spinning process produced. In particular, you can They are easier and cheaper Way directly spun on the adhesive mass coating of the liner as they usually end up hitting the pad sticky enough, even without further aids or measures good to stick to the surface.

Especially suitable for this purpose are melt spinning processes based on meltblown, because with these methods very fine-dense and homogeneous fiber structures can be obtained as a functional layer.

When melt-spinnable elastic polymers are in particular all fiber-forming elastic thermoplastics suitable, such as elastic copolyesters (e.g., copolyetherester), elastic copolyamides (e.g., polyether block copolyamides), particularly preferred elastic polyurethanes with aromatic and / or aliphatic Chains based on polyester, polyether and / or polycaprolactone chemistry.

A good bonding with the outer material is achieved in particular if the basis weight of the additional fiber layer does not exceed 30 g / m ² . With larger basis weights, the adhesion to the outer fabric generally decreases greatly as a result of the increasing coverage of the adhesive mass coating. For basis weights of less than 15 g / m ² , a particularly good adhesion is achieved. The specification of a lower limit for the weight per unit area does not make sense, since this depends on the desired effect, in particular also on the desired intensity of the functionality of the additional layer to be transferred. This can be easily determined by a person skilled in the art on the basis of a few routine experiments. In a further preferred embodiment of the invention, the fiber material of the additional fiber layer and / or the fixing temperature are chosen so that the fiber layer easily fuses during fixing with the outer material and thus contributes to the bond. In this case, a particularly good transfer of the functional properties of the interlining material can be achieved on the outer fabric, on the one hand by the use of the additional fiber layer, which either enhances the functional properties of the support material of the interlining or added to other functional properties, on the other by the very good adhesion due to the additional adhesive effect of the fibers. In this case, the thickness of the additional fiber layer is not limited to the above limit.

The respective melting points of the fiber polymers used of the additional fiber layer depend on the required property profile of the fixable interlining material. In order to ensure that in the application, for example, when smoothing a garment with a Einlagestoff invention, for example, with a very hot iron or intensive steaming of the garment, the fiber If the structure of the additional fiber layer does not melt, fiber polymers having a melting point greater than about 165 ° C should be used.

In the present application is the without limitation of generality most frequently used variant of a liner with one-sided adhesive coating described. However, the present invention is also applicable to such textile fixable fabrics applicable to a carrier with an adhesive coating on the front and back include. In such a textile fixable fabric can both on one and on both adhesive coatings additional according to the invention Fiber layers may be provided.

following The invention is without limitation the general public with reference to embodiments and the figure explained in more detail:

embodiments

In of Table 1 are for different interlining materials with different base materials and adhesive coatings the primary release force values of product examples without additional Fiber layers ("a" examples) and product examples each with an analogous structure, but with different additional fiber layers according to the present Invention ("b" examples) on the Haftmassenseite shown in direct comparison.

The Apply this additional Fiber layer was made by direct Bespinnen the adhesive mass side with a thermoplastic polymer with different basis weights at a meltblown plant.

The Fixation of the interlining substances listed in the table on one in-house batiste outer fabric was made on a continuous press at 140 ° C for one Duration of 12 sec. The separation force is determined by reference to DIN 54310 or DIN EN ISO 6330. The listed release force values are marked with "sp", if the adhesion of the outer fabric / interlining material is so strong during the release force test is that during the test execution the interlining rips, before a full peeling carried out is. This is a desired maximum value, since the liability in principle stronger is considered the internal strength of the interlining material. A peeling of the Layers, on the other hand, are marked "MW".

It can be seen that the insert fabric "b" according to the invention, despite covering the adhesive mass coating with an additional fiber layer, has quite comparable primary separation forces as the latter Insert fabric without additional fiber layer. The adhesion to the outer fabric is thus not affected despite coverage of the adhesive coating by the additional fiber layer.

The samples listed above were subjected to the tests described below with MI and M II using a Zwick testing machine. The measurement results are shown in Table 2.

• Measurement MI: the material is stretched in the transverse direction with approx. 3 N / 5cm and the percentage elongation determined at approx. 3 N / 5cm.

The elongation the product, i. the lack of return is in percentage change across from the original length specified. To determine this value, the sample body is a defined length recorded before the beginning of the measurement.

Table 2: Elasticity measurements on different samples

Measurements MI show that a standard nonwoven fabric sample 1a, although at a low strength but can be repeatedly stretched and relaxed, but one observes a significantly increased elongation after completion of this series of measurements compared to the interlining material sample 1b according to the invention. The measurement shows that the interlining material 1b according to the invention (with additional elastic fiber layer) has a markedly improved recovery capacity and thus significantly improved elastic properties than the conventionally constructed pattern 1a. Since both patterns, with the exception of the additional fiber layer in pattern 1b, have an analog structure, the above measurement results are a reliable proof that the good elastic properties of the inventive pattern 1b are due to the elastic properties of the additional fiber layer. When combined with an outer fabric, these are transferred to the outer fabric. Pattern C, which represents a commercially available bi-elastic fabric insert, and pattern D can be significantly less extensively stretched with these relatively small forces than the insert fabric according to the invention sample 1b and are thus disadvantaged compared to this.

at In measurement M II, the materials are stretched to an extent of 20% repeatedly charged. The insert fabric sample 1b according to the invention shows in accordance with the above measurement results good restoring forces at low strain forces. The elongation the material sample of sample 1b after passing through the measuring cycle is also low, which suggests a good recovery of the material. The standard nonwoven fabric Pattern 1a leaves Although repeatedly dilated, but the sample undergoes a very large elongation and has no repetition, i. the material is not elastic. This measurement also confirms the effect of the elastic according to the invention Additional fiber layer on the outer fabric.

template D can not sufficiently withstand the stresses and tears during the Exam. The product is not sufficiently stretchy and not elastic. The commercial Bielastic fabric insert pattern C undergoes elongation during measurement Materials, which makes higher and higher personnel must be spent. At the same time the elasticities are pulled out by the test. The material C, which is the state of the art for bi-elastic fabric inserts represents is thus for reversible strains of 20% not suitable.

In summary let yourself find that the measurement results in Tables 1 and 2 show that the interlining material according to the invention in terms of its attributable to the additional fiber layer good stretch and relaxation properties are clearly superior to conventional materials is. Furthermore, it can be seen that in the case of the interlining material according to the invention the adhesion to the outer fabric through the cover of the adhesive layer is not affected by the elastic additional fiber layer.
