Definitions
- the invention relates to a textile fabric, preferably made of a voluminous nonwoven fabric, preferably carrying a functional agent, and to a method for producing the fabric and its use.
- Bulky nonwoven fabrics that have a solidifying fiber mesh layer on one or both sides are e.g. known from DE 198 12 499 AI.
- the nonwoven fabric, which is mesh-coated on one side has a mesh layer as the basic fabric and a plush-like surface that is formed from protruding fibers.
- the nonwoven, which is mesh-coated on one side is produced by producing a voluminous nonwoven, which is mesh-coated on both sides, and separated centrally in one plane.
- DE 42 39 469 AI is concerned with a method for consolidating cross-oriented nonwovens, in which a so-called nonwoven fabric is also coated on one side.
- Another technology for producing a meshed, voluminous nonwoven is known from EP 1 149 882 AI.
- This nonwoven fabric is designed as a textile carrier for an adhesive tape and has a velor-coated surface which is produced by a needle process and which is suitable, inter alia, for the function of reducing pressure forces.
- the velorized surface is formed from a multiplicity of parallel, essentially equally long fiber parts arranged perpendicular to the nonwoven web, the foot end of which is anchored in the nonwoven web.
- the adhesive of the adhesive tape is provided on the surface of the nonwoven web opposite the velor surface.
- Voluminous non-woven fabrics made on one side or on both sides are also used as pressure-elastic upholstery fabrics.
- the upholstery fabrics are placed between e.g. consisting of a woolen material and a e.g. arranged from polyurethane foam core. In particular, they should ensure pressure elasticity and be moisture-storing and moisture-permeable (EP 0 126 798 B1).
- DE 44 24 636 C2 discloses a multi-layer, voluminous laminating nonwoven fabric to be used as an upholstery fabric, in which two stitchbonding nonwovens are connected by vertical fiber plugs which consist of the fiber parts of the outer fiber mesh layers and which extend to the middle of the respective opposite fiber layer , This is to create a pressure-elastic zone in the respective fiber layer by means of a denser fiber arrangement.
- the padding known from DE 4127337 AI has, inter alia, a nonwoven fabric which contains a superabsorbent hydrogel as the functional fabric.
- the hydrophilic hydrogel is said to absorb large amounts of moisture and steam on the one hand and on the other hand to be easily regenerable, in particular desorbable. No statement is made about the type of nonwoven.
- a cushion of a seat or a piece of reclining furniture which has a desorbing moisture store in the form of a hydrophilic layer for the reversible absorption of body moisture.
- the hydrophilic layer consists among other things of a nonwoven fabric as the carrier material and a superabsorber polymerized onto the nonwoven fabric, the fibers of the nonwoven fabric being at least partially covered by the superabsorber.
- the superabsorber is sprayed onto the nonwoven fabric before it is polymerized or applied using the immersion bath process. No information is given in this document about the type of nonwoven.
- the superabsorbent When sprayed on, the superabsorbent penetrates inhomogeneously deep into the nonwoven fabric and is also distributed inhomogeneously on the surface. The result is extreme surface roughness and undesirable stiffening of the nonwoven. In addition, it is also not possible to apply defined amounts of superabsorbent, so that the absorption capacity cannot be regulated.
- the object of the invention is to create a pressure-elastic fabric, in particular usable as an upholstery fabric, in particular made of a nonwoven fabric, which in particular can contain defined amounts of functional agents in a homogeneously distributed manner, with defined nonwoven fabric properties such as suppleness and / or flexibility (elastic bending rigidity) and / or softness and / or pressure elasticity can be guaranteed.
- Vacuum elasticity property of a bulky fabric is understood in the context of the invention to include in an action of pressure or pressure load ⁇ äuf a surface of the fabric, the pressing force by elastic deformation of structural elements in the volume structure of the fabric and to ensure during the discharge that the deformed Spring back elastic elements.
- the pressure-elastic behavior of the textile fabrics is determined by the method known for elastic foams.
- the textile fabrics according to the invention in particular in the form of a nonwoven fabric, have a fiber pile layer with high pressure elasticity and in particular also with other functional properties and are used e.g. as a polyurethane foam substitute in vehicle interiors, in the upholstered furniture industry and as a flexible, functional textile material in the clothing, medical and insulation sectors.
- nonwovens with a three-dimensional fiber arrangement due to a structurally determined proportion of fiber parts with a vertical to diagonal arrangement to the nonwoven cross section, offer greater resistance to pressure loads than conventional nonwovens with a largely horizontal fiber arrangement in the nonwoven cross section.
- Such nonwovens with a three-dimensional arrangement are known in the art as Struto, as a web of fibers laid in longitudinal folds, consolidated by binding fibers, as diluted nonwovens with subsequent ejection of vertical fiber parts from the cross-section of nonwovens by piercing barbed needles, as Kunit as a longitudinally compressed fiber web consolidated by fiber meshes.
- thermoplastic binding fibers To improve the pressure elasticity of such three-dimensionally oriented nonwoven fabrics, the use of thermoplastic binding fibers is proposed, for example, in DE 202 09 709 U1. During thermal treatment, these binding fibers form small binding surfaces with and between the fiber parts, including the fiber parts that protrude vertically or obliquely from the cross-section of the nonwoven fabric, and can therefore make it difficult to turn them over under pressure loads.
- these connecting points having a connecting effect are also uniformly distributed in the same and, if the proportion is too high, an excessive number of such binding points leads to hardening and stiffening of the nonwoven fabric.
- the use of such binding fibers is often undesirable for such nonwovens with three-dimensional fiber orientation for economic and / or functional reasons, e.g. if use or processing temperatures occur that are above the melting range of the binding fibers.
- a nonwoven fabric with three-dimensional fiber orientation which consists of a nonwoven fabric consolidated by thread meshes and which has on one side a fiber pile layer which is formed from fiber parts which project vertically to the nonwoven fabric cross section and which have one over the entire surface have high density, parallelism and uniform height, with one or both ends of the fiber parts being mechanically integrated in the nonwoven cross section.
- a disadvantage of these nonwovens, in addition to the low pressure elasticity, is that only a maximum fiber pile height of 6 mm is achieved and the fiber parts in the fiber pile layer are not connected to one another for support.
- DE 100 47 824 Cl describes a nonwoven fabric made of fiber material without additional threads for use as a sub-upholstery material, which has a voluminous pile structure made of fiber parts with a spatial-diagonal arrangement, which is covered on one side with stitches in order to ensure the transverse strength of the nonwoven fabric to improve. It is disadvantageous that with these nonwovens there is a large difference between the pile fiber heights, which causes a very uneven surface of the pile fiber layer and which also negatively influences the pressure elasticity of the nonwoven fabric.
- the pile fiber surface of a Kunit nonwoven bonded by fiber meshes can also be used to form fiber meshes.
- the resulting multiknit nonwoven then has two fiber mesh surfaces with a certain thickness uniformity, but has diagonally oriented fiber parts between these two fiber mesh layers, the height of which is too low for good pressure elasticity effects.
- a voluminous nonwoven fabric that is mesh-strengthened on one side is selected and modified in such a way that a predetermined pressure elasticity is guaranteed during manufacture and, if necessary, a predetermined amount of functional agent can be attached to pile fibers or pile fibers and / or can be introduced into cavities between the pile fibers ,
- a new structure of the nonwoven fabric is created in the form of a voluminous, one-sided mesh-coated or mesh-strengthened nonwoven fabric with pile fibers and / or pile fiber loops protruding from the stitch layer perpendicular to the surface plane or to the cross-section of the nonwoven fabric, which at least three in the plane of the fabric has different structural levels, of which an inner structural layer forms, for example, a penetration barrier for a functional agent and an outer structural layer is predetermined Provides cavities for receiving functional means and predetermined polar fiber surfaces for the attachment of functional means.
- the void volume, the void distribution and / or the size of the attachment surfaces of the fibers can be predetermined in the manufacture of the new nonwoven, so that the nonwovens according to the invention can be easily adapted to specified requirements.
- FIGS. 1 to 6 of the drawing show schematically in cross section the structure of voluminous fabrics according to the invention.
- a voluminous nonwoven fabric 1 consists of a voluminous nonwoven fabric 1 and has a three-layer structure. At the bottom is a base layer 2 - the so-called nonwoven cross-section - with fiber parts 3 aligned essentially in the plane of the surface. On the underside, it contains the surface-strengthening fiber and / or thread mesh 4 and anchors the partially. Anchoring regions 5, 6 also extending in the plane of the surface and seated in the base layer 2, of longer pole fibers 7 and shorter pole fibers 8 projecting mainly perpendicularly from the base layer 2, the pole fibers 7 being arranged at a lateral distance from the pole fibers 8.
- the pile fibers 7 have at least predominantly the same pile tip height H of the pile tips 9, measured from the lower surface 10 of the textile fabric, or the pile tips 9 of the pile fibers 7 lie at least predominantly in a surface plane 12.
- the pile tips 11 have Pole fibers 8 at least predominantly have the same pole tip height h, measured from the lower surface 10, or the pole tips 11 of the pile fibers 8 lie at least predominantly in a surface plane 13.
- the plane 12 of the pile fiber Point 9 lies - viewed from the lower surface 10 of the mesh plane 14 - above the plane 13 of the pile fiber tips 11.
- the spatial distribution of the short fibers 8 is e.g. chosen so close that e.g. almost no functional means, e.g. in the form of an adsorbent can penetrate into the pile fiber structure of the pile fibers 8 or into the cavities 16 when a functional agent is filled into the cavities 16, the pole tips 11 blocking the penetration of functional agents.
- the nonwoven properties are retained in the nonwoven area 17, which consists of the short fiber layer area and the area of the base layer 2.
- This layer structure ensures, in particular, the pressure elasticity and flexibility and softness of the nonwoven that are desired for many applications.
- the long fiber layer region 18 provided over the short fiber layer provides the cavities 15 e.g. for receiving functional means and for the functional means accessible attachment surfaces of the long pile fibers 7 are available.
- a functional layer 19 is applied to the nonwoven fabric on the side of the plane 12, the thickness of which can be selected and which can extend to the tips 11 of the short pile fibers 8 and is solidified, the cavities 15 being at least partially filled and the long ones Pole fibers 7 are integrated in this area.
- the closed functional layer essentially has the functional task of fixing the free end regions of the pile fibers or pile fiber loops of pile fibers 7 or integrally fixing them in place, so that the pile fibers or pile fiber loops are clamped on two sides, namely once in the base layer or in the nonwoven cross section 2 and on the other hand in the functional layer 19.
- This clamping causes surprisingly a high pressure elasticity of the nonwoven.
- the pile fibers can only bend or buckle under pressure, but spring back elastically into their starting position when pressure is released. Even with long-lasting pressure loads, the pile fibers clamped on both sides do not lose their elasticity, so that the nonwoven fabric has excellent resilience with high dimensional stability.
- the short pile fibers 8 can increase the resistance to the pressure load when the functional layer 19 meets the pile fiber tips 11 of the pile fibers 8, when the functional layer 19 is arranged above the pile fiber tips 11. In the event that the functional layer 19 is seated on the pile fiber tips 11, the short pile fibers 8 reinforce the resistance to pressure loads and support the elastic springback.
- the functional layer can also take on an additional task, namely if it has functional means, such as Contains moisture or liquid absorbent, or consists of a functional agent.
- the functional layer is preferably applied by spraying.
- the application can also be done with an immersion bath process.
- the nonwoven fabric according to the invention is expediently sprayed with a superabsorbent polymer, a so-called superabsorbent.
- superabsorbers are electrolyte networks that can absorb and store large amounts of liquid and can easily desorb them.
- nonwovens with more than two levels of pile fiber tips and the correspondingly different cavity volumes It is also within the scope of the invention to provide pile fiber loops instead of pile fibers or pile fibers in combination with pile fiber loops, for example pile fibers being produced in one layer and pile fiber loops in another layer.
- a textile fabric according to the invention can be produced, for example, by the so-called Kunit process.
- a nonwoven fabric with a fiber pile structure on one side and with a fiber mesh structure on the other surface side is formed from a fiber pile with longitudinally or transversely oriented fibers.
- Compression of the fibrous web 1 4 to 1:10 vibration stroke of the brush 80 to 70 mm area dimensions of the nonwoven 100 to 800 g / m 2
- the structure of the nonwoven fabric according to the invention for the spray application of functional agents can be achieved by special adjustment of the compression and the oscillation stroke.
- a further possibility for producing a nonwoven fabric according to the invention is a two-step process with the production of a nonwoven bonded by fiber or thread meshing with predominantly transverse orientation of the fibers by cross-paneling the rolled web before mechanical bonding by stitching (Malivlies) or sewing over (Maliwatt). Subsequently, in this nonwoven fabric with barb needles piercing perpendicularly to the nonwoven fabric surface, the fiber pile layers or fiber pile structures are formed by removing protruding fiber parts from the nonwoven fabric cross section. With this method it is also possible to use a longitudinally oriented fiber web.
- the different heights and the different number of protruding fiber parts for forming the structure of the nonwoven according to the invention is achieved by the number of needles and the type of needles, especially the distance between the needle tip and the first barb.
- a high degree of pressure elasticity is achieved simply by the adhesive effect of the functional elements entered in the receiving spaces 15.
- tel layer 19 achieved on the long pile fiber threads in the area of the pile tips 9.
- the structure When there is a pressure load on the surface of the fabric, the structure deforms, with the short pile fibers 8 also elastically deflecting laterally, being supported against one another due to a correspondingly high number per square centimeter, and springing back elastically when the pressure load is released.
- the long-pole fibers 7 provide considerable additional support because they are integrated in the base layer 2 and in the functional layer 19 and resist a lateral pressure exerted by the short-pole fibers 8.
- the short-pile fibers 8 ensure a synergistic effect in that they form a barrier against the penetration of functional agents on the one hand and on the other hand form the cavity 15 for functional agents in combination with the long fibers and ensure pressure elasticity or pressure resistance of the fabric.
- the functional layer 19 can also have a synergistic effect. On the one hand, it ensures the desired function, e.g. the absorption and desorption or odor binding or the like, and on the other hand it forms an elastic membrane-like surface by the integration of the long-pole fibers 7, which guarantees pressure elasticity.
- the surface of the functional layer 19 is relatively smooth, so that the flat structure e.g. when used as an upholstery fabric, can be pulled onto an upholstery core without additional lubricant. With conventional upholstery materials, an additional sliding coating often has to be applied for this purpose.
- Example 1 The relatively smooth surface of the mesh layer of the base layer 2 is particularly well suited for lamination with an upholstery material.
- Example 1 The relatively smooth surface of the mesh layer of the base layer 2 is particularly well suited for lamination with an upholstery material.
- a fiber mixture of 60% polyester fibers with a fineness of 3, 6 dtex and a fiber length of 60 mm and 40% of polyester fibers with a fineness of 4.4 dtex and a fiber length of 36 mm is used for the formation of fiber pile.
- a double pile with a mass of 36 g / m 2 is formed and knitted on a Kunit sewing machine with a compression ratio of 1: 8 and a swing stroke of the brush of 48 mm with a mesh size of 18 F.
- the result is a voluminous nonwoven fabric with a mass per unit area of 280 g / m 2 and a total thickness of 4.8 mm.
- the height h of the pole tips 11 corresponding to the nonwoven fabric thickness of 4.8 mm is 3.2 mm. This results in a ratio of the height H to the height h of 1.5 to 1.
- the cross-sectional area of the receiving spaces 15 provided for the functional agent attachment is calculated with an average number of long pile fibers 7 of 7,000 per cm 2 of nonwoven fabric area to 0.98875 cm 2 per cm 2 . With an average number of short pile fibers 8 of 9,000 per cm 2 of nonwoven fabric area, the cross-sectional area of the interstices 16 has a value of 0.96085 cm 2 per cm 2 of nonwoven fabric.
- the ratio of the cross-sectional areas of the receiving spaces 15 to the cross-sectional area of the intermediate spaces 16 is thus 1.021 to 1.
- the pile fibers 7 are firmly embedded in a functional layer 19 made of a super absorber, which has a thickness of 1.2 mm. Before the functional layer 19 was applied, the permanent deformation was 40.5%. It decreased to 25% due to the functional layer.
- the voluminous nonwoven fabric consists of a cross-layer nonwoven reinforced by fiber mesh, which is then treated with long and short pile fibers with barb needles vertically piercing through the nonwoven fabric cross section in order to achieve the special pile fiber structure.
- the nonwoven also known as Mali fleece consists of a fiber mesh underside and horizontally arranged fibers made of polyester fibers with a fiber fineness of 3.3 dtex, a fiber length of 50 mm and a basis weight of 240 g / m 2 , a thickness of 1.8 mm and a course density of 14 course rows each 25 mm and a stitch length of 1.6 mm. This Mali fleece is then needled on two structuring needle machines with the following parameters:
- Machine 1 insertion side of fiber mesh side
- Machine 2 insertion side of fiber mesh side
- height H is 3.6 mm
- height h is 2.4 mm
- the thickness of the fiber mesh layer is 1.2 mm.
- the short pile fibers (8) are arranged exclusively from the horizontally arranged fibers, with a density corresponding to the type of needle and stitch density of 7200 fiber parts per cm 2 .
- the long pile fibers (7) are driven out at a density of 4000 fiber parts per cm 2 of nonwoven.
- the ratio of H to h is calculated with a value of 1.5 to 1.
- the long pile fibers 7 are firmly embedded in a functional layer 19 made of a super absorber.
- the thickness of the layer 19 is 1.4 mm.
- the nonwoven had a permanent set of 38%. It was reduced to 26% by the functional layer.
- the aim of the invention is achieved by the non-textile functional layer 19, which e.g. itself does not have to have elastic properties.
- the functional layer preferably also has its own spring-like or rubber-like elasticity, which supports the elasticity of the elastic structure of the textile fabric.
- the functional layer not only fulfills the fiber-binding function and not only has inherent elasticity, if necessary, but also consists of a material which acts as a so-called functional agent.
- the functional layer can have good climatic and / or clothing-physiological properties, such as, for example, water storage and / or water vapor absorption and / or water vapor permeability and / or air permeability and / or odor binding and / or odor formation (fragrance) and / or heat conduction and / or thermal insulation.
- the functional layer 19 has thicknesses between 1 and 4 mm, in particular between 1.1 and 3 mm.
- the object of the invention is achieved not only by using a voluminous textile fabric, in particular in the form of a nonwoven fabric with different lengths of pile fiber according to FIG. 1, but also with fabrics, in particular in the form of nonwovens with a uniform pile pile layer.
- a fiber pile layer with a predominant proportion should expediently be present therein, the same length of fiber parts projecting vertically to diagonally from the nonwoven cross section, which are held together in the upper part which is furthest away from the nonwoven cross section by the flat, connecting, non-textile functional layer 19 in such a way that in the event of pressure loads Although the nonwoven material is pressed in and compressed in the area of the fiber pile layer, the fiber parts of the fiber pile layer are not folded over with little repetition effect.
- the high pressure-elastic effect of such a flat fiber integration in the upper part of the fiber pile layer results from the relatively thin, non-textile functional layer. It is important for the good pressure elasticity that a certain free movable height of the individual fiber parts of the fiber pile layer remains in the area between the cross-sectional area of the fabric or the cross-section of nonwoven fabric and the underside of the non-textile Functional layer. In addition, it is favorable to assign further processing and use properties, as described above, to this non-textile, functional layer incorporating partial fiber areas on the basis of a material selection.
- the pressure-elastic nonwoven fabric shown in FIG. 2 consists of the nonwoven fabric cross section 21 and the pile fiber layer 22.
- the pile fiber layer 22 has the fiber parts 23 projecting vertically to diagonally from the nonwoven fabric cross section 21 with free fiber part ends 24 or fiber part loops 25 in the area furthest away from the nonwoven material cross section 21.
- the e.g. Channel-like cavities 28 in the elastic partial area 27 of the fiber pile layer 22 offer space for the forwarding and / or storage of gaseous or liquid media and space for storing non-textile, solid, particle-shaped functional means (not shown).
- the pressure-elastic nonwoven fabric shown schematically in cross section in FIG. 3 consists of a Kunit nonwoven fabric made of polyester fibers with a fineness of 3.3 dtex and a fiber length of 90 mm. It has a mass of 380 g / m 2 and a total thickness of 5.6 mm.
- the fiber pile layer 22 contains 280 g / m 2 of fiber mass, with a thickness of the fibers forming the nonwoven cross section 21 Mesh layer 29 of 1.2 mm, the fiber pile layer 22 has a thickness of 4.4 mm.
- a super absorber was sprayed on, which thus forms the non-textile functional layer 26 and has a mass of 100 g / m 2 and a thickness of 1.4 mm.
- this non-textile functional layer 80% of the free fiber part ends 24 and fiber part loops 25 contained in the fiber pile layer 22 are firmly integrated.
- the nonwoven construction according to the invention results in a significant increase in water vapor absorption due to the type and amount of the non-textile functional layer 26 and the moisture storage capacity as important functional properties for the use of the nonwoven according to the invention as a climatically outstandingly suitable cushion component for vehicle seats.
- the corresponding test values are summarized below: Property of Kunit nonwoven fabric according to pressure-elastic nonwoven

- This construction according to the invention consisting of a textile fabric with pole layer 22 and applied non-textile functional layer 26, results in addition to the high moisture transport and high moisture storage caused by the superabsorbent of the functional layer 26, and a reduction in the permanent deformation originally present in the textile fabric by 65% after use-related pressure load.
- the pressure-elastic textile fabric according to the invention consists of a pile knitted fabric made of polyamide filament yarn and has a mass per unit area of 190 g / m 2 and a thickness of 3.0 mm.
- the pile layer 22 formed from filament parts 23 contains 120 g / m 2 of filament yarn mass and the Pole layer 22 has a thickness of 2.3 mm.
- the surface of the pole layer 22 is glued with a polyamide adhesive film with a mass per unit area of 50 g / m 2 in such a way that this adhesive film with a thickness of 0.7 mm forms the non-textile functional layer 26 and thereby 85% of all free Fila 24 the pole layer 22 firmly integrates.
- This integration according to the invention in combination with the textile construction results in a high pressure elasticity and low permanent deformation with regard to the use of the pressure-elastic textile fabric as a seat cushion component.
