Description

1334827 IX. Description of the Invention: [Technical Field] The present invention relates to a fixable textile fabric, in particular, as a lining material for the A-woven industry, having a carrier, which is a non-woven fabric, a shuttle A woven fabric, a knitted fabric, a woven fabric or the like is provided with an adhesive coating on at least one side of the carrier. [Prior Art] The lining material is an invisible bracket of clothing. They are responsible for making the right fit shape and achieving the best #wear comfort. They are designed to help them add J1, improve functionality, and stabilize clothing. In addition to clothing, these functions can be found in industrial applications such as furniture, mats and home textiles. . The lining material may be composed of a non-woven fabric 'woven fabric, woven fabric (Gewirke) or equivalent textile fabric material'. These materials are mostly provided with an additional material, so that the inner lining layer can be combined with a table cloth (oberstoff). f heating and / or pressure) bonding (fixing the inner liner). Therefore, the inner liner is fixed to a table cloth. The different textile fabrics mentioned above also have different property distribution curves (Eigenschaftsprofil) depending on the manufacturing procedure. The woven fabric is composed of yarns/yarns along the warp and weft directions, and the woven fabric is composed of yarns/yarns which are joined by a combination of yarn loops (Maschen, English: sthch) to form a textile fabric. Nonwovens are composed of individual fibers which are combined thermally, mechanically or chemically. These methods of making textile fabrics are well known and are found in various patents. The table cloth used in the clothes is manufactured by the same conventional method. In order to make the bonding between the 5 table cloth and the lining material as uniform as possible, the property distribution curve of the lining material is matched with the property distribution curve of the table cloth. Important criteria in traditional applications are the feel of the hand, the cloth/liner combination of Haptik, and possibly the adhesion of the lining material to the table cloth. Other requirements are the warranty properties of the combination of the table/liner material (e.g., when washing or cleaning with chemicals). An important benchmark for other applications is the nature of the material that is lining the garment during prolonged use and when in use. The function of the lining material can be transferred to the table cloth or contribute to its characteristics. Examples of such lining materials which are useful for such enamels (which contribute to the nature of the table cloth) are lining materials having elastic properties. For elastic surfaces, lining materials with tensile or elastic properties should be used. Another example is a lining material having water-repellent properties which, for example, contribute to the similar suspicion properties of the table cloth. The squeezable lining material is generally composed of a textile carrier (woven fabric, woven fabric, non-woven fabric, knitted fabric, etc.). The carrier-side has an adhesive coating. The adhesive material can be thermally activated, and generally the technique of applying the thermoplastic polymer coating to the carrier (for example, powder dot method, paste p brush, double point method, dispersion method, hot melt method) is a conventional one. And seen in the case of Xu Li. The disadvantages of these conventionally fixable lining materials are: _ material one: the effect of the force energy property on a table cloth is affected by the carrier and the intervening coating. In addition, the ability to transmit a variety of different functional properties is greatly limited. Qualitative [Explanation] 6 1334827 The purpose of the month is to provide a fixable spinning that can be used as a textile. I, σ cloth material, its special nature of the transmission. : Example: a fixed internal material, which is functionalized. (For example, the best effect on the effect of the transmission to the surface cloth is to use a fixed textile 1 with the patent application scope! The fabric has a feature patent. The preferred embodiment is described in the application. The invention provides a fixable textile fabric, in particular, a lining material for industrial use, having a carrier, which is woven. Based on a woven fabric, a knitted fabric, a woven fabric or the like, at least one side of the carrier is provided with an adhesive coating, wherein at least one additional fibrous layer is applied to the adhesive coating layer. Having a pre-set functionality. The following uses the fixed textile fabric of the present invention as a fixable lining material in the textile industry as an example to illustrate the invention, but does not limit the general scope of the invention. The fixable fabric of the invention is not limited to this application. Other applications are also conceivable, for example in the case of home textiles (Heimtextil) as a fixable textile fabric such as padded furniture, reinforcing seat structure' It is used as a seat covering or a fixed and stretchable fiber cloth in automotive design. The following embodiments can also be directly applied to the application of the sturdy textile fabric of the present invention (for example, the above). In the state (for example, in clothes), the additional fiber layer is provided between the surface cloth and the carrier of the inner liner. For example, the fixing of the lining material can be carried out by a method conventionally used in the textile industry (for example, "fixed press") In this way, depending on the fiber layer used, in the state of being fixed to the table cloth, 7 1334827 is added to the additional functionality which is added to the functionality of the carrier material. This function is for the table cloth, and The intimate contact can be utilized to best perform its function. The additional or varying functionality added can be the volume of the inner layer of the touch (Haptik), softness, hand, antistatic, color, Odor resistance (Geruchshemmung) 'Water vapor permeability, wind tightness impermeability, impulsiveness, insulation (heat), adhesion to table cloth, or similar properties. These examples are only examples, the functionality achieved is not limited These examples. The functional properties of the additional fiber layer and the carrier may be the same and thus may be additive or different. Therefore, the two layers '', ie the carrier and the additional fiber layer, are designed to be elastic', giving the table cloth a higher elasticity, An example of different functional properties is the water-repellent structure of the carrier material and the additional fiber layer made of elastic fibers. In the present invention, it has unexpectedly been shown that although there are additional fiber layers on the layer of adherent material, the invention The fixable textile fabric can still be attached to the surface layer very well. As will be explained in the scope of the embodiment, the adhesive layer is covered, which is not obvious compared to the uncovered adhesive layer.地: The adhesion of the enamel to the table cloth is significantly reduced. The reason is probably that the heat-softened applicator is 'at least partially saturated with the additional fiber layer to the table cloth when it is fixed to the table cloth, and is used for sticking at the place. Pick up. On the other hand, by covering the adhesive layer, it is possible to avoid the bonding of each & lining material/liner material to each other. Furthermore, the solution of the present invention results in a standard production of the carrier and the attachment layer: application of the additional fibrous layer. This can make the production method very good: only; * later program steps' the properties of the fixable textile fabric can be changed again. / For use in the present invention, it can be fixed as a non-woven fabric, a woven fabric, a woven fabric, or a single layer or a plurality of layers. A carrier for textile fabrics can be knitted or the like. The carrier can

The sorbent layer is typically formed from a polymer (especially θ 勒 initial [special 疋 thermoplastic polymer). "For the column, the thermoplastic polymer may be based on polyester, polyamine, polyurethane or ethyl vinyl acetate. Combinations or mixtures of polymers are also available. The coating may extend continuously over the entire surface of the carrier, but may be applied discontinuously, e.g., in the form of a dot pattern or the like. The application of the attachment material may be achieved by conventional methods (e.g., powder point method). Paste printing, two-point method, and scattering method. It is better to use the two-point method' because a good adhesion can be achieved by this method. The original: presumably in this method, the attached material penetrates the direction very directionally. Additional fibrous layer. When using the two-point method, 'covering the adhesive layer with an additional fibrous layer according to the invention' has the additional advantage that less adherent particles are torn off. The additional fibrous layer It may be composed of one or several layers. The additional fibrous layer or suitable individual layers may comprise natural fibers and/or chemical fibers, each of which is carried out according to a procedure, and the applied fibrous layer utilizes stable mechanical and/or thermal properties. Style The hook material of the filler is slightly melted and adhered to the carrier/attach material composite. This composite material may be additionally densely bonded, if necessary, by chemical means or by needle rolling (mechanical or water column bonding). Examples of chemical fibers of the field include polyester, polyamide, cellulose regenerated fibers, polyolefins, polyurethanes or copolymers thereof and alterations thereof, such as 1334827, if necessary, additional textile adjuvants such as a decane oxime, an antistatic agent, etc., or a functional property (such as a fire retardant, etc.) processed into a fiber. The chemical fiber may be a short fiber (Stapelfaser) or a directly melted endless fiber (for example, a spunbonded nonwoven fabric) or a direct melt spun. Ended fibers (for example, meltblown fibers). Polymers suitable for use in the spinning process, for example, t, are all types of thermoplastic = fiber-forming fibers. Applicators especially for all fiber deniers up to the fraction of Germans ( When the fiber fineness is coarser, that is, >l〇dtex, the fiber toughness is greatly increased, so that they are generally no longer used for this purpose. Particularly suitable fiber fineness is microfiber of denier dtex. Indeed, the additional fibrous layer is formed with a uniform dense structure when such microfibers are used, such that the functional properties, such as the predetermined elasticity, are uniformly formed throughout the layer. The most commonly used functional properties The lining material is adapted to transfer the functional elastic behavior to a surface fabric which, according to the invention, has an additional fibrous layer of elastic fibers on the side of the lining material. Particularly suitable for this purpose are melt-spun fine fibers composed of an elastic polymer. The elastic fine fibers are preferably produced by a spinning method, and they can be directly spun into the adhesive covering of the lining material in a simple and inexpensive manner, because they generally have sufficient viscosity when running out to the bottom layer, even if there is no Other adjuvants or measures still adhere well to the bottom layer. Particularly suitable for this purpose is the Meltblown-based solution spinning method' because the functional layer obtained by this method has a fineness and a uniform fiber structure. 10 1334827 Suitable as a soluble spun elastic polymer, in particular all elastic thermoplastic materials capable of forming fibers, such as: elastic copolyesters (for example copolyetheresters), elastomeric copolyamines (for example polyether block copolyamines), Particularly preferred are elastomeric polyurethanes having an aromatic bond and/or an aliphatic chain, which are based on poly-, poly- and poly-caprolactone chemistry.

If the basis weight of the additional fibrous layer does not exceed 3 〇g/m2, it is particularly likely to be firmly bonded to the table cloth. When the weight per unit area is larger, since the coating of the adhering material covers more, the adhesion to the surface cloth is greatly reduced. When the basis weight is less than 15 g/m2, a better attachment can be achieved. It is not meaningful to set the lower limit of the weight per unit area. Because this lower limit is related to the desired density. This can be obtained by a simple routine using a routine experiment. In another preferred embodiment of the present invention, the fibrous material and/or the fixing temperature of the additional fibrous layer is selected such that the fibrous layer is easily melted when fixed to the surface cloth, thereby facilitating bonding together, in which case The functional properties of the lining material can be particularly well transferred to the table cloth, on the one hand by the use of the additional fibrous layer, which enhances the functional properties of the carrier material of the lining material or complements other functional properties, The aspect is due to the excellent adhesion caused by the additional adhesion of the fibers, in which case the thickness of the additional fibrous layer is not limited to the threshold values given above. The respective melting points of the fibrous polymer used in the additional fibrous layer are dependent on the desired property profile of the lining material to be fixed. In order to ensure that when a garment such as a lining material of the invention is used for ironing, for example, with a very hot bucket, when the garment is densely steamed (Aufdampfen), the additional fibrous layer Fiber structure is not 11 丄 334827

It will be dazzled, so the sleek point of the fiber polymer used is higher than the change of about H = case Γ 'Describes the most commonly used modification of the lining material of a masking material, but does not limit the co-communism of the present invention. Features are here. However, the present invention also uses some fixed textile σ 蚂. . The cloth materials 'they contain a carrier, and the front side and the back side have an adhesive coating. In the case of the grading of the sturdy textile fabric, the additional fibrous layer of the invention may be provided on only one of the coatings or on the coating. The present invention will be described in detail below with reference to the drawings and drawings, but not limited thereto. VIII. In Table 1, the lining materials with different basic materials and coatings are selected on the side of the attached material without the additional fiber layer. Examples and similar constructions are provided on the side of the adhesive. The primary separation force values for the products of the various additional fiber layers (bf examples) according to the invention are for direct comparison. ^This additional fiber layer is applied by directly coating the adherent layer on a meltblown device with a thermoplastic polymer of different basis weights. The lining material shown in the table is fixed on a typical Batist table cloth on a continuous press at 14 (TC is 12 seconds. The knife force is measured by the German industry. Standard DIN or 〇ΙΝ 6330. If the value is required, the above separation force value is expressed by “Sp.” When the separation force is measured, the surface cloth/liner material has a strong adhesion. Therefore, when measuring The inner liner is torn before the complete peeling (Abschalung), which is the maximum value sought because the adhesion is substantially stronger than the intrinsic strength of the lining material. Conversely, if the layer is detached, use 12 1334827 MW".

Therefore, the effect of adhering to the table cloth, although covered with an additional fibrous layer, is not affected.

In Table 2, it is to be demonstrated that the functional properties of the additional fiber layer are transferred to the effect of the long one, which shows the results of the elastic measurement of the inner material composed of different materials with and without the additional fiber layer. The following samples were made: Sample lb: A non-woven fabric containing 70% polyamide short fiber (^) or 30% polyester short fiber (17 dtex), 25 g/m 2 consolidated with ps and 9 g/square The melamine-attached material was applied by a double-point method using a cp 52 printing template to apply 1 Gg/m 2 of polyurethane urethane to the additionally applied fiber layer (similar to sample lb of Table 1). La. A non-woven fabric on the market, which contains 70% polyamide short fiber and is coated with a 9 gram/m2 polyamine adhesive according to the dual method using a -cp 52 printing die (similar to sample U in Table 1). 100% polyester yarn, with a cp 52 sample c: a kind of woven fabric that is commonly seen on the market, consisting of (dteX3318, linen combination, 24 g/m2 printing stamper as a two-point method 甭 0 * / τ times Covering 9 g/m2 of polyamidamine-like imprinted D-type non-woven fabric on the market, consisting of 100% polyamidamine 4827 moment fiber (丨jdtex), 35 g/m2, using ps generation solid, and using -cP 52 The printing template was applied by a two-point method to a 1 g/m2 polybromide attachment. The above sample was tested by a kneading machine (the following test) ΜΙ & ΜΠ indicates. The measurement results are shown in Table 2. Measurement M1: The material was stretched in the transverse direction with a force of about 3 N/5 cm and the percentage of stretch at the face (10) was measured. After this test, the cloth was allowed to relax. And repeat the test ten times in the same sample. The data measured after -, five, and ten times are shown in "2." After ten measurements, it can be determined whether the sample/cloth is still being pulled in this measurement. Long.

This measurement shows that the lining material 1 b of the present invention (elastic The additional fiber layer) has better Erholung ability and elastic properties than the traditionally constructed sample la Since the construction of the two samples is similar except for the additional fiber layer of the sample b, the above measurement does prove that the good elastic properties of the sample (lb) of the present invention are attributed to the elastic properties of the additional fiber layer. When combined with a table cloth, this property is transferred to the table cloth. Sample c [which is a market-used bielastisch I woven lining] and sample D utilizes this smaller force comparable to the present invention. The lining material sample d has a much smaller degree of stretching and is therefore more disadvantageous than the present invention. In the sample ΜΠ, the material has a tensile load of up to 2% by weight. The lining sample of the present invention is consistent with the above measurement results. The small tensile force has a good recovery force mb. The length of the material sample is also small after the measurement cycle. This shows that the material has a good recovery. Although the standard non-woven sample la can be repeatedly stretched, However, the specimen has a large elongation and cannot be repeated, in other words, the material is not elastic. This measurement shows that the elastic additional fiber layer acts on the table cloth according to the present invention. Sample D does not Fully withstand this stress and tear during testing. This is not enough to stretch and inelastic. This kind of bi-elastic woven fabric sample C is used to test the S to take up the material, so it needs to be used more and more Big power. Elasticity test was used. Sample c (it #雔1 shows the technique of using the inner layer of the elastic woven fabric), so it is unsuitable to cooperate with 2% of the reversible 19 1334827. The conclusion can be determined. The measurement results of Table 1 and Table 2 show that the present invention The lining material is far superior to conventional materials in terms of its good tensile and relaxing properties (due to the additional fiber layer). Further, it can be seen that in the internal view (4) of the present invention, the property f of the attached list cloth is not affected by covering the adhesive layer with the elastic additional fiber layer.
