Definitions

  • the present invention relates to a yarn for the production of preferably three-dimensionally deformable textile fabrics, such as woven fabrics, knitted fabrics or knitted fabrics, and a method for producing this yarn.
  • a preferably three-dimensional deformation of a textile fabric can e.g. by deep drawing, but also by other techniques known per se.
  • Such textile fabrics are e.g. needed as an outer layer or cladding for the interior of motor vehicles and very generally for the cladding of molded plastic parts.
  • the textile fabric can e.g. placed over a metallic inner panel of a door or pressed onto the surface and applied with adhesive.
  • Such textile fabrics can also be used as a covering for furnishings or wherever an uneven, for example relief-like surface is to be covered or covered.
  • Non-woven textiles so-called nonwovens, usually have a high structural elongation and good deformability, which can be improved even further by using undrawn staple fibers or filaments, such as in DE-OS 30 29 752 for the manufacture of technical filters or DE-AS 15 60 797 for the production of imitation leather is described.
  • the nonwovens generally have a uniformly less structured exterior. Textile structures can practically only be indicated by appropriate coloring or embossing.
  • DD-PS 125 918 discloses a process for the production of textile fabrics, in which pre-oriented, undrawn yarns are processed into a fabric by weaving, knitting or knitting and then subjected to a thermomechanical treatment in the fabric.
  • thermofixing of pre-oriented, undrawn filaments has already been described.
  • DE-OS 28 21 243 describes the production of weft yarns which are intended to protect the belt yarns required in tire manufacture from uneven displacements.
  • special emphasis is placed on reducing free shrinkage at high temperatures, such as those that occur when tires are vulcanized.
  • the suitability of such threads or yarns for textile purposes and in particular the production of textured yarns cannot be found in this preliminary literature.
  • a mouldable, flat textile fiber material which consists of a base part or rear part, which mainly consists of a fiber with a low softening point and / or a highly stretchable fiber, and a pole part or surface part, the mainly consists of a fiber with a high softening point.
  • This material preferably has a laminate structure (page 8, line 12/13), the fiber materials being clearly separated from the base and pole part (page 8, line 21).
  • the fiber with a low softening point and high stretchability is said to be a highly orientable polyamide or polyester fiber with a birefringence of 0.02 to 0.08 or 0.02 to 0.045, which has an elongation at break of 100 to 500%.
  • the printing step gives no indication of the use of a yarn which has the combination of properties mentioned in claim 1, in particular the relatively high yield stress, and which is produced under tension by heat treatment following spinning.
  • this object was achieved by yarns which contain pre-oriented but undrawn textured polyester filaments and have a number of properties as set out in claim 1.
  • Preferred embodiments of such yarns or yarn components are the subject of the dependent claims, which are also directed to a yarn.
  • the production of such yarns is possible in accordance with the main process claim by texturing while largely avoiding simultaneous drawing and temperature treatment of the yarns under tension.
  • the following method claims are directed as sub-claims to preferred embodiments of the method according to the invention.
  • irreversibly highly deformable textile fabrics can be produced by weaving, knitting or knitting.
  • "Irreversibly highly deformable” is to be understood here as the property of the textile fabric, in the case of deformation, e.g. to give in to the applied load during deep-drawing and then to remain largely irreversible in the spatial shape desired by the deformation and not, as would be the case with an elastic textile fabric, to spring back into the original flat shape of the textile fabric due to the restoring forces acting on it.
  • the degree of three-dimensional deformability of a textile fabric depends on a large number of influencing variables, and it is therefore difficult to define it by specifying certain dimensions.
  • the radius of curvature, the depth of the deformation and the material thickness of the textile material have an influence on the deformability.
  • Other influencing variables are, for example the slidability of the material to be deformed, the type of manufacture of the flat structure, the thread titer, the thread thickness, etc.
  • "Highly deformable" is therefore to be understood in the present document as a deformability which is at least so great that the interior linings of passenger cars with such textile flat structures can be covered. When it comes to the interior paneling, the door panels and the interior paneling of the roof are particularly important.
  • the yarns required for the production of such textile fabrics are to be produced from textured yarns.
  • the low degree of elasticity can be achieved by the yarn according to the present invention. This is usually not the case if the yarn consists of highly elastic, false-wire textured filaments.
  • a particularly suitable method is, for example, the blowing nozzle texturing, in which even bulky yarns with low crimp elongation can be produced.
  • the object of the invention is achieved by yarns which at least partially consist of pre-oriented, undrawn synthetic filaments. These filaments should have an elongation at break of at least 70%, in particular 70-200% and a yield stress of at least 6 cN / tex. In preferred embodiments, the elongation at break of these filaments should be between 80 and 160%.
  • the yield stress of these polyester filaments should preferably be at least 7 cN / tex.
  • Yield tension is the yarn tension (tensile force divided by initial titer) at which the force-elongation curve deviates from the initially linear course, that is, a change in length of the threads becomes irreversible. The exact beginning of the irreversible change in length is often difficult to see. Instead, the minimum of the force-strain curve can be used as the value for the flow force. Such a minimum is usually observed after the linear rise and a certain overshoot in the floating point as a horizontal branch of the curve. In this area there is an increase in length without increasing the force. If the filamante is highly pre-oriented, this minimum can only be recognized as a turning point or as a kink in the curve. A determination of the yield stress is possible in any case. For example, if there is only a slight kink in the force-elongation curve, it will be possible to apply tangents to the different sections of the curve. The intersection of the tangents can then be viewed as the yield stress of this filament.
  • Preoriented, undrawn filaments made of polyester are usually produced by rapid spinning.
  • the degree of pre-orientation can be characterized by specifying the birefringence.
  • the birefringence of the filaments should be at least 27 ⁇ 10 ⁇ 3, preferably even at least 30 ⁇ 10 ⁇ 3.
  • These fast-spun threads should preferably not have been additionally subjected to drawing.
  • drawing should also not be associated with the texturing process of the threads. It is essential that the fast-spun, pre-oriented and undrawn threads retain their properties, that is to say, for example, also have a correspondingly high elongation at break, as stated above.
  • the required yield stress of at least more than 6 cN / tex is not achieved by commercially available pre-oriented, undrawn yarns.
  • the yield stress of these threads is significantly below the required limit.
  • the filaments required according to the invention can therefore not be obtained by the usual rapid spinning alone. In addition to rapid spinning, a temperature treatment under tension must be carried out, which leads to an increase in the yield stress, but on the other hand, the elongation at break resulting from rapid spinning can remain essentially unchanged.
  • yarns according to the invention have the advantageous property that they can be processed by weaving, knitting or knitting, without the risk of uneven drawing.
  • pre-oriented but still undrawn threads made of polyester are more dyeable than fully drawn filaments.
  • Such threads are processed directly into textile fabrics, however, there are short-term and sectionally high loads which lead to partial re-stretching of the filaments and thus to different dyeability.
  • Such structures are also characterized, as already pointed out above in the task, in that they are already a one-time deformation process (e.g. deep drawing) can be irreversibly deformed within wide limits. Textile fabrics made from such yarns are therefore particularly suitable as a covering or cladding for strongly curved surfaces.
  • Another advantage of the yarns according to the invention is their heat resistance due to the thread-forming material used.
  • the yarns used consist entirely of the filaments with the properties described above, amounts down to 6%, for example, are sufficient, but quantitative ratios of 40-60% by weight of the total denier of the yarn to those formed according to the invention are preferred Filaments.
  • a prerequisite for such processing of yarn components that do not have the properties required according to the invention is that the pre-oriented, undrawn filaments made of polyester with the specified properties necessary for the invention constitute the load-bearing component in the yarn.
  • Blown textured yarns are particularly preferred in the present invention. These yarns can be produced for example by means of devices according to DE-OS 23 62 326 and 19 32 706. All filaments can be fed to the texturing nozzle with the same advance, which results in a one-component yarn. Instead of this, however, different leads can also be selected to produce loop effects, resulting in a yarn with a load-bearing and a non-load-bearing component.
  • the supporting component in this case is the filaments formed with the least advance. According to the invention, it is necessary that the pre-oriented, undrawn polyester filaments required according to the invention make up at least part of the load-bearing component. It will usually consist entirely of the filaments of the invention.
  • the load-bearing component consists of different parts, for example yarns or the like.
  • the supporting component consists at least in part of the polyester filaments according to the invention, provided that the polyester filaments according to the invention determine the behavior of the supporting component during the deformation. Under these conditions it is possible that the yarn can have the required low degree of elasticity of less than 50%.
  • the yarns designed according to the invention should only have a low degree of elasticity, which should in any case be less than 50, preferably less than 30%, under a load of 5 cNtex.
  • the degree of elasticity or the elastic expansion ratio is understood to be the quotient of the elastic expansion and the total expansion for a selected tensile force. In the present case, this tensile force should be 5 cN / tex.
  • the degree of elasticity can be determined using known examination methods. The values specified in this document were determined by measurements in accordance with DIN 53835, Part 4, but the tensile force was not only reduced again to the pretensioning force, but was again put under pretensioning force after the thread had been completely relieved and the residual elongation was then determined. This measure gives better reproducible values, since the play that is unavoidable in the measuring apparatus can be switched off. In the standard mentioned, the degree of elasticity is listed under the synonymous name "elongation ratio".
  • the structural component of a textured yarn does not have to consist entirely of the filaments with the properties according to the invention, provided that it is ensured that the shaping or determining part of this component consists of filaments with the properties to be required according to the invention.
  • Yarns with a modified cross-section, with different dyeability, etc. can also be used to create effects.
  • yarns from flame-retardant raw materials A possibly lower elongation of the non-load-bearing component can be completely compensated for by an appropriate advance of the yarn. If the lead was correspondingly higher, this component would be present in the form of a loop in the yarn and would only make a minor contribution to the physical properties of the overall yarn.
  • the yarns according to the invention it is necessary that at least one filament yarn made of pre-oriented, undrawn polyester filaments with birefringence of at least 27 ⁇ 10 ⁇ 3 and elongation at break of 70-200% under both a texturing and a heat treatment at 100-180 ° C under tension be subjected. If several yarn components are processed together, it must be ensured that the polyester filament yarn with the properties required according to the invention results in the load-bearing component and is therefore processed with the least advance.
  • Preferred temperature ranges of the heat treatment are within the range of 100-180 ° C, in particular 120-150 ° C. Particularly good results were obtained at around 130 ° C.
  • the heat treatment of the yarns can be carried out, for example, with steam or in hot air.
  • the heat treatment of the yarns wound on packages is carried out in an autoclave using steam. Such steaming processes can be combined, for example, with the coloring of the textured M yarn.
  • the heat treatment of the yarn can also be carried out continuously, e.g. by means of a device as shown in U.S. Patent 4,316,370. It should be pointed out here that the heat treatment of the filaments can be carried out before or after a texturing process.
  • the choice of pre-orientation of the polyester filaments according to the invention i.e. essentially the winding speed in the rapid spinning process as well as the temperatures of the heat treatment of the fixing process have to be adapted to the respective requirements of the yarn according to the invention. Since, for example, the forces occurring during weaving usually do not increase linearly with the yarn titer, the processing properties can also be adapted to the requirements of further processing by selecting the yarn titer and the percentage distribution between load-bearing and non-load-bearing (e.g. enveloping) components.
  • Yarns with a relatively low pre-orientation also show an increase in yield stress after heat treatment, but this is associated with a noticeable decrease and a strong spread of tensile strength and elongation at break values.
  • any increase in the pre-orientation due to ever higher winding speeds of the threads is also not sensible.
  • As the winding speed increases not only does pre-orientation occur during rapid spinning, but crystallization already occurs. As a result, it is no longer possible to produce the desired low degree of elasticity in such yarns.
  • this means that textile fabrics made from such yarns can no longer be irreversibly deformed to a sufficient extent. Instead, a reversible, elastic deformability occurs to an increasing extent, which leads to processing difficulties when deep-drawing such textile fabrics.
  • Example 2 In contrast to Example 1, in which smooth, non-textured yarns were only examined as preliminary tests, in This example and in all subsequent examples produced textured yarns according to the invention. This was done with the help of an air nozzle texturing device as described for example in DE-OS 23 62 326. At least two yarns with different lead lengths were always air-jet textured, ie yarns were produced which had a load-bearing component and a non-load-bearing yarn component. Only yarns made from polyethylene terephthalate filaments were used in the present experiment. Two fast-spun but undrawn polyester threads with a titer of dtex 330 f 64, which show a birefringence of 35 ⁇ 10 ⁇ 3, served as the load-bearing yarn component.
  • the non-load-bearing component consisted of fully stretched thread material, namely two threads of titer dtex 167 f 64 and another thread of titer dtex 167 f 32. These three threads were fed to the texturing machine with a lead of 46%.
  • a textured yarn was made according to the state of the art.
  • the non-load-bearing yarn component was identical to the material described above, but the load-bearing component consisted of commercially available, stretched threads, namely two threads of titer 167 f 64 were used. These threads were jointly textured with leads of 10 and 46%, respectively, as described above.
  • the blended yarns according to the invention were subjected to a further heat treatment after texturing, namely they were wound on cross-wound bobbins and fixed in an autoclave with steam at 130 ° C. for 10 minutes.
  • Example 2 was repeated with two fast spun polyester yarns as the load-bearing component.
  • the single filaments had a birefringence of 35 ⁇ 10 ⁇ 3, these yarns were submitted to the air nozzle texturing machine with a lead of 8%.
  • Three yarns also made from polyethylene terephthalate threads served as fancy yarn, but were stretched and each had a titer of dtex 150 f 64. These were drawn yarns false wire textured. In contrast to the smooth delivery yarns for the load-bearing component.
  • This information and the textile values for tensile strength, elongation at break and yield stress obtained before and after the heat treatment according to the invention are recorded in the table below.
  • the designation "V" in the birefringence column indicates that these yarn components are drawn and textured with false wires.
  • Example 3 was repeated, the threads for the load-bearing component being varied. The results are tabulated below.
  • the degree of elasticity was determined before and after heat treatment at a load of 5 cN / tex in run c of Example 5. It was 15% before the heat treatment and 33% after this treatment.
  • the textile values in the table were always based on the total titer, i.e. that the titer contribution of the non-bearing component was also taken into account.
  • the non-load-bearing component can also make a certain contribution to the textile values of the overall yarn. This applies in particular to the runs in which the advance of the effect component did not differ too much from the supply of the yarns for the load-bearing component. While the tensile strength is influenced by it relatively little, the influence on the elongation at break is very clear. With increasing advance of the fancy yarn, i.e. the non-load-bearing component, the elongation at break increases significantly.
  • the heat treatment was also varied in this example.
