Abstract
Description
Technical field
[0001] The present invention lies in the field of garment manufacturing and relates to a basic textile product. Background and state of the art
[0002] The prior art reveals garments where the quality of the materials and manufacturing processes is not sufficiently guaranteed. Customers expect consistent quality, particularly with basic textile products—garments offered over several seasons or even years. For basic textile products sewn together from multiple pieces, such as T-shirts, trousers, or underwear, the seams that hold these pieces together must meet especially high quality standards. The use of inadequate materials or seams results in garments that, especially after repeated wear, exhibit early defects such as seam tears, holes, or loose threads.These early-onset defects lead, on the one hand, to less sustainable production and, on the other hand, create a negative consumer experience for the customer.
[0003] One object of the invention is therefore to provide a basic textile product in which a particularly high quality standard can be ensured over several years.
[0004] This problem is solved by the subject matter of the independent claim. Further advantageous embodiments are described in the dependent claims and the overall disclosure.
[0005] The disclosed textile baseline product is manufactured by means of the following steps: cutting out a section from a textile fabric, wherein a remaining part of the textile fabric forms a production piece, and clamping the section into a device with two rod elements positioned opposite each other at an adjustable distance, wherein the section has a seam with a thread as well as a first end and a second end opposite the first end, wherein the section is arranged on the two rod elements by attaching one end of the section to each of the two rod elements.
[0006] In some embodiments, the cutting out of the section can be done either manually and / or using a cutting tool such as a blade or a laser beam, whereby the term "cutting out" can also be understood as cutting or separating a section. Even after cutting, it is advantageously possible to infer the material properties and quality of the finished product from those of the section. Within the scope of this disclosure, the section can also serve as an example for a batch of sections of the same type. The section can then, for example, also be designed as a cladding element, whereby the properties of one cladding element can be used to infer the properties of all cladding elements comprising the batch.
[0007] In some embodiments, the clamping of the section into the device can be done manually or mechanically.
[0008] In some embodiments, the section can exhibit transversely elastic or bi-elastic properties. In this context, "transversely elastic" refers to a section that is elastically stretchable only in one direction, namely perpendicular to its length. This stretching typically occurs in a weft direction for woven fabrics or laterally for knitted fabrics, while the longitudinal direction remains largely dimensionally stable. The transversely elastic section can thus exhibit limited and controlled flexibility. The term "elastic" means that a material, after deformation by the application of force, returns to its original shape once the force is removed.
[0009] A component with bi-elastic properties can be elastically stretched in both the longitudinal and transverse directions. A garment or basic textile product made of a bi-elastic material can therefore adapt to mechanical stresses in two directions and generally exhibits higher elasticity and resilience than a component primarily made of a transversely elastic material. In principle, the properties of a single component can be used to infer the properties of a garment, and especially the properties of a basic textile product.
[0010] The section is cut from a textile fabric. For the purposes of the disclosure, the term "textile fabric" refers to a flat, sheet-like structure that is previously manufactured from textile raw materials and has a greater extent in the length and width directions compared to its thickness. The textile fabric consists of fibers, filaments, yarns, and / or thread systems that may be bonded together. The textile fabric may, for example, be a roll of fabric or ribbons. It may be pre-treated, for example, by weaving, knitting, braiding, felting, laying, non-woven fabric production, or spunbond fabric production, as well as a combination of these treatments.
[0011] The textile surface product can be formed in one piece or in multiple layers in some embodiments and can have homogeneous or inhomogeneous structures. It can be flexible, elastic, or have limited dimensional stability and can include both open-pored and closed-pore surface structures. Furthermore, the textile surface product can be coated, laminated, impregnated, or functionally finished, for example, with polymeric, elastomeric, or thermosetting materials, without thereby losing its textile character. The term "textile surface product" includes, in particular, but not exclusively, woven fabrics, knitted fabrics, nonwovens, composite textiles, technical textiles, and textile semi-finished products for further processing into garments.
[0012] Preferably, the section is cut out such that it has a length in the range of 100 mm to 500 mm and optionally a width in the range of at least 4 mm, in particular between 4 mm and 250 mm. This allows the section to be processed particularly advantageously in subsequent steps.
[0013] After cutting, the remaining piece is the original product. The original product is the uncut portion of the textile surface element. Since both the original product and the cut-out piece originate from the same textile surface product, they advantageously have a similar, preferably identical, material composition and quality, particularly in terms of durability.
[0014] The section can be clamped into the device. The two rod elements can, for example, be made of a metallic material.
[0015] The clamped section has a seam. For the purposes of this disclosure, the term "seam" refers to a linear or planar zone formed along a predetermined seam line, created by means of a thread and by pricking with a sewing needle into a textile element, such as the section. The seam can be formed by joining textiles, for example, by sewing, particularly using a sewing machine. At least one thread can be used when sewing the seam, and different stitch types such as lockstitch, chain stitch, blind hem stitch, or combined multi-thread stitches can be employed.
[0016] In some embodiments, the seam of the section can be sewn into the textile product before cutting, or it can already be present when the textile product is provided. The latter means, for example, that a textile product with a seam can first be provided, and then a section with the seam can be cut from the provided textile product.
[0017] It is also possible to first cut out the section and then seam it, for example by sewing the seam or by stitching two ends of the section together to form the seam. Alternatively, two sections can be cut out and then joined by a seam to form a single section, which is then subjected to mechanical stress. Preferably, a section can be cut out that has two ends. These ends can be sewn together, for example, so that the section is closed all around or forms a round or circular shape.
[0018] Since the test checks whether fiber fragments protrude from the seam area after mechanical stress, it is not absolutely necessary to join two separate sections together. A seam weakens the textile element, and experience shows that initial defects, such as protruding fiber fragments, often occur in the seam area.
[0019] Preferably, the seam is an overlock seam, or is an overlock seam, in particular a single-needle overlock seam. An overlock seam can be a seam that sews two pieces of fabric together in an overlock stitch with more than two single threads. The seam can be machine-made. Preferably, the seam has a stitch ratio of between 4 and 8 stitches per centimeter, preferably 12 stitches per 2 cm.
[0020] A single-needle overlock seam can be an elastic, finishing, and joining seam created with an overlock sewing machine using one needle and one or two looper threads. In this context, the seam can run directly along a cut edge, forming a flat, flexible seam structure with good stretch. Due to its elasticity, the single-needle overlock seam is particularly suitable for knitwear, active fabrics, and elastic materials. Such a single-needle overlock seam is therefore especially well-suited for carrying out the individual steps.
[0021] Preferably, the seam includes, or is itself a closing seam. The closing seam can serve to permanently join two open fabric edges, creating a closed piece or garment. For example, it can join the two end sections of the cut-out piece, or it can join two or more layers of fabric along their edges, with the edges either lying against each other or overlapping. The sewing creates a mechanically strong connection that can preferably withstand tensile, tearing, and, if applicable, stretching forces.
[0022] The seam may be provided to have at least one thread with a thread number between Nm 50 and Nm 500 (Nm = number metric), preferably Nm 150. Within the scope of the disclosure, the thread number denotes the fineness or thickness of the thread and describes the length per unit mass of the thread. For example, a 100 m long thread with a thread number of 100 Nm weighs 1 g.
[0023] Preferably, the seam comprises at least one thread made of a continuous polyester filament. This continuous polyester filament thread has a uniform thickness, high tensile strength, and a smooth surface. Since virtually no fiber ends protrude from the thread, it is comparatively lint-free, abrasion-resistant, and particularly durable.
[0024] Furthermore, the textile baseline product is manufactured by mechanically stressing the section using the device by alternately increasing and decreasing the distance between the two rod elements, whereby the section, and in particular the seam, is alternately stretched and relaxed. This repeated and alternating stretching and relaxation of the section, and especially the seam, is representative of realistic wear of the same section or seam, which were later processed into a textile baseline product made from the same textile fabric.
[0025] The stretching and relaxation are achieved through the changing distance between the two bar elements. Since the section is clamped between the two bar elements, a comparatively large tensile load is realized, for example, when the distance between the two bar elements is greater than at an initial average distance between the two bar elements, or rather, between the ends of the section.
[0026] In embodiments where the section is completely closed or forms a circular shape, the distance between the two rod elements can be increased in such a way that the circumference of the section is increased by 40% to 90%, in particular 45% to 85%.
[0027] Preferably, mechanical loading can be applied in the transverse direction to a transversely elastic section and in both the transverse and longitudinal directions to a bi-elastic section. This allows for advantageous insights to be gained regarding the quality of sections with different material properties.
[0028] The mechanical loading may include: stretching the section with a tensile force in a range between 100 N and 2000 N; relaxing the section, thereby relieving several of the threads of the seam, with the previous stretching and compression steps being repeated at least 500 times, preferably at least 3000 times.
[0029] In this context, materials such as lightweight cotton or elastane (e.g. polyurethane) can be subjected to mechanical stress with a tensile force in the range of 200 N to 500 N, medium-weight woven fabrics with a tensile force in the range of 300 N to 1000 N, materials for heavy outdoor fabrics, jeans or functional materials with a tensile force in the range of 700 N to 1600 N and elastic materials with a tensile force in the range of 100 N to 700 N.
[0030] After mechanical loading, the section is evaluated as a good part if, after the mechanical loading step, fewer than four fiber fragments protrude from the section, particularly in the area of the seam or from the seam itself. It is evaluated as a defective part if, after the mechanical loading step, more than three fiber fragments protrude from the section, particularly in the area of the seam or from the seam itself. It is understood that the protruding fiber fragments are those that did not protrude from the section before mechanical loading, but rather those that protrude as a result of the mechanical loading. The term "fiber fragment" describes a textile fiber, or a piece thereof. This can be a filament, a thread, a yarn, a fiber, or a part thereof. A fiber fragment can be part of the section or part of the thread of the seam.The assessment can be carried out by a person, for example through inspection, or by machine, especially by a camera.
[0031] In this context, a component rated as good exhibits improved quality, particularly greater durability, compared to a component rated as bad. This evaluation step allows for the advantageous sorting out of bad components, thereby increasing the overall quality of the processed production pieces. The textile baseline product is thus designed to be particularly sustainable. Further criteria can also be incorporated into the evaluation of a component as good, as disclosed in the disclosure. The textile baseline product according to the invention is therefore essentially manufactured not only through the production steps described above, but also through testing and evaluation steps. The interaction of manufacturing, testing, and evaluation ensures efficient and sustainable production with consistently high, measurable quality of the textile baseline products over several years.This ensures that the customer's need for consistent quality is met even over several years and with potentially changing suppliers. This is particularly relevant for core product lines, unlike seasonal products, in order to retain existing customers in the long term and meet their expectations.
[0032] To ensure that the assessment of the component as a good part is particularly reliable, it may be necessary to perform a second mechanical load on the same component after an initial mechanical load test and the first assessment. In other words, the same component is mechanically loaded twice in succession.
[0033] Alternatively, a second, identical section—that is, a section with the same properties as the first, but not the same section—can be subjected to mechanical stress again. This second, identical section could, for example, be another section cut from the same textile fabric as the first. By repeatedly subjecting the same or identical section to mechanical stress, relatively reliable results regarding its mechanical strength can be obtained.
[0034] Following the evaluation, the production piece is processed into a garment blank if the component was rated as a good part, whereby the garment blank exhibits the material properties, particularly durability, of a component rated as a good part. Because only production pieces with the material properties of a good part are processed, the quality of the garment blank is comparatively very high. This processing can include further textile processing steps, such as joining the production piece with other parts or reshaping the production piece, for example, through another cutting step.
[0035] In this process, the production piece, which may be in the form of a cut piece, roll of fabric, pre-formed textile, or textile composite element, can be processed along predefined contours, fold lines, or joining areas. The processing includes, in particular, cutting, punching, or separating the production piece into defined sections, as well as arranging, folding, or draping these sections according to a planned garment geometry. Furthermore, the processing step can include joining selected edge and connection areas of the production piece by textile joining methods, in particular by sewing, gluing, welding, laminating, or a combination thereof, so that a garment blank is created that already exhibits functional and structural characteristics of the subsequent basic textile product. Seams, joining, or transition zones can be single- or multi-layered.
[0036] It may also be necessary to further shape the garment, for example by sewing, pleating, gathering, or shaping seams, to give it its final fit. Subsequently, or alternatively, functional elements can be added, such as sewing in sleeves, collars, cuffs, or pockets, as well as inserting fasteners like zippers, buttons, snaps, or hook-and-loop fasteners.
[0037] A further processing step can involve edge and finishing. This includes finishing the hems on sleeves, trouser legs, or the bottom edge of the garment, for example by folding and hemming, binding with tape, or using cuffs. At the same time, reinforcements can be added, for example, through interlinings, reinforcing seams, or additional layers of material in high-stress areas.
[0038] Furthermore, the finished product can be surface-finished, for example by ironing, steaming, or heat-setting to stabilize the shape. Decorative or marking steps are also possible, such as applying embroidery, printing, appliqués, labels, or care instructions.
[0039] Processing can also be understood as the targeted shaping, joining, and assembly of the production piece from a textile fabric into a semi-finished product that is at least partially three-dimensional and defines the basic form of a subsequent textile baseline product. It is understood that the textile baseline product is a garment. This can be obtained, for example, from a garment blank described here. The term "baseline" refers to a product that is not produced seasonally but rather consistently over several years.
[0040] The disclosure may also stipulate that at least one processing step takes place before the mechanical stressing step.
[0041] The garment blank created through processing can define the essential contours, volumes, and functional areas of the basic textile product, but may not yet have any or only partial finishing steps. In particular, finishing work such as attaching closures, hems, cuffs, decorative elements, or surface treatments can be reserved for a subsequent manufacturing step. Of course, it is also possible that the production piece already essentially represents a garment blank.
[0042] Following the processing step, an identification element is attached to the garment blank to identify and name the clothing line, thus enabling the production of a basic textile product. An identification element is a physical and / or digital element designed to uniquely assign a basic textile product, or multiple basic textile products, to a specific clothing line, thereby identifying and naming it. The identification element thus serves for the visual, machine-readable, and / or information technology-based identification of the clothing line. The clothing line name can include, for example, the specific name of the clothing line, such as "Basics," "Basic," "Basis," or similar.
[0043] The identification element can be permanently or detachably attached to the garment blank and is preferably located in a designated area. It can be an integral part of the textile material or designed as a separate component.
[0044] The identification element can be implemented in various forms, including labels, tags, prints, embroidery, woven marks, appliqués, tags, or as a structure integrated into the textile material. Alternatively or additionally, the identification element can include an electronic or digital component, such as an RFID chip, an NFC transponder, a QR code, or a comparable machine-readable information carrier. To identify and name the clothing line, the identification element can contain alphanumeric characters, graphic symbols, logos, color codes, or digital data sets that uniquely identify the clothing line. The identification element can also carry additional information, such as size, material, place of manufacture, production batch, or care instructions, without losing its function as an identification element.
[0045] The identification element for labelling and naming the clothing line thus includes all embodiments that enable a unique assignment of a basic textile product to a defined clothing line, regardless of the specific physical or digital design of the identification element.
[0046] The textile baseline product described in the disclosure offers the advantage of being manufactured in a particularly sustainable manner, since the garment blank used for it possesses the material properties of a high-quality component and is therefore especially durable. Furthermore, the selection of high-quality and low-quality components reduces the use of inferior textile surface products. This allows for the production of particularly high-quality textile baseline products.
[0047] Preferably, the sample is washed before clamping at a temperature between 40°C and 80°C, preferably between 55°C and 65°C, for a duration of between 40 and 80 minutes, preferably between 55 and 65 minutes. Washing simulates realistic stress on the sample with regard to moisture and dynamic movements in a washing drum, so that the steps after clamping, in particular the mechanical loading, take place under more realistic conditions. It may be provided that a fabric softener is used during the washing process. This also simulates the chemical stress on the sample caused by a fabric softener, so that conclusions can be drawn from the subsequent mechanical loading regarding the resistance of a sample treated with fabric softener, or of a corresponding basic textile product.
[0048] The device may be provided with: a longitudinal section projecting from each rod element; a coupling element arranged between and connected to the two longitudinal sections; a power transmission element arranged on the coupling element; and a turntable, wherein the turntable is set into rotation by means of a drive unit and is connected to the power transmission element. The rotation of the turntable can be converted into a cyclic linear motion of the coupling element by means of the power transmission element, and the distance between the opposing rod elements can be cyclically varied.
[0049] The interaction of the described components allows the distance between the two rod elements to be changed via a rotating turntable. The faster the turntable is driven by the drive unit, the faster the rod elements move towards or away from each other. With each full rotation of the turntable, the two rod elements move once from their respective starting points to one endpoint and back again. In other words, one full rotation of the turntable corresponds to a complete forward and return travel path for each rod element.
[0050] The power transmission means and the coupling element are moved in a first direction by the turntable, while the two rod elements are moved in a second direction via the movably mounted longitudinal parts, which is approximately orthogonal to the first direction.
[0051] The device allows for a particularly uniform and reproducible application of mechanical stress to the workpiece. This makes it possible to compare the quality of different workpieces.
[0052] In some embodiments, the device may also include additional components that cause additional mechanical stress on the section, for example, a torsional load.
[0053] For improved guidance, the two rod elements can each be mounted on a slide, which in turn can be moved along a guide element in the second direction. The guide element can, for example, be designed as a rail.
[0054] Since the section is attached to the two rod elements by securing one end of the section to each of the two rod elements, the section is subjected to loading and unloading by the moving rod elements as the turntable rotates. The faster the turntable rotates, the greater the load on the section.
[0055] Preferably, the rotary disc rotates at a speed in the range of 10 rpm to 2000 rpm. This corresponds to 10 to 2000 load cycles of the component. Particularly preferably, the component is loaded at 50 cycles per minute.
[0056] In summary, the manufactured basic textile product exhibits a particularly high material and / or processing quality and is produced in a particularly sustainable manner.
[0057] Aspects of the invention are explained in more detail with reference to the exemplary embodiments shown in the following figures and the accompanying description. The figures show: Fig. 1a a textile surface product with a production piece and a sub-piece; Fig. 1b a clamped section; Fig. 1c a portion assessed as good; Fig. 1d a section rated as defective; Fig. 1e a garment blank; Fig. 2a Schematic top view of the device with a clamped section which is loaded via a first distance between the two rod elements; Fig. 2b Schematic top view of the device with a clamped section which is loaded via a second distance between the two rod elements; Fig. 3 Schematic side view of the device.
[0058] Fig. Figure 1a shows a textile fabric 20 from which a section 10 is cut out. The uncut portion of the textile fabric 20 forms a production piece 30. Section 10 and production piece 30 thus share the same base textile. This allows for advantageous inferences to be made about the properties of production piece 30 based on the properties of section 10. The left and right edges of the cut-out section 10 can be joined by a seam, forming a completely closed section 10. To illustrate this, the left and right edges of the cut-out section 10 are shown with schematically indicated fraying.
[0059] Fig. Figure 1b shows the cut-out section 10 with a seam 11, which is attached to two rod elements 41 of a device. In the shown section 10, some areas of the thread 12 are located on the top side of the section 10 and are therefore visible to an observer in the top view shown. Other areas of the thread 12, however, are located on the underside of the section 10 and are therefore not visible to the observer in the top view. In this case, a first end 13 and a second end 14 of the section 10 are each clamped to one of the two rod elements 41 opposite each other. In the clamped state, the section 10 can be mechanically stretched and relaxed alternately by changing a distance x between the two rod elements 41. In other words, the section 10 is stretched, which in particular puts stress on the seam 11.
[0060] Fig. Figure 1c shows a section 10 that was rated as good because only two fiber fragments 121 protrude from the seam 11. The thread 12 continues to form the seam 11, so that even after mechanical stress, the section 10 can be considered free of defects. A section 10 rated as good therefore has a particularly high-quality seam 11.
[0061] Unlike most in Fig. 1c shows Fig. 1d A section 10 assessed as defective. This is characterized by four fiber pieces 121 protruding from the seam 11. In addition, another fiber piece 121 protrudes from section 10. This is also taken into account in the assessment.
[0062] In Fig. Figure 1e shows a garment blank 50, which was produced from a processed production piece 30, wherein the production piece 30 has material properties of a component 10 rated as good. Since the quality of the production piece 30 can be inferred from the quality of the component 10 rated as good, the garment blank 50 accordingly exhibits the quality of a component 10 rated as good. The garment blank 50 is therefore of particularly high quality. To indicate this, an identification element 60 for marking and naming the clothing line is attached to the garment blank 50. By attaching the identification element 60, a basic textile line product 1 is produced from the garment blank 50.
[0063] Fig. Figure 2a shows a device 40 suitable for cyclically stretching and relaxing the section 10. For this purpose, the section 10 is connected at each end 13, 14 to a rod element 41 and is thus clamped between the two rod elements 41. The mechanical load is applied by changing the distance between the two rod elements in the x-direction, or by changing the distance between the two ends 13, 14 of the section 10. This change in distance is achieved by moving the two projecting longitudinal sections 42. These are each connected at one end by a hinge to a coupling element 43. By moving the coupling element 43 in the y-direction, the rod elements 41 move accordingly in the x-direction. To enable improved guidance of the rod elements 41 and the coupling element 43, they are guided by a guide 47.The respective travel paths of rod element 41 and coupling element 43 are therefore particularly precise.
[0064] To enable the coupling element 43 to move in the y-direction, it is connected to a rotary disk 45 via a power transmission means 44. The rotary disk 45 is driven by a drive unit, thus allowing cyclical movement of the coupling element 43. The faster the rotary disk 45 is driven, the faster the section 10 is loaded. In the Fig. In the position shown in Figure 2a, the coupling element 43 is located at a lower stop in the y-direction. The section 10 is therefore stretched or relieved minimally or not at all.
[0065] In contrast, in Fig. 2b The coupling element 43 is held against an upper stop in the y-direction, and the section 10 is stretched accordingly. This is further illustrated by a narrower shape of the clamped section 10. A rotation of the rotary disk 45 by 360° thus results in a complete stretching and relaxation cycle of the section 10.
[0066] Fig. Figure 3 shows a schematic side view of the device 40, from which it can be seen that the drive unit 46 is arranged below the turntable 45. The transmission of torque from the drive unit 46 to the turntable 45 is thus particularly efficient. Likewise, the guide element 47 is arranged below the coupling element 43 and the rod elements 41. This underside arrangement makes it particularly easy for a user to access the rod elements 41 or the clamped section 10 from above. The section 10 is in Fig. Section 10 is clamped centrally between the rod elements 41. Depending on the arrangement of section 10 in the z-direction, the type of mechanical load can be further influenced. Due to their length, the rod elements 41 oscillate, especially under comparatively high cyclic loads, for example, under loads exceeding 50 cycles per minute. The closer section 10 is clamped to the free ends of the rod elements 41, the more intense the vibrations act upon it. Therefore, changing its position in the z-direction can further influence the type of mechanical load.
[0067] The in the Fig. 2 to Fig.The device 40 shown in Figure 3 is particularly advantageous for mechanically stressing the section 10, which can thus be easily evaluated as a good or bad part. By using the device 40, the quality of the section or the textile baseline product can be ensured particularly easily.
