Description

Technical Field

[0001] This utility model relates to a textile product that can be automatically or semi-automatically disassembled and / or recycled. Background Technology

[0002] The textile industry is the world's second most polluting industry. Today, a truckload of textiles is discarded every second. Only 1% of the materials used in the textile industry are recycled, resulting in a loss of up to $50 billion worth of unused materials annually. These problems, while less severe, are also relevant to the furniture industry and other textile-based sectors, including clothing, footwear, furniture, flooring, mattresses, bedding, and automotive parts such as airbags, seat covers, and seat belts.

[0003] Most multi-part textile products are not reusable at the end of their lifespan, or are extremely difficult to recycle into usable items. Waste textiles typically end up in incinerators or landfills. If they are recycled, they are usually shredded into small pieces. In the best-case scenario, different materials are then separated according to their type using air pressure and centrifugal force. This energy-intensive and complex process results in a decrease in the quality and economic value of the recycled materials.

[0004] Because recycled materials are of much lower quality than virgin materials, they cannot be reused in the same industry or application. Recycled textiles and leather are primarily used in insulation pads, dust collector cloths, and mobile fabrics, and as fillers in concrete and polymer production. This form of recycling is often referred to as "degraded recycling."

[0005] Both chemical and mechanical recycling processes face the challenge of hard parts (such as zippers and buttons). Hard parts can cause mechanical blockages and damage during both mechanical recycling (i.e., fibrillation) and chemical recycling (i.e., depolymerization and repolymerization processes, such as Econyl, or viscose processes, such as Saxcell Refibra and Renewcell). Furthermore, both recycling processes require high-purity raw materials for their processes, necessitating the separation of non-recyclable fabrics from recyclable fabrics. Therefore, both hard parts and non-recyclable parts must be removed before recycling begins. This process, known as “delissage” or disassembly, is currently carried out in two ways: manually or with stronger, coarser fiber-forming machines, such as the Exel and Jumbo shredders from Laroche / Andirtz. Unfortunately, manual removal of hard parts is economically impractical, and studies have shown that coarser fiber-forming machines require pre-sorting with exhaust and produce shorter (lower quality) fibers.

[0006] Furthermore, the energy consumption of these processes adds a significant dimension to their overall efficiency. Both manual dismantling and mechanical fiberization require substantial amounts of energy, but in different ways. Manual separation increases operation time, which indirectly translates into higher energy costs per unit of recycled material. In contrast, coarser shredders may be faster and more automated, but require significant power to process mixed material streams, especially when harder or denser components are present. This trade-off between energy use and the quality of the resulting fibers highlights a key dilemma within current recycling technologies: balancing sustainability goals with economic and practical feasibility.

[0007] There is clearly a need for an effective and (semi-)automatic method to separate or disassemble the various components of textiles during the recycling process, a method that can prevent material contamination, easily remove hard parts, and improve the efficiency and quality of existing recycling processes. Utility Model Content

[0008] This utility model relates to a textile article that can be automatically or semi-automatically disassembled and / or recycled. The textile article includes at least a first part and a second part, wherein the first part and the second part are connected by a connecting device. The first part is a recyclable material composed of at least 50 wt.% of a material selected from the group consisting of cotton, polyester, polyamide, aramid, cellulose material, wool, natural leather, synthetic leather, acrylic resin, or combinations thereof. The second part includes textile recycling interference selected from the group consisting of zippers, buttons, elastic bands, snaps, rivets, eyelets, hooks and loops, reflective tape, RFID or QR tags, labels, linings, beaded edges, sequins, rivets, foam padding, fastening bands, logos, non-recyclable mixtures, or combinations thereof. The connecting device comprises polymer melt yarn with a melting temperature between 60°C and 220°C, wherein the amount of the connecting device is between 0.1 wt.% and 5 wt.% based on the total weight of the textile product, and wherein the first and second portions are separable from each other by melting the polymer melt yarn. The environmental impact of the textile industry is significant, as it is the second most polluting industry in the world. This invention addresses this problem by drastically reducing the amount of discarded, non-recyclable, or non-reusable textile products. This simplifies the removal of interfering items such as buttons, zippers, and elastic bands, ensuring the recyclability of multi-material and multi-layer garments and better preservation of mechanical properties during recycling. The product allows for easy disassembly of multi-part textile products at the end of their service life, preventing contamination by recyclable materials.

Further guidance, including definitions of terms used in the specification, is provided to better understand the teachings of this invention. The terms or definitions used herein are merely for the purpose of aiding in understanding this invention.

[0021] Throughout this specification, references to "an embodiment" or "an embodiment" mean that a particular feature, structure, or characteristic described in connection with that embodiment is included in at least one embodiment of the present invention. Therefore, the phrases "in one embodiment" or "in an embodiment" appearing throughout this specification do not necessarily refer to the same embodiment, but may refer to the same embodiment. As will be apparent to those skilled in the art based on this disclosure, particular features, structures, or characteristics can be combined in any suitable manner. Furthermore, while some embodiments described herein include some but not all of other features included in other embodiments, combinations of features from different embodiments are intended to be within the scope of the present invention and form different embodiments, as will be understood by those skilled in the art. For example, in the following claims, any claimed embodiment may be used in any combination.

[0022] The term "textile articles" or "textile-based articles" is used herein to refer to objects that are at least partially composed of textiles and / or leather (leather derived from animal hides or synthetic leather). Non-limiting examples of textile articles include clothing and footwear; safety clothing (e.g., cut-resistant gloves), safety garments, and bulletproof vests; household textiles such as cleaning cloths, mops, sheets, blankets, tea towels, towels, tablecloths, and headscarves; interior textiles including sheer curtains, drapes, carpets, floor coverings, furniture upholstery, and awnings; technical textiles such as waterproof canvas, tents, parachutes, screens, and ropes; geotextiles used for flood control, erosion control, and reinforcement of ground beneath roads; rubber reinforcements found in bicycle and automobile tires, conveyor belts, hoses, and rubber boats; and textile products used in vehicles (e.g., automobiles, trains, and airplanes), including airbags, seat covers, and seat belts.

[0023] Beyond these examples, the term "textile products" also encompasses accessories and bags, including a wide variety of everyday and specialized items. Accessories (such as scarves, shawls, belts, hats, gloves, and ties) are typically made of natural or synthetic textiles (such as cotton, wool, silk, polyester, or blends thereof) and are often combined with stiffer components (such as buckles, fasteners, and zippers, which present challenges during recycling). Similarly, bags, including handbags, backpacks, travel luggage, tote bags, and wallets, are typically composed of textile and leather materials paired with reinforcements such as metal frames, plastic bases, and synthetic linings. While these combinations provide durability and structural support, they complicate recycling due to the need to separate multiple material types.

[0024] In the context of this utility model, the terms "automatic" and "semi-automatic" refer to processes in which the removal of textiles is not done manually, but is performed entirely (automatically) or mostly (semi-automatically) by machines or devices.

[0025] The term "yarn" or "thread" refers to plied or filament yarns made from spun fibers; they are essentially looped and thus constitute yarn. In this document, a distinction is made between "standard yarn" and "melt yarn".

[0026] The term "standard yarn" includes both sewing thread and embroidery thread. It refers primarily to sewing thread, decorative thread (such as metallic or thicker yarn), and overlock thread optimized for overlock sewing machines, all used to join two parts together. "Standard yarn" generally refers to yarn well-known in the textile industry and commonly used in the production of textile products. Specifically, standard yarn is made from materials selected from the group consisting of cotton, linen, polyester, rayon, wool, nylon, silk, or combinations thereof. This type of yarn does not melt within the melting temperature range of molten yarn and therefore does not undergo any physical changes at temperatures within that range. Textured yarn is part of this definition.

[0027] The term "melting yarn" refers to yarn with a known melting point or melting temperature, which melts when heated to a temperature within that melting temperature range.

[0028] The term "sewing" refers to the process of working with needles and thread or forming something using needles or thread, such as attaching parts together with needles and thread. Sewing can be done manually or by machine. When a sewing machine is used, the term "stitching" is used. Therefore, "sewing" also includes machine stitching with needles and thread.

[0029] In a first aspect, this utility model relates to a textile article capable of being automatically or semi-automatically disassembled and / or recycled. The textile article comprises at least a first part and a second part, which are connected by a connecting device. The first part is a recyclable or reusable fabric composed of at least 50 wt.% of a material selected from the group consisting of cotton, polyester, polyamide, aramid, cellulose materials, wool, acrylic resin, natural leather, synthetic leather, natural rubber, synthetic rubber, or combinations thereof. The second part includes textile recycling interference selected from the group consisting of zippers, buttons, elastic bands, snaps, rivets, eyelets, hooks and loops, reflective tape, RFID or QR tags, labels, linings, beaded edges, sequins, rivets, foam padding, fastening bands, logos, non-recyclable mixtures, or combinations thereof. The connecting device comprises polymer melt yarn with a melting temperature between 60°C and 220°C, wherein the amount of the connecting device is between 0.1 wt.% and 5 wt.% based on the total weight of the textile product. Furthermore, the first and second portions are separable from each other by melting the polymer melt yarn. Textile interferences may be textiles incompatible with the first textile product.

[0030] Most textile products are made of different materials, each requiring a different recycling process. Contamination of one material by another leads to a decrease in the quality of the recycled textile material. By using polymer-melted yarns, the different materials present in textile products manufactured according to this invention can be non-destructively broken down into units composed of only one material. This ensures that the purity of the resulting recycled material is maintained. Therefore, these textile products can be easily, effectively, and qualitatively recycled after use, and the mechanical properties of the recycled material are better preserved.

[0031] Since the quality degradation of recycled materials from the textile industry is primarily due to decreased mechanical properties and reduced purity, this invention enables technicians to obtain high-quality recycled products from the textile industry. This invention can be introduced into the textile industry without requiring significant adjustments to production facilities. In fact, the melt-bonded yarn is suitable for existing sewing machines and provides a strong bond.

[0032] The built-in disassembly function of this invention is based on the use of polymer melt yarn to sew or stitch textile products during the manufacturing process. Various components and materials of the textile product can be disassembled by heating the yarn to a temperature within its melting point range. Preferably, the product or melt yarn is heated to a temperature equal to or higher than the yarn's melting point. The melting temperature of the polymer melt yarn is preferably between 110°C and 220°C, more preferably between 150°C and 210°C. When using melt yarn for sewing with industrial machines, the temperature of the melt yarn may rise due to friction. Therefore, a minimum melting temperature of 110°C will ensure that the yarn does not melt during production or during use. Additionally, the melting point of the polymer melt yarn should ideally be below 220°C, as synthetic textiles may also melt at temperatures above 220°C, which could lead to material loss or undesirable contamination of other materials, and cellulose materials may be affected at high temperatures.

[0033] In one embodiment, the textile includes 0.5 wt.% to 3 wt.% of connecting devices constituting the total weight of the textile article. This specific range is chosen to ensure that the connecting devices provide sufficient structural integrity while allowing for easy disassembly when the molten yarn is heated. The amount of connecting devices within this weight percentage range provides an optimal balance: it ensures the textile article remains durable during normal use, but still allows for effective disassembly at the end of the article's life when the connecting devices, made from the molten yarn, transition to a liquid or semi-liquid phase upon reaching a specified melting temperature. By keeping the connecting devices within this weight percentage, the overall mechanical properties and functionality of the textile article are preserved, while allowing for disassembly for recycling or reuse with minimal residual contamination from the yarn. This range is particularly suitable for applications where textile articles require durability but must also meet sustainability goals, as it allows for effective material separation and recycling.

[0034] According to one embodiment, based on the total weight of the polymer melt yarn, the polymer melt yarn consists of at least 90 wt.%, preferably at least 99 wt.% of the polymer. In another embodiment, the polymer melt yarn comprises polymers selected from the group consisting of polyolefins, polyesters, polyoxymethylene (POM), polypropylene, polyurethane, polyamide, polylactic acid, polyvinyl alcohol (PVA), copolymers thereof, or combinations thereof. The inventors of this invention have discovered that, using the above composition, automatic or semi-automatic disassembly functionality is maintained even when the melt yarn is partially composed of other materials.

[0035] Polyolefins are polymers composed solely of carbon and hydrogen; the most known examples are polyethylene (PE), polypropylene (PP), polybutene (PB), and polyisobutylene (PIB). Of course, melt yarns can also be composed of lesser-known polyolefins with desired properties. Polyolefins also include copolymers, such as ethylene-vinyl acetate (EVA) or copolymers of ethylene and acrylates.

[0036] In one embodiment, the polymer melt yarn is composed entirely of (100%) polyester. Polyester is used in approximately half of all textile products. By using polyester filaments as the raw material for the polymer melt yarn, approximately half of the disassembled textile products will not be contaminated with polyester components. As mentioned above, this is a crucial property for maintaining the quality of polyester textiles after disassembly. Furthermore, the inventors of this invention have discovered that this polymer is highly suitable as a yarn due to its high tensile strength, moderate elongation, and high flexibility. Moreover, polyester polymer filaments with the desired properties can be produced, making this polymer ideally suited for use as melt yarn in the production of textile products that can be disassembled automatically or semi-automatically.

[0037] According to embodiments of this invention, the polymer is composed of one or more polymers. Preferably, the molten yarn is composed of one type of polymer, and more preferably, if possible, the polymer molten yarn is composed of the same type of polymer as the textile it is sewn into. This has the advantage that any remaining fragments of molten yarn that may remain on the textile when it is disassembled will not cause contamination because they are made of the same material. Therefore, the purity of the disassembled textile is not affected, thus ensuring the quality of the material by avoiding yarn contamination.

[0038] This invention relates to a textile article that can be disassembled automatically or semi-automatically. Specifically, the textile article will consist of individual workpieces, wherein at least some workpieces are joined together by a connecting device, and for the connecting device, at least one polymer melt yarn is used, as described above. The melt yarn will transform from a solid phase to a liquid or semi-liquid phase at a temperature equal to or higher than the melting temperature of the yarn. The textile article is preferably configured to decompose into the first and second parts by heating the textile article and / or the connecting device to a temperature at least 5°C higher than the melting temperature of the polymer melt yarn.

[0039] In one embodiment, the molten yarn is heated directly or indirectly. Direct heating can be achieved, for example, using a hot air gun or by immersing the textile in warm water. Indirect heating may involve placing the textile in an oven, in a chamber through which hot air flows, or in a chamber that emits infrared radiation. Other techniques known in the art may also be used.

[0040] In one embodiment, the connecting device includes a polymer melt yarn and a standard yarn, or a polymer melt yarn and a second polymer melt yarn, each comprising a different polymer material.

[0041] In one embodiment, the polymer melt yarn further comprises one or more thermally conductive reinforcing materials selected from the group consisting of metals, ceramic materials, graphite, or combinations thereof. To prevent thermal degradation of the textile material during the disassembly phase, the duration of the textile product's exposure to a heat source must be minimized. Therefore, it is desirable to increase and accelerate the thermal conductivity of the melt yarn without altering its melting temperature.

[0042] Metals such as aluminum possess high intrinsic thermal conductivity. Their high density and electrical conductivity represent cost-effective opportunities and further innovation in wearable technology applications in textiles. Metals can be introduced into sewing yarns in various ways. On one hand, metals can be added as powder during melt spinning, or introduced as short fibers during mechanical spinning and twisting processes. Finally, they can be added as a coating during the finishing process of the sewing thread (after twisting).

[0043] In another or further embodiment, ceramic materials are added to the molten yarn. These ceramic materials can be incorporated into the yarn as fillers or powders during the melt spinning process. Examples of available ceramic materials include oxides, such as alumina or magnesium oxide. Calcium carbonate Magnetite (MagniF), aluminosilicate Boron nitride Dry grinding of mica In another or further embodiment, graphite is added to the molten yarn.

[0044] Sewing or processing textiles using needles and thread can be accomplished with various types of stitches. An added advantage of the current method is that it can be performed using sewing machines currently available in the textile industry without modification or replacement. This means that implementing this invention does not require a large investment from the company. In the textile industry, different sewing machines are used to form various types of stitches, which typically fall into one of the categories of chain stitch, lockstitch, overlock stitch, or cover stitch.

[0045] In one embodiment, the textile article is a jacket, wherein the material is selected from the group consisting of cotton, polycotton, polyethylene terephthalate (PET), polyamide, or combinations thereof, and wherein the textile recycling interference is selected from the group consisting of zippers, buttons, elastic bands, fastening bands, or combinations thereof.

[0046] In another embodiment, the textile product is trousers, wherein the material is selected from the group consisting of cotton, cotton blends, polyethylene terephthalate (PET), or combinations thereof, and wherein the textile recycling interference is selected from the group consisting of zippers, buttons, blended fabrics, or combinations thereof.

[0047] In another embodiment, the textile article is sportswear, wherein the material is selected from the group consisting of polyamide, polyethylene terephthalate (PET), or combinations thereof, and wherein the textile recycling interference is selected from the group consisting of zippers, elastic bands, fastening bands, or combinations thereof.

[0048] In another embodiment, the textile article is workwear, wherein the material is selected from the group consisting of cotton, cotton blends, polyethylene terephthalate (PET), polyamide, or combinations thereof, and wherein the textile recycling interference is selected from the group consisting of zippers, buttons, reflective tapes, logos, fastening straps, or combinations thereof.

[0049] In another embodiment, the textile article is a mattress or mattress cover, wherein the material is selected from the group consisting of polyethylene terephthalate (PET), cellulose materials, or combinations thereof, and wherein the textile recycling interference includes one or more non-recyclable mixtures selected from the group consisting of polyolefins, viscose fibers, acrylic resins, wool, lyocell, or combinations thereof and / or textile recycling interference selected from the group consisting of zippers, RFID tags, or combinations thereof.

[0050] The present invention is further described by way of the following non-limiting examples, which further illustrate the present invention and are not intended to, nor should be construed as, limiting the scope of the present invention.

[0051] Description of examples and / or figures

[0052] The present invention will now be further illustrated with reference to the following examples. The present invention is by no means limited to the embodiments presented in the given examples or drawings.

[0053] Example 1

[0054] Figure 1A front view of an embodiment of the present invention is shown. In this embodiment, the textile 1 is a jacket made of cotton, with a zipper 2 attached along the front. These zippers function to adjust the fit and provide ventilation, making the garment suitable for various weather conditions. However, the presence of these zippers introduces a significant challenge during the recycling process. This recycling obstacle can be overcome by incorporating the connecting device described above. Furthermore, the jacket includes disruptors 3 on the underside of the body and on the sleeves, in which elastic fabric is added for proper fit. The jacket includes a hood 4, which includes a disruptor in the form of a drawstring 5, adapted to tighten the hood.

[0055] Example 2

[0056] Figure 2 A front view of an embodiment of the present invention is shown. In this embodiment, the textile 1 is a pair of trousers made of a blend of cotton, polyester, and cotton, with metal buttons 6 designed at the waist and pockets. These buttons provide durability and strength to the garment, especially in frequently used areas. In addition to the metal buttons 6, the trousers also include a metal zipper 7 for adjusting the fit of the garment.

[0057] Example 3

[0058] Figure 3 A front view of an embodiment of the present invention is shown. In this embodiment, the textile 1 is workwear typically subjected to harsh environments. The cotton work shirt is characterized by a logo 8, reflective tape 9, and buttons 6 to enhance its durability and functionality. While these components are necessary for the strength and usability of the garment, they complicate the end-of-life handling of the attachments. The non-recyclable nature of these buttons means they must be removed before the cotton can be processed, thus increasing recycling labor and costs. By incorporating the fastening device described above, the obstructions can be easily removed from the work shirt.

[0059] Example 4

[0060] Mattresses are constructed using a combination of PET and / or cellulose fibers. The mattresses include polyolefin blends that provide additional structural support and flexibility, zippers, buttons, and labels. While these polyolefins are essential for the mattress's functionality, they introduce significant challenges in recycling. Polyolefins do not blend seamlessly with PET or cellulose fibers during recycling, necessitating their separation to allow for the reuse of other components, ultimately complicating the product's sustainability. When structural support elements are sewn into the mattress using polymer melt yarn, they can be easily separated by heating the mattress or its components to at least the melting temperature of the melt yarn used.
