Abstract
Description
Technical Field
[0001] The scope of this invention is primarily limited to recycling machines and methods for recovering textile waste, and secondarily to spinning machines and methods for reusing recovered textile fiber materials during the spinning process. This invention broadly encompasses integrated recycling and spinning devices and methods based on waste textile materials. More specifically, this invention relates to an integrated recycling and spinning machine that provides an integrated process for obtaining and spinning recovered textile fiber materials. Background Technology
[0002] EP3845323 A1, published on July 7, 2021, under the name of Kayren Joy Nunn, discloses an apparatus for deconstructing textile waste. In conventional recycling equipment, textile waste fabrics are shredded by a large-diameter tearing drum that operates at high speed and typically without temperature control, resulting in low-quality fibers containing short, dusty fibers. As an improvement, chemical or enzymatic treatment can be applied to the textile material through nozzles and passed through the material by vacuum suction. Textile treatment can involve vapor, solution, dispersion, or spray. Textile deconstruction involves rotating drums with cutting needles to achieve the desired level of deconstruction. Each rotating drum can be equipped with an internal temperature control device to prevent temperature-induced fiber degradation. Figures 4 to 5 As shown, a conveyor belt is used to transport textile materials between the processing station and the decomposition station. A redeposition unit with a suction device can be used to separate and output lightweight textile materials and further recycle heavy textile materials. Downstream products can be transferred to an output storage tank and, depending on the processing, can be used for healthcare, personal care, baby products, or undergo subsequent fiber refining.
[0003] On July 12, 2019, under the name of Jiangnan University, CN110004539 A disclosed an environmentally friendly pure yarn production method, which includes the following steps: the suction cotton and residual roving ends collected in viscose fiber spinning are opened and combed into single fiber state by a mixing opener and a carding opener; the single fibers and Lenzing viscose fibers that have been opened and sorted are fed together and evenly; the fibers are shaped into viscose rolls; the viscose rolls are sequentially carded, drawn twice, roved and spun to prepare environmentally friendly pure yarn.
[0004] CN110067057 A, published on July 30, 2019, under the name of Jiangnan University, discloses a method for producing environmentally friendly blended yarn. The method includes the following steps: cleaning and carding recycled polyester fibers processed from waste polyester materials, and pre-drawing to prepare a recycled polyester sliver; cleaning and carding cotton fibers to form a cotton sliver; performing three draws and blending processes on the recycled polyester sliver and cotton sliver to form a blended sliver; and roving and spinning the blended sliver to prepare the final desired environmentally friendly blended yarn. The draw process involves specific steps that improve the blending effect of the recycled polyester fibers and cotton fibers during the draw process.
[0005] WO2020 / 152717, published on July 30, 2020, in the name of Sharadha Terry Products Ltd., discloses a system and method for manufacturing textile products from roving waste. The method is used to manufacture 100% recycled ring-spun yarn from waste generated during spinning, and additionally for manufacturing recycled ring-spun yarn from cotton waste, combed cotton waste, and carding waste, producing 100% cotton ring-spun yarn.
[0006] EP1234900 A1, published on August 28, 2002, under the name of Maschinenfabrik Rieter AG, discloses a cleaning method and apparatus for removing particulate impurities such as plastic particles or other particles from raw cotton fiber materials.
[0007] US3308944A, published on March 14, 1967, under the name of Reclamation Trades Res Organis, discloses a method for separating mixtures of textile fibers by electrostatic means. This separation process involves dispersing the fibers in an airflow and electrostatically charging them. Wool fibers in the dispersion acquire a positive charge, and polyester fibers acquire a negative charge, both with sufficient magnitude for separation purposes. The different decay rates of the same charge on different fibers in the airflow can also be used to separate the fibers.
[0008] Therefore, currently known textile recycling production lines produce recycled textile fiber materials for direct use, for example, in napping materials, or alternatively for packaging and later use in a subsequent separate spinning process. The subsequent separate spinning process can combine yarn recovered from textile waste, roving waste, etc., with virgin yarn to produce recycled yarn with improved quality. The spinning process can involve rotor spinning or ring spinning. Summary of the Invention
[0009] The object of this invention is to provide an apparatus and method for simplified yarn manufacturing using fiber waste. This object is achieved by the subject matter set forth in the independent claims. Some embodiments are given in the dependent claims and combinations thereof, and further improvements are provided.
[0010] This invention relates to an integrated recycling and spinning machine for manufacturing yarn from textile waste, and more particularly to an integrated recycling and spinning machine for implementing a method disclosed herein for the integrated recycling and spinning of textile waste into yarn, the machine comprising: a. A recycling unit, configured to recover textile waste into recycled fiber materials. It integrates with the following: b. Drawing and spinning units, which are configured to produce yarns containing recycled fiber materials.
[0011] The input product for an integrated recycling and spinning machine can be textile waste, such as garment and / or yarn waste, which is typically provided in bales. The output product of an integrated recycling and spinning machine is yarn, which is typically wound onto bobbins or cones for subsequent use in weaving, knitting, or other fabric manufacturing machines. In this context, "integrated" means that the recycling unit, drawing unit, and spinning unit are combined in the same location into a single machine or machine assembly, particularly in a manner that allows for immediate handover of intermediate fiber recycled products between manufacturing stages or steps. Intermediate fiber recycled products are not in bales.
[0012] Therefore, integrated recycling and spinning machines provide an integrated workflow from recycling textile waste to ready-to-use yarn products. This can offer significant advantages in terms of logistics, production efficiency, and production costs. In particular, this is advantageous for small-batch textile waste recycling and yarn spinning. The invention can also relate to the coordinated operation of recycling units, drawing units, and spinning units.
[0013] Textile waste can include natural fibers (such as cotton) and synthetic fibers (such as elastic fibers), which can be extracted in the recycling unit. Virgin natural fiber materials can also be incorporated into the drafting and spinning units to improve yarn quality.
[0014] More specifically, the present invention includes an integrated recycling and rotor spinning production line that avoids at least one of the following: using a separate recycling machine to obtain recycled textile fiber material; a baler associated with the recycling machine for compressing the recycled textile fiber material into bales; a bale transport device for transporting the bales of recycled textile fiber material to a separate location, particularly to a spinning mill; a bale opener for re-opening the recycled textile fiber material; and a separate spinning machine for spinning the recycled or blended virgin and recycled textile fibers into yarn.
[0015] In an embodiment, the recycling unit may include a cutter for cutting textile waste into fragments, a fiber opening machine production line for pre-opening the textile fibers contained in the fragments, and at least one fine opening machine production line for finely opening the pre-opened textile fibers, all together to obtain recycled fiber material. The fine opening production line or stage allows a soft opening process to obtain fibers that can retain longer fiber lengths. This also has the advantage that garment waste and other waste such as yarn waste can be used as input materials in integrated recycling, drawing, and spinning processes.
[0016] In embodiments of integrated recycling and spinning machines, the recycling unit may include several parallel fine opening machine production lines, some or all of which are configured to feed recycled fiber material in the form of fiber slivers or fiber bundles into the spinning unit's spinning machine. Feeding the recycled fiber sliver directly into the spinning machine (with or without intermediate drawing processes) provides a very simplified workflow because procedures previously necessary are no longer required and can be eliminated, including preparation steps for packing, the packing itself, pack transportation, and subsequent unpacking and carding at the spinning mill.
[0017] In embodiments, the drawing unit may include at least one of the following: a card dover module for concentrating or bundling recycled fiber streams, fibers, or fiber pads into recycled fiber slivers or bundles; a drawing station, particularly an integrated automatic leveling drawing system, for drawing and / or leveling the recycled fiber slivers or bundles; and a sliver can filling station, particularly an automatic sliver can winder, for loading the drawn recycled fiber slivers or bundles into cans, which may be referred to as the final sliver. In this document, sliver production (i.e., fiber bundling and fiber bundle drawing) provides an intermediate product, typically the final sliver, suitable for immediate feeding into subsequent stages or steps of integrated recycling, drawing, and spinning machines and methods; however, it is less suitable or at least less advantageous for transport compared to conventionally packaged recycled fiber material. This contrasts with conventional recycling machines, which output recycled fiber material in bales to allow for transport to various locations, typically to spinning mills.
[0018] In embodiments, the spinning unit may include at least one of the following: a spinning machine, particularly a rotor spinning machine, for spinning the free end of a sliver into yarn; a spinning machine, particularly a compact ring spinning machine with an integrated roving frame, for drafting (e.g., packaged) recycled fiber slivers or fiber bundles into roving and for spinning the roving into yarn; a sliver mixing frame for mixing recycled fiber slivers or fiber bundles with each other to improve fiber uniformity; and a sliver mixing frame for mixing recycled fiber slivers or fiber bundles with virgin fiber material to improve fiber quality. While spinning itself is well known, the combination of recycling and drawing processes with spinning processes (especially when roving drafting is included) offers significant technical improvements, logistical simplifications, and economic savings compared to conventionally known individual operating processes.
[0019] In one embodiment, at least one or each fine opening machine production line may have a designated drawing station, particularly an automatic leveling drawing system (IGS), integrated downstream of it for drawing and / or leveling and recycling fiber slivers. In another embodiment, at least one or each drawing station includes a designated sliver filling station, particularly an automatic sliver winder.
[0020] In an embodiment, each carding doffer module may be equipped with an integrated automatic leveling and drawing system (IGS) to feed clean, carded fiber slivers into an attached automatic sliver filling station or sliver winder.
[0021] In other embodiments, at least one or each sliver filling station (particularly an automatic sliver winder) may be connected to a designated or shared sliver exchange and / or transfer station and / or to a sliver mixing and drawing frame for at least one of the following: providing a first (typically larger) sliver and / or a second (typically smaller) sliver for filling or refilling them; providing virgin fiber material to the sliver for mixing it with recycled fiber material, particularly with recycled fiber sliver; transferring the first and / or second sliver to the spinning machine. Refilling may, in particular, involve refilling the sliver after use (i.e., after evacuation); or filling the smaller sliver for the spinning machine with recycled fiber sliver from the larger sliver filling station of the drawing unit.
[0022] In an embodiment, the first or larger sliver can have a diameter, for example, in the range of 120 cm to 150 cm, as used in, for example, a conventional carding machine, while the second or smaller sliver can have a diameter, for example, in the range of 50 cm to 60 cm, suitable for spinning machines such as free-end rotor spinning machines or ring spinning machines, which are equipped, for example, with a roving draw frame and a compact spinning system (referred to as a compact ring spinning machine).
[0023] In an embodiment, the sliver exchange and / or transfer station may include a sliver conveyor system for: (i) delivering filled sliver cans from at least one or each sliver filling station to a spinning machine and / or a sliver mixing and drawing frame; and / or (ii) re-delivering empty sliver cans from the spinning machine and / or the sliver mixing and drawing frame to at least one or each sliver filling station; and / or (iii) circulating blended fiber sliver cans from the sliver mixing and drawing frame to the spinning machine, and circulating empty sliver cans from the spinning machine to the sliver mixing and drawing frame.
[0024] If several fine opening machine production lines exist, they are preferably arranged in parallel. In this document, "specified" means that the specified devices are provided in a one-to-one correspondence with each other. Thus, each fine opening machine production line can be equipped with its own drawing station, its own can filling station, and / or its own can exchange and / or transfer station. This has the advantage that the fine opening machine production lines can operate independently of each other, and multiple fine opening machine production lines can operate in parallel, so that their combined production capacity for intermediate products (such as recycled fiber slivers for canned drawing) can be matched with the spinning capacity of the spinning machine, especially when considering the blending of recycled natural fiber material with an additional amount of virgin natural fiber material.
[0025] In an embodiment, the recycling unit includes a fiber opening machine production line equipped with a buffer container for producing and collecting, in particular, storing pre-opened textile fiber material. The buffer container is connected in parallel to one or more (e.g., three) fine opening machine production lines via feed pipes. Each fine opening machine production line is connected downstream to a designated carding doffer module, a designated drawing frame station (in particular an integrated automatic leveling drawing frame system), and a designated sliver filling station (in particular an automatic sliver winder) for delivering the drawn recycled fiber slivers or fiber bundles to a spinning unit with or without a sliver mixing drawing frame, in particular a free-end rotor spinning machine or a ring spinning machine with an integrated roving drawing frame.
[0026] In this embodiment, even without a buffer container, exactly one fine opening machine production line can be directly connected to the previous fiber opening machine production line.
[0027] In the embodiments, the production capacities of the recycling unit, the drawing unit, and the spinning unit, particularly the yarn spinning capacity of free-end rotor spinning machines or ring spinning machines equipped with roving drawing frames, can be adapted to each other.
[0028] In the embodiments, the production capacity of the fiber opening machine production line and / or the storage capacity of the buffer container, the number and production capacity of one or more parallel fine opening machine production lines, and the production capacity of the drawing unit (especially multiple carding doffer modules, multiple drawing stations or multiple integrated automatic leveling drawing systems and multiple sliver filling stations or multiple automatic sliver winders) can be matched with the production capacity of the spinning unit (especially free-end rotor spinning machines or ring spinning machines with integrated roving drawing frames) with or without sliver mixing drawing frames.
[0029] In an embodiment, the sliver mixing and drawing frame may include: a sliver feeding system for feeding recycled fiber slivers from a first supply sliver can and optionally natural fiber slivers from a second supply sliver can; a sliver drawing and mixing system for homogenizing and / or mixing the slivers; and a canning system for filling the homogenized and / or mixed slivers into the second sliver can for delivery to a spinning machine.
[0030] In one embodiment, the sliver mixing and drawing frame may include a sliver can conveyor system for transporting a second sliver can filled with mixed sliver to the spinning machine and for transporting an empty second sliver can from the spinning machine back to the sliver mixing and drawing frame.
[0031] In embodiments, the recycling unit may include at least one of the following: an integrated carding station; and an integrated extraction module, particularly an electrostatic and / or mechanical extraction module, for extracting synthetic fiber materials from mixed textile waste fiber materials containing both synthetic and natural fiber materials. Preferably, each fine opening machine production line includes at least one such integrated extraction module, particularly an electrostatic and / or mechanical extraction module, for extracting synthetic fiber materials from mixed textile waste fiber materials containing both synthetic and natural fiber materials. Such refinement stages or steps may be present in any suitable part of the integrated recycling, drawing, and spinning machines and methods.
[0032] In an embodiment, the recycling unit does not include at least one of the following: a fiber air extraction system for transporting fibers to a baler; a baler agglomerator; a baler container; a baler for compressing the recycled textile fiber material; and a chemical fiber processing unit.
[0033] In an embodiment, the integrated drawing and spinning unit does not include at least one of the following: a bale opener for opening bales of recycled textile fiber material; and a carding machine for carding the opened recycled textile fiber material.
[0034] In some embodiments, textile waste may include natural fiber materials comprising at least one of the following: cotton fiber, hemp fiber, flax fiber, ramie fiber, sisal fiber, bamboo fiber, silk fiber, and mixtures thereof. In other embodiments, textile waste may include synthetic fiber materials comprising at least one of the following: polyester fiber, polyurethane fiber, elastic fiber, polyamide fiber, viscose or rayon fiber, acrylic fiber, nylon fiber, and mixtures thereof.
[0035] In another aspect, the present invention relates to a method for the integrated recycling and spinning of textile waste into yarn, particularly using an integrated recycling and spinning machine as disclosed herein, the method comprising the following steps: a. In the recycling unit, textile waste is recycled into recycled fiber materials. b. The recycled fiber material, in the form of a fiber stream, fiber floss, or fiber mat, is fed into the drawing unit, and the recycled fiber material is drawn into slivers, particularly into fiber slivers. c. Manufacturing yarn containing recycled fiber materials in a spinning unit.
[0036] An integrated approach to recycling textile waste and manufacturing yarns containing recycled textile waste fiber materials offers advantages as outlined above, particularly in terms of technological improvements, logistical simplification, and economic savings compared to conventional recycling lines and conventional spinning mills located in different locations and operating in a separate and uncoordinated manner.
[0037] In an embodiment, step a may include at least one of the following: cutting textile waste in a cutter; pre-opening the fiber waste in a fiber opening machine production line to obtain pre-opened fiber material; fine opening the pre-opened fiber material in a fine opening machine production line to obtain recycled fiber material; and extracting synthetic fiber material from mixed textile waste fiber material containing synthetic fiber material and natural fiber material in an integrated extraction module (particularly an electrostatic and / or mechanical extraction module).
[0038] In an embodiment, step b may include at least one of the following: receiving a fiber stream or fiber velvet or fiber mat from the fine opening machine production line of the recycling unit; concentrating or bundling the recycled fiber stream or fiber velvet or fiber mat into recycled fiber slivers or fiber bundles in the carding doffer module of the drawing unit; drawing the recycled fiber slivers or fiber bundles in the drawing station of the drawing unit, particularly in an integrated automatic leveling drawing system; and loading the drawn recycled fiber bundles into cans in the can filling station of the drawing unit, particularly in an automatic can winder.
[0039] In an embodiment, step 1 may include at least one of the following: mixing the recycled fiber sliver of the drawing with the virgin fiber material in a sliver mixing frame; spinning the sliver into yarn in a rotor spinning machine; drafting the recycled fiber sliver of the drawing into roving; and spinning the roving into yarn in a ring spinning machine.
[0040] In the embodiments, the operation and production capacity of the recycling unit, particularly the operation and production capacity of the parallel fine opening machine production line, and the operation and production capacity of the drawing unit and the spinning unit are matched with each other.
[0041] In an embodiment, the method does not include at least one of the following steps: suctioning the recovered textile fiber material toward a packer in a fiber air suction system; agglomerating the recovered textile fiber material in a packer agglomerator; collecting the recovered textile fiber material in a packer container; compressing the recovered textile fiber material into bales in the packer; transporting the bales containing the recovered textile fibers to another location, particularly to a spinning mill; and carding the bales of textile fiber material in a carding machine.
[0042] In an embodiment, the method does not include at least one of the following steps: opening a package containing recycled textile fiber material in a package opener; and combing the opened recycled textile fiber material in a carding machine.
[0043] It will be understood that the foregoing general description and the following detailed description present embodiments with optional features and are intended to provide an overview or framework for understanding the nature and features of this disclosure. The accompanying drawings are included to provide further understanding and are incorporated into and form a part of this specification.

Figure 9 The strips are mixed and strung together. Detailed Implementation
[0045] Reference will now be made in detail to certain embodiments, examples of which are illustrated in the accompanying drawings, which show some, but not all, features. The embodiments disclosed herein may be embodied in many different forms and may include variations in one or more features or aspects, and are generally combinable with each other. The embodiments should not be construed as limiting; rather, these embodiments are provided to ensure that this disclosure will meet applicable legal requirements. Generally, the same reference numerals should refer to the same or similar parts or portions.
[0046] Figures 1 and 2 show schematic perspective and top views of a prior art textile recycling machine 100. Textile waste, such as garment waste or yarn waste, is transported on conveyor belt 2a to cutter 2. The cut textile waste is transported on another conveyor belt 3a to a first buffer container 3 for intermediate storage of textile chips or fragments or yarn waste. The first buffer container 3 can also be fed with residues, such as unopened or insufficiently opened textile fiber material, which is collected from fine opening stages 10, 11, and 12 via air duct 4 and guided back to the first coagulant 5. The first buffer container 3 feeds its contents, for example, via another conveyor belt to a first fiber opening machine production line 6, which pre-opens the fibers contained in the cut textile waste to obtain single, not yet fully parallel fibers. The pre-opened fiber material is collected via feed pipe 7 and transported to a second buffer container 8 for intermediate storage. The second container 8 feeds its contents via feed pipe 9 to three fine opening machine production lines 10, 11, and 12. Feed duct 9 is typically implemented as a fiber air suction feed system. In fine opening machine production lines 10, 11, and 12, textile fiber material is finely opened to obtain recycled textile fiber material with sufficient quality (typically canned quality). The first fiber opening machine production line 6 and subsequent fine opening machine production lines 10, 11, and 12 are typically equipped with suction or vacuum-driven filtered air ducts 13 connected to filter 130 for collecting and filtering fiber waste originating from the fiber opening process, such as very short fiber fragments or dust. The recycled textile fiber material is then collected via air duct 15, condensed in a second condenser 16, stored in container 17, and then compressed into bales in a baler 18. The second condenser 16 acts like a sieve to separate fibers from the airflow, allowing the fibers to fall into container 17. Typically, approximately 200 kg to 300 kg of recycled textile fiber material is compressed into a bale. Therefore, the conventional recycling machine 100 and recycling method start with packages of clothing waste and / or yarn waste and produce packages of recycled textile fiber materials for subsequent transportation for further processing.
[0047] Figure 3 shows a schematic perspective view of a conventional carding machine 19, a sliver filling station 20, and a rotor spinning machine 21, located in a separate location, such as a spinning mill, to which bales of recycled textile fiber material must be transported. The bales must be opened in an opener (not shown), and the recycled fiber material must then be carded in a separate carding machine 19 to re-straighten and clean the recycled textile fiber material after it has been coagulated in a second coagulant 16 and compressed together in a baler 18, and to restore or improve the quality of the recycled textile fiber material. Therefore, the separate carding stage 19 largely compensates for the adverse effects of baling on the fiber quality of the recycled textile fiber material.
[0048] The carding machine 19 typically includes a drawing frame 190 for producing recycled fiber slivers, which are fed via a can filling pipe 20a to a can filling station 20 for filling into a first larger can 20b. The canned sliver can be mixed with virgin fiber material and then filled into a second smaller can 21b. The second can 21b supplies slivers to the rotor spinning machine 21.
[0049] Figure 4 and Figure 5 An embodiment of the integrated recycling and spinning machine 300 of the present invention is shown, which specifically includes a recycling unit 301, a drawing unit 302 and a spinning unit 303.
[0050] The recycling unit 301 differs in various respects from the prior art recycling machine 100 described above. Textile waste, such as clothing waste, industrial textile waste, or yarn waste, can be transported on conveyor belt 32a to cutter 32, which may include rotary rollers, a cutting machine, or other cutting devices. The cut textile waste can be transported on a separate conveyor belt 33a to a first buffer container 33 for intermediate storage of textile chips or fragments or yarn waste. The first buffer container 33 can also be fed with residues such as unopened or insufficiently opened textile fiber materials, which are collected again from the fine opening stages 40, 41, 42 via air ducts 34 and guided back to the coagulant 35. The coagulant 35 acts like a sieve to separate fibers from the airflow so that the fibers can fall into the first buffer container 33. The first buffer container 33 feeds its contents (such as garment slivers or industrial textile scraps or yarn waste) via, for example, another conveyor belt, to a first fiber opener production line 36, which pre-opens the fibers contained in the chopped textile waste to obtain single fibers. These single fibers are typically not yet perfectly parallel and are still unevenly distributed. The pre-opened fiber material can be collected via feed pipe 37 and transported to a second buffer container 38 for intermediate storage. The second buffer container 38 can feed its contents via feed pipe 39 to, for example, three fine opener production lines 40, 41, and 42. Feed pipe 39 can typically be implemented in the form of a fiber air suction feed system. In the fine opener production lines 40, 41, and 42, the textile fiber material can be finely opened to obtain recycled textile fiber material with sufficient quality (typically canned quality). The first opening machine production line 36 and subsequent fine opening machine production lines 40, 41, and 42 may preferably be equipped with suction or vacuum-driven filter air ducts 43 connected to filter 430 for collecting and filtering fiber waste, such as very short fiber fragments or dust, originating from the fiber opening process.
[0051] According to the present invention, the integrated recycling and spinning machine 300 further includes a drawing unit 302 for producing slivers, particularly recycled fiber slivers. Embodiments of the invention are described below. Figure 4 and Figure 5 The above is illustrated schematically and discussed below.
[0052] The drawing unit 302 may include a carding doffer module 44 and / or a drawing station, particularly an automatic leveling drawing system 45, 451, 452, 453, preferably for each fine opening machine production line 40, 41, 42, which are arranged in parallel with each other and sequentially with the aforementioned pre-opening machine fiber production line 36. Each carding doffer module 44 receives an annular fiber stream, fiber pile, or fiber pad extending in two planar dimensions (i.e., length and width dimensions) delivered from its designated fine opening machine stage 40, 41, 42, and concentrates it into a relatively circular recycled fiber bundle or recycled fiber sliver suitable for canning. As a numerical example, the fiber stream or pile or pad may have a typical width of about 1 m to 1.5 m and a typical height of about 5 mm to 50 mm, and is concentrated or bundled into a relatively circular recycled fiber sliver with a diameter of about 30 mm. This recycled fiber sliver can be made to have canning quality. In terms of fiber quality (particularly including fiber length and fiber orientation), the recycled fiber sliver can correspond to a conventionally carded sliver, which is routinely obtained from the recycled textile fiber material after being opened in a bale opener and carded in a carding machine 19, as explained in the context of Figures 1 to 3. However, in this disclosure, the fiber air extraction system 15, the bale collector 16, the bale container 17, the bale 18, the bale transport device (not shown), the bale opener (not shown), and the separate carding machine 19 for re-stratifying the opened recycled textile fiber material are not required.
[0053] Drawing stations (particularly integrated automatic drawing systems 451, 452, 453) are used for drawing and / or leveling recycled fiber slivers, thereby producing recycled fiber slivers with improved fiber uniformity. One, several, or each drawing station 451, 452, 453 may include, for example, a breaker drawframe for producing the first recycled fiber sliver and / or a finisher drawframe for producing the last recycled fiber sliver. This improves sliver quality and uniformity, making the recycled fiber sliver usable in subsequent yarn spinning processes, and optionally in roving drafting and yarn spinning processes.
[0054] The drawing unit 302 may also include a sliver filling station 46, such as an automatic sliver winder 46, preferably sliver filling stations 461, 462, and 463 for each fine opening machine production line 40, 41, and 42. Sliver filling stations 461, 462, and 463 are used to load the recycled fiber slivers from the drawing into sliver cans, particularly the first sliver can or the large sliver can 46b.
[0055] like Figures 4 to 8 As shown, the sliver filling stations (e.g., automatic sliver winders 46, 461, 462, 463) can also be individually or jointly connected to the sliver exchange and / or transfer space 48, and optionally to the sliver mixing and sliver rack 49, for operator-handled semi-automatic or fully automatic actions including at least one of the following: exchanging a first (typically larger) sliver can 46b and / or a second (typically smaller) sliver can 47b for filling or refilling them or for refilling from the first sliver can 46b into the second sliver can 47b; supplying virgin fiber material or virgin fiber sliver to an additional supply sliver can 490d for mixing with recycled fiber material, particularly recycled fiber sliver, in the mixing station 49; and transferring the smaller sliver can 47b to the spinning machine 47. In particular, the second smaller sliver can 47b is sized to supply recycled and optionally mixed fiber sliver to each spinning station of the spinning machine 47. For example, the first large strip 46b has a diameter in the range of 120 cm to 150 cm. For example, the second small strip 47b has a diameter in the range of 50 cm to 60 cm.
[0056] Figure 6 and Figure 7 Showing more details Figure 4 and Figure 5 The integrated recycling and spinning machine 300 is further equipped with an automated can exchange and / or transfer station 48 or can transport system 48. The can exchange and / or transfer station 48 may include: a can conveyor system 480, such as a forward conveyor belt 481, for delivering filled cans 480b from at least one or each can filling station 461, 462, 463 to the can delivery space 482 of the spinning machine 47; and a can conveyor system 480, such as a backward conveyor belt 484, for re-delivering empty cans 480a from the can removal space 483 of the spinning machine 47 to at least one or each can filling station 461, 462, 463.
[0057] Alternatively or additionally, the refilling and / or mixing of recycled fiber slivers with virgin fiber material and / or the movement of sliver cans 47b between the drawing unit 302 (particularly the sliver can filling station 46) and the spinning machine 47 may be performed by personnel or may involve manual procedural steps performed by personnel.
[0058] Figure 8Showing more details Figure 6 and Figure 7 The integrated recycling and spinning machine 300 is further equipped with a sliver mixing frame 49 for mixing fiber materials of different qualities (particularly virgin or natural fiber materials and recycled fiber materials (fiber blending frame)) or for homogenizing or further homogenizing the recycled fiber materials themselves. Herein, the sliver exchange and / or transfer station 48 may include: a sliver conveyor system 480, such as a forward conveyor belt 481, for delivering filled sliver cans 480b from at least one or each sliver filling station 461, 462, 463 to the sliver delivery space 482 of the sliver mixing frame 49; and a sliver conveyor system 480, such as a backward conveyor belt 484, for re-delivering empty sliver cans 480a from the sliver removal space 483 of the fiber mixing station 49 to at least one or each sliver filling station 461, 462, 463.
[0059] Use according to technical standards ( Figures 8 to 10 ) or avoid using ( Figures 6 to 7 The sliver mixing and drawing frame 49 is specifically based on: (i) the quality of the obtained recycled fiber sliver, (ii) the production of a quality-improved recycled fiber sliver by optionally incorporating virgin fiber sliver, (iii) the quality of the yarn produced therefrom, and (iv) the requirements of the selected drawing and spinning units 302, 303 or drawing and spinning method steps on sliver cohesion or stability.
[0060] For example, recycled fiber slivers may include relatively short fibers that, when excessively drawn or parallelized in the drawing frame 49, may result in low cohesion or even breakage of the fiber sliver, and / or may become more cohesive or stable by incorporating relatively long virgin fibers. Another criterion for using or not using the drawing frame 49 may be that, compared to ring spinning with integrated roving drawing frames and roving compaction or cohesion that requires fiber slivers with greater cohesion or stability, free-end rotor spinning can be operated with fiber slivers with less cohesion or stability.
[0061] Figure 9 and Figure 10A sliver blending and drawing frame 49 is shown in more detail. It may include sliver blending and drawing frames 491, 492, 493, and 494, comprising: a sliver feeding system 491 for feeding recycled fiber slivers from a first supply can 490c and optionally virgin or natural fiber slivers from a second supply can 490d; a sliver drawing and blending system 492 for homogenizing and / or blending the slivers; and a can-loading system 493 for filling the homogenized and / or blended slivers into second cans 490b, 47b for delivery to the spinning machine 47. The first supply can 490c may be filled with recycled fiber slivers from filled cans 480b of sliver can filling stations 46, 461, 462, and 463; or it may be a filled can 480b itself. The second supply can 490d may be delivered from an external source.
[0062] In addition, the sliver mixing and drawing frame 49 may include a sliver can conveyor system 494 for transporting a second sliver can 490b filled with mixed sliver to the spinning machine 47 and for transporting an empty second sliver can 490a from the spinning machine 47 back to the sliver mixing and drawing frame 49.
[0063] Spinning unit 303 includes at least one spinning machine 47, which can produce yarn directly from or including recycled fiber slivers in a package (i.e., recycled fiber slivers with package quality).
[0064] Throughout this application, spinning machine 47 may include or may be a rotor spinning machine 47 for spinning the free end of a sliver into yarn. Furthermore, spinning machine 47 may include or may be a ring spinning machine 47 having an integrated roving frame for drafting the fiber sliver into roving and for spinning the roving into yarn; in particular, spinning machine 47 may include or may be a ring spinning machine equipped with a roving frame and optionally a compact spinning system (hereinafter referred to as a compact ring spinning machine). Such compact ring spinning machines are disclosed, for example, in unpublished international patent application PCT / EP2022 / 067075 entitled “Ring spinning machine for spinning yarn,” the contents of which (including the drawings) are incorporated herein by reference in their entirety.
[0065] Furthermore, as mentioned above, the spinning machine 47 may include a sliver mixing frame 49 for mixing recycled fiber slivers with each other to improve fiber uniformity, and / or may include a sliver mixing frame 49 for mixing recycled fiber slivers with natural or virgin fiber materials to improve fiber quality. For example, in the case of cotton materials, the recycled textile fiber material may be mixed with virgin fiber material in a selectable proportion.
[0066] As an alternative or supplement to the (multiple) mixing stations 49, one, several, or each fine opening machine production line 40, 41, 42 may also include multiple cascaded fine opening stages for refining the recycled textile fiber material to obtain recycled fiber slivers with package quality directly (i.e. without mixing with virgin fiber material), so that the spinning machine 47 (typically a rotor spinning machine 47) can produce yarn of sufficient quality for weaving, knitting, etc., from 100% recycled textile fiber slivers.
[0067] In another aspect, the present invention also relates to a method for the integrated recycling and spinning of textile waste into yarn, the method comprising the following steps: a. In recycling unit 301, textile waste is recycled into recycled fiber materials. b.

Further embodiments of the extraction method involve the use of an integrated extraction module 50 as disclosed in International Patent Application PCT / EP2023 / 061681, as described herein or cited.
[0080] Throughout this application, natural fiber materials are or comprise cellulose fiber materials, such as, for example, cotton fiber, hemp fiber, flax fiber, ramie fiber, sisal fiber, bamboo fiber, or mixtures thereof. Cellulose fibers have important advantages such as low density, low cost, recyclability, and biodegradability. Natural fiber materials may also be or comprise silk fibers.
[0081] As discussed, textile waste may contain a mixture of natural and synthetic fibers, which may require integrated extraction module 50 or extraction method steps.
