Description

Spinning system and spinning method Technical Field

[0001] The present disclosure relates to the field of textile technology, and in particular to a spinning method and a spinning system for sheet materials. Background Art

[0002] China is a major producer of clothing and industrial textiles and the world's largest supplier and exporter of clothing. The global textile and apparel industry consumes 98 million tons of non-renewable resources annually, and this demand is growing rapidly annually. Driven by "fast fashion," mass production has become the norm in apparel production to meet mass consumer demand. Fiber parameters such as length, fineness, strength, uniformity, and maturity directly impact the quality and price of yarn and fabric. Fiber length is a key factor influencing each spinning step and the final yarn properties. A high short fiber content can lead to spinning difficulties or increased yarn breakage rates. Furthermore, the inherent properties and defects of some functional fibers limit their potential for yarn formation. Additional mechanical modifications increase overall production costs. Overproduction of textile materials also leads to significant waste. Statistics show that China's cumulative textile waste output reaches 140 million tons. Only a small fraction of these textiles can be recycled, while the majority take hundreds of years to decompose.

[0003] On the other hand, the recycling and sales of textile waste in China are relatively low, and most (87%) used textiles (including clothing) are incinerated or sent to landfills, which also causes a large amount of textile waste and pollutes the environment.

[0004] Therefore, how to improve the utilization rate of short fiber raw materials and waste textiles, promote resource recycling, and reduce waste generation is an urgent problem to be solved.

[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute prior art known to ordinary technicians in the field.

[0081] Textile recycling refers to scraps, samples, and used textile clothing generated during the textile and clothing production process. The raw materials can be, but are not limited to, natural or synthetic fiber materials such as cotton, linen, polyester, and nylon.

[0082] Ultra-short fibers are fibers less than 20mm in length that are directly or indirectly obtained from nature or chemically synthesized. These fibers are also known as non-woven fibers because they cannot be directly used for normal spinning. Under certain conditions, it is possible to extend the length of ultra-short fibers to 20-35mm.

[0083] In the industry, fibers with a length of 35 to 150 mm are generally referred to as short fibers. The technical solution disclosed in the present invention is mainly used for ultra-short fibers.

[0084] Figure 1A is a schematic diagram of a spinning system according to one embodiment of the present disclosure. As shown in Figure 1A , the spinning system includes: a strip forming device 12, comprising a cutter that moves in a set direction to cut a sheet of material into strips; or a fixed cutter that rotates the sheet in a specific direction to cut the sheet into strips of a set length and width; a pre-finishing device 14 for mechanically or chemically treating the strips to make them suitable for spinning; and a yarn forming device 13 for twisting at least one of the strips into textile yarn.

[0085] In one embodiment, the strip-forming device includes a cutter or a one-time forming cutting device, which moves along a set direction to cut the sheet material to obtain a strip material; or the cutter is fixed in a horizontal position and rotated in a specific direction to cut the sheet material into strip materials of set length and width and perform processing optimization according to use requirements; the yarn-forming device includes a twisting device, a winder, a twisting shaft, a pre-treatment and post-treatment device, which is used to twist at least one strip material into textile yarn and perform processing optimization according to use requirements.

[0086] In one embodiment, the strip forming device 12 uses sheet materials as raw materials. The sheet materials are not limited to substrates and woven products. The sheet materials can be woven, knitted, non-woven, film or composite materials obtained through conventional or unconventional mechanical or chemical textile processing, and are not limited to the above-mentioned sheet materials.

[0087] In one embodiment, the sheet material further includes any sheet currently sold in the market; or any sheet after specific optimization.

[0088] In one embodiment, the sheet material, the raw material includes various conventional and unconventional fibers in a fiber ratio according to certain gram weight parameters.

[0089] In one embodiment, the conventional or unconventional fiber material is a fiber raw material from a single component source or a fiber raw material from a mixed component source.

[0090] In one embodiment, the raw materials include various conventional and unconventional fibers, conventional fibers include natural and artificial fibers; unconventional fibers include textile recycled materials, spun combed fibers, low-strength fibers, various elastic materials, and one or more non-textile fibers, such as metal, plastic, and non-textile recycled materials, and are not limited to the above.

[0091] In one embodiment, the sheet material is subjected to conventional or chemical textile processing to obtain a woven material, a knitted material, a non-woven mesh, a film material or a composite material, and is not limited to the above.

[0092] In one embodiment, the woven material is characterized in that the structure is not limited to parallel, twill, satin, loop, lehenge, or jacquard. In one embodiment, the knitted material is characterized in that the structure is not limited to single-sided, double-sided, jacquard, terry, or fleece, and is not limited to the above.

[0093] In one embodiment, the non-woven mesh is characterized in that: the structure is not limited to single point spacing distance or line-surface distance such as spunlace, heat sealing, pulp airflow, wet method, spunbond, meltblown, needle punching, weaving, film, coating, etc.

[0094] In one embodiment, the nonwoven mesh may have a specific traction multiple, and is not limited to the above. In one embodiment, the nonwoven mesh may include a specific embossed structure and a mesh structure or a three-dimensional structure, and is not limited to the above.

[0095] In one embodiment, the sheet material can be a single layer reprocessed or a multi-layer mesh combined process. In one embodiment, the sheet material can be a mixed sheet material method, such as a sheet material made by various combinations of hot air, hydroentanglement, bonding, etc.

[0096] In one embodiment, the sheet material may be subjected to various finishing processes, characterized by including single point spacing distance or line surface distance such as spunlace, heat sealing, pulp airflow, wet method, spunbond, meltblown, needle punching, weaving, film, spraying, dyeing, etc., but not limited to the above.

[0097] In the above embodiment, the advantages of sheet materials are utilized: 1) a relatively short industrial chain; 2) low cost; 3) low fiber requirements; 4) a wide variety of web-forming processes. After industrial chain integration, the traditional non-woven fabric chain and the spinning chain are combined to effectively reduce the weaving cost of non-high yarn count yarns, improve productivity, and can be used for secondary yarn utilization of coarse, short, and hard fibers in textile waste; in addition, the parameter requirements of the raw material fibers required for traditional spinning can be greatly reduced, which is conducive to the application of new natural material yarns. The fibers after web formation can form the required mechanical tensile requirements, which greatly expands the range of raw materials for spinning.

[0098] Figure 1B shows a schematic diagram of a spinning system according to an embodiment of the present disclosure. As shown in Figure 1B , the spinning system for ultrashort fibers includes: a web-forming device 11 for forming ultrashort fiber material fed into the web-forming device into a sheet-like material; a strip-forming device 12, including a cutter or a one-step cutting device that moves along a set direction and cuts the sheet-like material to obtain a strip-like material; and a yarn-forming device 13 for twisting at least one strip-like material into a textile yarn. For example, the yarn-forming device may include a twisting shaft that rotates and twists at least one strip-like material into a textile yarn.

[0099] In the above embodiment, the ultra-short fiber material is formed into a sheet material and then cut into strip material, which effectively solves the problem that the raw material fiber cannot be directly formed into textile yarn due to insufficient length. After the strip material is twisted, a yarn with tensile properties that meets the requirements and can be used for textile is formed, which greatly broadens the range of raw materials for spinning; when various raw materials including waste materials can be utilized in large quantities, the cost of textile yarn is reduced.

[0100] In one embodiment, the web-forming device includes a mesh frame for evenly distributing the ultrashort fiber material on the mesh frame to form a mesh. The mesh frame can have different physical forms, such as fixed, movable, rigid, or flexible. The fibers can be distributed on the mesh frame using wet or dry laying methods. The thickness of the fibers distributed on the mesh frame can be measured by the amount of fiber delivered to the mesh frame and the weight of the fibers distributed on the mesh frame. The sheet material output by the web-forming device can also have different structures, such as embossed, plain, and mesh.

[0101] In one embodiment, the web forming device may further include a drying device for drying the sheet material. In one embodiment, the web forming device may further include one or more of a spunlace device, a glue spraying device, a heat sealing device, and a needle device for curing the sheet material.

[0102] In one embodiment, the spinning system includes a fiber conveying device, which includes an air flow output device, the air flow outlet of the air flow output device is opposite to the mesh frame, and the air flow output device brings out the fiber raw materials contained therein through high-speed jet air flow. The fiber raw materials in the air flow are captured by the mesh frame and laid on the mesh frame.

[0103] In one embodiment, the raw materials are not limited to substrates and textile sheet materials. Sheet materials include ready-made or specially optimized woven materials, knitted materials, non-woven fabrics, films, and composite materials. In one embodiment, woven materials can be obtained by conventional weaving devices including shuttle and shuttleless devices through the interweaving of warp and weft yarns to obtain woven materials, and are not limited to various structures such as plain, twill, satin, and jacquard. In one embodiment, knitted materials are obtained by conventional knitting devices including flat machines, circular knitting machines, and jacquard knitting devices to obtain knitted sheet materials, and are not limited to single-sided, double-sided, and jacquard structures. In one embodiment, various non-woven fabric devices are used to obtain non-woven sheet materials, and the way of distributing fibers on the mesh can also include wet laying and dry laying, and the weight of the fibers distributed on the mesh is measured. The sheet materials output by the web-forming device can also include different structures such as embossing, plain weave, and mesh.

[0104] In one embodiment, the cutter cuts the edges of the cut sheet material at intervals on each side, so that the sheet material is cut into continuous strips.

[0105] Classification is based on the relative relationship between the direction of movement of the cutter and the sheet material. In one embodiment, the cutter is at least one horizontal cutter, and the strip forming device includes a guide. The horizontal cutter reciprocates in the horizontal direction along the guide to cut the sheet material into strips of a predetermined length and width. In another embodiment, the cutter is at least one vertical cutter, and the vertical cutter reciprocates in the vertical direction to cut the sheet material into strips of a predetermined length and width.

[0106] The cutter is categorized by its shape. In one embodiment, the cutter is a wheel-shaped cutter that reciprocates horizontally to cut sheet material into strips of a predetermined length and width. In another embodiment, the cutter is a V-shaped cutter that reciprocates horizontally to cut sheet material into strips of a predetermined length and width. In yet another embodiment, the V-shaped cutter can also be a U-shaped cutter. The cutter's movement and the method of securing the cutter to the guide can employ existing mechanical structures.

[0107] Figure 2 shows a schematic diagram of a strip-forming device according to an embodiment of the present disclosure. As shown in Figure 2, the strip-forming device 200 includes a cutter 202, which moves along a predetermined (set) direction to cut the sheet material 203 placed on the supporting platform 204 into strips. After the sheet material is cut, a continuous strip material is formed, and the width of the strip material is not less than 0.1 mm. The winder 301 then rotates at a set speed to spirally wind the strip material on the winder. The spiral winding can ensure consistent yarn tension. The winder is equipped with a tension spring to control the winding tightness, and the tension is adjusted according to the strength of the strip material itself. The winding speed depends on the fiber material and the yarn count, and can be adjusted accordingly. In addition, the winding speed of coarse yarn is faster than that of fine yarn, so as to avoid accumulating too much yarn in the same position, resulting in an excessively large bobbin volume. The winding action can be performed while the cutter 202 is cutting, or the strip material formed can be wound onto the winder after the cutter 202 has completed cutting a sheet of material, and the strip material is wound onto the winder in a spiral shape. In one embodiment, the mesh is cut into strips continuously, such as in a bow shape. In one embodiment, after the cutting begins and a small strip of material is formed, one end of the strip material is fixed to the winder for rotation.

[0108] In one embodiment, the cutter 202 moves on a horizontal plane along the carrying track 201 relative to the carrying platform 204 and the sheet material 203 disposed on the carrying platform 204 to switch the cutting position.

[0109] In one embodiment, the position of the cutter 202 relative to the carrier platform 204 remains unchanged, but the sheet material 203 on the carrier platform 204 moves horizontally relative to the carrier platform 204 and the cutter 202 to switch the cutting position. For example, a crawler-type moving structure may be provided between the sheet material 203 and the carrier platform 204; the carrier platform may be a vacuum suction platform that secures the sheet material by vacuum suction; or a weight may be used to secure the sheet material to the carrier platform 204. The feeding and receiving method may be a semi-automatic or fully automatic conveyor belt.

[0110] In one embodiment, as shown in FIG3 , the cutter is two cutters 202A and 202B arranged in parallel, and the two cutters are staggered a certain distance from each other so that the two cutters can form a bow character by completing one cut on the sheet material.

[0111] In one embodiment, the strip-forming device further includes a guide, and the cutter moves along the guide to cut the sheet material into strip materials of set length and width. The guide includes, for example, an X-direction, and / or a Y-direction and / or a Z-direction guide. For example, in one embodiment, the strip-forming device includes an X-direction guide and a Z-direction guide, and the cutter is fixed to the X-direction guide, so that the cutter can perform an X-direction linear cutting motion, and can also move along the Z-direction after one X-direction cutting is completed, thereby performing a Z-direction position switching motion.

[0123] In one embodiment, the pre-finishing device includes a soaking treatment device.

The soaking treatment device includes a conveying device 1001, a reeling device 1002 (also referred to as a soaking and reeling device), a soaking device 1003, a drying device 1004, and a reeling device 1005 (also referred to as a soaking and reeling device). The strip is fed from the reeling device 1002 into a soaking tank 1003 containing a prepared liquid at a specific speed. At the same time, the soaking tank 1003 maintains the activity of the liquid at a specific temperature so that the strip completely absorbs the liquid, and the soaked strip is sent to the drying device 1004 via the conveying device for drying, and finally wound to the reeling device 1005 for storage.

[0124] In one embodiment, the pre-finishing device includes a spray treatment device for spray pre-treatment of the strip material. The spray treatment includes an unwinding device, a conveying device, a coating device, a drying device, and a winding device.

The prepared liquid is sprayed from the nozzle onto the strip material. The spray-treated strip material is then conveyed to a drying device for drying and wound to a winding device for storage.

[0125] In one embodiment, the pre-finishing device is a part of the yarn-forming device, and the strip material fed into the pre-finishing device is stretched and then output to the yarn-forming device for twisting to form textile yarn.

[0126] 11 shows a flow chart of more than one pre-finishing device according to one embodiment of the present disclosure, the pre-finishing device including a stretching device 1101, a soaking device 1102, and a spraying device 1103. The pre-finishing devices can be arranged in an order according to the characteristics of the strip or the use requirements.

[0127] In one embodiment, the strip material yarn product can be subjected to single or multiple post-processing, and the post-processing device includes a covering device and a plying device. The post-processing device can be an integrated molding device or a diversion process.

[0128] FIG12 is a schematic diagram showing the post-processing of yarn according to an embodiment of the present disclosure; strip-shaped yarn can be coated with strip-shaped materials, conventional yarns, fancy yarns, thick strips, tubular materials, sheet materials, and filaments. The strip-shaped yarn product serves as the core, and the cotton yarn is used as the covering yarn for coating, or low-count or multi-strand cotton yarn serves as the core, and high-count strip-shaped yarn product serves as the covering yarn. The core count must be greater than the covering yarn count to ensure that the covering yarn completely covers the core. The coating device also includes a T-shaped hollow spindle 1203, which pre-wraps the covering yarn 1205 around a specific winding bobbin 1204 and fixes the hollow spindle 1203. The core 1201 is fed into the hollow spindle 1203 via a roller. The hollow spindle 1203 rotates in a specific direction to wrap the covering yarn 1205 around the core and obtain the coated yarn 1202.

[0129] In another embodiment, strip yarn can be plied with strip material, conventional yarn, fancy yarn, sliver, tubular material, sheet material, or filament. The strip yarn and one or more conventional yarns, fancy yarns, sliver, tubular material, sheet material, or filament are fed to a twisting reel via rollers. The rollers rotate at a specific speed to plied two or more strips, conventional yarns, fancy yarns, sliver, tubular material, sheet material, or filament to produce a plied yarn. This spinning process optimizes the properties or increases the strength of the yarn and can be applied to industrial or functional fabrics.

[0130] In one embodiment, the spinning system further includes a fiber processing device 80 connected to the web forming device 81 for fiberizing and combing the raw material into an ordered state before feeding it into the web forming device 81. For example, the fiber processing device 80 is connected to the web forming device 81, such that the outlet of the fiber processing device is located above or at one end of the web forming device, so that the fiber raw material output by the fiber processing device 80 can be fed into the web forming device 81. The raw material fed into the fiber processing device 80 can be, for example, one or more of recycled textile scraps, textile samples, and waste materials that cannot be used for normal spinning. In one embodiment, the raw material fed into the fiber processing device 80 is a single-component ultra-short fiber material, such as recycled cotton waste from a production line, with a fiber length of less than 8 mm; short fibers formed by fiberizing recycled textile waste, with a fiber length of less than 12 mm; and recycled fibers that cannot be used for normal spinning, with a fiber length of less than 20 mm. In one embodiment, the raw material fed into the fiber processing device 80 is ultra-short fiber material from a variety of sources, with a variety of fiber lengths. In one embodiment, the raw materials fed into the fiber processing device 80 include ultra-short cotton fibers, textile recycled materials, spinning combed fibers, and / or biofunctional fibers. Biofunctional fibers include plant fibers, shrimp shells, crab shells, dandelion fibers, chitosan fibers, alginate fibers, etc., wherein the plant fibers are herbal fibers, woody fibers, or a combination thereof. The technical solution disclosed in the present invention can be used to solve the utilization of ultra-short natural fibers, but does not rule out the practice of incorporating other fiber raw materials in production practice. The cotton fiber raw materials and other raw materials after single fiberization, or the mixture after mixing with other functional fiber materials, the raw materials used for single fiberization include but are not limited to recycled scraps, textile samples, waste materials, short fiber raw materials, herbal fibers, woody fibers, shrimp shells, crab shells, and dandelion fibers, which are the same or diverse. The type of material components and the uniformity of fiber length have different effects on the final tensile strength and wear resistance of the yarn.

[0131] In one embodiment, raw materials fed into a web-forming device, including but not limited to textile scraps, samples, recycled old clothes, and biofunctional fibers, are subjected to single fiberization. The process includes crushing, splitting, soaking, filtering, and other operations on these raw materials to form single fibers that can be fed into the web-forming device.

[0132] Because scraps, samples, recycled clothing, and short fibers that cannot be put into production during traditional textile production can all be used in the spinning process and apparatus of this invention to produce yarn suitable for textile industry use, the cost of textile yarn is significantly reduced. Research shows that the production cost per ton of yarn can be reduced from the traditional 17,000-20,000 yuan to 7,000-8,000 yuan. This is undoubtedly a revolutionary contribution to the textile industry.

[0133] In one embodiment, the web-forming device 81 and the strip-forming device 82 are connected via a crawler belt, so that the sheet material generated by the web-forming device 81 is automatically transferred to the strip-forming device 82 for cutting by the strip-forming device 82 .

[0134] In one embodiment, the strip-forming device is physically connected to the yarn-forming device, or is located in a relatively close position, so that the strip material cut and generated by the strip-forming device can be directly or indirectly transmitted to the yarn-forming device for twisting into yarn after being wound onto the winder.

[0135] In one embodiment, the sliver-forming device and the yarn-forming device are integrated into a spinning device.

[0136] FIG13 shows a flow chart of a spinning method according to an embodiment of the present disclosure. As shown in FIG13 , the method includes:

[0137] S1302, obtaining sheet material.

[0138] S1304, cutting the sheet material to obtain strip material.

[0139] S1306, pre-finishing the strip material to make it suitable for spinning, wherein the pre-finishing includes mechanical treatment and / or chemical treatment.

[0140] S1308, twisting at least one of the strip-shaped material or non-strip-shaped material into a textile yarn at a specific contact point.

[0141] Figure 14 shows a flow chart of a spinning method according to an embodiment of the present disclosure. The spinning system of the above embodiment implements the following process steps of the spinning method to obtain yarn made of ultra-short fibers as raw materials:

[0142] S1402: Form the ultrashort fibers into a sheet-like material, for example, by using a web-forming device.

[0143] S1404: Cut the sheet material to obtain strip material. For example, a cutter of a strip forming device moves along a set direction to cut the sheet material to obtain strip material.

[0144] S1406, twisting the at least one strip of material input into textile yarn. For example, the at least one strip of material input is twisted into textile yarn by rotating a twisting shaft of a yarn forming device.

[0145] Through the above spinning system and spinning process, ultra-short fibers can be formed into yarns that can be used in the textile industry.

[0146] In one embodiment, the above-mentioned step S1402 also includes: the step of single-fiberizing the raw materials and combing them into an ordered state to obtain ultra-short fibers, and then sending them into a web-forming device.

[0147] In one embodiment, the cutter includes multiple cutters, and the edges of each side of the sheet material cut by the cutter are cut at intervals, so that the sheet material is cut into continuous strip material. The strip material can be cut into any width directly from 0.1mm to 5cm as needed, such as 0.5cm, 1cm, 2cm, 3cm, and 4cm. The tensile strength of the yarn obtained by the above steps, i.e., the tension, is determined by the width of the strip material and the twist displacement between the strip material and the core. The width of the strip material is generally proportional to its tensile strength, i.e., the wider the width of the strip material, the better the tensile strength. When the width of the strip material is constant, the effect of the twist angle on the tensile strength can be shown in conjunction with Figure 15:

[0148] The relationship between the strip material displacement δl and the yarn displacement δh is:

[0149] δl=δh×cosθ (1)

[0150] The length of the strip is l = h / cosθ, θ is the angle between the strip of material with a radius of r and the core, and h is the length of one circle of the core. Therefore, the relationship between the strain of the strip and the core can be expressed as:

[0151] Where,

[0152] ε f and ε y =δh / h are the strain of the strip material and the strain of the core respectively, and h is the length of one circle of the core.

[0153] Stress σ of strip material f for:

[0154] σ f =E f ε f (3)

[0155] Among them, E f Represents the modulus of elasticity or Young's modulus.

[0156] The equivalent area perpendicular to the strip is:

[0157] S1=2πrd×cosθ (4)

[0158] The total yarn tension is:

[0159] P=∫0 R σ f S1×cosθ=πR 2 E f εy cos 2 β (5)

[0160] E y =E f cos 2 β (6)

[0161] Where R is the radius of the yarn and β is the twist angle.

[0162] This shows that in addition to the width of the strip material itself, the twist angle when the strip material is twisted with the core also has a significant impact on the tensile strength of the yarn.

[0163] Between S1404 and S1406, a step of stretching the strip material may also be included:

[0164] The strip material is stretched by a stretching device before being fed into the spinning device. The stretching device includes a first roller group and a second roller group. The rotation speed of the second roller group is greater than the rotation speed of the first roller group. The strip material is input from the first roller group and output from the second roller group. The first roller group and the second roller group transport the strip material to the spinning device through a linkage action and simultaneously achieve the stretching of the strip material.

[0165] In S1406, a strip of material may be twisted alone, two or more strips of material may be twisted together, or the strip of material may be twisted together with other cores. The fineness of the core is greater than one-quarter of the fineness of the covering yarn.

[0166] Few existing methods can fully utilize textile recycled materials, waste materials, short-fiber cotton, etc. With the current rapid growth in textile demand, a large amount of textile fiber raw materials and waste textiles are discarded, resulting in significant waste and high costs. The present disclosure creatively proposes a solution that can recycle these scraps generated during the textile process, short-fiber raw materials that fail quality inspection, and / or separated and recycled textile fibers into the spinning process, ultimately producing high-quality wearable or industrial yarn. This solution can effectively alleviate the textile industry's resource shortages, large amounts of waste, and potential environmental pollution.
