Description

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 clothing supplier and exporter. The global textile and clothing industry consumes 98 million tons of non-renewable resources every year, and this demand is growing rapidly year by year. Under the influence of "fast fashion", mass production has become a common way of clothing production to meet the needs of mass consumption. Parameters such as fiber length, fineness, strength, uniformity, and maturity directly affect the quality and price of yarn and cloth. Among them, fiber length is a key factor affecting each spinning link and the final yarn performance. High short fiber content may cause spinning difficulties or increase the yarn breakage rate; at the same time, some functional fibers also limit their possibility of yarn formation due to their inherent characteristics and defects. Additional mechanical transformation will increase the total cost of production. The overproduction of textile materials has also led to a large amount of waste. Statistics show that China's cumulative output of waste textiles has reached 140 million tons, only a few of which can be recycled, and most of the other textiles 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 the prior art known to ordinary technicians in the field.

[0085] In one embodiment, the strip forming device 12 uses sheet materials as raw materials, and 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 by conventional or unconventional mechanical or chemical textile processing, and are not limited to the above-mentioned sheet materials.

[0086] In one embodiment, the sheet material also includes any sheet currently sold in the market; or any sheet after specific optimization.

[0087] 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.

[0090] 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.

[0093] In one embodiment, the nonwoven mesh sheet may have a specific traction multiple, and is not limited to the above. In one embodiment, the nonwoven mesh sheet may include a specific embossed structure and a mesh structure or a three-dimensional structure, and is not limited to the above.

[0106] Figure 2 FIG. 2 shows a schematic diagram of a strip forming device according to an embodiment of the present disclosure. Figure 2As shown, 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 carrying 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. Then the winder 301 rotates at a set speed to spirally wind the strip material on the winder. The spiral winding can ensure the consistency of the 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 the coarse yarn is faster than that of the fine yarn, so as to avoid accumulating too much yarn in the same position, resulting in an excessive volume of the bobbin. The winding action can be performed simultaneously when the cutter 202 is cutting, or the formed strip material can be wound on the winder after the cutter 202 completes the cutting of a sheet material, and the strip material is spirally wound on the winder. In one embodiment, the mesh is cut into strips continuously, for example, in a bow shape. In one embodiment, after the cutting starts and a small strip of material is formed, an end of the strip of material is fixed to a winder for rotation.

[0107] 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.

[0108] 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 moving structure is provided between the sheet material 203 and the carrier platform 204; or the carrier platform is a vacuum adsorption platform, which fixes the sheet material by vacuum adsorption; or a heavy object is used to fix the sheet material on the carrier platform 204, and the feeding and receiving method can be a semi-automatic or fully automatic conveyor belt.

[0109] In one embodiment, Figure 3 As shown, the cutters are two cutters 202A and 202B arranged in parallel, and the two cutters are staggered a certain distance from each other on the left and right sides, so that the two cutters can form a bow character by completing one cutting on the sheet material.

[0110] 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.

[0124] 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.

[0125] Fig.11 The flowchart shows more than one pre-finishing device according to one embodiment of the present disclosure, the pre-finishing device includes a stretching device 1101, a soaking device 1102 and a spraying treatment device 1103. The pre-finishing devices can adjust the sequence according to the characteristics of the strip or the use requirements.

[0126] In one embodiment, the strip material yarn product can be subjected to single or multiple post-processing, and the post-finishing device includes a covering device and a plying device. The post-finishing device can be an integrated molding device or a diversion process.

[0127] Fig.12 A schematic diagram of post-finishing of yarn according to an embodiment of the present disclosure is shown; 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 is used as the core, and the cotton yarn is used as the covering yarn for coating, or low-count or multi-strand cotton yarn is used as the core, and high-count strip-shaped yarn product is used 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 through a roller, and the hollow spindle 1203 rotates in a specific direction to wrap the covering yarn 1205 around the core and obtain the coated yarn 1202.

[0128] In another embodiment, the strip yarn can be plied with strip materials, conventional yarns, fancy yarns, thick strips, tubular materials, sheet materials, and filaments, and the strip yarn and one or more conventional yarns, fancy yarns, thick strips, tubular materials, sheet materials, and filaments are fed into the twisting shaft through rollers, and the rollers rotate at a specific speed to plied two or more strip materials, conventional yarns, fancy yarns, thick strips, tubular materials, sheet materials, and filaments to obtain plied yarns. The above spinning process optimizes the characteristics or enhances the strength of the yarn products, and can be applied to industrial or functional fabrics.

[0129] In one embodiment, the spinning system further comprises a fiber processing device 80, which is connected to the web forming device 81, and is used to feed the raw material into the web forming device 81 after single fiberization and combing to form an ordered state. For example, the fiber processing device 80 is connected to the web forming device 81, and 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 is fed into the web forming device 81. The raw materials fed into the fiber processing device 80 are, for example, one or more of textile recycling 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 cotton wool recycled from a production line, and the fiber length can be shorter than 8 mm; short fibers formed by single fiberization of waste recycled textiles, the fiber length can be shorter than 12 mm; and the fiber length of fibers that cannot be used for normal spinning that are recycled can be shorter than 20 mm. In one embodiment, the raw material fed into the fiber processing device 80 is ultra-short fiber materials from multiple sources, and the fiber length can include multiple types. In one embodiment, the raw materials fed into the fiber processing device 80 include ultra-short cotton fibers, textile recycling 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 herbaceous 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 exclude the practice of incorporating other fiber raw materials in production practice. The cotton fiber raw material and other raw materials after single fiberization, or a 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, herbaceous 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.

[0130] 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 fiberized. 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.

[0131] Since scraps, samples, recycled old clothes, and short fiber raw materials that cannot be put into production in traditional textile production can be used in the spinning process and device of the present invention to produce yarns that meet the needs of the textile industry, the cost of textile yarns is greatly reduced. Studies have shown that the production cost of each ton of yarn can be reduced from the traditional 17,000-20,000 yuan to 7,000-8,000 yuan. Undoubtedly, this contribution to the textile industry is subversive.

[0132] In one embodiment, the web-forming device 81 is connected to the strip-forming device 82 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 .

[0133] 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 a winder.

[0134] In one embodiment, the sliver-forming device and the yarn-forming device are integrated into a spinning device.

[0135] Fig.13 A flow chart of a spinning method according to an embodiment of the present disclosure is shown. Fig.13 As shown, the method includes:

[0136] S1302, obtaining sheet material.

[0137] S1304, cutting the sheet material to obtain strip material.

[0138] S1306, pre-finishing the strip material to make it suitable for spinning, wherein the pre-finishing includes mechanical treatment and / or chemical treatment.

[0139] S1308, twisting at least one of the strip-shaped material or non-strip-shaped material into a textile yarn at a specific contact point.

[0140] Fig.14 A flowchart of a spinning method according to an embodiment of the present disclosure is shown. 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:

[0141] S1402, forming the ultrashort fibers into a sheet-like material, for example, by using a web-forming device to form the ultrashort fibers into a sheet-like material.

[0142] S1404, cutting the sheet material to obtain the strip material. For example, the sheet material is cut by a cutter of a strip forming device moving along a set direction to obtain the strip material.

[0143] S1406, twisting the at least one strip material input into a textile yarn. For example, the at least one strip material input is twisted into a textile yarn by rotating a twisting shaft of a yarn forming device.

[0144] Through the above spinning system and spinning process, ultra-short fibers can be formed into yarns that can be used in the textile industry.

[0145] In one embodiment, the above step S1402 also includes: the step of subjecting the raw materials to single fiber processing and combing them into an ordered state to obtain ultra-short fibers, and then sending them into a web-forming device.

[0146] In one embodiment, the cutter includes a plurality of 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 materials. The strip materials can be cut into any width of 0.1mm-5cm according to needs, such as 0.5cm, 1cm, 2cm, 3cm, 4cm. The tensile properties of the spinning obtained by the above steps, that is, the tension, are determined by the width of the strip material and the twisting displacement of the strip material and the core. The width of the strip material is usually proportional to its tensile resistance, that is, the wider the width of the strip material, the better the tensile resistance. When the width of the strip material is constant, the influence of the twisting angle on the tensile resistance can be combined with Fig.15 As shown:

[0147] The relationship between the strip material displacement δl and the yarn displacement δh is:

[0148] δl=δh×cosθ (1)

[0149] The length of the strip material is l = h / cosθ, θ is the angle between a single strip material with a radius of r and the core, and h is the length of a circle of the core. Therefore, the relationship between the strain of the strip material and the core can be expressed as:

[0150]

[0151] In the formula,

[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 σf S1×cosθ=πR 2 E f ε y 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] It can be seen 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 great influence 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] There are few methods in the prior art that can fully utilize textile recycled materials, waste materials, short-fiber cotton, etc. At present, the demand for textiles is growing rapidly, and a large amount of textile fiber raw materials and waste textiles are discarded, resulting in great waste and high costs. The present disclosure creatively proposes a solution, which can reuse the scraps generated in the textile process, short fiber raw materials that cannot pass quality inspection, and / or separated and recycled textile old clothing fibers into the spinning process, and finally form high-quality edible yarn or industrial yarn, which can effectively alleviate the shortage of resources in the textile industry, the waste of a large amount of waste materials and potential environmental pollution.

This application is intended to cover any variations, uses, or adaptations of the present disclosure that follow the general principles of the present disclosure and include common knowledge or customary techniques in the art that are not disclosed in the present disclosure.
