Description

Technical Field

[0001] This invention relates to a recycled material, and more particularly to a recycled material made from recycled fibers. Background Technology

[0002] Industrialization and fast fashion have led to a large and diverse range of ready-made garments and other textiles. However, due to the increased emphasis on environmental protection and resource sustainability over the past decade or so, there has been development of ways to reuse out-of-season or obsolete textiles. Reuse methods include, for example, shredding fabrics to make yarn for sound insulation panels and carpets, or blending them with other fibers to create non-woven products and cleaning fabrics. Additionally, these fabrics can be mixed and granulated with resin materials to reduce reliance on petrochemical raw materials; however, current mixing technology limits the amount of fiber that can be added and also restricts production capacity. Summary of the Invention

[0003] This invention provides a method for manufacturing regenerated fiber granules, which reduces the time required to produce the granules, thus increasing the yield per unit time. It also allows for an increase in the amount of regenerated fiber added.

[0004] The present invention also provides a method for manufacturing recycled fiber pellets, which helps to increase the output per unit time and improve the stability of the finished product, avoiding the batch variation problem existing in the current process.

[0005] To achieve one or more of the above-mentioned objectives or other objectives, an embodiment of the present invention provides a method for manufacturing recycled fiber pellets, comprising the steps of: providing a fiber material, wherein the fiber material comprises a plurality of fiber blocks and the fiber blocks have a specific size; providing an interface compatibilizer, mixing the interface compatibilizer and the fiber material to form a mixture; kneading the mixture; providing a solid resin, adding the solid resin during the kneading of the mixture to continue kneading and forming a mixture agglomerate, wherein the kneading time is equal to or less than 5 minutes; and extruding and pelletizing the mixture agglomerate to form a plurality of recycled fiber pellets, wherein the fiber material accounts for 20-80% of the weight percentage of the mixture agglomerate.

[0006] In one embodiment of the invention, the step of kneading the mixture and forming a mixture agglomerate further includes kneading using a plurality of screws, and the kneading time is further equal to or less than 3 minutes. Kneading is also known as mixing.

[0007] An embodiment of the present invention also provides a method for manufacturing recycled fiber pellets, comprising the steps of: providing a first fiber material, wherein the first fiber material comprises a plurality of fiber blocks and the fiber blocks have a specific size; providing a first interface compatibilizer and a first solid resin, mixing the first interface compatibilizer, the first solid resin and the first fiber material to form a first mixture, wherein the first fiber material accounts for 20-80 wt% of the weight percentage of the first mixture; kneading the first mixture to form a first mixture agglomerate, wherein the kneading time is equal to or less than 5 minutes; providing a second fiber material, a second interface compatibilizer and a second solid resin, mixing the second fiber material, the second interface compatibilizer and the second solid resin to form a second mixture; extruding and pelletizing the first mixture agglomerate to form a plurality of first recycled fiber pellets; kneading the second mixture to form a second mixture agglomerate, wherein the kneading time is equal to or less than 5 minutes; and extruding and pelletizing the second mixture agglomerate to form a plurality of second recycled fiber pellets.

[0008] In one embodiment of the present invention, the above-mentioned method for manufacturing regenerated fiber particles further includes the steps of: providing a third fiber material, a third interface compatibilizer and a third solid resin; mixing the third fiber material, the third interface compatibilizer and the third solid resin to form a third mixture; kneading the third mixture to form a third mixture agglomerate, wherein the kneading time is equal to or less than 5 minutes; and extruding and pelletizing the third mixture agglomerate to form a plurality of third regenerated fiber particles.

[0009] Because the mixing time of this invention is equal to or less than 5 minutes, the time required to produce recycled fiber pellets is shorter, which helps to increase the output per unit time. Since the second fiber material, the second interface compatibilizer, and the second solid resin can be mixed simultaneously during the mixing of the first mixture, or the first mixture agglomerates can be extruded and pelletized while the second fiber material, the second interface compatibilizer, and the second solid resin are being mixed, or the second mixture can be mixed while the first mixture agglomerates are being extruded and pelletized, this allows for continuous production, which helps to increase the output per unit time, avoids the batch variation problems existing in current processes, and improves the stability of the finished product.

[0010] The above description is merely an overview of the technical solution of the present invention. In order to better understand the technical means of the present invention and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of the present invention more apparent and understandable, preferred embodiments are described below in detail with reference to the accompanying drawings.

[0016] This invention provides a method for manufacturing regenerated fiber granules, which requires less time to produce the granules and allows the steps to be performed continuously, thus increasing yield per unit time and improving the stability of the finished product, avoiding batch variation problems present in current batch manufacturing processes. Furthermore, the manufacturing method provided by this invention features optimized process conditions, which is beneficial for improving the performance and characteristics of the regenerated fiber granules.

[0017] Figure 1 This is a schematic flowchart of a manufacturing method according to an embodiment of the present invention. Figure 1 As shown, the process includes steps S110-S150. Step S110: Providing a fibrous material, wherein the fibrous material comprises multiple fiber blocks, and the fiber blocks have a specific size. Step S120: Providing an interface compatibilizer, mixing the interface compatibilizer and the fibrous material to form a mixture. Step S130: Performing kneading of the mixture. Step S140: Providing a solid resin, adding the solid resin during the kneading of the mixture to continue kneading and form a mixture agglomerate, wherein the kneading time is equal to or less than 5 minutes. Step S150: Extruding and pelletizing the mixture agglomerate to form multiple recycled fiber pellets, wherein the fibrous material accounts for 20-80% of the weight percentage of the mixture agglomerate. Further explanation follows.

[0018] Step S110: The fiber material in step S110 can be a natural or man-made fiber material. Natural fiber materials can be derived from plants, animals, and fabrics made from natural fibers. Natural fibers include, but are not limited to, cotton, linen, silk, wool, or combinations thereof. Man-made fiber materials can be derived from fabrics made from man-made fibers, including, but not limited to, polyester fibers, nylon fibers, acrylic fibers, acetate fibers, or combinations thereof. In a preferred embodiment of the invention, the fiber material is preferably derived from recycled fabrics, such as clothing, curtains, bedding, towels, covers, and carpets made from natural fibers, man-made fibers, or combinations thereof.

[0019] In several embodiments of the present invention, step S110 may further include recycling the fabric and crushing the fabric to obtain fiber blocks. Fiber blocks can also be obtained from the recycling of various wastes, such as agricultural waste, household waste, and food industry waste. The fabric can come from recycling centers, material suppliers, or sales channels such as clothing, curtains, bedding, towels, covers, and carpets. Additionally, sources of fiber materials include bamboo fiber and waste straw from agricultural or household waste, and pineapple fiber and coffee grounds from food industry waste. Methods for crushing the fabric can be based on known techniques and will not be described here. The fiber blocks obtained from recycling and crushing may have an average diameter of, for example, less than or equal to 10 millimeters (mm), but are not limited thereto.

[0020] Step S120: The interfacial compatibilizer in step S120 can coat the fibrous material and form a mixture having a state suitable for compounding. The interfacial compatibilizer may include at least one liquid resin. In several embodiments of the invention, the liquid resin may include epoxy resin, maleic anhydride copolymer, silane compound, or a combination thereof. The liquid resin may be selected depending on the regenerated fiber particles to be formed. For example, if the regenerated fiber particles are to be epoxy resin fiber particles, the interfacial compatibilizer selected in step S120 may be epoxy resin, but is not limited thereto. Multiple liquid resins may be used in combination. In the formed mixture, the fibrous material is the main component. In a preferred embodiment of the invention, the fibrous material may account for, for example, 90-98 wt% of the mixture.

[0021] In several embodiments of the present invention, step S120 may further include providing an auxiliary agent, and further mixing the interface compatibilizer, fiber material, and auxiliary agent when mixing the interface compatibilizer and fiber material. The auxiliary agent may include various functional components, for example, antioxidants, flow promoters, flame retardants, ultraviolet (UV) absorbers, abrasion and scratch resistant agents, or combinations thereof, wherein the antioxidant includes hindered phenols, thioesters, phosphite antioxidants, or combinations thereof. The auxiliary agent may be used, for example, to adjust the texture of the mixture to facilitate mixing, protect the fiber material during mixing, and avoid adverse effects of high temperatures on the mixture, but is not limited thereto. Auxiliaries with different functions may be used in combination. In embodiments of the present invention, the total amount of the auxiliary agent preferably accounts for 0.2-3.0 wt% of the mixture, for example, 0.2, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0 wt%. After deducting the weight percentage of fiber material (e.g., 90-98 wt%) and auxiliaries (0.2-3.0 wt%), the remainder is approximately the weight percentage of the interface compatibilizer. In embodiments of the present invention, the interface compatibilizer preferably accounts for 2-5% of the mixture, for example, 2, 2.5, 3, 3.5, 4, 4.5, or 5 wt%.

[0022] In several embodiments of the present invention, step S120 may also include providing a resin material. The resin material may include a solid resin such as plastic granules, and may further include a liquid resin as an interface compatibilizer. The resin material is mixed with a fiber material, and the mixture contains both the resin material and the fiber material. At this point, due to the addition of the solid resin, the weight percentage of the fiber material in the mixture becomes 20-80 wt%.

[0023] Step S120 can be performed, for example, in a mixer and / or a mixing tank. The mixer and / or mixing tank can be used for stirring at a specific speed. In a preferred embodiment of the invention, the mixer and / or mixing tank can be set to stir the fiber material, interface compatibilizer, and additives at a speed of 400-800 rpm, for example, 400, 500, 600, 700, or 800 rpm, or stir the fiber material, interface compatibilizer, solid resin, and additives, to obtain a homogeneous mixture. The stirring time can be, for example, 3-5 minutes.

[0024] Step S130: Step S130 uses high temperature to bring the mixture to a molten state and make it suitable for kneading. In this document, kneading is also synonymous with "kneading". In embodiments of the invention, it is preferred to use a plurality of screws for kneading, with a minimum of three, such as 3, 4, 5, 6, 7, or 8 screws. The screw temperature can be 120-250 degrees Celsius (°C), and preferably, for example, 120-140°C, such as 120, 140, or 160°C, and kneading is performed at a specific rotational speed. The kneading time can be less than 5 minutes, for example, 1, 2, 3, 4, or 5 minutes, and preferably less than or equal to 3 minutes, for example, 0.5, 1, 1.5, 2, 2.5, or 3 minutes. Because the number of screws is at least three, the kneading efficiency is high, which helps to shorten the kneading time and allows kneading to be performed at a lower temperature. Due to the high kneading efficiency, the relative amount of fiber material can be increased; and because the kneading time is shortened and the temperature is lower, the amount of additives can be further reduced. During mixing, the screw extrudes, kneads, and conveys the mixture. In several embodiments of the invention, the mixture can be mixed at speeds of, for example, 10-100 rpm (e.g., 10, 20, 30, 40, 50, 60, 70, 80, 90, 100 rpm) for 1-3 minutes to obtain a mixture agglomerate. The resulting mixture agglomerate preferably has good fiber dispersion uniformity.

[0025] In this embodiment of the invention, the solid resin provided in step S140 may be in the form of plastic granules. The material of the plastic granules may be a thermoplastic plastic such as polyethylene (PE), polypropylene (PP), polycarbonate (PC), or polyethylene terephthalate (PET), but is not limited thereto. The solid resin may also be the solid form of the aforementioned liquid resin. This invention does not limit the amount of solid resin used; however, in a preferred embodiment, the weight percentage of the fiber material in the blend aggregate is 20-80 wt%, and the weight percentage of the solid resin may be 30-50%. The weight percentage of the fiber material may further be 50-80 wt%. A higher amount of fiber material indicates a higher utilization rate of recycled materials and further reduces dependence on petrochemical raw materials. An appropriate weight ratio between the fiber material and the solid resin ensures that the resulting recycled fiber granules have sufficient fiber content and visual appeal, while also providing appropriate performance characteristics.

[0026] In addition to being added during mixing, as mentioned above, the solid resin can also be added first, that is, mixed with the mixture from step S120 before mixing begins. The mixing of the solid resin and the mixture from step S120 can be carried out in the mixer described above, but is not limited thereto. Alternatively, a portion of the solid resin can be mixed with the mixture first, and the remaining portion added during mixing.

[0027] Steps S130-140 can be performed, for example, in an extruder. The extruder has a plurality of screws as described above, capable of heating, extruding, kneading, conveying, mixing, or combinations thereof. In embodiments of the invention, the plurality of screws further includes at least one main screw 410 and a plurality of auxiliary screws 420. For example, there is one main screw 410 and seven auxiliary screws 420. Figure 2 As shown, the auxiliary screw 420 can be arranged in a planetary configuration around the main screw 410. During mixing, the main screw 410 can rotate at speeds of, for example, 10-100 rpm (e.g., 10, 20, 30, 40, 50, 60, 70, 80, 90, 100 rpm), while the auxiliary screw 420 can rotate and revolve relative to the main screw 410, thus achieving better mixing efficiency. The rotational and revolving speeds of the auxiliary screw 420 are variable and can be changed according to actual conditions during mixing.

[0028] In several embodiments of the present invention, steps S130-140 may be performed in a pelletizer. Hereinafter, a pelletizer is a machine capable of producing plastic pellets, such as recycled fiber pellets. The pelletizer may have an extrusion die having a plurality of screws as described above, and steps S130-140 may be performed in the extrusion die. The pelletizer may also have a feeding unit, such as a feeder, for adding the mixture, solid resin, or combination thereof from step S120 into the pelletizer. Furthermore, in several embodiments of the present invention, the pelletizer may further have a mixing module having, for example, a mixing tank, and may be used to perform step S120. The pelletizer may have a conveying unit, such as a conveyor belt, for conveying the mixture from step S120 to the extrusion die for steps S130-140.

[0029] Step S150: The agglomerate formed in step S140 preferably has a suitable hardness and can be extruded and passed through a die to produce agglomerates of a specific shape. The agglomerates of a specific shape are suitable for cutting into granules of a specific size. The die used in this embodiment of the invention is, for example, a die head with a specific aperture. The agglomerate extruded from the die head preferably has an elongated shape. The elongated agglomerate can be cut into multiple granules. Cutting can be performed at the die head outlet. The resulting granules can be recycled fiber masterbatch.

[0030] In several embodiments of the present invention, such as Figure 3 As shown, the method for manufacturing regenerated fiber particles may further include step S160: drying the regenerated fiber particles. The drying conditions may be at a temperature above room temperature, such as, but not limited to, 80°C, and the time may be, for example, 3-6 hours, but not limited to, this.

[0031] The present invention also provides a recycled fiber granule, manufactured by the aforementioned method. In several embodiments of the present invention, the recycled fiber granule comprises: fiber material, solid resin, interface compatibilizer, and additives. The fiber material accounts for 20-80 wt% of the recycled fiber granule by weight, the interface compatibilizer accounts for 2-5%, the additives account for 0.2-3.0 wt%, and the remainder is solid resin. The total weight percentage of the fiber material, solid resin, interface compatibilizer, and additives may be 100 wt%. More preferably, the weight percentage of the fiber material is 50-80 wt%.

[0032] The method for manufacturing recycled fiber granules of the present invention is preferably carried out in a continuous manner. That is, materials such as fiber materials, interfacial compatibilizers, mixtures, solid resins, or combinations thereof can be continuously fed in, and recycled fiber granules can be continuously discharged. Therefore, steps S110-S150 or S110-S160 are carried out continuously without interruption. Furthermore, because the feeding is continuous, steps at different stages can be carried out simultaneously. For example, if the current feeding has reached step S150, the subsequent feeding can reach the stage of steps S110, S120, S130, or S140. Also, if the current feeding has formed recycled fiber granules and discharged, the subsequent feeding will also form recycled fiber granules.

[0033] Figure 4 This is a schematic flowchart of a manufacturing method according to another embodiment of the present invention. Figure 4 As shown, the process includes steps S210-S270. Step S210: Provide a first fiber material, wherein the first fiber material comprises multiple fiber blocks, and the fiber blocks have a specific size. Step S220: Provide a first interface compatibilizer and a first solid resin, mix the first interface compatibilizer, the first solid resin, and the first fiber material to form a first mixture, wherein the first fiber material accounts for 20-80 wt% of the weight percentage of the first mixture. Step S230: Knead the first mixture to form a first mixture agglomerate, wherein the kneading time is equal to or less than 5 minutes. Step S240: Provide a second fiber material, a second interface compatibilizer, and a second solid resin, mix the second fiber material, the second interface compatibilizer, and the second solid resin to form a second mixture. Step S250: Extrude and pelletize the first mixture agglomerate to form multiple first recycled fiber pellets. Step S260: Knead the second mixture to form a second mixture agglomerate, wherein the kneading time is equal to or less than 5 minutes. Step S270: The second mixture agglomerates are extruded and pelletized to form a plurality of second regenerated fiber pellets. Further explanation is provided below.

[0035] Steps S230 and S240 can be performed simultaneously or substantially simultaneously, or steps S240 and S250 can be performed simultaneously or substantially simultaneously, or steps S250 and S260 can be performed simultaneously or substantially simultaneously. Furthermore, during steps S260 or S270, the third fiber material, the third interface compatibilizer, and the third solid resin can be further mixed, compounded, and pelletized.

[0036] Figure 4-5The illustrated embodiment may further include steps S310-S330. Step S310: Provide a third fiber material, a third interface compatibilizer, and a third solid resin; mix the third fiber material, the third interface compatibilizer, and the third solid resin to form a third mixture. Step S320: Perform kneading of the third mixture to form a third mixture agglomerate, wherein the kneading time is equal to or less than 5 minutes. Step S330: Extrude and pelletize the third mixture agglomerate to form a plurality of third recycled fiber pellets. Furthermore, steps S310 and S260 may be performed simultaneously or substantially simultaneously, or steps S310 and S270 may be performed simultaneously or substantially simultaneously, or steps S320 and S270 may be performed simultaneously or substantially simultaneously. Subsequent fiber materials, such as the fourth, fifth...Nth fiber materials, and interface compatibilizers, such as the fourth, fifth...Nth interface compatibilizer, are also processed in the same manner, and this cycle continues continuously.

[0037] In embodiments of the present invention, the fiber materials, such as the first, second, and third fibers, may be the same or different between different feeds, and the first, second, and third interfacial compatibilizers may also be the same or different. The conditions used for mixing, compounding, and pelletizing steps may also be the same or different. However, in a preferred embodiment of the present invention, the first mixture, the second mixture, and the third mixture are all compounded and subsequently extruded and pelletized using the same plurality of screws. Furthermore, at least steps S230, S250-S270, and S320-S330 can be performed in the pelletizer described above. Steps S220, S240, and S310 can also be performed in the pelletizer described above.

[0038] The components and process conditions of several embodiments of the present invention are further illustrated in Tables 1-2 below: Table 1

[0039] Table 2

[0040] Based on Tables 1 and 2, the main differences between the embodiments of the present invention and the comparative examples include: the embodiments are continuous processes, while the comparative examples are batch kneading processes. The embodiments also shorten the mixing time. Further differences between the embodiments of the present invention and the comparative examples include: 1) In the embodiments of the present invention, a plurality of screws as described above are used for mixing, and the temperature of the screws is 120-250°C.

[0041] 2) Following 1), the present invention embodiment ensures that the mixing time does not exceed 5 minutes.

[0042] 3) The embodiments of the present invention further increase the content of regenerated fibers. For example, in Examples 4 and 5, the content of regenerated fibers reaches 70%.

[0043] 4) The regenerated fiber particles obtained in the embodiments of the present invention generally have higher tensile strength, and as in Examples 6, 8-11, are significantly increased to greater than 60 kg / cm². 2 The increase in tensile strength reflects an improvement in the thermal aging of the components. Furthermore, in this embodiment, the shortened mixing time also reduces the heating time of the material, thus improving or preventing material aging and resulting in increased tensile strength of the recycled fiber particles.

[0044] 5) The recycled fiber granules obtained in the embodiments of the present invention have a melt index in an appropriate range, for example, 0.2-5.0 g / 10 min, and therefore have appropriate fluidity in the molten state, making them suitable for processing into downstream products.

[0045] In summary, the embodiments of the manufacturing method for recycled fiber pellets of the present invention require less time, especially shorter mixing time, thus helping to shorten the process. Furthermore, mixing and pelletizing steps can be performed continuously, thereby increasing output per unit time and avoiding batch variation problems present in current batch processes, thus improving the stability of the finished product. The embodiments of the present invention also employ optimized process conditions, including using multiple screws for mixing, lower temperatures, and shorter times, which are beneficial for improving the performance and characteristics of the recycled fiber pellets. For example, it helps to maintain fiber color and fiber pellet properties. Therefore, it can further provide better performance for downstream products using recycled fiber pellets as materials.
