Description

Technical Field

[0001] The invention relates to the technical field of nonwoven fabrics, in particular to a method for preparing a nonwoven fabric sheet by utilizing recycled ready-made clothes and a closed mixing and pulling device using the same. Background Art

[0002] As we all know, the process of recycling garments into non-woven fabrics usually includes crushing, drawing, cotton thinning, cotton finishing and needle punching, and finally non-woven fabrics are made. This process can transform discarded garments into other usable items, reflecting the concept of environmental protection.

[0003] However, the existing process causes significant environmental pollution, including the generation of large amounts of lint and dust, as well as industrial safety and health management issues. In addition, the process itself is complex and inefficient. Although recycling garments for reuse is environmentally friendly, the environmental impact and efficiency issues in the actual production process indicate that existing technologies are in urgent need of improvement. In the context of the current society's increasing concern about carbon emissions and sustainable development, it is particularly important to develop a more environmentally friendly and efficient garment recycling technology. Summary of the invention

[0004] The purpose of the present invention is to provide a method for preparing a sheet body using recycled clothing. This method is not only different from the existing non-woven fabric process, but also has the characteristics of simple process, energy saving and carbon reduction, significantly reduces pollution to the environment, avoids common cotton wool, dust and industrial safety problems in traditional processes, and has significant environmental protection and practical value.

[0005] In order to achieve the above technical objectives and the above technical effects, the present invention discloses a method for preparing a sheet using recycled clothing, which at least comprises the following steps:

[0006] Synchronous mixing and heating: The recycled garments are broken into crumbs and fiber filaments by repeated tearing and mixing, and are heated synchronously at a predetermined temperature to partially soften the garment crumbs and fiber filaments. The recycled garments do not contain metal accessories, and the predetermined temperature is the softening temperature of some materials of the recycled garments.

[0007] Adjusting the softening state: adding predetermined recycled materials that are softenable or non-softenable at the predetermined temperature according to the softening state of the garment scraps and fiber filaments, so that the recycled materials are repeatedly torn and heated to be mixed with the garment scraps and fiber filaments in a partially softened state;

[0008] When the softened proportion of garment scraps and fiber filaments is greater than the unsoftened proportion, a predetermined proportion of non-softenable recycled materials is added; when the unsoftened proportion of garment scraps and fiber filaments is greater than the softened proportion, a predetermined proportion of softenable recycled materials is added, and the recycled materials are polymer material waste; and

[0009] Cold pressing: A mixture of partially softened garments, recycled material scraps and fiber filaments is pressed into sheets for output. The pressing process is accompanied by simultaneous cooling to obtain a sheet with a majority of fiber filaments.

[0010] Preferably, the steps of "simultaneous mixing and heating" and "adjusting the softening state" are carried out in a closed space.

[0011] Preferably, the steps of "simultaneous mixing and heating" and "adjusting the softening state" are performed in a semi-open space.

[0012] The enclosed space is a cylinder, which is open on the top, and has two heating elements and a plurality of breaking elements arranged inside the cylinder;

[0013] It also includes an extrusion member, which is movably arranged at the top opening of the cylinder body. The two heating members rotate relative to each other and are arranged at an appropriate distance, so that the clothing scraps, fiber filaments and recycled materials pass through the two heating members and are squeezed. The breaking and pulling members are arranged on the outside of the two heating members at an appropriate distance. The extrusion member reciprocates to apply pressure to and release pressure on the clothing scraps, fiber filaments and recycled materials, so that the clothing scraps, fiber filaments and recycled materials are continuously torn and pulled by the breaking and pulling members and the two heating members, and then continuously input between the two heating members to be squeezed and output, and enter between each breaking and pulling member and the two members.

[0014] Among them, in the step of "adjusting the softening state", at the predetermined temperature, by adjusting the addition ratio of the softenable or non-softenable recycled materials, the softened and unsoftened garment scraps and fiber filaments are made to approach the same ratio.

[0015] Wherein, at the predetermined temperature, the recyclable materials that can be softened include PE, PVB and / or EVA polymer waste materials, and at the predetermined temperature, the recyclable materials that cannot be softened include cotton, nylon and / or PET polymer waste materials.

[0016] Preferably, in the "cold pressing" step, the partially softened mixture of garment scraps, fiber filaments and recycled materials is pressed into sheets and output by a tablet press, and the pressing part of the tablet press is in low-temperature contact with the mixture of garment scraps, fiber filaments and recycled materials.

[0017] Among them, most of the prepared fiber filament sheets are non-woven fabrics.

[0018] In addition, the present invention also discloses a mixing and pulling device used in a method for preparing a sheet body using recycled ready-made clothes, wherein the device is used in the above-mentioned steps of "synchronous mixing and pulling and heating" and "adjusting the softening state", and comprises:

[0019] The cylinder is open on the top side and is used to contain ready-made clothes and recycled materials;

[0020] Two heating elements are rotatably disposed opposite to each other in the cylinder body, and the finished clothes and the recycled materials passing therebetween are pressed and heated relative to each other;

[0021] A plurality of tearing members are arranged at appropriate intervals outside the two heating members, each of which is provided with an action surface, and the action surface is inclined relative to the surfaces of the two heating members, so that the garments and recycled materials passing between each tearing member and the two heating members are torn; and

[0022] The extrusion member is reciprocatingly arranged at the top opening of the cylinder body, and its moving direction corresponds to the tearing member and the two heating members. It can reciprocately apply pressure and release pressure on the scraps and fibers of the garments and the recycled materials, so that the garments and the recycled materials are continuously torn by the tearing members and the two heating members, and then continuously input between the two heating members to be extruded and output, and enter between the tearing members and the two heating members, thereby promoting uniform mixing of partially softened garment scraps, fiber filaments and recycled materials.

[0023] Furthermore, the present invention also discloses a mixing and pulling device used in a method for preparing a sheet body using recycled garments, wherein the device is used in the steps of "simultaneous mixing and heating" and "adjusting the softening state", and comprises:

[0024] A conveying device, wherein the conveying device comprises a tube body, the semi-open space is the interior of the tube body, the recovered garments are input from one end of the conveying device, and the garment scraps and fiber filaments are output from the other end of the conveying device;

[0025] A plurality of tearing and pulling members, which are arranged in the tube body and tear the recycled clothes and the softable or non-softenable recycled materials into fragments and fiber filaments;

[0026] A plurality of heating elements, which are arranged in the tube body and heat the passing garments, recycled material scraps, and fiber filaments at different temperatures; and

The present invention has the following beneficial effects:

[0028] The present invention provides a method for preparing a sheet using recycled clothing, which has significant environmental protection and practical value. Compared with the traditional non-woven fabric process, the present method simplifies the production steps, and effectively avoids environmental pollution problems such as cotton wool and dust generated in traditional processes through synchronous mixing and heating, adjusting the softening state and cold pressing steps. In addition, the present method is carried out in a closed or semi-open space, which reduces pollution to the surrounding environment and achieves the effect of energy saving and carbon reduction. Since the clothing scraps and fiber filaments are mixed with the recycled materials in a partially softened state, the sheet finally prepared has good physical properties and can be used in a variety of application scenarios, replacing traditional materials and promoting the resource utilization of waste.

In particular, the design of the equipment allows the softening and mixing of materials in a controlled environment, reducing the health risks to operators and the pollution to the environment. In addition, the softening state of the material can be easily monitored through the inspection window to ensure the stability of the production process and the consistency of product quality. The application of this equipment not only improves the efficiency of waste recycling, but also promotes the development of sustainable production methods. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments.

[0034] Example 1

[0035] like Figure 1 , 2 As shown, the present invention discloses a method 100 for preparing a sheet body by using recycled clothing, wherein the prepared sheet body is a non-woven fabric, and comprises the following steps:

[0036] The first step is synchronous mixing and heating 110: the recycled garments are placed in a closed space, and the recycled garments are broken into debris and fiber filaments by repeated rolling, tearing and mixing, and are heated synchronously at a predetermined temperature to make the garment debris and fiber filaments partially softened. The recycled garments do not contain metal accessories, and the temperature is the temperature at which part of the garment material can be softened. Specifically, the synchronous mixing and heating 110 is implemented using a closed mixing and heating device 10, which includes a cylinder 12, two heating elements 13, 14, a plurality of breaking and pulling elements 15 and an extrusion element 16.

[0037] The cylinder 12 is open at the top and is used to contain the garments, which are recycled garments without metal accessories, including the garment body and buttons, plastic zippers, labels, collar films, linings, GORE-TEX waterproof and breathable membranes, non-removable leather garments and other polymer material accessories.

[0038] The two heating action members 13, 14 are rotatably arranged (the rotation directions are the same or opposite, depending on the material characteristics of the finished clothes or the difficulty of crushing and grinding) relative to each other in the cylinder body 12 and connected to an electric heating device (not shown in the figure), and are composed of a shaft 22 and an action part 24. The two ends of each shaft 22 are mounted on both sides of the cylinder body 12, and one end of each shaft 22 is connected to a power driving device (such as a motor, not shown in the figure) to be driven by the power driving device to rotate, so that the finished clothes passing between the two can be squeezed and heated.

[0039] A plurality of tearing and pulling members 15 are blocks with irregular cross sections, which are arranged at appropriate intervals outside the two heating elements 13 and 14 in the cylinder body 12, so that the garments can be torn by the cooperation between each tearing and pulling member 15 and the two heating elements 13 and 14 when passing between the two tearing and pulling members. Each tearing and pulling member 15 has an action surface 26 corresponding to one of the two heating elements 13 and 14, and each action surface 26 is inclined relative to the surface of the two heating elements 13 and 14, but is not limited thereto, so that the gap between each action surface 26 and the surface of the two heating elements 13 and 14 is from large to small or from small to large (a tearing and drawing effect can be produced when the gap is from large to small, and a mixing effect can be produced when the gap is from small to large).

[0040] The extrusion member 16 is a piston-type, which is driven by a hydraulic cylinder or a pneumatic cylinder and can be reciprocated up and down and is arranged at the top side opening of the cylinder body 12 (the moving stroke can be adjusted so as not to touch the breaking member 15). The first extrusion member 16 moves up and down and corresponds to the gap position between the two working members 13 and 14 to reciprocate and release pressure on the scraps and fibers of the finished garments, thereby promoting the scraps and fibers of the finished garments to flip in the cylinder body 12, and making the finished garments and the scraps and fibers of the finished garments continuously pass through the working surface 26 of each breaking member 15 and the two heating working members 13 and 14 to be torn or mixed, and then continuously input into the two heating working members 13 and 14 to be squeezed and output, and enter between each breaking member 15 and the two heating working members 13 and 14, thereby promoting the uniform mixing of the partially softened scraps and fibers of the finished garments.

[0041] Of course, the mixing and pulling device 10 is not limited to the top side of the cylinder 12, and the bottom side or / and the left and right sides of the cylinder 12 can also be provided with extrusion members 16 to enhance the effect of the garment being crushed, drawn and mixed. In addition, a discharge port (not shown) is further provided at the bottom side of the cylinder 12 to take out the garment scraps and fiber filaments in a partially softened state.

[0042] Since the material of the garment body is mostly plastic material such as polyester fiber or cotton, and the garment body components or accessories are also various plastic materials, the aforementioned temperature refers to a temperature higher than the softening temperature of the garment body and the garment body components and accessories, which is between the thermal deformation temperature and the melting point. In this embodiment, the temperature can be set to 120 degrees Celsius, which is the temperature at which most types of plastic materials have softened (thermal deformation) but not melted (the temperature has not reached the melting point), which can make the recycled debris and fiber filaments partially softened for subsequent processing. Similarly, the setting and adjustment of the temperature can be increased or decreased according to the different components of the recycled garments.

[0043] In other words, in the synchronous mixing, drawing and heating 110 step, the multiple steps of garment crushing, drawing, cotton thinning and cotton sorting in the process of traditional garment recycling into non-woven fabrics can be integrated into one step.

[0044] The second step is to adjust the softening state 120: according to the softening state of the garment scraps and fiber filaments, predetermined recycled materials that can be softened or not at the temperature are added into the space, so that the recycled materials can be repeatedly crushed, torn and heated, and mixed with the garment scraps and fiber filaments in a partially softened state.

[0045] When the softened proportion of garment scraps and fiber filaments is greater than the unsoftened proportion, a predetermined proportion of non-softenable recycled materials is added; when the unsoftened proportion of garment scraps and fiber filaments is greater than the softened proportion, a predetermined proportion of softenable recycled materials is added. The recycled materials are polymer waste materials, such as PE, PVB, EVA, cotton, nylon, PET and other polymer waste materials, but not limited thereto. The proportion of softenable or non-softenable recycled materials added at this temperature is to make the softened and unsoftened garment scraps and fiber filaments approach the same proportion, but not limited thereto.

[0046] Furthermore, in order to enable the subsequent steps to produce non-woven fabrics with a large number of fiber filaments. Therefore, it is necessary to make adjustments based on the partial softening state of the garment scraps and fiber filaments produced by the synchronous mixing and heating 110 steps. For example, when the softened ratio and the unsoftened ratio of garment scraps and fiber filaments are close to the same (about 50% each), this is the best ratio for the subsequent steps to produce non-woven fabrics (with approximately equal amounts of fibers and bonding fiber parts), and there is no need to adjust the partial softening state of garment scraps and fiber filaments. When the softened ratio of garment scraps and fiber filaments is about 30% and the unsoftened ratio is about 70%, it means that the unsoftened ratio is too high, which will result in the non-woven fabric produced in the subsequent steps having too many fibers and too few bonding fiber parts, and the structure of the non-woven fabric will be too loose and easy to break.

[0047] At this time, 20% to 40% of recycled materials that can be softened at this temperature (such as the aforementioned PE, PVB, EVA, etc., which can be softened or melted at 120 degrees Celsius) can be added to the mixing and pulling equipment 10 for tearing and mixing, so that the softened and unsoftened ratios of the finished garments and the recycled material scraps and fiber filaments mixture can be close to equal.

[0048] When the softened proportion of the garment scraps and fiber filaments is about 80% and the unsoftened proportion is about 20%, it means that the softened proportion is too high, which will result in the non-woven fabric made in the subsequent steps having too few fiber parts and too many bonded fiber parts, and not like a non-woven fabric. At this time, 30% to 50% of the recycled materials that cannot be softened at this temperature (such as the aforementioned cotton, nylon and PET, which have not softened at 120 degrees Celsius) can be added to the closed mixing and pulling device 10 for tearing and mixing, so that the softened and unsoftened proportions of the mixture of garment and recycled material scraps and fiber filaments can be close to equal.

[0049] The last step is cold pressing 130: the mixture of the garments and the recycled material scraps and filaments after the softening state is taken out from the mixing and pulling device 10, and is pressed into a sheet by a tablet press (not shown in the figure) and cooled synchronously during the pressing process to obtain a sheet with a majority of filaments, i.e., a non-woven fabric. The tablet press is a type with two rollers, and the pressure application part is the two rollers. The partially softened garment scraps, filaments and the mixture of recycled materials are input between the two rollers and pressed out. The two rollers are connected to a low-temperature cooling device (not shown in the figure, and its technology is the same as the known connection electric heating device, which belongs to the known technology and will not be repeated here), which is used to cool and shape the mixture of the garments and the recycled material scraps and filaments when they are pressed into sheets, so as to obtain a non-woven fabric with uniform quality, which can replace the steps of cotton thinning, needle punching, etc. in the traditional process of recycling garments into non-woven fabrics.

[0050] The method for preparing a sheet body by utilizing recycled garments of the present invention, through the steps of synchronous mixing and pulling, heating, adjusting the softening state and cold pressing, is not only different from the traditional process of recycling garments into non-woven fabrics, but also has consistent quality, simple process, can achieve energy-saving and carbon reduction effects, and can manufacture non-woven fabrics in a closed circulation environment, greatly reducing pollution to the surrounding environment, and is free of the very polluting cotton wool, dust and work safety management problems in the traditional process of recycling garments into non-woven fabrics, and has significant environmental protection and practical value.

[0051] Example 2

[0052] like Figure 3 As shown, it is another preferred embodiment of the present invention, and its steps are roughly the same as the preparation method disclosed in Example 1, except that:

[0053] In the method 100 for preparing a sheet using recycled garments, the synchronous mixing and heating step 110 and the softening state adjustment step 120 are performed in a semi-open space, such as Figure 3 Another mixing and pulling device 30 is shown. The mixing and pulling device 30 also includes the aforementioned breaking and pulling member 15 , but the difference is that it includes a conveying device 32 , a plurality of heating elements (not shown) and a plurality of inspection windows 34 .

[0054] The conveying device 32 includes a tube body 40, the interior of which forms a semi-open space, and the recycled clothes are input from one end of the tube body 40 and output from the other end. The conveying device 32 can be a known screw conveyor with a conveying screw inside, but is not limited thereto, as long as it can move and output the recycled clothes. Each tearing piece 15 is arranged in the tube body 40, and when the recycled clothes are moved by the conveying device 32, they can be torn into fragments and fiber filaments through these tearing pieces 15.

[0055] Several heating elements are arranged at different positions on the inner wall of the tube 40, and can heat the garments, recycled material scraps, and fiber filaments passing through the corresponding positions of different heating elements at different temperatures. These heating elements are roughly similar to the heating devices in the known tunnel-type rubber foaming ovens and baking ovens, and belong to the known technology, which will not be described in detail here.

[0056] Several inspection windows 34, which are composed of an openable and closable window frame and a piece of glass (not shown), are openably arranged on the top side of the tube body 40, and can be used to observe the softening status of the garment scraps and fiber filaments at different positions in the tube body 40, and can be opened to put in the recyclable materials that can be softened or not. These inspection windows 34 are roughly similar to the inspection windows for inspecting the production status in various production equipments, which belong to the known technology and will not be described in detail here.

[0057] Through the synchronous mixing and heating step 110 and the softening state adjustment step 120, when the mixing and pulling device 30 is used, the recycled garments are input into the conveying device 32 from one end of the tube body 40, and the recycled garments can be repeatedly torn into fragments and fiber filaments by the various tearing and pulling parts 15 inside the conveying device 32 during movement, and are heated by the various heating parts at the same time, so that the garment fragments and fiber filaments are partially softened. The staff can inspect the softening state of the garment fragments and fiber filaments in the conveying device 32 through the various inspection windows 34, and can put the predetermined softenable or non-softenable recycled materials into the conveying device 32 through these inspection windows 34.

[0058] In addition, the number of each tearing and pulling member 15 is gradually reduced from the recycled clothing input end of the tube body 40 to the other end, so as to ensure that the recycled clothing can be completely broken into debris and fiber filaments. Secondly, the heating temperature of each heating element is gradually increased from the recycled clothing input end of the tube body 40 to the other end, that is, the heating temperature of the heating element close to the recycled clothing input end of the tube body 40 is relatively low (for example, 50 degrees Celsius), while the heating temperature of each heating element arranged toward the other end of the tube body 40 is gradually increased (for example, the heating temperature of the heating element on the top side of the inner wall of the tube body 40 can be increased from 120 degrees Celsius to 180 degrees Celsius, and the heating temperature of the heating element on the bottom side of the inner wall of the tube body 40 can be increased from 120 degrees Celsius to 250 degrees Celsius, but not limited to this).

[0059] Furthermore, a plurality of monitoring devices, such as monitoring lenses or pressure sensing components, may be provided in the tube body 40 to monitor the softening state of the garment scraps and fiber filaments at different positions in the tube body 40 using these monitoring lenses or pressure sensing components (when the scraps and fiber filaments of recycled garments and recycled materials are softened, the pressure value monitored by the pressure sensing component is low, thereby judging that the scraps and fiber filaments of recycled garments and recycled materials have been softened; conversely, a high pressure value indicates that the scraps and fiber filaments of recycled garments and recycled materials have not been softened or have mostly not been softened).

[0060] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
