[0003] However, the existing process causes significant pollution to the environment, including the generation of a large amount of cotton flock, dust, and problems of industrial safety and health management. In addition, the process itself is complex and inefficient. Although recycling clothes for reuse has environmental significance, the environmental impact and efficiency problems in the actual production process indicate that the existing technology needs to be improved. In the current social background of increasing concern about carbon emissions and sustainable development, it is particularly important to develop a more environmentally friendly and efficient technology for recycling clothes.

[0015] Wherein, in the step of "adjusting the softening state", at the predetermined temperature, by adjusting the adding proportion of the softenable or non-softenable recycled material, the softened and unsoftened clothing scraps and fiber filaments tend to have the same proportion.

[0034] In order to make the purpose, technical solutions and advantages of the present application clearer and more apparent, the present application will be further described in detail below with reference to the embodiments.

[0035] Example 1

[0036] As shown in Figures 1 and 2, the present application discloses a method 100 for preparing a sheet body from recycled clothing, and the prepared sheet body is a non-woven fabric, comprising the following steps:

[0037] The first step is to synchronize the mixing and heating 110: the recycled clothes are placed in a closed space, and through repeated crushing and tearing and mixing, the recycled clothes are broken into pieces and fiber filaments, and are synchronously heated to a predetermined temperature, so that the clothes pieces and fiber filaments are in a partially softened state. The recycled clothes do not contain metal parts. The temperature is the temperature at which the clothes can be partially softened. Specifically, the synchronization mixing and heating 110 is implemented using a closed mixing and tearing device 10, which includes a cylinder 12, two heating elements 13, 14, a plurality of tearing elements 15, and a pressing element 16.

[0038] The cylinder 12 is open at the top and is used to contain clothes that do not contain metal parts, including clothes and buttons, plastic zippers, labels, collar tapes, linings, GORE-TEX waterproof and breathable membranes, and high-molecular material accessories such as unopened leather jackets.

[0039] The two heating elements 13, 14 are rotatably (the rotation direction can be the same or opposite, depending on the material properties of the clothes or the difficulty of crushing and grinding) disposed in the cylinder 12 and connected to an electric heating device (not shown in the figure), composed of a shaft 22 and an action part 24. Each shaft 22 is supported at both ends of the cylinder 12, and one end of each shaft 22 is connected to a power drive device (such as a motor, not shown in the figure) to be driven by the power drive device to rotate, so that the clothes passing between the two can be squeezed and heated.

[0040] The tearing elements 15 are irregularly shaped blocks with appropriate spacing between the two heating elements 13, 14 on the outside of the cylinder 12, so that the clothes passing between each tearing element 15 and the two heating elements 13, 14 are torn by the combined action of the two. Each tearing element 15 has an action surface 26 corresponding to one of the two heating elements 13, 14. Each action surface 26 is inclined relative to the surface of the two heating elements 13, 14, but is not limited to this, so that the gap between each action surface 26 and the surface of the two heating elements 13, 14 is from large to small or from small to large (a large gap can produce tearing and filamentation, while a small gap can produce mixing).

[0041] The extrusion member 16 is in the form of a piston and is driven by an oil or air cylinder to reciprocate up and down in the top opening of the cylinder 12 (the stroke is adjustable to the extent that the puller 15 is not touched). The first extrusion member 16 reciprocates up and down and corresponds to the gap position of the two acting members 13, 14 to push and release the pressure of the clothing scraps and fibers, promote the clothing scraps and fibers to turn in the cylinder 12, and make the clothing and the clothing scraps and fibers continuously pass through the acting surface 26 of each puller 15 and between the two heating acting members 13, 14 to be torn or mixed, and then continuously input between the two heating acting members 13, 14 to be extruded and output, and enter between the puller 15 and the two heating acting members 13, 14 to promote the uniform mixing of the partially softened clothing scraps and fibers.

[0042] Of course, the mixed tearing device 10 is not limited to the extrusion member 16 arranged on the top side of the cylinder 12. The bottom side and / or the left and right sides of the cylinder 12 can also be provided with extrusion members 16 to improve the effect of clothing being broken, torn and mixed. In addition, the bottom side of the cylinder 12 is further provided with a discharge port (not shown) to take out the clothing scraps and fiber filaments in a partially softened state.

[0043] Since the clothing body material of the clothing is mostly polyester fiber or plastic material or cotton, and the clothing body member or accessory is also various plastic materials, the aforementioned temperature refers to a temperature higher than the softening temperature of the clothing body and the clothing body member or accessory material, between the heat 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 material have softened (heat deformation) but not melted (temperature not reaching the melting point). The recycled clothing scraps and fiber filaments are in a partially softened state to facilitate subsequent processing. Similarly, the setting and adjustment of the temperature can be increased or decreased according to the different components of the recycled clothing.

[0044] In other words, in the synchronous mixed tearing and heating 110 step, the clothing breaking, tearing, cotton loosening, and cotton integration steps in the process of recycling conventional clothing into non-woven fabric can be integrated into one step.

[0045] The second step is to adjust the softening state 120: according to the softening state of the clothing scraps and fiber filaments, add predetermined recycled materials that can or cannot be softened at this temperature to the space, so that the recycled materials can be repeatedly crushed, torn and heated, and mixed with the clothing scraps and fiber filaments in a partially softened state.

[0046] When the softened proportion of the clothing scraps and fiber filaments is greater than the unsoftened proportion, a predetermined proportion of the non-softenable recycled material is added; when the unsoftened proportion of the clothing scraps and fiber filaments is greater than the softened proportion, a predetermined proportion of the softenable recycled material is added. The recycled material is a polymer material waste, such as PE, PVB, EVA, cotton, nylon and PET, but is not limited thereto. The added proportion of the softenable or non-softenable recycled material at the temperature is such that the softened and unsoftened clothing scraps and fiber filaments are close to the same proportion, but is not limited thereto.

[0047] Further, in order to enable the subsequent step to produce the non-woven fabric with a plurality of fiber filaments, the partial softening state of the clothing scraps and fiber filaments generated by the simultaneous tearing and mixing and heating step 110 needs to be adjusted. For example, when the softened proportion and the unsoftened proportion of the clothing scraps and fiber filaments are close to each other (about 50% each), which is the optimal proportion for the subsequent step to produce the non-woven fabric (with about equal amounts of fiber and bonding fiber parts), the partial softening state of the clothing scraps and fiber filaments does not need to be adjusted. When the softened proportion of the clothing scraps and fiber filaments is about 30% or so and the unsoftened proportion is about 70% or so, it indicates that the unsoftened proportion is too high, which will result in the non-woven fabric produced in the subsequent step having too many fiber parts and too few bonding fiber parts, and the structure of the non-woven fabric will be too loose and easy to break.

[0048] At this time, 20% to 40% of the softenable recycled material at the temperature (such as PE, PVB, EVA, etc. as mentioned above, which can be softened or melted at 120 degrees Celsius) can be added to the tearing and mixing device 10 for tearing and mixing, so that the softened and unsoftened proportions of the clothing and recycled material scrap and fiber filament mixture can be close to each other.

[0049] When the softened proportion of the clothing scraps and fiber filaments is about 80% or so and the unsoftened proportion is about 20% or so, it indicates that the softened proportion is too high, which will result in the non-woven fabric produced in the subsequent step having too few fiber parts and too many bonding fiber parts, and not like a non-woven fabric. At this time, 30% to 50% of the non-softenable recycled material at the temperature (such as cotton, nylon and PET, etc. as mentioned above, which has not been softened at 120 degrees Celsius) can be added to the closed tearing and mixing device 10 for tearing and mixing, so that the softened and unsoftened proportions of the clothing and recycled material scrap and fiber filament mixture can be close to each other.

[0050] The last step is cold pressing 130: the mixture of the aforementioned adjusted softened state of the clothes and the recycled material chips, fiber filaments is taken out from the mixing and drawing device 10, and is pressed into a sheet shape by a sheet press (not shown in the figure) to be output. The pressing process is synchronized with cooling to obtain a sheet body with a plurality of fiber filaments, i.e. a non-woven fabric. The sheet press is of a type with two rollers, and the pressing part is the two rollers. The partially softened clothes chips, fiber filaments and recycled material mixture is input between the two rollers to be pressed out. The two rollers are connected to a low-temperature cooling device (not shown in the figure, which is known to be connected to an electric heating device and belongs to the known technology, which will not be described here), which is used to cool and shape the clothes and recycled material chip and fiber filament mixture simultaneously when it is pressed into a sheet shape to obtain a non-woven fabric with uniform quality, which can replace the traditional steps of fluffy cotton and needling in the process of recycling clothes into non-woven fabric.

[0051] The method for preparing a sheet body from recycled clothes according to the present application, by synchronously mixing and drawing and heating, adjusting the softening state and cold pressing steps, not only differs from the traditional process of recycling clothes into non-woven fabric, but also has uniform quality, simple process, energy saving and carbon reduction effect, and can manufacture non-woven fabric in a closed cycle environment, greatly reducing the pollution to the surrounding environment, and has no fluffy cotton, dust and work safety management problems in the traditional process of recycling clothes into non-woven fabric, which has significant environmental protection and practical value.

[0052] Example 2

[0053] As shown in FIG. 3, another preferred embodiment of the present application has substantially the same preparation method as disclosed in Example 1, except that:

[0054] In this embodiment, the method 100 for preparing a sheet body from recycled clothes synchronously mixes and draws and heats step 110 and adjusts the softening state step 120 in a semi-open space, such as another mixing and drawing device 30 shown in FIG. 3. The mixing and drawing device 30 also includes the aforementioned breaking and drawing members 15, but differs in that it includes a conveying device 32, a plurality of heating members (not shown in the figure) and a plurality of viewing windows 34.

[0055] The conveying device 32 includes a pipe body 40, which forms a semi-open space inside, and the recycled clothes are input from one end of the pipe 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 breaking and drawing member 15 is arranged in the pipe body 40, and when the recycled clothes are moved by the conveying device 32, they can pass through the breaking and drawing members 15 to be torn and drawn into chips and fiber filaments.

[0056] The several heating elements are arranged at different positions of the inner wall of the tube 40, and can heat the clothes, the recycled material chips and the fiber filaments at different temperatures when passing through the corresponding positions of the heating elements. The heating elements are substantially similar to the heating devices in the known tunnel type rubber foaming oven and oven, which are known in the art and will not be described in detail here.

[0057] The several inspection windows 34 are formed by a window frame and a glass (not shown in the figure), and are arranged on the top side of the tube 40 in an openable manner. The inspection windows 34 can be used to observe the softening state of the clothes chips and fiber filaments at different positions in the tube 40, and can be opened to put the recycled materials that can or cannot be softened.

[0058] By synchronizing the mixing and pulling step 110 and the softening state adjusting step 120, when the mixing and pulling device 30 is used, the recycled clothes are input into the conveying device 32 from one end of the tube 40. The recycled clothes can be repeatedly torn into chips and fiber filaments by each tearing and pulling element 15 inside the conveying device 32 during movement, and are simultaneously heated by each heating element, so that the clothes chips and fiber filaments are in a partially softened state. The workers can observe the softening state of the clothes chips and fiber filaments in the conveying device 32 through the several inspection windows 34, and can put the predetermined recycled materials that can or cannot be softened into the conveying device 32 through the inspection windows 34.

[0059] In addition, the number of each tearing and pulling element 15 gradually decreases from the input end of the recycled clothes in the tube 40 to the other end, so as to ensure that the recycled clothes can be completely destroyed into chips and fiber filaments. Secondly, the heating temperature of each heating element gradually increases from the input end of the recycled clothes in the tube 40 to the other end, that is, the heating temperature of the heating element near the input end of the recycled clothes in the tube 40 is low (for example, 50 degrees Celsius), and the heating temperature of each heating element arranged towards the other end of the tube 40 gradually increases (for example, the heating temperature of the heating element on the top side of the inner wall of the tube 40 can increase 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 40 can increase from 120 degrees Celsius to 250 degrees Celsius, but not limited thereto).

[0060] Furthermore, a plurality of monitoring devices, such as monitoring lenses or pressure sensing components, can be arranged in the tube 40. The softening state of the clothes chips and fiber filaments at different positions in the tube 40 can be monitored by using the monitoring lenses or pressure sensing components (when the recycled clothes and the chips and fiber filaments of the recycled materials are softened, the pressure value monitored by the pressure sensing component is low, and it can be judged that the recycled clothes and the chips and fiber filaments of the recycled materials have been softened; on the contrary, the pressure value is high, which indicates that the recycled clothes and the chips and fiber filaments of the recycled materials are not softened or most of them are not softened).

[0061] The above description is only the preferred embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
