Description

Technical Field

[0001] This invention belongs to the field of sports equipment manufacturing technology, and in particular relates to a washable paper fiber environmentally friendly shoe leather, its manufacturing method and application. Background Technology

[0002] Currently, the main material used in shoe leather is synthetic leather. Synthetic leather is mostly made by foaming or coating different formulations such as PVC or PU onto woven or non-woven fabric substrates.

[0003] To achieve the high strength and wear resistance of animal leather, chemical binders that enhance fiber bonding are added to modify the woven or non-woven fabric substrate. Then, the substrate is dyed using vat dyeing or tank dyeing, and finally, the substrate is finished to form artificial leather with strength, color, and feel similar to genuine leather.

[0004] The aforementioned traditional artificial leather manufacturing process uses woven or non-woven fabrics as raw materials, both of which are generally chemical fiber fabrics, resulting in low environmental friendliness during production. The chemical adhesives used to enhance fiber bonding strength further increase the content of organic chemical components in the artificial leather, reducing the product's environmental friendliness. When dyeing the base material, vat dyeing or tank dyeing methods suitable for woven or non-woven fabric base materials are selected, resulting in long dyeing times. Generally, the entire dyeing process requires at least 5 hours, and each ton of product typically consumes no less than 8 tons of water. This process is time-consuming, water-intensive, and has very high production costs.

[0005] Furthermore, leather made using traditional techniques has many limitations when used in shoes. For example, it is prone to cracking after washing, cannot be dry cleaned, is easily damaged by rubbing after soaking, is easily torn when torn, has poor plasticity, is not easy to form texture, is easily torn when combined with various metal accessories, and has poor durability when sewn with other fabrics.

[0006] Therefore, the industry urgently needs to develop a substitute for current synthetic leather for use in shoes. Summary of the Invention

[0007] The purpose of this invention is to provide a washable paper fiber environmentally friendly shoe leather, its manufacturing method and application, so as to at least solve the problems of the prior art mentioned above.

[0008] To achieve the above objectives, this invention provides a method for manufacturing washable paper fiber environmentally friendly shoe leather, comprising the following steps:

[0009] S100: Pulping treatment, providing plant fibers and decomposing them, then adding hydrophobic agents and modifiers to the decomposed plant fibers;

[0010] S200: Pressing process, which involves pressing pulped plant fibers to remove moisture;

[0011] S300: Drying process, evaporating the moisture from the pressed plant fibers to dry them;

[0012] S400: Surface treatment, embossing and color fixing of dried plant fibers;

[0013] S500: Cutting process, which involves cutting surface-treated plant fibers to form a shoe leather that conforms to the desired shape.

[0014] Optionally, in step S100, the plant fiber provided for pulping is wood fiber or bamboo fiber.

[0015] Optionally, in step S100, the hydrophobic agent added to the decomposed plant fiber is prepared by mixing 10-15 parts of anhydrous ethanol, 20-25 parts of nano-silica, 20-30 parts of paraffin, 5-10 parts of rosin, and 15-25 parts of amino silicone oil.

[0016] Optionally, in step S100, the modifier is composed of the following raw materials in weight percentages: 50%-70% polyvinyl alcohol, 20%-30% polyethylene fiber, 5%-10% sodium carboxymethyl cellulose, 1%-3% polyoxyethylene alkyl ether, and 4%-8% starch.

[0021] A receiving screen is disposed in the pressing chamber and located below the roller pressing device, and the receiving screen extends to the discharge port;

[0022] A moisture collection tank is located below the water outlet.

[0023] Optionally, the roller pressing device includes a front pressure roller, a rear pressure roller, a top pressure roller, and a hydraulic drive mechanism. The front pressure roller, the top pressure roller, and the rear pressure roller are all rotatably mounted on the frame and are driven in conjunction with each other by the hydraulic drive mechanism. A first pressing gap is formed between the top pressure roller and the front pressure roller, facing the feed inlet. A second pressing gap is formed between the top pressure roller and the rear pressure roller, facing the discharge outlet. The distance of the second pressing gap is smaller than the distance of the first pressing gap.

[0024] Optionally, the spacing of the first pressing gap is between 5mm and 8mm, the spacing of the second pressing gap is between 1mm and 4mm, and the ratio of the spacing of the first pressing gap to the spacing of the second pressing gap is between 4 and 1.5.

[0025] Optionally, the hydraulic drive mechanism includes a front hydraulic motor, a rear hydraulic motor, and a gear set. The front hydraulic motor is drivenly connected to the first end of the front pressure roller, the rear hydraulic motor is drivenly connected to the second end of the rear pressure roller, and the gear set is simultaneously linked to the first ends of both the rear pressure roller and the top pressure roller.

[0026] This invention also provides a washable paper fiber environmentally friendly shoe leather, which is manufactured using the above-described manufacturing method.

[0027] The present invention provides the application of washable paper fiber environmentally friendly shoe leather in the upper, tongue, and eyelet of shoes.

[0059] Example 1.

[0060] In this embodiment, as Figure 1 As shown, a method for manufacturing washable paper fiber environmentally friendly shoe leather is provided, including the following steps:

[0061] S100: Pulping treatment, providing plant fibers and decomposing them, then adding hydrophobic agents and modifiers to the decomposed plant fibers; wherein, .

[0062] S200: Pressing process, which involves pressing pulped plant fibers to remove moisture;

[0063] S300: Drying process, evaporating the moisture from the pressed plant fibers to dry them;

[0064] S400: Surface treatment, which involves embossing and color fixing of dried plant fibers; because it is a plant fiber, the dyeing speed is faster than that of traditional leather. Generally, the dyeing time for one ton of plant fiber is only 2 hours, and the water consumption is only 3 tons, which greatly reduces the production and processing cost.

[0065] S500: Cutting process, which involves cutting surface-treated plant fibers to form a shoe leather that conforms to the desired shape.

[0066] Combination Figure 9-18 As shown, the method of this invention produces washable paper fiber environmentally friendly shoe leather, which has the advantages of being environmentally friendly, washable and dry-cleanable, not tearable after soaking and rubbing, not tearable even with strong tearing, highly malleable and already textured, easy to attach various metal accessories, and can be firmly sewn together with other fabrics.

[0067] Furthermore, in step S100, the plant fiber provided for pulping is wood fiber or bamboo fiber. Both wood fiber and bamboo fiber used in this embodiment are environmentally friendly materials and are readily available.

[0068] Further, in step S100, the hydrophobic agent added to the decomposed plant fibers is prepared by mixing 10 parts anhydrous ethanol, 20 parts nano-silica, 20 parts paraffin, 5 parts rosin, and 15 parts amino silicone oil. In this embodiment, the hydrophobic agent formulated with this method can form a cured film on the surface of the shoe leather. This cured film can isolate water penetration, giving the shoe leather excellent hydrophobic properties and playing a role in water repellency and moisture protection.

[0069] Furthermore, in step S200, a roller press 1000 is used to press the pulped plant fibers. Specifically, the roller press 1000 has a better pressing effect on the plant fibers, can more fully remove the moisture from the plant fibers, which is beneficial for the subsequent drying of the plant fibers, and the connection and transition between each process step is better.

[0070] In this embodiment, combined with Figure 2-7 As shown, the roller press 1000 includes a frame 10, a roller pressing device 20, a receiving screen 30, and a moisture collection tank 40.

[0071] The frame 10 includes a pressing chamber 11. A feed inlet 12 communicating with the pressing chamber 11 is located on the upper front side of the frame 10, and a discharge outlet 13 communicating with the pressing chamber 11 is located on the lower rear side of the frame 10. A water outlet 111 is located at the bottom of the pressing chamber 11. During operation, plant fiber material enters the pressing chamber 11 through the feed inlet 12, is pressed, and then discharged through the discharge outlet 13 for collection.

[0072] The roller press device 20 passes through the pressing chamber 11 and is mounted on the frame 10 for pressing plant fibers. The roller press device 20 uses the squeezing between rollers to press and remove moisture from the plant fibers, which is more effective than centrifugal pressing.

[0073] The receiving sieve 30 is disposed within the pressing chamber 11 and located below the roller pressing device 20, extending to the discharge port 13. Specifically, the receiving sieve 30 carries the plant fibers after roller pressing, and moisture can be filtered through it. The plant fibers can then be removed from the discharge port 13, making the operation very convenient.

[0074] The moisture collection tank 40 is located below the water outlet 111. The moisture collection tank 40 is used to collect the moisture extracted by the roller press.

[0075] Furthermore, combined Figure 2 , 3 As shown in Figure 6, the roller pressing device 20 includes a front pressure roller 21, a rear pressure roller 22, a top pressure roller 23, and a hydraulic drive mechanism 24. The front pressure roller 21, the top pressure roller 23, and the rear pressure roller 22 are all rotatably mounted on the frame 10 and are driven in conjunction with each other by the hydraulic drive mechanism 24. A first pressing gap is formed between the top pressure roller 23 and the front pressure roller 21, facing the feed inlet 12. A second pressing gap is formed between the top pressure roller 23 and the rear pressure roller 22, facing the discharge outlet 13. The distance of the second pressing gap is smaller than the distance of the first pressing gap. Specifically, plant fibers enter the pressing chamber 11 from the feed inlet 12, first undergoing pressing through the first pressing gap between the top pressure roller 23 and the front pressure roller 21, and then undergoing pressing through the second pressing gap between the top pressure roller 23 and the rear pressure roller 22. This two-round pressing process ensures more thorough pressing of the plant fibers. Furthermore, the distance between the front pressure roller 21 and the rear pressure roller 22 is shorter than the spacing between the first and second pressing intervals. This minimizes the risk of plant fibers falling through the gap between the front and rear pressure rollers 21 after the first pressing. Preferably, this distance is set to less than 1 mm.

[0076] Furthermore, combining Figure 6As shown, the spacing of the first pressing gap is between 5mm and 8mm, and can be selected as 5mm, 6mm, 7mm, or 8mm; the spacing of the second pressing gap is between 1mm and 4mm, and can be selected as 1mm, 2mm, 3mm, or 4mm; simultaneously, the ratio of the spacing of the first pressing gap to the spacing of the second pressing gap is between 4 and 1.5, that is, the ratio of the spacing of the first pressing gap to the spacing of the second pressing gap needs to be 4, 3, or 1.5, etc. After an infinite number of experiments, this spacing ratio can achieve maximum pressing efficiency in only two pressing operations on the plant fiber, and the pressing efficiency is also high, making it less likely to cause problems such as jamming of the roller pressing device 20, and the practical effect is very good.

[0077] In this embodiment, combined with Figure 4-6 As shown, the hydraulic drive mechanism 24 includes a front hydraulic motor 241, a rear hydraulic motor 242, and a gear set 243. The front hydraulic motor 241 is driven and connected to the first end of the front pressure roller 21, and the rear hydraulic motor 242 is driven and connected to the second end of the rear pressure roller 22. The gear set 243 is simultaneously linked and connected to the first ends of both the rear pressure roller 22 and the top pressure roller 23. In this embodiment, a hydraulic motor is used as the power source, which can provide sufficient and strong torque, enabling efficient roller pressing of plant fibers made from wood fiber or bamboo fiber. Furthermore, this embodiment provides two hydraulic motors, the front hydraulic motor 241 and the rear hydraulic motor 242, as power sources to drive the front pressure roller 21 and the rear pressure roller 22 respectively. Then, the gear set 243 drives the top pressure roller 23 to rotate, thus achieving linkage of the three rollers: the front pressure roller 21, the rear pressure roller 22, and the top pressure roller 23. This effectively performs the first and second pressing of the plant fibers entering the pressing chamber 11.
