[0038] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] A new regenerated superfine fiber material of the present invention comprises the following steps:

[0040] The first step: Raw material preparation, collecting a large number of waste textiles and leather scraps to ensure the diversity and sufficiency of raw materials;

[0041] The second step: Raw material sorting, arranging professional personnel for meticulous sorting to improve the sorting efficiency and accuracy;

[0042] The third step: Crushing and cleaning, selecting appropriate crushing machines and cleaning equipment, and strictly controlling the process parameters;

[0043] The fourth step: Melting and spinning, adjusting the melting temperature and spinning speed according to the characteristics of the raw materials;

[0044] The fifth step: Superfine fiber synthesis and post-treatment, adopting advanced synthesis equipment and post-treatment processes to ensure the product quality.

[0045] In this embodiment, the raw materials: Select waste materials such as waste textiles and leather scraps as the main raw materials.

[0046] In this embodiment, during the raw material sorting process, impurities and non-recyclable parts are removed.

[0047] In this embodiment, during the cleaning process, stains, grease, etc. on the surface of the raw materials are removed.

[0048] In this embodiment, during the melting process of the fourth step, the material becomes a uniform fluid.

[0049] In this embodiment, post-treatment is performed on the material after superfine fiber synthesis, such as dyeing, waterproof treatment, etc.

[0050] In this embodiment, the crushing process in the third step includes the following steps:

[0051] The first step: Raw material pretreatment, preliminarily sorting the collected raw materials such as waste textiles and leather scraps, removing obvious foreign objects, such as metal parts, large pieces of plastic, etc., to prevent these impurities from entering the crushing equipment and causing equipment damage. At the same time, the raw materials are simply classified, such as being distinguished according to the general type of material, thickness, etc., so as to select appropriate crushing parameters for the subsequent process;

[0052] Step 2: Feeding. The pre-treated raw materials are evenly and stably fed into the crushing equipment through the feeding device. When feeding, pay attention to controlling the feeding speed to avoid equipment blockage caused by too fast feeding or affecting production efficiency due to too slow feeding.

[0053] Step 3: Coarse crushing. After the raw materials enter the crusher, they are first coarsely crushed, and the raw materials with larger sizes are crushed into preliminary small pieces or flakes. The main purpose of the coarse crushing stage is to reduce the size of the raw materials to a certain extent to prepare for the subsequent fine crushing. During this process, the cutting tools or hammers of the crushing equipment strike, squeeze or shear the raw materials at a certain rotational speed and force to break the raw materials.

[0054] Step 4: Fine crushing. The raw materials that have undergone coarse crushing enter the fine crushing process to further reduce the particle size and make the raw materials reach a more uniform particle size distribution. Fine crushing usually uses smaller crushing gaps and higher rotational speeds to perform more refined processing on the materials after coarse crushing to meet the requirements of the subsequent process for the particle size of the raw materials.

[0055] Step 5: Discharging and screening. After crushing is completed, the materials are discharged from the discharge port of the crushing equipment. The discharged materials usually pass through a screening device to screen out the crushed materials that meet the specified particle size and enter the next process; the materials that do not meet the particle size requirements are returned to the crushing equipment for re-crushing to ensure that all materials can reach the appropriate particle size.

[0056] Furthermore, the cleaning process in Step 3 includes the following steps:

[0057] Step 1: Preparation of cleaning liquid. According to the characteristics of the raw materials and the type of stains, select a suitable cleaning liquid formula and prepare the cleaning liquid in the cleaning tank according to a certain ratio. For example, if the raw materials are mainly contaminated with oil stains, a cleaning liquid containing an appropriate amount of surfactant and alkaline substances can be prepared; if mainly dust and other impurities, simple clean water or an aqueous solution with a small amount of dispersant added can be prepared.

[0058] Step 2: Loading. The crushed materials with qualified particle size are transported into the cleaning equipment. Usually, a conveyor belt or a lifting device is used to evenly feed the materials into the cleaning tank, cleaning drum or other cleaning equipment.

[0059] Step 3: Soaking. After the materials enter the cleaning equipment, they are first soaked in the cleaning liquid to allow the stains to fully contact the cleaning liquid. Some soluble or easily decomposable stains start to dissolve or be decomposed by the chemical substances in the cleaning liquid during the soaking process. The soaking time depends on the degree of contamination and the material of the raw materials, generally 5 - 15 minutes.

[0060] Step 4: Stirring or spraying for cleaning. After soaking for a certain period of time, start the stirring device or spraying system of the cleaning equipment. Stirring can make the cleaning liquid fully mix with the materials, improving the cleaning effect; spraying is to evenly spray the cleaning liquid on the surface of the materials through high-pressure nozzles to wash away the stains. During the stirring or spraying process, parameters such as the stirring speed, spraying pressure, and time should be controlled to ensure the cleaning effect while avoiding damage to the fibers.

[0061] Step 5: Rinsing. After stirring or spraying for cleaning, rinse the materials with clean water to remove the residual cleaning liquid and the stains that have been washed off on the surface of the materials. Rinsing generally needs to be carried out 2 - 3 times, and the rinsing time for each time is 3 - 5 minutes to ensure that the materials are cleaned thoroughly.

[0062] Step 6: Dewatering. After rinsing is completed, dewater the materials to remove the excess water in the materials. The dewatering method can adopt centrifugal dewatering, extrusion dewatering, or vacuum dewatering, etc., to reduce the moisture content of the materials to a certain extent for subsequent processing. The moisture content of the dewatered materials is generally controlled at about 10% - 20%.

[0063] Step 7: Drying. Finally, send the dewatered materials into the drying equipment for drying to completely remove the remaining moisture. The drying temperature and time are adjusted according to the material and characteristics of the materials. Generally, the drying temperature is between 60 - 100 °C, and the drying time is 1 - 3 hours to make the materials reach an appropriate moisture content to meet the requirements of subsequent processes such as melting and spinning.

[0065] This product is woven from regenerated polyester fibers and other fibers, forming a unique fiber network structure, endowing it with high strength and wear resistance.

[0066] This product can be applied not only to shoe materials but also to fields such as automotive interiors, expanding the application scope of regenerated ultra-fine fiber materials.

[0068] This product is woven from regenerated polyester fibers and other fibers, forming a unique fiber network structure, endowing it with high strength and wear resistance.

[0069] Crushing process parameters:

[0070] Selection of Crushing Equipment and Rotation Speed Equipment Type: Different ultra-fine fiber materials have different raw material properties, and appropriate crushing equipment needs to be selected according to the hardness, toughness, etc. of the raw materials. For example, for waste leather scraps with relatively high hardness, a jaw crusher or a cone crusher may be required; for waste textiles with relatively soft texture, a hammer crusher or a roll crusher may be more suitable.

[0071] Rotation Speed: The rotation speed directly affects the crushing effect and efficiency. If the rotation speed is too fast, it may lead to excessive crushing, resulting in too short fiber length and affecting subsequent spinning and ultra-fine fiber synthesis; if the rotation speed is too slow, the crushing efficiency is low and cannot meet the production requirements. Generally speaking, for leather scraps, the rotation speed of the crusher may be 300 - 500 revolutions per minute; for waste textiles, the rotation speed can be 200 - 400 revolutions per minute, and specific adjustments need to be made according to the actual situation of the raw materials.

[0072] Crushing Time If the crushing time is too short, the raw materials cannot be fully crushed, and there will be large particles, affecting the subsequent process; if the crushing time is too long, it will not only increase energy consumption and equipment wear, but also may damage the fiber structure. Usually, the crushing time is about 5 - 15 minutes. For some raw materials that are difficult to crush, it can be appropriately extended to 20 minutes, but the crushing effect needs to be closely observed.

[0073] Feeding Speed The feeding speed should match the processing capacity of the crushing equipment. If the feeding speed is too fast, the equipment load will be too large, which may cause equipment blockage or motor overload; if the feeding speed is too slow, the production efficiency will be reduced. Generally, according to the rated processing capacity of the equipment, it is more appropriate to control the feeding speed at about 70% - 80% of the maximum processing capacity of the equipment.

[0074] Cleaning Process Parameters:

[0075] Selection and Concentration of Cleaning Liquid Cleaning Liquid Type: Select appropriate cleaning liquid according to the type and nature of the stains on the surface of the raw materials. For oil stains, an alkaline cleaning liquid containing surfactants can be selected; for dust and water-soluble stains, clean water or a weak acidic cleaning liquid may be sufficient.

[0076] Concentration: If the concentration of the cleaning liquid is too high, it may damage the fibers and affect the material properties; if the concentration is too low, the stains cannot be effectively removed. Taking common alkaline cleaning liquid as an example, the concentration of sodium hydroxide is generally controlled at about 3% - 8%, and the concentration of surfactants is about 5% - 10%.

[0077] Cleaning Temperature Appropriately increasing the cleaning temperature can accelerate the dissolution and removal speed of stains, but too high a temperature will cause the fibers to expand excessively and may even lead to the destruction of the fiber structure. Generally, the cleaning temperature is controlled between 40 - 60 °C. For some fibers with better heat resistance, the temperature can be appropriately increased to 70 °C, but caution is required.

[0078] Washing time If the washing time is too short, the stains cannot be completely removed; if the washing time is too long, the fibers may be over-soaked, resulting in a decrease in strength. Generally, the washing time is about 15 - 30 minutes. For raw materials with heavier stains, it can be appropriately extended to 45 minutes, but pay attention to observing the state of the fibers.

[0079] Stirring intensity Stirring can make the cleaning liquid fully contact with the raw materials, improving the cleaning effect. However, too high a stirring intensity may damage the fibers. Generally, the stirring intensity is controlled by adjusting the rotation speed and shape of the stirring paddle to form an appropriate level of turbulence in the cleaning liquid to ensure uniform cleaning. For relatively fragile fibers, the rotation speed of the stirring paddle can be controlled at 100 - 200 revolutions per minute; for fibers with higher strength, the speed can be appropriately increased to 300 revolutions per minute.
