    Common shoe materials problems and treatment methods in shoe making process

    更新日期: 2019/9/27 9:24:22

    1. How can I reduce the discoloration of the bottom The dermis will discolor in wet and hot environments, which is currently not a problem. The method that people who are prone to sweat can choose: wear dark socks; choose PU shoes; or wear them every other day. 2. the shoes at the bottom of the leather will slip when worn, how to prevent The leather sole shoes are characterized by good air permeability, good comfort and good texture. This is one of the important features of high-end shoes; but the leather is not wearable and afraid of water. If you want to improve its wear resistance, you can put a rubber sole on the sole of the shoe before you wear it. It will be better, which not only prevents slipping, but also increases the wearing life of the shoe. Only in this way, the meaning of the leather bottom is lost. 3. Why are there many light-colored shoes that are black heels The design concept of the shoe determines that the heel is dark, and this design philosophy is sometimes followed by fashion trends. This season is the time when this design concept is popular, so you will find that many brands of shoes have this style. 4. Why are there small pinholes at the bottom of the cool leather shoes Because the leather shoes are cut by the pinhole point positioning method during the manufacturing process, there are small holes. This hole does not affect the quality, you can wear it with confidence. 5. Why do light-colored shoes sometimes have small black spots on the surface Since natural leather needs to be dyed, it can make various colors that we like. In the dyeing process, the dark color will cover the original stain. Light color should not be covered, this is all natural leather, black spots are stains on the leather. 6. Some of the colors of the molding base are also rubbed off with the eraser. What is the matter Because it is attached to the bottom of the molding, the color is attached to it, instead of being colored on the sole after molding, it will not discolor under normal conditions. 7. There are air holes on the bottom of the molding. The customer suspects that it is a quality problem. How should I explain it In the production process, due to the relationship of the mold, there will be a small hole like a bubble on the surface of the forming bottom, which is not a problem in the wearing process. 8. Is it not good to stick the sandals to the bottom The bottom of the sandals is made according to the production method prescribed by the state. The bottom of the sand is wrapped on the midsole, and then pressed by the special glue of high temperature + shoes, so you can wear it with confidence. 9. Will the film of the shoe crack The film used on the shoe is a specially-tested special shoe material that will not crack under normal wear and can be worn with confidence. The quality of our shoes is very good. If there is a problem, we will deal with it according to the “three guarantees” of the city. You can wear it with confidence. 10. What should I do if the shoes with film decoration wear dirty and yellow If not, what should I do Shoes with film decoration are more fashionable, and shoes with leather material are more distinctive and individual. However, it will indeed turn yellow when worn for a long time. So far, there is still no good solution for this problem country. Therefore, it emphasizes the selling point of fashion and personality. At the same time, it is recommended that guests pay more attention when wearing them, and pay attention to maintenance when not wearing them. 11. the molding base is not resistant to wear What to do after grinding off The bottom of the molding is non-slip and wearable and very comfortable to wear. This sole has good quality. According to the different wearing habits of the individual, the degree of wear of the heel is not the same. If there is any problem, you can take the shoes to the shoe repair shop and they will help you with it. 12. the difference between the leather bottom and PU hot bottom Leather bottom: good breathability, comfortable to wear, but easy to discolor in wet and hot conditions. PU bottom: breathability is slightly worse than leather, but it is not easy to discolor is its biggest advantage; our company uses imported breathable PU, performance and material are superior. 13. What kind of shoes are more suitable for people with more sweat The inner part of the shoe is generally made of genuine leather or imported breathable PU. Both of them are characterized by strong breathability and can be selected according to personal preference and characteristics. If the person with more sweat is wearing leather shoes, it is easy to fade and contaminate the socks. Such customers try to recommend that he choose the shoes with imported PU material. 14. The leather of the new shoes is very hard. Will it wear your feet when worn Mainly because the reason why no one has ever passed, the material of the new shoes is generally hard. Since our shoes are made of genuine leather, there are pores on the top, and the leather will become soft and heel as long as it touches the temperature for a while.

    Shoe Industry Industry 4.0

    更新日期: 2019/9/27 9:23:16

    The term Industry 4.0 has been heard recently, and many of its peers are listening to it. The production process of shoes is from simple handicraft workshops to mass production in later factories. The process is nothing more than buying materials, processing, molding, and shipping. What is the so-called production upgrade Let’s take a closer look. . In general, Industry 4.0 is a slogan proposed by Germany to improve the intelligence level of manufacturing, to build smart factories with adaptability, resource efficiency and human factors engineering, to integrate customers in business processes and value processes. business partner. The technical basis is the network entity system and the Internet of Things. The operation is to use the IOT information system to digitize and intelligentize the supply, manufacturing and sales information in production, and finally achieve fast, effective and personalized product supply. The "Industry 4.0" project in the footwear industry is divided into three main themes: The first is the "smart factory", which focuses on the research of intelligent production systems and processes, as well as the realization of networked distributed production facilities; the rational allocation of various departments to improve efficiency. To put it simply, it is a reasonable planning and layout of production processes and personnel positions to reduce repeated operations and improve utilization. The second is "intelligent production", which mainly involves the production logistics management of the entire enterprise, human-computer interaction and the application of 3D technology in industrial production processes. The program seeks to make SMEs a user and beneficiary of a new generation of intelligent production technology, and also a creator and supplier of advanced industrial production technology; the purchase of smart devices can promote the intelligentization of manufacturing processes and promote the construction of smart factories. The simulation optimization of the manufacturing process, digital control, real-time monitoring of state information and adaptive control, in order to achieve intelligent control of the entire process. In terms of footwear manufacturing, personalized customization, direct midsole, direct molds, and smart insoles make the application of this industry more and more radiating. 3D printing system + EMP cloud platform system provides all the data information of production printing in the form of two-way interaction for the large-scale production of shoe mold industry, so that multiple devices can be monitored, managed, recorded and stored in real time, and the orders are batched and intelligently scheduled. Real-time monitoring of production processes, monitoring of material consumption, reducing time wastage, cost savings, efficiency, and big data analysis. Planning, printing, and data work closely together to ensure that operator managers can grasp changes in the production site in the shortest possible time, make accurate judgments, and develop quick response measures. The mechanization of shoe production is to change the labor intensity and continuous manual process to mechanization. For example, CNC machine arm, high efficiency climbing, back machine, gluing machine and other manual labor effectively improve efficiency by more than 20 times. The third is "smart logistics", which mainly integrates logistics resources through the Internet, Internet of Things, and logistics network, and gives full play to the efficiency of existing logistics resource suppliers. On the demand side, it can quickly obtain service matching and obtain logistics support. Specifically, it is to use data technology to help merchants do store delivery, and to achieve online orders, offline delivery. The order is placed in the customer system, and the order is synchronously pushed into the factory system. The factory system automatically schedules the time and informs the departments. Each department operates the feedback display process until the final product is delivered to the customer's designated position, and the whole process can be traced back. In addition, through the combination of artificial intelligence technology and robot technology, a "system similar to no one" is created. The entire process of automated logistics, packaging links to achieve automation, improve the operational efficiency of warehousing, from product offline to loading and shipping, without manual intervention. Logistics robots will appear in large numbers. Whether it is Ali, Jingdong, or SF Express, all major express companies are investing in hardware development and application of intelligent logistics. As labor costs continue to increase, robot costs and labor costs will get closer. It is only a matter of time before simple repetitive labor is replaced by robots. From the industrial age of the first steam engine, human beings constantly explored innovations. Energy-saving emission reduction, efficiency improvement, big data drive the entire supply chain recombination, whether it is upstream raw materials, manufacturing end, or downstream distribution end, will be recombined, from linear, tree-like supply chain to mesh supply chain .

    Sole classification and characteristics

    更新日期: 2019/9/27 9:21:22

    Leather sole: The leather sole is a sole that can breathe automatically and breathe the foot. It has good air permeability and no loose feet. It can automatically release the absorbed sweat to keep the feet dry. The leather sole is mainly made of cowhide and the price is higher. The utility model has the advantages of easy setting, invariable type, fit, and good elasticity, can reduce impact without fatigue, ventilate, absorb moisture, etc., and is easy to process, and the shape is easy to display aesthetics. Hard texture is not easy to be pierced, but it is easy to warp or rot after being soaked in water and oil. Its main features: 1 has good thermal insulation to ensure the proper temperature of the foot in the shoe 2 Light weight, the weight per square centimeter is between 0.95 and 1.05 grams, just the same as the density of water. It is waterproof and releases moisture when the shoes are no longer wet, ensuring that the shoes are in a comfortable state. 3 Unique three-dimensional fiber structure, the sole does not break when it is bent at 180 degrees. It can quickly adapt to the shape of the foot, can effectively support the impact of the ground, and protect the foot more effectively than the sole of other materials of the same thickness. Rubber sole (RB): RB is an abbreviation for English rubber (rubber); hot compression molding, divided into natural rubber and recycled rubber. It is heavy and oil-resistant. When molding the bottom, it must be ground on the bonding surface. It is easy to shorten when heated, and the color is inconsistent. Advantages: good wear resistance, non-slip, elastic, not easy to break, good softness, good ductility, stable shrinkage, good hardness, good flexibility and waterproof. Disadvantages: heavier, easy to spit (it is a quality problem), not easy to corrode (environmental problems); not hard, easy to be punctured; breathable, hygroscopic, not afraid of oil soaking, not suitable for contact with oil at gas stations Place to wear. ※ Rubber foaming The weight is lighter than the rubber bottom, and it has a rubbery taste. When pressed with a finger, the surface rebound is more obvious than the general sole, and the wear resistance is poor. ※ High pressure polyethylene rubber sole The sole is made of high-pressure polyethylene and rubber flavor. It is used together with rubber and plastic. Raw rubber bottom: heavy, expensive, oil resistant, not heat resistant. Easy to change color. Polyurethane bottom (PU): Polyurethane is the abbreviation of polyurethane. The English name is polyurethane. It is a kind of polymer material. It is made of A/B/C polyester foam, which is divided into oil and water. It is an emerging organic polymer material, which is known as the “fifth largest plastic” and is used in the manufacture of high-grade leather shoes, sports shoes and travel shoes. Advantages: low density, soft texture, good elasticity, comfortable and light wearing; good oxidation resistance, excellent wear resistance, flexural resistance, high hardness; excellent shock absorption, anti-slip performance; better temperature resistance; Good chemical resistance; easy to corrode for environmental protection, not easy to wrinkle. Disadvantages: strong water absorption, easy yellowing, easy to break, poor elongation, water resistance, perishable bottom, poor gas permeability. EVA bottom: Ethylene Vinyl Acetate - vinyl acetate copolymer, polymer material. Commonly used for jogging, slow walking, casual shoes, foot training shoes midsole. Light weight, easy to process, not wearable, not resistant to oil. Advantages: light weight, good elasticity, good flexibility, not wrinkle, excellent coloration, suitable for all kinds of climate. Disadvantages: easy to absorb water, not easy to corrode, environmentally friendly, easy to dirty. MD bottom: The collective name of MODEL or PHYLON is a secondary high pressure molded product of EVA. The MD sole must contain EVA inside, and the MD bottom is also called PHYLON bottom. For example, MD=EVA+RB or EVA+RB+TPR and some shoes are RB+PU. Advantages: light, flexible, fine appearance, softness; easy to clean; hardness, density, tension, tear, elongation. Disadvantages: It is not easy to corrode and is not environmentally friendly. It is easy to wrinkle and shrink when it is high temperature. It has poor durability. When it is used for a long time, its shock absorption will be reduced and the gas permeability will be poor. TPR bottom: TPR is originally a general term, including TPV, SEBS, SBS, TPO, TPU, EVA and other products. The TPR sole is mainly referred to as the SBS modified shoe material (a type of application belonging to the TPR material). TPR shoe material is a new type of polymer shoe material mainly produced by thermoplastic SBS. It has the properties of rubber and can be processed and recycled according to thermoplastic. It can be molded and extruded by ordinary plastic molding machine. And blow molding to make rubber products. After the TPR pellets are hot melted, they are injection molded, and the molecules move in an emissive manner during molding. Advantages: easy to shape, cheap; light, comfortable, high elasticity, easy to stain, good ventilation, high strength, especially excellent low temperature resistance, high friction coefficient, strong grip. Disadvantages: heavy material, poor wear (no wear resistance), poor softness, poor bendability (not resistant to folding), poor shock absorption, poor gas permeability. TPU bottom: The full name of thermoplastic polyurethane elastomer (Thermoplastic Polyurethane), which is a linear polymer material formed by the reaction of diisocyanate and macromolecular polyol and chain extender, is a new environmentally friendly material. Advantages: Excellent mechanical strength, wear resistance, oil resistance and flex resistance, especially wear resistance is the most outstanding, good appearance, generous and high-grade. Disadvantages: heat resistance, hot water resistance, compression resistance is poor, the appearance is easy to turn yellow, easy to stick mold during processing, harder, heavier, poor gas permeability. PVC bottom (imitation leather): Polyvinyl chloride, the color is yellowish translucent and shiny. Whitening occurs at the bend. Advantages: Most are cheaper, oil resistant, wear resistant and have good insulation properties. Disadvantages: poor anti-skid performance, poor texture, not cold resistant, not resistant to folding, poor gas permeability. TR bottom: TR sole material is a new product improved on the basis of TPR. It is a synthetic material of TPE and rubber. The product has excellent performance of various indexes. It is formed by hot injection molding, and the molecules move in a rolling ball shape during molding. It has the characteristics of many appearances, good hand feeling, bright color, high smoothness and high technical content, and can be 100% recycled. It is an environmentally friendly sole material. Imitation leather bottom: It is a typical rubber and plastic material with high elasticity. The main component is rubber-based. It is made of 10% to 30% high styrene and is made of leather bottom leather. Appearance is similar to natural bottom leather, with grain pattern, which makes the products light and clear, the lines are clear; the lightness and comfort when wearing, and there is no sound, non-slip, wear-resistant, such a sole has both good elasticity and comparison. High hardness and rigidity, its performance is very similar to natural leather. Although it does not have the breathability and moisture absorption properties of natural leather, it also has the advantage of not being afraid of water. BPU It is a modified new type of polyurethane (PU), which has the advantages of environmental protection, low density (ultra-light weight), thick surface crust (smooth surface), good toughness, not easy to break, and good weather resistance. It can replace EVA outsole, EVA waterproof platform, air-blown PVC bottom platform, wooden shoes, PVC foaming bottom table, etc. This modified polyurethane imitation wood material is very light, with beautiful wood grain, temperature resistance, and adjustable degradation period. It is a new environmentally friendly material. Beef tendon (Tianjin) bottom: Thermoplastic elastomer bottom, a light yellow translucent sole, named for its color and character like beef tendons. "Bottom of the tendon" is described as strong as the tendon, but the bottom of the tendon is artificially made, also called the thermoplastic elastic rubber sole. (The first is from the rubber tendon. At the time, it was mainly made of sandals and the color and other materials were linked together to be called beef tendon. It can be said that the beef tends to refer to natural rubber first, and later evolved into a color card.) The bottom of the tendon can be made of rubber or plastic, and it is most convenient to make it with thermoplastic rubber (TPR). The sole has a beautiful appearance, and has good elasticity and wear resistance, is comfortable to wear, and has no sound when walking. It is a good sole material for sneakers and daily life shoes. Rubber tendon: There will be a layer of misty secretion on the surface of the whitening for a long time; use a blade to cut a little black with a fire to make a white solid residue a little white, it is difficult to appear dripping when burning, and there is a little black smoke in the rubber smell. (Some technical development of some rubber tendon secretions may not appear.) TPR beef tendon: use a knife to cut a little with fire, when burning, there is a black smoke mixed with a little gray-green, a kind of dripping phenomenon, a gel smell, burning time is a little faster than rubber tendon, leaving a little black coke solid. Beautiful bottom: Mei Nai Di (also known as the board, Ledo rod and rubber imitation leather bottom, etc.), in fact, is also a rubber sole, but the processing method is different. It is cheaper than the United States. The main ingredient of the company is rubber, which is fine, wear-resistant and tortuous. It is infinitely extended. It is generally 1 meter wide and cuts into 2 meters from the rolling machine. It must be punched with a punching knife and then ground and colored. The thickness is usually between 3-5mm, depending on the demand. Raw rubber bottom: Raw rubber is a general term for unplasticized and rubberized rubber. It is the most basic raw material for the manufacture of rubber compounds, including natural rubber and synthetic rubber. The raw rubber bottom that we call everyday is wear-resistant. The raw rubber bottom here is actually the bottom of the cooked rubber. It is the raw rubber after the treatment, but the appearance is like raw rubber. It is a mistake we have made. The plasticizing effect of raw rubber is poor, the hardness, density is low, easy to wear and break; the characteristics of cooked rubber are just the opposite, and the wear resistance and toughness are better. Cooked rubber is widely used, such as car tires; raw rubber is only used to make low-end household items, such as slippers. PC bottom: Polycarbonate (PC) resin is a thermoplastic engineering plastic with excellent performance. It has outstanding impact resistance, good creep resistance and dimensional stability, low heat resistance, low water absorption, non-toxicity and excellent dielectric properties. It is the top five. The only product with good transparency in engineering plastics is also the fastest growing general engineering plastic in recent years. The PC bottom has the characteristics of good weather resistance, beautiful appearance, impact resistance, high light transmittance and strong plasticity. ABS bottom: Acrylonitrile Butadiene Styrene, acrylonitrile-butadiene-styrene copolymer. ABS engineering plastics are generally opaque, the appearance is light ivory, non-toxic, tasteless, with tough, hard, rigid characteristics, slow burning, yellow flame, black smoke, softened, burnt, and special after burning The smell of cinnamon, but no melting dripping phenomenon. It has excellent comprehensive performance, excellent impact strength, good dimensional stability, electrical properties, wear resistance, chemical resistance, dyeability, molding processing and mechanical processing. Disadvantages: low heat distortion temperature, flammable, and poor weather resistance. PE bottom: PE plastic (polyethylene), English name: Polyethylene. Excellent corrosion resistance, electrical insulation (especially high frequency insulation), high rigidity, hardness and strength, low water absorption, good electrical properties and radiation resistance. PE bottom has good flexibility, elongation, impact strength and permeability; it has good fatigue resistance, wear resistance and corrosion resistance. PP bottom: PP plastic (polypropylene), English name: Polypropylene. It is a high-density, side-chain-free, highly crystalline linear polymer with excellent overall properties. It is white translucent when uncolored, waxy; lighter than polyethylene. Transparency is also better than polyethylene and harder than polyethylene. PP sole has low density, good strength, rigidity, hardness and heat resistance; it has good electrical properties and high-frequency insulation, and is not affected by humidity and corrosion. However, it becomes brittle at low temperature, is not wear-resistant, and is easy to age, and is easily decomposed under certain conditions. SBR bottom: Styrene butadiene rubber is a polymer elastomer material synthesized by copolymerization of butadiene and styrene as main monomers. The quality is uniform and pure, and impurities are mixed less. Soluble in benzene, toluene, gasoline, chloroform and other organic solvents. The unsaturated double bond in the styrene-butadiene rubber molecule and the vulcanizing agent form a crosslinked network structure by substitution or addition reaction, and the styrene-butadiene vulcanizate reinforced by the reinforcing agent has high physical and mechanical properties. Styrene-butadiene rubber has a slow vulcanization rate, but has good vulcanization flatness, is not easy to be vulcanized, and has excellent properties such as aging resistance, heat resistance and wear resistance. Cork, wooden bottom other kind: Mixed materials such as SBR, TPR, ABS, and PVC / EVA / PU return materials; hemp knitting, wool spinning, etc.
