For westerners, sticking a mask on the face of East Asians can easily remind them of the outbreak of SARS in 2003. As a medical tool, the mask is used to prevent viruses, bacteria, harmful gases and dust from spreading through breathing and mouth.
In January 2017, a survey of 2004 people conducted by the social survey center of China Youth Daily through the questionnaire network showed that 55.5% of the respondents would definitely wear masks in case of haze or bad indoor air, and 31.8% would depend on the situation. On March 8-11, 2018, the white paper on indoor formaldehyde pollution in China, initiated and directed by China Quality Inspection Association, was grandly released, which comprehensively and deeply analyzed the current situation of indoor formaldehyde pollution after home decoration in China for the first time from a professional perspective, calling on the public to pay attention to the health hazards caused by indoor formaldehyde pollution. As a result, the mask subculture originated in Japan gradually spread to China and formed a trend. In addition to hiding the face without makeup, keeping warm, making the face look smaller, and preventing the throat from getting too dry during sleep, wearing masks indoors stems from the current situation that the indoor air environment is getting worse and worse. Authoritative data show that the number of deaths caused by indoor pollution in China reaches 111000 every year. Among many indoor chemical pollutants, formaldehyde makes people turn pale. Exceeding the standard of formaldehyde will send out pungent smell and cause fatal diseases such as nasopharyngeal carcinoma, paranasal sinus cancer and leukemia. In the artificial cortex widely used in household products in the past few decades, there are many hidden dangers of formaldehyde exceeding the standard due to the use of a large number of chemicals in its production process. In the rapidly changing home industry, the application of leather in home is undergoing a change. Environmentally friendly leather is gradually replacing traditional synthetic leather and artificial leather.
For ordinary consumers, a satisfactory leather furniture must first have excellent raw materials and detailed technology, and most of us still stay in the concepts of "genuine leather", "PVC" and "Pu". However, the traditional three leathers are different. 1. Leather: leather is a natural leather material made from the raw leather of cattle, sheep, pigs, horses and other animals after tanning. It has the advantages of flexibility and ventilation. Due to the scarcity of leather, leather goods are usually expensive and need careful maintenance. They are not suitable for high mechanical tensile equipment and furniture. 2. PVC leather: PVC leather and PU leather are often collectively referred to as artificial leather. In fact, their manufacturing processes are different. The appearance and feel of PVC leather are similar to that of leather, but it is easier to wear and aging than leather. It is a kind of imitation leather product made of a large number of chemical raw materials and plastics. 3. PU leather: PU leather is processed with PU resin and non-woven fabric as raw materials, so it is also called PU synthetic leather. PU leather is superior to PVC leather in terms of manufacturing process, ductility and service life. Since the 1960s, PU leather has been widely used in the decoration of clothing, shoe bags and automobile furniture. In view of the advantages and disadvantages of the three kinds of leather, the market urgently needs a leather more suitable for the environmental protection needs of modern home decoration - EPU leather not only includes the advantages of the above three, but also is more environmentally friendly and easy to maintain.
The full name of EPU leather (solvent-free) ecological polyurethane synthetic leather is developed with international leading technical concepts and process equipment. There is no organic solvent and water in the manufacturing process, which reduces the heat energy to be absorbed by the volatilization of solvent and water. Compared with the traditional synthetic leather process, it greatly reduces energy consumption and waste, and truly realizes low-carbon production and green energy saving. As synthetic leather, EPU leather has the following advantages over PU leather: 1. EPU leather feels soft and smooth, fine and close to the skin, more toughness and elasticity; 2. It is more wear-resistant, scratch resistant, not easy to peel, not easy to crack, and does not need special care; 3. The service life of a fine EPU leather can reach 20 years and the color durability is longer; 4. Affected by the temperature rise, PU leather is easy to emit pungent chemical smell, and irreversible deformation and wrinkling occur with the increase of heat. EPU leather is more heat-resistant and has better ductility; 5. EPU skin is more environmentally friendly in the production process, abandoning the use of solvents and chemical reagents, more green and environmental protection, and does not contain harmful substances such as heavy metals harmful to human body. With the improvement of the quality of life, people have higher and higher requirements for the comfort of household products, and the consumption habits and consumption psychology are slowly changing. The pursuit of higher quality of life makes massage chairs become the consumption concept of more and more families. EPU leather has become a better choice for massage chair leather because it breaks through the traditional delicacy and toughness. In the furniture, sofa and car seat industry, due to low flexibility requirements and high pricing, most high-end brands use leather. However, in the massage chair market, due to high toughness requirements for materials and low cost threshold, most brand massage chairs use traditional PU leather. Only a small number of brands use PU leather in order to reduce costs and even simplify processes, But environmental standards have been lowered. It is reported that before 2017, about 80% of enterprises in the massage chair Market used PU leather, 15% of enterprises used PVC leather and 5% of enterprises used other leather. In 2017, as the first year of EPU leather, KGC kajieshi, an innovative brand of smart home, and Amway Co., Ltd., a global leading brand of polyurethane synthetic leather, officially launched (solvent-free) ecological polyurethane synthetic leather and applied it to the production process of massage chair for the first time.
As the first massage chair brand to try new materials, KGC kajieshi's Xingyue intelligent massage chair and twilight intelligent massage chair both use EPU leather as the seat leather to meet the use needs of massage chairs while meeting environmental protection standards. According to the physical test, when the massage chair manipulator operates 360 °, the EPU leather can withstand up to thousands of stretching, which fully meets the needs of massage techniques and ensures the massage range, massage strength and massage depth; For massage chair with hot compress function, EPU leather can withstand heating of about 55 ° C for hundreds of hours. In addition, because the posture of the massage chair often changes during operation, the good resilience of the EPU ensures that it can return to the original state when the massage chair is reset. Nowadays, more and more young people pay attention to health preservation. A massage chair at home is of great help to improve the quality of life, regular work and rest time and improve the quality of sleep. Only an environmentally friendly and comfortable seat leather can enable consumers to have a safer and healthy rest and relaxation.
