Study On Tanning Processing Technology Of Rana Chensinesis Skin And Product Design

This subject is based on the study of rana chensinensis skin tanning technology. Further more, we make product design with its antibacterial performance and other special appearance. The purpose of this subject is to make rana chensinensis skin tanned to solve its abandoned situation, so that we make more efficient use of the resource.Rana chensinensis originates from Dongbei Mountain such as Changbai Mountain. It is the endemic species in China, and it is species with food and medicine. There are nearly 300 million every year, but a lot keep disused. People are mainly concentrated on the study of rana chensinensis in recent 20 years or so. But mainly for collagen proteins, and research breakthough point focuses on medical science, health care and other fields. Northeast it has antibacterial performance significantly, but dose not have good development.Rana chensinensis skin tanning technology was studied with reference to the character in the process of similar skin tanning process, snake skin tanning process, as well as the bullfrog leather tanning process. Rana chensinensis skin, however, because of its character difference, this topic research method mainly adopts four factors of three levels and nine parallel experiments, and discusses the research selected tanning process important link of parallel design of experiment, respectively derived orthogonal experiment, tanning orthogonal experiment, the complex toughening orthogonal experiment and orthogonal test, the fatliquoring retanning orthogonal experiment. And through the senses a comprehensive evaluation of the performance test, wear-resisting performance test verification, finally be suitable for tanning process parameters of the rana chensinensis skin, and through the performance test. The surface collagen of the rana chensinensis skin can be hydrolyzed during the proteases action. Concentration and hydrolysis time by controlling the protease, can effectively control the rana chensinensis skin surface degree of hydrolysis of collagen, so as to get different leather of transparency. Transparent rana chensinensis skin prepares new materials for design.With the continuous improvement of people’s living standard, more and more people take travel to enjoy their holiday. According to the latest figures released by the “twelfth five-year” period, the growth of tourism and its related industry in China in the proportion of GDP reached 4.33%. Changbai Mountain as a 5 a-class tourist attractions, the economic benefits of tourism for local cannot be underestimated every year, and the income brought by tourism handicraft is considerable. Rana chensinensis as a unique species with local cultural characteristics in the northeast Changbai Mountain. Processed rana chensinensis skin has products processing performance, and its unique texture will bring a new bright spot for design. At the same time, rana chensinensis skin has antibacterial performance, so the key chain, plate shell, jewelry box, glasses box, mouse pads, bracelets and so on made of rana chensinensis skins on the premise of beautiful can have certain antibacterial function. We can also make full use of antibacterial properties of the rana chensinensis skin, and joining together to combine with other material for new materials to design, such as mentioned in the subject has antibacterial activity of the design of the insole. The fourth chapter of this article rana chensinensis skin product design is the sublimation of this topic, also is the research purpose of this subject. Rana chensinensis skin tourist crafts design for Changbai Mountain tourism industry will bring the economic income, and also will satisfy the consumer demand. The product development of rana chensinensis skin has good market prospects.
