Wang Quanjie: Using Biomass Materials Is The Inevitable Trend Of Leather Making.

At the venue of the "2014 Tenth National Leather Chemicals Symposium", which is being held at the Jinhe Hotel Chengdu Conference Center, the director of the research and extension center of the national a href= "http:// www.sjfzxm.com/news/index_c.asp" > tannery technology < /a >, Wang Quan Jie, a professor at Yantai University, has just concluded the academic report on "sustainable development of leather industry and utilization of biomass waste". The audience applauded enthusiastically for the forty year old professor who was engaged in leather research and research and industrialization for the achievement of scientific research.

< p > review the development history of < a href= "http:// www.sjfzxm.com/news/index_c.asp" > leather industry < /a >, perhaps you will be surprised to find that the historical length of any industry can not match the leather industry.

The first garment of human beings is made from animal skin, and biomass material is the first material of a href= "http:// www.sjfzxm.com/news/index_c.asp" > Leather > /a > leather since ancient times.

Raw leather or fur making material is used as a drying and smoking fumigant for aldehyde tanning, or oil tanning, vegetable tanning, pickling tanning, flour tanning, or enzyme softening, protein filling, plant dyeing, flaxseed oil and cattle blood.

< p > What are the main sources of biomass tannery materials? Wang Quanjie's report mentioned that wastes from aquatic animals and plants, by-products of livestock and poultry, waste products, forest products and herbs can be the source of leather materials.

Wang Quanjie explained that fish skin leather has been in existence since ancient times. Unfortunately, waste disposal is more than 80%. Pretreatment with fish oil fatliquoring agent should be strengthened. Chitin and aquatic plants can also be used for tannery materials. Leather waste, including waste hair and scrap shavings, should be fully utilized, such as hydrolysis of waste hair and filling agent, animal fat and new tannery materials and materials. Roots, stems, skins, leaves and husks of trees can be used as sources of plant polyphenols extract.

< p > Wang Quanjie also enumerated many cases and experiments to prove that some biomass materials have achieved new breakthroughs in the leather industry.

The research team made use of waste wool crosslinking modification to prepare filling agent, which is better than regular keratin filler. The alkyl sulfonyl chloride plus leather hydrolysate can be used to make leather surfactants, and has been put into trial production. Yantai has tried leather made from tripe, louver and casing, made of decorative leather from chicken feet and ostrich feet, processed with trypsin from chicken litter and chicken pancreas, and the cost of raw materials is zero. Yantai University also extracted tannin from chestnut shell, producing about 20%, and has entered the pilot stage. In addition, the Yantai University also used hydrothermal method to extract Artemisia argyi to prepare microcapsules for leather mildew prevention and beriberi prevention. His Institute

< p > it is reported that China's chromite is scarce, and it is not enough for two years. Biomass material pollution is small, volume is large, renewable, leather products wear good, and most of the by-products and wastes of biomass materials can be utilized. Its superiority is self-evident.

Wang Quanjie believes that the development of biomass materials has become an inevitable trend of leather industry's sustainable development.
