At present,the nylon fibers on the market are mainly nylon 6 and nylon 66,and their produc-tion is mainly based on the synthesis of non-renewable petroleum raw materials,and the cost is high.With the development of society,the production of traditional nylon fiber has increasingly serious load on the envi-ronment.Therefore,the development and application of bio-kinisaurus derived from renewable resources is of great significance to environmental protection and sustainable development.Bio-kinisaurus 510 was prepared by polymerization of maleic acid(biobased maleic acid)extracted from castor oil plant and pentenediamine(bio-based 1,5-pentenediamine)extracted from corn stalk.The color processing of nylon 510 fabric was studied,which laid a foundation for the application of nylon 510 material.
