The elasticity recovering mechanism of PTT fibers was studied through the ordering transformation of molecular chainconformation in aggregation of fibers in the course of processing and using.
The fold in the chain is completed using only 3 or 4 monomer units with bonds in the gauche conformation.
链中的折叠仅使用3或4个具有 gauche 构象键的单体单元完成。
3
This three-dimensional conformation is held together by the interactions of the amino acids at different parts of the polypeptide chain with each other, and determines the activity of the protein.
