| Abstract: | In order to study the spinnability and fiber degradation of biodegradable poly(butylene adipate-co-terephthalate)(PBAT),biodegradable PBAT fiber was prepared using a two-step method involving melt spinning and drafting.The effects of spinning temperature and drafting ratio on the crystallinity,moisture regain and mechanical properties of PBAT fiber were studied,and the degradation properties of PBAT fiber in different environments were compared and analyzed.The results show that the optimum spinning temperature of PBAT was 260℃,and with the increase of drafting ratio,the breaking strength,crystallinity and orientation of PBAT fiber increased rapidly,while the elongation at break decreased.It was found that the abiotic cold and dry environments had the least influence on the properties of PBAT fibers,where the fiber strength decreased by only 3.6%after one month storage under such a circumstance.Under biological conditions,on the other hand,the influence of soil was more obvious compared to enzymatic hydrolysis and hydrolysis,where the crystallinity of PBAT fiber decreased from 34.45%to 19.36%. |
