Polybutylene succinate (PBS) fiber is a kind of synthetic fibers with excellent properties and biodegradability,which has been produced on a large scale in China.To investigate the application properties of PBS fibers,the structure and properties were systematically studied in this paper.The microstructures and thermal properties of PBS fibers were analyzed by Fourier transform infrared (FTIR) spectroscopy,X-ray diffraction (XRD),scanning electron microscopy (SEM),thermo gravimetric (TG) and differential scanning calorimetry (DSC).The mechanical properties,chemical stability and dyeing properties of PBS fibers were also studied.The results show that PBS fibers are a-crystalline with a crystallinity of 58.56％.PBS fibers have an excellent thermal stability and the initial temperature of thermal degradation is 370 ℃.The tensile strength,the elongation at break,the elastic recovery rate at a fixed elongation (5％) and the moisture regain rate of PBS fibers are 29.57 cN/tex,90.94％,44.55％ and 5.04％,respectively.The chemical stability is as follows: alkali resistance ＜ acid resistance ＜ oxidation resistance.PBS fibers have an excellent dye uptake by carrier dyeing of disperse dyes.
