摘要

High-tension multiannnealing (HTMA)was applied to improve the tensile properties of poly(p-phenylene sulfide)fibers, which was furthermore applied to the fibers produced and improved with the zone-drawing nd zone-annealing treatments.The HTMA treatment was repeatedly applied to the fibers under the conditions of a 250deg C temperature and an aplied tension of between 201.0 and 188.0 MPa. As a result,at the 13th treatment the degree of crystallinity increased to 40%.On the other hand,the orientation factor of crystallites increased dramatically to 0.982 during the zonedrawing treatment, but increased only slightly during the subsequent treatments of zone annealing and HTMA. The finally obtained fiber had a tensil modulus of 10.4GPa and a tensile strength of 0.73 GPa.
