摘　　要：测定了聚酯复丝内各根纤维和一根纤维的线密度、强度以及断裂伸长 ,并利用Weibull分布模型分析了复丝内各根纤维和一根纤维的强度分布 .得出 :复丝内各根纤维间和一根纤维的断裂强度不匀基本相同 ,都小于断裂伸长不匀 .聚酯复丝中单纤维的强度较好地符合Weibull分布 ,同时存在斜率变化现象 .The linear density, tenacity and its distribution, elongation and its distribution of a fiber within a PET multifilament (IN) and fibers in it (INTER) are investigated and compared. Tenacity unevenness of IN and INTER is almost equivalent, however, elongation unevenness of IN is more considerable than that of INTER. Weibull distribution model fits well to tenacity of PET fibers.

关 键 词：聚酯复丝 聚酯纤维 断裂伸长 强度分布 断裂概率
