摘　　要：测定了聚酯复丝内各根纤维和一根纤维的线密度、强度和断裂伸长 ,并用 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 .结果表明 :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 .聚酯纤维的强度较好地符合Weibull分布 ,且也发现存在斜率变化现象 .The linear density, tenacity and its distribution, elongation and its distribution of a fiber in 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 considerable than it of INTER. Weibull distribution model fits well to tenacity of PET fibers.
