摘　　要：探讨PTT与PET混和纤维混纺比的新测定方法。根据PET与PTT纤维的熔点差异,采用湿法制样,在改进的YG252A型熔点仪上研究PTT纤维在PTT与PET混和纤维中的质量百分含量与其熔融后透光量变化量的关系。研究表明:两者之间的线性相关系数达0.971,且该检测方法的相对偏差小于7.0%,误差较小,工作曲线可靠。认为:所提出的新方法为PTT与PET、PBT与PET等特殊混纺织物的混纺比测定提供了一种思路。New test method for blending ratio of PTT and PET blended fiber was discussed. Based on the difference between melting point of PET and PTT, adopting wet sampling method, the relationship between weight percentage of PTT in PTT and PET blended fiber and their light penetration amount variation after melt- ing was studied on improved YG252A melting point device. The study shows that the linear correlation coefficient of the above two is up to 0. 971 ,the relative deviation of the test method is smaller than 7.0%. The error is smal- ler error and the working curve is reliable. It is considered that the new method provide a new way to test the blendinu ratio of PTT and PET,PBT and PET blended fabric.
