摘要(Abstract)：
探讨聚乙烯醇纤维半成品水中软化点(即ＲＰ值)与纤维本身的水中收缩曲线、结晶度大小以及一些条件如升温速率、丝束纤维所处横向方位之间的关系。提出工业生产中测定ＲＰ值应注意的一些事项。
The relationship between softening point in water of PVAc semi-finished product and its contraction curve in water, crystallinity and some conditions such as rate of raising temperature and position of the sample is discussed. Some points for attention are put forward on determining RP value.
