控制聚乙烯/聚丙烯双组分复合材料潜在卷曲性的研究根据聚丙烯纤维各组分的弹性收缩率和热收缩率的信息，制备了聚丙烯纤维。通过在100 ℃或更高温度下拉伸组分聚合物的流速比大于3的双组分纤维，并以3或更大的拉伸比拉伸，可以获得低潜在卷曲性。结果表明，根据温度效应来解释，该温度效应根据它们之间的界面形状而对两个部件中的每一个给予不同的收缩。
A study of controlling the latent crimpability in the bicomponent polyethylene/polypropylene fibers has been made according to the information on the elastic and thermal shrinkages for each component of the fiber.The low latent crimpability can be obtained by drawing at 100°C or higher and a drawing ratio of 3 or larger of the bicomponent fiber of which the flow rate ratio of the component polymers is larger than 3.The results are explained in terms of the temperature effect which gives the different shrinkage to each of the two components, depending on the shape of the interface between them.
