Gelatin prepared from bone of cow gives soft touch to human skin. However, drawing of gelatin film was very difficult. To prepare fibers with soft touch to human body, the blends of gelatin and poly (vinylalcohol)(PVA) were prepared by gelation/crystallization from solutions in dimethyl sulfoxide (Me_2SO) and water mixtures. The Me_2SO and H_2O composition was set to be 60/40. The solutions were prepared by heating the well-blended polymer/solvent mixture at 80℃ for 10 min. The hot homogenized solution was quenched to the desired temperature and dried at the same temperature. The macroscopic phase separation was observed at temperature higher than 50℃. The specimen could not be elongated. On the other hand, the solution was quenched to room temperature lower than spinodal temperature, the microscopic phase separation occurred. The resultant film after evaporating solvent could be elongated up to 5 times. X-ray diffraction from the mixed solutions detected by a curved PSPC system indicated that the crystallization of PVA occurs rapidly as the cooling temperature decreases but any information cannot be detected for gelatin. Anyway, it was confirmed that the draw ratio of PVA-gelatin blends depends on the quenching temperature. This mechanism shall be discussed later.

牛骨制成的明胶给人的皮肤带来柔软的触感。然而，明胶薄膜的绘制非常困难。为了制备对人体具有柔软触感的纤维，以二甲基亚砜(Me2SO)和水的混合溶液为原料，采用凝胶/结晶法制备了明胶/聚乙烯醇(PVA)共混物。Me_2SO和H_2O的组成为60/40。将完全混合的聚合物/溶剂混合物在80℃下加热10分钟，即可制备出溶液。将热均质溶液淬火至所需温度，并在相同温度下干燥。在高于50℃的温度下观察到宏观相分离。试件不能拉长。当溶液淬火至低于调幅点温度的室温时，发生微观相分离。溶剂挥发后得到的薄膜可伸长达5倍。由弯曲的PSPC系统检测到的混合溶液的X射线衍射表明，随着冷却温度的降低，PVA的结晶迅速发生，而明胶则没有检测到任何信息。总之，证实了PVA-明胶共混物的拉伸倍数取决于淬火温度。这一机制将在以后讨论。
