| Abstract: | To address the problems of gelatin gelling at room temperature and poor toughness of size film when gelatin is used to sizing wool yarns,the modified gelatin protein(Gel-C4H4O3)for sizing at room temperature was prepared by acylation of gelatin with succinic anhydride(C4H4O3).The structure and glass transition temperature of Gel-C4H4O3 sizing agent were tested and characterized by infrared spectroscopy,X-ray diffraction,scanning electron microscope and differential scanning calorimeter.The relationship between the acylation degree and the size liquid and membrane properties of Gel-C4H4O3 was systematically studied.The results show that C4H4O3 can react with the amino groups on the gelatin molecular chain.Compared with the existing acrylic,acrylamide or acrylate monomers-grafted gelatin,Gel-C4H4O3 exhibited no gel at room temperature.When the acylation degree is 0.96,Gel-C4H4O3 size liquid showed excellent adhesion to wool yarn and the fracture strength and toughness of Gel-C4H4O3 size membrane are significantly increased.It provides an excellent sizing agent preparation method for wool yarn sizing at room temperature. |
