摘要: 以钠基蒙脱土、丙烯酸类单体和聚乙烯醇为原料,通过溶液原位聚合法和溶液插层法分别制备出不同蒙脱土含量的丙烯酸系共聚物/蒙脱土纳米复合浆料和聚乙烯醇/蒙脱土纳米复合浆料。用X射线衍射(XRD)法测定纳米复合材料中蒙脱土的层间距,并测定纳米复合浆料对纤维的黏附性和浆纱强力。试验结果表明,当蒙脱土含量较少时,形成了剥离型纳米复合材料,随着蒙脱土含量的增加,形成插层-剥离型和插层型纳米复合材料;丙烯酸系纳米浆料有利于提高对纯棉纤维的黏附性,并提高浆纱的断裂强力,而聚乙烯醇纳米浆料可提高对涤/棉的黏附性,对浆纱强力的影响不大。

Abstract: Acrylic copolymer /montmorillonite nano-size(Ⅰ) and poly(vinyl alcohol)/ montmorillonite nano-size(Ⅱ) each with different contents of montmorillonite were prepared respectively in presence of Na~+-MMT by in-situ intercalative polymerization of acrylic acid(AA),acrylamide(AM) and methyl acrylate(MA) in water solution,and by intercalation of poly(vinyl alcohol)(PVA) from solution, for sizing cotton and polyethylene terephthalate(PET) blended yarns.The interlayer space of montmorillonite in the nanocomposites was characterized by means of XRD,and the adhesion of the nano-sizes to the yarns and the strength of the sized yarns were tested.The results revealed that the degree of intercalation varies with amount of Na~+-MMT in the hybrid.The acrylic copolymer/Na~+-MMT nanocomposite size can improve the adhesion of the size to cotton,resulting in an increase of strength and elongation of the sized yarn.Whereas,the PVA/Na~+-MMT nanocomposite size can enhance the adhesion to the T/C blended yarn but have little influence on the strength and elongation.
