摘要
为了减少纯棉高细号纱上浆浆料中PVA的用量,在上浆浆液的常规配方中添加不同种类以及不同比例的无机纳米粒子,相应降低PVA的含量,制成纳米改性浆料;测试浆液的黏度、黏附性和浆纱的渗透、被覆效果和浆膜完整率;通过Olmpus BX-51型高倍光学显微镜观察常规浆液和纳米浆液,分析无机纳米粒子对浆料改性的作用机制。结果表明:添加无机纳米粒子可以降低浆液的黏度,增加浆液的黏附性,改善浆纱的渗透和被覆效果,提高浆膜完整率;纳米改性浆液形成明显的网络状蜂巢结构,无机纳米粒子分布在接点处,增加了混合浆料聚合物中各相的混溶效应。
In order to reduce PVA proportion in sizing solution used for pure cotton finer yams, nanomodified size can be prepared by adding different kinds of inorganic nanoparticles according to different proportions into a size commonly used for finer cotton yams, reducing PVA content accordingly. The viscosity, adhesion, penetrating and covering effects as well as the completeness of the size film of the nanomodified size were tested. Optical microscope Olmpus BX-51 was used to examine the conventional and nanomodified sizes and the acting principle of modifying effect of nanoparticles was analyzed. The results indicated that addition of inorganic nanoparticles could reduce the viscosity of the size, enhance its adhesion, and improve the penetrating and covering effects and the completeness of the size film. A structure of net-like honeycomb was seen and the nanoparticle molecules were distributed at the juncture as observed on the fiber sized by nanomodified size, and it demonstrated that its mixing effect was improved.
