聚丙烯酸类浆料的纳米改性

Research on polyacrylic acid size modified by nanomaterial

利用分散的纳米TiO2溶液和多种丙烯酸类单体合成纳米改性聚丙烯酸类浆料——SX-5/TiO2。分别用SX-5/TiO2、SX-5以及PVA浆料和淀粉组成一定规格的混合浆进行单纱及片纱上浆实验,从而进行浆纱性能对比。实验结果显示:用分散的纳米TiO2溶液和多种丙烯酸类单体合成纳米改性聚丙烯酸类浆料是可行的;改性后的聚丙烯酸类浆料在贴伏浆纱毛羽,提高与纱线的黏附力和改善浆纱吸湿性等方面均比PVA浆料和未改性聚丙烯酸类浆料有所改善,可以替代PVA浆料。

A nanometer polyacrylic acid system size -- SX-5/TiO2 was synthesized from dispersed TiO2 solution and polyacrylic acid monomers. Sizing experiments of single yarn and sheet yarns were performed with SX-5/TiO2 ,SX-5, PVA and a mixture of starch. The results were compared and showed that SX-5/TiO2 exhibited less hairiness, better bonding strength and moisture absorbance when compared with PVA and conventional polyacrylic acid system size and it could be used for substitution for PVA.
