How to develop the warp sizing process with energy saving and emission reduction have been a problem for the textile sizing industry. In this work, a series of carboxymethyl cellulose nanofibers (CCNFs) with different degree of substitution (DS) were prepared from bleached eucalyptus kraft pulp, and their applications in warp size of textile were investigated in detail. AFM and TEM analyses confirmed that the prepared CCNFs were of nanoscale fibers. Zeta potential analysis showed that CCNFs aqueous dispersion had good stability. Response surface methodology was applied to optimize the high-count cotton warp sizing formula containing a small amount of CCNFs. It could be found that the optimized sizing formula still had much better sizing performance than that of the original sizing formula even if the sizing percentage and temperature were reduced. The results exhibited that CCNFs with DS of 0.38 had a potential industry application prospect as sizing auxiliary in pure cotton warp sizing, and the new developed sizing formula had the advantages of excellent sizing performance, environmental friendliness, energy saving and emission reduction.
如何开发具有节能减排功能的经纱上浆工艺一直是纺织上浆行业面临的一个问题。在这项工作中，以漂白桉木硫酸盐浆为原料制备了一系列不同取代度（DS）的羧甲基纤维素纳米纤维（CCNFs），并详细研究了它们在纺织经纱上浆中的应用。原子力显微镜（AFM）和透射电子显微镜（TEM）分析证实所制备的CCNFs为纳米级纤维。zeta电位分析表明CCNFs水分散体具有良好的稳定性。应用响应面法优化了含少量CCNFs的高支纯棉经纱上浆配方。结果发现，即使上浆率和温度降低，优化后的上浆配方的上浆性能仍比原上浆配方好得多。结果表明，取代度为0.38的CCNFs作为纯棉经纱上浆的上浆助剂具有潜在的工业应用前景，新开发的上浆配方具有上浆性能优异、环境友好、节能减排等优点。
