Abstract

The influence of the bentonite content (1, 3, 5 wt%) on the mechanical properties of lightweightcotton (C), polyester (P) and polyester-cotton (P/C 50/50) fabrics was investigated. Starch was used asa water-insoluble binder for coating fabrics. Bentonite nanoparticles were obtained by repeated hydration,decantation and evaporation of the water dispersion. The bentonite particle size was determinedby the XRD method using the Debye-Scherrer equation. The diffraction of the laser beam was used todetermine particles size distribution. The addition of bentonite nanoclay significantly improved tensilestrength (26-61% and 99–118% in the warp and weft direction, respectively) and tear strength (4‒13%and 5–24% in the wrap and weft direction, respectively) of coated fabrics. Their abrasion resistancehas also slightly increased. The biggest changes were noted for the cotton fabric, the smallest for thepolyester fabric, which may result from the low compatibility between starch and the polyester fabric.
纺织用膨润土纳米粘土改性研究
研究了膨润土含量(1,3,5 wt%)对轻质棉(C)、涤纶(P)和涤棉(P/C 50/50)织物力学性能的影响。将淀粉作为不溶于水的粘合剂用于涂料织物。通过反复水化、滗析和水分散蒸发得到膨润土纳米颗粒。采用Debye-Scherrer方程,用XRD法测定了膨润土的粒径。利用激光束的衍射来确定颗粒的大小分布。膨润土纳米粘土的添加显著提高了涂层织物的抗拉强度(经纬方向分别为26-61%和99-118%)和撕裂强度(纬向和包绕方向分别为4 - 13%和5-24%)。它们的耐磨性也略有提高。棉织物的变化最大,涤纶织物的变化最小,这可能是由于淀粉与涤纶织物之间的相容性较低。
