通过对几种涂覆纳米纤维的机织和非织造布的详细表征，评价了纳米纤维作为织物涂层材料的潜力。本研究中使用的碳纳米纤维是从竹子和阔叶木漂白的硫酸盐纸浆中提取出来的，并通过水相反碰撞方法制备。将CNF悬浮液涂覆在不同的棉纤维或铜纤维制成的机织和非织造布上。对CNF涂层基板的物理性能和印刷质量进行了全面的表征。由于CNF涂层的存在，提高了材料的透气性。阔叶木CNF涂层比竹材CNF涂层表现出更高的抗透气性，这可能是由于较短的阔叶木CNF形成了更均匀和更精细的网络的结果。机织和非织造布经过CNF涂层后，其保温性能也得到了改善。碳纳米纤维能够覆盖和填充衬底材料中较大的孔隙，但不能覆盖和填充微孔。包裹在微孔中的空气层的适当部分确保了保温。在纺织品喷墨打印的情况下，墨水颜料保留在CNF层中，从而提高了颜色密度。
The potential of cellulose nanofibers (CNFs) as coating materials on fabrics was assessed by detailed characterization of several CNF-coated woven and nonwoven fabrics. The CNFs used in this study were derived from bamboo and hardwood bleached kraft pulps and prepared via an aqueous counter collision method. The CNF suspensions were coated onto different woven and nonwoven fabrics made from cotton or cuprammonium rayon. The physical properties and the printing quality of the CNF-coated substrates were thoroughly characterized. The resistance to air permeability increased because of the CNF coating. Hardwood-derived CNF coatings showed higher resistance to air permeability than those derived from bamboo, which could be the consequence of more-uniform and finer networks formed by the shorter hardwood-derived CNFs. The heat retention properties were also improved after CNF coating of the woven and nonwoven fabrics. The CNFs could cover and fill in larger pores in the substrate materials, but not the micropores. A suitable portion of the air layer entrapped in the micropores ensured heat retention. In the case of ink-jet printing on textiles, the ink pigments were retained within the CNF layer improving the color density.
