前言双十八烷基二甲基氯化铵(DOAC)已广泛用作织物柔软剂的最重要组分之一,已知DOAC在较高浓度可赋予织物柔软性和抗静电性,但是,由于它的疏水性,过量使用会降低棉织物的吸收能力。尽管某些研究会涉及DOAC水溶液的性能,但还没有说明织物柔软机理,而且,对不降低织物吸收性的织物柔软剂的研究还不充分。为了弄清织物柔软和吸收机理,该研究中使用DOAC和它的各种相似物,研究了铵盐对纤维的吸附状态,用铵盐处理棉纱和纤维的机械性能和吸附在固体
Preface Dioctadecyldimethylammonium chloride (DOAC) has been widely used as one of the most important components of fabric softeners and it is known that DOAC confers fabric softness and antistatic properties at higher concentrations, however, due to Its hydrophobicity, excessive use will reduce the absorption capacity of cotton fabric. Although some studies have dealt with the performance of DOAC aqueous solutions, the mechanism of fabric softening has not been elucidated yet, and research on fabric softeners that do not reduce the absorbency of the fabric is not sufficient. In order to clarify the fabric softening and absorption mechanism, DOAC and its various analogues were used in this study to investigate the adsorption of ammonium salts to fibers, the mechanical properties of cotton yarns and fibers treated with ammonium salts, and adsorption on solids
