Diquaternary ammonium cellulosic fabrics with wrinkle resistant properties

摘要

Diethylaminoethyl (DEAE)-Cotton, prepared so that the tertiary amine nitrogens have unshared electrons and are thus in the Lewis-base form, is reacted with an alcoholic solution of an alpha-omega dihaloalkane to quaternize amino groups. The fabric produced by this process is crosslinked between tertiary amine nitrogen groups in cellulose and every alkylene group introduced is connected to two quaternary ammonium ions. The products of this process have strong base anion exchange properties and fabrics of high nitrogen content are imparted both wet and dry crease resistance.
