Cotton cellulose was subjected to repeated swelling treatment with aqueous solutions of ethylenediamine (EDA). Although EDA is capable of effecting a lattice change from cellulose I to cellulose II during successive swelling treatments, resistance to lattice transformation is offered during the first treatment in spite of the formation of cellulose–EDA complex. This is attributed to a structural hinderance existing in the cellulose molecule itself. There is considerable improvement in the lateral order of the treated cellulose on subjecting it to repeated swelling operations with EDA.
