 Full text | Abstract: Desized and scoured hemp, ramie and linen fabrics were treated with liquid ammonia over practical ranges, followed by crosslink finishing with modified DMDHEU (Clariant Chemical Co). Appearance qualities, as well as comfort and mechanical properties were measured to investigate the wear behavior of all-cellulosic fabrics. The crease recovery, washing shrinkage and other appearance qualities of cellulosic fabrics were improved by NH3 treatment and especially by liquid ammonia pretreatment in conjunction with crosslink finishing. The moisture regain of the cellulosic fibers was increased by NH3 treatment, but on the other hand, water retention was decreased. The air permeability, moisture permeability and other comfort properties of the cellulosic fabrics were decreased by crosslink finishing, whereas those of NH3/crosslinked fabrics were greater than untreated ones. As a pretreatment for crosslink finishing, liquid ammonia significantly improved the tensile strength retention and tear strength in cellulosic fabrics compared to crosslink finishing alone. |
