Abstract

Several cellulosic fabrics such as cotton(plain and jacquard), rayon(plain) and Tencel(twill) are treated with relatively high-concentrated chitosan solution by padding and printing methods. The treated fabrics, both by padding and printing, must have more than 0.5 wt% of add-on of chitosan to get at least 90% bacteriostatic ratio. The moisture regain and deodorization ratio increase with increasing add-on of chitosan, but static charge decreases. These properties occur irrespective of the chitosan treatment method and variety of fabrics. However. air permeability is strongly dependent on the treatment method. In the case of padding process, air permeability increases with increasing chitosan content, but the air permeability of cellulose fabrics treated by printing process decreases with increasing chitosan content. When cellulose fabrics are dyed, dye exhaustion and shade depth increase with increasing add-on of chitosan. Also. cellulose fabrics treated with chitosan have superior colorfastness compared with untreated cellulose fabrics. Especially, cellulose fabrics treated by printing method have excellent colorfastness compared with the padding method.
