Description:
<p class="MsoNormal" style="text-align:justify"><span style="font-size:12.0pt;line-height:107%;font-family:"Times New Roman","serif"">Wool fabrics havingtemperature sensitive shape memory effect were fabricated by using a shapememory polyurethane (SMPU) treatment. The contribution of SMPU treatment onbagging recovery and felting shrinkage, crucial properties for end useperformance, was investigated by a test procedure including hot waterconditions simulating laundry of garments according to the Woolmark TM31standard. Chemical and morphological analyses, bending rigidity, and tearstrength tests were also carried out to determine the effects of SMPU treatmenton performance properties. SMPU treatment significantly increased weight andrigidity of fabrics. Most notably, SMPU treated wool fabric exhibited excellenttemperature sensitive bagging recovery stimulated by a washing procedure. Also,anti-felting and weight loss performances were quite high compared to raw andcommercial polyurethane-treated fabrics.<o:p></o:p></span></p>
