| Abstract: | Reduction in the degree of polymerization (DPn) of a poplin fabric from 2300 to 350 was carried out by two techniques, viz. (i) alkaline hypochlorite bleaching of mercerized-scoured fabric (MS) to give hypochlorite Oxycelluloses, and (ii) acid hydrolysis of mercerized-scoured-peroxide bleached fabric (MSB) to give hydrocellulose. These were crosslinked with DMEU by the pad-dry-cure technique using MgCl2.6H2O as catalyst and further DMEU stripped through urea-phosphoric acid (UPac) hydrolysis. From the study of the strength-abrasion properties of these treated fabrics it was found that (i) the MSB sample undergoes less "total" loss as compared to the MS sample on DMEU crosslinking. However, the MSB sample suffers greater "permanent" loss compared to the MS sample and (ii) hydrocellulose undergo less "total" and "permanent" losses compared to hypochlorite Oxycelluloses at all DPn levels. However, the Oxycelluloses possess better strength-abrasion properties after DMEU crosslinking due to their higher values at the unfinished stage as compared to the hydrocellulose. |
