• For pad-diy-cure(PDC) method, samples were padded with solution containing DMDHEU(5% o.w.b.) and catafyst(0.5% o.w.r. citric add and 2.5% o.w.r. aluminum sulfide), dried at 100℃ for 3 min, cured at 160℃ for 3 min, and washed for further evaluation. For wet-fixation(WF) method, the padded fabrics were sealed in polyethylene bag and stored at 80℃ for 20 min, dried, and cured at the same conditions as in PDC method.
• For scanning electron microscopy(SEM, JEOL JSM 5400), samples were sputtered with gold/palladium and were examined to determine changes in surfeices.
• In this study, Tencel fabrics were crosslinked with a DP finishing agent, dimethylol dihydroxye­ thylene urea(DMDHEU), by using pad-±y-cure (PDC) and wet-fixation(WF) method before cellulase treatment for fibrillation control. Also, NaOH pretreatment was done to investigate its effect on strength retention during DP finishing.
• Performance properties were evaluated by standard procedures including tensile strength, ASTM D-1682-64; tear strength by Ehnendarf tester, ASTM D-1424-83; wrinkle recovery angle, AATCC 66-1990; DP rating, AATCC 124-1967. All the tests except wrinkle recovery angle were conducted in the warp direction.
• Also, NaOH pretreatment was done to investigate its effect on strength retention during DP finishing. The effects of DP finishing method and NaOH pretreatment on performance properties, surface change, medianical properties, and hand were investigated.
