DP가공방법이 효소처리한 텐셀직물의 태에 미치는 영향

Effect of DP Finishing Process on Hand of the Cellulase Treated Fabrics

Tencel^Ⓡfabrics were crosslinked with DMDHEU by pad-dry-cure(PDC) and wet-fixation(WF) method after cellulase treatment. NaOH was pretreated before cellulase treatment in PDC method. DP/performance properties. SEM analysis, mechanical properties and hand value of the treated fabrics were investigated. Crosslinking was increased DP rating and WRA, and decreased breaking and tear srtength retention Especially. PDC method imparted better balance of DP/performance properties than WF method. NaOH pretreatment imparted higher strength retention than non-treatment. SEM analysis showed no significant difference in surface change of the fiber depending on the treatment method of DMDHEU. Regardless of NaOH pretreatment and treatment method of DMDHEU, shear and compressional properties were decreased and surface properties increased by crosslinking. NaOH pretreatment was increased bending and shearing properties, decreased surface properties. Consequently, NaOH pretreatment increased Koshi, WF method provided superior Numeri, Regardless of NaOH pretreatment and treatment method of DMDHEU, crosslinking reduced Fukurami. The best THV was produced by WF method.
