BTCA로 방추가공한 면직물의 수착 성질 및 물리적 성질의 연구

A Study on the Sorption and Physical Properties of the BTCA Finished Cotton Fabrics

Cotton fabrics were treated with BTCA, which is used to improve the wrinkle recovery property of cotton fabrics. BTCA, with varying its concentrations, was treated on cotton fabrics by pad dry-cure technique. BTCA contents in treated cotton fabrics were determined by the weight gain and the FT-lR spectrometer. The effects on the sorption and physical properties of BTCA treated fabrics were investigated. IR spectra showed that ester-crosslinks were produced in BTCA treated cotton fabrics. And as increasing the concentration of BTCA, ester-crosslinks are increased in amorphous regions of fabrics. Moisture regain and water imbibition of treated fabrics were reduced. But, they were increased over a certain concentration. Dye sorptions also were reduced, but they were similar over 6% BTCA. When BTCA was treated on cotton fabrics, DP rating and wrinkle recovery angle were improved. On the other hand, strength retentions of treated fabrics were lower than untreated fabrics. Stiffness was increased.
