초극세 나일론 6 섬유의 염색성 및 물성에 미치는 열처리의 영향

Effect of Heat Treatment on Dyeing and Physical Properties of Nylon 6 Ultramicrofiber

  • 발행 : 2002.12.01

초록

Nylon 6 staple ultramicrofiber(UMF, 0.074) and regular staple fiber (Regular, 2.0d) were annealed at In, 130, 160 and $180^\circ{C}$ under tension free for 10 min and U min. The treated fibers were dyed with Acid Red 18 and Blue n3. They were adjusted at PH 5.0 of dye bath in buffer solution of $CH_3COOH/CH_3/COONa(0.1mo1/1)$. Liquor ratio was kept at 1000:1. Dyeing rate of UMF annealed at $100^\circ{C}$ was decreased, but was increased for regular nylon. Also dye equilibrium of UMF at $100^\circ{C}$ was increased for Acid Red 18, but was decreased for Acid Blue 83. The intensities of X-ray diffraction peaks of UMF increased with increasing annealing temperature. Also the crystallinity of heat-sotted fibers by DSC thermogram was well agreed with the tendency of density Amino end group, moisture regain and water absorbency were decreased with increasing annealing temperature.
