Methacrylamide graft polymerization on silk fibroin dyed with reactive dyestuffs

반응염색견(反應染色絹)의 Methacrylamide graft 중합(重合)

Fixation rate of reactive dyes on silk fibroin showed the same tendency to absorption rate. Fixation rate of Yellow 179 and Blue 71 was quite slow and Black 5, Blue 49, Blue 4, Blue 19 and Blue 21 was relatively fast. Weight increase by MAA graft polymerization onto filk fibroin was decreased, on the whole, according to the the increase of dye fixation, but weight increase of silk fibroin dyed with Blue 71 and Blue 21 was much higher than that of silk fibroin. And weight increase of silk fibroin dyed with Yellow 179 was similar to that of silk fibroin and in case of Blue 19, weight increase was about 12%, constantly. Weight increase of silk fibroin dyed with Blue 71 and Blue 21 was higher and the others were lower than of silk fibroin. And weight increase was diminished according as the dyeing temperature rises. The color was a little changed by MAA graft polymerization.

반응염색(反應染色) 견(絹) fibroin의 graft 중합(重合) 거동(擧動)을 알아보기 위하여, C. I. Reactive Yellow 179, Red 2, Black 5, Blue 13, Blue 49, Blue 4, Blue 19, Red 6, Blue 71, Blue 21로 견(絹) fibroin의 염착량(染着量)이 각각 다르게 염색(染色)하고, methacrylamide graft 중합(重合)하였으며 그 결론(結論)은 다음과 같다. 1. 염료(染料)의 고착속도(固着速度)는 흡착속도(吸着速度)와 일치(一致)하는 경향(傾向)이었으며, 고착속도(固着速度)는 Yellow 179 및 Blue 71이 가장 낮았고, Black 5, Blue 49, Blue 4, Blue 19, Blue 21은 비교적 빠른 것으로 나타났다. 2. 염색시간(染色時間)이 경과(經過)할수록 즉(卽), 염착량(染着量)이 증가(增加)할수록 증량율(增量率)은 감소(減少)하는 것으로 나타났으나, Blue 71 및 Blue 21 염색(染色) 견(絹) fibroin의 증량율(增量率)은 염착량(染着量)의 다소(多少)에 관계없이 현저하게 높았으며, Blue 19의 경우 증량율(增量率)은 12% 내외(內外)로 일정(一定)하게 나타났고, Yellow 179 염색(染色) 견(絹) fibroin의 증량율(增量率)은 무처리(無處理) 견(絹) fibroin과 비슷한 것으로 나타났다. 3. 평형염색(平衡染色) 견(絹) fibroin의 증량율(增量率)은 Blue 71 및 Blue 21 염색(染色) 견(絹) fibroin의 경우를 제외하고는 모두 무처리(無處理) 견(絹) fibroin에 비하여 낮은 것으로 나타났으며, 염색온도(染色溫度)가 상승(上昇)할수록 증량율(增量率)은 저하(低下)하는 것으로 나타났다. 4. Graft 중합(重合) 과정에서 색상(色相)이 다소(多少) 변화(變化)하는 것으로 나타났다.
