Abstract

This research was performed to use recycling wood fiber from waste MDF as raw materials for manufacturing of interior decorative accessories. Virgin fiber of Pinus rigida for manufacturing MDF and recycling fiber from manufactured MDF with virgin fiber were dyed by using reactive dyes (Bis-monochlorotriazine and Vinyl sulfone type), vat dyes (Anthraquinone type), direct dyes (Diazo type) such as red, yellow and blue, and natural dyes using gardenia or sappan wood, and they were examined to evaluate their dyeing properties and sunlight fastness. The hue of virgin fiber and recycling fiber were 4.2YR, and 4.4YR, respectively, which showed red-yellowish color. The recycling fiber looked a little darker than the virgin fiber, where $L^*$ values of the recycling fiber showed a little lower. Reactive, vat and direct dyes dyed well both the virgin and recycling fibers. The recycling fiber showed a little higher values of colour yield and a little lower in $L^*$, but it seemed that there was no significant difference. The Hue values of the recycling fiber and the virgin fiber dyed with sappan wood were 4.4YR and 4.0YR, showing no difference between/after dyeing. However the Hue values of the recycling fiber and the virgin fiber dyed with gardenia were 7.4YR and 6.9YR, respectively. Those values were much higher than the values of the fibers dyed with other chemical dyes. But the fibers dyed with gardenia showed poor sunlight fastness.

폐MDF 재생섬유를 인테리어 소품 제조용 원료로 이용하기 위해 MDF 제조용 리기다소나무 버진섬유와 MDF를 제조한 후 재해섬한 재생섬유에 대해 빨강, 노랑 및 파랑색 계열의 Bis-monochlorotriazine (MCT)계와 Vinyl sulfone(VS)계의 반응성염료, Anthraquinone계의 배트염료, Diazo계열의 직접염료 및 치자와 소목의 천연염료에 의한 염색 특성 및 일광견뢰도를 검토하였다. 염색 전의 버진섬유와 재생섬유의 색상은 각각 4.2YR과 4.4YR로 약간의 적색기가 있는 황색을 나타내고 있었으며, 재생섬유가 버진섬유에 비해 $L^*$의 값이 작아 약간 더 어두웠다. 적, 청, 황색계의 MCT계와 VS계의 반응성염료, 배트 염료, 직접염료 모두 버진섬유와 재생섬유에 관계없이 염색은 매우 양호하게 잘 이루어졌다. 재생섬유가 버진섬유보다 염착량은 약간 높았고, $L^*$와 V의 값은 약간 감소하였으나, 큰 차이는 없었다. 일광견뢰도는 염료에 따라 약간의 차이는 있으나 버진염색섬유가 재생염색섬유보다 더 큰 색차를 보이고 있어 불량하였다. 소목으로 염색한 재생섬유와 버진섬유의 색상은 각각 4.4YR과 4.0YR로 염색 전의 미염색 섬유와 거의 차이가 없었으나, 치자로 염색한 섬유의 색상은 각각 7.4YR과 6.9YR로 황색계의 반응성염료, 배트염료 및 직접염료보다 큰 색차를 보여 염색성은 우수하였으나 일광견뢰도는 불량하였다.
