홍화 황색소의 면, 마, 레이온과 같은 셀룰로오스 섬유에 대한 염착량을 증진시키기 위하여 키토산 전처리를 행하였다. 키토산 전처리가 염착성, 색상, 염색견뢰도에 미치는 영향을 조사하였다. 섬유 종류에 관계없이 키토산 전처리는 염착성을 증진시켰으며, 농도가 증가함에 따라 계속 증가하였다. 2% 처리농도에서 미처리와 비교할 때 면은 5.6배, 모시는 7.2배, 레이온은 3.7배 염착량이 증가하였다. 키토산 전처리한 면과 모시는 YR 색상에서 Y 색상으로 변화하였으며, 레이온의 경우에는 전처리와 상관없이 Y 계열의 색상을 보였다. 키토산 전처리에 의해 색상은 노란색이 강하여졌으며 더 진하고 깊은 색상으로 변하였다. 키토산 전처리 직물은 염색온도에 따라 색상이 변화하였는데 공통적으로 50, $70^{\circ}C$에서는 YR 색상을 30, $90^{\circ}C$에서는 Y 색상을 나타냈다. 염색온도가 높을수록 색상은 진하고 칙칙하였다. 세탁견뢰도는 아주 낮았으며, 일광에 매우 약한 홍화 황색소의 특성을 고려할 때 일광견뢰도는 양호한 편이었다. 기존의 자동 염색기로 염색하는 경우와 비교할 때 초음파 염색법이 면과 모시의 염착량을 30% 이상 증진시키는 효과가 있음을 확인하였다. 레이온의 경우, 두 방법간의 염착량 차이는 없었다.

In this paper, the dyeing ability of the volcanic ash dyeing on cotton knitted fabrics were investigated. Acrylic copolymer was used to improve the depth of fabric color in the dyeing process. K/S values of dyed fabrics were measured to examine the dyeing properties. Two different classes of dyeing process were tested; (1) volcanic ash dyeing after pretreatment and (2) simultaneous co-treatment with volcanic ash and acrylic copolymer. In the first process, the effects of parameters such as the concentration of volcanic ash, concentration of Na2S04, dyeing time, dyeing temperature and pH of dyebath were noted. In the second process, the effects of parameters such as concentration of acrylic copolymer, dyeing time and temperature, and drying temperature were noted. Experimental results showed that the co-treatment of acrylic copolymer improved the dyeing properties of cotton knitted fabrics with volcanic ash. For the first dyeing experiment, concentration of dispersing agent was 0.1%, concentration of volcanic ash was 4%, treatment time was 20minutes, concentration of $Na_2SO_4$ was 2%, treatment temperature was $60^{\circ}C$ and treatment pH of dyebath was neutral. In the second dyeing experiment, concentration of acrylic copolymer was 2%, treatment temperature was $80^{\circ}C$, treatment time was 40 minutes, and treatment drying temperature was $150^{\circ}C$.

In this study, in order to compare a Tencel/cotton and a Tencel/Cotton/PET as Tencel blended fabrics with a Tencel fabric, the fabric samples were treated with chitosan after NaOH pretreatment and enzyme treatment thereof, And then its adherent efficiency was enhanced by using a crosslinking agent. After that, it was treated with a softener. In chitosan treatment, the functions of moisture regain, tensile strength, air permeability and crease resistance were more improved in the Tencel blended fabrics than in the Tencel fabric. Thus, it may be thought that the physical properties of the Tencel blended fabrics were more effectively modified than those of the Tencel fabric. And the friction charged voltage was very much reduced in all samples, so that chitosan treatment was effective for prevention of electrostatic charge. Further, chitosan finishing treatment improved remarkably the antibacterial activity in all samples regardless of the type of strains.

This research investigated the dyeing behavior of palmatine (a major coloring compound of Phellodendron bark in addition to berberine) using mercerization (M), tannic acid (T), mercerization-tannic acid (MT), and tannic acid -mercerization (TM) pretreatments. Mercerization was conducted using $20^{\circ}C$ of 20% NaOH for 5 minutes. Tannic acid treatment was conducted using 15% o.w.f. solution of tannic acid at $60^{\circ}C$ for 30 minutes and fixed with potassium antimonyl tartrate trihydrate. Dyeing was conducted using 1% o.w.f. palmatine chloride hydrate with 1:100 liquor ratio at $10-95^{\circ}C$ for 10-60 minutes in a dyebath of pH 3-9. MT method resulted in the highest dye uptake and was two times higher than the average dye uptake of T method. MT method provided the best result when the dyeing temperature was $80^{\circ}C$ or $95^{\circ}C$ and the dyeing time was 60 minutes. The pH of the dyebath had less effect on the dye uptake but a pH higher than 5 provided better results. The study confirmed that palmatine is a major coloring compound of Phellodendron bark and that the MT method can be used as a successful cotton dyeing method.

In the direct digital textile printing process, the pre-treatment process is an essential condition for products by forming a clear pattern by sticking and penetration of DTP dye without spreading on the fabric. Recently, pre-treatment agent is changing from high viscosity to low viscosity in order to reduce defects of fabric during pre-treatment process. In this study, pre-treatment agent of acrylic polymer with low viscosity(less than 50cps) was prepared according to the solid content of the polymer, pre-treated on the cotton fabric, and direct DTP printing was performed to compare the color and sharpness. As a result, it showed high color at a viscosity of 50cps or less. When the solid content of the polyacrylic acid having a high molecular weight(A1) was 2.5wt%, when the solid content of the polyacrylic acid having a low molecular weight(A2) was 1 - 1.5wt%, the color was the best. And when the solid content of A1 and A2 was 1.5wt%, the degree of spreading was small and A1 was superior to A2 at the sharpness.

본 연구에서는 현재 항균제, 세정제 및 살균제의 형태로 가장 많이 사용되는 물질 중 하나인 트리클로산에 대한 전처리 방법 및 정량분석 방법을 확립하기 위한 기초적인 연구를 수행하였다. 노말헥산을 추출용매로 하여 속실렛 추출기에서 8 시간 추출할 경우, 가장 높은 추출효율을 보였으며, 분석장비는 GC-ECD와 GC-MS 모두 양호한 분석결과를 보였다. 본 연구에서 조제한 종이 여과지 시료 및 솜 시료를 각각 30 개씩 분석한 결과, 높은 트리클로산 추출효율, 낮은 분석 편차, 일원배치법에 따른 분산분석 결과를 고려할 때, 본 연구에서 조제한 시료 및 본 연구에서 제시한 추출 및 분석방법은 종이 및 섬유시료 내 트리클로산 분석에 유효하게 적용할 수 있을 것으로 판단되었다.
