인공사료로 먹인 누에에 천연염료와 화학 염료를 각각 혼합하여 5령 3일째부터 먹인 누에의 유색고치 생산을 검토한 결과 다음과 같다. 1. 천연염료와 인공사료를 혼합 할 경우에 치자 색소만 청자색으로 변환하여 유색 견을 생산하였고 고치의 중량은 대조 보다 낮았다. 2. 화학 염료 혼합 인공사료는 Orang II, Methyl Orang, Acid Blue R의 유색고치 생산은 주황색 노란색, 파란색 순서로 유색 고치를 생산하였다. In order to produce color cocoon, 3rd day 5th instar silkworm was cultivated with dye mixed artificial diet. Silkworm fed by artificial diet mixed with gardenia pigment spun blue colored cocoon, by Orange II orange cocoon, by methyl orange yellowish cocoon, and by Acid blue R bluish cocoon. Cocoon weight and cocoon shell weight ratio of silkworm fed by colored artificial diet were lower than those of normal silkworm.

In general, acid dyes been used for silk dyeing, but acid dyed silk shows weakness in color fastess, To improve this defect, the silk dyed with Acid Mordant Blue 13 was treated with chrome salts solution. Some mechanical properties and dyeing behaviors of the chrome mordant with dyed silk fabric were tested in this work. The tensile strength of silk fabric treated with chrome salts solution was decreased as the duration of treatment was increased. The mean rate constant (K) of photo-degradation was 1.019, and 1.047 after treated with Cr (III) and Cr (Ⅵ), respectively, whereas it was 1.304 in untreatment. The washing fastness of silk fabric also was improved by treatment with mordant and it was 3rd-4th grade and 4th grade when silk was treated with Cr (III) and Cr (Ⅵ), respectively, while untreatment gave 1st grade. The colour of dyed silk fabric was 2.5RP.3/10, but it was 5PB.4/3 and 5PB. 4/4 when the silk fabric was treated with Cr (III) for two hours and with Cr (Ⅵ) for one hour at 90℃, respectively.
환원제 Sodium Hydrosulfite를 이용한 천연쪽의 견 염색효과
정인모 ( Chung In Mo ),우순옥 ( Woo Soon Ok ) 한국잠사학회 2002 한국잠사곤충학회지 Vol.44 No.2
천연쪽 색소를 사용하는 의한 견직물의 염색 방법을 확립하고자 시험결과 환원제인 Sodium Hydrosulfilte를 사용한 경우 염색온도가 30℃에서는 30분, 50℃에서는 10분 염색 한 것이 표면 염착농도(K/S)가 가장 높았고, 염색액의 pH 7.4정도인 환원제 및 염료량을 4g/ℓ일 경우에 가장 높았다. 1회 염색직물의 표면염착농도(K/S)는 개선은 7.20, 기존 염색 방법은 1.09이었으며, 염색 직물의 분리한 색소와 염료색소는 모두 청색색소와 적색색소의 2개의 성분이었고 분자량은 262이었으며, 기존과 개선 모두 정균율은 99.8%이상으로 항균성이 우수하였다. Effect of reducing agent sodium hydrosulfite on the natural indigo on the silk fabrics were examined to improve traditional dyeing method. K/S values of dyed fabrics was monitored with various dyeing temperature time, amount of dye and reducing agent. The dyeability of silk fabrics was improved using reducing agent,k sodium hydrosulfite; K/S value(7.20)was higher then that (1.09) of traditional method at the frist dyeing. Natural indigo dye extracted from dyed silk fabrics are composed of isomer, indigo(67.3%)and indirubin(32.5%). However, silk fabrics showed excellent antimicrobial activity regardless of the dyeing methods.

쪽풀 생잎에서 우려낸 색소 액에 소석회를 첨가한 후 쪽풀 색소의 침전물을 만들어서 냉동 건조시켜 쪽풀 색소를 제조하여, 그 성분을 조사한 결과 다음과 같은 결론을 얻었다. 1. UV 분광광도, TLC 정성 분석, HPLC 측정 결과 쪽분말 용액의 2개 bend가 나타났으며, 적색색소대인 540nm 와 청색 색소대인 620nm가 존재함을 알 수 있었다. 2. FT-IR 분석으로부터 1627cm-1에서 채, 320~3300 cm-1에서 NH의 흡수대가 나타나고, 적색 및 청색 색소의 IR spectrum이 일치하였으며, 3. EI-mass 분석 결과 청색과 적색 색소의 fragment 이온의 m/z가 일치하고, 1H_MNR 분석결과로부터 두 색소는 이성질체임을 알 수 있었고, 4. 쪽 염료 성분 함량을 조사한 결과 인디고 색소 4.06%와 인디루빈 1.06%이었다. Natural indigo colorants were prepared by extraction of Polygonum tinctorium which was harvested just in the blooming season (in the late of July). The components were analyzed by TLC and HPLC, and its structures were analyzed by FT-IR, El-mass. The results obtained are summarized as follows; The natural indigo powder was dissolved in DMSO and developed in eluent, CHCI3/CH3CN (8.5: 1.5 v/v) by means of TLC for its quality analysis. It was segregated into indirubin as a red colour and indigo as a blue colour. In case of HPLC analysis,. FT-IR spectrum of indirubin showed a peak for NH residue between 3200 and 3300 cm-1. ``H-NMR spectrum for indigo displayed AA``BB`` spin system caused by indole structure between 6.5 and 7.7 ppm of H4, 5,6 and 7, and -NH proton for indirubin showed an singlet between 10.88 and 11.0 ppm. EI-mass spectrum of indigo and indirubin both disclosed their molecular size as 262 and it implies that these two substances are isomer.
