Silk fabrics were dyed with yellow natural materials. Gardenia, turmeric, amur cork tree, safflower, Japanese pagoda tree, and onion were used as natural materials. Color image of natural dyed silk fabrics was classified by 4 factors(Cheerfulness, Comfortness, Pastrol, Revealation). Cheerfulness factor affected significantly with color image. Amur cork tree or turmeric dyed fabrics were shown as light and cute, safflower or gardenia dyed fabric shown as comfort, and onion dyed fabrics shown as mature and simple. Color image with specialty was significant difference in Preference and Revelation factor. Preference was appeared as amur cork tree>turmeric>gardenia>safflower>Japanese pagoda tree>onion.

This study investigated color change of combination dyeing silk fabrics dyed with Turmeric extracts and Gardenia extracts after dyeing of Indian indigo. Experimental variables include the condition of dyeing time and concentration of Turmeric extracts, Gardenia extracts, arid dyeing cycle of Indian indigo. Surface color of silk fabrics dyed with Turmeric 77tracts after one cycle dyeing, two cycles dyeing, four cycles dyeing of Indian indigo was changed from 5.1GY to 0.3GY, 1.5G to 3.5GY and 6.5G to 5.8GY by increase of concentration of Turmeric extracts. On the other hand, Surface color of silk fabrics dyed with Gardenia extracts after one cycle dyeing, two cycles dyeing, four cycles dyeing of Indian indigo was changed from 7.5Y to 3.9Y, 1.2GY to 6.7Y and 4.0GY to 8.6GY by increase of concentration of Gardenia extracts. Its range of surface color was changed to green and yellowish green by increase of dyeing time with concentration of Turmeric extracts. On the other hand, its range of surface color was changed to yellowish and yellow by increase of dyeing time with concentration of Gardenia extracts.

Mercerization of cotton fabrics affects their various properties including physical properties and dyeing behavior. In this study, the concentration levels of NaOH solution, with 18% and 25%, and the mercerization temperature levels, $22^{\circ}C,\;10^{\circ}C$, and $5^{\circ}C$, were changed in order to investigate the physical properties and dyeing behavior using Gardenia, a natural dyestuff, and direct dyes. The effect of tension during the mercerization was also investigated. In order to investigate the dyeing behavior of Gardenia, a direct dyestuff was employed as a comparative material for better objective analysis and evaluation. It was found that the mercerization condition of 18% NaOH concentration at $10^{\circ}C$, without tension, resulted in the highest ${\Delta}E$ value, when dyed with Gardenia.

The purpose of this study is to investigate the dyeability, and the hand of soybean/cotton blended fabric after dyeing with natural and synthetic dyes. Soybean/cotton blended fabrics dyed with extracted solution from turmeric, sappan wood, gardenia and synthetic dyes(weak-acid dyes, reactive dyes, direct dyes). The hand value of soybean/cotton blended fabrics dyed with 6 different dyes was measured using Kawabata Evaluation System. The results are as follows; 1. The K/S value of the soybean/cotton blended fabric dyed with sappan wood extracts was the highest. 2. The color fastness of the soybean/cotton blended fabric dyed with reactive dyes was excellent. The fastness to the light of the same fabric was much better than the other fabrics. 3. Linearity of load-extension and tensile energy of the soybean/cotton blended fabric dyed with sappan wood extracts showed very high. Shear stiffness of the soybean/cotton blended fabric dyed with weak-acid dyes was much higher than that of fabric of dyed with reactive dyes. Bending property of the fabrics dyed with natural colorants(sappan wood, gardenia) showed very high, but that the fabric dyed with reactive dyes was very poor. 4. In the primary hand value, stiffness and anti-drape stiffness of the fabric dyed with weak-acid dyes showed the highest. Fullness and softness of the fabric dyed with weak-acid dyes showed very low.

This study explores the effects of X-ray irradiation for biological control and high-temperature degradation on dye stability in dyed textiles with Gardenia. To evaluate this study, optimal extraction solvents for these textiles were identified by comparing them with a crocin standard solution. Extraction using pyridine closely matched crocin. The study then assessed the stability of X-ray irradiation and high-temperature degradation on these textiles. Transparent yellow dyes were observed in all samples. Color differences were found to increase at higher irradiation doses and longer degradation periods. While UV spectroscopy spectra showed broadening and lowering trends with higher irradiation doses and longer degradation periods, suggesting a reduction in colorant transition, mass spectrometry revealed minimal chemical changes. In conclusion, both X-ray irradiation and high-temperature degradation induced spectral changes without complete dye decomposition. Major colorants were consistently detected.

본고는 우리나라 청색계 염재인 쪽과 황색계 염재인 울금, 치자, 황련, 황벽으로 염색한 청색, 녹색계열의 직물편에 대한 비파괴 자외-가시광 분광 분석 및 3차원 형광 분광 분석 내용이다. 직물의 종류에 따라 각 염재의 분석결과에 영향을 주는지 여부를 확인하기 위하여 견과 면에 염색한 직물시편을 제작하였다. 염색 직물편에 대한 자외-가시광 반사도 측정 결과 쪽으로 염색한 경우 직물의 종류에 관계없이 쪽의 고유한 반사 스펙트럼이 나타났다. 녹색 계열의 직물은 3차원 형광 분광 분석결과 직물의 영향없이 황색 염재인 울금, 황련 및 황벽의 고유한 형광 스펙트럼이 확인되나 치자 및 쪽의 형광 스펙트럼은 나타나지 않았다. 이와 같은 결과는 견이나 면에 염색된 청색 및 녹색 염료의 종류를 규명하는 자료로 활용할 수 있을 것으로 판단된다.

견직물 시료에 치자, 소목 염색을 행한 후, 자외선에 0일, 14일, 21일, 28일 조사 시킨 후 시간의 경과에 따른 시료들의 염착량, 색채 변화, 형태 변화, 인장강도 그리고 화학적 변화를 관찰한 결과 다음과 같은 결론을 얻었다. 1. 염재의 종류와 매염 여부와 관계없이 자외선 조사 초기 14일 동안에는 염착량이 서서히 감소하다가 그 후에는 급격한 감소를 보였다. 명반 매염을 한 경우 염착량 감소가 더 적었으며 소목이 치자보다 자외선 차단 효과가 더 우수한 것으로 나타났다. 2. 자외선 조사 시간이 길어짐에 따라, $L^*,\;a^*,\;b^*$, H V/C, ${\Delta}E$ 등은 급격한 변화와 퇴색경향을 보였으며 명반 매염제가 자외선에 의한 탈색을 방지해 주는 역할을 하는 것으로 나타났다. 또한 치자보다 소목의 ${\Delta}E$값이 낮게 나타났는데 이는 염착량 변화의 결과와 일치하며 소목이 치자보다 자외선 차단 효과가 더 우수한 것으로 나타났다. 3. 염색 견직물 시료들 모두 자외선 조사 시간 경과에서, 초기에는 섬유 표면의 피브릴 분리현상을 보였으며 조사 시간 증가에 따라 섬유 표면이 더 깊고 두껍게 박리되어 손상이 심해졌으나 SEM 측정에서는 두 염료의 매염제 처리 유, 무의 차이는 발견하기가 힘들었다. 4. 자외선 조사에 따라 인장강도는 자외선 조사 14일 이후부터 감소되어 인장강도 감소율은 대략 5-20%의 유지율을 나타내었으며 매염 처리 시료의 인장강도 감소율이 더 낮았다. 5. FT-IR 분석에 의하면 자외선 조사 시간 증가에 따라 치자와 소목 주 피크들은 사라지고 견섬유의 주 피크만이 확인되었다.

Melange yams were prepared by varing the ratio of raw cotton dyed with Indigo, Gardenia and Sappan wood colorants, respectively. The antibacterial activity and deodorization on melange yarns were evaluated for bacteria reduction rate and deodorization rate. The bacterial reduction rate on melange yarns was explored with Staphylococcus aureus, Klebsiella pneumoniae. The melange yarns on the ratio of raw cotton dyed with Sappan wood and Indigo showed high Staphylococcus aureus reduction rate of 99% and 90%, regardless of Al-mordanting treatment, but those with Gadenia hardly showed bacteria reduction rate. The melange yarn showed high Klebsiella pneumoniae reduction rate of 99% for Al-mordanting treatment with Sappan wood. The others were poor. The deodorization of 81% and 98∼99% obtained with melange raw sliver and melange sliver dyed with Indigo, Gardenia and Sappan wood colorants, but dyeing did not significantly affect deodorization rate.

The aim of this study was to impart color to bacterial cellulose (BC) fabric using various natural plant-based dyes-namely, gardenia jasminoides, green tea, and pomegranate peel. A protein pretreatment was also applied to improve the BC fabric's dyeability and mechanical properties. The BC fabric's dyeing and mordanting conditions when using plant-based natural dyes were determined by changes in the K/S values. The dyeability of BC samples dyed with green tea or pomegranate peel improved when they were pretreated with soy protein isolate (SPI) prior to dyeing. Moreover, the SPI pretreatment was efficient in improving the BC fabric's tensile strength and flexibility. This study proposes a method for dyeing BC fabric that uses plant-based natural dyes and confirms the effects of the protein pretreatment on the fabric's dyeability and durability.
