This study was to investigate the natural dyeing materials in domestic, trials to detect new Inula Britannica. An appropriate dyeing condition ;was bath ratio 1:20, 50% (o.w.f.)conc., $80^{\circ}C$, 50min. The K/S values of silk fabric was the most efficient for the pre-mordanting method. The value of dyed fabric was mostly dark, for the mordanting, the chroma was best clear when using the Cr-mordant, color difference was distinct when using the Fe-mordant. The antimicrobiality of Inula Britannica itself appeared as a 6mm halo zone, dyed fabric was excellent with result of over 90% in mordant. In the case of dye fastness, the drycleaning and wet cleaning fastness was excellent, rubbing and perspiration fastness was improved, and light fastness was over level 2.

enVix is a novel regenerated cellulosic fiber, which is prepared from cellulose diacetate fiber using environmentally friendly manufacturing process. Vat dyeing properties of the enVix were investigated and compared with those ofregular viscose rayon. The enVix exhibited better dyeability than viscose rayon. The colour yields of vat dyes on the enVix were found to be dependent on dyeing temperature as well as the amount of levelling agent and salt. Good build-up and good to excellent fastness properties were obtained on the en Vix fabric.

In this study, we investigated the clean appearance and good stretch properties. Usually, clean appearance concerned with the dyeing properties of core and effect yarns. The dyeing properties between core yarn (conjugate yarn) and effect yarn were determined by the build-up and the color differences using the four different yarns of SDY FD(spindraw yarn full dull), SDY CD(spindraw yarn cation dyeable), POY FD( partially-oriented yarn full dull) and POY CD(partially-oriented yarn cation dyeable). We used the single color dye of C. I. Disperse Blue 79 and mixed colors made by C. I. Disperse Red 60, C. I. Disperse Blue 56, and C. I. Disperse Yellow 54.

Dimethylaminopropyl methacryamide was photografted onto PET fabrics by continuous UV irradiation under ambient conditions. Several factors affecting the photografting were studied including irradiation energy, monomer and photoinitiator concentrations. ATR and ESCA analysis showed the successful grafting of the monomer onto the PET surface. The grafted PET fabrics showed higher zeta potentials below pH 7 compared with the ungrafted PET. The dyeability of the grafted PET fabrics to two $\alpha$-bromoacrylamide reactive dyes was investigated under various dyeing conditions including dye concentration, pH, dyeing temperature and time. The grafting imparted the reactive dyeability to PET fabrics, which was proportional to the grafted monomer content. The reactive dyeing behavior of the grafted PET fabrics was similar to that of conventional wool fabrics.

The fashion industry saw the emergence of environment-friendly and natural fabric materials recently. The naturalism trend has established sectors in the textile and fashion industry also. Ramie and hemp have long been favored fabric materials in Korea especially for summer. The hand-related mechanical/physical properties of the fabric specimens were analyzed using a fabric objective measurement system, KES(Kawabata Evaluation System). Subjective evaluation was also implemented based on a series of selected adjectives. Studies on natural dyeing methods are important since the establishment of scientific approach is needed in terms of environment and human safety along with the reproduction of traditional natural dyeing methods. In this study, linen, ramie, hemp, and cotton/polyester/linen union fabric specimens were used for the natural dyeing using Rubia akane Nakai with the mordant of gallnut. ${\Delta}E$ values of dyed fabric specimens, mordanted and dyed once using Rubia akane Nakai, increased significantly compared to those of repeatedly dyed fabric specimens without mordanting.

This study conducted on the introduction of recycled cellulose fibers, which are widely used in the textile industry as eco-friendly biomass materials, into polypropylene resins, which are mainly used for interior and exterior materials such as door trims and console parts of automobiles. In general, cellulose fibers can affect mechanical properties and have a lightening effect when used as a reinforcing agent. However, since cellulose fibers have hydrophilic properties and have relatively low compatibility with industrial polymer resins, they are used in combination through fiber hydrophobic surface treatment. Therefore, through this study, the reforming reaction conditions optimized in terms of hydrophobicity and workability for cellulose fibers are studied. Furthermore, polypropylene containing surface-modified cellulose fibers was prepared to compare physical properties by fiber content and study optimized content.

In this research, we studied the dyeing properties of PET fibers in terms of $TiO_2$ contents, fiber strength and spinning oil which may cause barre' effect. The effect of $TiO_2$ contents in the fibers had no influence on the dye uptake. However, the reflectance(%) behaviors showed the different visual properties as $TiO_2$ contents in the fibers. The other factors could be considered as strength and spinning oil which also revealed difference on the dye exhaustion. The experimental results showed that $TiO_2$ contents within the fibers influenced reflectance(%) behaviors. Furthermore, fiber strength and spinning oil could be considered other major factors to impart the dyeing irregularity and barre' effect.

The optical and physical properties of alkyl-substituted anthraquinoid dyes were investigated in terms of dyeing of pure polypropylene fiber. The length of alkyl substituents of the dyes did not affect the molar extinction coefficient and maximum absorption wavelength of them. The use of a double-tailed cationic surfactant, didodecyldimethylammonium bromide(DDDMAB), could make the hydrophobic dyes dispersed in water effectively. As the amount of DDDMAB increased, the average particle size of dye dispersion decreased. Maximum color strength of the fabrics was shown in the case that 1.5 molar ratio of DDDMAB was used. As for the fastness properties, commercially acceptable result was obtained in general.

협힐(��纈)은 직물을 두 개 또는 그 이상의 조각한 목판 사이에 끼워 넣은 후 염색하여 무늬를 표현하는 방염(防染) 기법이다. 통일신라 흥덕왕 9년 복식금제(服飾禁制)에는 육두품녀(六頭品女)와 오두품녀(五頭品女)의 여러 가지 복식 품종에 협힐 사용을 금한다는 기록이 있다. 이것으로 미루어보아 협힐 직물이 당시 널리 사용되었으며 협힐 기법도 통일신라시대 또는 그 이전에 완성되었음을 추측할 수 있다. 그러나 문헌 자료에는 용어만이 언급되었을 뿐 염색 기법이나 정의에 대한 내용은 확인되지 않고 유물도 고려시대의 것만 극히 소량 남아 있어 협힐의 유형이나 특징을 알 수 없다. 공예 기술은 각 나라마다 정치 경제 사회 문화 등의 요인에 의해 변화하며 주변국과의 교류를 통해 발전한다. 따라서 본 논문은 주변국인 중국과 일본의 문헌 및 유물을 조사 분석하여 협힐 유형과 특징을 살펴보았다. 이를 통해 협힐은 국가별 특징보다 무늬를 나타낼 때 사용하는 색의 가짓수에 따라 단색(單色)과 다색(多色)으로 나누어지며, 무늬 구조에 따라 단독(單獨) 좌우대칭(左右對稱) 상하좌우대칭(上下左右對稱)으로 분류되는 것을 알 수 있었다. 또한 중국과 일본에서 전승 및 재현되고 있는 염색 기법의 사례를 연구한 결과 직물에 무늬가 잘 드러나도록 하기 위해서는 사용하는 색의 가짓수와 무늬의 특징에 맞추어 협힐판을 양각(陽刻) 투각(透刻) 음각(陰刻)으로 각각 다르게 조각하여야 하는 것을 확인하였다. 우리나라에서 무늬와 색이 온전히 남아 있는 유일한 유물인 1302년 아미타불복장 소화문협힐견을 실험 대상으로 삼고 염색 기법 사례 연구에서 얻어진 기초자료를 근거로 실증적 실험을 통해 협힐 기법을 재현하였다. 본 논문은 추후 계속 연구할 협힐 기법 재현에 활용될 기초자료를 구축하고, 전승되고 있지 않는 협힐 기법의 재현을 시도하여 기법의 특징을 확인한 것에 의의를 두고자 한다. 그리고 현대적인 무늬 염색 기법과 접목시켜 한국적 무늬 염색의 세계를 넓히며 재창조하는 데 보탬이 되길 기대한다.

The aim of this study is to develop an effective dyeing process for black color on the silk fabrics, using natural Indigo, Madder, Amur cork tree, Alder, Logwood, and Gallnut. All natural dye materials were water-extracted, concentrated, and freeze-dried. Seven different processes were carried out and the color differences(${\Delta}E$) of black color with each process from the chemical black dyed fabric were compared. The light, washing, and rubbing fastness were evaluated. The black dyeing of the silk fabrics was well carried and excellent black color was obtained in every methods. The profound black color could be obtained by the subtractive mixture of the three primary colors of red, yellow, and blue in the order of indigo(blue) - amur cork tree(yellow) - madder or lac(red). Black color was efficiently obtained by iron mordant when logwood or alder fruit was used. The color difference(${\Delta}E$) from the black color with chemical dyestuff was the lowest in the indigo - amur cork tree - lac - iron method. Light fastness and washing fastness were excellent in all dyeing processes, showing grade 5. The fastness to rubbing was excellent as shown grade 5 in the dry samples of logwood - iron process and alder fruit - iron process.
