This paper reports the effects of bleaching of alpaca tops and dyeing of bleached alpaca tops/yarns on the quality of tops and yarns. A dark brown alpaca top was bleached with hydrogen peroxide. Two bleaching methods were tried for effectiveness of color removal. A portion of each bleached top was dyed after bleaching. Color parameters were examined for unbleached, bleached and bleached/dyed tops, these tops were then converted into yarns of different twist levels and counts using a worsted spinning system. Some of the bleached yarn from each bleaching method was dyed in a package dye vat to compare the difference of top dyeing versus yarn package dyeing on yarn quality. Fiber diameter, yarn strength, yarn evenness, yarn hairiness and fiber degradation were tested to examine the effects of bleaching and dyeing on these properties at top and yarn stages. A processing route for bleaching and dyeing alpaca fiber was recommended.

This study explores the culture surrounding the dyeing of royal garments in the late Joseon Dynasty. The findings of this study are as follows. First, several dyes were used to color royal garments, such as jicho, honghwa, danmok, simhwang, sambo, goehwa, chija, and namjong. Mordants such as maesil, hwanghoemok, yeohoe, and baekban were also used with the dyes. Second, the Sangeuiwon (尙衣院) was the department in charge of the purchasing of dyes and the entire dyeing practice. It was the Seonhyecheong (宣惠廳) and the Hojo (戶曹) who provided revenue to the Sangeuiwon through a wongong, regular tribute, and a bokjeong (supplementary tribute). Additionally, additional dyes, if found to be insufficient, could be provided by the Hojo. Every year the Hojo provided jicho, honghwa, and danmok to the Sangeuiwon, and sometimes imported namjong from China. Third, royal garments were, in most cases, dyed by the Sangeuiwon's professional dyers and court ladies belonging to the sewing department in each palace. Naenongpo (內農圃) eunuchs were in charge of the indigo crops of each palace. Finally, more dye was used in royal garments than in the clothes of commoners to obtain a deeper shade of color. In addition, dyers tried to achieve a clear and vivid tone in their garments. Silk which absorbed color relatively easily, was dyed inside the palace using an ice vat filled with fresh indigo leaves; however, cotton was difficult to dye and was sent to professional indigo dyers outside the palace.

PVC를 염색하는 방법에는 분산염료, vat 염료, 함금속염료, 산성염료 등이 보고되고 있다. 그러나 PVC는 의류용 사로 적용되는 예가 적기 때문에 이의 염색에 대한 연구 결과도 상대적으로 드물다. 가발용 사를 만드는 공정의 경우 PVC 방사 시 안료를 배합해 유색 PVC를 얻는 방법에 대한 문헌이 약간 있을 뿐 PVC의 염색에 관한 자료는 거의 찾아보기가 힘들다. 최근 PVC 사의 용도가 다양해지고 있고, 가발용 원사로 이용되는 경우 안료를 배합한 방사법만으로는 two tone colour 등 가발용 원사로서의 다양한 요구에 부합되지 못하므로 후염색에 의해 PVC를 염색하는 방법의 필요성이 요구된다.

Indigo is utilized in various industries including textile dyeing, cosmetics, printing and medicinal products and its reduced form, leuco-indigo, is mainly used in these process. Chemical reducing agent (sodium dithionite, sodium sulfide, etc.) is preferred to use for the formation of leucoindigo in industry. In traditional indigo fermentation process, microorganisms can participate in the reduction of indigo and thus it has been known to reduce environmental pollution and noxious byproducts. However, in fermentation method using microorganisms it is difficult to standardize large scale production process due to low yield and reproducibility. In this study, we attempted to develop the indigo reduction process using microbial flora which was isolated from naturally fermented indigo vat or deduced by metagenomic approach. From the results of library analyses of PCR-amplified 16S rRNA genes from the traditional indigo fermentation vat sample (metagenome), it was confirmed that Alkalibacteriums (71%) was distinctly dominant in population. Some strains were identified after confirming that they become pure culture in nutrient media modified slightly. Four strains were separated in this process and each strain showed obvious reducing ability toward indigo in dyeing test. It is expected that the analyzed results will provide important data for standardizing the natural fermentation of indigo and investigating the mechanism of indigo reduction.

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.

The near infrared ray camouflage fabric has a near infrared ray reluctance similar to the surrounding environment and has a camouflage effect on the surrounding environment. Synthetic fibers used in military uniforms are difficult to have gastrointestinal function as general commercial dyes, unlike cellulose fibers, which use some commercial vat dyes to impart infrared gastrointestinal function. In this study, we optimized the adsorption pH, temperature and time for NIR dye application for polyester fabrics, and established the optimum concentration for the evaluation of adsorption build-up characteristics. In addition, it is difficult to adsorb it since the polyester material has a dense crystal structure and the NIR dye is bulky. Therefore, a swelling agent used for dyeing meta-aramid fibers with high Tg and high crystallinity was introduced as a separate preparation to increase the affinity to polyester, which is a hydrophobic fiber, to thereby obtain an excellent adsorption rate. As a result of comparing before and after using swelling agent, the adsorption rate difference was 10 times or more when compared with before.
