  • I reviewed about dyeing fastness and functional properties of the non-mordant dyed cotton and iron mordant dyed cotton with astringent persimmon juice. In the UV-VIS spectrum of astringent persimmon juice, the maximum absorption wavelength of the juice was 272.0 nm, which was a characteristic peak of tannin. In dyeing fastness, light fastness of the non-mordant dyed cotton was a little low at grade 2~3. But by the iron mordant treatment, the light fastness was good at grade 4. Dry cleaning fastness to discoloration and contamination was excellent at grade 4~5 for both the non-mordant dyed cotton and iron-mordant dyed cotton. Their rub fastness were grade 3 and grade 2~3 respectively, in the dry condition, and grade 2~3 and grade 3 respectively, in the wet condition. In the perspiration fastness of the non-mordant dyed cotton, the discoloration from acidity and alkalinity was grade 3~4 and grade 3, respectively, and contamination from acidity and alkalinity was relatively good at grade 4. Meanwhile, in the perspiration fastness of the non-mordant dyed cotton, discoloration from acidity and alkalinity was fair, both recording grade 3~4, and contamination from acidity and alkalinity was very good, both recording grade 4~5. In the ultraviolet protection effect of the non-mordant dyed cotton and iron-mordant dyed cotton, the ultraviolet protection factor was both 50+, both of which showed an excellent ultraviolet blocking effect. And the protection rate of UV-A appeared 98.4% and 99.1%, respectively, and the protection rate of UV-B showed 98.7% and 99.2, respectively. In addition, both exhibited an excellent deodorization rate over 99.9% or more, irrespective of the passage of time. Also, both showed an excellent antimicrobial activity over 99.9% or more against Staphylococcus aureus and Klebsiella pneumoniae.

  • This paper surveys the mordanting and dyeing properties of Rubia akane Nakai appropriate extraction, dyeing and mordanting conditions of Rubia akane Nakai were determined, and the effect of mordanting method on dye uptake and color fastness of the dyed fabric was investigated. The optimum temperature to extract Rubia akane Nakai was during 1 hour in 8$0^{\circ}C$. The effective dyeing temperature and time of silk were 8$0^{\circ}C$, 1hour. The silk fabrics dyed with purpurin appeared red color, with alizarine appeared yellow-brown and with Rubia akane Nakai appeared yellow orange. K/S value of the dyeing fabrics was increased by pre-mordanting treatment. Mordant as Sn and Fe was better than anything else in K/S value. Mordanting treatment method affected color change of the dyed silk. In the case of Rubia akane Ntkai light fastness was increased by Fe and Al mordant treatment, Perspiration fastness of Rubia akane Nakai appeared more than 3 grades geneally. Fastness of abrasion and dry-cleaning appeared mon than 4~5 grades and these fastness improvement were generally effective for post-mordanting treatment.

  • This study optimizes dyeing conditions for polyamide-imide fabric using cationic dyes. Dyeing and fastness characteristics of polyamide-imide fabric were investigated with three cationic dyes and 2-hydroxyacetophenone as a swelling agent under various dyeing conditions such as dye and swelling agent concentrations, dyeing temperature and time, pH of dye bath. The dyeing properties were evaluated in terms of dye exhaustion, K/S value and color fastness. The optimized dyeing temperature and time were $130^{\circ}C$ for 90 min for the dyes. Under weak acidic conditions in the range pH 5 to 7, the exhaustion of cationic dyes could be enhanced leading to higher adsorption. Wash and rubbing fastness properties were generally good, while light fastness was slightly low, which can be attributed to the poor photo-stability of the cationic dyes.

  • A mixed bi-functional reactive dye has been applied to the cotton and the cotton/hemp blend and their dyeing and fastness properties were compared. The cotton/hemp blend exhibited higher exhaustion values and better build-up property than cotton, presumably due to the lower crystallinity. Hence, the reproducibility of dyeing of hemp is expected to be excellent. Fastness properties of reactive dyes on cotton and cotton/hemp blend are found to be almost identical. The results obtained suggest that hemp in cellulosic fabric could be used as an important alternative to universal cotton in cellulose fabrics.

  • Dyeing and fastness properties of a dyeable PP fiber were examined with four different types of disperse dyes. It was found that the dyed PP fiber could be cleared by soaping without using sodium hydrosulphite, and that the heat setting above $140^{\circ}C$ resulted in the melting of the PP fiber. The rates of dyeing and the extents of exhaustion of three primary E type dyes were different with each other, the apparent color strength did not increase with increasing dye concentration, and color fastness to washing was not satisfactory. In the cases of both high wash fastness and high light fastness dyes, the rates of dyeing were slow and the extents of exhaustion were very low. On the other hand, the dyeing rates of three primary S type dyes were similar and the build-up properties were good with good color fastnesses. It might be concluded that the best disperse dyes for the dyeable PP fiber were S type dyes.

  • In this study, UV/vis. spectra of color solution extracted from onion shell and dyeing properties of polyamide fibers such as wool, silk, and nylon were investigated. Also, the effect of mordanting on wash fastness and light fastness was Investigated. The amount of colors extracted was increased with extracting temperature and time. The wavelength of maximum absorption of onion shell extract corresponds to flavonol peak and quercetin peak. Also, spectra of color solution were shifted to longer wavelength at higher pH values. It appeared that the optimum condition of the dyeing of wool, nylon, and silk fabrics with onion shell extract was $60^\circ{C}$ , 30min, and pH 4.0 of dyed bath. Surface colors of the dyed fabrics were different according to the used mordants: Al and Cr mordanted fabrics were dyed in yellowish colors, Cu mordanted fabric in greenish color, Sn mordanted fabric in orange color, and Fe mordanted fabric in khaki color. The mordanting was effective at improving wash fastness and light fastness.

  • This study was conducted to survey the end-use properties of the commercial men's socks. Date were obtained from 16 samples of men's socks gathered from department store, markets, specialty chain and variety store in street. Stretchness, performance of rib top, fiber contents, strength (abrasion and bursting), pilling properties and color fastness of socks tested in this study were as follows. 1. Stretchness of socks was sufficient but elongation of rib top was insufficient, therefore these facts are getting to become problem to consumers. 2. Fiber contents of samples were not in accord with the labelled item and criteria of Textile Fiber Product Identification Act. 3. Strength and pilling properties were vaious in according to fiber contents of socks. Socks blended of synthetic fibers were superior to that pure natural fibers in strength but not in pilling. 4. Color fastness to perspiration and rubbing were sufficient on the whole, but fastness to laundering in stain were very insufficient.
