“…Al, Fe, Cu, and Ti were used as metal mordants, while thiourea and tannicate (tannic acid) were used as organic mordants. We ran a pre-mordanting test for multifiber fabrics [18]; the results for silk fiber are shown in Table 3. Dye uptake (K/S) differed depending on the type of mordant.…”

“…Aluminum potassium sulfate (AlK(SO 4 ) 2 ·12H 2 O), ferric sulfate (FeSO 4 ·7H 2 O), cupric sulfate (CuSO 4 ·5H 2 O), and titanium (IV) sulfate (Ti(SO 4 ) 2 ) were used as metal mordants, while thiourea (H 2 NCSNH 2 ) and tannic acid were chosen as organic mordants. At first, the multifiber fabrics [18] were premordanted with a mordant concentration of 3 % (owf) in a 1:50 bath ratio at 30 o C for 30 min. The pre-mordanted fabric was then dyed using a dye concentration of 0.2 % (owf) at 30 o C for 30 min.…”

“…This study drew upon the available research on the dying properties of microbial prodiginine [18] and explored the possibility of using the red microbial colorant to dye fabrics. For this purpose, we used the red colorant from Zooshikella rubidus to dye silk, which was chosen because it can be dyed by a red colorant very easily and quickly.…”

The dyeing properties of prodiginine from Zooshikella rubidus for silk fabrics have been studied. Prodiginine was extracted from microbial cells with 100 % ethanol. Optimal silk dyeing was carried out using an infrared dyeing machine at 60 o C for 60 min, at 1.0 % (owf), using a 1:50 bath ratio at pH 4.0. Optimal concentrations of Al and Ti mordants in silk dyed with microbial red colorant were 2.0 and 1.0 % (owf), respectively, as determined by dye uptake (K/S). Color fastness to washing, water, rubbing, perspiration, and dry cleaning was measured as grades 3-5. However, light fastness was grade 1, similar to that for other natural dyes. When Al and Ti mordants were used on silk, fastness to washing and perspiration was improved by more than 1 grade.

This study was investigated trends and consumer awareness on cycling pants by analyzing the reviews on bib shorts, bib tights, shorts, and tights in online shopping malls using text mining. The reviews and product information on cycling pants from Jan. 2017 to the first half of 2020 were crawled, and a total of 7241 cases were analyzed. The keywords of cycling pants were extracted using a Korean morphological analyzer (KoNLP), calculated to the term-document matrix, and then converted into a co-occurrence matrix. The number of reviews of cycling pants increased by 39% per year, and especially in the first half of 2020, the number of reviews has doubled over compared to the first half of last year. Bib shorts accounted for more than 50% of the number of reviews of cycling pants and received the highest rating, making them the most preferred. Positive reviews on cycling pants appeared 15 times over than that of negative reviews, and most of the cycling pants were evaluated positively. Size and cost-effective appeared as the important keywords both in positive and negative reviews. However, it was found that consumers have a difficult time choosing the size not only in the negative but also in the positive reviews. Pad was the keyword that appeared the most in negative reviews, and it was the most dissatisfied factor in the cycling pants. Therefore, in an internet shopping mall, it is necessary to provide intuitive and accurate information that is easy for consumers to understand about information on the size and pad of the cycle pants.
