PET fabrics were photografted under continuous UV irradiation with vinyl pyrrolidone (VP) and acryloylmorpholine(ACMO) as monomers and benzophenone as a hydrogen-abstractable photoinitiator. ACMO can be grafted onto the PET fabrics more efficiently than VP. The grafted PET surfaces were characterized by ATR, ESCA, SEM and zeta potential measurement. ATR and ESCA analysis indicated significant alterations on chemical structure and atomic composition on the surface of the grafted fabrics, where nitrogen content increased with increasing grafting yield. SEM images showed that the fabric surface was covered with the grafted polymers. The zeta potentials and the water wettability of the grafted PET increased with grafting. Also the photografted fabrics showed an increased dyeablity to reactive dyes and increased affinity to various iodine species which imparted anti-bacterial properties.

The anionic agent containing dichloro-s-triazinyl reactive group was synthesized and applied to the cotton fabrics to introduce covalent bonds. This attempt was expected to improve the affinities of cationic compounds, such as cationic dyes, chitosan, quaternary ammonium antimicrobial agents and metal ions, by the electrostatic attractive force. As expected, the anionic agent was reacted with cotton fabrics at room temperature. In order to examine the adsorptivity of the cationic compounds on to the anionized cotton fabrics, firstly a cationic dye(C. I. Basic Violet 7) was applied. The color strength of the dyeing of anioized cotton fabric was highly increased comparing to that of untreated fabric.

We prepared natural indigo/calcium hydroxide complex powder from tinctoria's leaf, according to the demand of developing new dyeing technique of natural fibre with natural indigo. FT- IR and UV/Visible spectra were operated to find the dyeing properties of synthetic indigo and natural indigo powder. Cotton, flax and silk fabrics were dyed with different pH, dye concentration and dyeing time. The colour yield of indigo dye was quite sensitive to dye bath pH and fabric. In synthetic indigo, the highest K/S value of dyed silk fabric was shown at near pH 9.0, and which of flax and cotton fabric were shown at pH 11.0. In other hand, in the case of natural indigo complex powder, the highest K/S value of dyed silk fabric was shown at near pH 8.0, and which of flax and cotton fabric were shown at pH 9.5∼pH 10. Mercerized cotton fabric dyed with natural indigo powder has a little antimicrobial activity.

This study investigated the proper dyeing conditions, fastness and functionality of cotton fabrics dyed with Perilla frutescens var. acuta extract. Repeat dyeing, combination dyeing of persimmon juice and fermentation dyeing were conducted as dyeing conditions. It was confirmed that the ΔE and the K/S value of cotton fabrics dyed with Perilla frutescens var. acuta extracts depending on repeat dyeing and combination dyeing slightly increased. Furthermore, the fastness to washing of persimmon combination dyeing and fermentation dyeing was very good. The fastness to rubbing was shown to be above grade 4 in all methods, and the fastness to light was not as good as grade 3 or lower. The persimmon juice dyeing, Perilla frutescens var. acuta extract repeat dyeing 4 times and combination fermentation dyeing showed very good antimicrobial abilities. Thereafter, additional studies are needed to improve the fastness to light and alternatives to further improve the dyeing properties.

The textile industry has benefited from nanotechnology in various fields of application as the use of nanomaterials, and nanotechnology is multiplying. Nanoparticles can increase the performance of textiles by up to 100 times when used in finishing, coating, and dyeing techniques, providing them with capabilities they did not previously possess. Nanotechnology is used in the textile chemical industry to produce sports mats with stain resistance, flame resistance, wrinkle resistance, moisture management, antimicrobial quality, and UV protection. The incorporation of nanomaterials into fabrics can have a significant effect on their properties, including shrinkage, strength, electrical conductivity, and flammability. Various inventions and innovations may result from nano-processed textiles in the future, thus leading to the advancement of science. This article presents the construction of sports engineering structures with high resistance to improve the quality of sports training. The mechanical properties of sports mats are improved with the help of nanotechnology. Strength, elasticity, and tear resistance are among these properties. This method enables the production of elastic, durable, and tear-resistant sports mats.

Meta-aramid and polyamic acid were separated and the manufactured films were analyzed for their integration and logarithmic properties. The miscibility of meta-aramid and polyamic acid was analyzed by Fourier transform infrared spectroscopy and scanning electron microscopy. Using calorimetric analysis and differential scanning calorimetry, the storage of meta-aramid and polyamic acid, indicated on the right side of the column, was analyzed. It was confirmed that the initial thermal resistance occurs because the polyamic acid is accounted for in the meta-aramid, and the glass transition temperature and persistence phenomenon are explained.

The aim of study was to elucidate dyeability and antimicrobial and antifungal activity of silk fabrics dyed with Sophora Radix extracts according to different mordants. Dyes were extracted from Sophora Radix using ethanol. Then, silk fabrics were dyed with extracts two times by post-mordanting method in which the extract was 60%(owf), the mordant was 3%(owf), L.R was 1:20, the temperature was $60~60^\circ{C}$, the time of dyeing was 60min., and the time of mordanting was 60min. The dyeability was evaluated by surface color, K/S values and durability of dye. The skin microorganisms used in this study was S. sureus, B. subtilis, S. epidermidis, P. acnes, P. aeruginosa, E coli, A. niger, C. albicans and T. mentatrophytes. The results are as follows; 1. When mordants were added, K/S value of silk dyed was not improved much and surface color was 2.2Y to 8.8Y in H(hue) value which indicated greenish yellow to raddish yellow 2. The color fastness tests to light, perspiration, dry-cleaning, rubbing, and stain fabric washing show 4~5th degree which were valuated excellent. The color fastness to fade washing was improved to 3~4th degree by addition of $K_2CrO_7$ mordants. 3. Antibacterial activity of silk dyed using no-mordant as well as mordants was excellent on S. aureus, B. subtilis, S.epidermidis and P.acnes, but showed poor antibacterial activities on P.aeruginosa and E.coli such as gram negative baterials 4. Antifungal activity of silk dyed with ethanol extracts was good on A.niger, C.candida and T.mentagrophytes. Especially, on T. mentagrophytes there was no growth of fungus during 72 gous in silk dyed mordanting with $SnCl_2\cdot{2H}_2O$.

In this study, eco-friendly functional leather was developed by recycling wastes such as eel skin, marigold(Tagetas erecta l.), hinoki cypress(Chamaecyparis obtusa). The hot water extracts of marigold and hinoki cypress leaves were freeze-dried at $-80^{\circ}C$ to prepare colorant powder. The dyeing of eel leather with marigold was carried out to investigate the effects of dyeing conditions, mordanting on dye uptake, color, morphological change, and color fastness. Considering shrinkage of eel leather caused by dyeing, the optimum dyeing conditions were $60^{\circ}C$ of dyeing temperature and 60 min of dyeing time at 1:100 of bath ratio, and color of the dyed eel leather was Y to YR Munsell series. In order to prevent the degradation of leather from microbe, we conducted combination dyeing with marigold and hinoki cypress leave colorants. In this case, the combination dyed eel leathers showed excellent antimicrobial activity with above 99% bacterial reduction rate against S. aurieus and K. pneumoniae. It was confirmed that all of the dyed eel leathers were sufficient to meet the Korean Standard for color fastness of leather products. It can be applied practically for the development of eco-friendly functional leather by utilizing some useful active components extracted from plant resources and by recycling food wastes.
