The domestic textile industry is currently making an active effort to present high value-added materials that can respond immediately to the wants and needs of consumers sensitive to the of originality of design and emotionally appealing fashion materials. This paper attempted to present the creative development of materials in the contemporary clothing culture in which consumers' needs are individualized and differentiated and the cycle of life in fashion materials is getting shorter. To be specific, the paper presented the texture of peculiar expression to diverse cotton materials using the Woolsmok technique in the processing of felt. The chosen Merino wool was felted to 8 kinds of cotton with different density and structure. The touch, texture, visibility and complex susceptibilities of new materials were presented as different materials of cotton and wool were transformed into one material. In felting cotton fiber through wool, the transformation of diverse textures was presented and compared in the method using the washing machine in an attempt to enhance the efficiency of the traditional craft technique and work. This study proposed the possibility of placing the new material made up of cotton and wool beyond the range of functionality of each simple material, activating it as the peculiar material and expanding it to the range of its use as fashion material in the clothing industry. It is expected that this material will become competitive material at home and abroad by being activated as the clothing material of artistry, workability and marketability that can satisfy the tastes of consumers who call for high quality and diversification.
This study examines the dyeability of fabrics in relation to dyeing temperature, time, concentration, and the number of repeated dyeings. For this study, at first we extracted natural dyes from the peel of C.umshiu mandarin, which is fast as a dye and considered as recycling agricultural wastes. Additionally, it represents the image of Jeju Island. Then, we dyed cotton, wool, silk and nylon fabrics with the extracted dyes. The findings of this study are as follows. 1) Dyed cotton, wool, silk and nylon fabrics with the extract of C.umshiu mandarin peel are generally yellow. 2) Wool, nylon, silk, and cotton, in this order, are of good dyeability; Wool fabrics have the highest dyeability and cotton fabrics have the lowest. The dyeabilty of cotton fabrics was not improved even after dyeing in different conditions. 3) Colorfastness with washing, rubbing and perspiration are all good, while colorfastness with light is poor. 4) Higher dyeing concentration makes better dyeability. 5) Dyeability is enhanced as the dyeing temperature increases, while the dyeability of silk and nylon is relatively good even at low temperatures. 6) Looking at dyeability according to dyeing time, the longer the dyeing time, the better the dyeablility. Sixty minutes of dyeing time is appropriate to dye fabrics. 7) With an increase in the number of repeated dyeings, increased dyeability is obtaihed.

Dyeability of Indian natural dyestuffs to fabrics was investigated. Indian dyestuffs are more inexpensive than domestic dyestuffs purchased at oriental medicine stores. We studied the dyeability of madder, marigold, and pomegranate imported from India on cotton, silk, and wool fabrics. Dyebaths of a combination ratio of 80:20, 60:40, 50:50, 40:60 and 20:80 of madder and marigold, fabrics with orange colors were dyed. To evaluate the dyeability of dyed fabrics, K/S values, Munsell color values and CIE L, a, b, ${\Delta}E$ were measured. The dyeability of fabrics dyed in dyebaths of pH 4 and pH 7 were higher than pH 10. The dyeability in pH 4 was better than pH 7. Silk fabrics dyed with madder and marigold showed good dyeability and wool fabrics showed good affinity in madder dyebath and fair affinity in marigold dyebath. Cotton fabrics showed fair affinity in a marigold dyebath of pH 4 and pH 7. Cotton fabrics dyed with a 60:40 ratio of madder and marigold showed 4.76YR of Munsell color value. Silk Fabrics dyed with a 40:60 ratio showed 4.76YR and wool fabrics dyed with 20:80 ratio showed 5.57RY. The ratios produced the closest colors to 5.0YR of orange. This result indicated that marigold had a more powerful effect on cotton fabrics while madder was stronger on wool fabrics. Fading grades of washing colorfastness of wool and silk fabrics dyed in mixed dyebaths were higher than 3.5-4.0 and higher than homogeneous dyebaths. Staining grades of washing colorfastness of all dyed fabrics were between grades 3.5-5.0. Colorfastness to dry-cleaning was high as grades 4.0-5.0 in all of dyed fabrics. Colorfastness to light of dyed fabrics showed a fair grade of 3.5-5.0; in addition, wool fabrics showed lower grades than silk and cotton fabrics.
The purpose of this study is to understand the dyeing properties and color analysis of fabrics knitted with ramie, cotton, wool and acrylic by using scoria and to analyze whether the knitted fabrics can be used for industrialization by measuring color fastness after and before sliver-nano process. The following is the conclusions. Firstly, when ramie fabric regarding cotton, wool and acrylic was dyed at the temperature of $50^{\circ}C$ for fifteen minutes by using 10, 25, 50, 100g/ $\ell$ of scoria, dyeing absorption gradually increased up to 50g/ $\ell$, and over the point of 50g/ $\ell$ it showed slow increase. Secondly, regarding saturation, among ramie fabric, wool, cotton and acrylic, wool appears as the lowest brightness. Therefore, it can be dyed with bright color and the highest value. In terms of the value of chromaticity, wool also emerges as the lowest brightness. On the contrary, acrylic showed the lightest red as it had the value of the smallest b. Cotton takes the lightest yellow as the b value of the cotton showed the smallest. Thus, scoria dyestuff is a material that showed strong red and yellow on knitted fabric mixed with wool that is the biggest a. b value. Thirdly, in terms of dyeing fastness, sunlight fastness did not show noticeable differences before and after silver-nano processes, but in terms of washing and friction fastness, the material processed by silver-nano indicated that all knitted fabrics are over 4-5 point. which means silver-nano process can be effective for the industrial applications. As mentioned above, as a result of dyeing knitted fabrics with scoria, this study found a possibility of dyeing in the fabric materials, and if there is deeper dyeing experiments, fastness experiments and speculations, it might be possible to be a big issue just like loess and charcoal.

The purpose of this study was to evaluate the effect of chacteristics of knit fabrics on the microclimate of the skin simulating system. To determine the effect of characteristics of knit fabrics, vapor state of sweat pulse was simulated in the closed system. Different contents of fibers such as cotton, wool and polyester with different yarn size and knit types were chosen for specimens. The changes of humidity and temperature of air layer in the simulated systems were measured. Buffering indices, $K_d$ and $\beta_r$, were determined by considering $\alpha_p, \DeltaP_{max}, t_{max}, and tan\beta$. Physical properties of knit fabrics such as thickness, porosity, air resistance and moisture vapor transport were measured. Results showed that vapor pressure of wool was lower than cotton or polyester This was attributed to the hydrophilicity of wool which absorbed moisture rather quickly and retained in the knit fabric. The time to decrease vapor pressure was faster for polyester than cotton or wool. As a result, $K_d$ was in the order of wool> polye, item> cotton. $\beta_r$ of wool was rower than cotton or polyester due to its lowers porosity and slower desorption rate. For the yarn size, $K_d$ was in the order of 80's> 60's> 30's; thinner and lighter yarn showed better water vapor transport property. For knit type, buffering capacity of single jersey was better than interlock knit fabric. Statistical analysis showed that the air permeability was the most influential factor far the water vapor transport properties.

The cotton, wool, cotton/wool blended(80:20) and tencel fabrics were treated with low temperature oxygen or argon plasma, enzymes(cellulase or protease), or oxygen plasma-enzyme and examined for their weight loss and conditions for treatment for the environment friendly finishing. In the plasma treatment argon gas had better effect on the weight loss than oxygen gas did and the weight loss of all the fabrics was increased as increasing discharge power and discharge time. The weight loss of cotton, wool, cotton/wool blended(80:20) fabrics decreased in a large measure after 1 hr but that of tencel didn't decrease after 1 hr. In case of cellulose fibers oxygen gas plasma induced chemical functional groups on the surface of substrate more than argon gas plasma did so the weight loss of wool was larger than that of cotton, tencel fabrics in oxygen plasma-enzyme treatment. The weight loss of cotton and tencel fabrics decreased the initial stage because oxygen plasma pre-treatment caused cross linking as well as etching effect but argon plasma pre-treatment didn't. The plasma pre-treatment cleared the way for enzyme treatment on the whole but oxygen plasma pre-treatment bear in hand the increase of weight loss more or less because of the cross linking on the surface of cellulose fibers. The appropriate conditions for plasma treatment was 10-1Torr, 40W for 30minutes and for cellulase treatment were enzyme concentration of $3g/{\ell}$, pH 5, $60^{\circ}C$ for 1hr and for protease treatment were enzyme concentration of $4g/{\ell}$ pH 8, $60^{\circ}C$ for 1hr.
Studied on the changes of physical properties according to frequency of washing of sample such as cotton, ramie, wool, cotton knit, T/C. The results are as follows :1. The tensile strength in cotton, wool, and T/C was not changed by 5 times washing but in cotten knit was increased because hang-down phenomenon. 2.The crease resistance of cellulose fiber was decreased by repeated washing. In the case of wool, That was decreased considerably because of decreasing of elasticity and increasing of density caused by shrinking after washing. 3.The abrasion strength of wool was increased with increase in frequency of washing because of thickness caused by shrinking. 4.By repeated washing, the pills was generated in all of the samples and quantity of pills was increased with increase in frequency of washing, the pills was generated in all of the samples and quantity of pills was increased with increased in frequency of washing. Specially, in the case of cotton knit and wool, the pilling was remarkable. 5.The physical properties of dry cleaned wool was superior than that of wet cleaned wool.

To improve the deodorizing and antibacterial performance of various fabrics (cotton, silk and wool) dyed with pomegranate(Punica granatum L.) extract without mordants, natural colorant solutions, which were extracted from pomegranate using water as an extractant at $90^{\circ}C$ for 90 min with a various liquor ratio (solid natural colorant material/solvent water, weight ratio) from 1:100 to 1:5 were used. To achieve the highest K/S and the deodorizing and antibacterial performance, the best liquor ratio, dyeing bath ratio, dyeing temperature and dyeing time were found to be 1:10, 1:50, $80^{\circ}C$ and 60 min, respectively. The deodorizing performance of dyed cotton, silk and wool fabrics against acetic acid vapor were found to be95,70,90%,respectively. However, all the dyed fabrics displayed outstanding deodorizing performance(99%) against ammonia gas and antibacterial performance(bacteriostatic reduction rate:99.9%) against Staphylococcu aureus and Klebsiella pneumonia(bacteriostatic reduction rate: 99.9%). It is worth noting that pomegranate (Punica granatum L.) colorants notably enhanced the deodorizing and antibacterial performance of cotton, silk and wool fabrics.

The warmth retaining ratio of each material preyed to be high in order down> polyester> cotton/polyester>cotton>silk>wool fiber. 2. The warmth retaining ratio of each filling material decreased with the inclose of the humidity The effective reduction rate by filling fiber's was high in order wool>cotton>cotton/polyester>silk>down>polyester material. 3. The warmth retaining ratio of each filling material was shown to be in counter-correlation with the humidity, and the correlation coefficient (r=0.94-0.98) proved to be highly signi-ficant.
The acquistion and dyeability of the Gardenia jasminoides were examined to establish the optimum condition for extraction and storage in the process of obtaining the natural dye, Gardenia jasminoides colorant. Also the dyeability and colorfastness of Gardenia jasminoides were investigated. The results of this study are as follows. The optimum part-removed seed. In all experiments, the part of fat-removed seed and pericarp was used. The optimum condition for extraction of Gardenia jasminoides colorant was at 40℃ and for 90 min. in methanol. As storage temperature was higher, the absorbance of colorant extract decreased rapidly. The Gardenia jasminoides colorant exhibited dyeability to cotton, silk, wool, and nylon. The dyeability was the greatest in wool, and then nylon, silk, and cotton. Both wool and nylon had the greatest K/S value at pH3, however, nylon and cotton at pH 6 and pH 8 respectively. In addition, the increase in K/S value corresponded to temperature in wool and nylon, but the silk and cotton had the greatest K/S value at 60℃. Also, the K/S value increased in concomitant with the increased number of dyeing repetition. In the most cases, colorfastness of light was weak but colorfastness of laundry, sweat was relatively excellent.
