  • In this paper, silver slit yarns combined with cotton yarns were used to produce weft knits. The purpose of this study was to investigate the physical properties as well as the functional properties of weft knit with silver slit yarns. The six different weft knit fabrics were made from silver slit yarns varying knit structure and fabric density. One cotton weft knit was also knitted to compare the properties. Weft knits made from silver slit yarns were characterized by excellent antibacterial properties, electric magnetic shielding properties, UV-cut properties, anti-static properties, and air permeability. Although there were significant differences in the physical properties of different knit structure and the fabric density, weft knits with silver slit yarns were seen to have better end use properties and ideal for apparel than the cotton weft knits.

  • The colorfastness of dying persipiration and laundry on summer clothing must be considered, because it has special relation to the human body. The colors of fibers as cotton, p/c, acryl, polyester and nylon which have been widely used for blouse and T-Shirt of Knitted wear are R-P, Y-G, BI-B and print. Studies were carried out with persipirometer, for the natural fiber of cotton the chemical one of nylon, with additional stuff involved, which polluted. The experiment was conducted to colorfastness with acid solution and alkaline solution to see the alteration of color and staining of man-made persiperation. The results obtained from this experiment can be summerized as follows. 1. The order of color alteration isnylon < p/c < coton < polyester < acryl, and the nylon shows the lowest colorfastness, which is 3 class, and the acrly shows the highest colorfateness, which is 5 class. The staining of multifiber test of cotton fabric is nylon < p/c < polyester < cotton < acryl. The staining of multifiber of nylon fabric is nylon polyester < p/c < cotton < acryl. 2. In acid solution and alkaline solution, the alteration of color and staining makes almost no difference, but concerning staining of cotton, the acid solution is lower than the case of alteration solution only. 3. In the pollution on cotton and nylon, the latter is more easily polluted than the former regardless of fabrics. Especially in case of polluted nylon, ti shows the lowest color fastness (2 class), which causes a problem of the dying process and dye stuffs. 4. No difference of color alteration shows among them, but R-P and print show low color fastness (2 class), especially printed nylon shows the lowest value (1 class).

  • This paper focuses on the application of a novel mathematical limit approach derived for K/S values in reactive dyeing of cotton fabrics. The relation obtained from Kubelka-Munk equation is used because the Kubelka-Munk equation is the basic relationship among fabric reflectance, fabric dye content and dyestuff characteristics. The limit approach derived in a former paper is applied to the laboratory dyeings and the dyeing behavior of some reactive dyes on cotton knitted fabric has been obtained. The results of the laboratory experiments are discussed using the new mathematical approach. When the actual K/S values obtained from the dyeings and the calculated K/S values derived by the limit approach are considered independently, it is observed that the limit relation is val id for low dye concentration applications. When the K/S values are calculated taking the K/S value of the initial dyeing concentration $(0.1\;\%\;owf)$ as the starting concentration by applying the result of the derived limit approach, the calculated K/S values fit with the ones obtained in actual dyeings. It is concluded that the novel approach presented in the paper can be used in calculating the K/S values when the initial dyeings at low dye concentrations are carefully carried out.

  • The purpose of this study is to develop knitwear design expressed not also Green but also LOHAS using natural yarns(wool and cotton) dyed with various natural sources(sappanwood, indigo plant, turmeric, cochineal, coffee, gallnut, and persimmon juice). This researcher tried to suggest solution scheme through the development of knitwear designs to break from the cottage industry and the limitation of design in Jeju and to preserve of traditional dye with persimmon juice simultaneously. Knitting is the formation of a fabric by the interlooping of one or more sets of yarns with hand knitting or industrial knitting. In hand-knitting, the two fundamental stitches are described as knit depending on the direction of the loop formation, front to back or back to front. In machine-knitting, the direction of loop formation is fixed, unless the stitch is mechanically transferred from front to back needle bed or vice versa. Industrial knitting technology can be divided into two main areas - weft knitting and warp knitting. Each has a different principle of construction. The majority of knitted fabrics for clothing are weft-knitted, and so this study is used weft-knitting and hand knitting technology. To achieve this purpose, researcher tried to present a lot of knitwear designs using yarns dyed with various natural sources focusing on Modern & Sophisticated Image and Elegance & Romantic Image to satisfy adult and missy consumer needs.

  • The purpose of this study was to investigate the fitness using the draft method to develop moderate-stretch knit block pattern for young women in Korea. The subjects were three women within the range of the ages from 18 to 24 showing the average body figures. In this study, 4 different patterns were drafted for the moderate stretch knitted fabrics, that were categorised into two different types. The first type of these was made up for kilted fabrics and the other was initially drafted for woven fabrics and altered for knitted materials afterward. The major findings derived from this investigation were as follows; 1. According to each sensory evaluation for the appearance test on fitness, knit block patterns A and D were the better than the rest of them. 2. Knit block patterns A and D with higher evaluation scores were drafted with body size measurements except the waist line, whereas patterns B and C with relatively lower scores were produced including the smaller ease amounts than the woven block pattern. 3. To see the results of the functional test based on the designed ten motions for this experiment, knit block patterns A and B were concluded as better than the rest of them. In addition, concerning the arm liking motions, pattern B was scored as the best among the developed patterns.

  • The purpose of this study was to examine the effect of covering yarn's twist on mechanical properties of knitted fabrics of composite yarns with single covering process. Four yarns that were used in this study: two different composite yarns made from the four kinds of cotton and functional polyester-(Poly-A) with the ratio of 52:48, and the rest two yarns are the original cotton 100% yarn and the poly-A 100% yarn. The two kinds of composite yarns, CP1 and CP2, were processed on the single covering process. CP1 was applied on the single covering process with S-800 tpm, where Poly-A was used as covering yarn and cotton was used as core yarn. CP2 was applied on the same process as CP1 except that Poly-A had been applied on the two-for-one twisting process with S-400 tpm on the previous step. Sixteen mechanical properties of all the four knifed fabrics knitted under the same knitting conditions were measured by KES-FB system with the outer knit condition. And 3D CAD dressmaking simulations, which were driven by some of the mechanical properties, were presented. The results were as follows: CP2 had high RT values with twisting of covering yarn. CP2 also had high B, 2HB values because of higher linear density. SMD was affected rather by twisting of covering yarn than by fine hair of the cotton surface. Twisting of covering yarn made it decreasing T value and increasing W value. Dressmaking 3D CAD simulations showed that there are buckling effects on CP2 because of high bending rigidity and shear rigidity.
