  • The defects occurred in knitted fabrics have several types due to some trouble sources. In particular, the defects caused by knitting machine troubles give a serious damage to the whole webs. It is, therefore, necessary to discriminate the kind of defects. The method to discriminate the type and size of defects has been proposed, which is used a pair of narrow band eliminating spatial filters. This method is based upon an isotropic signal processing in time domain. This paper is to confirm that the proposed method can be useful in the discrimination of defects, having analyzed in spatial frequency domain.

  • Recently, knitted materials are used more often than ever before in fashion. Therefore it is necessary to study their application into garment patterns. The purpose of this study was to develop a system by which the tensile property of knitted fabrics can be applied. In this study, 5 different distribution methods of tensile property were tested on 2 sample fabrics which have a lower and higher tensile property than moderate-stretch. The subjects were five women within an age range from 18 to 24 who showed average body figures. The major findings derived from this investigation were as follows; The 4th method was regarded as the most valid. The 4th method was fixed proportional alteration based on the reduction amount of bust girth, i.e. front (back) width and shoulder width reduced by 60% of the bust girth reduction and neck point reduced by 28% of the bust girth reduction. When the reduction was based on the proportion of the actual measurements, the alteration was too severe, so that the armhole curve was changed into a very uncomfortable curve.

  • This Study executed the newly developed warp knitted fabrics for the end of living textile materials and investigated the dyeing behavior with the change of drying temperature. There were also analysis of yarn properties in the process of dyeing and finishing. Above all, we examined the influence of touch and softness according to processes. So we can expect the optimum yarn and condition for the better textile goods.

  • 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.

  • This study was conducted to estimate the amounts of the electromagnetic wave penetrating from a cellular phone in a pocket of dress shirt, as well as to test how different the penetration amounts were under the conditions of wearing. It was also investigated the possibilities that the amounts of the electromagnetic wave penetrating could be decreased by using twofold pocket or electromagnetic wave free fabric. The amounts of the electromagnetic wave penetrating were measured in the following five cases; one-layered pocket with 10 different fabrics as dress shirt, a pocket adding a layer of knitted cotton, two-layered pocket with same fabric as dress shirt, two-layered pocket adding a layer of knitted cotton, and one-layered pocket adding a layer of electromagnetic wave free fabric. Each of these five cases were measured using the front and back sides of a cellular phone facing to the body. The results were as follows; 1) The amounts of the electromagnetic wave penetrating were not significantly different in 10 different fabrics and were all above the caution range (0.02mW/$cm^2$). 2) The amounts of the electromagnetic wave penetrating in cases of the back side of the cellular phone to the body, were more than in cases of the front side. 3) There is a significantly differences in part on adding a knitted under wear to one and two layers of the pocket in the case of penetration amount under the wearing conditions. 4) The amounts of the electromagnetic wave penetrating in cases of adding a layer of electromagnetic wave free fabric, were close to the safe standard value of it. The above results suggested that facing the front side of cellular phone to the body and using extra layering with some electromagnetic wave free fabrics might have some protective effects again to the penetration amounts.

  • The studies on shrinkage and characteristics of the weft knitted fabrics were investigated under the various dry and wet treating conditions. Various relaxation values were found out according to treating conditions. The characteristics of knitted fabrics such as shrinkage rate, thickness, spirality, elongation and recovery were also measured. The used knitting yams were OE (open-end) cotton and POY (pre-oriented yarn)-DTY (draw textured yam) polyester. The conclusions obtained in this study are as follows. 1. In case of dry relaxation little change of Ks values was seen with increasing time after 48 hours. So it was found that relaxation shrinkage of dry relaxation reached its maximal state in about 48 hours. 2. In case of wet relaxation, higher Ks values were observed, in comparision with those of dry one and higher shrinkage rates were also observed. But when experimental temperature was constant, sudden marked increases in Ks values and shrinkage rates appeared through the initial 4 hours, and after that time little change was seen in them. 3. As Ks value increases, thickness also increased. But thickness showed to some degree stability around Ks value 23. 4. As Ks value increases, spirality values also increased gradually. But little change of spirality values was observed above a certain Ks values (cotton 22.5, polyester 21.5). 5. As Ks value increases, the elongation decreased under a certain load, and the recovery was random.

  • Recently, consumer tastes of various classes at home and abroad prefer comfortable, unadorned, and simple clothing, and the athleisure trend, which can be used freely in daily life as well as exercise, has expanded to overall clothing products. Existing materials used for athleisure are composite knitted fabrics using polyester yarn and PU yarn, which has problems due to a chronic lack of color fastness and contamination by dyes even when PU laminating is applied, making it difficult to apply various colors. There is a quality problem in which deformation of the product occurs due to lack of durability. In this study, CDP yarn(75de/72f) and PU yarn(40de) were selected to commercialize the circular knitting for athleisure using CDP yarn in order to solve the problems that occur in the dyeing and laminating process when using polyester materials. CDP yarns were used to knit into single(CP75-S) and double(CP75-D) knit and single knit were found to be suitable as athleisure fabrics. After pretreatment and treatment under various conditions, the stainability of CDP circular knitting was examined. After pretreatment and dyeing process under various conditions, the property of scouring and dyeability of CP75-S were evaluated.
