  • This research investigated the mechanical properties of the 4 different types of $3{\times}3$ cable stitches on weft knitted fabrics. The 4 kinds of cable-stitch fabrics were knitted under the same knitting conditions, then the mechanical properties, such as tensile strength, elongation, stiffness, etc. were measured according to the Korean Industrial Standards (KS K 0642). The knitting time for the sample produced by the knitting process 1 was the shortest among the 4 different types of samples. It means that the knitting process 1 would have benefits of higher productivity if there is no yarn breakage during the knitting of the cable stitches. In the test for tensile strength, the samples produced by knitting processes 3 and 4 have tensile values of approximately 8~11% higher than the sample produced by knitting process 1. The test for elongation also shows that the samples produced by knitting processes 3 and 4 have up to 18% higher elongation values than the sample produced by knitting process 1. On the other hand, the stiffness test showed no significant difference between the 4 samples. This study is expected to increase the competitiveness of the local knitting industry as a result of providing basic data on the mechanical properties of special knitted stitches, such as cable stitches.

  • 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.

  • Knit is classified into two such as basic texture and applied one according to knitting principle, and the basic texture of weft knitting consists of single knit. rib knit, purl knit and interlock knit. The basic texture of warp knitting consists of double knit texture, double code knit texture and double vandyke knit texture. Fourteen costumes were produced with eighteen (18) different types and twenty four (24) raw materials, and we were trying to show a wide range of costumes produced with knitting by making two different brands at random and making different designs depending on four seasons. Knitting technique is very important element in that it allows special surface effectiveness and decides the characteristic of knitting materials. Knit designer plays very important roles such as selection of raw thread, deciding knitting technique and type of knitting machine in designing the knit. Therefore, the knit designer requires the ability to utilize the function of knitting machine to the maximum, the effort to acquire the variety of knitting technique, develop the new knitting technique and for the improvement of knitting design.

  • The purpose of this study was to analyze and minimize structural error between sample knitting and actual knitting in weft knitting apparel. Basic stitches used in this study were plain stitch, $0{\times}0$ rib stitch, $1{\times}1$ rib stitch, $2{\times}2$ rib stitch, Milan rib stitch. They were knitted into two different gauges(7 and 12 gauge) and 6 different sample sizes by computer program. The weight, length and width of these 5 basic knitting stitches were measured and their changes according to gauge, stitch and knitting were calculated and analyzed. The results were as follows; The weight of $0{\times}0$ rib stitch was the largest, followed by Milan rib stitch, $2{\times}2$ rib stitch, plain stitch and $1{\times}1$ rib stitch. As the density of stitch per unit area increases, the weight increases. The length of $0{\times}0$ rib stitch was the largest, followed by plain stitch, $2{\times}2$ rib stitch, $1{\times}1$ rib stitch and Milan stitch in both 7 and 12 gauge. As the number of course increases, the length increases accordingly. However, its increase ratio shows higher than that of number of course. It means that the reduction in number of course is needed to get aimed length. The width of Milan rib stitch was the largest, followed by $0{\times}0$ rib stitch, plain stitch, $2{\times}2$ rib stitch, $1{\times}1$ rib stitch in 7 gauge. In 12 gauge, Milan stitch, plain stitch and $0{\times}0$ rib stitch were the highest, followed by $2{\times}2$ rib stitch and $1{\times}1$ rib stitch. It showed that the change in shape of stitch influenced on the width more than the length of stitch.

  • The purpose of this study is to examine the type of stitch and designs of knitwears using handcraft ornament techniques. This paper will also go on to develop and merchandize high value generated by design development. Knit is largely divided into weft knit stitch and warp knit stitch which are respectively woven by weft knitting machine and warp knitting machine. For clothing, circular knit and flat knit are frequently used while plain stitch, rib stitch and purl stitch are perceived as the basic stitches. Denbigh stitch, cord stitch, atlas stitch, which belong to tricot stitch, are the basic of warp knit stitch. There are also numerous fancy fabrics adapting the previously mentioned stitches and these are made into solid pattern and yarn dyed pattern. The handcraft ornament techniques in knitwears design are embroidery, beads, sequin, stone, printing, applique and fringe, etc. By applying these techniques thus creative expression, which cannot be expressed in other fashion items, is feasible. The women's knitwears are tries by mixed and various techniques, develope to high value knitwears, escaping from simple and practical items.

  • Using conventional textile techniques such as weaving braiding knitting and stitching it is possible to produce a wide range two and three dimensional fiber preforms, however so far only a limited attention has been given to knitted fabrics in composite industry. This is mainly due to the opinion that knitted fabric reinforced composites posses low mechanical properties owing to their looped fiber architecture. But it is possible to obtain desired mechanical properties by selecting proper knitted fabric structure, In this paper mechanical characteristics of kevlar plain weft knitted fabrics reinforced plastics(KFRP) are evaluated for th development of intrusion beam of car side door. Tensile bending impact properties of KFRP are measured experimentally and crush demands of Americal Federal Motor Vehicle Safety Standard No.214(FMVSS 214) compared with the bending load and displacement of KFRP by quasi-static test method. The applicability and limitation of bending load and displacement of KFRP according to specimen size has been discussed.

  • Shrink-resist effects and properties of the knitted fabrics from wool/acrylic(W/A) fiber blends were determined to find out an optimal blending ratio keeping the quality properties of wool products. The test fabrics were knitted by a weft knitting machine with all needle knitting structure ($0{\times}0$ rib) under the same knitting conditions with five different types of yarns: $W100\%,\;A100\%$, and W/A blended yarns(70/30, 50/50, 30/70). Shrinkage during repeated washing, electrostatic propensity, thermal resistance and pilling propensity of W/A knits. The shrink resistance was significantly enhanced on repeated washing of W/A knits, especially, over $50\%$ acrylic blended knits. Addition of strong physical force and alkali detergent applied in this washing experiment brought about superior effects with the low shrinkage rate although it was very severe washing conditions for wool fabrics. The results from the washing experiment implies that W/A blend knits can be machine washed at individual households with other ordinary laundry. There was some changes and variation found in thermal resistance, electrostatic propensity, and pilling. W/A 50/50 blended knits did not bring serious changes to other physical properties comparing with original wool, which helps consumers care wool knitted clothes more conveniently.

  • The market demand for knitwear has been increased both domestically and in export. Despite of the high and consistent demand, knitwear design has been rather simple and tends to show mainly foreign influences. In order to compete efficiently in the world market and to provide more variety, knitwear design originated from our cultural background needs to be developed. Therefore, the purpose of this study is to develop various knitwear design adopting the Korean traditional 'Danchung' motifs and the main colors used in the motifs. Three knitwear works were designed and constructed, which included a round pullover, a half-sleeve V-neck one-piece dress, and an evening dress. The mainly used motifs consisted of natural motifs such as lotus, cloud, and motifs symbolizing good luck such as 壽 and 囍. The Original 'Dan-chung' motifs were stylized into different forms and colors, and this design work was done using CAD system including the 'Adobe Illustrator 9.0' and the '4D box Hi-Knit Program'. Based on the designed images created by the CAD system, an actual design works were knitted using different weft knit methods including a hand knitting machine and weft knit machine of the knitwear manufacturers. This study provided the possibility of knitwear design originated from the Korean traditional culture.
