  • 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.

  • This paper describes the first part of a study for obtaining useful data on the development of compression garments with high stretch knitted materials. Twenty types of compression garments sold in the domestic market were analyzed in terms of the knitting method and knit structure. After classifying these garment types into three elements of knit structure, a comparative analysis of the body part to which knit structure is applied was performed. Given the superior comfort of its finished product and seamless process productivity, the weft knitting technique was used more commonly than the warp knitting technique. All extracted knit structures were single-faced, and float and tuck were variously applied based on plain stitch. Plain stitch was applied on smooth body part surfaces, which do not require much compression. In the case of body parts that easily accumulate mass, such as the lower abdomen and sides, plain with float stitch was used by employing a mock rib structure to exert appropriate pressure on body and ensure a good fit. However, on body parts requiring a strong fit and pressure along with protection, plain with float stitch was used. Meanwhile, the structure in which float and tuck were combined based on plain stitch was applied for body parts with active muscles.

  • This study analyzed the effects of the knit stitch type, fiber composition, and yarn thickness on the mechanical properties of knitted fabric. The results were as follows: The course density was the highest in the case of the rib stitch. On the other hand, the wale density was the highest in the case of the float stitch. The thickness was the highest in the case of the rib stitch. The same results were obtained even for different fiber compositions and yarn thicknesses considered in this study. The burst strength of wool knit fabric was higher than that of A/W knit fabric. The stiffness was the lowest in the case of the plain stitch. The same results were obtained even for different fiber compositions and yarn thicknesses. The pilling properties were excellent for all knit stitches, fiber composition, and yarn thicknesses as pilling degree : 5. The air permeability decreased in the following order : rib > plain > float stitch. The same results were obtained even for different fiber compositions and yarn thicknesses. The heat retention rate decreased in the following order : rib > float > plain stitch. The same results were obtained even for different fiber compositions and yarn thicknesses.

  • The mechanical and impact properties of the stitched Spectra composite was studied. The Spectra fiber reinforced vinylester composites were stitched with plain stitch to improve mechanical and impact resistant properties. The Spectra liber was used as a stitching thread and the composites were stitched twice in alternating sequence with plain stitch. The stitched composite showed different behavior with stitch densities in tensile and flexural properties. The effect of stitching has been changed with the mechanical properties measured under different restrained condition. The stitching has improved the preserving properties of the woven laminate composite structure by restricting the damage propagation.

  • The purpose of this thesis, therefore, is to examine the shaping methods and the knitting drafts of sleeve cap in the knitwears which are currently used by the manufacturers; to study the curve forms of sleeves in knitwears by analyzing synthetically the results of investigating the problems of knit wear sleeves; to present the most suitable sleeve cap for the knitwears. As the studying methods, I collected the basic data from the working-level persons of knit wear manufacturers, examined the knitting draft in the knitwears, and from that, made three kinds of comparative experimental garments and one kind of research experimental one as 10G and 16G. In doing so, I showed the sleeve cap suitable for the knitwears with plain stitch after operating sensual evaluation with Liker's 5-point rating measure. The analysis of data was handled with statistics by using SPSS Ver. 12.0; the method of statistics was executed by Frequency Analysis, Trust Analysis, one-way ANOVA, and Duncan test according to each topic of the research. As the result of the sensual evaluation of the experimental garments produced from the study, the research experimental garment looks better than the comparative experimental one in both 10G and l6G; has less extra folds around the front part of sleeve cap; looks more natural in sleeve caps of the body part and of a sleeve. From this, I am able to figure out that the research experimental garment looks better than the comparative experimental one produced by knit wear manufacturers. In addition, I can come to know that the different knitting of the front line and the back one of armhole in the knitwears has a favorable impact on improving the appearance of a sleeve.

  • The purpose of this study is to investigate change of mechanical and physical properties, shape behavior and hand value in weft knit when rib stitch and milan stitch are combined. The knit stitches used in this study are plain stitch, half milan rib stitch, milan rib stitch, $2{\times}1$ rib stitch, $2{\times}1$ half milan rib stitch and $2{\times}1$ milan rib stitch. We analyzed physical and mechanical properties(tensile, bending, shear, compression, surface properties, thickness and weight) of the knit stitches and calculated their primary hand value and total hand value through translational formulas using the KES(Kawabata Evaluation System). The results are as follows; In evaluation of mechanical properties and hand values of knit stitches, plain stitch had the highest flexibility and the lowest T.H.V. as women's winter knit wear. Since $2{\times}1$ rib stitch had too high elongation in one direction, although it had the highest T.H.V, it needs to be careful when plain stitch and $2{\times}1$ rib stitch are applied for women's winter knit wear. Since Milan rib stitch and $2{\times}1$ milan rib stitch had high T.H.V. similarly, it is considered that they are suitable for women's winter knit wear. Specially, when Milan stitch is combined with $2{\times}1$ rib stitch, its shape stability and fullness are contained and flexibility is added on it. Therefore, $2{\times}1$ milan rib stitch can be also applied for women's winter knit wear.

  • The purpose of this study is to analyze and document special design elements of the knit material, such as yarn, stitch, and gauge used in various types of knit in a collection of men's fashion, and to provide basic data for database design. The analysis covers 37 brand collections of men's clothing, used to collect a total of 1,954 men's knitwear photographs, and others were collected from 12 collections from F/W to 2017 S/S collection through www.vogue.com. The results of the analysis of the knit design elements of the contemporary men's collection since 2011 are as follows. First, there were 1,513 straight yarn (77%) and 440 decorative yarn (23%) types of yarn. There were many different kinds of decorative yarn, such as two tone and melange effect in three colors, and the emergence of hairy yarn, like mohair and angora shannell, which was much common in low gauge's knitwear designs. Second, the frequency was high with low and middle gauges. thin and light high-gauges were often found in S/S collections, but there were also thick types of yarn in low-gauge knitwear. Third, 794 (40.6%) items used basic stitches such as plain stitch, which was the most utilized. The plain stitch, which is the most basic of the knit stitches, appears to be in high demand for its use, along with the use of various decorators. The development of printing and dyeing technologies has led to many designs that utilize the printer for the plain stitch. 326 (16.7 %), of colored jacard stitch, and of 175 (0.9 %) of intasia stitch.

  • The nylofl P.T.Y. (producer textured yarn) stockings are knitted in plain stitch using a commercial seamless stocking machine. The rpm of this machine cylinder is changed in the range of 250, 450, 650, 850, 1050, and the mechanical properties of the fabrics which are produce at these rpm levels are analyzed. The experimental results using this machine show that the number of stitches per unit area, elongation, elastic recovery, resistance coefficient of elongation, and air resistance of the fabric are reduced as the rpm of the machine increased.

  • This study aims to find out the K values of 1 x 1 and 2 x 2 laying-in knit fabrics of plain stitch in fully relaxed state. The results are; 1. Both in 1 x 1 and 2 x 2 laying-in plain knit fabrics, knitted with the larger periphery of a feed, the thinner in thickness, the more air-permeability and the more elastic to be recovered from elongation was obtained. 2. Repeating of 24 hrs wetting at 40$^{\circ}C$ twice and drying in air at 70$^{\circ}C$ for 1 hr gives the fully relaxed state to the fabrics. 3. A tendency to decrease of K$_1$values with increasing SCSL was recognized and the K$_1$values obtained in fully relaxed state were 86-91, 167-174 for 1 x 1 and 2 x 2 laying-in knit fabrics each respectively. 4. The stable dimensions of laying-in knit fabrics are predictable with K values.

  • This is a study on the application of cylindrical shell buckling to weft plain stitch-knit fabrics made of cotton ems, which are related to bending deformations affecting textile products, especially hands and wrinkles of shell type apparel. Following conclusions were derived from the studies of cylindrical shell buckling under axial compressions and from the considerations of applicability of buckling theories to typical orthotropic knit fabric supposing as thin homogenous isotropic shell. 1. An apparatus for preparing and clamping specimens, and experimental methods were designed to be possible to measure cylindrical shell buckling properties under the action of uniform axial compression with a general strength tester. 2. Comparing the tendencies of critical buckling stresses to the various yarn numbers and cover factors of weft knit fabrics with the theoretical critical buckling stresses, the absolute values were found to be about 60℃ of theoretical values. 3. Bending stiffnesses calculated with the young's modulus obtained from buckling experiments were found to be fitted approximately with the results form pure bending tester.
