The knitwear industry requires ways to satisfy a changing environment. This study suggests a knitwear design process using a knit CAD program. Such a process needs to implement a CAD system that develops a sufficient knit design system to advance the knitwear industry in both planning and manufacturing. In order to contextualize this research, this study reviewed the current state and problems of the knitwear industry and the market, and investigated the actual condition in which the CAD system is used in knit design by CAD system service providers. The findings of the study are as follows: First, All brands had individual ways to reduce the amount of lead-time. The knit designers pointed out that any given sample product is made in the form of a swatch; after the knitting step and prior to the manufacturing process. In women's wear brands, basting was inserted into the production process in order to reduce the amount of sample losses. Second, a CAD program enables the uses of swatches to see the adequacy of yams, textures, and style that simulate the completed style. Third, this study examined the efficiency of knit design process conducted by the knit design CAD system based on expert assessments, showing that the use of a knit CAD program in commercial knit design proved to be more efficient than in previous models.

The appearances and geometry structures of knitted fabrics have important effects on their functions as textile fabrics. Structural design of the woven fabric, prior to the manufacturing processes in the weaving mill, often leads to a similar predictable appearance in the final outcome with the corresponding weave design. The increase of the employment of elastic textile yarns in knitting fabrics for comfort stretch or outdoor sports wear knit products has, however, resulted in difficulties in predicting the final appearance of the knit structure design. Due to the stretchability and exceptional recovery behavior of the elastic yarns such as polyurethane elastomeric yarns, the appearance of the final product often differs from the initial knit design. At textile CAD program for preparing tricot knit designs has been employed in this study to predict the two dimensional appearance of the design. The similarities between the designs and corresponding knit products seem to be acceptable for the two-dimensional textile CAD program in this study. However, when elastomeric yarns are partially employed in the polyester filament tricot product, a considerable amount of departure from the design is apparent due to the constriction and/or deformation of property differences in the elastomeric yarns and polyester filament yarns. Therefore, another purpose of this study is to measure the departure of the final tricot product from the initial tricot design, especially in the case employing elastomeric yarns in the knit structure together with regular polyester filament yarns. For measuring the three-dimensional departure, a 3D scanning system has been used for the mesh reconstruction of the fabric specimen. Hopefully, the result from this study will be used as a guide to modify and improve the current textile CAD program proposed for the two-dimensional simulation of the tricot.

WKSF (Warp-knitted spacer fabrics) knitted using a double Raschel machine is the three-dimensional knit that has vertically connected separate layers in loop structures. Because of its unique structure, the fabric is light, compressible and breathable. Owing to the high production speed, the use of the fabric is increasing in various areas. The purpose of this study is to establish the design process in the utilization of WKSF program and analyze the difference between WKSF and Neoprene as garment materials.. The study on the design related to WKSF has rarely been carried out because of the complexity of WKSF structure and the difficulties encountered in analyzing the structure and thread. Therefore, checking beforehand the simulation results similar to a final knit using the CAD program for WKSF can only enhance the efficiency of the design for the light knits. The conclusion drawn after designing the light knits using the CAD program and analyzing the pros and cons of WKSF through the various property evaluation techniques is as follows. The tension characteristic analysis results indicated that Neoprene specimen has the elastic transformation and resilience, thus behaving like an elastic product such as rubber. By contrast, in the event that clothing and fashion accessories are designed with WKSF, these products are kept in a boxy style fit so that the fabric can be applied flexibly to a curvy body line. In addition, WKSF is good in forming noticeably around a curvy body, because its resistance shear deformation is lower than that of Neoprene.

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.

By introducing Mondrian's creative world into the field of fashion design, I examined how its application can satisfy not only visual expressions but also the desire of fashion design for its simplicity, individuality, and sensitivity. As a program developing designs and guiding how to produce, the textile CAD system helps to develop a variety of textile systems. In case of dying or textile printing, a variety of free expressions of print patterns and functional color simulations are possible by the configuration of colors or enlargement of design. It can also confirm the flexible simulation with a variety of color changes through the monitor by treating the knit design with dots. Especially in case of consulting for the design with ordering customers, the system is very speedy and effective, because it is possible to correct on the spot those complicated elements of designs and color sensation and see the prints in the light of marketing, processing and artistic value. Mondrian's Art, beauty of balance and proportion in the Mondrian's plastic forms, the changes of coloring and texture were added into vertical and horizontal lines and the divisions of faces for the dressmaking. Whether they were the reciprocal action of human body, texture and color or the reciprocal action of human body and colors, these changes will be interpreted differently, depending on the individuals' experiences and psychological moods of situations. The emphases of the sense are also different, depending on the activity and functionality.
