The purpose of this study was to research the effect of sewing threads on sewability. The materials used in this study were cotton threads, p/c spun thread, polyester spun thread and core-spun thread, which were the same in count, but different in fibers. In order to approach the purpose of this study, the change of sew-ability was measured according to the number of laundering. The results from this measure were as follows; 1. The order of seam strength according to the sewing threads was polyester spun threads, p/c spun thread, core-spun thread, and cotton thread in proportion to the loop strength of the sewing threads. The preserving rate of strength after laundering was the highest in core spun thread. 2. The order of seam elongation according to the sewing threads was polyester spun thread, p/c spun thread, core-spun thread and cotton thread in proportion to the elongation of the sewing threads. The preserving rate of elongation after laundering was the highest in core spun thread. 3. The order of seam puckering according to the sewing threads' was core-spun thread, p/c spun thread, polyester spun thread and cotton thread. The order of changing rate after laundering was the same as the former order. 4. The order of the needle temperature according to the sewing threads was polyester spun thread, core-spun thread, p/c spun thread and cotton thread.

In sewing, fabrics is fed by an elliptic motion of the feed dog. The feeding control mechanism controls an elliptic motion of the feed dog, finally, controls stitch spacings and feeding directions of fabrics. This study discusses the feeding control mechanism of an industrial lock stitch sewing machine, which is a good example to study a machine kinematics. This study makes mathematical expressions of machine's motion in the feeding control mechanism. Thus, the motions of this mechanism are characterized, which will be used for kinematic analysis of the feed dog later. Also, the above mathematical expressions may be a basis for the new design of the feeding control mechanism and may be applied to development of the similar feeding control mechanism of other type sewing machine.

Generally, the required control functions for the industrial auto trimming sewing machines are the sewing speed control with pedal input, the up/down stopping-position control of the needle, the automatic sewing according to the memorized sewing pattern including the number of stitches, and etc. We developed a new type of AC servo motor controller, which suffices for all the above functions. The developped controller is working well, and the performances are very good for the practical use.

In this paper, we present a BLDC Motor control for needle positioning and velocity control in the industrial sewing machine. In the industrial sewing machine, the fast acceleration control is needed, especially for a person who has a skill in operation of sewing machine for more products. And it is also needed to have a less noise and vibration. But the system which is made in a low price has no feedback system for a current control. Therefore we propose the method of velocity pattern that has an acceleration of velocity and Anti-windup algorithm. By the experiment, we confirmed that these manner have a good performance for low noise, low vibration and fast acceleration in the industrial sewing machine.

This study suggests designs for fashion-cultural products that can communicate the uniqueness of Korean traditional culture. To this end, motives and printing patterns were created based on the formative beauty of traditional sewing crafts. A literature review was completed to identify characteristics of Korean traditional sewing, and the motives were developed through Adobe Illustrator CS4 and Adobe Photoshop CS4. Those motives were applied to handkerchiefs, neckties, pouches, and handbags. The sewing crafts used in this study included thimbles, bobbins, and chumoni (a Korean traditional pouch). The motives were produced in a manner that best exemplified the unique formative beauty of the sewing crafts while also presenting modern images of the crafts. The motives from thimbles reflected the lateral side of their originals, while the motives from bobbins adopted fan- or rectangular-shaped bobbins. The motives from chumoni were based on Duruchumoni and Guichumoni. A total of 12 motives were developed, and a total of 36 textile designs were suggested based on those motives. A total of 42 designs for fashion-cultural products, including handkerchiefs, neckties, pouches and handbags, were developed. Among them, motives applied to handkerchiefs were expanded to apply to scarfs, as well.

The heat setting of sewing thread is known to have some puckering. In this experiment, the P/C fabrec and polyester thread were heat setted at temperatures ranging from $70^{\circ}C$ to $150^{\circ}C$ at the interval of every $^20{\circ}C$ for the period of 1, 5, 10, 20 and 40 minutes resoectivly. The results obtained are as follows: 1) In general, the pre-laundering sewing shrinkage related negatively to time but related positively to temperature. And it showed the lowest rate at $110^{\circ}C$. 2) In case of slack treatment, the post-laundering sewing sewing shrinkage marked the lowest rate at $130^{\circ}C$ while that of stretch treatment showed the lowest rate at $90^{\circ}C$. 3) The rates of post-laundering sewing shrinkage were higher than those of pre-laundering shrinkage, the difference between them reached the bottom when applied the slack treatment at $130^{\circ}C$ and the streched treatment at $110^{\circ}C$.

Recent increase of eco-conscious trends and pleasure from Do It Yourself (DIY) activities have led to a surge in sales of package products bundling together clothing patterns and raw materials. However, a well-structured market system is yet to be established. We surveyed 460 women with sewing as a hobby who had purchased these DIY clothing pattern packages. The survey revealed that majority of respondents had their hobby for over five years. Choosing the right fabric to match clothing patterns presented a common challenge. Most participants owned a sewing machine and an overlocker, with price being the primary concern when purchasing a package. For guidance during the sewing process, participants preferred print materials featuring real-life images. Those with less sewing experience leaned towards video tutorials. Items of interest or those commonly created included blouses, shirts, and dresses. Desire for further learning in sewing and pattern-making was prominent, with a clear preference for online classes. Several strategies are recommended to enhance the appeal of DIY clothing package products, including broadening range of packages that incorporate fabric, offering supplementary educational resources to improve users' skills, implementing affordable pricing structures, supplying comprehensive creation guidelines, and making available design modification guides. These considerations could significantly boost customer satisfaction. This research intends to lay groundwork for understanding DIY clothing creation market, ultimately fostering production of highly desirable products. Insights of this study will prove instrumental in refining product development and devising effective marketing tactics, leading to a more rewarding consumer experience.

This comparative study analyzes and compares tight skirt sewing methods which are found in the clothing configuration reference text books available in contemporary universities and which are used in commercially-available domestic consumer products. The study samples included 15 text books and 12 tight skirt consumer products of different brands on sale at three department stores in Seoul each of which had a belt, a back-centered zipper, and back double slits. The findings of the study are summarized as follows: First, text books mainly show very basic sewing methods of using zippers on both sides of the straight-lined waist belt. This indicates that it is necessary for such methods to be complemented so that they cover a recent variety of designs, materials, and sewing machines. For consumer products, the main sewing method is to use a curved waist belt and a console zipper in silhouette running across half the hipbone. Second, consumer products employ three different types of cutting and sewing methods for putting an inseam on the center of the back slit part: to leave the whole inseam hemmed in the back center, to cut the left side of the inseam to the upper part of the back slit, and to cut the inseam to both the upper parts of the back slit. However, a method shown in most of the sampled text books is to cut the inseam of the back center to both the upper parts of the back slit. Third, the way of finishing a bottom edge hem in the text books is to do slip-stitch, herringbone stitch, and slinting hemming, in order after doing over-lock stitch, or to cut the hem on the bias and then slip-stitch, while for the consumer products the most frequently used sewing method is to finish the bottom edge hem by doing secoui-stitch. Finally, while in the text books the method of stitching darts and tucks is used for lining, the main lining method used in consumer products is to make tucks only. Also in the way of stitching the side seams of lining or the seams of the back center, there is a difference between the two sample groups of text books and the consumer products: while the former suggests using both open seams and over-lock stitch, the latter is found to finish the seams using an over-lock stitch only.
