Fabrics shrinkage are affected by weaving conditions and are very difficult to be estimated when the amount of fiber consumption and production are calculated. Therefore, we need to standardize fabric shrinkage according to various weaving conditions. To develop the new textile products, we collected and analysed data of fabric shrinkage with the weaving conditions including fabric density and woven structure, tension, and machinery used.

This research surveys the differences of fabric mechanical properties according to the different looms and the fabric positions with relation to warp and weft weaving tensions on the Picanol and Omega looms respectively. For this purpose, the grey fabrics woven in the previous paper are processed in dyeing and finishing processes, and the processing shrinkages are measured on each processes such as dryer, scouring, pre-set, dyeing and final-set using the fabric density and width. The mechanical properties of the finished fabrics are measured and discussed with relation to the warp and weft weaving tensions of the two looms and the variations of the fabric mechanical properties according to the fabric positions are also discussed. In addition, the fabric thickness according to the fabric positions such as right, left selvedges and center of the fabrics is also measured and discussed with the characteristics of the Picanol and Omega looms.

Modern Japan has been known as the country manufacturing Shin-gosen that denotes Japanese synthetic fiber. Japan has long traditon of weaving and dyeing of local traditional Textiles. Japanese traditional weaving and dyeing methods have been handed down through hundred years and various type of textiles have been fabricated in different regions. Japanese modern worldly famous fashion designers are recognized by using the Japanese traditional textiles. Traditional textiles of Japan are inherited in the present age and become the source of inspiration for modern Japanese fashion designers. This research investigated the originality and modernity of 10 kinds of main Japanese traditional textiles by design servey, 5kinds of weaving methods and 5kinds of dyeing methods. The 5kinds weaving methods include Kasuri, Shima, Cizimi, Zohu, Chumugi and 5kinds dyeing methods include Izome, Katazome, Tuzukaki, Uzen, Shibori dyeing.

In weaving welding where a V groove exists, the heat input distribution is an important factor that determines the defectiveness of the bead shape, undercut and over-lap. In this study, the amount of heat input, which is determined by the welding current, voltage, speed and weaving conditions is calculated through numerical methods. Furthermore, the heat input distribution as a two- dimensional heat source was observed when applied to each groove. Therefore, a heat input control algorithm is suggested to prevent the defects generated from undercut or over-lap, which was verified through an analysis of the heat input distribution.

The air-jet loom represents a major step in the development of shutterless weaving due to its ability to weave a wide range of yarns at high speeds. The air-jet weaving involves inserting a pre-measured length of yarn through the wraps, which is shed by means of compressed air. The analysis of air flow characteristic of the main nozzle and acceleration tube is required for improving the loom performance. In this paper, we examined the effects of the main nozzle with different acceleration tubes as well as diameters. Also, we compared the performance of a straight-type tube with a Laval-type tube and the effect of installing a suction hole on the acceleration tube.

The Air-jet loom represents a major step in the development of shutterless weaving due to its ability to weave a wide range of yarns at high speeds. The Air-jet weaving involvers, inserting a pre-measured length of yam through the wrap, is sheds by meads of compressed air. The analysis of air flow characteristic of the main nozzle and acceleration tube is required for the loom performance. h this paper We examined the effect of the main nozzle with different acceleration tubes as well as diameters. And also, we compared the performance of straight type tube with laval type tube and of according to be suction hole on the acceleration tube, respectively.

In GMA welding processes, bead contour and penetration patterns are criterion to estimate weld quality. Bead geometry is commonly defined with width, height and depth. When weaving is taken into account, selection of welding conditions is known to be difficult. Thus, empirical or trial-and-error method are usually introduced. This study examined the correlation of welding process variables including weaving parameters with bead geometry using srtificial neural networks(ANN). The main task of the Ann estimator is to realize the mapping characteristics from the sampled welding process variables to the actual bead geometry through training. After the neural network model is constructed, welding process variables for desired bead geometry is selected by inverse model. Experimental varification of the inverse model is conducted through actual welding.

In torch weaving in arc welding on V groove, the heat input distribution on groove surface is a main factor determining the bead shape and the weld quality with and without the weld defects such as undercut, overlap, etc. In this study, we calculate the heat input varying with the welding current, arc voltage, welding speed and the touch weaving condition using numerical method. And we investigate the heat input distribution on groove surface while applying the various grooves having 2 dimensional heat sources.
