Stretchable textile materials are getting more widely used in clothing industry. Among others are two obvious reasons which make it so desirable to young female customers, i.e., better confort with motion and more closely fitted silhouette. But these two points cannot get along well always. If a manufacturer try hard to make his products too closely fit, then the products are even less comfortable than made of non-stretchable material. On the other hand, if a stretchable garment are developed to be too comfortable with plenty of size tolerance. it cannot attract customers who are looking for something closely fit. So the study was aimed to investigate appropriate size tolerances.

The purpose of this study is to analyze the wearing fitness of middle aged women's jacket with non-Stretchable Fabric and stretchable fabric. We surveyed the size of jackets and process of pattern making with stretchable fabric in companies which produce the clothing mainly for middle aged women. Based upon the result of process of pattern making, two kind of experimental jacket with non-stretchable and stretchable fabric were made. We measured space length between body and garment using 3D scanner and analyzed the clothing pressure 7 parts of body with 3 kinds of arm raising. The result were as follows : 1. Most parts of space length except bust were higher in non-stretchable jacket than in stretchable jacket. 2. Clothing pressure showed greater value with non-stretchable fabric jacket than with stretchable fabric jacket. Clothing pressure in upper arm point areas increased as the angle of the arm raising increased. Therefore, the sleeve width and armhole depth should he considered when the amount of wearing ease were reduced in jacket with stretchable fabric.

The purpose of this study is to analyze the ease of stretchable jackets which has been common since the mid-1990s and the whole actual conditions in making the lining fabrics. This can be done by investigating the actual conditions of domestic clothes businesses about the consumers. The outcomes of this study are as follows; The result of the survey in the differences of the ease between regular and stretchable fabrics shows that the pattern of designing stretchable fabrics needs diminishing the width of shoulder is 0.42cm, the whole girth chest is 1.83cm, the whole girth of waist is 0.88cm. It also shows that designing the ease of the whole girth of chest is 1.91cm to 2.54cm in the regular lining fabrics and is from 0 to 1.27cm in the stretchable fabrics more than the right side of fabrics. The ease of the whole girth of waist is similar to the round chest, in which the bottom sweep for garment is almost equal to the right side of fabrics in both regular lining fabrics and stretchable fabrics. The result of investigating the actual conditions of making the lining fabrics of stretchable jacket fabrics shows that 80% of a woman's wear brand produces and gives the pattern of the lining fabrics only for the special designing to the cooperative clothes manufactures. The business which always provides the patterns for the lining fabrics in the main office is only limited to 20%. Also, it shows that using the lining fabrics of stretchable jacket fabrics and regular lining fabrics together is 46.7%, the stretchable lining fabrics is 40% and the regular lining fabrics is 13.3% only.

The purpose of this study was to develop the construction process of orthopedic compression garments (OCG) for balancing of the left and right lumbar muscle power and strength to prevent low back pain. One male subject having low back pain was involved for investigating of the lumbar muscle power. EMG (Telemyo DTS2, Noraxon, U.S.A) was measured with/ without 3 types of waist assistant belt around the waist area of the subject. Based on the electromyogram value of left and right body, OCG were constructed as follows. Firstly, stretchable t-shirts type with supportive waist belt was selected for the convenience of wearing and laundering the OCG. The design lines of the front and back waist parts were created depending on the anatomy of the torso. Secondly, 3D pattern was developed using 3D Clo, RapidForm XOR, 2C-AN, and Yuka CAD program to increase the fit of the OCG. Finally, stretchable power-net was layered as linings in two ways, a single lining and double layered linings, and evaluated measuring lumbar muscle EMG by five subjects with low back pain. As the results, they were effective to balance the left and right lumbar muscle power and strength. Also the OCG with the double layered power-net lining was superior to the one layered lining in terms of fit and comfort.

This research studied how to develop tight upper sportswear from 3D scan data considering fabric stretch property. Subjects were five Korean men of average figure in their 20's. Scanning was done for ten postures via vitus smart/pro(Techmath LTD). Analyzing from 3D scan data, more than 70% of the upper body surface showed surface change rate under 20%. It was shoulder and under arm side part that showed most noticeable body surface change when moving. A parametric model with convex surface was generated and flattened onto the plane, resulting 2D pattern. The error rate occurring in the process of 3D to 2D conversion was 0.2% for outline and 0.13% for area, respectively. Thirteen kinds of stretchable fabrics in the market were collected for this study. Stretch property was in the range of 16.0~58.2% for wale direction; 23.1~78.4% for course. Based on wear trial test, four fabrics were chosen for making the 1st experimental garment and finally one fabric was chosen for the 2nd one, which was developed applying 4 kinds of crosswise reduction rate on 2D pattern: 0, 5, 10, and 15%. Through wear trial test and garment pressure measurement, experimental garment applied with 10% pattern reduction rate was evaluated as most comfortable and considerable.

This study was designed to analyze the three-dimensional shapes of Hanbok Chima made with various fabrics and to clarify the relationship between fabric properties as well as the objective and subjective evaluations of the 3D shape. For 3D shape data, a dress form (9A2 (N; nude)) was scanned with eight Chima garments made with the same number of fabrics. The scanner used was a non-contact three-dimensional human body measuring system belonging to Bunka Women's University in Japan. Data concerning the objective evaluation of the 3D shape was obtained from the measurements of the vertical and horizontal sections: those for subjective evaluation were through the sensory test after exposure to photographs from a front and side view. Four fabric factors were extracted from fabric physical properties: softness, extension, thickness of threads, and weight of fabric. Such factors as expansion (volume), sag of rear train, shape of nodes were influential in explaining the 3D shape of Hanbok Chima. From the analysis of the 3D shape, it can be deduced that with the constituent fabric stiffer, lighter, and less stretchable, the more expanded the 3D shape appeared to be. Multiple regression results showed that vertical shape factors have a greater effect on the evaluation of the 3D shape. It also implies that dependent variables of this study such as the subjective evaluation and 3D shape can be derived from regression equations on independent variables as fabric property factors or 3D shape factors. These results can enable the manufacturers to predict the 3D shape of the garment as well as the human subjective assessment to improve the efficacy of production. The investigation method proposed in this study can also be applicable to other garment items.
