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.

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 verify how similar the virtual fit pants are to the actual fit of stretchable pants. Data is produced using a virtual model to apply movements. The results show that in the upright position, the similarity between the appearance of the actual fit and the virtual fit is high. Results are 4.47, 4.13 and 4.33 out of 5 on the front, side, and back, respectively. The base line of the front and back, and the amount of allowance in each part were well reproduced by the model. The texture of the virtual fit was evaluated and found to be similar to the actual fabric. In terms of shape and number of wrinkles with the virtual fit pants, large wrinkles were better expressed than fine wrinkles. After applying movements to the virtual model, the front and side results were similar to the actual fit, but the back results were different. As a result of multiple comparisons, the greatest difference in similarity by movements is found in the center front line. The similarity difference was lower on the side than on the front. The only significant difference after applying movements is in the hip circumference margin. According to movements, the similarity of virtual fit is lower on the back than on the front and side, and the back also has the largest similarity differences to the movements type.

This study aimed to produce fiber stretch sensors for smart soccer socks to prevent injuries during training. A sensor was manufactured with stretchable fabric and tested to ensure convenience during training. In order to manufacture the fiber stretch sensor, a CNT dispersion solution was applied to an e-band and elastic polyester fabric, and the performance of the sensors was evaluated by a tensile test. Performance evaluation showed that both of the tested fabrics are excellent for this purpose. Both sensors were attached to socks to create prototype wearable devices, and an experiment was conducted to determine whether a resistance change accompanying relaxation and contraction of the gastrocnemius muscle could be detected. In order to accurately evaluate performance as a sensor, the fabric was stretched 20 times at low speeds of 1 Hz and 0.5 Hz. A change in resistance due to tension was observed, with both the E-band and the stretchable poly fabric showing high sensitivity and high reproducibility. Both can be used as relaxation/contraction sensors. Smart soccer socks were made using the two materials, and an evaluation was conducted. Tensile tests were done on the smart soccer socks; the tests were done 20 times per sock, and the sensor showed a stable resistance change between 30 and 40 ohms depending on the tension of the sensor. As a result, we confirmed that smart soccer socks with stretch sensors made of E-bands can measure changes in the gastrocnemius muscle.

The purpose of this study is to examine the inconvenience when putting on stretch pants and to compare and analyze the pattern making method of pants made of the stretch and non-stretch fabric to develop functional and good looking stretch pants. For this study, we conducted a survey of women in their twenties and collected the basic data and master pattern through material of a woman's wear brand and the interview and questionnaires. The results of this study are as follows. First, the survey result for the woman consumers showed that pants were estimated as the most uncomfortable item among the stretch clothes and when they put the stretch pants on, the most uncomfortable parts of out-shell were the hip girth and rise. Secondly, the result of pattern making method of the pants was as follows. The ease of the stretch pants pattern was 0cm in the waist girth and -1 to -1.5cm in the hip girth more than non-stretch pants. The ease in crotch, inseam and outseam length was 0cm for both.

The purpose of this study was to examine the inconvenience when putting on stretchable pants and to analyze the whole actual conditions of making of the lining fabrics. For this study, we conducted a survey of women in their twenties and collected the basic data and master pattern through material of a woman's wear brand and the interview and questionnaires. The results of this study were as follows. First, the survey result for the woman consumers it showed that the most uncomfortable problem about the lining of pants was not sufficient stretch as much as the out-shell. Secondly, it was shown that many brands(46.7%) were using the lining fabrics of stretch clothes mixed with 'non-stretch fabrics' and 'stretch fabrics'. The result of lining pattern making for the stretch pants showed that the ease of the lining fabrics was 0 to 4cm in the hip girth more than out-shell. The ease in crotch width was 0 to 1.3cm for lining fabrics. But in the stretch lining fabrics the ease for front crotch width was 0 to 1cm more than out-shell. The lengths of crotch rising were -0.7 to 1.3cm for the non-stretch lining fabrics and -1 to 1cm for the stretch lining fabrics.

This study aimed to determine the effects of the shape and attachment position of stretchable textile sensors coated with carbon nanotube on their performance when used to measure children's joint movements. Moreover, the child-safe requirements for fabric motion sensors are established. The child participants were advised to wear integrated clothing equipped with the sensors of various shapes (rectangular and boat-shaped) and attachment positions (at the knee and elbow joints or 4 cm below the joints). The voltage change induced by the elongation and contraction of the fabric sensors was determined for arm and leg flexion-extension motions at 60 deg/s (three measurements of 10 repeats each for 60°and 90°angles, for a total of 60 repetitions). Their dependability was determined by comparing the fabric motion sensors to the associated acceleration sensors. The experimental results indicate that the rectangular-shaped sensor affixed 4 cm below the joint is the most effective fabric motion sensor for measuring children's arm and leg motions. In this study, we designed a textile sensor capable of tracking children's joint motion and analyzed the sensor shape and attachment position on motion sensing clothing. We demonstrated that flexible fabric sensors integrated into garments may be used to detect the joint motions of the human body.

This study analyzes the stretchability and clothing pressure of fabrics made from stretchy knit materials, and uses the baseline data to develop various functional clothing made from stretchy knit fabrics. To observe the changes in the stretchability and clothing pressure, we observed the compatibility of the two materials (tricot and power-net), presence of flat seam, fabric layering, and flat seam direction as key variables. A standard test method for stretch properties (ASTM D2594) was used for measuring the stretchability of the material. Clothing pressure measurements were analyzed in terms of the mean and standard deviation values, and the correlation of the stretchability. In the case of tricot, the presence of flat seam increased the stretchability of the fabric regardless of the fabric layering. However, when tricot and the less stretchable power-net were combined, the presence of flat seam did not increase the stretchability. Flat seam did not interfere with or limit the stretchability of the fabric, but they did increase the clothing pressure at the seam. The stretchability had a negative correlation with the clothing pressure except along the flat seam.

The purpose of this study is to analyze present the pattern making of the lining fabrics calculating the right ease and rising quantities of arm-hole when the pattern of the lining fabrics of stretchable jacket fabrics is produced. The outcomes of this study are as follows. The right ease of lining fabrics was not room of 0cm as patterns being same the right side of fabrics in the girth of the chest, waist, and the edge of a garment and gets the most excellent valuation, and then the girth of the chest, and waist was applied to 2cm and around the edge of a garment 0cm in regular lining fabrics. In addition to, although the ease of patterns of the lining fabrics was more, it was not necessarily to satisfy. The result of the valuation according to the quantities of rising arm-hole of the pattern of the lining fabrics showed that the making lining fabrics that the quantities of rising arm-hole was 0.8cm in the body and 1.2cm in the sleeve in the both the stretchable fabrics and regular lining fabrics was the most excellent thing, and then 0cm in the body and 2cm in the sleeve, and then 0cm in the body and 0cm in the sleeve. The valuation of external appearance on the quantities of rising arm-hole was recognized similarly because of being rarely significance level, but around the chest and waist was recognized as being significance level in wearing satisfaction.
