Although 3D simulation became universal in many fields, including architecture and machinery, with the development of IT technology, it hasn't become universal in the clothing field yet. A 3D apparel CAD program is used to reduce personnel expenses, economize resources, and protect environment in this clothing industry. It is to simulate several designs on 3D apparel CAD to manufacture the final design alone as a sample.
The purpose of this study is to perform comparative analysis of differences between clothes simulated by 3D apparel CAD and actually-manufactured clothes to find out things to improve and complement in the 3D apparel CAD program.
For this purpose, attempts are made to see:
1. If a 3D apparel CAD program can easily express the whole silhouette of an actual manufacture.
2. Properties of a 3D apparel CAD program manufacture and actual one in front, back, right, and left parts.
3. The degree of expressing physical properties of fabric of the actual manufacture by the 3D apparel CAD program manufacture.
After testing physical properties of thin, low-elasticity cotton stuff, soft, low-elasticity, glossy polyester silk satin stuff, and thick, tough-touch woolen stuff by using a KES-FB-AUTO-A SYSTEM, one-piece dresses were made with each stuff into the 3D apparel CAD program manufacture and the actual manufacture and printed into pictures; then, a sensory test was carried out with 44 questions in terms of front, back, right, and left parts with 30 persons―clothing majors and fashion school students. With the results, comparative analysis was made on differences in silhouette between two stimuli.
With a woman with 6cm difference between front and back length as a subject, items necessary to make a one-piece dress were selected and measured according to the criteria of “2004 Size Korea.”
The experiment procedure is as follows:
1. Select a design needed for the research.
2. Test physical properties of fabric for manufacturing clothes and input data about the physical properties.
3. Take the measurements of the model and input them in the body.
4. Use the measurements to manufacture a pattern with 2D apparel pattern CAD.
5. Use data about the body of the model, physical properties of fabric, and the pattern manufactured in 2D to manufacture clothes with a 3D simulation program.
6. Print the inputted pattern data to manufacture actual clothes.
7. Make a comparative research on general silhouette expression, physical property expression of fabric, and expression of each part between 3D-manufactured clothes and actually-manufactured clothes.
Data analysis was carried out with the mean of the results of the sensory test.
From the results, the following conclusions were drawn:
1. Since the difference between clothes manufactured by 3D apparel CAD and actually-manufactured clothes was more than 4.00 on the average, 3D apparel CAD was found to have no difficulty in expressing the general silhouette of actually-manufactured clothes.
2. Since the difference between clothes manufactured by 3D apparel CAD and actually-manufactured clothes was on the average 3.80 for the front part and 3.75 for the back part, as compared with 3.66 for the left part and 3.70 for the right part with needlework seen, it is necessary to improve expression at parts of needlework.
3. The 3D program should improve expression of physical properties of fabric to express the curve of body and folds more accurately.
Future researches should select fabric in the same color to reduce errors caused by color difference of fabric and use the body in the same posture as 3D apparel CAD to reduce errors caused by the posture.
It is expected that this study, which made comparative analysis of differences between clothes simulated by 3D apparel CAD and actually-manufactured clothes and found out things to improve and complement in the current 3D apparel CAD program, will be used as a fundamental research to develop a better 3D apparel CAD program.
