Technical Design of Tight Upper Sportswear based on 3D Scanning Technology and Stretch Property of Knitted Fabric

Abstract

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.

Knit Structure and Properties of High Stretch Compression Garments

“…의복의 착용으로 인해 인체가 느끼는 의복압(clothing pressure)은 의복의 구속성과 운동기능성을 결정하는 중요 한 요인이 될 뿐만 아니라 의복의 착용 쾌적성능과도 밀접 한 관계가 있다 [1]. 적절한 의복압은 신체 일부의 불필요한 동작을 막아 운동성을 최대화시켜 주며, 근육을 감싸 받쳐 줌으로써 신체를 보호하는 역할을 할 뿐만 아니라 [2], 외과 수술환자나 화상환자의 상처부위에 적절한 압박을 가함으 로 해서 상처부위를 부드럽게 하며 피부조직 재생에 도움 을 줄 수 있다 [3]. 신체에 [4].…”
