Abstract
Abstract Graduated compression is widely used for medical application to prevent perioperative venous thromboembolism, but other applications such as sportswear can potentially also benefit from it. A tight-fit cycling shirt meant to ensure the correct position during cycling and prevent injuries was designed. The aim of this study was to improve garment pattern design from the aspect of clothing pressure for providing support and enhancing comfort to the user. This paper investigates the suitability of pressure maps from 3D fashion design software CLO 3D for design and in particular its capability to discriminate between various materials and cycling postures. Moreover, the impact of the mechanical properties of fabric was analyzed. In particular, virtual prototyping tool CLO 3D and pressure mapping were employed to achieve the required graduated compression while ensuring fit and comfort. Pattern adjustments were iteratively performed until stress, strain, and pressure maps showed adequate fit and pressure of the cycling garment on the virtual cyclist in static and dynamic cycling positions. The impact of fabric types on garment fit has been shown by generating the stress, strain, and pressure maps with a virtual simulation. It was found that the visualized pressure on the human body model shows distributions that are related to contact between body and garment, and large compression stresses occur in the lower parts of the two shirts. Evident garment deformation was shown at hip level, upper arm, lower front side seam, and front neck, which can reduce garment wear comfort and freedom of movement. The output was found to be sufficiently accurate to optimize the garments based on material and cycling posture.

In this study, we measured pressure exerted by fabrics A and B, with the original patterns, and the results show lower pressure in case of Fabric A, which can be due to entirely different mechanical properties of the two fabrics (Table 1), where A is a stretch fabric
Summary
Garment fit and pressure comfort have been identified as among the important attributes for tight-fit sportswear [1]. Compression is a result of forces generated during dynamic interactions between the body and forces involved in the garment strain and induce pressure sensations. Both the applied pressure and the way pressure changes during use are important to understand. Li et al (2005) analyzed the possible reasons influencing the stocking pressure performances and found skin pressure distributions and magnitudes applied by graduated compression stocking were significantly determined by the specific locations of testing points and potentially influenced by the pressure sensor and testing methods [10]. Clothing pressure can be assessed by many different kinds of methods, including theoretical calculations [11], simulation [12, 13], and direct and indirect tests [14, 15]
