Numerical simulation of the area shrinkage mass for the waist of elastic pantyhose by using FEM

Abstract

Purpose The area shrinkage of the body under pressure is very important to evaluate the comfort of pressure sense, and it is an important index that appraises compression garment. The purpose of this paper is to obtain the area shrinkage mass of the waist cross section by using the finite-element method (FEM), and the waist of women’s pantyhose could be designed with a different degree of elasticity during the course of design based on clothing pressure comfort. Design/methodology/approach This study aimed at the problems existing in the wearing of women’s elastic pantyhose, took the waist of pantyhose as the research object, and the contact between human body and pantyhose as elastic contact. The finite-element model of the waist cross section and elastic pantyhose fabric was acquired through CT scan and Mimics software. After simulating on the corresponding displacement distribution of the waist of sample elastic pantyhose during the process of dressing by using ANSYS, the authors divided the waist cross section into 24 equal regions according to angle (every 15 degrees as a region), and then the area shrinkage mass of each region was obtained by area calculation formula. According to the tendency of area shrinkage distribution, the waist of women’s elastic pantyhose could be designed for different regions of tension considering the pressure comfort, so as to guarantee that the wearing comfort can be maintained on the premise of ensuring the functionality of the elastic pantyhose. Findings In this paper, the authors obtained the area shrinkage mass of elastic pantyhose at waist cross section, and this area shrinkage distribution could be used as an objective evaluation index for pressure comfort. All these solutions are of great significance to the optimization design of pantyhose and can provide theoretical basis for the structural improvement of functional pantyhose and the prediction of clothing pressure. Originality/value This paper simulated the area shrinkage mass for the waist of elastic pantyhose by using FEM, and the waist of women’s elastic pantyhose could be designed for different regions of tension considering the pressure comfort according to the area shrinkage distribution tendency, so as to guarantee the wearing comfort during the wearing process.

Learning curve improvement model for sportswear comfort and sports functionality analysis

“…This study develops a reliable method to predict the pressure distribution of undergarments, which effectively provides parameters for undergarment comfort design. In the literature [12], finite element analysis software was used to construct a 3D model of the waist region of an athletic pantyhose and to determine the physical properties and parameters of the material. Then, they performed a mechanical analysis of the model and simulated the comfort of the waist region of the sports pantyhose in its natural state after being subjected to tensile forces.…”

Women’s jeans: influence of pressure in the sensation of comfort

“…Because of this, there are studies that try to understand the psychological effects of pressure from clothes as in the works. [19][20][21][22] Other works use numerical simulation to understand how the clothing interacts with the people as in the works of [23][24][25][26] or algorithms are used to try to predict the pressure on the body as in the work of Cheng et al 27 There are efforts to scale the size of clothing using technologies such as virtual reality 28 or 3D body scanning. 29 In relation to these concerns about the pressure on the body, there is already a study that attempts to design a pant that relieves the pressure when performing some movement, as in the case of Bragança et al, 30 research, where the highest pressures exerted were measured on the body and in these regions were placed reliefs.…”
