Predictive modelling of compression garments for elastic fabric and the effects of pressure sensor thickness

Abstract

This research has been conducted to develop mathematical models to predict the compression pressure and strain value of fabric based on Laplace's law. The experiment was designed in accordance with the strain values of stretched fabric in order to make prediction of compression pressure. The fabrics covered on rigid cylindrical models and thigh part of human body were compared and measured for pressure values using compression tester. The results revealed that pressure values on rigid body were overestimated which may result from the cause of sensor thickness. Later, correction factor was included in calculations in order to get rid of the overestimated pressure. It was also found that predicted pressures were close to the ones being measured on rigid body by compression tester after multiplying with the correction factor, while soft tissue surface had no influential effect on pressure perturbation and pressure-measured values were close to the predicted pressure values obtained from modelling.

Fit and Pressure Comfort Evaluation on a Virtual Prototype of a Tight-Fit Cycling Shirt

“…The collar, neckline, lower front region/hip level, and sleeve fi t badly and result in high clothing pressures, so the patterns need great adjustments (i.e., eight spots of poor fi t and four spots of tight fi t area, represented with red and yellow, respectively, for both fabrics). As shown in Table 2, pressure points correspond to the lower and neckline front panels, and Previous studies have demonstrated the infl uence of fabric mechanical properties on clothing pressure [32,33]. Also, 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.…”

Pressure and Electromechanical Behaviors of Elastic Pressure Exerting and Sensing Fabrics for Monitoring Pressure of Compression Textiles

“…According to previous research, [1,46] length C corresponds to the width of fabric section that is in contact with the press head during pressing. Therefore, T is the garment tension per unit of length, which is expressed by Equation (8).…”

“…r (m) represents the radius of the press head, and L 0 is the gauge length of two fabric holders, which is equal to the initial length of fabric specimen. L is the total length of fabric sample between fabric holder after being pressed under stress, described as Equation (1).…”

“…Compression textiles are functional textiles that can apply pressure to specific areas of the human body for a variety of purposes, [1][2][3] which are commonly made by using extensible and elastic woven and knitted fabrics. When the extended fabric is worn, such as on a cylindrical shaped limb, internal stress will be generated in the fabric, and thus the resultant interfacial pressure will be exerted onto the body.…”

Predicting Compression Pressure of Knitted Fabric Using a Modified Laplace’s Law

“…The predictive pressure values of the stretch fabrics were calculated by applying Laplace’s law [ 32 , 33 ]. In the investigation, the geometric form of the PVC cylinder ( Figure 6 ) was assumed to represent the human body figure (arm).…”
