“…Thermophysiological comfort is closely related to the thermal balance of the body, which depends on environmental and personal factors and clothing parameters. 7,8 Air, heat and moisture transfer management are important factors in this comfort. [9][10][11] In the case of elastic warp-knitted medical garments, they are required to be stable and maintain the level of compression and assure the product's comfort for the duration of use, as well.…”

The aim of this study is to determine the performance properties of elastic warp-knitted fabrics used for medical purposes. The samples were knitted using different weft yarn material and changing the threading order of elastomer yarn. The detailed results of the dimensional and elasticity performance of elastic warp-knitted fabrics had been reported in Part I of this series. In this part, the effects of weft yarn material and the threading order of elastomer yarn on the thermal comfort characteristics were investigated. It has been seen that the type and linear density of the transverse weft yarns and the number of elastomer yarns in the fabric structure affected significantly the thermal comfort and permeability characteristics of the developed elastic warp-knitted fabrics. According to the results, using polyester yarns as weft and reducing the number of elastomer yarns led to an increase in air permeability. Additionally, the thermal conductivity characteristics of the fabrics increased as the number of elastomer yarns in the structure increased. It has been seen that from the results, the water vapour resistance coefficient of the samples is appropriate for the usage of these fabrics in medical products.

“…The reduction factor method refers to select a standard reduction factor (generally 10%, 15% or 20%) firstly, and then calculate the sizes of compression garment based on the sizes of human body. The design method for compression garment based on Laplace law considers the fabric properties as well as the body sizes, easy to implement, having low cost and high popularization value [5]. There were two kinds of stretch fabric in use, namely, comfort stretch (25 -30%) and power stretch (30 -50%).…”

Compression garments are used for medical therapies and sports products such as bandages, socks, workout clothes and so on, with different degrees of compression. The pressure exerted on the body by compression products must be measured and calculated during the design. This paper investigated a method to determine the required pressure in the design of legging pants with a given abdominal pressure by using knitted CVC fabric (60% Cotton and 40% Polyester) with all stitches plated with 100% Spandex yarn. The pressure was calculated based on Laplace laws and was checked by using the designed FSR402 force sensor. Eight volunteers have participated in the trial. Calculating the volunteer's abdominal pressure in wearing legging pants using Laplace's formula was resulted in a range of 5.0 mmHg to 5.7 mmHg when the fabric extension was 20% and between 7.1 mmHg and 8.0 mmHg with a fabric extension of 35%. In that case, the actual pressure measured by the force sensor FSR402 was from 24.3 mmHg to 27.6 mmHg at 20% fabric extension and from 34 mmHg to 39 mmHg at 35% extension. Research shows that using the Laplace equation requires correction to fit a particular design with different circumferences.

In recent decades, sports and medical products, such as compression underwear and stockings, have been increasingly receiving more attention as more and more urbanites are beginning to focus on their health issues. In terms of compression garments, inverse relaxation takes place with frequent wear. Pressure retention on leg, body shaping, and muscle movement control during activity are highly related to this phenomenon. Elastic knitted fabrics are widely used for sportswear clothing. They have good mechanical and dynamic properties, which include good elasticity, recovery, tensile strength, etc. These properties have been extensively and recently studied by different researchers. However, the inverse relaxation of elastic knitted fabric is not a topic of study in the literature. In response to the research gap, this study systematically investigates the inverse stress relaxation of elastic knitted sportswear. A theoretical model is applied and validated through a series of experiments. The factor that affects the process of inverse relaxation and the relationship between relaxation and inverse relaxation are analyzed both theoretically and experimentally. The mechanism behind the structural deformation of elastic knitted fabric can then be intuitively revealed. This study therefore provides a new perspective for improving sportswear performance through fabric stitch design and engineering.
