Abstract
In this article, we build an oval mechanical model at any circumference of seamless weft, founded upon the analysis of body shape in order to analyze the curvature radius at arbitrary circumference and part. Clothing pressure is built according to the Laplace equation. Depending on the elastic fabric tensile deformation, clothing pressure at any circumference was subsequently analyzed. The results demonstrate that clothing pressure increases in areas of largest body curvature, which is highest on both sides but is smallest on the body front center and back center. In addition, weft flexible fabric sensors, which are knitted silver-plated yarn into seamless underwear as pressure sensors, are designed to test the relationship between sensor’s resistance and the clothing commodious quantity in order to explore the relationship between resistance change and clothing pressure. The results show that as the size of those wearing a given garment changes, the resistance of the flexible sensor in the clothing will also change. Specifically, weight and size are associated with greater clothing pressure and higher resistance of the flexible sensor. Because clothing pressure and flexible sensor resistance are linked to the tensile tension of clothing, we have been able to determine the relationship between clothing pressure and flexible sensor resistance. This achievement is expected to provide the basis for further studies assessing the comforting pressure of seamless underwear and ease of wear.
Highlights
With the improving living standards, people have higher demands for the comfort level of their clothing
The relationship between the tensile tension and the transverse tensile strain of the knitted flexible sensor integrated in the seamless underwear was measured by the KES drawing instrument
It can be observed that the tensile tension of the knitted flexible sensor increases linearly with the increase of strain
Summary
With the improving living standards, people have higher demands for the comfort level of their clothing. Seamless underwear is considered to be “the second skin of the human body.”[1] The use of colored yarn to make garments reduces the dyeing process, saves energy, and reduces emissions. It creates economic benefits, and it provides social benefits and meets the requirements of the green economy.[2] Clothing pressure comfort is the key factor to judge its comfort, and suitable critical clothing pressure is both the essential problem and the index of clothing design.[3] Clothing pressure cannot be too small or too large. High clothing pressure may affect the skeletal development of children and may even result in physical deformities.[4]
