Study on the Decline of Pressure on Girdle After Washing
A. Introduction
Girdle is a type of pressure garment to shape and smooth women’s figure from waist to thighs by compressing the fatty muscle to achieve the aesthetic appearance.
The girdles are made of elastic material. It adds pressure to the body and creates a nice body shape. Girdles mainly constructed by the warp knit power net and several layers with elastic power net to form different degree of pressure. A firm-control girdle will normally have more areas in which the fabric had been doubled to form a panel design that will have more controlling power. So the girdle must fit the body. However, some of the stress inside the pressure garment/ girdle will be relieved if the garment is under wash or wet by human perspiration with several times. Such decay is critical in changing the function of the pressure garment. In this project, we are aimed to find out the decay and the steady point of a pressure garment after several washes. As a result, suggestion can be raised to the manufacturer or user to wash the fabric before producing the pressure garment.
According to the above problem, below objective are set:
a) To analyze the decay of pressure after washing and to find out the steady pressure or mechanical properties after several washes.
b) To analyze how different washing media: water, detergent and physiological saline affected the change in pressure.
c) To find out the bias angle of an elastic fabric with which has the steadiest young’s mouduls
d) To discuss if the decline of pressure is critical for the manufacturers to have pre-washing before making the pressure garment/girdle.
B. Literature Review
The literature review is divided into four parts: materials used and optimum pressure for girdle, pressure measuring method, Predicting pressure exerted by pressure garment and pressure Decay on creeping and washing
1. Materials used and Optimum pressure for girdles
Girdles, the tight fitting clothing, are made from firm elastic
