摘要
The pressure garment was used for different medical application such as treatement of hypertrophic scars, horsery anti-trombo ... There are two main types of pressure garment: Warp or werf knitted ready-to-wear garment and custom-made garment constructed by occupational therapists. For two types of productions, the fit of the garment is a major factor that determines the pressure exerted on the body so that the success or failure of the treatment. All most of pressure garment is producted by knitted fabric, which is considered as wrong dimensional stability. In the result, the fit of the garment in using is influenced. In this paper, we are investigating the dimentional stability of 1 x 1 cotton rib knitted fabric depending on some technological parametres such as the loop lengths and the ratio cpi/wpi. The 1 x 1 rib knitted fabric has been knitting in knitting machine with diametres of 26 inche and machine gause is 18, two kinds of cotton yarns Ne30 and Ne36 are used. The value of loop lengths and the ratio cpi/wpi have been 2.40, 2.50, 2.65, 2.80, 2.95, 3.10, 3.25 mm and 0.54, 0.55, 0.59, 0.61, 0.64, 0.61, 0.60 respectively for Ne30 cotton yarn and these values have been 2.30, 2.40, 2.55, 2.70, 2.80, 2.95 and 0.56, 0.59, 0.62, 0.62, 0.64, 0.65 respectively for Ne36 cotton yarn. Is was found that: for the 1 x 1 rib fabric knitted from Ne30 and Ne36 cotton yarn, the optimal values of loop length have been 2.50 and 2.40 respectively; the best value of ratio cpi/wpi has found 0.55 similar to 0.59. In these technological condidions the 1 x 1 rib knitted fabrics have good dimensional stability in reaching the equilibrium state and using process, so that they will assure a good fit for kniwear and for pressure gament, especially.
