Effects of Novel Color Polyurethane Yarn on the Aesthetics of Legs in Pantyhose
Aesthetic property Anisotropic property Color polyurethane yarn
2009/5/8
To improve the aesthetic appeal of pantyhose, the design and development of a new product and a wear experiment were carried out. The sheerness and visual impression of circular plain knitted fabric...
Air Drag Force on a Yarn and Use of a Coaxial Jet for Yarn Operation
Yarn operation Air drag force Coaxial circular jet Coaxial annular jet Power-saving
2009/5/5
we calculated numerically compressible airflows past a yarn in a thin pipe in order to operate yarn using both a circular jet and an annular jet. We proposed the way to arrange air drag coefficients o...
