Fractal polyester has distorted gene of similar nature fiber that can produce nature distort by digital fractal enlargement. Fractal polyester/cotton blended yarn is made of nature cotton fiber and a little polyester filament with fractal structure by doubling and twisting machine. The fractal polyester/cotton blended fabric characterizes super nature fabric that the inner is fractal polyester filament with good shape retention, while the outside layer is cotton fiber. The study discussed spinning and weaving technology of fractal polyester/cotton blended fabric. The key technology of spinning is twisting process of cotton yarn and fractal polyester filament, which evenly adjusts two kinds of yarn tension. In order to stabilize the doubling yarn effect with "Dragon Chanzhu", yarn steaming technology is necessary, which steaming time are 40 minutes, steaming temperature is at 110°C-140 °C. Sizing and Weaving processes ensure fabric quality and productive efficiency. So choose "small tension, low elongation, good coating property, pressing yarn hairiness" as sizing process route process route, and choose "early shed timing, high back beam, large shed opening " as weaving process. |
