20130284848 | SPUN YARN WINDING DEVICE AND SPUN YARN WINDING FACILITY - A spun yarn winding device includes a machine body; a turret; a feeding roller that is fixed to the machine body, is not in contact with winding bobbins, and feeds yarns to the winding bobbins at a speed equal to or faster than a winding speed; a traverse device fixed at an upstream side of an advance direction of the yarns relative to the feeding roller and which traverses the yarns; a peripheral speed detection unit that detects a peripheral speed of the winding bobbins; and a control unit that is arranged and programmed to perform a basic operation to maintain a free length of the yarns at a standard length by controlling a rotational angle of a turret during a yarn winding period, the free length of the yarns being located between the feeding roller and the winding bobbins. | 10-31-2013 |
20130157367 | NANOFIBERS WITH EXCELLENT BIODEGRADABILITY AND BIOCOMPATIBILITY AND METHOD FOR PRODUCING THE SAME - The invention provides a method for producing nanofibers of an aliphatic polyester resin (a biodegradable resin) with higher productivity than heretofore achieved, for example, without the need of cumbersome steps such as drawing and with operability at normal temperature. The method for producing nanofibers according to the invention includes (1) an extrusion step of extruding an organic solvent solution (S) into filaments in an aqueous solution (W) including a surfactant (SF) and water, the organic solvent solution (S) including an aliphatic polyester resin (A | 06-20-2013 |
