Abstract
The present invention provides a method for transferring agglomerative short fibers such as natural fibers, ceramic fibers or metals, by means of a Coanda spiral flow produced by feeding a pressurized fluid. In this fluid-transfer, short fibers can be smoothly transferred with an orientation while causing swelling and dissociation of agglomerates thereof. The defects inevitable in the conventional transfer under turbulent flow conditions such as adherence of fibers to the inner wall of the pipe, agglomeration and breakage of whiskers are completely solved. High-speed oriented-transfer at a speed of several to 100 m/second is possible by means of the Coanda spiral flow.
