Title:
GAS-STREAM SPINNING NOZZLE AND METHOD FOR PRODUCING GAS-STREAM SPINNING NOZZLE FOR MICROFIBER
Document Type and Number:
WIPO Patent Application WO/2010/095489
Kind Code:
A1
Abstract:
Provided is an inexpensive gas-stream spinning nozzle capable of stably forming a rotating gas stream by which a microfiber can be gas-stream spun. An air spinning nozzle (20), which is to be used for treating a microfiber (5) with a rotating air stream, is produced by the MEMS technique. The air spinning nozzle (20) is equipped with a substrate (1) in which a gas channel (4) for injecting a rotating air stream is formed. The gas channel (4), which consists of a concave of the substrate (1) in the thickness direction thereof in one side and another concave of the same in the other side, is shaped into a stepped hole so that the channel slopes as a whole along the thickness direction of the substrate (1).
