摘要: A fibrous material composed of multifilaments is forced out of a spinneret with a fluid to collide with an impingement plate thereby separating the filaments, said impingement plate having as its impinging surface a material which creates a negative electrical charge on the surfaces of the filaments of the fibrous material upon impingement. This greatly improves separation of the filaments and permits production of non-woven sheets with high uniformity.
