APPARATUS FOR SPINNING SYNTHETIC {37 ISLANDS-IN-A-SEA{38 {0 TYPE COMPOSITE FILAMENTS

摘要

A spinning apparatus valuable for obtaining uniform "islands-in-a-sea" type composite filaments comprises a uniting chamber comprising a funnel-shaped space having a converging angle of at most 75 DEG . The apparatus may further include means for supplying the sea constituent polymeric liquid into a central portion and an outside portion of the uniting chamber, and means for incorporating the island constituent polymeric liquid with the sea constituent polymeric liquid in an eccentric manner.
