    Abstract: A spinning apparatus valuable for obtaining uniform ''''islandsin-a-sea'''' type composite filaments comprises a uniting chamber comprising a funnel-shaped space having a converging angle of at most 75*. 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. These means are effective for maintaining the ''''islands-in-asea'''' type composite stream in the uniting chamber at a favorable equilibrated condition for a long spinning period.

    Abstract: Die for forming composite filaments has several cores of one filament material dispensed in a matrix of a second material. The core streams discharge into a chamber which converges at an angle Theta of =75 degrees and which is fed with an annular and pref. also an axial stream of the matrix material. Pref. subsidiary passages sheath each core sub-filament in matrix material (co-axial or eccentric). For preparation of multi-core filaments or for manufacture of very fine filaments by subsequently removing the matrix material. Die design maintains stable core and matrix patterns throughout long prodn. runs - the flow path of the core filament streams is almost linear to avoid material hang-up and degradation. Sheathing of each core stream by matrix material avoids internal coalescence of the core streams.
