    Abstract: A spin dope composition produces a polymeric fiber useful in non- cryogenic gas separation. The composition includes polysulfone as the polymeric component, two solvents, in which the polymer is soluble, and a non- sol vent, in which the polymer is insoluble. The solvents preferably include N -methyl -pyrrol i done (NMP) and N,N-dimethyl acetamide (DMAC), and the non-solvent preferably includes triethylene glycol (TEG). Fibers made from the present composition have been found to exhibit superior properties of gas flux and selectivity, as compared with fibers made from spin dopes having only one solvent component.

    Abstract: A process of making staple fibers of poly(trimethylene terephthalate) includes feeding undrawn yarn (1) to a dip tank (2), forwarding by rolls (3, 4) and wetted under water. Wetted undrawn yarn (1) is forwarded by rolls (5, 6, 7, 8, 10) to a first drawing stage in a dip tank (9) and is partially drawn between rolls (10,11) under water in the dip tank (9). The yarn (1’) is then partially drawn by rolls (11, 12, 13, 14, 15, 16) which are driven at a faster speed than roll (10). The partially drawn yarn (1’’) is then rewetted by water spray jets (17) and is further drawn by rolls (18, 19, 20, 21) and puller rolls (22, 23) which are driven at a faster speed than roll (16). Nip rolls (5’, 8’, 14’, 22’, 25’) are used to minimize yarn slippage. After the second drawing, a finish sprayer (24) applies a dilute processing finish to the drawn yarn (1’’’), which is then forwarded and maintened under tension by puller rolls (25, 26) into a suffer box crimper (27) by driven crimper nip rolls (26’), where it is crimped and thermofixed by application of steam (28). The crimped yarn (1’’’’) is then forwarded in a relaxed state throuph a conventional belt dryer (29), cut by a rotary cutter (30) and baled (31) for storage and shipping.
