摘要： 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.
