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.

摘要:
In one embodiment the invention is an article comprising at least two layers, a first or low crystallinity layer comprising a low crystallinity polymer and a second or high crystallinity layer comprising a high crystallinity polymer. The high crystallinity polymer has a melting point as determined by differential scanning calorimetry (DSC) that is about the same or within less than 25C of the melting point of the low crystallinity polymer. The article is elongated at a temperature below the melting point of the low crystallinity polymer in at least one direction to an elongation of at least about 50% of its original length or width, to form a pre-stretched article. Preferably, the high crystallinity layer is capable of undergoing plastic deformation upon the elongation.
摘要:
A micro staple fiber nonwoven fabric, characterized in that it comprises staple fibers having a single fiber fineness of 0.0001 to 0.5 dtex and a fiber length of 10 cm or less, has a weight of 100 to 550 g/m2, and has an apparent density of fiber of 0.280 to 0.700 g/cm3, a tensile strength of 70 N/cm or more and a tear strength of 3 to 50 N. The micro staple fiber nonwoven fabric is suitable for use in a leather-like sheet and, and can be used for providing a leather-like sheet excellent in the sense of fullfilment.

摘要:
New nonwoven fibrous webs are taught which comprise a collected mass of a) directly formed fibers disposed within the web in a C-shaped configuration and b) staple fibers having a crimp of at least 15% dispersed among the directly formed fibers in an amount of at least 5% the weight of the directly formed fibers. The web is lofty but free of macrovoids. Preferably, the web has a filling ratio of at least 50 and a light transmittance variation of about 2% or less. Typically, fibers within the web are bonded together at points of fiber intersection, preferably with autogenous bonds, to provide a compression- resistant matrix. The webs are especially useful as acoustic and thermal insulation.
