    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 cross-sectional 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.

    摘要: Disclosed is a method of copolymerizing polyethylene glycol (PEG) into polyethylene terephthalate (PET) to achieve a polyethylene glycol-modified polyester composition that can be spun into filaments. The method includes the steps of copolymerizing polyethylene glycol into polyethylene terephthalate in the melt phase to form a copolyester composition, then polymerizing the copolyester composition in the solid phase until the copolyester is capable of achieving a melt viscosity that facilitates the spinning of filaments, and thereafter spinning filaments from the copolyester. A copolyester composition comprised of polyethylene glycol and polyethylene terephthalate is also disclosed. Fabrics made from fibers formed from the copolyester composition possess wetting, wicking, drying, flame-retardancy, static-dissipation, and soft hand properties that are superior to those of fabrics formed from conventional polyethylene terephthalate fibers of the same yarn and fabric construction.

    摘要: Hydrophobic polyolefin fibers are provided with an internal hydrophobic polysiloxane of the formula in which X, Y, R1, and R2, which may be the same or different, or substituted or unsubstituted independently of each other, are aliphatic groups having not more than about sixteen carbon atoms, R1 and R2 also being selected from among aryl groups, and z being a positive number sufficiently high that the polysiloxane is hydrophobic (z is generally a least 10). The invention also provides a novel polymer melt for spinning these hydrophobic fibers. The fibers can be cut into staple lengths and carded and bonded to form hydrophobic woven and nonwoven products suitable for use in hygiene devices such as diapers. Such devices are improved by these fibers, which, as spun, present a greater hydrophobicity than melt-spun polyolefin fibers lacking the internal siloxane lubricant, the improved hydrophobicity is evidenced by an advancing contact angle for the as-spun fibers of at least about 95°.

    摘要: Fabrics containing melamine fibers are rendered more comfortable by carding the melamine fibers under vacuum so as to exhibit a narrower fiber diameter distribution (.delta..sub.d) and/or a narrower staple length distribution (.delta..sub.l) as compared to melamine fibers which are carded in the absence of vacuum. In addition, more comfortable melamine fiber-containing yarns are produced by spinning the staple fiber at a lower twist multiplier (TM) as compared to conventional melamine fiber yarns. Most preferably, the melamine fiber-containing fabrics and yarns will be blended with at least one other type of synthetic fibers, such as aramid fibers.
