Abstract:
A bundle of synthetic fibers for transporting aqueous fluids, wherein said bundle comprises at least two fibers, at least one of said two fibers having a non-round cross-section and a Single Fiber Bulk Factor greater than 4.0 and said bundle having(A) a Specific Volume greater than 4.0 cc/gm, (B) a Maximum Potential Flux for a bundle of fibers (MPFB)/Maximum Potential Flux for a single fiber (MPFSF) greater than or equal to 3.0, (C) a MPFB greater than or equal to 0.14 cc/(den*hr); and wherein said fibers have a lubricant coated thereon comprising 90 weight percent water and 10 weight percent solids component, said solids component comprising 10 weight percent solution of poly(polyethyleneglycol (1400) terephthalate), 44.1 weight percent polyethylene glycol (400) monolaurate, 44.1 weight percent polyethylene glycol (600) monolaurate, and 1.8 weight percent 4-cetyl, 4-ethyl morpholinium ethosulfate.
