    摘要： Methods for preparing composite non-woven fibers-in-fibers, otherwise referred to as composite polymeric fibers having an island-in-sea morphology, are described. The composite polymeric fibers may be prepared by a method that includes melt-blowing a blend of a first polymer and an immiscible second polymer to form the composite polymer fibers. The first polymer forms a matrix that surrounds the second polymer. Typically, the second polymer forms nanofibers within the matrix of the first polymer. The composite polymeric fiber may be treated with a solvent that selectively dissolves the matrix of the composite polymeric fiber and that does not dissolve the nanofibers of the composite polymeric fiber, and the nanofibers then may be collected for further treatment or use.

    摘要： An apparatus for forming a polycomponent fibre having a first, fibre forming component comprising a polymer, and a second, component comprising an active ingredient that will selectively reduce or remove components of tobacco smoke. The apparatus has a first reservoir for containing the first component, and a second reservoir for containing the dispersion, second solution or liquid. The dispersion, second solution or liquid includes the second component. The apparatus also has a polycomponent spinnerette adapted to coextrude the first component and the second component to form the polycomponent fibre. The apparatus also includes a first conduit for connecting the first reservoir to the spinnerette, and a second conduit for connecting the second reservoir to the spinnerette.

    摘要： Polyester feed yarn for drawtexturing, having an elongation at break of 30 to 150 percent, is composed of three different types of filaments. (A) 20 to 40 percent of the filaments consist of a polymer of ethylene terephthalate and 0 to 3 mole percent of modifying groups for imparting cationic dyeability. (B) 20 to 40 percent of the filaments consist of a copolymer of ethylene terephthalate and about 5 to 15 mole percent of other ester units. (C) 15 to 35 weight percent of the yarn consists of eccentric bicomponent filaments of the above two polymers. The bicomponent filaments have a smaller denier and lower elongation at break than the other filaments, so that the bicomponent filaments can be broken preferentially when the yarn is drawtextured to provide spun-like tactility. When broken, the bicomponent filaments helically crimp and become entangled in the yarn bundle with a slight, uniform protrusion of ends above the surface which provides good resistance to pilling in fabrics.
