    摘要： A process for the preparation of plexifilamentary film-fibril strands of synthetic fiber-forming polymer comprises the steps of generating a spin fluid and flash-spinning the spin fluid to form plexifilamentary film-fibril strands of the synthetic fiber-forming polymer. The spin fluid consists essentially of (a) 5 to 30 wt. % of a synthetic fiber-forming polymer, (b) a primary spin agent selected from the group consisting of hydrocarbons with 4 to 7 carbon atoms, and chlorinated, brominated and fluorinated compounds, and (c) a co-spin agent co-spin agent selected from the group consisting essentially of fluorinated organic compounds containing 4 to 8 carbon atoms and a double bond, and having an atmospheric boiling point of less than 100° C. The co-spin agent is present in the spin fluid in an amount sufficient to raise the cloud point pressure of the spin fluid by at least 50 pounds per square inch (345 kPa). A spin fluid used in the process of the invention is also provided.

    摘要： Polymeric structures produced with a controlled number and distribution of small, closed cells. The polymeric structures are characterized by an opaque, whitening appearance attributed, at least in part, to the distribution of closed cells and thus, at least in part, to light scattering resulting from the distribution of small, closed cells or voids. The light scattering thus provides an enhanced whitening effect. The whitening effect may be uniform or non-uniform along the length and width of the structure.
