  • Latex suspension process and graft polyblend composition using small particle size spine
    Patent number: 4042647
    Abstract: Disclosed is a novel polybutadiene or butadiene-styrene copolymer based gum plastic having excellent impact strength and a method for its preparation. The use of small particle size (SPS) spine latex in a latex-suspension process gives unexpectedly good properties by yielding an ABS with at least about 85% of the rubber present as particles within a specified and relatively narrow size range, i.e., 0.04-0.25.mu. and having a number average particle size less than 0.14.mu.. In the method of preparation, the latex spine and monomers are converted directly to the final product by a conventional suspension process.

  • Method and apparatus for producing plied yarn and product thereof
    Patent number: 4034544
    Abstract: A method and apparatus for producing either bulked continuous filament or spun staple yarn in one continuous operation are disclosed. In the method, a first single end of either continuous filament or spun staple yarn is ballooned about and plied with a like second single end of yarn while both are under tension and advancing at a common linear speed. A higher tension is utilized during the plying operation. The plied yarn is then subjected to heat while the tension is relaxed, followed by a cooling and drying stage, to enable the yarn to be twist-set in a bulked condition, with the component single ends substantially free of any twist memory. This abstract is not to be taken either as a complete exposition or as a limitation of the present invention, however, the full nature and extent of the invention being discernible only by reference to and from the entire disclosure.
