    摘要: Disclosed are processes for applying dyes, stain blocker and anti-soil compositions on BCF yarns during cable or air twisting processes, or heat setting processes, prior to weaving, knitting or tufting. Further discloses are process for applying dyes, stain blocker and anti-soil compositions on BCF yarns prior to heat setting. The processes forego the need to dye and otherwise treat carpets and other textiles made from the BCF yarn using current methods. Also disclosed are systems, BCF yarns, and carpets made from the BCF yarn treated by the disclosed process.

    摘要: The present invention provides a highly efficient process for manufacturing copolyether glycol having a mean molecular weight of from about 650 to about 5000 dalton by polymerization of tetrahydrofuran and at least one alkylene oxide in the presence of an acid catalyst and at least one compound containing reactive hydrogen atoms. More particularly, the invention relates to a process for manufacturing copolyether glycol which comprises recycle to the polymerization reaction step of at least a portion of the oligomeric cyclic ether which is co-produced with the copolyether glycol, said process exhibiting an Space Time Yield value of greater than about 0.9.

    摘要: The invention provides polyester polyol compositions and resin blends, useful as components of polyurethane and polyisocyanurate polymers, produced from cyclohexane oxidation reaction byproducts, such as water extracts and non-volatile distillation residues from the reaction. Such byproducts of industrial processes for preparation of adipic acid and caprolactam, important intermediates in the production of various types of nylon, have hitherto largely been used only as fuels. The present invention provides value-added products, methods for making, and methods for using the byproduct-derived polyester polyol compositions. For example, the invention provides polyurethane (PU) and/or polyisocyanurate (PIR) polymers made using the polyol compositions and polyfunctional isocyanates. The PU and PIR polymers can be used as adhesives, binders (e.g., for wood fibers), coatings (e.g., for controlled release fertilizers), and foams.
