    摘要： A process for selectively separating polyamides from multi-component waste materials including the steps of subjecting the multi-component mix to a specific mixture of caprolactam and water at a preselected temperature range below the degradation temperature of the polymer to be recovered, separating the formed polyamide solution, and recovering the desired polyamide. The process is very desirable for separating multi-component waste materials which contain not only nylon 6, but also nylon 6,6. The recovered polyamide may be used in molding applications and in fiber such as carpet fiber.

    摘要： Novel phosphate starch derivatives are useful in wound healing. Novel phosphorylated cottons are useful in wound healing. Silver-derivatized wound care products are provided which survive washing and remain part of the wound care product. Silver-derivatized wound care products are provided that have favorable elastase-sequestering activity while advantageously appearing white-colored, without needing to darken to grey or black as usually would occur when working with silver. Also, starch products with outstanding water uptake are provided.

    摘要： In a process for the production of heat stabilized nylon-6, hot nylon pellets are directly sprayed with measured quantities of concentrated solutions of copper salts and inorganic halides. For soluble cupric salts, the pellets are sprayed with a first solution comprising the soluble cupric salt and a second solution comprising the halide. Separate solutions are utilized when necessary to avoid precipitation problems. For cuprous salts solubilized in concentrated halide solution, a single solution may be prepared for spraying. Rapid absorption of copper by nylon eliminates precipitation and subsequent loss of the chemicals or discoloration of products.

    摘要： The present invention relates to a tufted fabric and a method of manufacturing the same. The tufted fabric generally comprises a primary backing and tufts mounted in the primary backing to form a fabric with a faceside having piles and a backside having loops. A thermoplastic polymer adhesive, which bonds the tufts to the primary backing, is formed by applying a reactive mixture comprising a polymerizable monomer to the backside of the tufted fabric and in-situ polymerizing the monomers to form the thermoplastic polymer adhesive. The process is particularly advantageous for the manufacture of recyclable tufted fabrics in which the adhesive polymer and tufts are formed from substantially the same polymer. The tufted fabric can be used in articles, such as, for example carpets, rugs and upholstery.
