Abstract: This document describes biochemical pathways for producing adipyl-[acp] and either hexanoic acid or acetic acid from a long chain acyl-[acp] such as dodecanoyl-[acp] or octanoyl-[acp] using a polypeptide having pimeloyl-[acp] synthase activity and biochemical pathways for converting adipyl-[acp] and/or hexanoic acid to one of more of adipic acid, 6-aminohexanoic acid, 6-hydroxyhexanoic acid, hexamethylenediamine, caprolactam, and 1,6-hexanediol.

Abstract: The present invention pertains to a fluorine-free composition for treating textile articles being water repellant, sol resistant and stain resistant, especially carpets comprising a first composition comprising an aqueous silicone emulsion, an aqueous dispersion of a silane quaternary ammonium salt and water and a second composition comprising a soil repellency component that is an aqueous dispersion of colloidal organosiloxane copolymers.

Abstract: A multipolymer fiber comprising a polyester phase formed from at least one polyester resin, present at between about 50 to about 95 percent by weight and a polyamide phase formed from at least one polyamide resin, present at between about 5 to about 50 percent by weight, wherein the polyamide phase is distinct from the polyester phase and comprises a plurality of polyamide fibrils dispersed in the polyester phase, and wherein the polyamide fibrils are separately distinguishable from each other.

Abstract: This document describes biochemical pathways for producing methacrylate from precursors such as pyruvate via isobutyraldehyde and isobutyryl-CoA, using enzymes such as one or more thioesterases, transferases, or dehydrogenases, as well as recombinant hosts expressing one or more of such enzymes.

Abstract: A process for producing a partially balanced acid solution that involves metering dicarboxylic acid powder, based on weight, from a loss-in-weight feeder to a feeding conduit that transfers the dicarboxylic acid powder at a low variability feed rate into an in-line disperser, adding a first feed stream of diamine to the in-line disperser in an amount sufficient to form the partially balanced acid solution having a solids content of less than 60%, and storing the partially balanced acid solution at a temperature to maintain the dissolved dicarboxylic acid and to prevent formation of a slurry. The partially balanced acid solution may be used as a feed solution to prepare a nylon salt solution. Process controls for the process are also disclosed.

Abstract: The system and methods described herein solve problems of inaccurate flow control, loss of optimum reactant gas feed ratios, and the associated inefficiencies brought on by variable humidity in reactant feedstream gases during production of hydrogen cyanide by an Andrussow process.

Abstract: Embodiments of the present invention relate to methods for the biosynthesis of di- or trifunctional C7 alkanes in the presence of isolated enzymes or in the presence of a recombinant host cell expressing those enzymes. The di- or trifunctional C7 alkanes are useful as intermediates in the production of nylon-7, nylon-7,x, nylon-x,7, and polyesters.

Abstract: Disclosed are processes for application of dyes and topical chemistries to single yarns during a yarn rewind process. The process foregoes the need for downstream environmentally unfavorable dyeing and low PH chemical treatment processes on the finished carpet. Further, neutral pH dye solutions can be used instead of the prior art low pH dye solutions. The single, treated yarn can then be twisted, weaved and tufted, twisted yarn under dry conditions, and the twisted yarn subsequently weaved or weaved and tufted, into a finished fabric or carpet. Also disclosed are systems, BCF yarns, and carpets made from the BCF yarn treated by the disclosed processes.
