Abstract: Included are segmented polyurethane elastic fibers or spandex fibers, capable of bonding to polymer fiber such as nylon or polyamide fibers, in addition to bonding to itself, for apparel textile applications. More particularly the invention relates to bicomponent spandex fibers, with a heat resistant core and a heat sensitive sheath, spun from polymer solutions. The nylon fabrics containing such spandex fibers have enhanced stretch performance and improved surface appearance after heat treatment to activate the fusing and bonding between nylon fibers and spandex fibers.

Abstract: The present disclosure provides methods and apparatuses estimating casting throughput during casting process to provide polyamide pellets. The method of estimating casting throughput of an extruded polyamide polymer comprises measuring an amount of casting water flowing in to a casting apparatus typically from two or more locations, measuring the temperature of the casting water flowing in, and measuring the temperature of the casting water flowing out. Additional steps include calculating a heat transfer between the casting water flowing in and the casting water flowing out using the measured amount, and correlating the heat transfer to the casting throughput.

Abstract: The invention provides a continuous process for the production of 3-pentenenitrile, comprising: (a) contacting, in a reaction zone, a hydrogen cyanide-containing feed, a 1,3-butadiene-containing feed, and a catalyst precursor composition, wherein the catalyst precursor composition comprises a zero-valent nickel and at least one multidentate phosphorus-containing ligand selected from the group consisting of a phosphite, a phosphonite, a phosphinite, a phosphine, and a mixed phosphorus-containing ligand or a combination of such members; and (b) maintaining a residence time sufficient to convert about 95% or more of the hydrogen cyanide and to produce a reaction mixture comprising 3-pentenenitrile and 2-methyl-3-butenenitrile, wherein the 2-methyl-3-butenenitrile concentration is maintained below about 15 weight percent of the total mass of the reaction mixture.

Abstract: This document describes biochemical pathways for producing pimelic acid, 7-aminoheptanoic acid, 7-hydroxyheptanoic acid, heptamethylenediamine or 1,7-heptanediol by forming two terminal functional groups, comprised of carboxyl, amine or hydroxyl group, in a C7 aliphatic backbone substrate. These pathways, metabolic engineering and cultivation strategies described herein rely on the fatty acid synthesis pathway and oxidative cleavage of long chain acyl-[acp] intermediates by a monooxgenase (e.g., cytochrome P450) such as that encoded by BioI from microorganisms such as Bacillus subtillis.
