Abstract: Disclosed are fibers comprising a modified polyamide, such as a modified nylon-6, a modified nylon-6,6, or a modified nylon-5,6. The polyamide may be modified to contain a modified polyolefin, such as a maleated polyolefin. The disclosed fibers are hydrophobic and have surprising properties and benefits as compared to fibers having the same base polymer but without modification.

Abstract: This document describes biochemical pathways for producing a difunctional product having an odd number of carbon atoms in vitro or in a recombinant host, or salts or derivatives thereof, by forming two terminal functional groups selected from carboxyl, amine, formyl, and hydroxyl groups in an aliphatic carbon chain backbone having an odd number of carbon atoms synthesized from (i) acetyl-CoA and propanedioyl-CoA via one or more cycles of methyl ester shielded carbon chain elongation or (ii) propanedioyl-[acp] via one or more cycles of methyl ester shielded carbon chain elongation. The biochemical pathways and metabolic engineering and cultivation strategies described herein rely on enzymes or homologs accepting methyl ester shielded aliphatic carbon chain backbones and maintaining the methyl ester shield for at least one further enzymatic step following one or more cycles of methyl ester shielded carbon chain elongation.

Abstract: A method for producing a woven fabric comprises weaving fibers in a warp direction and a weft direction to form a fabric having a top surface and a bottom surface, wherein the warp fibers and weft fibers each comprises one or more filaments of a synthetic polymer having substantially uniform cross-sectional composition. At least a portion of the filaments in the fibers on the top and/or bottom surface of the fabric are then fused together in the presence of a heat transfer liquid or vapor added during the fusing step or added in a prior step of the fabric production process and retained by the filaments. The fusing step produces a treated fabric having a tensile strength in both the warp and weft directions of 1000 N or greater and having, in the absence of any coating, a static air permeability (SAP) of 3 l/dm2/min or lower.
