Flat knitting allows production of textile structures (e.g., for use in footwear uppers) of a final desired shape such that textile cutting steps can be avoided. Flat knitted elements also can be formed directly in desired three dimensional shapes, which can help avoid the need to use additional support structures (e.g., in footwear construction). By selectively placing multiple different yarns and / or stitch patterns at multiple different locations in the overall structure during the knitting process, flat knitted products may have multiple different physical properties (e.g., different stretchability, different moisture management capabilities, etc.) at multiple different locations or zones within a single, unitary construction (e.g., different properties at different zones or locations within a single footwear structure). Additionally, flat knitting can be used to produce pockets, tunnels, or other layered structures in the final product.

A detection and monitoring method and system which makes it possible to detect the presence of moisture problems when they manifest as abnormal humidity in one or more discrete ventilation zones within a building envelope.

The present invention provides an early warning system that will alert personnel of the occurrence of a moisture problem.

A composite textile fabric for rapidly moving moisture away from the skin, and for retaining body heat, is provided. The composite fabric includes an inner fabric layer made of a yarn comprising a plurality of fibers primarily of polyester or other synthetic yarns which have been rendered hydrophilic, and an outer fabric layer made of a yarn comprising a plurality of fibers primarily of polyester or other synthetic yarns which have also been rendered hydrophilic.
