摘要:
A method for the production of a conductive flexible textile array. The method includes the application of an oxidizing agent to selected areas of the textile; coating the textile with pyrrole by vapor deposition to form a conductive coated textile having a polypyrrole network; stabilizing the conductive coated textile; and forming the conductive flexible textile arrays as a sensor. With this method of production, the degree of polymerization of the conjugated polymer, the morphology and the rate of the capacitance delay is carefully controlled. As such, stable flexible textile sensors are produced with various levels of sensitivities and conductivities which are particularly useful for designed applications.

This invention relates to patterned conductive textile sensors such as those for simultaneously measurement of strain, temperature and relative humidity. The patterned textile structures comprise sensing elements of various electrical conductivity and they are in the forms of fabrics, fibres, filaments or yarns coated with conductive polymers.

A method of making a photonic fabric display includes wrapping photonic fibers with a yarn, weaving the wrapped photonic fibers to form a fabric, printing a pattern on the fabric, surface treating the fabric, and coupling the photonic fibers with a light source to form a photonic fabric display.

A process for measuring snarling properties of a yarn is provided. Firstly a first and a second point of the yarn are held in close proximity, and a portion of the yarn between the two points is of a predetermined length. A predetermined tension force is temporarily exerted to the portion of the yarn, and simultaneously the portion of the yarn is temporarily restricted from twisting when the tension force is exerted. Then the portion of the yarn is released from the tension force such that the portion of the yarn is able to twist freely so as to form snarls thereon. Thereafter, the snarling properties of the yarn are measured by detecting an amount of the snarls thereby formed.

A three-dimensional cellular textile composite structure with energy-absorbing capacities under multiple impacts is provided. The cellular textile composite structure includes a base, and at least one progressively collapsible projection extending from the base for absorbing energies under the multiple impacts. The projection includes a non-woven textile material supported in a thermoplastic matrix material such that the projection is capable of retaining energy-absorption capacity at least after the first impact of the multiple impacts.
摘要:
A yarn is spun by dividing a traveling fiber assembly into a plurality of fiber sub-assemblies, causing the sub-assemblies to traverse different paths and then recombining them, wherein the paths are sufficiently proximate for fibers to continuously transfer from one or more of the sub-assemblies and be drawn onto or into another or other sub-assemblies. Also disclosed is a method for forming a yarn comprising twisting a plurality of fiber sub-assemblies together at a convergence point to form a fiber assembly being a yarn, and further including cyclically altering the relative twist propagation in and/or into the sub-assemblies upstream of the convergence point. Still further disclosed are alternative methods involving cyclic variation of paths traversed by the sub-assemblies, and cyclic alteration of the relative positions of the sub-assemblies. Apparatus is described for carrying out each method.
