A composite electrochromic material, a preparation method therefor and an application thereof, the material comprising a core layer, a skin layer having an electrochromic function, and a light-transmitting protective layer formed by a flexible polymer material, that are arranged in sequence. The material of the core layer comprises a fluid conductive mixture, which comprises liquid metal and carboxylated carbon nanotubes. The preparation method comprises: carrying out spinning by co-extrusion using a three-channel nozzle to form hollow double-layer fibers each having a skin layer and a protective layer as well as a cavity, injecting the conductive mixture into the cavity of the hollow double-layer fiber. The material has excellent deformation ability, stable and sensitive color changing function, and a controllable deformation degree. The material has a stable color changing function even in the case of severe defomation, good fatigue resistance, and is suitable for the preparation of intelligent textiles.

A protective drainage wrap comprises a cross-woven material portion, cross-laminate material portion or mesh material portion in first and second directions and a breathable solid layer portion. The material in the first and second directions comprises a polyolefin, polyester, nylon or combinations thereof. The first direction being roughly perpendicular to the second direction. The cross-woven, cross-laminate or mesh material portions being adapted to facilitate a drainage path. The breathable solid layer portion is attached to the cross-woven material portion, cross-laminate material portion or mesh material portion. The breathable solid layer portion is adapted to allow water vapor to flow therethrough.

A belt for an elevator system and a method for making the same is provided. The belt includes a plurality of tension members that extend along a length of the belt and a jacket. The jacket substantially retains the plurality of tension members. The jacket maintains a desired spacing and alignment of the tension members relative to each other. The jacket includes a plurality of first fibers and a plurality of second fibers. The jacket defines at least one exterior, traction surface of the belt. The first fibers are at least partially disposed between the tension members and the traction surface of the belt. The second fibers are fill fibers. The first fibers have at least one property that distinguishes them from the second fibers.

A sheet material with an anti-skid surface, suitable for use as a roofing underlayment or wrapper, comprises a scrim made of woven plastic tapes with monofilaments that are round in cross-section and have a diameter larger than the thickness of the plastic tapes interwoven with the tapes. The monofilaments form ridges on the sheet material that impart an enhanced coefficient of friction to it. The monofilaments may be incorporated in the weave in the warp or weft directions or both.

Disclosed are interfacially modified particulate and polymer composite material for use in injection molding processes, such as metal injection molding and additive process such as 3D printing. The composite material is uniquely adapted for powder metallurgy processes. Improved products are provided under process conditions through surface modified powders that are produced by extrusion, injection molding, additive processes such as 3D printing, Press and Sinter, or rapid prototyping.
