摘要:
A multi-layer ballistic woven fabric, including an upper woven layer having upper warp yarns and upper weft yarns that are interwoven together to form the upper woven layer. The multi-layer ballistic woven fabric also includes a lower woven layer having lower warp yarns and lower weft yarns that are interwoven together, and a plurality of securing yarns, each securing yarn interwoven with at least some of the upper yarns and some of the lower yarns so as to secure the upper and lower woven layers together. At least one of the securing yarns is woven underneath a first lower weft yarn, then above a second upper weft yarn adjacent the first lower weft yarn, then underneath a third lower weft yarn adjacent the second upper weft yarn and then above a fourth upper weft yarn adjacent the third lower weft yarn. The multi-layer ballistic woven fabric is formed by interweaving the securing yarns with the warp yarns and weft yarns as the upper woven layer and lower woven layer are made.
摘要:
A shockpad comprising a three-dimensional entangled mat of extruded filaments made from a thermoplastic elastomeric polymer, especially a thermoplastic elastomeric polyester polymer or a thermoplastic elastomeric polyurethane polymer, provides improved shock absorption and energy restitution in artificial turf systems.
摘要:
A sheet material that includes an elastic component or material (e.g., film, nonwoven web laminated to the elastic component, etc.) is provided. The elastic component is formed from a styrenic block copolymer composition containing from about 10 wt. % to about 90 wt. % of styrene-butadiene-styrene block copolymer; and from about 10 wt % to about 90 wt. % of styrene-isoprene/butadiene-styrene block copolymer. The styrenic block copolymer composition has good viscosity stability during extrusion and thus may be readily formed into an elastic sheet material. The elastic sheet material may be subsequently crosslinked to achieve the desired elastic and mechanical properties.
摘要:
The disclosure is directed generally to stretchable articles and/or assemblies, more specifically stretchable knitted articles and/or assemblies having at least one elastomeric adhesive and a method for making the same. One aspect of the disclosure is an lastomeric textile product comprising a textile design and a self-supporting, elastomeric adhesive layer. In one preferred embodiment, the self-supporting, elastomeric adhesive layer comprises an elastomeric film position between opposing first and second adhesive films.
