Patent number: 11608590Abstract: Compositions especially suitable for forming fibers and films having good elasticity and relatively high modulus are disclosed. Surprisingly, compositions including a styrenic block copolymer having a relatively high melt flow rate, and a detackifier, and optionally, but preferably in some embodiments a polyolefin (co)polymer, and/or polystyrene polymer, and/or a softener have good draw down performance and are processable into fibers having low tack, relatively high modulus and tensile strength. The fibers produced from the composition can be processed easily and are useful to manufacture articles such as fabrics, both woven and non-woven, webs, threads, and yarns. In various embodiments, unique fiber structures are produced having low tack and desirable elasticity.Type: GrantFiled: February 17, 2017Date of Patent: March 21, 2023Assignee: TEKNOR APEX COMPANYInventors: Kushal Bahl, Darnell C.

Patent number: 9863565Abstract: An expandable hose assembly that is able to expand one or more of longitudinally along the length-wise axis of the hose between hose ends and radially, to an expanded state in response to application of at least a minimum fluid pressure to an inner tube of the hose. Once the fluid pressure falls below the minimum fluid pressure, the hose will contract. The hose includes a thermoplastic elastomer inner layer and a slip coating layer thereon having lubricating properties that increases the life of the hose assembly. The hose assembly can include an outer sheath or covering that covers the inner tube and slip coating layer.Type: GrantFiled: November 18, 2015Date of Patent: January 9, 2018Assignee: TEKNOR APEX COMPANYInventors: Chris LaTulippe, Kevin Cai, Ron Eilertson, Timothy L.
