Provided is a spiral membrane element that has a restricted outer diameter and is capable of being decreased in operation energy therefor. The element is a spiral membrane element including plural membrane leaves in each of which a permeation-side flow-channel member is interposed between opposed separation membranes; a supply-side flow-channel member interposed between any two of the membrane leaves; a perforated central pipe on which the membrane leaves and the supply-side flow-channel member are wound; and a sealing part that prevents a supply-side flow-channel member from being mixed with a permeation-side flow-channel member. This element has an efficiency index E of 0.005 to 0.10, the index being calculated in accordance with an expression described below, and the thickness of the supply-side flow-channel member is from 10 to 110 mil. Efficiency index: E=0.0024X0.2373+(Y/(D.sup.2L)) wherein X is a thickness [mil] of the supply-side flow-channel member, Y is an effective membrane area [ft.sup.2] of the separation membranes, D is an outer diameter [inch] of the membrane element, and L is a length [inch] of the membrane element.

Advances in actuating fabrics could enable a paradigm shift in the field of smart wearables by dynamically fitting themselves to the unique topography of the human body. Active fabrics and fitting mechanisms are described herein that enable garments to conform around surface concavities without requiring high elasticity or a multiplicity of closure devices. Advanced materials and systems innovations (1) enable novel garment manufacturing and application strategies, (2) facilitate topographical fitting (spatial actuation) through garment architectural design, and (3) provide tunable NiTi-based SMA actuation temperatures to enable actuation on the surface of human skin. Such fabrics and garments are usable in a variety of fields including medical compression, technical sportswear, exosuits, space suits and components thereof, or non-garment applications.

A spiral membrane element is provided which has a restricted outer diameter but is heightened in effective membrane area, and further which can be decreased in operation energy therefor. The spiral membrane element is an element including plural membrane leaves L in each of which a permeation-side flow-channel member 3 is interposed between opposed separation membranes 1; a supply-side flow-channel member 2 interposed between any two of the membrane leaves L; a perforated central pipe 5 on which the membrane leaves L and the supply-side flow-channel member 2 are wound; and sealing parts that prevent a supply-side flow-channel from being mixed with a permeation-side flow-channel. The sealing parts include both-end sealing parts 11 in which an adhesive is used to seal two-side end parts of each of the membrane leaves L on both sides of the leaf in an axial direction A1 of the leaf. The thickness T1 of the both-end sealing parts 11 is 390 to 540 m.

A knitted textile includes a textile electrode region, a conductive trace region that terminates in a knitted extension, conductive material, located at an intersection of an ablated area and the textile electrode region, configured to provide an electrical connection between the conductive trace region and the textile electrode region, sealing film, placed around the conductive material, configured to protect the conductive material and seal the conductive material from one or more textile layers that surround the electrical connection, and an outer sealing patch surrounding the textile electrode region and configured to provide a moisture barrier between the textile electrode region and the one or more surrounding textile layers. The conductive trace region includes one or more electrical conductors twisted with an insulator. The knitted extension is configured to overlay a portion of the textile electrode region and includes the ablated area where the insulator has been removed.
