Terminology
Fabric – A woven or laid cloth made of yarns.
Fabric Clamp – Device for clamping the edge of a fabric panel, usually a bar or channel shape and made of aluminum or steel.
Light Transmission – A measure of the portion of light striking a fabric surface that passes through the fabric and into the space to provide daylighting.
Mast – The principal upright in a tension structure. Membrane – The fabric panels used in tension structures.
Membrane Plate – Metal plates attached to the membrane corners used for securing the membrane to the frame.
Node Points – Intersection points of the elements used to define the fabric shape in the structural analysis; these are normally given in terms of a three-dimensional coordinate system.
Patterning – The process of defining two-dimensional pieces of fabric, which can be spiced together to form a desired three-dimensional shape.
PTFE - “Polytetrafluoroethylene”, commonly known by its trademark name Teflon™. This coating is applied to a fiberglass scrim to produce a high strength tension structure fabric membrane with a life expectancy of thirty plus years. PTFE may also be expanded and woven into a fabric that can be coated with a fluoropolymer to create a high strength architectural fabric.
PVC - “Polyvinyl chloride”, properly mixed with plasticizers for flexibility and applied to a polyester scrim makes for a high strength and popular tension structure fabric membrane. The life expectancy and cost are proportionally lower than PTFE.
Top Finish (AKA "Topping") – An additional coating sometimes used on fabric for greater protection against UV degradation or for ease of cleaning purposes (i.e. Ferrari’s PVDF named “T2®”; or Dupont’s PVF named “Tedlar®”).
Turnbuckle – Threaded device used with cables or rods to allow adjustment.
Ultraviolet (UV) Degradation – The deterioration of a fabric under long-term exposure to sunlight. Using a top finish on the fabric will help prevent the UV degradation.
Warp Yarn – The long straight yarns in the long direction of a piece of fabric.
Weaving – The process of making a fabric from yarns passing alternately over and under each other.
Weft Yarn – The shorter yarns of a fabric, which usually run at right angles to the warp yarns. Also called the fill yarns.
Weldment – Connection component, usually steel, for the attachment of cables and/or fabric. If may be free-floating or connected to other membranes.
Wicking – The conveying of liquid by capillary action along and through the yarns of the base fabric.
Wrinkles – Furrows or ridges on the normally smooth surface of a fabric structure, which are indicative of extreme differences between the principal stresses typically resulting from a lower stress perpendicular to the furrow.
