A nonwoven industrial fabric comprising a first layer secured to a second layer, with each layer comprising a plurality of flow-through apertures and profiling protrusions, wherein: a) at least a portion of the flow-through apertures of the first layer is aligned with at least a portion of the flow-through apertures of the second layer; b) the first layer comprises a plurality of securing protrusions integral to the first layer; c) the second layer comprises a plurality of detents integral to the second layer; and d) the first layer is secured to the second layer by a plurality of locking pairs, each locking pair comprising a securing protrusion lockably engaged with a detent. A method of making the nonwoven industrial fabric is also described.

Nonwoven double layer industrial textiles comprising a plurality of interconnected selectively slit and profiled folded panels formed from suitable sheet or film materials. Each panel includes two fold regions having an array of slots and seaming loops. The folded panel is formed by folding each fold region toward the panel body, thereby providing seam loops and seam loop receiving openings, which are used to connect adjacent folded panels in a given layer of the textile. Two such layers are bonded together in overlapping relation such that outside free edges of any of the fold regions are returned and sealed interior to the double layer. Further panels composed of heat or wear resistant material can be connected to lateral outside edges of panels forming the textile.

Non-woven double layer industrial textiles comprising a plurality of interconnected selectively slit and profiled panels formed from suitable sheet or film materials. Each panel includes two fold regions at each end. Each fold region has an array of slots and strips which form hem loops and hem loop-receiving openings by folding each region beneath and toward the panel body. The panel further includes two seam regions at a central portion of the panel, which when folded, provide seam loops and seam loop receiving openings. Outside free edges of the end fold regions are returned and sealed interior to the double layer so as to avoid fraying of free ends. Each seam region of the folded panel is interconnectable with the corresponding seam region of adjacent similar folded panels by means of a seam connecting member. Additional panels composed of heat- or wear-resistant material can be connected to lateral outside edges of panels forming the textile.
