These fibers are mechanically interlocked by punching needles through the layer of fibers. In this process parts of the fibers are drawn to the bottom and other fiber parts are drawn to the top creating an extremely strong three (3) dimensional fabric with exceptional tensile strength and resistance to puncture and tears.
Nonwoven fabric typically have a high strength to elongation ratio which produces a large area, when charted, under a curve known as toughness. While non-wovens do not have the same initial strength as wovens they will stretch to accommodate a load returning to there original orientation once the load is removed. Non-wovens will allow the lateral drainage of water through the plane of the fabric (3-D) providing better soil filtration properties.
YARD-TEK WOVEN
Yard Tek Woven Fabrics are made from a 'continuous sheet of polypropylene film' that is slit into yarns. In general, weaving involves taking the 'slit film yarn' and interlacing them at right angles to each other.
Woven landscape fabrics have a high percent open area which is distinct, uniform and measurable openings in the fabric. This EOA assures that both water and soil particles have a direct path through the fabric. To reduce the open area of these woven fabric, a top layer of fiber in sometimes needled into the fabric to increase opacity, blocking more light while continuing to provide exceptional strength.
