Geotextiles (Erosion Control Blankets) Loosely spun coir yarns are woven to make a coir blanket. The type of coir used in the blanket is brown mattress coir. Mattress fibre contains light-weight, thin fibers. The coir yarns in the blanket are extremely flexible. These yarns are lower in tensile strength compared to the tightly spun yarns. Loosely spun mattress coir yarns have a puffy texture. When used in a woven blanket, puffy yarns increases the ground cover and hold extra moisture. Flexible yarns increase the flexibility of the blanket. The high flexibility of the blanket increases the blanket's ability to conform to the contour of the soil surface. As a result, upon installation the woven coir blanket hugs the soil surface and holds soil particles in place. The woven coir blanket has higher wet tensile strength and functional longevity (3-4 years) than many other organic ECBs. Mattress coir woven blankets come in widths of two meters. The available wide widths of the blanket reduce installation labor and save materials due to fewer overlaps. The one hundred percent coconut fiber blanket eliminates problems associated with organic ECBs with either polypropylene or jute nets.
