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, three
meters, and four 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.
