| Abstract/Contents: | "Coconut fiber (coir) is an abundant natural fiber resource that has drawn the attention of the erosion and sedimentation control industry recently. Use of coir products for erosion and sedimentation control is increasing. Applications of bioengineering techniques in erosion and sedimentation control are getting popular, so is the use of coir products. In the categories of durability and wet strength, coir can be rated as the number one raw material among all types of organic materials used in the industry. With increasing use of coir in erosion control products, there is a need to educate designers and end users of products about various grades of coir and their effects on quality and performance. Traditional way of processing coir begins with curing the coconut husks in fresh water for 6-12 months. Curing of husks increases the durability of processed coir. The cured husks are machine processed for coir. During processing, the initially seperated fiber is called mattress fiber coir. This coir is very short, thin, and flimsy. The next type of coir separated from the husk is called omat fiber coir. Omat fibers are fairly long and strong. Once the mattress fiber coir and omat fiber coir are seperated, the remaining coir is called bristle fiber coir. Bristle fiber coir is longer, thicker, and stronger compared to the other two types. The bristle fiber coir has the highest resistance to rotting and the highest strength, compared to the other two coir types. Coir processed from partially cured coconut husks has low durability. This variability in properties of different coir types lead to variations in performance in the final products. For example, woven coir blanket made of bristle fiber coir will deliver much superior performance compared to a woven coir blanket made of any other coir. This paper discusses two widely used coir erosion control products (coir polypropylene netted blankets and woven coir blankets) and their performance and properties related to type of coir used in the blankets. This paper compares the tested physical properties of three types of woven coir blankets available in the market. Finally, the paper discusses several characteristics of coir blankets that need to be considered when specifying the product which will help designers and end users to identify the correct product for their needs." |
