Characterization of the Physical Properties of the Coconut Fiber Residue With a View to its Agroindustrial Use

Abstract

Abstract Ecuador is a multi-climatic country with the capacity to host a large number of plant species; one example is the coconut (Cocos nucifera), an ancestral food of tropical areas and warm climates, which is considered as raw material for various industrial processes, such as obtaining fats, oils, candies, etc. However, the external part of the coconut constituted by the bast or mesocarp has not been properly exploited. Coconut bast, which has high fiber content (coir fiber), from which three main types can be distinguished: long and thin, coarse, and shorter type, can become an agroindustrial alternative due to its mechanical properties. These properties are as good or better than synthetic fibers or polyester. This research therefore aims to characterize the physical parameters that determine the functionality of coconut fiber, such as its length, softness, brightness, color, diameter, and its appearance or slenderness, which is the relationship between length and diameter. This research also contributes to solving the environmental problem of waste generated by coconut production, moving towards a sustainable economy from an environmental point of view. This work determines that coconut fiber is composed of cellulose and wood that has low heat conductivity and impact resistance, and that its resistance and durability make it an adequate raw material in several production sectors.
