Natural fibres can again be divided into two types based on their source i.e. The tensile strength can be described as the measure of the maximum resistance of longitudinal stress before it breaks. All fabrics can be characterized as either natural or synthetic fibers (or a blend of the two). Fibres used to make fabric may be natural or synthetic. Leaf fiber: Fibers collected from leaves. 6.
