Abstract: The invention relates to a fabric used for preparing a base member of a trim member. This fabric is prepared by heating a mixture of a vegetable stiff fiber and a thermoplastic fiber. With this heating, the thermoplastic fiber becomes soft, and thus the vegetable stiff fiber and the thermoplastic fiber are united together. Examples of the vegetable stiff fiber are hemp fiber, coconut fiber and bamboo fiber. An example of the thermoplastic fiber is a composite fiber made of polyethylene and polypropylene. The fabric is superior in strength and workability and becomes advantageously low in heating temperature for molding the fabric.
