Abstract:

For effective selection of lining and substrate of composite material for clothing, luggages and bags, based on an overview of current research status of fabric formability at home and abroad, a new, easy and effective heading-ball method for evaluating fabric formability is proposed. This method evaluates the formability of the fabric according to the attached state of the sample fabric on the surface of the ball and the wrinkled degree of the sample. The results showed that the acting force and displacement curve recorded by the heading-ball method is closely related to the mechanical properties and formability of the fabric, that can be used to characterize the formability of fabrics. A large number of tests indicated that the method has good reproducibility and discrimination. The characterization method of fabric formability and factors influencing fabric formability are given. In order to effectively predict the fabric formability, this article uses finite element simulation software abaqus to simulate the headling-ball method. The acting force - displacement curves obtained are basically in aggreement with experimental values. This method provide a new thinking for the development of composite base cloth.
