A three part series of articles on the compatibility of outer and fusible interlining fabrics focuses on the development of an objective method of selecting compatible fusible interlinings for different outer fabrics to achieve superior apparel fabric hand and drape in tailored apparel. Part One establishes the desirable range of mechanical properties of fused composites for the front parts of tailored jackets, excluding the lapels and collars. Researchers proposed a control chart for the objective evaluation of the mechanical properties of the fused composites for compatibility with outer fabrics. Part Two will examine the relationship between the mechanical properties of the fused composites and their constitutent fabrics and fusible interlinings. Part Three will propose a method of selecting compatible fusible interlinings based on FAST fabric objective measurement results. 4 refs.
