Fusible interlinings used on the coat mainly includes the front body, edges, parts and special parts; the coat fabric is mostly woolen or relatively high-end cotton and linen fabrics, so the front body lining of the coat is the main lining, mainly for shape. Therefore, the use of fusible interlining on the front body should fully consider the compatibility with the fabric; the side parts generally refer to the placket, neckline, cuffs, pockets, etc., using lighter and thinner non-woven fusible interlining.
