Woven fusible interlining has a proper woven structure — yarns interlaced in both directions — making it stronger, more durable and better at retaining structural shape. It is used for the full-front body of suits, blazers and sherwanis (80–150 GSM). Non-woven fusible interlining is made by bonding fibres together — lighter (30–82 GSM), more economical, and suited for collars, cuffs, plackets and smaller garment parts where full structural support is not required. Most factories use both: woven for the garment body, non-woven for construction details.
