A fusing machine permanently bonds a base fabric with a fusible interlining (buckram or resin-coated lining) using a controlled combination of heat, pressure, and dwell time. This process reinforces structural integrity, stabilizes edges, and ensures consistent garment drape without bubbling or delamination.
Core Functions & Working Mechanism
A fusing machine executes three synchronized variables to melt and embed the thermoplastic resin (polyethylene, polyamide, or polyester) into the yarn interstices of the face fabric:
Controlled Heating: Top and bottom heating elements heat the assembly to the exact melting point of the resin (typically 120°C to 175°C), ensuring the resin liquefies without scorching sensitive face textiles.
Calibrated Pressure: Rollers (pneumatic, spring-loaded, or hydraulic) apply uniform mechanical force across the entire width (typically 1.5 to 5.0 kg/cm² or bar) to force molten resin into the fabric weave.
Regulated Dwell Time: Speed-controlled conveyor systems ensure the fabric remains in the heating zone for an exact duration (generally 8 to 20 seconds) before passing through cooling zones to solidify the bond.
