The invention discloses a preparation technology of a fusible interlining special for silicon processing fabrics. The preparation technology sequentially comprises the following steps of base fabrics weaving, overflow loose type pretreatment, padding treatment, a first curing, fabric inputting, hot melt adhesive coating, a second curing, batching and final inspecting and packing. The preparation technology arranges base fabrics of the fusible interlining through an organic siloxane polymer solution, and applies polyurethane and polyesteramide system to conduct two points coating. After a product glues with silicon-based fabrics, the original smooth feel of the fabric is not influenced at all. Meanwhile, due to the plasticity of the polyurethane, a strike through phenomenon of the hot melt adhesive is avoided. The product is high in bonding strength, capable of resisting dry, washable and capable of being wildly applied in garment making of all kinds of smooth fabrics with silicon, and the problem of large tension of a surface when a lining cloth glues with the fabrics. The preparation technology also innovates in coating technology, and the hot melt adhesive on the surface of the lining cloth can be fast permeated and transferred on the fabrics when the lining cloth glues with the fabrics, so that the fabrics and the lining cloth can have a better adhesion.
