Quality control in fusing or point should be considered before fusing

Factors on which the quality of fusible interlining depends-

Temperature: Fusing temperature depends on types of fusing interlining. For particular interlining the definite temperature is set in the control panel of the fusing temperature can be read from machine dial during fusing.

Pressure: The pressure should be uniform and sufficient over the whole fusing bed and rollers during fusing. Pressure pill may be used to check the amount of pressure. These pills are placed in the shortest interval across the fusing bed width and the variation in volume of these pills is observed to know the uniformity of pressure.

Fusing time: The equipment must give enough time to allow the temperature and pressure to induce melting of the resin and penetration of the outer fabric in order to produce a satisfactory bond. Coarser fabric requires more time, but fabric requires less time. To check time of fusing, a stopwatch is used.

Pilling strength: the bond strength between the fabric and interlining due to melting resin is checked to measure the fusing efficiency.

Dry cleaning or washing: The check again after washing or dry cleaning with water or fused parts. Specially to check the changing bond strength or dry cleaning.
