Fusing is an adhesive material with a variety of functions that you can use as an alternative to sewing. In this process cut components or separate parts of a lay (blocks of components) are fused with interlinings that are coated with thermoplastic resin. The material is available in woven or non-woven sheets, shapes and strips. Fusing often serves as alternative to sew-on interfacing, which strengthens, supports, adds shape to fabric and crease resistance of a garment.
Quality Control in Fusing:
To control the quality of fusing, selection of interlining and conditions of fusing are very important. The factors affecting the quality of fusing are discussed below:
A. Fusing temperature
Optimum fusing temperature is recommended by the interlining supplier. During fusing, if this temperature is not maintained properly then the fusing performance may degrade. Over temperature will produce strike through or strike back and under temperature will produce insufficient bond strength. The fusing machine showing fusing temperature needs to be checked time to time. To check the fusing temperature, Pyrometer or Thermo paper may be used. In Pyrometer, there are probes which to be set inside the interlining and fabric. Then fusing is done. If the temperature, showing by both Pyrometer and fusing machine, is same then the machine showing temperature is assumed to be correct. But if differs, and then is necessary to confirm which one is giving accurate result. Under such situation, Pyrometer is checked by hot water of known temperature. Thermo paper is a kind of scaled paper which is temperature sensitive. Due to effect of temperature color of the thermo paper is changed and shows the temperature.
B. Fusing pressure
Fusing pressure is to be maintained as per recommendation. If recommended pressure is not maintained then strike through, strike back or insufficient bond strength may result. Hence fusing pressure shown in the dial of the machine needs to be checked time to time. To check the fusing pressure paper strip and pressure pill may be used. The pressure pill is placed inside the fusing bed during fusing. Due to fusing pressure the dimension of the pressure pill is changed. Increased dimension of pressure pill is assessed with the reference chart and fusing pressure is determined. If the reading of chart and reading of machine differ, then the machine showing pressure is defective and needs to be controlled.
C. Fusing time
Fusing time showing in the machine is to be checked time to time with the aid of a stop watch.
D. Pilling strength
The bonding strength of fused components is to be checked by a tensile strength tester and compared with the recommended pilling strength.
E. Washing or Dry cleaning
Due to washing and dry cleaning, appearance of the fused components should be unaffected. If it is not maintained after washing or dry cleaning, then the performance of the interlining will be unsatisfactory.
