Guidance for Fusing Tests

How to make it correct

Why Fusing Tests ?

Today's fabric and interlining is very sensitive to heat and pressure. If the fusing machine is not in a good condition or fusing conditions are not according to the interlining specification, a lot of problems can be created.

Fusing was and  still is a very delicate operation within the garment manufacturing process. If any problem arises, it has to be eliminated immediately, as problems easily can be multiplied.

The Test Set is made to assist you in checking your fusing machine and fusing goods by clear results.

It was made for day to day use on the production floor in cooperation with most of the major interlining suppliers.

Beside the fusing test itself, the test result has to be noted in a report and should be stored for later use or as proof of correct fusing.

The documentation should show the following details:

1.  Set temperature, top heat zone
2.  Set temperature, bottom heat zone
3.  Glue line temperature
4.  Set pressure (for one or two pressure systems)
5.  Set speed (in seconds)
6.  Bond strength after fusing, in Newton
7.  Shrinkage after fusing, in Percentage
8. Any special characteristic of the shell fabric and/or  interlining.
9. Any change of characteristic after fusing, like shading effects, discolouration, flatness etc.
10.  Stick a sample of the shell fabric and the interlining to the data sheet.

For further tests, like washing or dry cleaning tests use the following form sheet as a reference.
