Test in advance is necessary to check bonding strength hand feeling, color shade, heat shrinkage and appearance etc because fusing terms can vary depending on shell-fabric and fusing machine.

 §   Fusing temperature must be actual temperature affected to the coated hot melt adhesives between shell-fabric and interlining.
 §   For pilled shell-fabric such as corduroy, velveteen and etc, two-ply work facing pile  to pile with lower pressure is recommended and test of washing is strongly required.

o   When testing:
 § Should be careful to prevent from strike through of powder and moire problem for the thin fabrics.
 § In order to prevent from heat shrinkage of shell fabric and to get stable and high quality products, it is recommended to make fusing temperature lowest and fusing time longest ( 13sec-21 sec) as for as possible.
 § Should always keep the pressing machine clean

o  Fusing Machine:
In case of continuous input of shell fabric + interlining to roller press machine, bonding strength can become weaker from the first out put to latter out put, so frequent check of temperature is required and specially for all wool fabric, one-ply work with
longer fusing time is recommended.
