Hot Fix Water Drop Test
When applying Hot Fix stones or other Hot Fix trim items, the optimum bond can only be achieved if the carrier material can absorb the glue. A simple water drop test will indicate whether or not the fabric has this attribute. If the fabric has e.g. a waterproofing finish, it will not absorb drops of water or glue.
With textiles that contain a large quantity of softening agents, adhesion can be improved by washing the original materials before the application process.
Very fine fabrics such as organza, as well as smooth leather, smooth leather imitations, tightly woven polyamides and fabrics with a silicone or wax finish may not be suitable for Hotfix application due to insufficient absorbency.
