Manufacturing Process
Hot Melt Adhesive Film on Sockliner

The compositions of regular sockliner or moulded sockliner are fleece or terry toweling laminating EVA foam with solvent-based adhesive and cutting in the form of sockliner or through hot compress and fixation to become moulded sockliner. The shortcoming of this process is the residues of toluene or VOC. So we use hot melt adhesive film instead of solvent-based adhesive to eliminate the residues of VOC and shorten the process.

1.         Regular sockliner

a.             Laminate hot melt adhesive film on the fleece or directly coating hot melt adhesive film on the fleece.

b.             Use general hot press laminator. Hot press fleece and EVA foam.

c.              After laminating, cut into the form of regular sockliner.

2.    Moulded sockliner(Hot compress and fixation)

I.      Cold model

a.         Laminate hot melt adhesive film on the fleece or directly coating hot melt adhesive film on the fleece.

b.         Fleece and EVA foam passing through the heating oven at the same time. When the two come out of oven, directly send into the cold model to compress and fixation.

c.         After finalized, trim the excess material.

II.    Hot model

a.         Laminate hot melt adhesive film on the fleece or directly coating hot melt adhesive film on the fleece.

b.         Lay the fleece on EVA foam and then compress in the hot model then cooling down to fixation.

c.         After finalized, trim the excess material.
