Many garments are manufactured using an interliner to give stiffness to the product. Perhaps the best examples are the lapels of blouses and shirts. The construction of a typical shirt collar is a layer of cotton, a layer of heat sensitive non woven resin impregnated interliner, and a layer of cotton. This sandwich is then subjected to controlled heat and pressure, the interliner melts and fuses to the two layers of cotton, and after cooling the resultant fabrication has added stiffness. | ![]() |
In industry, the sandwich is placed on a moving belt and is carried over a heater bank. A second belt running in the same direction is then placed on top of the sandwich, which is then carried between a pair of driving rollers acting like a calender.
By controlling the nip pressure and heating cycle, the resin impregnated interliner can be brought to the required plasticised condition that gives the best fusion results. Some resin can escape and to ensure that the belt surface is kept in precise condition; non stick, conductive PTFE glass belts are used universally for this application.
![]() | With delicate fashion fabrics a top quality 0.25 mm (0.010 inch) thick conductive GORTEF 828.25AS must be recommended, however, with heavier materials and garments such as waist bands, suits and overcoats, GORTEF 141.36 AS should be used.

There are many machine manufacturers in Europe. The largest machines, with belts 9.2m x 1.9m are very specialised and tend to be serviced by the OEM. However, there are many machines from Europe and Japan that use smaller PTFE glass bets and where end users are buying directly from belt manufacturers.
