Just before the beginning of WWII, American chemists developed synthetic polyamides. Polyamides are complex molecules called polymers, which are comprised of smaller “amide” monomers. In nature, these polyamide molecules occur as proteins in fibers, such as silk and wool. In the modern world, the best known polyamides are nylons. Because of their strength, elasticity and abrasion resistance, polyamide fibers are used in manufacturing durable apparel, such as jackets, swimwear and other sports garments.

Often
nylon textiles are coated to make the garment water-resistant. In decorating these fabrics with heat
transfer films, these coatings can also resist standard hot melt polyurethane
adhesives. To adhere to coated fabrics, the SEF FlexCut Sticky Nylon (a
polyurethane film for plotter cutting) and Tatoo Nylon (a printable
polyurethane film) are coated with a special polyamide hot melt adhesive, which
has an affinity for other polyamide materials. While you may have heard that
opposites attract, when it comes to adhesion, “like” materials usually build
stronger bonds.
Printing Tatoo Nylon
Tatoo
Nylon is printable using solvent, ecosolvent or latex inkjet printers. Before
laminating the applique with HotMask HM350, make sure that the print is
thoroughly dry. Otherwise you could smudge the image. While inks can dry in as little as fifteen
minutes to a half an hour, some prints will take longer. High humidity and
other ambient shop conditions could prolong the drying process.
To
heat press FlexCut Sticky Nylon or Tatoo Nylon to a garment, set the
temperature at 240⁰ F (115⁰ C).
After
the printed Tatoo Nylon has dried, squeegee HM350 to the applique using good
pressure. Remember that the adhesive on HM350 is a pressure sensitive and it
takes pressure to promote adhesion. After laminating the transfer tape, allow
20 to 30 minutes before use.
To
heat press FlexCut Sticky Nylon or Tatoo Nylon to a garment, set the
temperature at 240⁰ F (115⁰ C). After pressing the
applique for 17 seconds at medium/high pressure, remove the HM350, after a
couple of seconds, while the garment is still warm.
After
pressing the applique remove the HotMask, while the garment is still warm.

applications refer to the Heat Transfer Films Product Application Chart.
