NX6865 Fiber Mat highly effective first-down clear underbase that wets and holds down fibers on garments prone to fibrillation. It also provides an extremely smooth surface that enhances the appearance of overprint colours. While a single print is sufficient to hold down the fibers on most garments, a print/flash/print technique may be needed on garments made from recycled materials or extremely fuzzy fibers.
Mesh—Mesh sizes between 83T and 110T (32-43/inch metric) are recommended. Fabrics known to be bad fibrillators should be printed with the lower mesh count and a print/flash/print technique used to print the underbase.
Squeegee—For best results use 70 durometer or 70/90/70 triple durometer squeegees.
Gel Temperature— Inks will gel when surface temperature reaches 220°-240° F (104°-116° C). Because Fiber-Mat flashes slightly slower than regular Evolution NX inks a longer dwell and more heat may be necessary to surface gel the underbase and to activate the component that holds down the fiber.
Curing— When printing on 100% cotton fabrics Fiber Mat fully cures when the entire ink film reaches 310°-320° F (155°-160° C) for 45 seconds to 1 minute inside the dryer. Fiber Mat is not high-opacity or bleed-resistant. When printing 100% cotton dark garments it will be necessary to overprint Fiber Mat with NX6581 Optical White before printing colours to insure colour accuracy and opacity. On n dark-coloured 50/50 cotton/poly blends or 100% polyester fabrics opacity bleed resistance may be controlled by lowering dryer temperature to 275° Fahrenheit (135°-137° Celsius) for two minutes inside dryer chamber. However, if printed on dark-coloured 50/50 cotton/poly blends or 100% polyester fabrics known for dye migration colours should be underbased with the appropriate Evolution Defender dye blocker and NX6581 Optical White.
Reducer—Do not add Viscosity Reducer NX6390 (1-3% maximum) until viscosity is evaluated after thoroughly stirring the ink.
Ink Cleanup—Use Enviro Series 2000 Green or Enviro Series TR Blend.
Storage—Ink should be stored at temperatures less than 30°C/84°F. Extended storage in warmer conditions can cause inks to thicken.
Always test finished prints for color accuracy, curing, adhesion, opacity, crocking, stretch and desired look prior to beginning full production runs. Lancer Group International cannot guarantee the results or back claims that this ink will test PVC-free or phthalate-free if any pigment or additive other than an Evolution Pigment Concentrate or Evolution NX System additive that has been manufactured by Lancer Group International is used in this ink. Contamination can also occur from mixing tools, mixing buckets, spatulas, squeegees, or flood bars that have had prior contact with inks containing PVC’s or phthalates and these tools must be thoroughly cleaned before using with the NX System.
