1 Gallon of Polyester Pretreatment for White and Dark Polyester Blend Shirts
Poly PreTreatment is specially formulated to help work with textile ink and polyester and poly-blend fabrics, printing White and CMYK.
Understand that successful Polyester and Poly Blend printing is just as much about curing as it is about the ink and pretreatment. This Pretreatment is NOT the only ingredient that will make polyester and poly blend printing work. I can't stress this enough. You need to play with cure and hover times. Please read below to get a better understanding.
CURE TIME - varies between different poly blends and how much pretreatment you apply. However, 300° with a 30 sec hover or some variation of that will work. Depending on the polyester blend you are using you need to be careful not to scorch the shirt. Using a infrared Dryerworks best, however hovering on a heat press works also. Some poly blends you can get away with using light pressure.
*You have to do some wash testing on all printed poly and poly blend garments prior to selling because the blend and composition of different brands vary which means results could vary
This is an example of how a dark polyester shirt printed without out poly pretreatment and then after with poly pretreatment
Have used the Poly Pretreat on a dozen different pieces now and it does a great job for Polyester garments! The big key is to Hover with small periods of Direct pressure during curing (15 sec out of every 90).
We use this in retail and use it for everything. Cotton, cotton/poly blends, poly, everything. No staining, Use what you like but keep a gallon of this on standby for those hard to pretreat colors. the white ink sits right on top solid.!
Great service. Items came quickly. Great prices too!
