The combination of bleed, stretch, construction restrictions and wearer abuse suggest they are not easily emblazoned ... even with screen printing.
1. The first barrier is adhesion. Slick Willie typically consists of polyester with spandex for elasticity. The latter affords a lesser raw material cost than the nylon garments but both types are highly elastic and comprised of very thin, slick threads. This leaves precious little surface area—since plastisol inks rely on mechanical more than chemical adhesion, they love a high surface-area textile. Surface area is a scarce luxury with the low denier yarns and tight, flat construction of performance fabrics.
2. Next is the “bungee-cord” issue: Performance fabrics wick away moisture and conform to every nook and [f=rgba(239,235,224,0.298039)]e not white and dyed-dark goods are prone to dye migration or bleeding.[f=rgba(239,235,224,0.298039)]cranny on the wearer. If the plastisol doesn't stretch, the garment won't form-fit the wearer. But, if it conforms, is not likely to be as durable.
3. If the garment is of the polyester persuasion, all but its bleached-white version will be dyed with colorants that consist of plasticizer—the main constituent of your plastisol ink. The caveat is that most of these garments ar
4. If this is not bad enough, just wait until you hear what they're going to do with these goods after you print them! They will stretch them over muscle, pad or bullet-proof vest, sweat profusely in them for hours on end, scrape them on anything and everything with which they come into contact and them dump them in a high-heat wash load with a good dose of rifle-cleaning compounds (also known as laundry detergents) and expect the shirts to last at least a few seasons.
