Why small polyester content in heather grey? Hiya,
I'm quite new to the t-shirt industry and I'm currently putting together a brochure. But something that's puzzling me is why do most (all?) manufacturers put a small percentage of polyester in the heather/ash grey shirts when the rest of the range is 100% cotton?
I'm sure its pretty obvious but I can't figure it out and I'd love to know.
Cheers
