Because it stains less easier than regular steel. It's not 'stain proof', it's just more resistant to staining and rusting. Think of it as stain less.
Nylon carpet tends to be more resilient than other fibers, such as polyester or olefin (polypropylene). That means it will bounce back better when you move a piece of furniture, and won't wear down as quickly in traffic areas. It's also much more stain resistant than polyester. Look at the color swatches while shopping for carpet. Notice which fiber has a more brilliant array of colors available - polyester, right? That's because poly takes a dye much better than nylon. (Hence, it will absorb and hold stains better, too!) If you must shop for polyester, then be sure to look for those which have been treated to be stain-resistant. Watch the warranties. Olefin is more stain-resistant than nylon, but tends to feel scratchy while nylon is softer.
Certain acrylic sealers may be tintable but most water based stains require a topical sealer to be applied after you stain the concrete. We do make an all in one Trojan Color Sealer that incorporates a penetrating polyester sealer and UV resistant semi transparent stain in one product. The difference in our system is that it is not a topical that wears away over time. The polyester component fills the pores of the concrete and locks down the stain.
