See the huge variety in yarn only stores Cotton yarns can be so different Look for long staple cotton It shows in the wear Think of how short staple blue jean cotton shrinks and shows wear and then think of a shirt with 100% cotton with a bit of sheen that looked like new even when you outgrew it
Mercerization brings the sheen and brings out the color and makes it last Worsted yarn is totally different than thin crochet thread
I prefer mercerized worsted long staple cotton as it lasts forever and is silky and the color stays true for years . Pima ( American) and Egyptian cotton are superior as is Peruvian long staple cotton Here are some brands that I prefer When we read the label we understand more what we get with our money
In line Clip ( mercerized Egyptian long staple cotton)- thick and absorbent holds true colors for years and looks like new Mine outlasts store bought terry dishrags and towels I have some that are 4 +years old and look new and dry well and pick up water easily
Classic Elite Provence- again beautiful thick worsted mercerized long staple Egyptian cotton lovely stuff and lasts and lasts Brilliant vibrant colors that stay clear over time which is a joy and absorbent
P and C - 5/2 cabled mercerized cotton It is braided and lasts and is strong
Cotton tape ( discontinued ) by Rowan like flat shoe laces but made beautiful thick cushy cloths that are still workhorses in my kitchen and look great Might be able to find some on ebay or from Ravelers who are selling old yarn stash Not mercerized but nice
Cotton tots - available in non speciality stores Thick 2 ply with a binder thread wrapped Makes lovely facial cloths and baby blankets I have a few dishcloths from this which again are coming up on 5 years old and look great ( not mercerized but very very soft)
Cotton Fleece- thick and cushy and soft and absorbent
There are many other great brands and I am slowly trying more
Please do not think that one can know about cotton knitted items if one does not explore all that is available If we pay a bit more up front -it saves when the item lasts for years. I have a friend who has hand knit cloths from over 10 yrs and still going strong Mine are not faded/not worn and look great after years of use I wash several a week as I believe in only one days use ( warm and wet breed germs) so they are washed often without special care. I also put my sponges and Tuffys in high temp dishwasher to sterilize them ( 150 degrees) but as they wear out I am replacing them with knit ones

happy knitting
