How do you know bed sheets won't pill?

I've bought several sets of bed sheets in the past. Some pill quickly and I hate that. Others don't pill at all and stay soft forever. How do know which ones will and which won't? I always try to go for a higher thread count, but I'm not really sure how high you need to go. Also, someone told me that it depends on the type of fabric, ie. that a cotton/polyester mix is better than a 100% cotton- but I don't know if that's true or not. Anyone have any info?How do you know bed sheets won't pill?
Cotton/poly pill much more quickly than 100% cotton. The length of the fiber matters, too. The longer the fiber, the less it will pill. Have you still got the pilled sheets? Take a look at the fiber content tag - I'm guessing you will find they're short fiber 50/50 sheets. If you look for long staple (long fiber) high thread count cotton sheets (egyptian cotton, for instance) you won't run into pilling. That's all I buy anymore and I never have pilled sheets anymore. You do get what you pay for, but I have a 100% cotton twin sheet set for my son's bed I paid $10 for that's years old and still not pilled.How do you know bed sheets won't pill?
I always like 100% cotton with a fairly high thread count. You can get 600-800 thread count sheets for really good prices at places like Ross and Marshalls if you aren't really picky on color choices.
