What ring-spun yarn means
Short answer: Ring spinning is a way of spinning thread where the fibres are twisted more tightly together. It gives a stronger and more even yarn than the faster spinning methods.
Two ways of spinning
Ring spinning is slower and more expensive but gives a more even thread. Faster methods give a more uneven yarn.
What you can feel
An even yarn gives a smoother surface and a fabric that pills less. The difference shows over time.
Why it is not always stated
The spinning method is rarely stated on the label. Instead it shows in how the fabric looks after six months of use.
Fibre length also matters
Long fibres spun tightly give the strongest yarn. Short fibres work their way out and turn into pilling. See pilling on clothes.
Quality rather than price
It is one of the things that explains the price difference between two t-shirts that look alike. See quality t-shirt versus cheap t-shirt.
