Polyester spun grey and white yarn is a type of strong and durable material used in making things like clothes, blankets, and other fabric items. It's made from synthetic polyester fibers, which are known for being tough and resistant to different conditions. The "grey" yarn is the natural color of the polyester, and it's often used in factories and industries.

It can be dyed to become different colors later. On the other hand, "white" yarn is already cleaned and brightened, making it great for everyday clothes and other things we use at home. Both grey and white polyester yarns are used in lots of different textile products.

Polyester is good because it doesn't wrinkle easily, is easy to take care of, and keeps its color well. Sometimes, polyester yarn is mixed with other fibers like cotton or wool to make fabrics even better.
