What does "increased the ply count of the yarn" written in the bag description mean?
This question arises when reading the product description and encountering the unfamiliar weaving term "ply count of yarn," making it difficult to easily gauge the fabric's properties and durability.
The phrase "increased the ply count" in the bag description means that instead of using a single thick strand, multiple strands of thread were twisted together to weave a fabric that is thin yet sturdy.
Increasing the ply count of thread refers to a weaving method where multiple strands of thread are twisted together into a single yarn.
Generally, fabric woven from a single thick strand of thread tends to become thick and rough, whereas weaving with multiple plies of thin thread combined and twisted reduces the gaps between the threads, making the structure dense and tough. RYOO applied this method to the fabric of the R.S. Cotton bag [White], creating a big bag that is thin and light yet does not easily lose its shape[1]. It is a construction that adds durability at the yarn stage so that even when amply packed with items, the fabric does not easily stretch or fray.
hmmm, this is a fabric choice woven so that the bag's exterior remains lightweight while not losing its firmness when held in your hand.

The exact number of strands combined to weave the fabric could not yet be confirmed from the official materials.
