The best thread count for bamboo sheets is 300. Thread count is the total number of threads in a square inch of fabric. This is calculated by adding the warp (the number of vertical threads) to the weft (the number of horizontal threads).
While it is commonly believed that a higher thread count on your bamboo bed sheets is always better, this is not necessarily true. Having too high a thread count can be detrimental to the quality of your bamboo bed linen.
Let us explore how thread count can affect your bamboo bedding when it is either too high or too low. Let us also determine the optimal thread count for your bamboo rayon sheets.
The Best Thread Count for Bamboo Sheets is 300
Much research and testing has shown that a thread count of 300 is optimal for bamboo rayon sheets. When the thread count is increased beyond 300, any additional improvement is insignificant, resulting in diminishing returns.
Therefore, bamboo bed sheets with a thread count of 300 feel buttery soft and luxuriously smooth while remaining refreshingly breathable.
What Can Happen if the Thread Count in Bamboo Sheets is Too Low?
When the thread count of your bamboo bed sheets is too low, they will not feel as soft or as smooth. Additionally, hard objects will more easily snag your bed linen due to the greater gap-to-fabric ratio. This can result in threads severing and your sheets will quickly fall apart.
What can Happen if the Thread Count in Bamboo Bed Sheets is Too High?
When a thread count is too high, it means that the weaver is using an extremely tight weave. Bamboo sheets that are woven too tightly have less breathability. Consequently, your skin will not be able to breathe as easily and you will perspire more frequently.
Moreover, very few mills can weave more than 400 threads per square inch. The sheet manufacturers that claim to have such high thread counts may have accomplished it by twisting two or more strands of thread together before starting the weaving process. Hence, they create a kind of 2-ply yarn and pass it off as double the thread count.
Furthermore, to compensate for the extra thickness of the 2-ply yarn, such manufacturers may have used thinner threads to create the yarn. Such inferior threads can break more easily or start to fray after a few wash cycles. As a result of fraying, pilling begins to occur as the yarn begins to unravel and this is evidenced by little fuzz balls all over your bamboo bed sheets. These unsightly pills may disturb your sleep because they feel lumpy and uncomfortable.
