Thread count refers to the number of threads woven into one square inch of fabric in a bedsheet, pillowcase, or other textiles. It is a measurement of the density of the fabric and is often used as an indicator of the quality and softness of the material. The thread count is determined by counting the number of horizontal (weft) and vertical (warp) threads per square inch and adding them together.
Traditionally, a higher thread count was believed to indicate better quality and softer fabric. However, in recent years, the significance of thread count has become somewhat debated. Manufacturers have sometimes inflated thread counts by using multi-ply threads, which means that each thread is made up of two or more thinner threads twisted together. This can artificially inflate the thread count without necessarily improving the quality or feel of the fabric.
While a higher thread count can contribute to a softer feel, other factors such as the quality of the cotton, the weave, and the finishing processes also affect the overall quality and comfort of the fabric. It's important to consider thread count along with other factors when choosing bedsheets or other textiles.
