Thread Count
Thread count is probably the most advertised attribute for bed linens, yet it is not a very accurate indicator of true quality. Thread count is simply the number of yarns (threads) woven together in one square inch of fabric.
To achieve a high thread count, sometimes multi-ply yarns are used (a multi-ply yarn is one where more than one yarn is twisted together) and each of the plys are counted in the thread count. Whether a fabric is woven from single-ply or multi-ply yarns is not as important as the quality of the cotton used to spin the yarns.
Through technological advancements in weaving, thread counts can now range to over 1,200. The notion that more is better no longer holds true. Although a high thread count often denotes high quality, we suggest you take other attributes of bedding under consideration as well. These include the staple length of the cotton and the finishing techniques used.
There are four basic constructions of bedding
Percale weave is used for the majority of bedding. An even number of threads alternately cross over and under another, to produce a strong, even fabric.
Twill weave, identified by a diagonal rib or twill line, is used to produce strong bedding fabric that can have a softer “drape“ than a plain weave.
Sateen weave is used to produce smooth, lustrous, higher thread count bedding with a thick close texture. The number of yarns exposed on the surface of the fabric gives sateen its characteristic sheen.
Patterned weaves, such as jacquard and damask, are the most difficult and most expensive to produce due to their complexity, and are some of the most durable fabrics used in bed linens.
When considering flannel or jersey knit sheets, the weight of the fabric and quality of the cotton are more important than the thread count.
