64s

64s is not a single term with a universal meaning. It is a numeric-alphabetic designation that appears in several unrelated domains, and its interpretation depends on context.

In textile manufacturing, 64s refers to a yarn count. In cotton count systems, the letter s denotes singles, and higher numbers indicate finer yarns. A 64s yarn is very fine and may be used for lightweight fabrics such as dress shirts and other smooth fabrics. The exact properties depend on fiber, twist, and construction, but such yarns typically yield a high-thread feel and are considered premium in some markets.

In product catalogs, 64S (often capitalized) can appear as a model or variant code. The letter S commonly signals descriptors such as “Special,” “Sports,” or “Standard,” depending on the vendor. Because many unrelated products use similar codes, 64S alone rarely points to a specific item without additional context or documentation.

In timekeeping or sports timing, 64s would denote sixty-four seconds, though common formatting usually uses minutes and seconds (for example, 1:04) or a plain seconds notation in timer displays.

Because the term 64s spans distinct domains, disambiguation depends on the field and source. When encountering 64s, identifying the domain—textiles, product labeling, or timing—clarifies its meaning.
