Given the linear density and weight the yarn length can be calculated; for example: l/m = 1693 × l m /Nec × m/kg, where l/m is the yarn length in metres, l m /Nec is the English cotton count and m/kg is the yarn weight in kilograms. The following length units are defined. Bundle: usually 10 lb (4.5 kg)
One way to determine the tpi for a single is to add a contrasting color fibre when spinning it, and then count the number of times the contrasting fibre has wrapped around the yarn. Another method is to measure an inch of yarn and untwist it, counting how many full revolutions it takes until there is no twist left.
This method is also used to calculate the amount of yarn needed for a project. By this method it is possible to check an unknown weight of yarn with a regular pencil and ruler [3] without unwinding the yarn. Simply slip the pencil under approximately an inch of the strands and count the number of strands. [3]
A pick glass also known as a piece glass is a magnifying glass helpful in counting thread count. It is used to determine the number of yarns in warp and weft in woven fabrics and courses and wales in knitted fabrics. [1] [2] Compact constructions of fabrics may have a higher thread count. That is also called "cloth count." [3]
Another measurement of yarn weight, often used by weavers, is wraps per inch (WPI). The yarn is wrapped snugly around a ruler and the number of wraps that fit in an inch are counted. Labels on yarn for handicrafts often include information on gauge, which can also help determine yarn weight. Gauge, known in the UK as tension, is a measurement ...
The S numbers originated in England, [4] where the worsted spinning process was invented and arose from the worsted yarn count system for stating the fineness of yarn. The worsted count (also known as the Bradford count) was the number of 560-yard (510 m) lengths (hanks) of worsted yarn that 1 pound (0.45 kg) of wool yields. [5]
Yarn weight is a factor; thicker yarns with less loft overall produce larger stitches than thinner yarns (reducing the number of stitches per width and length). Larger knitting needles also produce larger stitches, giving fewer stitches and rows per inch. Changing needle size is the best way to control one's own gauge for a given pattern and yarn.
A wrap reel or skein winder is a device for measuring yarn and making it into hanks of a standard size. The reel is of a standard size and its revolutions are counted as the yarn is wrapped around it. Typically, a set number of revolutions will be used so that the hank is of a standard size—skein or lea.
