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)
A way of determining the weight of an unknown yarn is to use the wrapping method. 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 ...
Avoirdupois is a system of mass based on a pound of 16 ounces, while Troy weight is the system of mass where 12 troy ounces equals one troy pound. The symbol g 0 is used to denote standard gravity in order to avoid confusion with the (upright) g symbol for gram.
It is also known as the strength-to-weight ratio or strength/weight ratio or strength-to-mass ratio. In fiber or textile applications, tenacity is the usual measure of specific strength. The SI unit for specific strength is Pa ⋅ m 3 / kg , or N ⋅m/kg, which is dimensionally equivalent to m 2 /s 2 , though the latter form is rarely used.
In the American oil industry, a sack represents the amount of portland cement that occupies 1.15 cubic feet (8.6 US gal; 33 L), and in most cases weighs 94 pounds (43 kg). [8] Other uses in the US include the measurement by volume of salt, where one sack is 215 pounds (98 kg), cotton where one sack is 140 pounds (63.5 kg) and flour, where one ...
Although different cotton-growing countries have their bale standards, for example, In the United States, cotton is usually measured at approximately 0.48 cubic meters (17 cu ft) and weighs 226.8 kilograms (500 pounds). [7] In India, the standard bale size is 170 kg. [8] [9] [10] [11]
In a yarn, moisture content is the moisture present in the yarn, expressed as a percentage of the total weight of the yarn. Moisture content is one of the most important tests on a yarn; [9] a fiber's moisture content will affect the entire manufacturing process, as it affects the physical properties of a material. For instance, during yarn ...
The grain was the legal foundation of traditional English weight systems, [5] and is the only unit that is equal throughout the troy, avoirdupois, and apothecaries' systems of mass. [6]: C-6 The unit was based on the weight of a single grain of barley which was equal to about + 4 ⁄ 3 the weight of a single grain of wheat.
