Cotton bale

Bale management encompasses the systematic procedures of categorizing, blending, and assessing bales based on fiber attributes, with the aim of achieving desired quality yarn production at an optimized cost.[4] Cotton fibres differ in terms of staple length and other physical characteristics; this is an inherent feature.[5] Bale management, also known as "bale mixing," is the process of analysing, classifying, and then blending fibres from various bales [which also includes the bales received from other stations] according to their fibre properties in order to create yarn of a specific quality at the most affordable price.[6]

A "bale of cotton" is also the standard trading unit for cotton on the wholesale national and international markets. 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]

The most important parameters of a cotton bale are:

• Density (448 kg/m³)[10]
• Measurements of the bales (nominally 1.40 m X 0.53 m X 0.69 m)[12][10]
• Weight (Varies, but ‘statistical’ bale weighs 480 lb)[10]

Advances in standardization are reducing the variation in weights, sizes, dimensions, and densities of cotton bales.[8][14]

Candy is another trading unit. A candy weighs approximately 2.09 bales (356 kg).[15] In India, ginned cotton is traded in terms of candy also which weighs 356 kg (355.62 kg).[16][17][11]
