Cotton bale

A cotton bale is a standard-sized and weighted pack of compressed cotton lint after ginning. The dimensions and weight may vary with different cotton-producing countries.[1]

Significance

edit

A bale has an essential role from the farm to the factory. The cotton yield is calculated in terms of the number of bales.[2] Bale is a standard packaging method for cotton to avoid various hassles in handling, packing, and transportation. The bales also protect the lint from foreign contamination and make them readily identifiable.[3]

Cotton bale management system

edit

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]

Standards

edit

Bale

edit

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]

Parameters

edit

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]
Country-wise bale weight[11]
Sr.No. Country Bale in kg
1 Australia 227
2 Colombia 233
3 Egypt 327
4 India 170[13]
5 Pakistan 170
6 Mexico 230
7 Nigeria 185
8 South Africa 200
9 Sudan 191
10 Tanzania 181
11 Uganda 181
12 United States of America 225

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

Candy

edit

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]

Trash

edit

When cotton is harvested and exposed to ginning, it carries more than 64% cottonseed, 2% waste and 34% fibrous matter (also known as lint).[18] Lower trash percentage in cotton increases the recovery.[19] Cotton bales are not pure cotton; they contain foreign contaminants, residual trash and leaf (and other non lint material) that have a direct impact on the recovery in yarn spinning.[20][21]
