Cotton is a natural fibre. It’s growth depends upon the seasonal weather, climate condition and affection of paste and insects. So the properties of cotton fibres vary not only from lot to lot but also in same lot. The properties such as Micronaire, color grade, maturity measure the ability of dye absorbency of fibre. So if there is high variation of these properties in cotton then a significant variation of dye absorbency in fabric is observed. So the fabric, made form cotton yarn having inconsistent properties, generate complain of barré marks known as patta to our local people. To eliminate or minimize the problem of barré we must have to ensure the uniform distribution of cotton properties throughout the yarn manufacturing stages. And Bale Management is the procedure of determining mix laydowns by maintaining an appropriate combination of cotton properties with consistency through several mixes. Short and long term variation of fibre properties with in and between mixes is responsible for fabric barré which is possible to avoid by bale management.
