|Title:||Field to Fabric Research on White Specks - Fabric Quality|
|Publisher:||Australian Cotton Growers Research Association|
|Abstract:||White speck neps cause significant financial losses to the textile industry and the following studies look at several factors that may affect white specks. Processing factors, such number of lint cleaners used at the gin, mill card settings, and combing are studied, as well as varietal differences, to see the effect on white specks in the finished fabrics. This paper examines the white speck phenomena as seen in the US and Australian studies. The first study has 4 extreme US varieties that were grown specifically to produce different levels of white specks. In this study, it happens that the tandem card was improperly set during insulation results in much higher levels of white specks than single carding, showing the importance of proper settings and maintenance. The second study looks at 26 US leading varieties studied (LVS) by AMS (Agriculture Marketing Service of the USDA, they measure what are perceived to be the important quality measurements on all cotton produced in the USA). This study also includes five extreme varieties grown in the same field (similar to the first study) and processed identically in the gin and mill. This shady also compares carding with combing. Four varieties from the 26 Leading Variety Study by AMS were carded and combed and the fabrics are analysed for white specks. The final two studies are collaborative studies between US and Australia. The cottons were gown in Australia and the studies compare ring to rotor spinning and different levels of lint cleaning at the gin. The first year used small seed cotton samples (300lbs) and the second year used full modules of seed cotton. Combing was found to reduce the white speck problem, while other processing seems to open and separate the immature fibers spreading the white speck problem. Ultimately we would like to develop strong predictions of white specks from high-speed instruments that test bale fibers, and have the white speck potential included in the classification of cottons.|
