The problem of byssinosis has plagued cotton textile mills for hundreds of years, and it is still a problem today. With the regulations on airborne raw cotton dust set by OSHA and the ACGIH, research regarding the measurement of cotton dust in lint fiber is a necessity. A procedure known as the mass concentration particle size distribution (MCPSD) technique, developed at Texas A&M University, was used to measure the characteristics of cotton dust as affected by harvesting method and genotype. Cotton genotypes from three harvest seasons were analyzed by using a Coulter Counter, Model TAII, to obtain the mass concentrations and particle size distributions of dust present in the lint fiber. The genotypes were subjected to both hand harvesting and conventional spindle harvesting for comparison purposes. Results from the dust concentration analyses of particles less than 100 micron, 16 micron, and 8 micron in diameter, respectively, are presented. Also, a proposed procedure to obtain large quantities of "cotton dust" from gin trash material is discussed.
棉尘病问题已经困扰棉纺织厂数百年，如今仍是个问题。鉴于职业安全与健康管理局（OSHA）和美国政府工业卫生学家会议（ACGIH）对空气中原棉粉尘的规定，对皮棉纤维中棉尘测量进行研究很有必要。德州农工大学研发的一种称为质量浓度粒度分布（MCPSD）技术的程序，被用于测量受收获方法和基因型影响的棉尘特性。使用型号为TAII的库尔特计数器，对来自三个收获季节的棉花基因型进行分析，以获取皮棉纤维中存在的粉尘的质量浓度和粒度分布。为作比较，对这些基因型棉花分别进行了人工采摘和传统纺锤式采摘。分别给出了直径小于100微米、16微米和8微米颗粒的粉尘浓度分析结果。此外，还讨论了一种从轧花废料中获取大量“棉尘”的提议程序。
