本研究的目的是确定特定的植物成分存在于可吸入的原棉粉尘。原棉的几个等级之间的毛叶状（含苞片）垃圾的含量存在显着差异。例如，较高等级的原棉（严格低中棉= SLM）比较低等级的棉花（低中棉= LM）含有更少的叶状垃圾。在实验室中通过研磨试验确定了从植物垃圾材料加上棉绒和短绒产生细颗粒的潜力。苞片和木材碎片是最脆弱的所有植物材料中发现的原棉，而种子肉，皮棉，短绒和种皮是最不脆弱的。可吸入与中等、SLM和LM原棉的加工相关的原棉粉尘（小于10微米）预计含有以下重量%组成的特定植物成分：叶状= 70- 72%，茎= 13- 18%，树皮= 3- 8%，外果皮-中果皮= 3.6%，内果皮= 1- 2%和种子= 0.5- 2%。苞叶是可吸入性原棉尘中含量最丰富的成分。
The objective of this study was to determine the specific botanical ingredients present in respirable raw cotton dust. Significant differences in content of gross leaflike (bractcontaining) trash were found between several grade divisions of raw cottons. For example, higher grades of raw cotton (strict low middling = SLM) contained less leaflike trash than lower grade cottons (low middling = LM). The potential for production of fine particulate from botanical trash materials plus lint and linters was determined in the laboratory by an abrasive milling test. Bract and wood fragments were the most friable of all plant materials found in raw cottons whereas seed meat, lint, linters and seed coat were the least friable. Respirable (10 less than 10 micrometers) raw cotton dusts associated with the processing of middling, SLM and LM raw cottons were predicted to contain the following % weight composition of specific vegetable ingredients: leaflike = 70--72%, stem = 13--18%, bark = 3--8%, exocarp-mesocarp = 3.6%, endocarp = 1--2% and seed = 0.5--2%. Bract is the most abundant component in respirable raw cotton dust.
