Cotton Dust Controls in Yarn Manufacturing.

摘要

The purpose of this project was to develop optimum design criteria for cotton processing machinery local exhaust ventilation systems. The two principal areas of investigation were the configuration of exhaust hoods or other devices for capturing dust from cotton processing machinery and methods of filtering the particulate from the exhausted air. Dust capture devices and filters have been developed to maintain the airborne dust concentrations in the work areas below 0.5milligrams of dust per cubic meter of air as measured by the cotton-dust vertical elutriator. The design specifications were developed and specified for opening,picking,carding,combing and drawing machines of the most common types currently used in manufacturing cotton yarns.
