Abstract: The present invention is an air diffuser for distributing conditioned air to air jet spinning machines and the like that includes a tubular outer member formed with openings therein and a tubular inner member disposed within the outer member. The inner tubular member is made of a fabric material that is formed in part with a relatively closed mesh construction and in part with a relatively open mesh construction so that the inner member emits air over a predetermined arcuate flow path through the open mesh part. The inner member directs the predetermined arcuate flow path into the outer member so that part of the conditioned air diffuses directly through the outer member in the predetermined arcuate flow path, the predetermined arcuate flow path preferably being directed towards the spinning machine. The conditioned air is thus delivered to the spinning machine at localized areas and at a low velocity.
