摘要： A method for producing spun yarn in an open-end spinning system having a rotary open-ended spinning chamber comprises feeding a bundle of fibers to the open-ended spinning chamber, rotating the open-ended spinning chamber at a peripheral surface speed V to successively accumulate superimposed layers of fibers upon the peripheral surface of the spinning chamber, withdrawing the accumulated fiber layers from the rotating open-ended spinning chamber in the form of spun yarn at a withdrawing speed W to self-double the spun yarn at a doubling number V/W, and selectively varying the speeds V and W to provide the spun yarn with a predetermined doubling number V/W during only a single passage through the open-end spinning system. The bundle of fibers is fed to the spinning chamber in a compressed air stream which transports the fibers in a mutually liberated condition to the open-ended spinning chamber.

摘要： A yarn having soft, attractive handle and a structure such that staple fibers are intertwined with each other to cohere into a substantially non-twist yarn. The yarn is manufactured by supplying a substantially non-twist strand of staple fibers to a fluid treatment zone where the staple fibers are intertwined with each other by the turbulent flow, at least part of said staple fibers to be supplied to the treatment zone having a length larger than the distance L between the fiber grasping point in the fiber feed zone and the point where the intertwinement due to the turbulent flow most effectively occurs.

摘要： A self-sealing dust bag for a vacuum cleaner provided with an inlet tube. The bag includes a body of relatively porous pliable dust-impermeable material and a relatively stiff plate portion provided with an aperture for the reception of the inlet tube. A patch of resilient elastic, dust-impermeable material is secured to the inner side of the stiff plate portion. The patch is provided with an aperture smaller than and in registry with the plate portion aperture. A bridge is integral with the stiff plate portion and extends over the aperture therein. The bridge includes a bulbous central section and two oppositely located connecting sections. The bulbous section is larger than the patch aperture and smaller than the stiff plate portion aperture. The bulbous section is frangible at the junction line between the bulbous section and one of the connecting sections to allow for the reception of the inlet tube in the stiff plate portion aperture.
