EVOLUTION OF DRAW-FRAME DRAFTING

The design of an ideal draw-frame involves such factors as friction, load, adhesion, fiber mass and orientation, and drafting force. Fiber control is basically achieved through the type, diameter, and arrangement of the rollers and the load on the roller. Roller setting is critical to optimal drafting in which the fibers pass through the ..

SPINNING NOMEX-ARAMID FIBERS ON COTTON SYSTEM.

Technical difficulties that were encountered and production parameters that were used for spinning Nomex-aramid fibers into 32.8 and 14.8 Tex yarns using cotton system machinery are described. Procedures and machine settings for precarding, carding, drawing, and spinning are specified. The density, strength, elongation, imperfections, and..

HIGH DRAFTING IN CONVENTIONAL AND ALTERNATIVE SPINNING PROCESSES.

The development of high speed drafting systems is traced from the 19th century to the present. Factors that favored the development of high speed drafting after 1945 are outlined. The development of high speed drafting systems for drawing-frame sliver spinning during the 1950s is reviewed. The reasons for the ultimate failure of this tech..
