Mechanics of Fiber Entanglements

Part 2: Influences of Fiber Entanglements on Drawing a Fiber from Fiber Assembly

Abstract

Experiments by a method which uses a strain meter have shown that inter-fiber contacts and entanglements have a considerable bearing on drawing fibers from variously oriented fiber assembly.
Force for drawing fiber from a parallel sliver shows only resistance force proportional to the fiber length. Force for drawing fiber from a fiber assembly is the sum of force proportional to the fiber length and force proportional to less than the cube of the fiber length.
Force for fiber-drawing from a lap in the carding process is produced by interfiber contacts and entanglements of drawn fibers.
