Combining experiments and numerical simulations with a mechanical/statistical model of twisted yarns, we discuss the spinning transition between a cohesion-less assembly of fibers into a yarn. We show that this transition is continuous but very sharp due to a giant amplification of frictional forces which scales as exp θ, where θ is the twist angle. We demonstrate that this transition is controlled solely by a non-dimensional number H involving twist, friction coefficient, and geometric lengths…

Development of a Constitutive Theory for Short Fiber Yarns: Mechanics of Staple Yarn Without Slippage Effect
This article reports an attempt to develop a general constitutive theory governing the mechanical behavior of twisted short fiber structures, starting with a high twist case, so that the effect of
Mechanism of Yarn Failure
The importance of interfiber friction in determining yarn strength has been acknowledged by several authors. Studies of the effect of friction on yarn strength were often based on determining the
Bending Response of a Book with Internal Friction.
TLDR
It is found that the energy dissipated during deformation can be rationalized over 3 orders of magnitude, including the regimes of a thick stack with large deflection, which could be harnessed to design new classes of low-cost and efficient damping devices.
Development of a Constitutive Theory for Short Fiber Yarns Part II: Mechanics of Staple Yarn With Slippage Effect
A general constitutive theory governing the mechanical behavior of staple yarns and including the effect of fiber slippage during yarn extension is presented in this paper. A differential equation
Measuring geometric frustration in twisted inextensible filament bundles.
TLDR
The core is found to remain relatively hexagonally ordered with interfilament growing from the bundle center, driving the formation of defects at the exterior of highly twisted bundles.
A Theoretical Approach to the Problem of Yarn Strength
An idealized yarn composed of fibers with specified properties is treated analytically with the aim of determining the yarn strength at any degree of twist. The results are presented in the form of
Tensional twist-folding of sheets into multilayered architectures and scrolled yarns
Twisting sheets as a strategy to form yarns with nested structure lacks scientific guiding principles but relies on millennia of human experience in making catguts, food packaging, and redeployable
Self-Amplification of Solid Friction in Interleaved Assemblies.
TLDR
This model system provides a framework with which one can accurately measure friction forces and coefficients at low loads, and that has relevance to complex assemblies from the macro- to the nanoscale.
Nonlinear amplification of adhesion forces in interleaved books.
TLDR
It is concluded that the paper-paper adhesion force between the two outer sheets, on the order of a few [Formula: see text],  is the one amplified by the interleaved-book system.
Why Clothes Don't Fall Apart: Tension Transmission in Staple Yarns.
TLDR
It is argued the mechanism is generic, and in practical terms, it corresponds to a switch from a ductile to brittle failure mode accompanied by a significant increase in mechanical strength.
