Characterizing Viscoelastic Size Film Fracture Dynamics under High Frequency Air Jet Shedding Stresses
Viscoelastic size film failure under high frequency air jet shedding stems from dynamic glass transition shift and energy dissipation limits.
Dynamic Psychrometric Microclimate Control and Viscoelastic Warp Film Stress in High-Speed Bast Weaving
Dynamic localized psychrometric control sustains viscoelastic sizing compliance on bast warps, preventing film fracture and lifting loom speeds past 500 PPM.
Quantifying Dynamic Thermal Elongation and Hysteresis in Synthetic Jacquard Harness Cords under Continuous Cyclic Load
Viscoelastic hysteresis and guide friction cause thermal cord elongation, degrading warp shed geometry during high-speed jacquard weaving.
Wet Spinning Trough Softening Physics and Linear Yarn Count Mechanics
Trough water at 70°C hydrolyzes middle lamella pectins to permit inter-fibre slippage, enabling high mechanical drafts down to fine linear yarn counts.
Cyclic Tensile Stress Decay in Wet Spun Flax Sized Yarns
Dynamic tension decay in sized wet spun flax yarns is minimized by controlling size penetration to 25 percent and keeping dynamic strain amplitudes below 1.2 percent.
