Studies on melt spinning of nylon 6. I. Cooling and deformation behavior and orientation of nylon 6 threadline

Journal of Applied Polymer Science, 1970
AbstractThe melt spinning of nylon 6 filament yarns was studied by measuring the filament tensions at the takeup roll, the filament temperatures θ(x), filament diameters d(x), and birefringence Δn(x) as functions of distance x from the spinneret, and by observing how the molecular orientation was affected by these differences in cooling and thinning ...

Compliant Pneumatic Feet with Real‐Time Stiffness Adaptation for Humanoid Locomotion

Advanced Robotics Research, EarlyView.
A compliant pneumatic foot with real‐time variable stiffness enables humanoid robots to adapt to changing terrains. Using onboard vision and pressure control, the foot modulates stiffness within each gait cycle, reducing impact forces and improving balance. The design, cast in soft silicone with embedded air chambers and Kevlar wrapping, offers durable,

Fabrication of Electrospun Chitosan/Nylon 6 Nanofibrous Membrane toward Metal Ions Removal and Antibacterial Effect

Advances in Materials Science and Engineering, 2016
Nylon 6/Chitosan membranes were fabricated by electrospinning onto a Millipore glass fiber filter to produce nanofibrous filter. Scanning electron microscopy (SEM) and water contact angle (WCA) were done to characterize the produced filter.
