It is also observed that the relative wind incidence angle and the local power coefficient of the Magnus cylinder are independent functions of spin ratio.
Effects of varying blend ratios, spinning temperatures, and molecular weights on fiber formation were studied and optimum conditions for formation of uniform non-woven fiber mats with potential applications for air and water filtration were obtained.
The tensile strength and modulus of blend fibre increased with TLCP content and spin draw ratio.
The 100 µm-thick gas-permeable PDMS membrane was made by spinning premixed 10∶1 ratio of PDMS prepolymer and curing agent (Sylgard 184 kit, Dow Corning) on a thoroughly cleaned silicon wafer vacuum-adhered to a precision spinner (Laurel).
The universal banks have remained largely above the fray in recent days, but on October 1st, UniCredit, a big Italian bank, announced plans to raise its capital ratio by spinning off property assets.
Increasing the jet stretch ratio during spinning had a detrimental effect on solid polymer selectivity.
The concentration of the spinning solution and the ratio of chitosan/collagen were varied and adjusted to get smooth nanofibers.
One of the latest growth areas in the academy is in "security demographics", where scholars are invited to predict the potentially dire implications of demographic change, and one of the most gloomy prognostications is rooted in what could happen when sex ratios spin out of kilter.
Furthermore, based on the formula, the laws of initial thickness and initial diameter of workpiece, diameter and splitting angle of splitting roller and feed ratio of splitting spinning influencing on splitting spinning force are investigated.
The fiber spinning velocity and fiber draw ratio was measured to be between 140 and 160 m/s and 1 300,000, respectively, for fibers spun from 10 wt% polyacrylonitrile (PAN) solutions with dimethylformamide (DMF).
