List of top Textile Engineering and Fibre Science Questions on Principles of winding processes asked in GATE TF

The twist angle (degree) of surface fibres in a yarn with density of 700 kg/m\(^3\) and twist multiplier of 6000 m\(^{-1}\).tex\(^{0.5}\) (rounded off to nearest integer), is ________________.
The Gibb’s free energy equation for a system undergoing phase transition is given by \( \Delta G = \Delta H - T\Delta S \), where \( \Delta G \) is the change in Gibb’s free energy, \( \Delta H \) is the change in enthalpy, \( \Delta S \) is the change in entropy and \( T \) is the temperature in Kelvin.
During melting transition, two systems A and B, show no difference in \( \Delta H \) but B exhibits 10% lower \( \Delta S \). The ratio of melting temperature of B to that of A (rounded off to 2 decimal places) is ________________.
In winding, if traverse speed and package surface speed are the same, the angle of wind (in degree) is \(\underline{\hspace{2cm}}\).
