Functional Clothing: Thermal Wear
During the start of this assignment, I was still unsure what exactly counted as functional
clothing. After my past assignment, I knew I wanted to focus on thermal conducting clothing. I
researched scientific journals that
Discussion II and Report
1. Describe and compare fiber properties.
Rayon is a regenerated cellulose fiber therefore it has cellulose-like properties and
synthetic fiber properties.
Cotton print has a higher fiber count meaning that the fibers are thinne
Homework 3 for EMS 147/FPS 100
1. Explain the differences between the first and second order thermal transitions.
Why the second order transition is also important to polymer materials?
First order is a discontinuity in the first derivative of thermal ene
Homework 4 for EMS 147/FPS 100
1. Prove the First Law of thermodynamics dU dQ dW can be expressed into
dU TdS PdV fdl Vdr
Explain the meanings of all the symbols and the meaning of the expression.
dU: change in the systems internal energy
dQ: heat exchang
