Why is polyester as well as many other synthetic fabrics generally warm to wear in the summer and cold to wear in the winter?
Polyester and many other synthetic fabrics are generally warm to wear in the summer and cold to wear in the winter due to their unique properties.
Warmth in summer: * Low moisture absorption: Synthetic fabrics like polyester do not absorb much moisture, which means they do not feel wet or sweaty against the skin. This prevents evaporation and keeps the wearer feeling warm. * Traps heat: Synthetic fabrics create a barrier between the body and the outside environment, trapping heat inside and keeping the wearer warm.
Cold in winter: * Poor insulation: Unlike natural fibers like wool, synthetic fabrics do not provide good insulation. They do not trap heat well and allow it to escape easily. * Wicks moisture away: Synthetic fabrics tend to wick moisture away from the skin, which can create a chilling effect when the air outside is cold.
In addition, synthetic fabrics often have a smooth surface that prevents air circulation, further contributing to warmth in summer and cold in winter.
