For example, a red apple is reflecting red light and absorbing all other colors of light. The more light the object absorbs, the more heat absorbed since light is energy. If you consider it a color, black absorbs the most heat. A black object absorbs all wavelengths of light and reflects none. Objects that are white, on the other hand, reflect all wavelengths of light and therefore absorb the least heat.
First Velcro was made out of cotton by George De Mestral, although this cotton wasn't as strong as De Mestral had thought it to be. Today Velcro is made of various materials ranging from Nylon and pollyester to stainless steel and Synthetic fibers!
I've got an 80's evening jacket which feels very much like soft velvet. The content label shows the fabric is made from 64% viscose, 34% cupro, 2% metal. The jacket is by Jean Claire for after five.So far I've found that cupro is the European cousin of TencelÂ®, which in turn is the registered trade name for Lyocell, a biodegradable fabric made from wood pulp cellulose.owever, rayon is not considered a true synthetic either. So perhaps it is akin to rayon in that its natural materials, just processed to death. Tencel is made from cellulose too as you have noted. It is probably just processed to death in a DIFFERENT way and that is what makes it Tencel and not Rayon.
