why are some fabrics better absorbers than others?

Because of the fibers

less elements, so less complicated maths.  \n\nYou get a less accurate result, which I don't consider an advantage.

black absorbs heat, white deflects it

Probably because some of the air particles become trapped in your clothes, so they aren't completely released in the air to disperse.

If you are talking about regular speedo's.. the idea is that if you dont have fabric hanging out, you'll reduce your drag.. counter example.. a drag suit.. loose suit, more drag\n\nIf you are talkin about a Fast skin ( the tights, or full body ) they are designed to compress your muscles to optimize their performance.. dont ask me why it works.. but I know that when your muscles are compressed they lose less energy to vibration and last longer. but still they also make them tight so youre not dragging fabric around

because they use different material than each other

The essential answer to your question is YES - the absorption coefficient of a material reflects how well it absorbs acoustic energy.  This is another way of measuring the FREQUENCY RESPONSE of a material.\n\nAbsorption coefficients generally are qualified with a "typical operating range," that is, a range of frequencies over which the absorption coefficient is essentially correct (within, say, +/- 5% error - any good listing of absorption coefficients will list the accompanying error).\n\nFor most typical materials, the AAC is generally constant through the human auditory spectrum.  One notable exception to this is water - high frequencies are halted in water after only a few meters, but low frequencies (i.e., whale songs) can be transmitted over 10,000 miles away.

compressed air and microfiber cloth.

Because the feathers get matted together and loose their fluff. It is the trapped air in the millions of small pores that give it its insulating qualities. They are now combining goretex & down together in some applications. Synthetic down will hold its insulative qualities better when wet

In proper amounts there is expedited aging and decay of the fiber and color. Use only as needed for longer fabric life. That said simply wearing or washing fabrics expedite decay. Eleminating bleaches altogether isn't sensible.

Silk is extracted from the cocoon and spread out in a wide thin layer, stacked layer over layer. Air can easily permeate between the skin and the layer of silk, as compared to traditional cloth which is woven, with thread interlacing one another.  Thus, with more flowing air between the skin and silk, wearing silk is more cooling and keeping u dry.  On the other hand, air does not flow through the layers of silk, therefore keeping u warm.  Unlike the air gaps between the woven cloth and thread, therefore u feel cold when a gust of wind blows through

I suspect that what you mean is that the relative humidity is sometimes greater at night than it is during the daytime. This is because the air is warmer usually during the day, so it can hold more moisture.

simple it is because of refraction .\nas glass slab is more denser the speed of light is less \nas it comes out of glass into air (less denser than glass)speed increases

The colored piece of glass will absorb more light which will heat it up quicker.\n\nLight goes right through clear glass. Very little light/energy is absorbed.

The pads with the wings give you more coverage so you are less likely to get blood on your underwear.

because those are more padded and softer

nope.....and it feels soo much better than w/ underware....alot more freedom and no bunching...lol...nice question though
