I think it depends on how the fibers in the clothes react to being placed in water. Natural fibers like cotton and wool absorb large amounts of water. The other thing would be what happens to the fiber when it dries (especially with heat). Not all fibers absorb water, nylon, polyester and lycra don't absorb much water. \n\nOne thing you could do for your project would be to take the same amount of some of these fibers in different containers and then pour in a certain amount of water. Then measure the amount of water that you can empty off. That will tell you how much water is absorbed.

The basis of most (more than 95%) refrigeration systems is the ' vapour compression cycle". The media (vapour) is Refrigerant (hydrochlorofluorocarbons - HCFC or hydrofluorocarbons - HFC) or freon which is non-toxic, non-explosive and non-corrosive. These Refrigerants have a boiling point of aprox. Minus 40°C which means that even if the air (outside or inside) temperature is as low as minus 39°C it still has heat to be absorbed by refrigerants. \n\nThe vapour compression cycle requires four components:\n\n1) The compressor: To raise the pressure of low-pressure low temperature gas to high-pressure high temperature gas. There are many types of compressors; the most common are Reciprocating, Rotary, Scroll, Screw and Centrifugal. \n2) The Condenser: To change the state of high-pressure, high temperature gas to high-pressure, high temperature LIQUID. This is achieved by passing ambient air (known as air-cooled) or water (known as water-cooled) over the condenser tubes. \n3) The Expansion Device: The purpose of the device is to change the state of the refrigerant from high-pressure, high temperature liquid to low pressure low temperature saturated liquid. This is achieved by passing the liquid through an orifice. \n4) The Evaporator: To absorb the heat from room air or water, which in the case of a chiller is circulated around the evaporator coil. This will change the state of low-pressure, low temperature saturated liquid to low pressure, low/medium temperature gas. \nThese components are common to the vast majority of domestic refrigerators and appear in slightly different forms in 95% of air conditioning and refrigeration systems, Domestic, commercial or industrial. This vapour compression cycle if reversed (condenser becomes evaporator and visa versa) can now absorb heat from outside and transfer it to inside, hence saving energy. This is called Reverse Cycle Heat Pump. Energy savings can be as high as 4 to 1 (for every kW input we get 4 kW output).

Cooling in the refrigerator. Drying clothes the vapor pressure changes exponentially. Populations and growth. (bugs, bacteria) Anything that grows in proportion to the amount.

Hi, The question is unclear...Thanks in advance--Cotton?

This can be achieved several ways for any fabric or substrate (wood, metal, china etc) using different transfer paper and/or inks.\n\n1st: For 100% cotton you use plastisol inks and for mixed cotton/polyester you can use dye sublimation inks - remember to buy prewashed fabric or be prepared to get your marigolds out or see your designs fade fast!  :)\n\n2nd: Your designs will have to be corrected depending on the color of the garment - using RIP software.\n\n3rd: You can apply these inks using Inkjet printers, Laser printers or traditional screen printing methods onto the specially coated transfer paper OR print direct onto the fabric/t-shirt using specially adapted Epson InkJet.\n\n4th: Sit with a pair of scissors and cut out your design or invest in a Roland cutting machine to do it effortlessly for you.\n\n5th: You then have to press the transfer onto the fabric using heat to activate the special inks to bond with the fabric. You can use a household iron or a swanky air operated heat press for approx 15-30 secs for each transfer.\n\n...As you can imagine, depending on your budget, there are many options. Go get a coffee, and meet the gang over at the screen printers forums below. Have a good read through "Digital Printing" forum threads before posting this question to everyone - there have been many upcoming printers that have started where your from...including me! - enjoy it and be prepared to be guided in making YOUR right decision based on location, orders, budget, type of hand(feel of print), local availability and quick delivery of inks and paper and fabric compared to speed of service in repair of printers, heatpress etc - Phew, I'm off to get a coffee!!!

Because of the nature of light energy, wave or particle. When clothes are wet, water fills the spaces between the fibers and forms a thin film on the surface. This diffuses light striking the clothes and also absorbs some of the energy, so less light is reflected. THt energy goes into heating the water, which is why your clothes will dry in the sunlight.

no benefit. And, due to how cotton chafes after it gets sweaty...i would say lots of downside.\n\nget yourself some of the dry wick synthetic fabrics. you will be much more comfie.

The latent heat of vaporization is very effective in cooling your body when your sweat evaporates. The fan will accelerate the process even more.

It's static electricity. They do have some sprays as well that you can spray on your clothes to control static electricity in your clothes. It might help. Moisture in the air will also help.

Not sure I understand what you are asking.\nYou can choose to specify either temperature or pressue at the saturation point, but not both.\n\nIf the refrigerant is boiling, that's a 2-phase solution. The mixture will range from all liquid to all gas without a change in pressure or temperature. It will be saturated vapor by definition.\n\nFor common refrigerants it is probably simpler to look up the information - it should be published or at least available from the manufacturer.

you need to look into what sportswear is made of. this is spec. designed to allow min sweating so its great stuff. gym wear and aerobics outfits.
