Cotton allows the sweat to evaporate.As we sweat profusely during summer cotton allows rapid evaporation the sweat evaporates using body heat leaving a cooling effect .woolen clothes have large spaces in between them which takes in a large amount of air . as air is a bad conductor of heat , it doesn 't allow the body heat to evaporate and we feel warm in woolen clothes
Cotton cloth is soft and let air in. it also absorb sweat .A cloth that lets lead air in is said to 'breathe'. The advantages of cotton cloth is that the sweat it absorbs evaporates because of the air it breathes
Synthetic dyes have varying levels of toxicity depending upon the source, but nevertheless, they are preferred over natural dyes because of the ease of availability and the inexpensive production of large quantities.
The advantages of synthetic detergents over soaps are :Synthetic detergents can be used even in case of hard water whereas soaps fail to do so. Unlike soaps, detergents do not form insoluble calcium and magnesium salts in hard water. They give lather in hard water also.Synthetic detergents can be used in the acidic medium while soaps fail to do so because of their hydrolysis to free acids.Synthetic detergents are soluble in water and hence form more lather than soaps.Synthetic detergents have a better cleansing action than soaps.Detergents do not cause irritation to the skin while soaps have this problem.
For your cotton clothes use a piece of paper toweling and a medium warm iron. Put the paper toweling over the wax and hold the iron on for a few seconds at a time until all the wax comes out. DO NOT USE THE IRON on your nylong gym pants. Put your gym pants in the freezer and pray you can chip the wax off the next day, then wash as usual.
Fabric softeners were invented when the detergent industry moved away from using "soap" and started using synthetic detergents, AKA surfactants, as the cleaning, foaming and emulsifying ingredients in laundry detergents. True soap forms familar soap-scum in hard water. A little of this was always left on clothes washed with soap and gave clothes just a touch of softness and flexibility (lubricity) but also could build-up over time causing dinginess. Surfactants generally rinse out of clothes very well and do not leave much of a residue. They left the clothes so clean that they felt harsh and stiff. Thus the need for fabric softeners. Fabric softeners also bring in another benefit - static reduction - which became very important as synthetic fibers and clothes driers began to be used more widely.
With evaporation you can't purify water.
The biggest advantage of cotton over nylon, especially in warmer climates, is that cotton fabric is much cooler to wear than nylon. Cotton can absorb the sweat where as nylon will have you feeling hot and sticky.
Advantage of the cotton gin was to speed up and have a more efficient production of cotton.
I personally would have thought that cotton clothes would be preferred, as they lock in the heat and keep the person warm, silk clothes look and feel nice, but do not provide as much warmth as cotton clothing would.
it doesnt
natural fabric a sobs more water the synthetic fabric. natural fabric is natural plants. synthetic fabric is man made.
cotton machines

Synthetic rubber is a man-made material that functions like natural rubber. Synthetic rubber is made with petroleum, which gives it multiple advantages over natural rubber.
because it made with plant cell and chemical. so rayon is not considered a true synthetic fiber
Yes if you dry them in the dryer, especially those made oh 100% cotton.
Synthetic fibres are used instead of cotton because they have the following advantages over cotton: (1)They are stronger and lighter (2)They not easily prone to moth-attack (3)They are wear-resistant and last for a longer time (4)They are crease-resistant and also wrinkle-resistant (5)They are easy to wash and absorb very little water (6) They have a lusturous appearance (7)They are elastic (8)It resists shrinkage (9)They are found in a variety of colors (10)They are mch cheaper than Cotton
