Bleach Germ Bhuster

Clothing bleaching technique is already known by the ancient Egyptians before Pharaoh era. It was  hundreds of years before Christ, until about the year 1700, the bleaching done by the Egyptians. Namely by holding a cloth on the grass. Clothes they used a sheer fabric, which is not cut according to the pattern of fashion clothes. With the help of the sun's heat, the fabric on the grass, it can be pale white. This could be an old white-white, white and white were young dependent state. Sunlight can bleach fabrics we can prove that we hang colored clothing. Eventually this outfit so dull color. That's why we buy apparel from garment factories were given instructions, but do not be left in the sun dried in the shade of the roof alone. The ancient Egyptians also believed, bring in the deployment of solar thermal underwear reinforcing fibers to be durable. Confidence that makes sense if we remember that the cause of the clothing is not prolong  bacterial decay that undermines the cotton fibers from the cloth. With a degree in the hot sun in the spoilage bacteria was annihilated. Cleaning cloth while freeing germs in modern times was also performed by drying, but the crackdown bacteria carried by chemical drugs.

In 1700, the cloth weavers in the Netherlands found that Potassium Hydroxide it can also whiten fabrics. Even faster than the sun. Cloth dipped several times in a solution of potassium hydroxide, and then immersed in liquid milk leftover butter making. After the fabric is rinsed in water and held that white sunlight. Whitening cloth in this way is called Holland cloth. Why did they bother to whiten fabrics? Not because it would be shades of fabric and colorful images. Raw materials must white clean, so the results are not dull coloring. Bleaching process is not done then the grass field again, but in a textile mill room, before the material into cloth. Candidates fiber woven fabric bleached with bleach wasted that can vary its kind. Usually Sodium Hypochlorite, for cotton and flax. Material soaked in a solution of Sodium Hypochlorite substance for 2-20 hours, then rinsed with a solution of dilute sulfuric acid before drying. This solution prevents not to bleach it works so outrageous attack fiber cloth.

Wool and silk Hidrigenperokside bleached with a solution. This substance is releasing oxygen bleach, but not to attack the course material but their droppings. Wool handling sometimes also used sulphurous acid. The sour brimstone after joining of wool dyes to form a new compound that is colorless. If soapy water and then rinsed soft (containing potassium soap), then the material is left in the original color. More brilliantly again because it is free of dirt.

Later, bleaching agents are more practical use in the form of powdered calcium oxychloride. Substances such as calcium oxychloride complex arrangement of parts were not steady, consisting of Ca (OCl) 2 and CaCl mixed CaOH2. But sometimes simplified as CaCl CIO.

4H2O, a very unstable substance is a white powder smell of chlorine. In the water he was quickly shattered, releasing chlorine that is destroyer of germs. Because the substance that makes pale any goods, ranging from cloth to marble floors and porcelain tile, it is a powder that he circulated as bleaching powder. But often also referred to as bleach alone. While whitening ingredient, bleach also destroy germs the clhor loose with it. Chlorine is toxic to bacteria.

Ability as disinfectant then used to disinfect towels, pillow cases and sheets are due to the width and thickness of the surface is not entirely washed carefully. Also the floor where the children play, the bathroom floor, kitchen floor or other parts of the house that needs cleaning as it can be disinfected.

Calcium oxychloride can not be used for wool fabric, silk or fur coat color is not because the material is colored, but the original is colored so that the color does not fade. For domestic purposes is usually used Natriumperborat tetrahydrate. This stout substances used in household detergents and cleaning companies. Being able to release oxygen, he served as an oxidizing bacteria were crushed. Unfortunately only moderate efficacy.

Whiten substance to another household is diklorodimetilhidantoin (DDH) in the form of a white powder which is a bit of chlorine. When dissolved in water, it releases Hipochlor acid, HOCl little by little. Acid is a potent bleach textiles and fibers as well as an antiseptic.
