Casein (Casein) contains amino acids and nitrogen needed by the body . Found in milk, 80% is characterized by white and yellow are both hydrophilic and hydrophobic molecules. Suspended in the water as hydrocolloids. (Hydrocolloid) to form a micelle (micelle) by casein can be processed using a fiber (Fiber) The fiber from the milk (Milk fibres) has stimulated the cells with the amino acids. The effect on the skin and moisturize the skin. It also has antibacterial properties and helps to stimulate blood flow. The technique electrolyte spinning. (Electrospinning) is a technique used to charge. Polymer fibers with dimensions from micrometers to nanometers. Made fibers with specific characteristics such as high specific surface area (specific surface area) ratio of length to width (aspect ratio) and high porosity (porosity) can be applied to various applications such as optoelectronics. (Optoelectronic) sensor technology (sensor technology) to change the rate of reaction (catalysis), filtration and medical, etc. [1] This research will use polyvinyl alcohol. (Polyvinylalcohol) as an aid in making emulsions and suspensions thicken (thickening agent).
