Starch is used for ironing your clothes. It is naturally found in seeds, roots and stems. Starch contains carbohydrates which is one of the important categories in the food pyramid for human diet. But it has other uses as well and one of them is as a laundry starch. It has the property of firming up on drying and so used for making crisp and smooth fabrics. It makes the fabric look more stiff and vibrant. It also acts as protective barrier because the dirt and sweat stick to the starch rather than clothes. It is easy to maintain and doesn't affect the fabric as it washes away with water.
Starch can be prepared with a lot of the carbohydrates that you have in the house. But the most popular and easy one is with rice or corn flour. Rice starch is made by adding rice to boiling water and by the time the rice is cooked completely, most of the starch from the rice gets into the water. This water can be used to starch clothes. This process is popular in India as people eat a lot of rice in these parts. Other method which I have mentioned below is with cornstarch powder. For making your own starch you require corn starch powder, burner, water and plastic bottle. Preparing your own starch does not take a lot of time and very easy to prepare and quite inexpensive.
