Today, the textile industry has come a long way in providing the ease of use of textile products and producing products that are easy to maintain. Depending on the location and quality of textile products, a wide variety of fabric properties have been developed to offer different products to the customer. For example, in home textile products, tablecloths, tarpaulins and sports garments, fabrics are treated with dirt repellent to increase the usage properties of the fabrics. Today, a highly preferred finishing process, dirt repellent finishing, is also called stain repellent or stain repellent finishing.

This finish includes properties such as more difficult soil retention to textile products and easy removal of dirt from the surface. Dirt repellent finishing also serves to prevent the ability of textile products to retain greasy soils. Moreover, it facilitates the subsequent cleaning of the fabric.

Dirt on the rough surface of textile products, while various oils are mechanically attached. It then penetrates into the fibers and bound by physical forces. Such contamination is not the result of chemical bonding. Contamination conditions may be different. For example, if the surface of the product is not smooth, the texture of the fabric is not tight, the static electricity is very high, the yarn is less twisted, the fibers are very thin and the fibers are hydrophilic and lipophilic, so much pollution.

Oil impurities are substances which are insoluble in water but soluble in organic solvents. Examples of such impurities are various oils, such as oil paints, lipsticks and resins.

For physical tests performed in accredited laboratories, standards issued by local and foreign organizations are complied with. In this context, the following standards are taken into consideration in oil repellency tests:

• TS EN ISO 14419 Textile - Oil permeability - Hydrocarbon strength test
• AATCC 118 Oil repellency - Hydrocarbon resistance test
