Stain Resistance
A stain repellent is a product added to fabric in order to prevent stains. Stains Stains on Textile, fabrics are classified into three types: water-based stains and oil-based stains or a mix of both. Stain repellant fabrics Fabrics are finished with certain finishes that do not allow unwanted stains or that will wash out in simple laundry. Chemicals Mostly larger PFCAs such as perfluorooctanoic acid (PFOA) are used in stain repellancy. It is also known colloquially as C8. PFOA is a product of health concern and subject to regulatory action and voluntary industrial phase-outs. Alternative chemistry There are chemicals which are based on C8 free chemistry that may be used as an alternative to PFOA, but those are less durable.

Stain Repel
A stain is a discoloration that can be clearly distinguished from the surface, material, or medium it is found upon. They are caused by the chemical or physical interaction of two dissimilar materials. Accidental staining may make materials appear used, degraded or permanently unclean. Intentional staining is used in biochemical research and for artistic effect, such as wood staining, rust staining and stained glass. Types There can be intentional stains (such as wood stains or paint), indicative stains (such as food coloring or adding a substance to make bacteria visible under a microscope), natural stains (such as rust on iron or a patina on bronze), and accidental stains such as ketchup and synthetic oil on clothing. Different types of material can be stained by different substances, and stain resistance is an important characteristic in modern textile engineering. Formation The primary method of stain formation is surface stains, where the staining substance is spilled ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
