However, rayon is so prevalent that even its enemies feel compelled to use it. According to Benedek, rayon does not clean as well or last as long as cotton, silk, or linen. The chemicals used in making rayon degrade into toxic substances when it burns. The average life span of a garment depends on how it is made. If it's sewn together then the material will break down over time, if it's printed then it will wear away over time. However, if it's painted then it will probably last for many years. Garments that are washed regularly can be worn for longer because they are kept clean and smell nice. You can also add some stains to your clothes - such as coffee or red wine - and they'll look good later this morning! Clothes that aren't cleaned often may seem clean but are really full of dust particles from being ignored. These particles become airborne when you move around or open a window and can end up in other items that are not worn anymore. This can also happen with old furniture or equipment that has been thrown out at someone's house. Even though it may look like it's clean inside, any germs on the surface could still be present. So, yes, rayon garments can last for several years if they are taken care of properly.
