Recovery between Bamboo Fiber Fabric and Rayon Fabric
Firstly, bamboo fiber fabric has high recovery. No matter it is horizontal or vertical stretching, it never deform. So bamboo fiber fabric has high strength. However, rayon fabric has poor elastic recovery. If you stretch or wear clothes made of it, there will be wrinkles on the surface. So we can test the elastic recovery of the fabric to find out if it is bamboo fiber fabric or rayon fabric. This is the first way to distinguish between the two.
Color Fastness between the two Fabrics(Washing/Daylight/UV)
Secondly, bamboo fiber fabric has high color fastness. It’s not easy to fade when washing or in the sun. According to the data, bamboo fiber fabric has good anti-UV function which is 41.7 times that of cotton. So bamboo fiber is super anti-UV. However, rayon fabric is easy to fade in the sun. And it will shrink after washing. So we can see if the fabric will fade after washing or sun exposure to find out if it is bamboo fiber or rayon. To manufacture, the second way is testing color fastness to distinguish between the two.
Abrasion Resistance between Bamboo Fiber Fabric and Rayon Fabric
Thirdly, bamboo fiber fabric has high toughness and abrasion resistance. Despite this, its service life is short because it will be hard and dry after using for a period of time. So this is both an advantage and disadvantage. On the contrary, rayon fabric has poor abrasion resistance. It is easy to abrade after long time abrasion. So we can test the abrasion resistance of the two. This is the third way to distinguish between the bamboo fiber fabric and rayon fabric.
Antibacterial Effect between the two Fabrics
Finally, bamboo fiber fabric has antibacterial effect. When observing the same number of bacteria under a microscope. The bacteria can multiply in cotton and wood fiber products. While the bacteria on bamboo fiber products will be killed about 75% after 24 hours. But rayon fabric has no antibacterial function. Regardless of this, the rayon fabric has good alkali resistance. And various detergents is available for it. So we can test the pH value or antibacterial to find out if it is bamboo fiber or rayon. This is the fourth way to distinguish between the bamboo fiber fabric and rayon fabric.
Conlusion of how to Distinguish between the two Fabrics
Above all, we can test four aspects to distinguish between the two fabrics.
1.Elastic recovery (Better in bamboo fiber fabric)
2.Color fastness (Better in bamboo fiber fabric)
3.Abrasion resistance (Better in bamboo fiber fabric)
4.Antibacterial effect and pH value (Bamboo fiber fabric is antibacterial, rayon fabric is alkali resistance.)
Notice:In general, there are two kinds of bamboo fibers. One is bamboo rayon, the other is bamboo carbon. We usually call it bamboo rayon. So we talk about bamboo rayon fabric in this article.
