There are several ways to determine whether the jute pad is glued:
Observe the color and texture: high-quality natural jute usually has a natural soft luster, is light yellow, and looks natural. If the color is dull, dull and white, it is likely that glue has been added. At the same time, the gummed jute feels harder, while the pure feel is smooth and soft. Smell: If the jute pad has a strong pungent smell, it is likely that glue has been used. However, it should be noted that some jute pads in order to prevent insects or increase hardness, will use some chemical treatment, then there will be a similar chemical smell, but not necessarily glue. Check the edges: If the edge of the jute pad is smooth and there are no fibers scattered or cracked, then glue is most likely used. Pure natural jute MATS may have fibers scattered or rough edges after cutting or polishing.
Do a burn test: Take a small sample of jute mat and perform a burn test. Real jute will show a natural yellow flame when burned, and the ash will be gray after burning. If glue or other substances are added, other colors of flame or odor may appear when burning.
Check labels and certificates: If the above methods still cannot determine whether the jute mat uses glue, you can check the product label and related certificates. Jute MATS sold through formal channels are usually marked with the use of glue or other chemicals.
It should be noted that the above method can only be used as a reference, and it cannot be completely determined whether the jute pad uses glue. If you have doubts about the jute mat you purchased, it is best to consult a professional or manufacturer.
