How to distinguish nylon and polyester fabrics

The easy way to identify the composition of clothing fabrics is the combustion method. The method is to draw a strand of cloth yarn containing warp yarn and weft yarn at the seam of the garment, ignite it with fire, observe the state of the burning flame, smell the smell of the cloth yarn after burning, and look at the residue after burning to judge Whether it is consistent with the fabric composition marked on the clothing durability label to distinguish the authenticity of the fabric composition.

Nylon and polyester

Polyamide fiber, the scientific name of nylon, quickly crimps and melts into a white gel near the flame. It melts and drips and foams in the flame. There is no flame when burning. It is difficult to continue burning without the flame. It emits a celery smell. It is light brown and melts after cooling The material is not easy to grind. The scientific name of polyester is polyester fiber. It is easy to ignite and melts when it is near the flame. When it burns, it emits black smoke while melting. It shows a yellow flame and emits an aromatic smell. After burning, the ashes are dark brown lumps, which can be broken with fingers.
