These two fabrics are very different and belong to completely different types.
Polyester fabric is a chemical fiber and is not as comfortable to wear as pure cotton fabric. Pure cotton fabric is a natural fiber, which is comfortable to wear, has strong water absorption and good warmth retention. The production cost of polyester fabric is lower than that of pure cotton fabric. However, polyester fabric is strong and has good wear resistance, and can be processed into various styles of fabric. The production process of pure cotton fabric is relatively monotonous.
What are the differences between polyester and pure cotton? Finally, let's take a look at how to distinguish pure cotton fabric from polyester fabric.
The burning method: When cotton burns, the flame is smooth. Take a small amount of fibers and ignite them. Observe the ash left behind. If it is loose and can be crushed, it is cotton; conversely, if it melts first and then forms a solid mass that sticks together, it is polyester.
Pure cotton fabric: Near flame: Does not shrink or melt; Contact with flame: Burns rapidly; Away from flame: Continues to burn; Odor: Smell of burning paper; Residue characteristics: Small amount of gray-black or grayish-white ashes.
Polyester fabric: Near flame: Shrinkage; Contact with flame: Melting, smoking, slow burning; Away from flame: Continued burning, sometimes self-extinguishing; Odor: Special sweet and aromatic; Residue characteristics: Hard black beads.
2. It can also be compared by water absorption. Cotton is hydrophilic while polyester is hydrophobic. The water absorption of cotton is much better than that of polyester.
3. You can tell by the luster. If it reflects light very brightly, it is basically polyester.
