Difference Between Polyester and Nylon

Thekey differencebetween polyester and nylon is thatnylon is a synthetic polymer whereas polyesters can be natural or synthetic.

聚合物大分子,有相同的圣ructural unit repeating over and over. The repeating units are called monomers. These monomers are bonded to each other with covalent bonds to form a polymer. They have a high molecular weight and consist of over 10,000 atoms. In the synthesis process, which is known as polymerization, longer polymer chains are obtained.

Polymers have very different physical and chemical properties than their monomers. According to the number of repeating units in the polymer, its properties differ. There are a large number of polymers present in the natural environment, and they play very important roles. Synthetic polymers are also used widely for different purposes.Polyethylene,polypropylene, PVC, nylon, and Bakelite are some synthetic polymers. When producing synthetic polymers, the process should always be highly controlled to get the desired product.

What is Polyester

聚酯是酯官能团的聚合物。由于有很多酯，因此被称为聚酯酯。有天然的聚酯和合成的聚酯。此外，根据主链的组成，有几种类型的聚酯。它们是脂肪族，半芳香和芳香的聚酯。聚乳酸和聚糖苷酸是脂肪族聚酯的例子。聚对苯二甲酸酯和聚丁烯三乙酸酯是半芳香族聚酯，而Vectran是芳香族聚酯。

Synthesis of polyester is done by a polycondensation reaction. A diol with a diacid reacts to produce an ester linkage and this polymerization continues till the desired polyester is synthesized. Polyesters are widely produced and have a large market after polyethylene and polypropylene. Polyesters arethermoplastics，因此热量可能会改变其形状。此外，它们也可以是热固性。当暴露于较高的温度时，它们是可燃的。

Polyester is used to produce fabrics. These fabrics are used to make clothes like pants, shirts and jackets. Moreover, they are used to make home furnishings like bed sheets, blankets, etc. Polyester fibers are also used to make bottles, filters, insulating tapes, etc. Natural polyesters are biodegradable, so they can be recycled. They have really good mechanical and chemical properties, which allow them to be used for many purposes as mentioned above. Another advantage of polyester is its low toxicity.

What is Nylon?

Nylon is a polymer with amide functional group. They are a class of synthetic polymers. Nylon was the first successful synthetic polymer. Also, it is one of the most widely used polymers. Nylon is a thermoplastic and is a silky material. When synthesizing a polyamide like nylon, a molecule with carboxylic groups is reacted with a molecule having amine groups at both ends. Nylon was produced as a replacement for silk to make fabrics and such materials.

What is the Difference Between Polyester and Nylon?

In polyesters, the ester functional group is present whereas, in nylon, the amide functional group is present. Nylon is a synthetic polymer whereas polyesters can be natural or synthetic. Moreover, polyesters can be thermoplastic or thermoset, but nylon is thermoplastic. Nylon fabrics are more naturally felt than polyesters.

概括– Polyester vs Nylon

The key difference between polyester and nylon is that nylon is a synthetic polymer whereas polyesters can be natural or synthetic. Moreover, polyesters can be thermoplastic or thermoset, but nylon is thermoplastic.
