POLYESTER is known for its breathability and moisture wicking properties. There is also excellent acid and alkali resistance, as well as UV resistance. The fabric of 75D multiples is generally polyester, such as 75D, 150D, 300D, 600D, 1200D, and 1800D, with a darker and rougher appearance than nylon.

Nylon has many advantages, including high strength, abrasion resistance, chemical resistance, and resistance to deformation and ageing. The downside is that it is difficult to manipulate. The sheen of the fabric is brighter and feels more slippery in 70D multiples of the fabric that is nylon, such as 70D, 210D, 420D, 840D, and 1680D.

  1. Composition

Polyester is a synthetic fabric made from petroleum-based products, while nylon is a synthetic fabric made from coal, water, and air. Polyester is usually made from a combination of ethylene glycol and terephthalic acid, while nylon is made from a combination of adipic acid and hexamethylenediamine. Both fabrics are made through a process called polymerization, where the molecules are chemically bonded together to form long chains.

  1. Strength and durability

Both polyester and nylon are known for their strength and durability. However, nylon is generally considered to be stronger and more durable than polyester. Nylon has a higher tensile strength, meaning it can withstand more stress and strain before breaking. This is why nylon is often used in applications that require a high level of strength, such as parachutes and climbing ropes. On the other hand, polyester is more abrasion-resistant, which makes it a popular choice for outdoor clothing and upholstery.

  1. Moisture resistance

Nylon is more moisture-resistant than polyester, which means it dries faster and is less likely to absorb water. This makes it a good choice for outdoor clothing, such as rain jackets and hiking pants. Polyester, on the other hand, is less moisture-resistant and can retain water, which can make it feel heavy and uncomfortable when wet.

  1. Heat resistance

Polyester is more heat-resistant than nylon, which means it can withstand higher temperatures without melting or degrading. This makes it a good choice for applications that require heat resistance, such as automotive and industrial textiles. Nylon, on the other hand, is more prone to melting when exposed to high heat.

  1. Environmental impact

Both polyester and nylon have a significant environmental impact, as they are made from non-biodegradable materials. However, polyester is generally considered to be more environmentally friendly than nylon, as it can be recycled and reused more easily. Nylon, on the other hand, is more difficult to recycle and often ends up in landfills or the ocean.

1. Nylon is more supple and softer than polyester.
2. The abrasion resistance is not significantly different.
3. Nylon has some flexibility. Polyester has no flaws.
4. Nylon dyeing is more difficult than polyester dyeing

In conclusion, both polyester and nylon have their own unique properties and are ideal for different applications. If you need a fabric that is strong and durable, nylon is the better choice. If you need a fabric that is more moisture-resistant and abrasion-resistant, polyester is the better choice. However, it is important to consider the environmental impact of these fabrics and choose a more sustainable option whenever possible.
