What is Nylon?
Nylon is the most useful synthetic material with applications varying from daily life activities to industries. It is a plastic which can be drawn into fibres or moulded into daily products for making amenities. We can live our entire life with nylon on our side. You hop across the nylon carpet to the kitchen, eat your breakfast on a nylon bowl after cleaning your teeth with a toothbrush whose bristles are made of nylon. A nylon umbrella over your head is used to move out of the house in heavy sunlight or to keep out of the rain.

The Science of Nylon
The term nylon points towards a polymer family known as linear polyamides. There are two approaches to making nylon for fibre applications. In the first approach, the molecules that consist of an acidic group (COOH) on every end react with molecules that contain amino(NH2) groups at each end. The resulting nylon gets a name based on the number of carbon atoms that separate two amines and two acidic groups. Hence, nylon 6,6 is widely used as fibres made from adipic acid and hexamethylenediamine.
The salt which is formed by two compounds is known as nylon that has an exact ratio of 1:1 acid to base. This salt is dried and then heated under vacuum to remove water and form the polymer.
In the other approach, a compound that contains an amine at one end and acid at the other are polymerized to produce a chain with repeating units of (-NH-[CH2]n-CO-)x. The nylon is referred to as nylon 6 if n = 5 which is another common form of this polymer. The commercial production of nylon 6 starts with caprolactam that use an open-ring polymerization.
In both the approaches, the polyamide is melt and drawn after cooling to obtain the desired properties of every intended use.
Properties of Nylon
- Lustrous
- Elastic
- Very strong
- Damage resistant to oil and many chemicals
- Resilient
- Does not absorb water
- Dries quickly
Types of Nylon
Nylon 6 – It was developed byPaul Schlack. It is formed by ring-opening polymerization.
Nylon 510 –It is obtained fromsebacic andpentamethylene diamineacid.
Nylon 1,6 – It is produced from dinitriles with the help of acid catalysis.
Nylon 66 –Wallace Carothers patentednylon66with the use of amide.
Uses of Nylon
- Clothing – Shirts, Foundation garments, lingerie, raincoats, underwear, swimwear and cycle wear.
- Industrial uses – Conveyer and seat belts, parachutes, airbags, nets and ropes, tarpaulins, thread, and tents.
- It is used to make a fishnet.
- It is used as plastic in manufacturing machine parts

FAQs
Nylon is a generic designation for a family of synthetic polymers composed of polyamide, which are repeating units linked by amide links. Nylon is a silk-like thermoplastic, usually made from petroleum, that can be melt-processed into fibers, films, or shapes.
What is nylon and its properties and uses? ›
It is elastic, very lustrous and easy to wash. It dries quickly and retains its shape. Uses of nylon: Nylon is used to make seat belts in cars, curtains, sleeping bags, tents, tooth brushe bristles, socks and ropes, It is also used to make parachutes and ropes for rock-climbing. It is used to make fishing nets.
What are the structural properties of nylon? ›
The physical properties of nylon are stronger tensile strength, high-temperature resistance, and more friction resistance than more standard, non-engineering plastics. The physical properties are as follows: Tenacity: 4-9 gm/den dry, in wet 90% of dry. Elasticity: The breaking extension is 20 to 40%.
What is the structure of nylon? ›
Nylon-6,6 is made from two monomers each of which contain 6 carbon atoms - hence its name. One of the monomers is a 6 carbon acid with a -COOH group at each end - hexanedioic acid. The other monomer is a 6 carbon chain with an amino group, -NH2, at each end. This is 1,6-diaminohexane (also known as hexane-1,6-diamine).
What are the 5 types of nylon? ›
What Are the Various Types of Nylon? The various types of nylon are nylon 1,6; nylon 4,6; nylon 510; nylon 6; and nylon 6,6. Nylons can be synthesized from dinitriles using acid catalysis. For example, this method is applicable for preparing nylon 1,6 from adiponitrile, formaldehyde, and water.
What are the uses of nylon? ›
The most popular use of nylon is plastic fasteners and machine parts. It is often commonly used in the electronics industry and nylon is used for screws, bolts, washers and nuts, and circuit board hardware. It is used to make bearings in the appliance industry due to its excellent abrasion resistance.
What type of nylon is used? ›
The most commonly used types of nylon for plastic injection molding are the PA 6 and PA 66 versions. Nylon has excellent strength, stiffness, heat resistance, wear resistance and lubricity, and chemical resistance to hydrocarbon.
What are the 3 main properties of nylon? ›
CHARACTERISTICS:
- Lightweight.
- Exceptional strength.
- Good drapeability.
- Abrasion resistant.
- Easy to wash.
- Resists shrinkage and wrinkling.
- resilient, pleat retentive.
- Fast drying, low moisture absorbency.
Typical properties: Highly fatigue-resistant and rigidity, better heat resistance, low friction coefficient, excellent abrasion-resistant, but has a greater degree of moisture-absorption and insufficient dimension stability.
What makes nylon strong? ›
Nylon is a lightweight synthetic polymer that also has long strands and hydrogen bonds, but it has a more ordered molecular structure than the cellulose in cotton, which gives it higher tensile strength. Like rungs of a ladder, the hydrogen bonds lock the rigid molecules into a tight formation.
Properties. Nylon 6 fibres are tough, possessing high tensile strength, elasticity and lustre. They are wrinkleproof and highly resistant to abrasion and chemicals such as acids and alkalis.
What is the definition of the structure of nylon 66? ›
Nylon 66 is made of two monomers each containing 6 carbon atoms, hexamethylenediamine and adipic acid, which give nylon 66 its name.
How can you identify nylon? ›
Observe the flame and the smoke produced by the burning fabric. Nylon fabric will melt and shrink away from the flame. It will produce a blue flame and will continue to burn after the flame is removed. Nylon also produces a strong, unpleasant odor similar to burning plastic.
What is the strongest nylon fabric? ›
CORDURA® is known for using Nylon 6.6 which is a particularly strong type of Nylon.
Is nylon stronger than cotton? ›
It is also much stronger than cotton, as cotton's natural fibers break down faster than nylon. Our strongest form of ballistic nylon (1680D) has a stronger anti-abrasion property and higher tensile strength than most of our cotton.
Is nylon a good or bad material? ›
Is it safe to wear nylon clothes? Since nylon is a synthetic fabric, it's treated with hundreds of harmful toxic chemicals during the production process. These toxins remain in your clothes and often penetrate your skin, leading to various health issues.
How is nylon 6 properties and uses? ›
Nylon 6 fibres are tough, possessing high tensile strength, elasticity and lustre. They are wrinkleproof and highly resistant to abrasion and chemicals such as acids and alkalis. The fibres can absorb up to 2.4% of water, although this lowers tensile strength. The glass transition temperature of Nylon 6 is 47 °C.
