Synthetic & Performance Fabrics
Synthetic fibres are engineered to do what natural fibres cannot -- stretch and recover, shrug off water, dry in minutes and survive years of hard wear. From the nylon in a technical jacket to the elastane that makes jeans move, they are everywhere in modern clothing, usually working alongside naturals in blends. This guide covers the core synthetics, the performance and stretch fibres, and the recycled and technical materials shaping the future, with links to the finishes hub and the brands that use them.
Core Synthetics
Nylon
The original synthetic -- strong, light and abrasion-resistant.
What it is
Nylon was the first true synthetic fibre, prized for its strength, light weight and resistance to abrasion. It is smooth, quick-drying and takes water-repellent finishes well, making it a staple of technical outerwear.
Why it matters
Nylon's strength-to-weight ratio is hard to beat, which is why it appears in everything from lightweight shells to rugged Belstaff technical pieces. It is the workhorse of performance synthetics.
Polyamide
The technical name for nylon -- and what it signals on a label.
What it is
Polyamide is the technical name for the nylon family of fibres. When you see polyamide on a label, you are looking at a nylon-type fibre, valued for the same strength, elasticity and abrasion resistance.
Why it matters
Knowing polyamide means nylon helps you read labels with confidence. It signals a durable, performance-oriented cloth, common in sportswear, hosiery and technical layers.
Polyester
The versatile, durable synthetic used almost everywhere.
What it is
Polyester is a strong, wrinkle-resistant synthetic fibre that holds its shape, resists shrinking and stretching, and dries quickly. It is inexpensive, versatile and the most widely used synthetic in clothing.
Why it matters
Polyester brings durability and easy care to countless garments, often blended with cotton or wool to add resilience. Recycled versions cut its environmental cost considerably -- see below.
Performance & Stretch
Elastane & Stretch
The fibre that gives clothes their give and recovery.
What it is
Elastane (also known as spandex or Lycra) is an exceptionally stretchy fibre added in small amounts to give a fabric comfortable stretch and the ability to spring back to shape.
Why it matters
Just 2-5% elastane transforms how a garment moves and fits, from stretch denim to activewear. It is the quiet ingredient behind modern comfort. The amount and type of stretch is explained in the moisture and movement entries below.
Two-Way & Four-Way Stretch
How many directions a fabric stretches -- and why it matters.
What it means
Two-way stretch gives in one direction (usually side to side), while four-way stretch gives in both directions for full freedom of movement. The construction and elastane placement decide which.
Why it matters
Four-way stretch suits activewear and close-fitting garments where you move in every direction; two-way stretch is enough for gentler give. Matching the stretch to the use means comfort without bagging.
Moisture-Wicking
How synthetic fabrics move sweat away to keep you dry.
What it means
Moisture-wicking fabrics pull sweat away from the skin to the surface, where it evaporates quickly. Synthetic fibres and engineered mesh structures do this far better than cotton, which holds moisture.
Why it matters
Wicking keeps you dry and comfortable during activity and stops the clammy chill of sweat-soaked cotton. It is a defining feature of good sportswear and base layers.
Recycled & Technical
Recycled Polyester
Polyester remade from plastic bottles and waste.
What it is
Recycled polyester is made from post-consumer plastic, typically bottles, processed back into fibre. It performs like virgin polyester but with a far smaller environmental footprint.
Why it matters
It diverts plastic from landfill and cuts the energy and oil needed for new fibre, all without losing performance. Look for certifications like GRS to confirm genuine recycled content.
ECONYL & Recycled Nylon
Regenerated nylon from reclaimed waste.
What it is
ECONYL is regenerated nylon made from reclaimed waste such as fishing nets and fabric scraps, processed into a fibre identical in performance to virgin nylon.
Why it matters
It offers the strength and quality of nylon while turning waste into a resource, making it a favourite of sustainability-minded technical and swimwear brands.
Technical Fibres
High-strength specialist fibres for protection and durability.
What it is
Specialist synthetics include Cordura and ballistic nylon for extreme abrasion resistance, and aramid fibres for heat and cut protection. Fibre fineness is measured in denier.
Why it matters
These fibres go where ordinary cloth fails -- rugged bags, protective outerwear and workwear. They show how far synthetic engineering can push durability and protection.
Microfibre
Ultra-fine synthetic fibres for softness and function.
What it is
Microfibre is made from extremely fine synthetic filaments, finer than silk, packed densely for a soft, smooth surface that can also be highly functional -- water-repellent, quick-drying or cleaning.
Why it matters
Microfibre delivers a soft hand with technical benefits, used in everything from soft-shell jackets to linings. Its fine structure is what makes it feel good and perform well.
Frequently asked questions
What is the difference between nylon and polyester?
Both are durable synthetic fibres, but nylon is generally stronger and more abrasion-resistant with a slightly softer feel, while polyester holds its shape better, resists wrinkles and UV more, and is cheaper. Nylon excels in technical outerwear and hosiery; polyester dominates everyday and sportswear. Many garments blend the two, or blend them with natural fibres, to combine their strengths.
What is elastane and how much should a garment have?
Elastane (also called spandex or Lycra) is a highly stretchy synthetic fibre added in small amounts to give fabric comfortable stretch and recovery. A typical garment has just 2-5% elastane, which is enough to add noticeable give without changing the fabric's character. Activewear may have more for full flexibility. The rest of the garment is usually cotton, polyester or another main fibre.
What does moisture-wicking actually mean?
Moisture-wicking describes a fabric's ability to pull sweat away from the skin to its outer surface, where it evaporates quickly and keeps you dry. Synthetic fibres and engineered mesh structures do this well because, unlike cotton, they do not absorb and hold water. It is a key feature of sportswear and base layers, helping prevent the clammy, cold feeling of sweat-soaked clothing.
Is recycled polyester as good as regular polyester?
Yes -- recycled polyester performs essentially the same as virgin polyester in terms of strength, durability and easy care, but it is made from post-consumer plastic such as bottles, giving it a much smaller environmental footprint. It diverts plastic from landfill and uses less energy and oil than new fibre. Look for certifications like GRS to confirm the recycled content is genuine.
What is the difference between two-way and four-way stretch?
Two-way stretch fabric stretches in one direction, usually across the body from side to side, while four-way stretch fabric stretches in both directions -- horizontally and vertically -- for full freedom of movement. Four-way stretch is used in activewear and close-fitting garments where you move in every direction, while two-way stretch is sufficient where only gentle give is needed.
