Recycled synthetics may be made from pre-or post-consumer synthetic fiber waste. The two most common forms of recycled synthetics are recycled polyester and recycled nylon polyamide.
Recycled polyester may be made from pre-or post-consumer waste, and post-consumer recycled bottles are the most common source of recycled polyester. Recycled polyester is often referred to as rPET. Pre-consumer polyester may include waste from the spinning of yarn or the cutting of garments. Post-consumer waste includes plastic PET bottles, industrial fishing nets as well as some used clothing. Methods of recycled may be mechanical (melting plastic and then extruding into yarn) or chemical (going back to the monomer or polymer phase before extruding yarn).
Recycled nylon is processed chemically, similar to recycled polyester. It usually is made from pre-consumer spinning or fabric waste and may also come from post-consumer industrial fishing nets.
HOW MUCH POLYESTER IS RECYCLED?
In 2016, polyester fiber production is estimated at 52 million MT.
At less than four million MT, recycled polyester (which is the key fiber in preferred synthetics) makes up an estimated seven percent of polyester fiber produced — these fibers are largely used in carpets, blankets, clothing, and other textile applications.
Government initiatives increased awareness, relatively low production cost, and increase in virgin polyester uptake have seen a surge in recycled polyester growth — which is expected to continue — with China, India, Japan, and the US projected to account for the highest production.
RECYCLED POLYESTER SUPPLY CHAIN
The general process of transforming seed cotton from the farm into the final garment includes ginning, spinning, weaving/knitting, dyeing, finishing, cutting, and sewing. Organic certification ensures that the cotton passing through each stage of the manufacturing process is tracked.
RECYCLED SYNTHETICS STANDARDS
The Recycled Content Standard (RCS), or the Global Recycled Standard (GRS) verifies that the raw material is recycled, categorizes it as either pre-consumer or post-consumer, and then tracks the material through to the final product. The GRS provides additional social and environmental processing criteria. Other voluntary sustainability standards that cover recycled materials include the SCS Global Services’ Recycled Content Certification.
All about Synthetic fabrics
Synthetic fibers are inorganically made man-made fibers, made from chemicals based on oil products And Synthetic fabrics are made from synthetic fibers as a substitute for natural fabrics, with the better qualities of these natural fabrics in them.
The chemicals used to make the synthetic fibers like sodium hydroxide and carbon disulphide are derived from coal, oil, or natural gas.
All synthetic fibers are filament fibers with a rod-like structure, long, circular when cut in a cross-section. The synthetic fabrics have a smooth and shiny appearance. They are lightweight but very strong, much stronger than the natural fabrics – a very desirable quality; they are all poor conductors of heat; They are generally easily maintainable, with less creasing. The fabric dries quickly. They have natural elasticity and flexibility. Easy maintenance is what attracts it to you and me as clothing fabrics. These fabrics are, to top it all, inexpensive.
Now to the bad- Synthetic fabrics do not have the breathability of natural fabrics. They do not absorb moisture, which makes them rather uncomfortable on the skin. All of them melt with a chemical odor when put to flame and leave molten beads as residue. This will stick to your skin if you are wearing it when it is melting. It is considered as a Burn Hazard by the US military.
The cost to the environment due to the manufacture, use and disposal of synthetic fabrics are many – air pollution and water pollution are the first things (and the worst) that come to my mind.The fact that they are non-biodegradable and can remain in the same form for many many years spells even more doom.
However bad or good or the best you think they are, there is no escaping from synthetic fabrics for us humans.” The global market size of synthetic fiber is projected to expand at a compound annual growth rate of 7.25% between 2018 and 2023″
Synthetic fabrics derived from petrochemicals make up 65% of all textiles produced globally with polyester being the most used.
Growing consumer concern about the climate crisis and micro-plastic pollution makes switching to more sustainable alternatives an attractive opportunity.
A growing market for sustainable sources of synthetics has emerged including recycled fibers (mainly from other waste plastic but also some from reusing textile waste) and bio-based (rather than oil-based).
Up to a million tons of plastic microfibres pollute oceans and waterways each year from the washing of synthetic clothes.
In 2015, polyester produced for clothing emitted 282 billion kg of CO2 – nearly three times more than cotton.
Polyester does not biodegrade in landfills and, if produced without proper wastewater treatment systems, releases dangerous substances into the environment.

In the last 10 years, a new generation of recycling has emerged which takes synthetic materials already in existence (plastic bottles, ocean plastic, pre & post-consumer waste textiles) and recycles them into new quality fibers.

Other Synthetic Fibers
Acrylic, polyamide, nylon, polypropylene, PVC, spandex (AKA lycra or elastane), aramid, etc, are all different types of synthetic fibers that are derived from petroleum and therefore have a very similar impact on the environment as polyester.
1. Nylon
Nylon is one of the most used synthetic fabrics; Since it was produced as a replacement for silk by DuPont, it has had unprecedented growth in usage across all sectors – apparel,, industrial, home furnishing, automatic, construction, etc. The nylon fabric is preferred for its qualities like strength, resistance to abrasion, flexibility, quick-drying, water resistance, etc.
You can learn more about Nylon fabric here.
2. Polyester
Polyester was another discovery by the DuPont company. It is now the most popular apparel fabric in the world. The durability and strength of polyester fabric along with its cost-effectiveness and easy maintenance make it the chosen fabric for most fast-fashion labels.
Read more on Polyester fabric and Polyester fabric care for answers to frequently asked questions like “Will polyester shrink” etc.
3. Acrylic
Acrylic, the fabric that closely resembles wool fabric is a pure synthetic fabric. It is understandably made as a substitute for wool. You get acrylic wool yarn which can be knitted into fabric or you can buy acrylic clothing at a fraction of the price of wool, but just as warm and soft. In fact many wool garments that you buy may be made of acrylic. The un-informed person can easily be fooled because of its close resemblance to wool in softness and appearance. Read more about acrylic fabric here.
4. Spandex
Spandex is a true blue synthetic fabric made of Polyurethane with a lot of elasticity; an alternative name for spandex is Elastane. It can stretch up to 400% of its original length and spring back in the same condition. It is lightweight and can wick moisture from the body. This fabric is the most popular choice for clothing that requires flexibility like sports apparel, exercise wear, form-fitting clothes, swimwear, etc. Most of the casual clothing today will have some amount of spandex fibers woven into its fabric.

5. Olefin
“Olefin fiber is a synthetic fiber made from a polyolefin, such as polypropylene or polyethylene” Wikipedia. It is not much of an apparel fabric but it is widely used in home furnishing, making ropes, etc. It is one of the most environmentally friendly fabrics among the synthetic fabrics as the production process is so and it is recyclable. It is strong, lightweight, durable, and is available in many textures.
6. Synthetic fur, leather and Suede
Synthetic fur/ leather and suede are manufactured to replace costly leather and suede and have most of the appearance of fur/leather/suede right about them. Synthetic suede resembles suede leather. They are widely used to make accessories like bags, shoes, belts, etc as well as clothes like pants, jackets at very less cost than that of leather/suede or fur. Synthetic leather is made with a polyurethane face and has a knit or woven backing. The synthetic suede is made of nylon/polyester blended yarn and then the fabric is brushed to get the appearance of suede
