Man-Made fibers & the environment
By Amanda Zhou & Kirsten Steenblok

What are man made fibres
it will affect our human health

List of man made fibres

Rayon (1910) (artificial, not synthetic)
Acetate (1924) (artificial, not synthetic)
Nylon (1939)
Mod acrylic (1949)
Olefin (1949)
Acrylic (1950)
Polyester (1953)
Carbon Fibre (1968)
Vinyon (1939)
Saran (1941)
Spandex (1959)
Vinalon (1939)
Aramids (1961) - known as Nomex, Kevlar and Twaron
Modal (1960's)
Dyneema/Spectra (1979)
PBI (Polybenzimidazole fibre) (1983)
Sulfar (1983)
Lyocell (1992) (artificial, not synthetic)
PLA (2002)
M-5 (PIPD fibre)
Vectran (TLCP fiber) made from Vectra LCP polymer
Derclon used in manufacture of rugs

Consequences if nothing changes
Rayon, Viscose
and Acetate

•Can generate highly-polluting air and
water emissions
its fiber is are more strong, warmth, protection, affordable (cheaper than natural fibers), light and durable. (ex. nylon is elastic and resists creasing)
•Processing causes strong, unpleasant
• non-renewable resource
• long line of processing
they can be used in many forms such for weaving, knitting or carpet production and staple and can be spun into tread and used for fillings or nonwovens
• non-degradable
• non-renewable resource
• manufacture creates nitrous oxide, a
greenhouse gas 296 times more potent
than carbon dioxide for producing global
• long-line of processing
• dry-spun fibre and therefore more
polluting • long-line of processing
• no recycling infrastructure
it traps body heat making us sweat
they contain chemicals that may be harmful for our skins and they are not very comfortable
negative environmental aspect
many variety of colors are manufactured
Polyester (PET)
Don't buy man made fibres
Solutions & Alternatives
Buy natural fibres
upcycle old synthetic fibres
Donate them
How its Made

In order to manufacture man-made fibres,stringy liquids are needed
Man made fibres are made by man or machine. Chemicals are mixed until they form filaments, which are then woven into fabric.
Types of man-made fibres

Man-made fibres are classified into three classes, those made from natural polymers, those made from synthetic polymers and those made from inorganic materials.

Fibres from Natural Polymers

Fibres from Synthetic Polymers

Fibres from Inorganic Materials
Who benefits and suffers from man made fibers?
Many workers in Afghanistan synthetic fiber manufacturing, suffers from making the fibers with only glasses and a headscarf to protect them from the toxins of the fibers. the workers have to work to boost the Afghanistan's economy.
the fiber doesn't depend on an agricultural crop or on animal farming
They are easy to wash and dry
More resistant than natural fibres and can resist insects, fungi and rot.
fiber burns more rapidly than natural fibers and they are more prone to heat so they melt faster
more electricity charges is generating when rubbing, then natural fibers.

Another main issues of man made fibers is that it effects our health. because chemicals are used to manufacture synthetic fibers, the chemicals can enter the water supply and cause health problems. especially workers that make the fibers can have auto-immune diseases and disease of the lung.





Some of the environmental issues found man made fibers are that the production of the fibers energy use and generation of hazardous air emissions. And growing the natural fibers associated with man made fibers uses pesticides and degradation of the land.All of that damages the environment the oxygen we breathe in.

And the products made from petrochemicals take a long time to break down, and it would cause landfills.
and when the synthetic fibers are disposed in the ocean it would be a treat to the marine life, and it can led to food shortage.

Also many other workers in the world will have to suffer the harsh conditions, breathing in the toxins in the fibres, low wage, and long hours.
