What Is Polyester?

Polyester is a synthetic fabric which is made from a form of plastic known as polyethylene terephthalate (PET). It is made by combining terephthalic acid and ethylene glycol. 

There are some people who are opposed to polyester because its production is not from a sustainable source. However, many plastic bottles are recycled as polyester. But as it doesn’t break down too well it is somewhat problematic.

  • It’s Durable
    Polyester is a very durable fabric which is impervious to many chemicals, It is strong but lightweight.

What Is Fabric Softener?

Fabric softener was developed in the 1960s to treat fabrics after the harshness of dyes, detergents and tumble dryers. It is made from a mixture of chemical substances and is available in liquid or pod form for use in the washing machine and coated onto a plastic sheet for use in the tumble dryer.

It works by coating the fibres of the fabric of your clothes to soften clothes, reduce static and leave clothes with a fresh, pleasant fragrance. Which all sounds great but there are many concerns over the use of fabric softeners due to the chemicals used to produce it.

These concerns include health issues and serious environmental implications.

Health Issues

Many of the chemicals used to produce fabric softeners have been linked to various health concerns including;

  • Hexylene Glycol
    This has been linked with skin allergies, eye irritations and breathing problems and it is one of the main irritants associated with fabric softeners.
  • Benzyl Acetate
    Benzyl acetate has been linked with pancreatic cancer.
  • Ethanol
    Ethanol has been linked with central nervous system disorders.
  • Benzyl Alcohol
    Benzyl alcohol has been linked with many respiratory problems including coughs, breathing issues and asthma.
  • Glutaraldehyde
    This chemical is said to have been the cause of many skin allergies as well as asthma.

Sadly it doesn’t stop there, to reduce static buildup, fabric softeners contain quaternary ammonium cations (better known as quats). These quats are linked with skin allergies, many breathing problems, anaphylactic shock reactions and also reproductive problems.

The chemicals in fabric softener work by coating the fibres of the fabric making them slippery. This coating dries on and builds up over time. This can lead to the material becoming less able to absorb water.

Clothes get clean by absorbing water which loosens the dirt, sweat and bacteria and eventually washes them away. If the clothes lose their ability to absorb water, the dirt, sweat and bacteria will remain in the fabric.

As you can see, that’s not ideal especially when the whole idea was to clean the clothes. Worse still, is if the clothes were treated with a fire retardant. The fabric softener not only coats the fire retardant, but many chemicals in the fabric softener are highly flammable.

Environmental Concerns

Many of the chemicals found in fabric softeners are non-biodegradable which means they hang around for a very long time. Every time your washing machine rinses it expels waste water (and detergent & fabric softener) into the drain.

That water, including chemicals eventually finds its way into our streams, rivers and oceans where it damages the ecosystem. Fish, plants, invertebrates, algae, all get damaged by these harmful chemicals.

That has a knock on effect to birds and other wildlife that relies on that water or aquatic life.

Can You Use Fabric Softeners On Polyester?

If after reading all of the above, you’re still considering using fabric softener, there’s a few things you should know first. Polyester is a synthetic man made fabric that has been designed to be robust and fast drying.

Using a fabric softener can inhibit these qualities. Fabric softener can clog up the pores of the fabric making it less able to breathe and prevent any moisture wicking capabilities.

Fabric softeners can also leave a fat-like film on polyester which makes it look tired and worn. Plus fabric softener can also leave long streaky stains which can be difficult to remove.

We wouldn’t recommend using fabric softener on polyester. But if you still want to, we would suggest;

  • Opt For A Liquid Softener
    Liquid fabric softeners tend to be better at evenly coating polyester than dryer sheets.
  • Diluting It
    Watering it down first to help reduce the risk of that fat-like waxy deposit.
  • Add It To The Rinse Cycle
    This will help to prevent the softener from building up too much.
  • Don’t Use it On Sportswear
    Sportswear is designed to wick moisture away, fabric softener will clog up the pores of the fabric making it impossible to wick.

Will Fabric Softener Damage Polyester?

Polyester is a durable fabric and is designed to be robust. Fabric softener will not damage polyester, but it can leave unsightly streaks and stains or coat the fabric in a waxy, fat-like substance.
