Meet Polyester! A Bit More About the Fabric

Polyester has achieved huge popularity these days compared to natural fabrics. But is it also natural, or is it synthetic?

To be precise, polyester does contain chemicals but they are naturally derived from plants. In addition, it also consists of synthetic fibers. So, we can say that this fabric is a 50/50 combo.

Since polyester is often mixed with the fully natural fibers (e.g. cotton), such fabrics have combined qualities.

Polyester can add strength and tear-resistance to natural fabrics together with the resistance to wrinkling and shrink. As for synthetics, it makes them more wind and waterproof. 

The only weak spot of this super fabric is its tendency to ignite and melt when being exposed to fire.

What about the ability to shrink the polyester fabric? 

Let’s examine this issue closer.

Since polyester does contain synthetic fibers, it is necessary to look after it carefully just like we would do with any synthetic material.

Even though this kind of fabric is rather strong and durable, it doesn’t mean that polyester apparel doesn’t require any proper care.

To keep your blouses, skirts, and other garments neat all the time, just take into account several simple tips to make the maintenance process simpler.

  • Polyester is very easy to get stained since it attracts and holds dirt and stains extremely fast and good
  • Always wash polyester-made stuff turned inside out to protect the garment from ruining
  • For tumble-drying, set the machine to the low heat regime
  • The static electricity on the polyester items can be reduced by laundering it with the softener for fabrics
  • Ironing is allowed only in a moderate heat setting. As an option, a steamer is safe to use

This fabric isn’t considered to be hard to maintain, nevertheless, proper care will significantly extend the lifespan of polyester apparel. Careless attitude will most likely lead to the ugly shrink on a polyester shirt or other apparel made of it.

  • Another approach is to add iron.

Launder the apparel the same as it was described above.

Instead of a tumble-drying, spread the apparel on the iron board still inside out and cover it with the pressing cloth to protect from burns.

Iron either on low or medium heat regime without steam.

  • Fadeless shrinkage

To protect the colors, add a half cup of white vinegar when laundering. Keep the heat settings to the highest and remember to turn the apparel inside out.

These two options are the most widespread and effective, besides, they’re the less harmful to the fabric.
