What does polyester really mean?

What does polyester really mean?

Have you ever looked at the tags on your clothing and wondered what exactly those fibers are? Below we break down some of the most commonly found fabrics so you have a better idea of what they are and how they’re made!

Organic fabrics:

Cotton: These fibers grow around the seeds of cotton plants in fluffy puffs meant to aid with seed dispersal. Cotton plants are native to tropical and sub-tropical regions, but have been domesticated elsewhere, including the United States, which remains the world’s largest exporter of cotton goods. It can be used to make terrycloth, denim, corduroy, twill, jersey material, coffee filters, bookbinding, tends, and more.

Silk: Silk is a protein fiber that is woven to create fabric we use, most commonly cultivated from the cocoons of the mulberry silkworm. Silk fibers have a prism-like configuration that refracts light, making the fabric look shiny. Silk fibers have been cultivated for fabric for thousands of years, the earliest examples found in China and dating far back as 3500 BCE.

Synthetic fabrics

Polyester: While there are many different kinds of polyester, the kind found in fabrics usually refers to ‘polyethylene terephthalate’ (PET), a polymer resin used not only in fabric but also in beverage and food containers. It is a combination of both natural and man-made materials. With fabrics, polyester can be woven into thread or yarn, and makes an excellent insulator for carpets, pillows, and upholstery. It can be used alone or blended with other fibers, like cotton.

Nylon: Nylon is a kind of polyamide (polymers made of chemical compounds), and is often used to imitate silk. It’s found not only in pantyhose, but also rope and outdoor clothing. During World War II, nylon was used in the place of silk for parachutes, flak jackets, and tires.

Spandex or Lycra: Known for its elasticity, spandex was invented in 1959 and is an anagram of the word “expands.” It is made up of several different polymers and chemicals that are spun into long, thin threads. In clothing, it is usually blended with cotton or polyester in small amounts to encourage elasticity with a snug fit.

Acrylic: These fibers are made from a lightweight polymer meant to imitate wool or cashmere, and is hypoallergenic. While warm and soft, the fibers are susceptible to static and pilling. You can find them in sweaters, socks, hats, gloves, and scarves. It is very washable and retains color well.

Other fibers:

Rayon: Rayon is neither synthetic nor organic, as it is taken from naturally occurring plants, but then reprocessed into fibers by use of chemicals. It usually has a bright sheen, and so is often used in scarves, suits, lingerie, dresses, upholstery, yarn, and more.

I'd love to see an expansion on this article - How to wash differnt types of fabric!  We all know cotton, polyester, rayon and wool behave differently in the wash.  Maybe we should have a follow-up article about the rules of thumb governing when and why to hand wash versus dry clean versus machine wash.  I think that would be VERY illuminating!

I am always interested in finding detailed information about the things we use!

I agree with Jackie for agreeing with Nina lol! In general, I do really good with our laundry, but when I go out of town or am unable to do the laundry and the hubbs takes over, it would be great to have a basic list from someone else (so he doesn't think I am being picky and making it up lol).

And I agree with all that agree :)  It would be some nice extra info we all could use.

Kinda makes you wonder what you are in fact wearing and if it is harmful or not...when it is made with chemicals.http://munchtalk.blogspot.com

Does anyone know if there is still such a fabric as what we used to call "percale"? Those were the smooth, cold feeling sheets that we had in the late 60's to 70's. All the sheets now become sweaty after a couple of hours and the pillowcases no longer have cool spots when you turn over.

Very informative article. Weird that fabric and plastic storage containers are made of similar materials!

Thanks for this, I never was sure what the composition of fabrics are ... That said, an expanded article would be great, I know that there are different types of silk, some can be machine-washed, others cannot.  The same for wool, which, btw, I always thought was organic ... It would also be helpful to discuss other kinds of fabrics that come from animals, e.g. leather, suede, and other skins.  I'm also finding confusing winter fabrics; e.g., the term "sherpa" - I always thought that sherpa was a person - a mountain guide!  I didn't realize it can also mean a type of fabric ... also cashmere, shearling, angora, etc. This would have been extremely helpful 20 years ago, my youngest dd was dx'd with eczema when she was a newborn, and I learned (the hard way) that most synthetic fabrics irritate her skin.

And plastic bags, shoes, toothbrushes, bottles/jars ... the list goes on.  It's very difficult to avoid plastics in our lives!

Isn't percale just a particular weave of cotton?  That's what I always thought ...

This is great information - thanks for the details. Hopefully I am not the only one to ever do this but I laundered a rayon outfit years ago just so I could see exactly why it was "dry clean only". Now, if the label says "dry clean only", by golly, I obey!    :/

I believe that "percale" is juat a tightly woven cotton sheet
. It's usually the synthetic materials that don't breathe and so make you feel sweaty. All cotton sheets will be more wrinkly, but that would be okay with me if I wanted the cool feel of all cotton.

I like Beth's question about getting a clarification of what percale is? But my greater concern is the use of all these chemicals to create fabrics used for everything from undergarments to bedding and the effects on our health considering the recent concern with harmful BPA's in reuseable plastic containers. It would be helpful to have a part two which  explores those issues.

I noticed lately there are not as much cotton clothing as in years past. It seems polyester has been a booming industry lately. The problem with an all polyester product in my opinion is that it is more silky, wears very well but does not release moisture/sweat as well as cotton does. The only problem I have with 100% cotton is the ironing! Otherwise cotton would be my first choice overall. I do tend to purchase clothing with half polyester and cotton. Seems to make a great combination.
