There are finer varieties of polyester like microfiber we cannot even see with our naked eyes.

1. Polyethylene terephthalate (PET)
2. Polybutylene terephthalate (PBT)
3. Polylactic acid (PLA)
4. Polytrimethylene terephthalate (PTT)
5. Polyethylene naphthalate (PEN)

Polyester has many types tailored for specific fabric applications and properties. Understanding the options allows for proper selection based on your project needs.

Rayon Vs Polyester: Comparison Table

When considering which fabric to choose for your clothing, it’s important to compare the warmth, breathability, climate suitability, durability, and potential shrinking of both rayon and polyester. By understanding these key points, you can make an informed decision on which fabric will best suit your needs.

The breathability and climate suitability of rayon and polyester differ. Polyester does not absorb moisture well, so it can feel hot and clammy in warm weather. Rayon absorbs moisture better, keeping the wearer cooler in summer. However, rayon may not retain warmth as well as polyester in cold weather.

Both fabrics are reasonably durable with polyester being the more resilient of the two. Rayon can shrink significantly unless pre-washed, whereas polyester is generallyshrink-resistant. Taking these factors into account allows you to select the most suitable fabric for the climate and intended use.

Warmth

You’ll shiver less in polyester when the weather gets nippy. The insulating properties of polyester retain warmth better than rayon does. This makes polyester the ideal choice for cold weather clothing, outerwear, and layering pieces.

Polyester	Rayon
Insulates heat	Poor insulator
Keeps you warm	Feels cool against skin
Ideal for winter wear	Prefers warmer climates
Traps body heat	Allows heat to escape

Polyester is the clear winner for retaining warmth compared to rayon due to its superior insulating properties, which help you stay toasty when the mercury dips.

Breathability

You can’t beat rayon’s breathability and moisture absorption compared to polyester’s lack of breathability and moisture resistance.

1. Rayon absorbs moisture and allows airflow.
2. Polyester resists moisture and heat builds up within the fabric.
3. The breathable nature of rayon provides cooling comfort.
4. The non-breathable characteristics of polyester lead to sweatiness for the wearer.

Rayon’s superior breathability makes it an ideal choice for clothing to be worn in warmer weather conditions. Polyester is often preferred for cold weather gear, where heat retention is a desirable quality.

It’s best to choose the fabric that matches the environmental conditions you’ll be in.

Climate

Since rayon feels cooler against the skin, it is better suited for warmer climates than polyester.

	Rayon	Polyester
Climate Suitability	Warmer climates	Colder environments
Moisture Absorption	Absorbs moisture	Repels moisture
Breathability	More breathable	Less breathable

Rayon’s breathability makes it ideal for hot and humid weather, while polyester resists moisture better, so it is better for colder climates.

Durability

When choosing between rayon and polyester threads, notice that polyester’s durable nature allows it to outlast rayon’s tendency to wrinkle easily. Polyester withstands repeated use and laundering much better than rayon does, with rayon prone to shrinking, pilling, and wrinkling from normal wear and tear.

Assess polyester’s superior strength and durability if longevity is a key factor for your project.

Shrinking

As you’re comparing these fabrics, polyester resists shrinkage better than rayon due to its durable synthetic construction.

1. Rayon shrinks more in hot water.
2. Wash rayon in cold water.
3. Hang or flat dry rayon garments.
4. Pre-shrink rayon before sewing.
5. Polyester’s molecular structure resists shrinking forces.

The strong intermolecular bonds in polyester’s polymer chains help it maintain its shape and size after laundering, while rayon’s cellulosic fibers are more susceptible to shrinking when exposed to heat and moisture during washing.

When working with rayon, take care to wash in cooler water and line dry to help prevent excessive shrinkage.
