Understanding Shrinkage in Fabrics

Fabrics can undergo shrinkage due to several factors such as fiber type, weave, and manufacturing processes. Shrinkage occurs when fabric contracts after exposure to heat, moisture, or mechanical stress during laundering.

Does Polyester Spandex Shrink?

Polyester spandex possesses unique characteristics. While polyester is known for its resistance to shrinkage, spandex, due to its elastic properties, may contribute to a slight shrinkage effect.

The combination of these fibers often results in polyester spandex garments that are less prone to shrinking compared to pure cotton or wool items. However, it’s essential to understand the proper care techniques to minimize any potential shrinkage.

How to Prevent Shrinkage in Polyester Spandex

To maintain the integrity of polyester spandex clothing and minimize shrinkage, it is advisable to follow specific care instructions:

  • Wash garments in cold water to reduce heat exposure.
  • Avoid high heat settings while drying; opt for low heat or air-drying methods.
  • Use fabric softeners or conditioners sparingly to maintain elasticity.

Myths and Misconceptions

There are common misconceptions surrounding the shrinkage of polyester spandex. Some believe that all fabrics shrink uniformly, which isn’t accurate. The blend and manufacturing processes significantly impact shrinkage tendencies.

Comparing Polyester Spandex with Other Fabrics

When compared to natural fabrics like cotton or wool, polyester spandex exhibits lower shrinkage tendencies. Its synthetic composition and elasticity contribute to its ability to retain shape even after repeated washes.

Tips for Care and Maintenance

When it comes to caring for and maintaining polyester spandex garments, there are a few key tips to keep in mind:

  1. Washing Instructions: Always follow the care label instructions on the garment. Typically, it’s recommended to wash polyester spandex in cold water. Avoid using hot water as it can affect the elasticity of the fabric.
  2. Gentle Wash Cycle: Use a gentle or delicate cycle on your washing machine. This helps prevent excessive stress on the fabric, preserving its stretchiness.
  3. Mild Detergent: Opt for mild detergents specifically formulated for delicate fabrics. Harsh detergents can damage the fibers of polyester spandex.
  4. Avoid Bleach and Fabric Softeners: Bleach can deteriorate the fabric, leading to color fading and loss of elasticity. Similarly, while fabric softeners might seem appealing, excessive use can harm the spandex fibers, affecting their stretch.
  5. Air Drying: Whenever possible, air-dry your polyester spandex clothing. Hanging them on a clothesline or laying them flat helps maintain their shape and elasticity. If using a dryer, use a low heat setting to prevent shrinkage.
  6. Storage: Store your polyester spandex garments properly by hanging them or folding them neatly. Avoid overcrowding in the closet to prevent wrinkles and maintain their original shape.
  7. Avoid Sun Exposure: Prolonged exposure to direct sunlight can cause the colors to fade and weaken the fabric’s elasticity. Store garments away from sunlight when not in use.
  8. Ironing: If ironing is necessary, use a low heat setting or iron on the reverse side of the fabric. High heat can damage the spandex fibers.

What happens if you put polyester spandex in dryer?

Putting polyester spandex in a dryer can potentially lead to shrinkage and damage to the fabric.

The high heat in dryers can affect the elasticity of spandex fibers, causing the garment to shrink or lose its shape.

It’s advisable to air-dry polyester spandex clothing or use a low heat setting in the dryer to preserve its stretchiness and quality.

How to shrink a 95% polyester 5% spandex dress down a size?

Shrinking a dress made of 95% polyester and 5% spandex down a size might be challenging due to the fabric’s composition.

Polyester is generally resistant to shrinkage, and spandex adds elasticity, making it less prone to shrinking.

However, washing the dress in hot water and using high heat in the dryer could potentially cause slight shrinkage.

Yet, the results might be limited due to the fabric’s properties. Tailoring or altering the dress might be a more reliable option to achieve a precise size reduction.

How do you wash polyester spandex?

Wash polyester spandex in cold water using a gentle cycle. Use a mild detergent to prevent damage to the fabric.

Avoid hot water and harsh chemicals that can affect its elasticity. Air-drying is preferable, but if using a dryer, opt for a low-heat setting to prevent shrinkage and maintain the garment’s quality.

Does 100% polyester shrink in dryer?

Pure polyester fabrics are generally resistant to shrinking in the dryer due to their synthetic nature.

Polyester has low absorbency and heat resistance, making it less prone to shrinkage compared to natural fibers like cotton or wool.

However, extremely high heat settings in the dryer could potentially cause minimal shrinkage or damage to the fabric over time.


In conclusion, while polyester spandex garments may have minimal shrinkage tendencies compared to natural fibers, proper care is crucial to maintain their longevity and fit.

Understanding the fabric’s composition and implementing appropriate washing and drying techniques can significantly reduce shrinkage effects.
