Does Cotton Shrink in the Dryer?

Have you ever struggled to get into a shirt that used to fit perfectly, only to find that the cotton has shrunk in the dryer after washing? You’ll got it. Proper garment care is crucial to ensuring the longevity of your clothing, especially when it comes to cotton.

It’s important to understand that cotton fibres can shrink by up to 3% due to the stretching process used to spin them into threads, and the heat from washing or drying can cause this shrinkage.

Fear not, as not all cotton garments will shrink. Many manufacturers pre-shrink clothes to prevent this issue. Throughout this article, you will discover the reasons behind cotton shrinkage and learn valuable tips on preventing unwanted shrinkage while caring for your absorbent towels, comfortable t-shirts, breathable sheets, and more.

What Causes Clothes to Shrink?

Your clothes may shrink due to heat and moisture. This is especially true when dealing with natural, plant-based fibers like cotton and silk. Warm water or steamy air can release tension in threads, causing them to contract. This happens because the fibers are pulled taut during the twisting process to create yarns, and heat relaxes that tension.

However, synthetic fabrics like polyester are less prone to shrinking, as their fibers are often heat-set during manufacturing. Overall, natural materials that can absorb water are more impacted by washing and drying processes, leading to potential shrinkage in your clothes.

Does Cotton Shrink In the Wash?

Cotton may shrink with every wash if exposed to hot water or high dryer heat settings, usually experiencing the most significant shrinkage during the first wash. By purchasing pre-shrunk clothes and adhering to proper washing care, you can avoid additional shrinking.

Do Cotton Blends Shrink in the Wash?

Cotton blend shrinkage depends on the type of fibers combined. For example:

  • Poly-Cotton (50% polyester, 50% cotton) is resistant to shrinking due to polyester’s synthetic nature.
  • 60% cotton and 40% polyester blends don’t shrink easily even in hot water.
  • Triblend fabrics (cotton, polyester, and rayon) may have minimal shrinkage, with polyester preventing significant reduction.
  • Cotton-rayon blends can shrink more than 100% cotton when exposed to high heat.

How to Wash 100% Cotton Items Correctly

To wash 100% cotton items without damage, follow these steps:

  1. Check the care label: Always read the care label as some items might need dry cleaning.
  2. Use cold water: Wash your cotton items in cold water to prevent shrinkage.
  3. Choose a delicate cycle: Set your washing machine to a delicate cycle, or wash the items by hand.
  4. Air dry: Allow your cotton garments to air dry rather than using a dryer.

Does Cotton Shrink in the Dryer?

Dryers can cause cotton to shrink considerably due to the heat and friction generated inside. Typically, you should avoid exposing all-cotton garments to high heat. The swift temperature change and quick drying in a dryer can result in more shrinkage than just washing the material in hot water.

Predicting the exact amount of shrinkage for a cotton shirt placed in a dryer can be challenging. However, if it’s made of preshrunk cotton, it shouldn’t shrink too much, with a possible maximum of 3%. After the first wash and dry, cotton clothes, especially those that are preshrunk or treated against wrinkles, might not shrink the next time.

Avoid putting untreated cotton in the dryer. Cotton fibers can relax at temperatures above 85℉. To keep cotton garments in their original shape, partially dry your laundry and hang it up while slightly damp so it can air-dry.

Interestingly, the dryer’s heat can even shrink cotton clothes if you place them in while already dry!

Cotton blends respond differently to drying. Blends with a significant polyester content handle the dryer well, resulting in minimal shrinkage. In contrast, a blend with higher cotton content, such as 95% cotton, will likely shrink under high heat like pure cotton.

Different types of cotton, like Pima cotton, which is known for its extra-long fibers and softness, also shrink similar to regular cotton after the first wash. To preserve garments made of Pima cotton, manufacturers recommend air-drying or using a low heat setting on your dryer.

Concluding Thoughts on Cotton Care

Keeping your clothes intact and avoiding laundry mistakes is crucial, especially when it involves quality cotton pieces. By understanding how cotton fibers react to heat, you can prevent excessive shrinkage. Remember that preshrunk cotton garments might still shrink 2% to 3% in hot water washes, while untreated ones may shrink up to 20%.

To maintain the original size and vibrancy of the dyes in your cotton items, always wash them in cool water and air dry when possible. If you’ve ever unintentionally shrunk a cotton garment, share your experience and any success in restoring it to its original size.

What causes clothes, especially cotton, to shrink?

Heat and moisture can both cause clothing to shrink. Clothes made of natural plant-based fibers, such as cotton and silk, shrink when warm water or steamy air releases some tension in the individual threads. The process used to twist cotton fibers into yarns pulls the fibers taunt, and heat relaxes some of that tension, causing the fibers to contract.

How can I prevent cotton from shrinking in the dryer?

To prevent cotton from shrinking in the dryer, it is best to avoid exposing it to heat. Use cool water when washing cotton garments and allow them to drip dry instead of using a high-heat dryer setting. Washing clothes made of cotton in hot water will likely cause continued shrinkage during each wash.
