At what temperature does polyester shrink? (2024)

What temperature does polyester shrink?

Polyesters can resist shrinking up to a great extent, but. High heat with 140 degrees Fahrenheit minimum temperature can shrink the 100% polyester fabrics. You need to be very careful while setting the heat for your washer, dryer as well as iron to shrink your Polyester material.

Yes, 100% polyester shrinks but in some circ*mstances because it resists shrinkage by nature. Polyester is resistant to shrinkage but if you wash polyester with hot water or if you iron polyester with excessive heat iron, it can cause shrinkage as it is a man-made fabric that is made with polymer.

Synthetic fibres such as nylon and polyester should not shrink at 40 degrees Celsius.

Polyester does not shrink in a warm washing machine cycle, and it can safely go in a normal dryer setting as well. However, soaking polyester in hot water or leaving it in the dryer for an extended period may cause the fabric to shrink or warp. Polyester blends shrink more easily than 100% polyester.

To try to shrink, wash the garment at the hottest water setting of your washing machine (only this garment, nothing else). After washing, place the garment inside a garment laundry bag or tied pillowcase and tumble in the dryer at its hottest setting for 10 minutes. Remove and try the garment on; if it fits, great.

You can shrink it in the washing machine or the dryer. The key to shrinking polyester fabric is to use heat. You do not need to use detergent or fabric softener while shrinking polyester.

Using Boiling Water

For noticeable shrinkage to occur in polyester clothes when wet, place the clothes in boiling water. The heat of the water breaks down the fibers slightly, causing them to shrink. More shrinkage occurs with polyester and natural fiber blends than with 100-percent polyester.

Your polyester fabrics will not shrink in the washer unless under extreme conditions. Your polyester clothes should come out just fine if you use cool or lukewarm machine cycles. However, your polyester might have a small shrinkage if you use hot water. The safest temperatures to wash polyester are those below 230F.

Polyester is heat sensitive: High temperatures can cause it to melt, shrink, or deform. Never select hot water or high-heat settings when using the washer, dryer, or iron.

30°C washes softer fabrics better than 40°C, which is why 40° is better for your everyday clothing, and fabrics that are harder e.g. wool. This is the temperature that most consumer testing boards use to measure the performance of the machine. materials at 40°C and the results will be just as good.

Polyester Care

However, if you wash your polyester in the washing machine, avoid using the heavy-duty cycle. This cycle spins very fast, causing the fibers to stretch.

Spandex/Polyester

Polyester is more heat resistant than spandex, so it won't shrink as easily in the wash as a pure spandex garment. The polyester can help reduce spandex shrinkage when you blend the two, but it won't prevent it entirely.

Washing at 60 – 90°C

The 90 degrees program can only be used for cotton and linen but then again, clothing labels won't recommend using that kind of high temperature.

Use the permanent press setting for its medium heat or hang dry. Polyester is subject to static cling, as it rubs against other clothes in the dryer, so using a Bounce® dryer sheet is a good idea. Avoid overheating because that causes polyester fibers to ripple and can damage the clothes over time.
