Dry Your Laundry

The best time to put away your laundry would be in the afternoon, when it is usually the warmest. At a higher temperature, air can hold more moisture (Watch video on Humidity). This is why the same air can hold more moisture in the afternoon than in the morning.

If you do leave you laundry till the morning, RH of the air increases as the air is cooler and can hold less moisture. Some of the moisture may condense from the air back onto your clothes. Have you ever noticed the clothes in the morning may feel a little cool/damp?

  • (a) Odour:
    During drying, the tumbler dryer has to heat up the air internally to about 60℃. When the tumbler dryer stops, the air inside cools down and some moisture will condense back onto your clothes. At this point, when you put away your clothes, bacteria will be able to grow even with this little amount of moisture. That is why sometimes your laundry might smell even after washing and drying with the tumbler dryer.

  • (b) High Electrical Cost:
    Why does the tumbler dryer need to operate at such high temperatures? At higher temperature, water from the clothes evaporate faster as the moisture holding capacity of the air has increased (Watch video on Humidity). But heating air to such high temperatures during the drying cycles takes quite a bit of energy.

  • (c) Fabric Disintegration, Shrinkage, Discolouration:
    Ever wonder where all the lint from your tumbler dryer comes from? That’s right! It comes from the clothes you placed inside the dryer. Lint is tiny bits of fibers that are shed from our garment from the tumbling action of the dryer. Tumblers also can shrink fabric due to the high temperature in the dryer.

In general, the clothes after wash will weigh about 30-60% MORE because of the absorbed water. For example, if you wash 8kg of laundry, you will get 2.4kg to 4.8kg of water absorbed by your laundry after wash. How much water weight the laundry retain will depend on the spin cycles of your washing machines and the types of fabric. A higher spin cycle above 1200rpm will result in less water weight. A lower spin cycle will result in more water retention on the clothes. Jeans and cotton will retain more water than polyester. When you use the Secomat Laundry Dryer, the water will evaporate from your clothes into the air. The dryer will dehumidify the air and the water can be collected in a bucket.

This water is actually quite usable – here are a few suggestions! (How clean is the water collected from the dehumidifier?).

When the RH is close to 100% (rainy days or early in the mornings), the air is holding close to maximum amount moisture. No matter how you blow and heat up the clothes, the air cannot hold any more moisture, still leaving your laundry damp. To help water evaporate from the laundry, moisture would first need to be removed from the air. Kruger Laundry Dryer does exactly that.
