What do the dots in tumble dry symbols mean?

Dots inside the circle in a tumble dry symbol indicate heat level: one dot = low heat (approximately 55°C), two dots = medium heat (approximately 65°C), three dots = high heat (80°C+). No dots or an open inner circle indicates no heat (air fluff only). You can always use a lower heat setting than the symbol allows.

What is the difference between line dry and dry flat?

Line dry means hang the item on a line, airer, or hanger to air dry vertically. Dry flat means lay it horizontally on a flat surface. Dry flat is required for knitwear, cashmere, and other heavy fabrics that stretch permanently under their own wet weight when hung.

Can I air dry something that says tumble dry?

Yes — air drying is always gentler than tumble drying. If you prefer to air dry a tumble-dry-rated item, you can line dry or dry flat without any damage risk. The tumble dry symbol gives permission to machine dry; it is not an instruction to do so.

What does "dry in shade" mean?

Dry in shade means keep the item away from direct sunlight while drying, as UV radiation bleaches dyes over time. Dry indoors, in a covered area, or on the shaded side of a building. This is especially important for dark, vivid, and bright colours.

Quick Answer

Tumble dry on permanent press cycle (medium heat with line)

Detailed explanation

The tumble dry permanent press symbol (a square with a circle, two dots, and often a bar) indicates drying at medium heat with the permanent press cycle — which includes a cool-down period at the end of the cycle. This cool-down phase allows synthetic fibres to relax gradually as the drum slows and the heat dissipates, significantly reducing the creasing and static that occur when hot synthetic garments are removed abruptly from the dryer. This is the most important dryer setting for polyester, polyester-cotton blends, and "easy care" garments.

How to follow the Tumble Dry Permanent Press symbol:

1
Set dryer to permanent press cycle
2
Medium heat with cool-down period
3
Reduces wrinkles during drying
4
Remove promptly when cycle ends

When does this symbol appear on care labels?

For polyester shirts, blouses, trousers, and synthetic dress garments
For polyester-cotton blended everyday wear and work clothing
For wrinkle-resistant or "easy care" synthetic garments
For any garment where reducing ironing effort is a priority

Tips and Best Practices

Select the "Permanent Press" or "Wrinkle Guard" cycle on your dryer — the cool-down phase is built into this programme and is essential
Remove items immediately when the cycle ends — the cool-down reduces creasing but items will still crease if left in the drum
Hang garments immediately rather than folding — this sets them in their correct shape
Do not overload the drum — garments need room to tumble freely; crowding prevents the cool-down phase from working effectively
Avoid overdrying — slightly damp is better than bone-dry for synthetic fabrics; overdrying increases static and makes wrinkles worse

What happens if this symbol is ignored

Using a standard high-heat cycle without the cool-down phase on permanent-press items causes heavy creasing and static that defeats the purpose of a wrinkle-resistant fabric. Using high heat (instead of medium) will cause shrinkage and fibre damage.

Common mistakes to avoid

Forgetting to select the permanent press cycle and using the standard medium or high heat cycle instead — the cool-down phase is what makes the difference
Leaving items in the dryer after the cycle ends — even the permanent press cool-down cannot overcome the creasing caused by sitting in a heap
Overdrying synthetic fabrics — stopping slightly early and hanging immediately gives the best results
