The five basic symbol groups
Most care-symbol systems are built around five treatment groups: washing, bleaching, drying, ironing and professional cleaning. The washtub covers washing. The triangle covers bleaching. The square covers drying. The iron covers ironing. The circle covers professional textile care such as dry cleaning or wet cleaning.
A good care label reads like a sequence. It tells the customer how to clean the item, how harsh the process can be, how to dry it, whether heat is safe, and whether professional cleaning is allowed. If the item has trims, prints, elastic, interfacing or hand-dyed fabric, the care instructions need to protect the whole item, not only the main fabric.
- Washtub: wash method and temperature.
- Triangle: bleach permission or prohibition.
- Square: tumble or natural drying.
- Iron: ironing temperature.
- Circle: professional cleaning.
Dots, bars and crosses
Dots usually show temperature. More dots mean more heat. In many care symbol guides, one dot is cool or low, two dots are warmer or medium, and three dots are hotter. Washing symbols may also use degrees Celsius or a dot system depending on the market and symbol set.
Bars under a symbol show a milder process. One bar often means permanent press or gentle treatment. Two bars mean very gentle treatment. A cross through a symbol means do not use that treatment, such as do not bleach, do not tumble dry or do not iron.
Washing symbols
The washtub tells the customer whether the item can be machine washed or hand washed, and at what maximum temperature. A hand in the tub means hand wash. A crossed-out tub means do not wash. Temperature may be shown as 30 C, 40 C, 60 C or as dots.
For handmade garments, choose washing instructions based on testing. A sweater may technically survive one machine wash but stretch badly over time. A hand-dyed scarf may bleed unless washed cold and separately. If normal consumer behaviour could damage the item, add plain wording where symbols alone are not enough.
Bleaching and drying symbols
The triangle tells the customer whether bleach can be used. An empty triangle can mean bleach allowed, a triangle with restrictions can mean non-chlorine bleach only, and a crossed triangle means do not bleach. If bleach will damage colour, fibre, elastic or print, do not leave the instruction vague.
Drying symbols can be the most important part of a handmade label. A square with a circle usually means tumble drying, with dots for heat. Natural drying symbols can show line dry, drip dry, dry flat or dry in shade. Wool, crochet and knitwear often need dry flat instructions to prevent stretching.
- Do not bleach if colour or fibre will be harmed.
- Use low tumble heat only if testing supports it.
- Use dry flat for items that can stretch when hung.
Ironing and professional cleaning
The iron symbol controls whether the customer can iron or press the item and at what temperature. One dot is low heat, two dots medium, and three dots high in many systems. A crossed iron means do not iron. Heat-sensitive prints, synthetic lace, sequins and elastic often need caution.
The professional cleaning circle is for dry cleaning and wet cleaning processes. Letters inside the circle relate to solvents or professional methods in specific systems. If a garment cannot be safely washed or dry cleaned, the care label needs clear words such as do not wash and do not dry clean, not a guess.
Symbols are not universal shortcuts
Care symbols are similar across many countries, but not identical in legal status or permitted use. The United States care label rule recognises ASTM care symbols for use in place of words. ISO 3758 is an international symbol standard used in many markets, and GINETEX symbols can involve licensing considerations.
For an indie maker, the safest workflow is to write the care instruction in plain language first, test it, then choose the correct symbol set for the market. Do not copy random icons from a download pack and assume they are legally usable or technically correct.
Frequently asked questions
What are the five laundry symbol groups?
Washing, bleaching, drying, ironing and professional cleaning.
What do bars under a care symbol mean?
Bars usually mean a gentler process. One bar is gentle or permanent press, and two bars are very gentle in many systems.
What does a crossed-out symbol mean?
It means do not use that treatment, such as do not bleach, do not tumble dry or do not iron.
Can I use symbols without words in the United States?
US rules allow specific ASTM care symbols in place of words when the symbols meet the rule requirements. Do not assume every international symbol set is accepted.
Should handmade knitwear say dry flat?
Often yes if hanging would stretch the item. Test the finished fabric and trims before choosing the drying instruction.
