A shirt of 60% cotton, 37% polyester and 3% elastane leaves you guessing which fiber to treat it as. Enter each fiber name and share along with the limits you read off the care label, and the tool keeps only the strictest of those limits, then checks whether the ironing dots and the washing you planned stay inside them.
The rule is simple: the iron dot cap for the whole garment is the lowest of the caps you entered, and washing counts as not met if any single fiber is marked not allowed. Anything left as unknown is dropped from the verdict and counted separately. Because the International Association for Textile Care Labeling states that the maximum temperature must be chosen only from the care label rather than the fiber composition, this page builds no fabric-to-temperature table and uses only the values you read from the label (as of October 2026).
No authoritative recommended temperature or time per fabric is offered here. Wash temperature, time and the ironing cap all come from the product label. Detergent dosing, spin speed and tumble drying are not covered, and the blend shares are used only to total them up and to show which fiber set the limit. Follow the label and the manufacturer guidance first.
Frequently Asked Questions
No. The strictest limit applies to the whole garment, so a fiber with a 3% share can set the cap. The tool points it out whenever the fiber that set the cap is not the one with the largest share.
Because the International Association for Textile Care Labeling states that the maximum temperature must be chosen only from the care label, not from the fiber composition. A fabric-based table could contradict the label, so none is offered.
They are dropped from the verdict and the count of dropped items is shown in the result. If every limit is unknown, there is nothing to check against and a message says so.
