How to expose to the sun:

1.It is best to choose mild sunlight and avoid drying wool coats at noon or when the sun is strongest.

2.You can hang wool coats in a well-ventilated place but avoid direct sunlight, such as the shade of the balcony or a place near the window indoors but not exposed to direct sunlight.

Time to expose to the sun:

 1. Wool coats can be exposed to the sun moderately, but the time should not be too long. Generally speaking, a short period of sun exposure (such as 1-2 hours) can help remove moisture and odor from clothes, while using the ultraviolet rays in the sun for natural sterilization.

2. Long-term exposure to the sun, especially strong direct sunlight, may damage wool fibers, making the coat fragile, deformable, and even faded.

Precautions:

1.Before sun exposure, make sure the wool coat has been cleaned and dried thoroughly to avoid odor or mold during sun exposure.                                                                             

2. During sun exposure, turn the wool coat regularly to ensure that it is evenly heated to avoid local overheating and fiber damage.
                                                                                                                                                3. After sun exposure, take the wool coat back in time and store it properly to avoid it getting wet again or being exposed to direct sunlight.
