Wool materials generally refer to wool fiber fabrics. Wool fibers are made up of protein molecules. They have a unique layer of tight keratinous scale structure on the outside, which is tightly covered. This sheet-like structure is very small. Its advantage is to prevent dirt from penetrated into the fibers, so wool wool clothing is not easy to get dirty.

The reason why wool clothes produce bright light is:

1. The tissue part of the keratinous scale layer on the surface of wool fibers is worn.

2. The dust and dirt rub lightly and stick to the weaving groove, making the surface of the fabric slip, causing the light to refract regularly and bright light to appear.

Methods to remove light from wool clothes:

1. You can twist the bread into powder and spread it on the bright spot, and iron it with an iron.

2. Perform pickling: Soak in a glacial acetic acid aqueous solution with a concentration of 3-5% and a temperature of 50°C for 3-5 minutes, and then rinse it with clean water. White vinegar is also OK.

3. Method of brushing with a brush when washing.
