The hairdressing brush is a commonly used tool in the hairdressing industry. A good hairdressing brush can help us quickly create a fluffy shape. For hairdressing brush nylon filaments, it can continue to work under high temperature and hot air conditions, and its high-temperature resistance performance is one of the critical indicators.

Nylon filament is one of the plastic filaments with a higher melting point and thermal deformation temperature. Among them, PA66 and PA46 have the best high-temperature resistance and are one of the most commonly used materials for making hairdressing brush nylon filaments. The maximum short-term use temperature of PA66 nylon filament is 180 ℃, and the maximum continuous use temperature is 120 ℃; the maximum short-term use temperature of PA46 nylon filament is 200 ℃, and the maximum ongoing use temperature is 150 ℃. The two nylon filaments also have excellent bending recovery, they can recover quickly, with moderate softness and hardness; they cannot easily damage the scalp, they can massage the scalp, the filament body is smooth and flat, and they are not easy to strain the hair.
