Do all Alpha Direct fabric products have to be washed by hand?

Put socks in a laundry net, and wash leggings and neck gaiters by hand^[1][2]. The Alpha Direct product category of LITEGEAR HOUSE uses the same fabric family, yet the washing methods differ depending on the item.

Socks are washed using a neutral detergent in water temperatures of 30°C or below and placed in a laundry net^[3][4]. It is a water temperature of 30°C or below. This means you should choose cold or lukewarm water to prevent heat-induced damage to fibers. If you use a laundry net that reduces friction with other laundry, they can be managed relatively safely even through machine washing.

On the other hand, leggings and neck gaiters should avoid the use of washing machines and dryers, be gently hand-washed, and then air-dried in the shade^[5][6]. The specific reason why the care methods for the two items are divided was not stated in official materials. Generally, loosely woven fleece fabrics have difficulty withstanding the strong rotational force of a washing machine, so care by gently kneading by hand tends to be recommended. When squeezing out water as well, it is better to lay them flat to dry in the shade without twisting forcefully to maintain their original shape.
