Final answer:
High-quality fur texture traps air in many small pockets, which reduces convection and leverages the low thermal conductivity of air to provide effective insulation.
Step-by-step explanation:
The texture of fur in the commercial normal fur class is a property that has to do with how the fur feels and is influenced by the characteristics of the fur fibers. Based on the given information, we can infer that a high-quality fur texture would be one that effectively traps air in the fur's structure.
The presence of many small air pockets within the fur leads to slower convection, and thus, better insulation due to air's low conductivity. These air pockets are what make fur a very good lightweight insulator.
The points given in the commercial normal fur class for the category of texture can be related to its insulating properties. Fur is filled with air, which breaks it up into many small pockets. The low conductivity of air makes fur a very good lightweight insulator. This means that fur can trap heat and keep it close to the body, providing warmth.
