Water column
The water column is a unit of measurement that gauges the water pressure a fabric can withstand before it becomes impermeable. It is commonly used to assess the waterproofness of textiles.
Characteristics:
The water column is a numerical representation of a fabric's water resistance. The higher the water column, the more waterproof the material.
Application:
The water column is used in the textile industry to evaluate the waterproofness of fabrics, tents, tarpaulins, and clothing.
Determination of the Reference Value:
The water column is measured in millimeters, and the reference value for waterproof clothing is often set at 1,500 mm or higher.
When is clothing considered waterproof?
Clothing is typically considered waterproof when it has a water column rating of at least 1,500 mm.
