What Are the Key Performance Properties of Sailcloth Canvas?
Specific properties determine the performance of sailcloth canvas. Tensile strength, measured in pounds per inch (lb/in) or Newtons per meter (N/m), shows the fabric's resistance to breaking under tension. It is usually tested using methods such as ASTM D5034 or ISO 13934-1. Tear strength, measured in pounds (lb) or Newtons (N), shows how well a material resists tearing. It is usually tested using methods such as ASTM D2261 or ISO 13937, separately for warp and weft directions. Water resistance is often quantified by a hydrostatic head measurement, typically in millimeters (mm). This indicates the pressure at which water starts to penetrate through the material. UV resistance is measured with an Ultraviolet Protection Factor (UPF) rating. Abrasion resistance is measured by the number of cycles using tests like Martindale or Wyzenbeek. Dimensional stability is determined by the shrinkage percentage after washing or heat exposure, which shows how much the material contracts or shrinks. Breathability is determined by the air permeability (measured as cubic feet per minute or cubic meters per second). Stiffness is measured by the bending modulus. These measurements allow the material to be categorized according to its performance and suitability. I have learned through years of experience, that understanding these is crucial for picking the correct material. These metrics are important to be considered for the end application.
