Technical Tool Overview: Breathability Score Calculator
Breathability in textiles is the sum of two distinct physical properties: Air Permeability (the flow of air through the fabric pores) and Vapor Transmission (the passage of sweat molecules through the fibers themselves).
Functional Logic & Architecture
- The Weave Interstices: Breathability is primarily governed by the “holes” (interstices) between the warp and weft yarns.
- Open Mesh (1.4x): Large gaps allow for maximum airflow.
- Satin/Sateen (0.4x): Long “floats” of yarn pack tightly together, significantly reducing the path for air to pass.
- GSM (Thickness) Penalty: Even a highly porous weave will lose breathability if the yarns are thick. As GSM increases, the length of the “tunnel” air must travel through increases, creating more friction and lower flow rates.
- Finishing & Barriers: Treatments like lamination or heavy starching “plug” the pores of the fabric. The calculator applies a massive penalty (up to 70%) for waterproof coatings, as they prioritize liquid protection over air flow.
Features & Capabilities
- Sleek 4px UI: Dense input fields allow for professional use in textile labs or retail design rooms.
- Porosity Index: Translates complex physics into a 0-100 scale that is easy for marketing teams to communicate.
- Finishing Logic: Accounts for chemical treatments that are often ignored in basic weight-based calculations.
Industry Use Cases
- Product Development: Used by Rangeen Jora to ensure their “Summer Breeze” collection meets a minimum breathability score of 85.
- Software Integration: DIHOD Software House can integrate this logic into e-commerce filters, allowing users to “Sort by Breathability.”
- Comparative Analysis: Helps buyers understand why a 100 GSM Linen shirt (High Score) feels cooler than a 100 GSM Polyester shirt (Low Score).
