Understanding GSM Variance in Medical Grade Fabrics

Understanding GSM Variance in Medical Grade Fabrics

Industry Standards

Medical fabrics are categorized by AAMI (Association for the Advancement of Medical Instrumentation) levels based on their barrier performance. Level 4 protection requires zero strikes at high pressure, a feat only achievable through extreme GSM uniformity.

Manufacturing Precision

Jayashree Spunbond utilizes multi-beam Reicofil-style extrusion to ensure that filament distribution remains uniform even at high line speeds. Our real-time GSM monitoring systems detect and reject any sections that deviate by more than 0.5 GSM from the target weight.
