Often the fabrics used for textile architecture are exposed to inclement weather which leads the yarns to absorb a great deal of humidity, facilitating the formation of moulds. For this reason polyester yarns with high tenacity benefit from the "Low Wick". anti-capillary treatment.
This treatment, applied during the production of the yarns in the integrated spinning mill, allows absorption of humidity in the fibres to be limited, in particular on the side exposed to sealing.
This leads to an improved appearance of the membranes in transparency.
