Aumento de la resistencia al drenaje.
Aumento de la resistencia a la tracción, rigidez, estouro,
resistencia interna.
Disminuición de la permeabilidad, bulk, opacidad, coeficiente de
de refracción de la luz.
Blancura disminuye levemente.
Resistencia a rasgaduras:- Fibra larga: aumenta levemente en inicio, después cae.
- Fibra corta: Aumenta significativamente en inicio, después cae.

Valmet IQ Softness Measurement (Suavidad)
Correlates to hand-feel test and lab devices such
as Emtec Tissue Softness Analyzer
Also measures other tissue surface properties
– Crepe count / cm, crepe amplitude and shape
– Known roughness measures
Tissue surface illuminated by RGB lights, each
directed from a different angle
Advanced image processing and modeling of the
captured image reveal softness and other tissue
surface properties
