Abstract
The heat of wetting of regenerated cellulosic fibres (TENCEL (R), Viscose and Modal) was investigated by reaction calorimetry in comparison with cotton, polyester and TENCEL (R) Fabric. Reaction calorimetry is a technique applied for measuring the heat evolved in chemical reactions where very high analytical precision is required Before the measurements, the fibre samples were dried in an oven at 80 degrees C for 60 min with a low and constant nitrogen flow to eliminate initial moisture. As final results the amount of heat in Joules per gram fibre is given. The experimental results showed that the highest heat of wetting was measured for man-made cellulosic fibres, middle for cotton, while the lowest heat of wetting was observed for... (More)
The heat of wetting of regenerated cellulosic fibres (TENCEL (R), Viscose and Modal) was investigated by reaction calorimetry in comparison with cotton, polyester and TENCEL (R) Fabric. Reaction calorimetry is a technique applied for measuring the heat evolved in chemical reactions where very high analytical precision is required Before the measurements, the fibre samples were dried in an oven at 80 degrees C for 60 min with a low and constant nitrogen flow to eliminate initial moisture. As final results the amount of heat in Joules per gram fibre is given. The experimental results showed that the highest heat of wetting was measured for man-made cellulosic fibres, middle for cotton, while the lowest heat of wetting was observed for polyester fibres. The heat of wetting depends on the interaction of water with hydroxyl groups in the non-crystalline domains of the fibre. Finally, the results of the heat of wetting obtained by modern reaction calorimetry were compared with results obtained using a self-constructed solution calorimeter as well as with data reported in earlier studies.
