IMPACT OF SINNER CYCLE WASHING PARAMETERS ON THERMAL CHARACTERISTICS AND APPEARANCE OF PROBAN® FLAME RETARDANT MATERIAL

Proban® is multiphase treatment of cotton fabrics based on the formation of pre-condensates using a flame retardant (FR) agent based on tetrakis(hydroxymethyl)phosphonium salts (THPx). The assessment of the durability of a product demand the preliminary understanding of how relevant is to extend its lifetime. Changes in surface properties and pore volume are the main causes of the change in material properties. It is therefore important to minimise the risk of agents acting on: (1) protection level, (2) shape and dimensions and (3) additional comfort characteristics. This research focused on impact of washing conditions on the durability of FR properties and appearance of Proban cotton fabrics was systematically organized through variation in chemistry distribution in Sinner cycle. The chemical share is varied in laboratory conditions as simulation of industrial washing based on component dosing where temperature, time and mechanical agitation were constant. Washing of cotton fabrics was performed through 10 cycles in four baths containing high alkali components, medium alkali components, high alkali reference detergent and water. The limited oxygen index (LOI), calorimetric parameters (Micro Cone Calorimetry), thermal analysis (TGA-FTIR), surface examination (SEM), spectral characteristics and pH of an aqueous extract of fabrics before and after 10 washing cycles were selected for proof of the concept. Proof of a medium alkali bath as a washing concept for Proban cotton fabric is approved through preservation of FR properties examined through LOI, TGA and MCC parameters and appearance - color and low level of fibrillation.
