註釋In this research was studied the use of an unsaturated bifunctional acid (maleic acid) and a phosphorus-containing inorganic compound (sodium hydroxyphosphinite) to obtain additional functionality of cotton fabric. First reaction mechanism of maleic acid (MA) and sodium hydroxyphosphinite (SHP) was investigated in solid state at elevated temperature; further the crosslinking of MA and additional reaction of SHP on double bond of MA linked to cotton was studied Chemical reactions between MA and SHP where investigatedby using of FT-Raman and ATR FT-IR spectroscopy. The influence of time, temperature and molar ratio of MA and SHP of prepared mixtures in solid state on the reaction mechanism was investigated. MA/SHP system has potential flame retardant and durable press functions when applied to cotton cellulose. The esterification mechanism of MA to hydroxyl groups of cellulose and addition of SHP to C=C was investigated by ATR FT-IR and FT-Raman spectroscopy. The phosphorus content on treated cotton fabrics was measured by ICP atomic emission spectroscopy. The final results of MA/SHP system crosslinked to hydroxyl groups of cellulose was evaluated by WRA. It was shown that MA/SHP system could be used as potential flame retardant system because it contains phosphor; at the same time in such way treated textile material has durable press finishing properties.
