Abstract:

In order to develop the plant polyphenol gralth functional textiles, the influences of pH value, temperature, treatment time on adsorption amount of tea polyphenols on cotton fabric were discussed by the single factor analysis method. The cotton fabrics were cationised. The influences of modifier and alkaline agent dosage, modification temperature and time on adsorption amount of tea polyphenols on cotton fabric were analyzed. Antibacterial and deodorant performances of the cotton fabrics treated by tea polyphenols were tested. The results showed that adsorption rate of tea polyphenols on cotton fabric was 14.6% when the cotton fabric was impregnated in 6% (o. w. f) tea polyphenols solution at 40℃ for 60min with bath ratio 1:30. Cationic modification process of cotton fabric were as follows: modified agent concentration 25g/L, alkali concentration 6g/L, temperature 70℃, time 90min and bath ratio 1:30. The adsorption rate of tea polyphenols on the modified cotton fabric was 48.8%. The results of deodorizing and antibacterial tests indicate that the modified cotton fabric treated by tea polyphenols has 92.2% antibacterial activity agaist staphylococcus aureus and 90% deodorizing activity on ammonia. The modified cotton fabric treated with tea polyphenols followed by copper sulphate has 100% antibacterial activity on staphylococcus aureus and 99.9% deodorizing activity agaist ammonia.

Key words: tea polyphenols, cotton fabric, cationic modification, antibacterial, dedodorizing
