Fatma A. Mohamed, Hassan M. Ibrahim, Elham A. El-Kharadly, Ekhlas A. El-Alfy.


Abstract

To improve the dyability and antimicrobial activity of cotton, we treatment the cotton, Firstly, Carboxymethylation was carried out in the cotton fibers to form alkali cellulose. Due to carboxymethylation, the alkali cellulose modifies the crystalline structure of cellulose and increases the accessibility of fibres to chemicals by swelling. Secondly, it padded in a solution content ( 5 % nano zinc oxide,, 4% citric acid) or( 6 % titanium isopropoxid, 4% citric acid) or in a solution of ( 5 % nano zinc oxide, 6 % titanium isopropoxid, 4% citric acid) at wet pick up of ca 100%, then dried at 85 °C for 5 min., and cured at 100 °C for 3 min ,the latter ,we use these fabric in dyeing with synthesized acid dye and commercial basic dye finally, we measure antimicrobial activity for these fabric toward grame negative and grame positive .

Key words: Carboxymethylation, titanium isopropoxid, nano zinc oxide antimicrobial, dyeing, cotton
