Thesis (M.Sc.)--Chulalongkorn University, 2004

The modified chitosan was prepared by the reaction of chitosan (molecular weight = 10[superscript 5] and 10[superscript 6]) with phthalic anhydride using the chitosan : phthalic anhydride mole ratio of 1 : 12 and 1: 18. Characterizations of the produced phthaloyl chitosan by FTIR and [superscript 1]H NMR confirmed the successful reaction as evidenced by the presence of carbonyl amide band (1640 cm[superscript -1]), the decrease in NH[subscript 2] band due to its conversion, and the NMR signal of the aromatic ring at 7-8 ppm, respectively. As a result of introduction of the phthaloyl moiety, the modified chitosan was expected to become both hydrophobically and hydrophilically. Furthermore, this group is resemble to the poly(ethylene terephthalate) (PET) aromatic segment, making the modified chitosan suitable for surface coating of PET fabric. After that, the obtained phthaloyl chitosan was applied onto PET fabric using a pad mangle to obtain 80% of wetpick up and was thermofixed in a mini stenter at the temperature between 180-200C for 3 minutes. The finished polyester fabrics were subjected to an evaluation of moisture regain, wettability, as well as surface examination using scanning electron microscopy (SEM). From SEM evidence, the pththaloyl chitosan could exhibit better adhesion performance when compared to the unmodified chitosan finished polyester. This confirmed that the phthaloyl moiety of the modified chitosan played the determined role in controlling the adhesion ability of the phthaloyl chitosan. Wettability test showed that wetness of treated fabric with modified chitosan improved significantly when compared to untreated polyester fabric and treated polyester fabric with unmodified chitosan. It was found that using phthaloyl chitosan (prepared with the mole ratio of chitosan (M[subscript w]=10[superscript 6]):phthalic anhydride 1:18) with the concentration of 9 g/l and curing temperature at 190C for 3 minutes was the optimum condition for hydrophilic finishing of polyester fabric in this experiment
