Among all cellulose derivatives, cellulose
acetate butyrate (CAB) shows some superior properties such as high scratch
resistance, and being economical. The high viscosity of CAB in molten state
restricts the processability property of CAB. Besides that, the low thermal
stability of CAB leads a narrow processability range between the melting and
decomposition temperatures. Researches regarding the solution of these problems
are so limited in literature and there is no research considering the
modification of the CAB by using urethane based oligomers (Çakmakçı et al., 2012, El-Sakhawy et al.,
2014, Wang et al., 2017). In this study, in order to eliminate the undesired properties of CAB,
the hydroxyl groups on CAB were partially reacted with toluene diisocyanate-2-hydroxyethyl
methacrylate (TDI-HEMA) adduct with the aim of the formation of carbamate ester
and UV-functional acrylate groups on CAB structure. The chemical modifications
were followed by using FTIR and 1H NMR spectroscopies. Then the
obtained modified oligomer was included in the preparation of UV-coating
formulations on cotton fabrics with water repellent finish. It was aimed to
improve the washing fastness of water repellent finish of cotton fabrics. The
thickness increment stemming from the water repellent finish and UV-coating on
fiber surface was investigated by light microscopy. The water repellency
property of fabrics were evaluated by using spray test (AATCC 22) and
absorbency test (AATCC 79), respectively. The effects of UV-coating on abrasion
resistance of fabrics were also investigated.
