TENCEL™ KUMAŞLARIN SU VE YAĞ İTİCİLİK ÖZELLİKLERİNİN İYİLEŞTİRİLMESİNDE SİKLODEKSTRİN VE ÇAPRAZ BAĞLAYICI ETKİSİNİN İNCELENMESİ.

In this study, it was intended to enhance the water and oil repellency properties of TencelTM fibres that are in naturally hydrophilic character to expand their usage possibilities. For this aim, Tencel™ fabrics were treated by floroalkyloligosiloxan (Dynasylan F 8815), cyclodextrin, crosslinking agent and catalyst. By preparing seven different treatment recipes, fabric application processes were carried out in one or in two stages. Then, the properties of the samples like water and oil repellency values, durability of the treatments after washing, bursting strength, stiffness and yellowness were determined and compared. Moreover, the microscopic images of the samples were evaluated and chemical structure of the fabric surfaces were characterized. The most withstanding outcome was obtained by the two stages application of floroalkyloligosiloxan, cyclodextrin, crosslinking agent and catalyst altogether to Tencel™ fabric surfaces.
