Potential use of new methods for identification of hollow polyester fibres

Today, manufactured textile fibres have many types of chemical structures and finishes and the majority of production processes are new. Therefore, it has been very difficult to identify the different types of fibres in recent times. Even though these fibres may come from a known group of fibres, they do not have the same thermal behaviour, melting point or solubility as classical fibres. So their analysis methods must be more specific than classical fibre analysis methods. The purpose of this study is to investigate various properties of some hollow polyester fibres by new identification methods. For this aim, chemical composition analysis, microscopic analysis, FT-IR and DSC analyses were done. Among these methods, microscopic analyses were found to be most useful in the identification of the hollow PET fibres
