Textile damage

New catalysts that enable the fixation of finishes, for example flame retardants or easy-care finishes, in a broader range of parameters - like temperature, time and pH value - help to avoid mistakes and textile damage. A simple method of reducing the possibilities of production mistakes is the incorporation of catalysts and other compounds in the main product, with the positive side effect for the finish producer that no competitive products are used. 

Thermomechanical analysis (TMA) investigates the changes in the dimensions of a sample as a function of the temperature, for example shrinkage or extension of fibres." It is easier to work here with filaments than with staple fibres. Fibre composites and other materials are also analysed by dynamic loading. This dynamic mechanical analysis (DMA) enables, for example, the glass temperature of elastomers to be determined exactly. But in textile damage analysis TMA is seldom used. 

In conclusion the most important advantages and disadvantages of thermoanaly tic methods, both in general and in textile damage analysis, can be summarized ...
