Study on Quantitative Thermogravimetry Analysis of Textile Fibers

The principles of thermogravimetry analysis in the test of textile fibers composition and TG curves analysis were introduced.The pyrolysis processs of onecomponent textile fiber were studied with TG analysis at programmed heating-up speed.Then the differences of TG curves about six kinds of textile fibers were compared and based, on the thermogravimetry curves linear superposition theory of mixtures, a thermogravimetry curve model of two-component mixture had gotten.Eventually an actual thermogravimetry curve of polyester-cotton fabrics verified the thermogravimetry curve model,it proved that thermogravimetry can apply on the quantitative analysis of mixed fibers.
