Abstract

Studies have been made on the structure of wool fibres treated with trichloroethylene (TRI) and tetrachloroethylene (PER) by means of differential thermal analysis (DTA), differential scanning calorimetry (DSC) and X-ray diffractometry.

The samples were treated with TRI at temperatures ranging from 40‡ to 87‡, and with PER at temperatures from 40‡ to 121‡. TRI and PER treatment caused changes in the wool samples which were detected on the DTA curves. Changes in the degree of order brought about by TRI and PER, calculated from the DSC scans, were in accord with those determined from the X-ray data. The wool samples treated with TRI showed an increase, and those treated with PER a decrease, in the content of the ordered phase as the treatment time was increased.

Zusammenfassung

Die Struktur von mit Trichloräthylen (TRI) und Tetrachloräthylen (PER) behandelten Wollfasern wurde differentialthermoanalytisch (DTA), differentialscanningkalorimetrisch (DSC) und röntgendiffraktometrisch untersucht. DieProben wurden mit TRI im Temperaturbereich von 40–87‡ und mit PER bei Temperaturen von 40–121‡ behandelt. Die Behandlung mit TRI und PER führte zu Veränderungen der Wollproben, die sich in den DTA-Kurvenzu erkennen geben. TRI- und PER-Behandlung haben Veränderungen des aus Röntgendaten berechneten Ordungsgrades zur Folge. Die mit TRI behandelten Wollproben zeigten eine Vergrösserung, die mit PER behandelten dagegen eine Verminderung des Gehalts an geordneter Phase mit steigender Behandlungszeit.
