EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN ISO 1833-13 testing. This standard specifies a method using carbon disulfide/acetone to determine the mass percent of chloro fiber, after removal of the non-fibrous material, in textiles made from carbon disulfide/acetone mixtures.
Certain chlorofibres, along with wool, animal hair, silk, cotton, viscose, cupro, modal, lyocell, polyamide, polyester, elastomultiester, acrylic, melamine, polypropylene, polypropylene/polyamide bicomponent, polyacrylate and glass fibers.
It is also possible to analyze blends containing chlorofibre using the test methods described in EN ISO 1833-17 or EN ISO 1833-21.
The chlorofiber is dissolved from a known dry mass of the mixture with an azeotropic mixture of carbon disulfide and acetone. The residue is collected, washed, dried and weighed; the corrected mass if necessary, expressed as a percentage of the dry mass of the mixture. The percentage of chlorofibre is found by the difference.
In some mixtures with a high chlorofiber content, significant shrinkage of the sample may occur during the drying process, resulting in delayed dissolution of the chlorofiber by the solvent. However, this does not affect the final dissolution of the chlorofiber by the solvent.
