Abstract
The present invention relates to flameproof textile articles and to processes for obtaining the same. The textile articles consist or consist essentially of halogen-containing modacrylic polymers containing on their surface about 0.2% to 2% by weight of silica relative to the weight of the articles. They are obtained by treatment with an emulsion of a hydrogenopolysiloxane compound in the presence of a curing catalyst, followed by a heat treatment at a temperature which can vary between about 100.degree. and 160.degree. C. They are of great value in certain flameproof textile applications such as household furnishings and garments.
Claims2
A flameproof textile article consisting essentially of a halogen-containing modacrylic polymer treated with a hydrogenopolysiloxane compound such that the proportion of hydrogenopolysiloxane, expressed in terms of SiO.sub.2 contained therein, is between about 0.2% and 2% by weight of the treated article.
