    摘要: A process is described for the preparation of water repellent materials made of acrylic fibre which comprises:

    (a) a first step in which the material is subjected to Plasma treatment in the presence of a reactive gas or a mixture thereof with a noble gas; and
    (b) a second step in which the material obtained in step (a) is subjected to waterproofing by means of (i) traditional resin finish or (ii) with Plasma generated in the presence of fluorinated compounds.

    The materials made of acrylic fibre thus obtained are characterized by a waterproofing degree higher than 25 cm of water column and have a rigid appearance or good draping and softness depending on whether they have been waterproofed with treatment (i) or (ii).
    These materials are used in the preparation of covers or sun shields.

    摘要: A process is described for flame-proofing organic polymeric materials by means of a low temperature plasma treatment in the presence of at least one volatile, low-molecular compound. The process comprises subjecting a volatile compound, selected from a halogen-free phosphorus compound, to the low temperature plasma, such that a homogeneous polymeric structure forms on the organic material. A very wide range of organic materials can be effectively flame-proofed with the process of this invention without adversely affecting their other properties such as mechanical properties or photochemical stability.

    摘要: Le filtre comprend un substrat filtrant comportant des fibres organiques, naturelles ou synthétiques, dont au moins une partie sont greffées avec au moins un monomère organique capable de retenir physiquement et chimiquement certaines des particules à éliminer véhiculées par le flux gazeux. Les fibres sont avantageusement greffées par irradiation à la température ambiante puis tissées ou aiguilletées, les fibres comprenant avantageusement des fibres multigreffées ou un jeu de fibres différemment greffées. Un greffage avec des monomères fluorés améliore en outre les qualités de filtrage mécanique du filtre.
