    Abstract: A process for the preparation of water repellent acrylic fiber materials which includes (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 fiber obtained by the process have 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 water-proofed with treatment (i) or (ii). These materials may used in the preparation of covers or sun shields.

    Abstract translation: 一种制备防水丙烯酸纤维材料的方法,其包括:(a)第一步骤,其中在惰性气体的反应气体或其混合物的存在下进行等离子体处理; 和(b)第二步骤,其中步骤(a)中获得的材料通过(i)传统树脂涂饰或(ii)在氟化合物存在下产生的等离子体进行防水处理。 通过该方法得到的由丙烯酸纤维制成的材料具有高于25cm的水柱的防水性,并且具有刚性外观或良好的悬垂性和柔软性,这取决于它们是否经过处理(i)或(ii)防水。 这些材料可用于制备盖子或遮阳板。
