PROCESS OF TISSUE PROCESSING FOR FOAMED PIECES IN MOLD AND USE OF SUCH TISSUE (MACHINE-TRANSLATION BY GOOGLE TRANSLATE, NOT LEGALLY BINDING)
ES2394689
Process of treatment of fabrics for foamed pieces in mold and use of said fabric. The invention relates to a method of treating tissues by: i) treating the unseen face of the tissue with a hydrophobicizing agent to form a hydrophobic film on said tissue surface; ii) drying said hydrophobic film; iii) application of a first waterproofing agent to form a first impermeable film on said hydrophobic film; iv) drying said first impermeable film; v) application of a second waterproofing agent to form a second impermeable film on said first impermeable film; and vi) drying said second impermeable film. The invention also relates to the use of the fabric obtained to manufacture upholstered furniture or resting elements. (Machine-translation by Google Translate, not legally binding)
To date, there is no treatment of conventional textile materials or fabrics for their use in direct foaming in moulds applying vacuum to obtain upholstered parts, mainly due to problems related to the difficulty of these fabrics to adapt to the shape of the mould and the difficulty to prevent the foam mixture from passing through the fabric and impregnating the exposed face of the mould. The present invention aims to solve the problems of the prior art by providing a process for treating fabrics or textile materials in order to obtain a fabric suitable for foam parts by direct casting in moulds equipped with vacuum systems to adapt the fabric to the shape and geometry of the mould.
