  • Manufacture of a veil made of glass and cellulose fibers in cationic medium
    Patent number: 8273214
    Abstract: A process for producing a veil comprising glass fibers and cellulose fibers which includes dispersing cellulose fibers and chopped glass fibers into a white water, forming a bed in a forming device by passage of the dispersion over a forming fabric through which the white water is drained off, the fibers being retained on the fabric and the dispersion including, during passage, a cationic white water, and performing a heat treatment step an oven device.

  • Method for making a fiber glass and cellulose mat in cationic medium
    Publication number: 20060113050
    Abstract: The invention relates to a process for producing a veil comprising glass fibers and cellulose fibers which comprises: a step of dispersing cellulose fibers and chopped glass fibers into a white water; then a step of forming a bed in a forming device by passage of the dispersion over a forming fabric through which the white water is drained off, the fibers being retained on said fabric and said dispersion comprising, during said passage, a cationic white water; and then a heat treatment step in an oven device. This process makes it possible in particular to produce a veil comprising 2 to 12 % cellulose, 70 to 80% glass; and 8 to 27 % binder the tear strength of which is greater than 430 gf.
