  • Polypropylene fibers, methods for producing the same and uses thereof for the production of fiber cement products
    Patent number: 10611683
    Abstract: The present invention relates to improved polypropylene fibers and methods for producing the same as well as uses of such polypropylene fibers for the production of fiber cement products. The present invention further relates to fiber cement products, such as flat or corrugated fiber cement sheets, comprising the polypropylene fibers of the present invention. The fiber cement products of the present invention have an improved impact resistance as compared to fiber cement products not containing the polypropylene fibers of the present invention.

  • PROCESS FOR THE TREATMENT OF CELLULOSE FIBERS
    Publication number: 20160053431
    Abstract: A method for the treatment of cellulose fibers is provided, the method comprising the steps of (i) impregnation of cellulose fibers with a solution comprising a tetraalkoxysilane and a solvent selected from monofunctional alcohols R4OH; and (ii) squeezing out the solution from in between the cellulose fiber walls; wherein the weight ratio of the solution to the dry weight of the cellulose fibers after the step of squeezing is lower than 2.

  • Fibre reinforced shaped solid articles
    Patent number: 5338357
    Abstract: The invention relates to shaped solid articles manufactured with a hydraulically setting composition comprising water, hydraulic binders and reinforcing fibres and moreover process fibres in an amount of 0-10 wt % with respect to total dry mix and fillers in an amount of 0-50 wt % with respect to total dry mix wherein the reinforcing fibres comprise from 0.1 to 5 wt % with respect to total dry mix of highly crystalline polypropylene fibres possessing a fibre breakage strength of over 490 N/mm.sup.2, having Q<5 and 97<HI<100, and 94<IPF<100, Q being the ratio of weight-average molecular weight to number-average molecular weight, HI being the boiling n-heptane insoluble content in wt % with respect to the total polymer and IPF being the isotactic pentad fraction in mol %.
