According to GlobalData’s company profile on Nitto Boseki, Interlaced yarn fabrics was a key innovation area identified from patents. Nitto Boseki's grant share as of March 2024 was 46%. Grant share is based on the ratio of number of grants to total number of patents.
The granted patent (Publication Number: US11959203B2) discloses a glass roving cloth designed with specific parameters for warp and weft yarns. The warp yarns consist of glass rovings with filament diameters ranging from 9.5 to 30.0 µm, bundled in a specific range, while the weft yarns have similar characteristics. The weaving density, yarn width, widening rate, and glass occupancy in both directions are meticulously defined within certain ranges to achieve desired properties in the cloth.
Furthermore, the patent claims specify additional features such as the glass occupancy in warp and weft directions, loss on ignition percentage, and widening rates for both types of yarns. The invention extends to a glass fiber-reinforced resin sheet utilizing the glass roving cloth, with a specific proportion by mass of the cloth in the resin sheet. These innovations aim to enhance the mechanical and structural properties of the glass roving cloth and the resulting resin sheet, catering to applications requiring high strength and durability.
