The present invention concerns a sizing composition for glass fibers comprising the following components: (a) A silane based coupling agent which is not an aminosilane; (b) A film former; (c) A borate; (d) A lubricant Characterized in that, at least 75 wt. % of the silane coupling agent present in the composition is dialkoxylated. It also concerns a glass fiber sized with the reaction product of said sizing composition, as well as a polymeric composite reinforced with such glass fibers.

Mineral wool insulation products are provided. The mineral wool insulation includes a plurality of mineral wool fibers and a wax emulsion applied to the mineral wool fibers. The wax emulsion imparts excellent water resistance and thermal performance properties to the mineral wool insulation.

Embodiments generally relate to devices and methods for production of fibers and threads for use in electronic device manufacturing. Described here, fibers can be produced and manipulated using a dual-surfaced sizing material. The dual-surfaced sizing material has a surface which binds a fiber and a surface which binds a resin. Thus, the dual-surfaced sizing material can be left attached to the fibers without adversely affecting the resin binding in later production steps.

The sizing composition includes, based on the total solids mass of the composition, 0.1 to 5.0% by solid mass of a first silane coupling agent, 2.5 to 11.0% by solid mass of a second silane coupling agent, 3.0 to 20.0% by solid mass of a first film former, 45.0 to 75.0% by solid mass of a second film former, 0 to 5.0% by solid mass of a plasticizer, 0.2 to 4.0% by solid mass of a first lubricant, 5.0 to 20.0% by solid mass of a second lubricant, and 0.01 to 3.0% by solid mass of a pH regulator. The first film former is a multifunctional epoxy emulsion, and the second film former is a low-molecular-weight liquid epoxy emulsion.

Known methods of producing a three-dimensional glass object comprise the step of shaping of a glass fiber, wherein the glass fiber provided with a protective sheath is fed continuously to a heating source, the protective sheath is removed under the influence of heat, and the glass fiber is softened. In order to facilitate the production of filigree or optically distortion-free and transparent glass objects as much as possible, and also enable the adjustment of optical and mechanical properties with high spatial resolution, in one aspect the glass fiber has a protective sheath with a layer thickness in the range of 10 nm to 10 μm.

The surface-treated glass cloth includes a surface treatment layer on a surface, and the surface treatment layer includes: a first silane coupling agent containing at least one amine selected from the group consisting of a primary amine, a secondary amine and a tertiary amine and containing no quaternary ammonium cation; a second silane coupling agent containing at least one quaternary ammonium cation; an organic acid; and a surfactant. A total content of the first silane coupling agent and the second silane coupling agent is 0.05 to 1.20 mass% based on the total amount of the surface-treated glass cloth, a ratio of a molar content of the first silane coupling agent to a molar content of the second silane coupling agent is 1.1 to 10.0, and a content of the organic acid is 50 to 300 ppm based on the total amount of the surface-treated glass cloth.
