Method for producing sized glass fibers and resulting products

Номер: US0006322888B1

A process for producing sized glass yarns, which entails:a) drawing streams of molten glass from orifices located at a bottom of one or more dies, in a form of one or more fans of continuous filaments,b) assembling the filaments into one or more moving supports,wherein a first stable composition having a viscosity of between 0.5 and 250 cP is deposited onto the surface of the continuous filaments, and a second stable composition, supplied separately from the first and having a viscosity of between 0.5 and 300 cP, is deposited onto the surface of the filaments of the yarns, at the earliest during deposition of the first composition and at the latest during collection of the years, the difference in viscosity between the two compositions deposited being less than 150 cP, the mixture of the deposited compositions functioning as a sizing composition and being polymerizable at room temperature.

Process for quantifying the moisture in a fiber blanket

Номер: US0011353408B2
Принадлежит: SAINT-GOBAIN ISOVER

A process for quantifying the moisture in a blanket of fibers includes the emission of an incident electromagnetic wave towards the blanket, by at least one emitter; the receiving of the electromagnetic wave transmitted through the blanket, by at least one receiver; the identification of a variation of at least one parameter of the transmitted wave relative to the incident wave; the determination of a representative value of moisture in the blanket of fibers, as a function of the variation and of the effective volume of blanket that has actually interacted with the incident wave.
