International Classification:

B65H 5502

US Classification:

206410

Abstract:

A package of wound glass fiber strand from which the glass fiber strands can be removed more efficiently for feeding into processing operations. The wound package of glass fiber strand is a package of superimposed annular layers of glass fiber strands having a central longitudinal, cylindrical cavity about which the strands are wound and having an outer cylindrical surface and a substantially flat circular top and bottom section. This package is covered with a stretchable polymeric film having a stiffness modulus of at least 1200 pounds/square inch and an elongation of about at least 5 and a thickness of about 0. 75 to about 10 mils. The stretchable polymeric film is stretched around the package of glass fiber strands with a force greater than 4 pounds (18 Newtons) to stretch the film to cover the outer peripheral, cylindrical portion and to extend at least 0. 5 inches (1. 27 cm. ) radially onto the top and bottom flat circular portions of the package.

International Classification:

C03C 2502

US Classification:

65 343

Abstract:

A sizing composition and process are provided for producing wound packages and particularly precision wound packages of glass fiber strand and/or roving. The sizing composition has a total solids content in the range of about 9 to about 30 weight percent and comprises a phenolic epoxy resin, the reaction product of a partial ester of a polycarboxylic acid containing one or more unesterified carboxyl groups with a compound containing more than one epoxy group; and organo silane or silanes; a non-ionic surface active agent; a protective colloid; and a cationic lubricant. The process for producing the precision wound packages of glass fibers includes forming a plurality of glass fibers from molten glass, treating the glass fibers with the sizing composition having a total solids content of about 9 to about 30 weight percent, gathering the treated glass fibers together into one or more strands and collecting the gathered strand or strands on a winder in a precision wound package to produce glass fiber strands or roving.

International Classification:

C04B 3580
D04H 158

US Classification:

428288

Abstract:

Treated glass fibers having adequate protection for gathering into strands and when chopped being more dispersible in aqueous media. The treated glass fibers have a coating of an aqueous treating composition, wherein the solids have a cationic surfactant having one or more primary, secondary and/or tertiary amine moieties and one or more water dispersible, poly(oxyethylene-oxyalkylene) copolymer having an oxide ratio of about 78 to about 22 to about 99 to about 1 and an average molecular weight of at least 15,000, and one or more polar functional coupling agents. Optionally, the solids may also have one or more starches that are insoluble or only incompletely soluble in cold water. Glass fibers treated with the aqueous treating compositions and produced into wet or dry chopped glass fiber strands having lengths of about 1/16 of an inch (1. 58 mm) to about 3 inches (76.

US Classification:

428378

Abstract:

An improved textile forming size for glass fibers utilized in the preparation of rubber coated glass fiber tire cord is described in which a starch based forming size has incorporated therein a non-inoic wetting agent, a silane coupling agent and a paraffinic or microcrystalline wax. The use of this forming size on glass fibers which are subsequently coated with elastomer for use as tire cord results in a tire cord having improved flex fatigue properties.

International Classification:

B32B 900
D02G 300

US Classification:

428391

Abstract:

Chemically treated glass fibers of the present invention perform well as wet chopped strands of glass fibers and are useful in producing glass fiber paper. In one aspect the chopped strands of glass fibers have an aqueous chemical treatment comprised of at least one water soluble, ungelled polymer having an effective viscosity, an effective film-forming capability and an effective molecular weight. In another aspect the chemically treated glass fibers have a chemical treating composition having a polyoxyethylene polymer as the water soluble and ungelled polymer with an effective film forming molecular weight along with water soluble, dispersible or emulsifiable aldehyde-condensate-reactable, polymeric agent, cationic lubricant or lubricating surfactant, aldehyde-condensate-reactable organo silane coupling agents and a carrier like water. The amount of the reactable polymeric agent is an effective white water compatible amount, where this agent is a polymer like either polyacrylamide or polyamide or a mixture of these. The aldehyde-condensate-reactable organo silane coupling agent can be an alkoxylated gamma aminoalkyltrialkoxy silane, a polyamino organo silane, mercapto functional organo silane or a ureido functional organo silane or a mixture thereof.
