  • Resin compatible yarn binder and uses thereof
    Patent number: 8062746
    Abstract: A fiber strand comprising at least one fiber at least partially coated with a composition formed from at least one rosin, at least one cationic lubricant, at least one film forming material, at least one organosilane coupling agent, and at least one dispersion of polymeric particles. A fiber strand comprising at least one fiber at least partially coated with a composition formed from components comprising at least one rosin, at least one polymeric lubricant, at least one film forming material, at least one organosilane coupling agent, and at least one dispersion of polymeric particles. A fiber strand comprising at least one fiber at least partially coated with a starch-free composition comprising at least one rosin, at least one cationic lubricant, at least one film forming material, and at least one organosilane coupling agent.

  • Resin compatible yarn binder and uses thereof
    Publication number: 20060078721
    Abstract: Certain embodiments of the invention are directed to a fiber strand comprising at least one fiber at least partially coated with a starch-free composition formed from the components comprising at least one film forming material, at least one polymeric lubricant, at least one rosin, at least one organo silane coupling agent, at least one dispersion of polymeric particles, wherein the individual particles have a diameter of at least 0.1 microns, at least one emulsifying agent, and at least one additional lubricant that is different from the at least one polymeric lubricant.

  • Fiber product coated with particles to adjust the friction of the coating and the interfilament bonding
    Publication number: 20050025967
    Abstract: The present invention provides a glass fiber product having particles adhered to at least one fiber of the product, where the size and amount of particles is effective to reduce the tackiness of the glass fiber product and optionally effective to reduce interfilament bonding, and composition, and method for forming the same.
