Title:
FIRE-RESISTANT POLYESTER CONJUGATED YARN
Document Type and Number:
Japanese Patent JPS6241317
Kind Code:
A
Abstract:
PURPOSE: To obtain yarn having permanent fire resistance and improved strength characteristics, by adding a specific amount of an inorganic boron compound to a core component of core-sheath type polyester conjugated yarn.
CONSTITUTION: 0.5W5.0mol% based on total acid components of a polyester constituting yarn of an inorganic boron compound is added to a core component of core-sheath type polyester conjugated yarn. Orthoboric acid, boron oxide (diboron trioxide, diboron dioxide, tetraboron trioxide, tetraboron pentoxide, boron monoxide, etc.,), metaboric acid, etc., may be cited as the inorganic boron compound.
