  • FLUORESCENT FIBER, ITS USE AND PROCESSES FOR ITS PRODUCTION
    Publication number: 20160138217
    Abstract: The present invention relates to a regenerated cellulosic fiber which contains an incorporated dye pigment and a fluorescent dye applied by overdying, the use of this fiber for the production of yarns and fabrics and a process for the production of these fibers. This fiber satisfies the demands of EN 471 in relation to luminance factor, the chromaticity coordinates and color fastness and possesses a light fastness (ISO 105-B02, process 2) of more than 5.

  • COLORED FLAME RETARDANT SHAPED CELLULOSIC ARTICLE AND PRODUCTS PRODUCED FROM IT
    Publication number: 20130149932
    Abstract: The objective of this invention is to enable the production of colored shaped flame retardant cellulosic articles such as fibers and to use them to produce fabrics and similar items simply and at lower cost than if they were colored by dyeing after production. A product has been invented that is a fiber which is colored using an included pigment during its manufacture.

  • FLAME RETARDANT FABRIC FOR PROTECTIVE CLOTHING
    Publication number: 20120270456
    Abstract: The product of the invention is a flame retardant fabric for use in personal protective clothing which provides a high level of protection from flames or other sources of heat characterized in that it is made from a mixture of a primary yarn which is a blend of FR cellulosic fibers with high temperature resistant polymer fibers and a secondary yarn which is a twisted yarn containing a continuous synthetic filament yarn.
