Title:
FIRE RETARDANT ANTIFLUX FIBER AND ITS PRODUCTION PROCESS
Document Type and Number:
WIPO Patent Application WO/2008/080270
Kind Code:
A1
Abstract:
The present invention provides a fire retardant antiflux fiber, the fiber is composed of the following components: cellulose 60%-80% by mass, silicon fire retardant (caculated as silicon dioxide) 15%-36% by mass, tourmaline 0.1%-5% by mass. The present invention also provides a process of producing fire retardant antiflux fiber, in the adding step, the silicon fire retardant is added into the cellulose sulfonate in the sulfidizing step or the viscose which was prepared after the sulfidizing step, the level of addition of the silicon fire retardant is 19-60% , caculated as silicon dioxide. The fire retardant antiflux fiber of the present invention has high fire retardant antiflux effect, high fiber strength and excellent negative ion generating efficacy. At the same time, the viscose also maintains excellent filtering performance in the procedure using above production process, reducing the production standstill caused by the viscose blocking up filter screen, improving production efficiency. The viscose fiber can be used to fabricate nonwoven fabric widely.
