The invention discloses a process for preparing
flame retarding
cellulose viscose, which adopts
pyrophosphate exchange reaction
flame retardant particle whose mean particle
diameter is <= 1.0um, non-ionic surface
active agent, dispersing agent and
solvent water to mix and obtain
flame retardant
emulsion, each percentage by weight is
pyrophosphate exchange reaction flame retardant 20-45 wt%, non-ionic surface
active agent 5-10 wt% and dispersing agent 0.5-1.0 wt%, and residue is
solvent water. The process for preparation comprises adding
pyrophosphate exchange reaction flame retardant of flame retardant
emulsion which is corresponded to
alpha cellulose 15-30 % into
spinning original liquid which is filtered to mix, shaping
spinning by adopting
spinning bath which is low acid,
low salt, low temperature and high
zinc. The spinning original liquid of the invention has simple and convenient preparation,
fiber does not contain
halogen elements, which avoids environmental
pollution, when in burning, the invention is not melted, while
charring only happens to keep the original shape of
fiber, the invention prevents dripping which is melted in high temperature from
scalding human body, and flame retardant is distributed evenly in
adhesive, which can not smolder after leaving fire and easy to be self-extinguished.
