In-situ polymerized multi-functional composite polyester fiber

Functional update and technological deconstruction. Fiber technology has stepped up the stairs of the times in the development and iteration, coexists with ecology, functions and emotion, and continuously extends more potential. With our increasing demands for health management, the functional protection of the body has obtained more attention. Cool feeling,bacteriostasis, far infrared, heat locking and cooling, anti-ultraviolet, anti-static electricity and air purification have become our great demands for psychological security.Multi-functional composite fiber provides the best care in healthcare, safety protection and heat-humidity adaptation, helping us travel freely with no fear of environmental changes and experience the fashion of life technology.

FUNCTIONAL DECONSTRUCTION

MULTIFUNCTIONAL COMPOSITE FIBER

Multi-functional composite fiber, guarding health with leading technology.Miraculous rare earth functional particles create lightweight, heat insulation and cooling,infrared reflection functions, creating thermal comfort for the human body with surrounding micro-environment.In-situ polymerization modification technology deeply embeds anti-bacteria, flame retardant, anti-static, anti-ultraviolet, formaldehyde-removal and other multiple functions into molecular chain segments, making one fiber with multi-purpose. It pioneers in dual anti-bacteria effect of plant and animal active substances, and upgrades the contents of cellulose fiber protein and 14 kinds of amino acids,escorting scientific health care.

In-situ polymerized multi-functional composite polyester fiber

Recommendation Reasons

Through in-situ polymerization multi-functional composite technology, the compatibility problem between inorganic materials and polymers is solved. Therefore, the fiber possesses the properties of polyester, and multiple functions such as anti-bacteria,flame-retardant,anti-static,anti-ultraviolet

and formaldehyde-removal, etc., and can be applied in various scenarios

such as medical treatment and public health, sports & outdoor, businesstravel, and overalls protection.

Processing Technology

The in-situ polymerization modification method is used. lnorganic nano-mineral bacteriostat

and flame retardant are added after polyester esterification, and then multi-functional integrated

polyester slices are produced by polycondensation. Finally, melt spinning is performed to produce the multi-functional composite fiber.

Q: Do you know the mechanism of phosphorus flame retardant?

A:The mechanism of phosphorus flame retardant has three aspects:

(1) Gaseous-phase flame retardant. Phosphorus-containing compounds are

decomposed into micro-molecular free radicals such as ●POz,●PO and ●HPO etc. And such free radicals react with H and OH free radicals generated during the combustion process to realize flame retardant by interrupting the combustion reaction chain;

(2) Condensed-phase flame retardant. Phosphorus-containing compounds

generate phosphoric acid with a boiling point of 300°℃ during the

combustion process, and the phosphoric acid is further dehydrated to

generate metaphosphoric acid and poly-metaphosphoric acid to promote

the dehydration and carbonization of PET polymer chain, and form dense

charcoal layer on the combustion surface to insulate air and hinder heat

transfer, thus realizes flame retardant;

(3) During the combustion process, phosphorus-containing compounds can

generate water, diluting combustible gases and taking away combustionheat, thus enhances the flame retardant effect.
