Problems solved by technology

[0002] At present, it has been reported that polyester fibers with dual functions of flame retardant and antistatic have been produced, but bromine or phosphorus flame retardants and organic antistatic agents are generally used for fabric finishing, and the flame retardant and antistatic functions are not firm.
There is also a method of adding flame retardants to produce fibers, but there is no process and method for adding inorganic antistatic agents at the same time, and the antistatic properties of the fibers produced in this way are not obvious.

Embodiment Construction

[0014] best practice

[0015] A kind of manufacture method of flame-retardant-antistatic polyester fiber, raw material PTA (terephthalic acid) and EG (ethylene glycol) carry out esterification reaction under the condition of heating, generate BHET (ethylene terephthalate glycol) After the esterification monomer), the monomer material after esterification is introduced into the polymerization tank, and after the esterification reaction is completed, the esterified product is injected into the polymerization tank with nitrogen pressure. In the normal compression polyreaction stage, first add the inorganic antistatic agent EG (ethylene glycol) slurry prepared in advance in the material, the inorganic antistatic powder addition is 3Wt% (to PET weight ratio), the inorganic antistatic agent is used EG (Ethylene glycol) was prepared into a 20wt% slurry. After 5 minutes, the phosphorus-based flame retardant monomer EG (ethylene glycol) solution was dropped into the material of the po...

Abstract

The invention relates to a making method of flame-proof-and-antistatic polyester fiber, which comprises the following steps: generating BHET terephthalic glycol ester monomer after the esterifying reaction of raw PTA terephthalic acid and EG glycol ester in the heating condition; leading the material into polyaxe; adding the preparing modulated functional additive of inorganic antistat EG glycol ester slurry in the atmospheric polycondensation reaction stage; putting the phosphorus-series flame retardant monomer of EG glycol ester solution into the polyaxe after 5 minutes; starting pressure-relief reaction after 5 minutes; generating the flame-proof-and-antistatic composite functional polyester microtome section by cooling the fondant; textiling the flame-proof-and-antistatic composite functional polyester microtome section into everlasting flame-proof-and-antistatic composite multi-functional polyester staple fiber. The technological program is reasonable and easy to operate.

Description

technical field [0001] The invention relates to a method for manufacturing multifunctional PET (polydimethyl terephthalate) short fibers. In particular, it relates to a method for manufacturing a flame-retardant-antistatic polyester fiber. Background technique [0002] At present, it has been reported that polyester fibers with dual functions of flame retardant and antistatic have been produced, but bromine or phosphorus flame retardants and organic antistatic agents are generally used for fabric finishing, and the flame retardant and antistatic functions are not firm. There is also a method of adding flame retardants to produce fibers, but there is no process and method for adding inorganic antistatic agents to blend at the same time, and the antistatic properties of the fibers produced in this way are not obvious. Contents of the invention [0003] The purpose of the present invention is to synthesize polyester staple fibers with two functions of flame retardant and ant...
