Abstract
The present invention belongs to the technical field of flame resisting fiber, particularly to a method for producing flame resisting dacron long threads. A product is obtained by drying and melting polyester chips, extruding out a melting body and spinning the melting body. The present invention is characterized in that the extrusion and the spinning operation are carried out after adding a flame resisting melting body into a polyester melting body, and together mixing the flame resisting melting body and the polyester melting body. The flame resisting melting body is made by drying and melting flame resisting mother particles of which the structural formula is disclosed in the specification. The method uses a novel flame resisting agent, and uses scientific and reasonable preparing technology. Thus, the produced flame resisting dacron long threads have the advantages of softness, elasticity, good flame resistance, long flame resisting period and permanent flame resistance.
Description
The invention belongs to the fire resistance fibre technical field.
Being of wide application of fiber, the fire resistance of fiber has caused people's attention, some countries have also formulated laws and regulations to the fire-retardant requirement of textiles for general use, require curtain, curtain account, old man and the child's of public places such as theater, hospital, hotel clothes all must reach certain flame-retardant standard with textiles, therefore, the fire-retardant of fiber is very important.
At present, brominated organic compound and the antimony oxide of the fire-retardant common employing of macromolecular material is re-dubbed flame-retardant system, this based flame retardant systems, heat endurance is relatively poor, easily in process, decompose, produce corrosive gas, human body is had asphyxiating, and corrosion spinning and other processing of high molecular material equipment.In addition, antimony oxide itself belongs to the non-material that melts, and easily the plate hole of silk or spray silk is squeezed in obstruction in spinning process, changes the shortening of plate cycle thereby make, and reduces production efficiency.Aborning, this based flame retardant at first is mixed in the polyester slice, and by common spinning technique producd fibers, production process is affected, and has also influenced the performance of spinning fibre again.
The object of the present invention is to provide a kind of manufacture method of fire-retardant polyester filament yarn, this method is used BACN, adopts scientific and reasonable preparation technology, makes the fire-retardant polyester filament yarn of manufacturing have superperformance.
Purpose of the present invention can be realized by following scheme:
The manufacture method of described fire-retardant polyester filament yarn, with fusion after the polyester slice drying, with molten mass extrude, spinning obtains product, it is characterized in that in the polyester molten mass, adding fire-retardantly extrude again after melt blended, spinning, fire-retardant melt by structural formula is
The fire-retardant master granule drying after fusion and making.
Above-mentioned fire-retardant master granule is called the SF-FR fire-retardant master granule, produce by Tengzhou City, Shandong textile auxiliary factory, it itself is macromolecule that this fire-retardant master granule has, addition is few, one-component is fire-retardant, do not need synergist, good flame retardation effect, the decomposition temperature height, Heat stability is good, the amount of being fuming is few, nontoxic, non-corrosiveness, good with the macromolecular material compatibility, substantially do not influence characteristics such as the original performance of material, because the chemical constitution of SF-FR fire-retardant master granule is similar to the chemical constitution of polyester and polyamide substantially, make flame-retardant composition and compatibility and spinning rheological characteristic are preferably arranged between the fire-retardant thing, simultaneously also guarantee to be blended into fine back flame-retardant composition and can from fiber, not dissociate out, reached permanent fire-retardant purpose.
Take into account the characteristic of polyester slice and SF-FR fire-retardant master granule, need determine new preparation technology, adjust process, determine reasonable technological parameter.
In the manufacture method of the present invention, used polyester slice is the PET polyester slice, and main component is an ethylene glycol terephthalate.
In the manufacture method of the present invention, the percentage by weight that the addition of fire-retardant melt is controlled at polyester slice and fire-retardant master granule is: polyester slice 90～94% fire-retardant master granules 10～6%, to guarantee spinning quality and to have suitable melt viscosity to be convenient to spinning, can guarantee fire resistance again.
In the manufacture method of the present invention, the baking temperature of fire-retardant master granule is 130～150 ℃, and be 4～6 hours drying time, and effect is better.
In the manufacture method of the present invention, the best melt temperature of fire-retardant master granule is 265～286 ℃.
Manufacture method of the present invention is the improvement of carrying out on original fibre manufacture, has the following advantages:
(1) flame retardant performance is good, addition is few, one-component is fire-retardant, do not need that synergist, good flame retardation effect, decomposition temperature height, Heat stability is good, the amount of being fuming are few, nontoxic, non-corrosiveness, no asphyxia, good with the macromolecular material compatibility, do not influence the original performance and the production requirement of material substantially.
(2) determine production technology according to material performance, scientific and reasonable, implement easily, be convenient to grasp.
(3) the fire-retardant polyester filament yarn performance of this method manufacturing is good, and all indexs all meet standard-required, the fiber softening high resilience, and fire resistance is good, and the fire-retardant effect phase is long, can reach permanent fire-retardant.
The invention will be further described below in conjunction with drawings and Examples.
