The developing direction of product, every field all constantly propose the demand to different types of flame-retardant textile kind.Flame-retardant textile refers to just
After contact flame or red-hot object, the labor protection fabric that is ignited or can slow down and terminate burning in itself can be prevented.
Currently, general fire-retardant chemical fibre, such as terylene, viscose glue, acrylic, because of the factors such as strength and flame retardant property, Zhi Nengyong
Furnishing items in public places such as some hotels, automobiles, and cannot be used for aerospace, fire-entry suit, anti-flaming gloves, military project
There is certain specific requirement in the fields such as demand, these fields to flame retardant property, the comfort level etc. of fabric.
Invention content
A kind of flame-retarding blended yarn of polyimides of present invention offer and its preparation process, by fire-retardant polyimide fiber
Flame retardant viscose fiber and fire-retardant polyamide fibre is added, obtains the flame-retarding blended yarn of polyimides, comfort level, wearability, chemical stability carry
Height, flame retardant property is more preferably.
To achieve the above object, the present invention uses following technical scheme：
A kind of flame-retarding blended yarn of polyimides, comprises the following raw materials by weight percent：40% fire-retardant polyimides
Fiber, 40% flame retardant viscose fiber, 20% fire-retardant polyamide fibre.Wherein, polyimides has good flame retardant property and fire-retardant
The not characteristic of molten drop and higher strength, flame retardant viscose fiber has characteristic comfortable and easy to wear, sweat-absorbing breathable is good, fire-retardant
Polyamide fibre has very high strength, and 40/40/20 blending ratio has not only taken into account flame retardant effect, but also has taken into account good wears performance,
Strength index is also taken into account, this ratio is best blending ratio fire-retardant, comfortable, strength is high.
The performance standard of the fire-retardant polyimide fiber：It is closeer than strong 5.83CN/dtex, elongation at break 20.28%, line
Spend 1.5D, length 38mm, regain 2.0%；The performance standard of the flame retardant viscose fiber:It is stretched than strong 1.8CN/dtex, fracture
Long rate 17.20%, line density 1.5D, length 38mm, regain 10.24%；The performance standard of the fire-retardant polyamide fibre:Than strong
3.61CN/dtex, elongation at break 76.70%, line density 1.5D, length 38mm, regain 1.7%.
The present invention also provides a kind of preparation processes of the flame-retarding blended yarn of polyimides, include the following steps：
(1) raw material prepare：Fire-retardant polyimide fiber, flame retardant viscose fiber, fire-retardant polyamide fibre are selected, and in proportion uniformly
Mixing；
(2) cotton cleaning process：Above-mentioned uniformly mixed raw material are attached to mixed cotton slitter, comb needle type opener, to cotton successively
Machine, vibratory cotton feeding machine through lapper in rolls, beat less using more pines, and the technique for increasing tight layer roller pressure carries out fully
Mixing；
(3) carding step：Obtained fiber cotton roll is combed into item, is used for drafting；
(4) mixing in doubling step：Using drawing process three times；
(5) spinning process：Rove use big gauge, four roller drafts, Distribution Area drafting multiple control at 1.08 times, after lead
Multiple control is stretched at 1.3 times, and dominant draft multiple controls and is spun into the rove that twist factor is 80 at 7.76 times, and spun yarn uses big
Back area draft gauge and small back zone drafting multiple, drafting multiple are controlled at 1.08 times, it is ensured that resultant yarn strand quality；
(6) post-processing process：Using being spun into the yarn for meeting technique from bobbin-winding machine winder.
The present invention advantageous effects be：
By the way that flame retardant viscose fiber is added in polyimides, gas permeability, the anti-flammability of fabric improve, and chemical property is steady
Fixed, wearing comfort also improves, and by the way that fire-retardant polyamide fibre is added, reduces frictional static in spinning and weaving process and fiber is swollen
The phenomenon of pine makes each process production that can be smoothed out, reduces the generation of yarn defect, improve bar evenness, improve resultant yarn
Strongly, wearability is increased；The scribbled that the present invention produces, item is dry uniformly, strength is high, filoplume is few, yarn defect is few, has good
Good radiation resistance, acidproof, alkaline resistance properties, do not soften, do not melt at high temperature, have a good mechanical performance, elongation compared with
Stablize, fits entirely into space flight, military, civilian fire protection flame retarding requirement.
Specific implementation mode
The present invention is further explained in the light of specific embodiments.
Embodiment 1
