[anti-flammability textile material and preparation method thereof]
The method for preparing anti-flammability textile material of the present invention comprises above-mentioned fire retardant is coated to step (finishing (finishing) step) on the textile material.
In the finishing step, fire retardant and textile material are in contact with one another so that the phosphorus compound in the fire retardant (A) is coated on the textile material.The finishing step comprises, for example, wherein textile material contained 2 to 120 minutes step (step 1) of dipping in the bath of fire retardant in the temperature more than 80 ℃; With another method, wherein fire retardant is coated on the textile material, then textile material is heated so that phosphorus compound (A) is penetrated into (step 2) in the textile material at 100 to 220 ℃.
In step 1, phosphorus compound (A) is coated on the textile material by following method usually: textile material is immersed in by in the prepared bath of dilute with water fire retardant, thereby (A) is coated on the textile material with phosphorus compound, and will be immersed in the textile material heating 2 to 120 minutes in the bath of the temperature more than 80 ℃, so that flame-retardant nature is durable.The thinner ratio of fire retardant is not particularly limited, but is generally 10 to 10000 times water.The treatment temperature of textile material in bath should be preferably more than 80 ℃, more preferably 90 ℃ to 150 ℃, because the amorphous regions of textile material is lax or expansion, thereby quickens the coating of phosphorus compound (A) to textile material.Step 1 can operative installations for example jet dyeing machine, beam dyeing machine and yarn package dyeing machine carry out.
In step 2, by textile material being immersed in by in the prepared bath of dilute with water fire retardant and phosphorus compound (A) is coated on the textile material, and the textile material that will behind dipping, be dried sometimes heating, so that phosphorus compound (A) is penetrated in the textile material, thereby make flame-retardant nature durable.Heating-up temperature should be preferably 100 to 220 ℃, more preferably in 160 ℃ to 200 ℃ the scope,, thereby quicken the coating of phosphorus compound (A) to textile material because the amorphous regions of textile material is lax or expand.Preferably be not lower than 100 ℃ heating-up temperature,, thereby give the flame-retardant nature of poor durability sometimes because so low temperature can't obtain the abundant infiltration of phosphorus compound (A) in textile material.On the other hand, preferably be not higher than 220 ℃ heating-up temperature, because excessive heat possibility deterioration textile material, thereby the toughness of reduction textile material.Can use dip-dye, spray or be coated with fire retardant is coated on the textile material.Heating can be by xeothermic or damp and hot carrying out.This coating and heating means comprise sprays and dried cure system, dip-dye and net gas steaming system, dip-dye and decatize system and dip-dye and dried cure system.
The preparation method of anti-flammability textile material of the present invention can comprise at least one in above-mentioned steps 1 and the step 2.Repeat identical step or can give textile material better flame-retardant nature step 1 and step 2 combination.In addition, the preparation method of anti-flammability textile material of the present invention can also comprise the finishing step that another uses the fire retardant different with fire retardant of the present invention.
In the preparation method of anti-flammability textile material of the present invention, fiber finishing agent and the fiber finishing auxiliary agent that is different from fire retardant of the present invention can be used for textile material is carried out finishing.Other fiber finishing agent and fiber finishing auxiliary agent comprise, for example, the fire retardant, dyestuff (basic-dyeable fibre and DISPERSE DYES), carrier (aromatic halide class, N-alkyl phthalimide, aromatic carbonate, methyl naphthalene, biphenyl, biphenyl ester, naphthol ester, phenol ether, xenol etc.), deodorant, antiseptic, softening agent, antistatic additive, waterproofing agent, oil-proofing agent, curing agent, ultra-violet absorber, anti-fouling agent and the hydrophilizing agent that are different from phosphorus compound (A).Can use a kind of in the described reagent or at least two kinds.
In the preparation method of anti-flammability textile material of the present invention, fire retardant on the textile material, the amount (amount of obtaining (pickup)) that is phosphorus compound (A) is not particularly limited, because it changes according to following condition, such as, the variant of textile material and structure and the variant and the amount of obtaining that are coated on other fiber finishing agent on the textile material.Preferably the amount of obtaining should be at 0.1 to 30 weight % of textile material, more preferably in the scope of 1 to 20 weight %.The amount of obtaining less than the phosphorus compound (A) of 1 weight % possibly can't give textile material sufficient flame-retardant nature.On the other hand, greater than the amount of obtaining of 30 weight % may the resulting anti-flammability textile material of deterioration feel, also may be uneconomic the fire retardant of the amount of obtaining just no longer further improves flame retardant effect because surpass necessarily.
