Description
Technical field
The present invention relates to a kind of processing method and safe air bag fabric of safe air bag fabric.
Background technology
As the air bag of one of automotive safety spare part, along with the raising of people's awareness of safety, installation rate improves rapidly.The groundwork process of air bag is: after colliding, open a gassiness sack rapidly between occupant and Che inner part; occupant is allowed to flutter on air bag; the kinetic energy of passenger is absorbed by the discharge throttle of air bag; collision in fierce car is cushioned, to reach the object of protection passenger.
At present, weaving of textile for air sacs mainly adopts water jet looms, air-jet loom and Rapier looms.Comparatively large by the hardness of the woven textile for air sacs of water jet looms, and the diagonal degree of cloth cover is comparatively large, affects fabric cutting utilization rate.Rapier looms rotating speed is lower, and cost is relatively high.
In Chinese patent Authorization Notice No. CN102212960B, describe a kind of fabric for airbag warp-weft directional elongation deviation minimization process, this technique comprises washing refining, extruding drainage, heat arrangement and cooling.This patent does not relate to the physical property of fabric, does not more describe the air-jet loom that warping adopts Sizing Technology, wet end furnish and weaves employing.
Non-coat automotive safe air bag fabric and preparation technology thereof is described at Chinese patent application publication No. CN101984165A.But this patent does not relate to the kind of slurry, the proportioning of destarch solution, the extraction value of fabric.
Summary of the invention
The present invention adopts air-jet loom, reasonable disposition starching, desizing, obtains the extraction foreign substances < 0.4% of fabric, and the dynamic venting quality of fabric can be 300 ~ 700mm/s.
The present invention adopts air-jet loom weaving, after starching destarch, and foreign substances content≤0.4% in fabric; The dynamic air permeability of fabric remains on 500-700mm/s.If do not adopted starching, so yarn easily produces filoplume in air-jet loom weaving process, and weaving efficiency declines.After starching, if do not adopted desizing, fabric hardens on the one hand, is unfavorable for the development trend that air bag fabric folding property is good; On the other hand, the foreign substances > 0.4% of fabric, can not meet air bag foreign substances index.If the dynamic air permeability > 700mm/s of fabric, then softer during airbag deployment, do not have the available protecting to human body.As the dynamic air permeability < 500mm/s of fabric, then when airbag deployment because fabric permeability is little, gunpowder explosion produce energy can not distribute in time, easily cause airbag to make position and tear, rupture.
According to an aspect of the present invention, the invention provides a kind of processing method of safe air bag fabric, described safe air bag fabric processing method comprises: warping starching, uses air-jet loom weaving safe air bag fabric, and to the safe air bag fabric destarch of weaving; It is characterized in that: the slurry in the aqueous slurry solution adopted in described warping slashing step is water-soluble polypropylene acid fat slurry, and the structure of described water-soluble polyacrylate slurry is:
，
Wherein R is-(CH
2) nCH
3.
Described water-soluble acrylic ester slurry mainly with
Acrylic acid
,
Methacrylic acid
,
Itaconic acid (methylene-succinic acid)
,
Butyl acrylate
In the mixture carrying out being obtained by reacting for monomer, in wherein said water-soluble polyacrylate slurry, polyacrylic concentration is 50-80%.
The concentration of described aqueous slurry solution is 6-8%.
Preferably, the pH value of described aqueous slurry solution is 2.2-2.3, boiling point > 100 DEG C, density 1.14g/m
3.
The vitrification point of new type water-solubility polyacrylate of the present invention is 22 DEG C ~ 30 DEG C.Owing to containing hydrophilic units structure in slurry, slurry ratio is easier to and water combines, and is easier to destarch.The vitrification point < of slurry 22 DEG C, soft in weaving process, sticky phenomenon easily occurs; As vitrification point > 30 DEG C, then after starching, serous coat is too hard, easily comes off from yam surface, pollute in weaving process.
Safe air bag fabric of the present invention and processing technology thereof, desizing adopts NaOH solution, refining agent, dispersant, bleeding agent and water.Desizing can adopt 5 grooves, before 2 be pharmacy slot; 3 next is rinsing bowl.2 pharmacy slot Chinese medicines adopt NaOH solution, refining agent, dispersant, bleeding agent and water, and the important chemical composition of NaOH solution is 48% caustic soda.Refining agent is surfactant, organic solvent and water mainly.Dispersant main component is the anion based polymer that the art is commonly used.Bleeding agent main component can be methyl alcohol and ethylene glycol monobutyl ether.
In a concrete embodiment, containing methyl alcohol about 4.5%, ethylene glycol monobutyl ether about 4% in described bleeding agent.
In a concrete embodiment, the proportioning of NaOH solution, refining agent, dispersant, bleeding agent and water is 48L:2.4L:3.6L:3.6L:3000L.
In safe air bag fabric processing method of the present invention, terylene or the polyamide fibre yarn of the yarn of starching to be line density be 300 ~ 600dtex.
According to a further aspect in the invention, the invention provides a kind of safe air bag fabric obtained according to said method, the warp of this safe air bag fabric, broadwise tensile break strength > 2800N/5cm.Like this, safe air bag fabric of the present invention can play the protective effect to human body effectively.
Further, described safe air bag fabric grabs intensity through broadwise pin is 400 ~ 1000N.
Further, described safe air bag fabric warp, filling-tear resistance are 120 ~ 300N.Preferably, warp, the preferred > 15ON of filling-tear resistance of described safe air bag fabric.Most preferably, warp, the filling-tear resistance 2OON ~ 300N of described safe air bag fabric.
The warp of fabric, filling-tear resistance > 300N, then high to the long filament performance requirement weaving use, the rising of production cost can be caused.As the tearing strength < 120N of fabric, then the concentrated stress effect that when fabric can not bear airbag deployment, high pressure-temperature air-flow produces the impact of air bag, can not play the protective effect to human body.
