Abstract
The invention relates to a manufacturing method of supplementary restraint system fabric. The manufacturing method of the supplementary restraint system fabric comprises warping and starching; weaving the supplementary restraint system fabric through an air jet loom; desizing the woven supplementary restraint system fabric. The manufacturing method of the supplementary restraint system fabric is characterized in that sizing agent in a sizing agent water solution in the sizing and starching step is water solubility polyacrylate sizing agent. The invention also provides the supplementary restraint system fabric machined by the manufacturing method. The supplementary restraint system fabric which is woven by the air jet loom after the reasonable sizing and desizing processes has the advantages of enabling the exotic matter content to be smaller than or equal to 0.4 % and the dynamic air permeability to be remained between 500 to 700 millimeter per second and having other good physical performances.
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 bumping, open rapidly between occupant and Che inner part a gassiness sack; allow occupant flutter on air bag; by the discharge throttle of air bag, absorb passenger's kinetic energy; collision in fierce car is cushioned, to reach protection passenger's object.
At present, textile for air sacs weaves main employing water jet looms, air-jet loom and Rapier looms.Hardness by the woven textile for air sacs of water jet looms is larger, and the diagonal degree of cloth cover is larger, affects fabric cutting utilization rate.Rapier looms rotating speed is lower, and cost is relatively high.
In Chinese patent Granted publication CN102212960B, described 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 warping and adopts Sizing Technology, wet end furnish and weave the air-jet loom of employing.
At Chinese patent application publication No. CN101984165A, non-coating safe automobile air bag fabric and preparation technology thereof have been described.But this patent does not relate to the kind of slurry, the extraction value of the proportioning of destarch solution, fabric.
Summary of the invention
The present invention adopts air-jet loom, and reasonable disposition starching, desizing obtain 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, yarn easily produces filoplume in air-jet loom weaving process so, and weaving efficiency declines.After starching, if do not adopted desizing, fabric hardens on the one hand, is unfavorable for the good development trend of air bag fabric folding property; 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 is softer during airbag deployment, do not have the effective protection to human body.As the dynamic air permeability < 500mm/s of fabric, when airbag deployment because fabric permeability is little, the energy that gunpowder explosion produces can not distribute in time, easily causes airbag to make position and tears, ruptures.
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, use 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 adopting in described warping starching 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
Deng react the mixture obtaining 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 2.2-2.3,100 ℃ of boiling point >, density 1.14g/m
3.
The vitrification point of new type water-solubility polyacrylate of the present invention is 22 ℃～30 ℃.Owing to containing hydrophilic units structure in slurry, slurry ratio is easier to and water combination, is easier to destarch.22 ℃ of the vitrification point < of slurry, soft in weaving process, sticky phenomenon easily occurs; As 30 ℃ of vitrification point >, after starching, serous coat is too hard, in weaving process, easily from yam surface, comes off, and pollutes.
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 it is 48% caustic soda that NaOH solution weight is wanted chemical composition.Refining agent is mainly surfactant, organic solvent and water.Dispersant main component is the conventional anion based polymer of the art.Bleeding agent main component can be methyl alcohol and ethylene glycol monobutyl ether.
In a concrete embodiment, in described bleeding agent, contain methyl alcohol approximately 4.5%, ethylene glycol monobutyl ether approximately 4%.
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, the yarn of starching is that line density is terylene or the polyamide fibre yarn of 300～600dtex.
According to a further aspect in the invention, the invention provides a kind of safe air bag fabric obtaining according to said method, this safe air bag fabric through, 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, through broadwise pin, to grab intensity be 400～1000N to described safe air bag fabric.
Further, described safe air bag fabric warp, filling-tear resistance are 120～300N.Preferably, described safe air bag fabric through, the preferred > 15ON of filling-tear resistance.Most preferably, described safe air bag fabric through, filling-tear resistance 2OON～300N.
Fabric through, filling-tear resistance > 300N, high to weaving the long filament performance requirement of use, can cause the rising of production cost.As the tearing strength < 120N of fabric, 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.
