Abstract
The invention relates to air bag fabric with fewer falbalas and a production method thereof, wherein the air bag fabric is high in tensile failure strength. The air bag fabric comprises a ground texture and two side textures and is characterized in that the ground texture is made of filaments large in fineness, the two side textures are made of filaments small in fineness, and the fineness difference between the ground texture and the side textures is 15.0-30.0%. The ratio of the falbalas height to the fabric breadth length is smaller than or equal to 4%, and the number of the falbalas of the fabric is smaller than or equal to 5/meter. The production method of the air bag fabric is further provided. The air bag fabric is fewer in falbalas, high in tensile failure strength and even in physical property.
Description
Technical field
The present invention relates to textile for air sacs and the production method thereof of few, the high tension failure brute force of flounce.
Background technology
Expand as utilizing gas etc. when colliding and absorb the air bag of mitigation to the impact of human body, except driver's seat use and co-pilot seat air bag, curtain type gas bag, installing side airbag, knee air bag, rear seat bags etc. are practical and in order to protect passenger.
At present, weaving of textile for air sacs mainly adopts water jet looms, air-jet loom and Rapier looms, comparatively large by the filament fineness of the woven textile for air sacs of above-mentioned loom, easily produces flounce when weaving, that causes textile for air sacs produces difference through broadwise physical property, affects the utilization rate of fabric.
Patent publication No. CN101608371B describes the precursor that weaving process adopts two kinds of different fineness, but its objective is the slippage resistance improving fabric, and precursor to arrange in weaving process be adopt certain rule (the large long filament of fineness and the little long filament of fineness alternately), do not relate to flounce to improve, and adopt the program effectively can not improve flounce.
Summary of the invention
Textile for air sacs of the present invention, fabric adopts the long filament of two kinds of different thicknesses, the long filament that fabric ground tissue fineness is thick and the long filament that both sides Selvage Stitch adopts fineness thinner, and the two difference in fiber fineness rate is 15.0-30.0%, the flounce height of this fabric and fabric width length ratio≤4%, flounce number≤5/meter of this fabric.If fabric does not adopt the long filament of two kinds of different thicknesses, then effectively can not reduce flounce.If the long filament that fabric ground tissue fineness is thick and the long filament that both sides Selvage Stitch adopts fineness thinner, the two difference in fiber fineness rate is less than 15.0%, then to improve effect little for flounce; If the two difference in fiber fineness rate is greater than 30.0%, then selvedge easily produces fold.If flounce height and fabric width length ratio are greater than 4%, and number is greater than 5/meter, then fabric count is comparatively large to physical difference, can not be equal to use, cause fabric effective rate of utilization to decline when cutting through broadwise fabric.
Textile for air sacs of the present invention, both sides Selvage Stitch is 30 ~ 80 with the radical compared with fine filament, is preferably 40-60 root.If the radical < 30 piece of each Selvage Stitch compared with fine filament, then due to radical very little, can not effectively improve warp tension in one's ear, the flounce height of fabric and fabric width length are than > 4%, and the flounce number > 5/meter of fabric.If the radical > 80 piece of each Selvage Stitch compared with fine filament, then because radical is too many, the stressed larger overbending of fabric ear limit yarn volume, fabric is easily wrinkling at coiling process in one's ear.
Textile for air sacs of the present invention, the tensile break strength of fabric warp-wise is: 400 ~ 800N/cm, and the tensile break strength of broadwise is: 400 ~ 800N/cm.If the warp of fabric, broadwise tensile break strength > 800N/cm, then can be high to the long filament performance requirement weaving use, the rising of production cost can be caused.If the tensile break strength < 400N/cm of fabric, then air bag explosion time, fabric can not bear the impulsive force that high-temperature high-pressure air flow produces, and easily ruptures, effectively can not play the protective effect to human body.
Textile for air sacs of the present invention, the filament linear-density of fabric is 250-700dtex, and containing 60-144 root monofilament in long filament.The fiber number of long filament is too high, then the fabric thickness be made into is excessive, and just softness is high, not foldable and the potential of injury is existed to protection personnel may; If fiber number is too low, then the mechanical performance of the fabric be made into can not be guaranteed, and production efficiency is low, increases manufacturing cost.
Textile for air sacs of the present invention, its long filament is Tynex or polyester filament, is preferably nylon66 fiber long filament.Tynex has that initial modulus is low, good springiness, hot melt high.Its fabric has under Dynamic Loading that stress distribution is even, absorbability is strong, shock resistance is good, heat resistance and the advantage such as anti-flammability is better.In addition, good, long-term the folding of nylon fabrics flexibility not easily becomes fragile.Particularly nylon66 fiber has good heat resistance, and intensity is high, has suitable ductility, and softness is good, thus obtains immense success in this market of air bag.
The invention still further relates to a kind of processing method of textile for air sacs, comprise the following steps: tissue long filament preparatively; Prepare both sides Selvage Stitch long filament; Described organizing is woven into plain weave with long filament and described both sides Selvage Stitch long filament; And post processing is carried out to described plain weave, it is characterized in that: when HEAT SETTING fabric width sets, described Selvage Stitch section sets is outside pin tooth, and organize the long filament adopting fineness thick describedly, the long filament that described both sides Selvage Stitch adopts fineness thinner, and the two difference in fiber fineness rate is 15.0-30.0%.
If Selvage Stitch part is not set in outside pin tooth, then can cause physical difference in fabric clipping region, affect air bag performance.
