Definitions
- the present invention relates to a method for producing fabrics, in particular airbag fabrics, using a multi-phase or row shed weaving machine.
- a row shed weaving machine with a weaving rotor which is equipped with an insert and stop combs, which combs warp threads with the insert combs on a periphery from an loading station to a stop in the form of compartments when wefts are made in the compartments a weft processing be fed, and which strikes the inserted wefts with the stop combs on the stop of the fabric formed.
- the object is achieved with a method according to claim 1.
- This has the advantage that the weft density is increased as it were with the use of a shrinking yarn type in the warp direction in the finishing process by hydraulic and / or thermal shrinking.
- the shrinking movement during hydro and / or thermal shrinking takes place asymmetrically at the binding points in such a way that the finished fabric has symmetrical thread densities in the warp and weft and consequently, in addition to the air permeability, the rest physical properties - same as the conventionally produced fabric - in both thread directions.
- a raw material that is asymmetrically woven on the row shed weaving machine is converted into a symmetrically constructed textile surface that meets the requirements for tightness and symmetry for airbag fabrics.
- the method according to claim 1 is advantageously further developed by using filament yarns with 8-14% hot air shrinkage as the warp and filament yarns with 1-5% hot air shrinkage as the weft.
- the use of these types of yarn resulted in extraordinarily good, uniform fabrics in the end product, which are particularly suitable for use as airbag fabrics.
- the fabric consisting of filament threads in warp and weft is produced on a multi-phase weaving or row shed machine according to the weaving concept that can be gathered from WO 96/38 610.
- the weft is inserted in series, in four shed compartments formed one behind the other by air nozzles at constant speed and thus without tension peaks.
- the staggered weft threads are guided in the weft channel by the rotor movement to the goods edge.
- the lower compartment which appears there lifts the partially integrated weft thread out of the weft channel over the entire weaving width and is struck by the following stop comb.
- the asymmetrically woven fabric is formed into a symmetrical fabric during the finishing process due to the asymmetrical shrinking processes in the end product.
- the shrinking movements at the binding points that occur during finishing take place asymmetrically in such a way that the finished fabric has symmetrical thread densities in warp and weft, and consequently, in addition to the air permeability, also has the other physical properties in both thread directions.
- an asymmetrically woven raw fabric becomes a symmetrically constructed textile surface.
- the weft insertion performance is more than doubled compared to the shaft weaving technology with air jet weft insertion, without including the disadvantages of the less tightly knit weft threads due to the process technology, since the unevenness after Finishing process, as explained above, is resolved.
- the method according to the invention can also be used to produce a uniform fabric, which can be used in particular for airbags, on a modern row shed weaving machine - and this with full utilization of the advantages possible by the row shed weaving process.
