The invention relates to a woven or knitted material of inflatable air bags with coating, and method of its production. In particular, the present invention relates to a containing coating woven or knitted material airbags obtained without phase smoothing and without a washing step of the threads containing on its surface a certain amount of the lubricating composition. The invention also concerns the use of these fibers in the area containing coating woven or knitted materials airbags and inflatable air bags, containing woven or knitted material is coated.

To provide adhesion of the yarn intended for weaving, as a rule, they are subjected to a twisting operation. However, this operation twisting increasingly replace pneumatic way weave elementary fibers. Thus, depending on the pressure of the fluid and means to weave, you can change the number of points of coupling, i.e. the number of points on the level of elementary fibers form a node, in accordance with the desired final appearance of the thread and its further purpose.

To facilitate the sliding of the fibers and yarns are often put oil or grease. As for artificial or synthetic is practical fibres and yarns, the oil or lubricant composition is applied to the floss one or more times during its production. As a rule, after smoothing by treating the fabric of these oils or lubricating compounds are removed during the washing operation. Indeed, the presence of these oils or lubricating compounds may be undesirable, in particular, in the manufacture of airbags; for example, they can reduce the adhesion characteristics of the fabric with a protective coating, as well as the properties of fire resistance and heat resistance of the pillows.

While using basics, mainly in the weaving industry, as you know, the threads rubbing, on the one hand, each other during movement of the lifting and lowering shaft and, on the other hand, about the elements of the machine, such as the eyes of the shafts, through which they pass, needles warping combs, Bataan, reel, Savostianov etc. So that friction did not lead to defects that are detrimental to the operation of the textile and quality of the fabric, the yarn is subjected to pre-treatment, called dressing. This processing is well known for its use in fiber yarn to provide adhesion of the fibers and produce a protective sheath yarn is also used for artificial and synthetic solid multi-fiber threads; the dressing should keep the and the location and protection of elementary fibers, usually very thin and therefore fragile, and to cover the solid filaments of the sheath, to avoid the above-mentioned friction and facilitate due to this, at the same time sliding on the parts of the machine and between the threads to get the fabric without external defects and to avoid gaps and protestestes. Typically, these sizing substances are removed after smoothing by processing the tissue during the operation of rasshifrovka. Operation rasshifrovka also allows you to remove oils and lubricating compositions of the present threads; in this case, the above-mentioned washing operation carried out during the operation of rasshifrovka.

To save on the cost of operations of smoothing and rasshifrovka and exclude, therefore, the two operations to manipulate threads, it was proposed to abandon the operation of smoothing, which also is harmful to the environment. In addition, slashing the substance can be hard to resist complete removal depending on the type of substance used, the type of yarn and fabric structure, which can lead to the presence of glue residue in the cloth. The presence of these residues is undesirable, in particular in the field of airbags, for instance, it can affect the performance of the product when it is aging, and its fire resistance and heat resistance./p>

Therefore, it was proposed to exclude the smoothing operation and the washing operation during the manufacture of the inflatable cushions personal protection users of a vehicle called "airbag". However, the exception to this stage smoothing and washing should not worsen, and to preserve the required properties of the tissue using, for example, an inflatable airbags.

There are two types of base fabrics for airbags: fabrics, containing a layer of protective coating of elastomer, such as silicone resin, and fabric that does not contain a protective layer of elastomer, in particular, for reasons of reducing weight.

As for the fabric with a protective layer, the air bags were made from fabrics of synthetic fibers, such as polyamide (Nylon®), coated at least on one side with a layer of elastomer type chloroprene. "Airbag or the airbag is inflated air pillow of folded and compacted polyamide fabric. The presence of such a layer, or a protective coating due to the fact that the gases released by the gas generator (for example, carbon monoxide, NOx) in the event of a collision, are very hot and contain hot particles, which can damage the bed of Nylon®.

Also use silicone protective coatings; as a rule, they received the t by drawing on a substrate with subsequent solidification in the polyaddition unsaturated groups (alkylene, for example, Si-Vi) of polyorganosiloxane to the hydrogen atoms of the same or another polyorganosiloxane.

The inner protective layer and the substrate of synthetic fabric forming the walls of the air bags should have, in particular, excellent adhesion and can withstand high temperatures and mechanical stresses. In particular, the airbags should have good fire-resistant and heat-resistant properties and good resistance to crushing and abrasion ("test scrub").

Thus, in particular, to an inflatable airbag with a protective coating made attempts to exclude the smoothing operation and the washing operation during manufacture of the fabric and at the same time to preserve the properties of the tissue, necessary for its use as inflatable air bags, such as fire-resistant and heat-resistant properties and the properties of resistance to crushing and abrasion ("test scrub").

In this regard, the first object of the present invention is containing the coated woven material, or knitted material)obtained by applying to the base fabric or knitted material) elastomer, at least on the surface of the base fabric (knitted or material), and the thread base cloth (or knitted material containing on its surface a certain amount of lubricating composition

The second object of the present invention is a method for containing the coating woven or knitted material, in particular the way, not containing phase smoothing and washing step.

The third object of the invention is the use of threads containing on its surface a certain amount of lubricating composition intended for the production of woven or knitted material of the inflatable airbag with cover.

The fourth object of the invention is an airbag containing woven or knitted material is coated.

Thus, the first object of the present invention is containing coating woven or knitted material obtained by coating on the base fabric or knitted material of the elastomer, at least on the surface of the base fabric or knitted material, while the base fabric or knitted material made of yarns containing at least part of its surface a lubricating composition, with the average content of the lubricating composition (dry extract) is from 0.2 to 0.7 wt.% (including limits) relative to the weight of the base fabric or knitted material, preferably from 0.3 to 0.7%. The average weight percent of the lubricating composition relative to the weight of the base fabric or trikotajnih the material corresponds to an average mass content of the lubricant composition on the surface of the filaments, forming a base fabric or knitted material, relative to the mass of threads.

According to the private option run woven or knitted material in accordance with the present invention, each strand, forming a woven or knitted material, contains on its surface a lubricating composition in an amount from 0.3 to 0.9 wt.% (including limits) relative to the weight of the yarn. The content of the lubricant composition is less than 0.3% can complicate the process of spinning and/or weaving yarns, fibers, elementary fibers, in particular, in the case of the textile without smoothing. The content of the lubricant composition in excess of 0.9% can affect the final properties containing coating fabric, in particular, its resistance to crushing and abrasion ("test scrub").

The content of the lubricant composition on the surface of the filaments can be measured by any known specialists by a method such as the method of extraction or the NMR method. Preferably the content of the lubricant composition is measured by the method of extraction according to DIN 54278. These measurements can be made on the threads or woven or knitted material.

Lubricating composition on the surface of the filaments may be a composition for oiling and/or composition for waxing ("warping oil").

Preferably, the lubricating composition was stock for oiling.

The oiling composition applied to the filaments, fibers, ale is Narnia fibers during their manufacture, allows you to facilitate their sliding. The amount of composition for lubrication in accordance with the present invention, applied to the yarn, fiber or elementary fibers, not only ensures their normal behavior during the operations of spinning, warping and weaving without smoothing, but also allows the fabric for airbags with a good final properties, in particular, in the case covered with silicone fabric for airbags. This coated fabric has particularly good properties of resistance to crushing and abrasion ("test scrub"), it is not necessary to remove the oiling composition present on the surface of the threads of the fabric.

The oiling compositions suitable for carrying out the invention are all compounds oiling, classically used in the spinning of polymers, in particular spinning polyamide or polyester fibers. The oiling composition may contain the following compounds: natural or synthetic fatty acids or derivatives of fatty acids, such as esters of fatty acids as lubricants; non-ionic emulsifiers, such as ethoxylated fatty acids, ethoxylated fatty alcohols or polymer EO/RO; anionic emulsifying agents such as phosphates, sulfates or sulfonates; other additives such as surface-the active substance. Typically, the compositions of oiling are oils or water emulsions.

Composition for waxing ("warping oil)applied to the warp threads, designed for textile, allows to improve the weaving process. For the invention any suitable composition waxing, classically used in the field of textile fibers, in particular polyamide or polyester yarns. Preferably, the composition of waxing as the predominant compounds contained mineral oil with a high flash point, synthetic paraffin or glycerin ether.

The lubricating composition may contain a surface active antistatic substances commonly used in compositions for oiling.

The strands forming the base fabric or knitted material containing coating woven or knitted material in accordance with the present invention can be natural, artificial or synthetic origin. They can also be combined origin: for example, mention can be made of yarn of polyamide and cotton.

Preferably, these strands were obtained from a thermoplastic polymer. For example, as a thermoplastic (co)polymer suitable for use in the framework of the invention, mention can be made of: polyolefins, polyesters, polyoxide of alkylene, polyoxyalkylene, polyhalogen alkylene, poly(alkilinity or terephthalate), poly(family or phenylene), poly(oxide or phenylene sulfide), polyvinyl acetate, polyvinyl alcohols, polyvinylchloride, polyvinylidenechloride, polyvinylidene, polyamides, polyimides, polycarbonates, polysiloxanes, polymers of acrylic or methacrylic acid, polyacrylates or methacrylates, natural polymers such as cellulose and its derivatives, synthetic polymers, such as synthetic elastomers, or thermoplastic copolymers containing at least one monomer that is identical to any of the monomers included in the above-mentioned polymers, and mixtures and/or alloys of all these (co)polymers.

In particular, these copolyamids can be hexamethylen-Poladian is d, polyphthalamide obtained from terephthalic and/or isophthalic acid, such as the polyamide sold under the trade name AMODEL, copolyamids, obtained from adipic acid, hexamethylene-diamine and caprolactam.

Preferably thermoplastic polymer is a polyester, such as polyethylene terephthalate (PET), polypropyleneimine (PPT), polybutylene terephthalate (PBT), their copolymers and mixtures.

Another preferred thermoplastic polymer is chosen from the group of (co)polyamides, including polyamide 6, polyamide 6.6, polyamide 4, polyamide 11, polyamide 12, polyamide 4-6, 6-10, 6-12, 6-36, 12-12, their copolymers and mixtures.

Threads can be made on the basis of a mixture of thermoplastic polymers or thermoplastic copolymers.

Threads may contain additives such as reinforcing fillers, means for fire-resistant impregnation, stabilizers, makes them resistant to UV radiation, matting compounds such as titanium dioxide, bioactive substances, etc.

The total titer of the filaments forming the base fabric or knitted material of woven or knitted material with a coating in accordance with the present invention, it is possible to choose in the whole range of the usual titles of the threads, for example, from 10 dtex to 2500 dtex, preferably from 10 to 1100 decitex. In the field of airbags the total titer of prepact the tion is in the range from 100 to 950 decitex.

Title elementary fiber threads, you can choose in the whole range of the usual titles of the threads. As a rule, the title of the elementary fibers greater than or equal to 0.3 dtex. Usually it is the smaller equivalent in measuring the diameter of 800 microns in the case of elementary fibers of large diameter. In the field of airbags threads are usually multi-fiber, and the titer of the fibers is preferably from 1.5 to 7 dtex.

The strands forming the base fabric or knitted material containing coating woven or knitted material in accordance with the present invention, can be obtained using the method containing the following steps:

1) spinning a filament material

2) if necessary, perform the stretch yarn

3) if necessary, develop the structure of the thread

4) thread process using the above-described lubricant composition.

Step 1) spinning exercise any known in the art.

If the filament material is a thermoplastic polymer, the step 1) is preferably a step of spinning the polymer in the molten state.

The filaments may be subjected to stretching. So, the thread can be pulled along the path of the spinning, using a known method with the necessary degree of stretching, depending on the direction and mechanical characteristics, neobhodimaja make the thread. It can simple pre-dispatch or route during spinning, depending on the final speed winding. It can be obtained directly, or pass through the rollers to regulate the tension of the winding, if this is of interest or is necessary. Step 2 can be performed simultaneously with spinning or separately.

Typically, the speed of winding is in the range from 100 to 8000 m/min, preferably from 600 to 5000 m/min and more preferably from 700 to 4000 m/min

Step 3) formation of patterns can be produced using any known in the art method.

Step 4) processing can be performed before or after the stretching stage, if necessary. Step 4) processing can be performed before or after a possible phase 3) of the formation of patterns. Typically, the composition processing in step 4) is used in liquid form. We can talk in particular about the oil solution, emulsion or other dispersion in a liquid.

In the case of a multi-fiber yarn processing can improve the adhesion between the fibers.

The processing in step 4) can be produced using conventional technologies, such as application using drums or bins. As non-restrictive examples of conventional technologies, you can specify the processing technology of fiber raw on the drum through which aerosole or spraying, by immersion, technology adding, as well as any method used in the textile industry for the processing of synthetic fibres. This processing can be performed at different stages of manufacturing filaments. Among other things we are talking about all the stages during which typically produce fouling. Thus, the additive can be applied in the lower part of the spinning machine before winding. In the case of processes, called "fiber", you can also apply a Supplement before, during or after steps stretching, Curling or drying, etc.

In some cases it may be necessary to implement preprocessing (preprocessing) thread by means known in the art methods in order to improve adhesion of the composition thread. In addition, it is also possible to envisage other types of chemical or physical treatment of the yarn, such as irradiation, dyeing and other, before or after the processing in step 4).

Preferably the base fabric or knitted material in accordance with the present invention has a density in the range of 40 to 400 g/m2. In particular, in the field of airbag fabric contains the number of threads per cm of fabric, comprising from 10 to 30.

Preferably woven or knitted material in accordance with the present invention is applied specification of the N.

The second object of the present invention is a method for containing the coating woven or knitted material for inflatable air bags, containing the following steps:

- textile yarn, containing lubricating composition, at least on its surface, the content of the lubricant composition (dry extract) is from 0.3 to 0.9 wt.% (including limits) relative to the weight of the yarn, while the textile perform on the loom to get basic weft-main fabric, or are knitting these threads for receiving a base of knitted material.

- applied to the base fabric or knitted material of the elastomer, at least on the surface of the base fabric or knitted material.

All that has been said above in respect of the threads forming the base fabric or knitted material containing coating woven or knitted material in accordance with the present invention, can be attributed to the threads of a woven or knitted material.

Yarn used for manufacturing the base fabric or knitted material may be the same or different. The above thread forming at least the base fabric, preferably they simultaneously form the warp and the weft of the fabric.

Threads can be used, for example, as the warp threads on industrial TC is ccih machines. Preferably they allow you to get the fabric without phase smoothing. Preferably they allow you to get the fabric without phase smoothing and washing step.

If yarns are used as warp threads, they can be easily applied either by direct warping, or when the sectional warping without smoothing on all types of weaving machines, in particular on high-speed machines used in industrial scale.

In some cases, for example, when the threads are designed for textile weaving machines, which act on the warp elevated loads, before the implementation of textile preferably produce waxing yarns using any of the commonly used substances.

Preferably the base fabric get on the loom dry steps, such as rapier loom, air jet loom with blower(s) tube(s) or machine with air(and) cylinder(s).

The step of applying elastomer to the base fabric or knitted material known in the art.

The above threads are used, in particular, for the manufacture containing coating woven or knitted materials for airbags, which is a third object of the present invention. Preferably these tissues get without phase smoothing and preferably without a washing step, which simplifies pic is b the manufacture of such products and reduces their cost. The above threads are used, in particular, for the manufacture of woven or knitted materials for airbags, containing a coating of silicone.

In addition, these fabrics can also be obtained without the step of heat treatment. Indeed, typically through the step of heat treatment of fabrics to impart dimensional stability. Typically, this stage of the heat treatment carried out simultaneously with the step of drying the fabric, which is necessary if the fabric passes through the washing step. In the framework of the present invention, if the refuse from the washing step, it is not necessary in the stage of drying. Therefore, the stage of heat treatment can be implemented simultaneously with the next step of the method, in particular, in the case of woven or knitted material for the manufacture of inflatable air bags. For example, it can be done after applying the elastomer to woven or knitted material; preferably it is carried out simultaneously with the step of crosslinking of the elastomer.

The presence of lubricant composition on the surface of the threads does not affect the subsequent processing of the fabric, particularly if the fabric is used as the base fabric containing coating woven fabric for airbags. As an example of such further processing can yasat the application of the elastomer, etc. In particular, do not deteriorate the properties of resistance to abrasion and crushing ("test scrub").

Finally, the fourth object of the present invention is an inflatable air bags, containing woven or knitted material with a coating in accordance with the present invention.

Other details and advantages of the present invention will be more apparent from the following examples.

The coating on the fabric with the purpose of their evaluation

• Using a laboratory spatula on the fabric applied silicone resin, marketed under the name RHODORSIL® TCS 7510 A and In the company Rodhia Silicones. The amount of the applied coating is about 40±10 g/m2(dry extract).

• Coated fabric is weighed to calculate the amount of the coating.

• The sample is then subjected to heat treatment in a drying Cabinet at 180°C for 60 seconds.

• The sample was then removed and left in the air.

• Cut out a sample of size 5 × 10 cm2, which is then tested for Scrub Test.

Test "scrub": determination of resistance to crushing ISO 5981

This test allows to characterize the resistance to crushing and abrasion containing coating fabric.

During this test the fabric are, on the one hand, the shear stress by means of two jaws, clamping two opposite the edge of the sample and driven in a reciprocating motion relative to each other, and, on the other hand, the abrasion due to contact with a moving substrate.

SUBSTANCE: invention is related to textile industry and may be used in shock-absorption devices of transport safety belts, safety belts of erectors and any energy-absorption devices for suppression of impact load, which does not exceed 100 kgf. Woven tape comprises two background layers arranged parallel relative to each other with fixed edges produced by linen interweaving of main and weft threads and joined to each other by system of energy-absorption broken threads, which create cells of triangular shape with each of background layers. Background layers are arranged in single plane and are connected to each other by means of weft threads, which being interwoven with warp threads of each background layer in alternating order, create adjacent discrete woven sections that contain at least 2 linen repeats.

EFFECT: creation of energy-absorption woven tape, which has high evenness of rupture of energy-absorption threads in it.
