Definitions
- the invention relates to a fabric or knitted airbag for safety, coated, and to a process for obtaining it.
- the invention relates more particularly to a fabric or knitted airbag for safety, coated, obtained without gluing step or washing step, from threads having a determined quantity of lubricating composition present on their surface.
- the invention also relates to the use of these threads in the field of coated airbag fabrics or knitwear, as well as an airbag comprising the coated fabric or knitted fabric.
- a twisting operation is generally carried out on them.
- this twisting operation is increasingly being replaced by a pneumatic process of interlacing the filaments.
- the number of cohesion points can be varied, that is to say the number of points at which the filaments form a knot, depending on the final appearance. desired for the wire and its subsequent use.
- oils or sizing agents are commonly applied. With regard to artificial and synthetic continuous yarns, these oils or sizes are applied to the yarn one or more times during its production process. These oils or sizing products are generally removed after weaving by treating the fabric, during a washing operation. Indeed, the presence of these oils or sizing products can be harmful, in particular in the field of inflatable safety bags; for example, they can reduce the adhesion performance of the fabric to the protective coating, as well as the fire and temperature resistance properties of the bags.
- This well-known treatment by its application on yarns of fibers to ensure the cohesion of the fibers and to form a protective sheath of the yarn, is also applied to continuous artificial and synthetic multifilament yarns; the sizing must ensure the retention and protection of the filaments, generally of fine, therefore fragile titles, and surround the continuous threads with a sheath avoiding the friction described above and thereby facilitate sliding both on the looms and between threads, in order to produce fabrics without appearance defect, and avoiding breakage as much as possible and scuff marks.
- These sizing products are generally removed after weaving by treating the fabric, during the desizing operation.
- the desizing operation also allows the elimination of oils and sizing products present on the wires; the washing operation mentioned above is in this case carried out during the desizing operation.
- the sizing product can be difficult to remove completely, depending on the type of product used, the type of thread, and the texture of the fabric, which may cause the presence of glue residues in the tissue.
- the presence of these residues can prove to be harmful, in particular in the field of airbags; for example, it can reduce the performance of the product during its aging as well as its fire and temperature resistance properties.
- fabrics having an elastomeric protective coating layer - for example silicone resin - there are two basic types of fabrics for airbags: fabrics having an elastomeric protective coating layer - for example silicone resin -, and fabrics having no elastomeric protective coating layer, in particular for weight reasons.
- the protective bags are formed by a canvas of synthetic fiber, for example of polyamide (Nylon®), covered on at least one of its faces with a layer an elastomer of the choloroprene type.
- the “airbag” (or airbag) is an airbag made of polyamide fabric, folded and tight. The presence of such a layer or such a protective coating is dictated by the fact that the gases released by the gas generator (for example: carbon monoxide, NOx) in the event of impact, are extremely hot and contain glowing particles which may damage the Nylon ® bag.
- Protective silicone coatings are also used; they are generally obtained by coating the substrate then hardening resulting from the polyaddition of the unsaturated groups (alkenyls, eg Si-Vi) of a polyorganosiloxane on hydrogens of the same or of another polyorganosiloxane.
- the internal protective layer of elastomer and the synthetic fabric support, forming the walls of the "airbag" must in particular be perfectly adherent, and withstand high temperatures and mechanical stresses. Inflatable bags must in particular have good properties of resistance to fire and temperature, as well as good resistance to crumpling and abrasion (“scrub test”).

- the average proportion of lubricating composition by weight relative to the weight of the base fabric or knitted fabric corresponds to the average proportion of lubricating composition present on the surface of the threads forming the basic fabric or knitted fabric, by weight relative to the weight of the threads.
- each thread forming the fabric or knitted fabric has a proportion of lubricating composition on its surface between 0.3 and 0.9 (limits included)% by weight relative to the weight of the wire.
- a proportion of lubricant composition less than 0.3% can make it difficult to spin and / or weave yarns, fibers, filaments, in particular in the case of weaving without sizing.
- a proportion of lubricant composition greater than 0.9% could degrade the final properties of the coated fabric, in particular the resistance to wrinkling and abrasion (“scrub” test).
- the proportion of lubricating composition on the surface of the wires can be measured according to any method known to those skilled in the art, such as an extraction method or an NMR method.
- the proportion of lubricating composition is measured by an extraction method, according to standard DIN 54278. These measurements can be carried out on threads or on fabric or knitted fabric.
- the lubricating composition present on the surface of the wires can be a sizing composition, and / or a waxing composition ("warping oil" in English).
- the lubricating composition is a sizing composition.
- a sizing composition, applied to yarns, fibers, filaments during their production process, makes it possible to facilitate their sliding.
