Definitions

  • the invention relates to a textile fabric for the production of protective clothing, in particular clothing for stab, cut, splinter and projectile protection.
  • Aromatic polyamide fibers have proven themselves very well for the use of protective clothing, especially for protection against stab, cut, splinter or projectile injuries.
  • the World Fencing Federation has prescribed the use of fencing vests made of aromatic polyamide fibers in order to avoid the serious injuries that occur repeatedly when practicing this sport (High Performance Textiles, Volume 8, No. 3, p. 14).
  • Protective clothing made of aromatic polyamide fibers has proven to be extremely reliable in preventing injuries, particularly in body protection against gunshot and splinter injuries during military, police and disaster operations.
  • polyolefin fibers especially polyethylene fibers, which are produced using the gel spinning process, application.
  • Aromatic polyamide fibers have some disadvantages when used in protective clothing.
  • the yellow inherent color of the aromatic polyamide fibers has a disruptive effect in many areas of application. Dyeing these fibers is possible with restrictions, but it does not help in all cases to cover the intrusive color of the aromatic polyamide fibers.
  • protective clothing is usually made from aromatic polyamide fibers in such a way that the protective fabric made from aromatic polyamide fibers is covered with an outer material made from fibers that can be easily colored, printed or optically brightened, in order to achieve an aesthetic appearance of the clothing.
  • the protective layer made of aromatic polyamide fibers is provided with an outer fabric made from a fabric made from polyester-cotton yarns (High Performance Textiles, Volume 8, No. 3, p. 14).
  • This cover layer in the form of an outer fabric over the actual protective layers also fulfills other tasks, namely the protection of the aromatic polyamide fiber against damage by light radiation.
  • the aromatic polyamide fiber suffers a loss of strength when exposed to intense light.
  • an outer fabric made of, for example, natural fibers the wearing comfort of protective clothing is increased.
  • a wound yarn which consists of a core made of aromatic polyamide or another fiber suitable for this, such as, for example, gel-spun polyethylene fiber and a sheath composed of easily dyeable, printable and optically lightenable natural or chemical fibers or mixtures thereof.
  • a wound yarn which consists of a core made of aromatic polyamide or another fiber suitable for this, such as, for example, gel-spun polyethylene fiber and a sheath composed of easily dyeable, printable and optically lightenable natural or chemical fibers or mixtures thereof.
  • the use of wound yarns for the production of the textile fabrics according to the invention makes it possible to process yarns made from aromatic polyamide fibers in a way that is much more gentle and thus less loss of strength.
  • the serviceability of the protective vests made from the textile fabrics according to the invention is also significantly increased.
  • the production of wound yarns for further processing to the textile fabrics according to the invention is not intended to be restricted to the DREF 3 process. Any other method with which yarns with the same properties can be achieved is equally suitable for the production of yarns for further processing into the textile fabrics according to the invention.
  • a further disadvantage of yarns which have been produced by the DREF 2 process is noticeable during the further processing into the textile fabrics according to the invention in a layer structure which is poorer than yarns of the DREF 3 process.
  • the core and sheath layer is not as clearly separated in the case of yarns which have been produced by the DREF 2 process as in the case of yarns from the DREF 3 process, that is to say the core and sheath layer run in the case of DREF 2 - Yarns interlock more than with DREF 3 yarns.
  • This disadvantage of the DREF 2 process is particularly noticeable in areas of application where very good protection of the core substance against light radiation is required.
  • the core substance of the yarns which are used for the production of the textile fabrics according to the invention preferably consists of aromatic polyamide fibers.
  • These fibers often referred to in the short form as aramid fibers, are generally known in the textile industry under brand names such as Twaron. They have proven themselves very well, especially when used for clothing that is intended to protect against stab, cut, splinter or projectile injuries.
  • polyolefin fibers particularly polyethylene fibers produced by the gel spinning process
  • polyethylene fibers produced by the gel spinning process can also be used to form the core.
  • Mixtures of these fibers for example mixtures of aramid and polyethylene fibers, can also be used.
  • the fibers for the core substance can be used both as filament yarns and as spun yarns. Which of the two forms is chosen depends on the desired yarn properties. In the production of yarns for further processing into protective clothing, filament yarns are preferred as the core substance, since filament yarns can achieve higher strength values than spun fiber yarns.
  • the filament and yarn titer for the core material.
  • the selection of the yarn titer depends on the article to be manufactured. Finer titers are preferred to coarser ones.
  • the filament yarns in the core can be used twisted or untwisted. Untwisted yarns are preferred because the core yarn is rotated anyway when spinning using the DREF 3 process.
  • Spun fibers are used to form the shell substance. These can be natural or chemical fibers or their mixtures.
  • synthetic fibers such as polyester, polyamide or polyacrylonitrile fibers.
  • synthetic fibers such as polyester, polyamide or polyacrylonitrile fibers.
  • mixtures of synthetic fibers and cotton or viscose staple fibers in the interest of good wearing comfort.
  • a known mixture that is used very frequently in other articles is e.g. the combination of 50% cotton and 50% polyester staple fibers.
  • wool alone or in a mixture with viscose or synthetic staple fibers, can also be used.
  • the fiber to be used for this is in the form of a stretch belt with a belt weight of 2-3 g / m submitted to the spinning apparatus.
  • This conveyor belt is manufactured with the help of machines that are common in the three-cylinder spinning mill.
  • cotton it is advisable to use combed cotton.
  • Fiber blends can be produced using the blending processes customary in spinning technology.
  • the so-called flake mixture is expedient, but it is also possible to mix the conveyor belt, with several stretching passages having to be carried out in the interest of a homogeneous distribution of the mixing partners.
  • Fibers with a stack length of 30-60 mm are particularly suitable for spinning using the DREF 3 process. Such fibers are offered in a variety of forms by man-made fiber manufacturers. When using cotton, it is also possible to use fibers with a shorter staple length.
  • wool is used to form the coat, it is processed on the machines of the three-cylinder spinning mill.
  • the name wool short combs has become common for tapes made of wool that are manufactured on this machine range. If wool is used in a mixture with a chemical staple fiber, the fiber length of the mixing partner is selected accordingly. Chemical staple fibers with a stack length of 60 mm have proven themselves well in this area.
  • the core material against the action of light rays it is expedient to cover the core of aromatic polyamide fibers with a double jacket. It is particularly well suited an inner jacket made of polyester fibers and an outer jacket made of cotton or viscose spun fiber.
  • This double sheath substance is produced by running a drawstring made of, for example, polyester staple fibers into the spinning unit together with the aramid yarn provided for the core, and forming the outer sheath with cotton or viscose staple fiber in the manner customary in the DREF 3 process.
  • Fig. 1 the production of wound yarns with a double jacket is shown schematically.
  • An aramid filament yarn 2 is drawn off from a bobbin 1 and fed to the spinning apparatus 6.
  • a drawstring 3, which consists, for example, of polyester staple fibers, is drawn off from a can (not shown), stretched on the drafting device 4 and brought together with the aramid filament yarn 2 in front of the pinch rollers 5.
  • the yarn passes through the spinning apparatus 6, which consists of the perforated drums 7 and 7a. Both drums contain suction inserts, not shown.
  • the fibers of the drawstring 3 are wrapped around the aramid filament yarn 2 as a result of the false twist that arises in the gusset area above the suction drums and thus form the inner jacket.
  • the stretch belts 8a-8e which consist, for example, of cotton, are fed from opening cans (not shown) to the opening rollers 9 and 9a and dissolved into individual fibers.
  • the number of belts fed to the opening rollers can be varied as desired.
  • the 5 bands mentioned here are only to be understood as an example.
  • the dissolved fibers are sucked in by the perforated drums 7 and 7a and are wrapped here as an outer sheath around the aramid filament yarn 2 already spun with the fibers from the drawstring 3.
  • the end of the spinning apparatus Yarn 10 is fed to the take-off unit 11.
  • the false twist triggered by the clamping that occurs here fixes the sheath fibers. Conversely, these fibers fix the false twist generated on the core yarn. In this way, the yarn 12 wound with a double jacket is produced.
  • FIG. 2 shows the cross section of the yarn 12 produced on the apparatus described.
  • an inner jacket 14 which in this example consists of polyester spun fibers and an outer jacket 15, in this example made of cotton, placed.
  • the invention is not limited to the polyester staple fibers mentioned here for the inner jacket and to cotton for the outer jacket.
  • the choice of fiber material for the two cladding layers is determined by the properties desired for the yarn. If, for example, good light protection of the aramid yarn core is desired, it is expedient to use polyester staple fibers for the inner jacket, since these have good light absorption. Polyester fibers with appropriate additives are particularly suitable. Matted polyester staple fibers have also proven to be very suitable. These usually contain titanium dioxide, which has an absorbing effect, especially in the UV range. In the same way, other fibers with similar properties can be used.
  • the main criteria for choosing the fibers to form the outer sheath are comfort and easy dyeing, printing or optically brightening.
  • cotton or viscose staple fibers or their blends are very useful here, but blends of cotton or viscose staple fibers with synthetic staple fibers can also be used here come. Even when using viscose staple fibers, matt types that contain spun-in titanium dioxide are preferred.
  • the spun yarns with a core of aromatic polyamide fibers or other suitable fibers or mixtures of these fibers with aramid fibers and a single or double sheath made of fibers that can be easily colored, printed or optically brightened are further processed into textile fabrics.
  • Textile fabrics are to be understood as meaning fabrics, knitted fabrics, knitted fabrics, sewing agents, laid scrims, etc. Which method is chosen for the production of flat fabrics from wound yarns depends on a number of different aspects, from which the desired properties of the protective vests to be made from the flat fabrics are of particular importance. For example, it has proven expedient to provide knitted fabrics such as knitted fabrics or knitted fabrics instead of fabrics if a special elasticity of the vest to be produced from the textile fabrics is required. Threads have proven to be particularly inexpensive because of the low manufacturing costs and the gentle processing of yarns made from aromatic polyamide fibers. However, the latter advantage cannot be given increased importance when using wound yarns.
  • the number of threads to be selected depends on the titer of the thread used and on the type of protective clothing to be manufactured.
  • the yarns are used in a titer range of 200 - 4000 dtex.
  • a yarn count of 9-12 threads / cm is selected with a yarn titer of approximately 850 dtex. With a titer of approx. 1300 dtex the thread count is 7-10 / cm and with a titer of approx. 1700 dtex 6-9 / cm. This information refers to fabrics that are made in plain weave.
  • the plain weave has proven useful, but also other weaves, for which as examples the twill and the Panama weave can be used.
  • the sheathed layer of the wound yarn also provides protection for the aramid core during processing on textile machines and thus makes a significant contribution to maintaining the favorable strength properties of the aramid yarn during its further processing.
  • the textile fabrics according to the invention can be dyed, printed or optically lightened using the methods customary in textile finishing.
  • fencing vests for example, the color white is common.
  • the fibers used for the coat have to be bleached and optically brightened.
  • the bleaching of the sheath fiber should be done appropriately before spinning in the flake.
  • Piece bleaching is also possible, however, due to the oxidizing agents that are almost always used for bleaching, damage to the aramid core must be accepted during piece bleaching.
  • Whether bleaching is necessary at all depends on the fiber used to form the coating substance. In the case of cotton and wool, this is necessary in the interest of a good degree of whiteness, in many cases the man-made fibers already produced with good whiteness do not require the bleaching process.
  • the producers of man-made fibers also offer so-called bright white types. These contain optical brighteners that are spun in or applied in the aftertreatment. When using synthetic fibers or their mixtures, it is advisable to use such types.
  • a yarn with a double jacket shows an advantage of the viscose staple fiber over the cotton when used to form the outer jacket.
  • Treatment of the textile fabrics according to the invention with optical brighteners presents no problems. This treatment can take place in the flake, for example after bleaching the cotton, but it is also possible to lighten the piece goods optically.
  • the processes for this are known in the textile finishing industry.
  • the choice of a suitable product and the treatment conditions depend on the fibers or fiber mixtures selected for the sheath substance.
  • Clothing for splinter, bullet or cut protection is either dyed or printed.
  • the latter is common especially in military use.
  • dyeing and Printing on the textile fabrics according to the invention are well known in the textile finishing industry. The selection of the dyes and the treatment methods depends on the type of fiber or fiber mixture used for the covering of the wound yarns as well as on the desired fastness properties and any other desired properties, such as camouflage colors for protective clothing in the military sector. Dyeing in dark shades is particularly favorable with regard to protecting the aramid core against damage from light radiation.
  • Whether the dyeing is limited to the sheath layer or whether the aramid core yarn is also dyed depends on the desired effect and the yarn construction.
  • Aramid fibers have an inherent yellow color. If a yarn with a simple sheath is used, the yellow color of the core material may shine through in some yarn constructions. In some areas of application, this can be disruptive. In such cases, it is possible to dye the aramid core yarn with disperse dyes.
  • the high-temperature process known in the textile finishing industry under the abbreviation HT process, is suitable for this purpose, with dyeing temperatures up to 135 ° C. in the same way as the dyeing process with carriers. Both methods are well known in dyeing technology.
  • the textile fabrics according to the invention are processed in one or more layers.
  • single-layer processing there is a particular advantage of the textile fabrics according to the invention, since sewing with an upper and possibly a lower material can be omitted, which is not only easier to dispose of the materials to be kept in stock also has a very cost-effective effect during the assembly process.
  • Fencing vests, which are produced from the textile fabrics according to the invention also show considerable advantages over the conventional fencing vests in terms of comfort, which is particularly true for the single-layer processing of the textile fabrics manufactured according to the invention.
  • a fencing vest made without the use of an outer or lower fabric fits snugly on the body of the athlete and thus offers optimal freedom of movement.
  • Protective vests for bullet and splinter protection must be built up in several layers.
  • the conventional way of working is to sew together several layers of fabrics made from aromatic polyamide fibers. This package out several of these fabrics are placed in a shell made of coated fabric, for example cotton. An upper and lower fabric made of colored or printed cotton is placed over the wrapped package formed in this way and the vest is made up in such a way that the package can be removed for cleaning the outer shell.
  • the textile fabric according to the invention is used for the cover placed around the fabrics made of aromatic polyamide fibers. Compared to the coated fabrics used hitherto, this has the essential advantage that the loss of antiballistic effect caused by the coating does not take place here.
  • the textile fabric according to the invention can also be used for the upper and lower fabric. In addition to the simpler disposition option for the materials to be kept in stock, this offers the advantage that, in comparison to the cotton fabric previously used for this purpose, with the textile fabric according to the invention a higher ballistic protective effect of the vests and moreover a better strength can be achieved.
  • layers made of metal fabrics can also be used in the actual cut protection package.
  • the shell of these packages and the upper and lower fabrics what has already been said about protective clothing for bullet and splinter protection applies.
  • the actual cut protection layers can consist of the textile fabrics according to the invention.
  • the use of the textile fabrics according to the invention for clothing for stitch, cut, projectile and splinter protection thus offers considerable advantages with regard to easier disposition in the materials to be used for this purpose, since the storage of the required articles can be significantly reduced.
  • it is possible to achieve significantly better usage properties of the protective clothing by a substantially lower loss of strength in the manufacture of the textile fabrics and by the replacement of cotton fabric with less strength by the textile fabrics according to the invention.
  • the wearing comfort is significantly improved compared to the protective clothing previously used.

  • the yarn thus obtained was made into a woven fabric in plain weave.
  • the number of threads in warp and weft was 7 / cm each.
  • the fabric was produced on a rapier weaving machine.
  • the tissue obtained was dyed dark green. Vat dyes were used for the cotton outer coat and disperse dyes for the polyester inner coat. By dyeing at 135 ° C., the disperse dyes used also stained the core of aromatic polyamide, but the depth of the color was significantly lighter than that of the polyester inner jacket.
  • the fabrics produced in this way were further processed into a splinter protection vest, these fabrics being used for the outer and lining layers instead of conventional cotton fabrics.
  • a vest was made that consisted of 14 layers of conventional aramid fabrics, each weighing 190 g / m2.
  • the fabrics produced according to the invention with a weight of 283 g / m 2 formed an additional outer or inner layer.
  • This vest was subjected to a shattered fire under the conditions of STANAG 2920.
  • the coating was carried out with 1.1 g splinters.
  • a V50 value of 476 m / sec was achieved when the dry package was bombarded. This value means that there is a 50% probability of penetration at this speed.
  • the corresponding value was 456 m / sec.
  • the vest is stored in a vertical position in water for one hour before being bombarded and is subjected to the bombardment test after a draining time of 3 minutes.
  • the comparison material consisted of a vest which was also made up of 14 layers of aramid fabric, each weighing 190 g / m2.
  • the upper and lower fabric consisted of a cotton fabric with a weight of 272 g / m2. With this vest, the V50 value was 455 m / sec when bombarded in the dry state and 428 m / sec when bombarded in the wet state.
  • the fabric from Example 4 was used to manufacture a bullet-resistant vest.
  • 20 layers of aramid fabric with a weight of 280 g / m2 were used.
  • the fabric produced according to the invention formed two additional layers each on the outside and on the inside. These layers once served as cover for the picture the so-called ballistic package, on the other hand as an upper and lower fabric.
  • This vest had a total of 24 layers: from the outside in, the vest consisted of the following layers: 2 layers of the fabric according to the invention, 20 layers of aramid fabric, 2 layers of the fabric according to the invention.
  • the test of the vest which was produced on a trial basis, was carried out in comparison to a vest which consisted of 24 layers of aramid fabric with a weight of 280 g / m 2 and a layer of coated polyester fabric on the outside and inside of the ballistic package and as top or Cotton fabric had under fabric. So this vest had a total of 28 layers. From the outside in, the vest consisted of the following layers: outer fabric made of cotton fabric, coated polyester fabric, 24 layers of aramid fabric, coated polyester fabric, lining made of cotton fabric.
  • the bullet test was carried out according to the NIJ standard. In both cases, the projectile used for the bombardment did not pass through the protective vest.
