Definitions

  • the invention relates to a protective suit that is worn when surfaces in confined spaces have to be cleaned by means of sandblasting or similar blasting.
  • Such an application occurs, for example, in filtration systems of industrial plants. Deposits or rust must be removed there.
  • the blasting pressure used which can be up to 1.2 MPa, and through the crampedness of the rooms, which can be as small as 70 cm, made it necessary to protect the employee from the blasting agent being punctured.
  • a protective suit against harmful substances which has a fabric with a waterproof and dustproof coating made of a highly elastic plastic.
  • a protective suit does not meet the requirements in the application described above.
  • the invention is based on the object of creating a comparatively light and/or cost-effective protective suit that satisfies the requirements described at the outset.
  • the protective suit according to the invention has an inner suit and an outer suit that is separate or separable from it, which has a coated outer fabric and an abrasion resistance according to DIN EN ISO 12947-2 (12 kPa) of at least 100,000 tours.
  • the outer suit achieves the necessary protection class, which is guaranteed in particular by the coated fabric. In this way, in particular, good abrasion resistance is achieved.
  • the necessary pressure penetration resistance is also guaranteed.
  • a ballistic or high strength fabric is preferably used for the inner suit.
  • the weight can be more than halved compared to the leather suits currently in use.
  • the maximum weight is 3.5 kg.
  • the measure according to the invention that the inner and outer suit are separate or can be separated from one another also leads to the advantage that typically the inner suit can be washed separately from the outer suit. This also applies to the outer suit, which can also be replaced when worn out, while the inner suit can continue to be worn.
  • the coating of the outer fabric it should be mentioned that it does not have to be waterproof and does not necessarily have to be particularly elastic.
  • the total weight of the protective suit according to the invention being a maximum of 3.5 kg.
  • a ceramic coating has proven to be particularly favorable for the abrasion resistance of the outer fabric.
  • Aramid fibers in particular para-aramid and/or meta-aramid, viscose FR, polyester and/or polyamide are currently preferred for the outer fabric.
  • the outer fabric can also be made flame-retardant.
  • meta-aramid, viscose FR and para-aramid can be mixed.
  • 100% para-aramid is conceivable.
  • a typical basis weight of the first-mentioned fabric is around 340 g/m 2 . If the outer fabric does not necessarily have to be flame retardant, high-strength synthetic fabrics with polyester, polyamide or similar can be used. A fabric with 100% polyester and a weight of about 290 g/m 2 has shown good properties.
  • the preferred basis weight of the outer fabric is 160 to 350 g/m 2 , in each case, just like the above information, without a coating.
  • the outer fabric has at least one elastic section, for example on the sleeve insert, so that good freedom of movement is achieved.
  • Such inserts can be covered by outer fabrics and adjacent outer fabrics can thereby be overlapped, for example over a minimum width of 5 cm.
  • the outer fabric has at least one ventilation slit, for example on the back of the protective suit in the back area and/or on the back of the legs at the level of the knees.
  • ventilation slots can also be provided in the area of overlapping sections of the outer fabric.
  • the inner suit has at least two layers.
  • one layer has a woven fabric
  • a second layer can have a nonwoven or fleece, for example.
  • a net, in particular in the form of a knitted fabric, can also be provided on the inside for ventilation.
  • the inner suit can also improve the Freedom of movement have elastic sections or a total of elastic textiles, woven fabrics, nonwovens or knitted fabrics.
  • 260 to 300 g/m 2 and in particular about 280 g/m 2 are currently preferred. This also applies to the fabric strength according to DIN EN ISO 13934-1 of around 8500 or 8200 N/5cm. Good properties have been found for the fabric of the inner suit when using 100% para-aramid multifilament yarns with a strength of at least 120 cN/tex. At least 100 cN/tex is preferred for the strength of the yarns. Accordingly, HMPE fibers as well as aromatic polyester fibers and, as mentioned, para-aramid can also be used.
  • both the inner and outer suit have a zipper, which is offset from one another, so that they do not lie on top of each other, which would mean a weak point.
  • the zipper of the outer suit can be centered and vertical on the front, while the zipper of the inner suit is offset to the side.
  • the protective suit according to the invention can advantageously be combined with an external ventilation system, which can have perforated hoses, for example, which can be attached to rubber loops on the inside of the inner suit, so that fresh air can be supplied particularly close to the body.
  • an external ventilation system which can have perforated hoses, for example, which can be attached to rubber loops on the inside of the inner suit, so that fresh air can be supplied particularly close to the body.
  • the outer suit 10 of a protective suit according to the invention is essentially designed to cover the entire body of a user, with the exception of the feet, hands and head.
  • a Velcro fastener 12 is provided here, which in the case shown is about 5 cm from the end of the sleeve or leg and is about 3 cm wide.
  • a seam 14 is provided between the Velcro fastener 12 and the end of the sleeve or leg at a distance of approximately 2.5 cm.
  • a sleeve insert with knitted fabric is provided with a width of about 5-70 mm from the edge of the torso as indicated with the dotted line.
  • a zipper 16 is provided at its upper end, in the area of the collar 18.
  • FIG. 2 From the rear view of figure 2 shows that ventilation with a rubber band 20 is provided in the transverse direction in the area of the torso.
  • a ventilation slot with overlapping fabric sections can be provided in the area of this ventilation.
  • the torso overlaps with the respective leg over a width of about 5-70 mm, as also indicated here by the dotted line.
  • Out of figure 3 shows that the outer suit 10 has a second layer, particularly in the area of the back, which is formed by a mesh fabric in a central area 22 and by knitwear in the two outer areas 24 .
  • the inner suit 26 shown results in approximately the same dimensions as for the outer suit with regard to the seams 14 and the sleeve inserts.
  • knitwear is provided in the area of the sleeve inserts.
  • the zipper 16 is offset from that of the outer suit, in the case shown to the left as viewed by the wearer, and a snap button 28 is provided at its upper end.
  • the inner suit also has a mesh fabric in the middle area in the area of the torso and knitwear on each side.
  • the inner suit may otherwise consist of a para-aramid ballistic fabric and a 3D felt, while the outer suit typically consists of a mixture of a para-aramid ballistic fabric and a ceramic-coated fabric.
