Definitions

  • This invention is about the heat barrier that prevents the heat transfer, allows removal of the body moisture while preventing the ingress from the liquid and provides full protection against the heat stress when exposed to elevated temperatures.
  • This invention is especially about the protective, respirable, watertight, inflammable fabric that prevents the heat transfer when exposed to elevated temperatures and provides full protection against heat stress.
  • This invention is developed for use in clothing capable of resisting excessive heat. It provides protection in areas exposed to elevated temperatures in particular for clothing of the firefighters.
  • the protective clothing like the clothing for the firefighters is in general consisted of an exterior fabric, heat barrier and interior fabric.
  • the biggest problems faced by the firefighters are the extreme heat generated, heat stress and the skin burns as a result of contact with the fluids used to extinguish and suppress the fire.
  • the conduction is the transfer of heat by direct contact of the heat with an object.
  • the convection is the transfer of heat via a medium (like air).
  • the thermal radiation is, however, the transfer of the heat in the form of the light energy.
  • the water is a poor insulator and it transfers heat even without a contact.
  • Wet protective clothing increases the risk of injury via conducted heat. Therefore, it is extremely crucial for a fabric to be watertight.
  • Another type of conduction heat injury occurs as a result of rapid transfer of the heat on the surface through the layers of the clothing, since there is no air between the layers. This generally causes injuries on knees and arms. Therefore, the layers of the fabric should not be too close to each other.
  • the convection heat transfer makes the heat to be felt even if there is no direct contact with the flame. Therefore, the protective clothing should be used, even if there is no contact with the flame or very hot objects.
  • Thermal Radiation is a type of heat transfer, where the heat is conveyed from hot objects in the form of the light energy. Thermal Radiation may also take place if there is a latent heat. In such cases, the burns are likely, even if the temperature is only 80 degrees. Therefore, it will be necessary to use protective clothing against thermal radiation.
  • This invention eliminates the heat stress. It has long service life.
  • the barrier subject of this invention does not deteriorate the mobility when used as interior layer. It provides conform during use. It is watertight. Furthermore, it is inherently moisture/steam permeable. It is inflammable.
  • This invention is more effective compared with other barriers. It is cost effective, flexible, light and more durable even if it provides high degree of insulation. Furthermore, other heat barriers contain arimide nonwoven fabric. This, however, gives rise to various problems. The product subject of this invention, however, incorporates woven or nonwoven active carbon.
  • This invention is developed to be used for clothing capable of resisting excessive heat.
  • clothing provides protection against excessive heat and elevated temperature generated upon a fire, flame, explosion and the like.
  • This invention introduces multi-layer fabric.
  • the fabric provides sufficient time to escape from the fire and delays the heat transfer. It provides comfort even under extremely elevated temperatures.
  • the fabric is consisted of multi-layers, however it is still light, flexible and durable. It does not catch fire. It is comfortable, does not prevent mobility, and does not permeate the liquids; however it allows steam and air diffuse through it, features high strength, durable, can be washed, reduces heat stress and provides heat insulation.
  • this special fabric prevents the heat stress.
  • the intermediate layer greatly reduces the heat the inner layer is exposed and reduces heat while expelling body moisture through the gap it provides, which ensures the air circulation.
  • the number of the layer or density of the fabric might be increased.
  • the invention is comprised of exterior fabric (1), membrane (3), barrier fabric (6), intermediate fabric (7) and interior fabric (4).
  • Exterior fabric (1) is made from inflammable material, since it may come into direct contact with the flame. Exterior fabric (1) may be made from either metaaramide, paraaramide, PBO (Poly-p-phenylene benzobisoxazole), PBI (Polybenzimidazole), carbon, inflammable viscon (FR viscose), inflammable polyester or mixture of these in braided, woven or nonwoven form.
  • PBO Poly-p-phenylene benzobisoxazole
  • PBI Polybenzimidazole
  • carbon inflammable viscon
  • FR viscose inflammable polyester or mixture of these in braided, woven or nonwoven form.

  • Barrier fabric (6) may be made from braided, woven or nonwoven metaaramide, paraaramide, PBO (Poly-p-phenylene benzobisoxazole), PBI (Polybenzimidazole), carbon, inflammable viscon (FR viscose), inflammable polyester or the mixture of these.
  • Intermediate fabric (7) may be made from metaaramide, paraaramide, PBO (Poly-p-phenylene benzobisoxazole), PBI (Polybenzimidazole), carbon, inflammable viscon (FR viscose), inflammable polyester or their mixtures in braided, woven or nonwoven form, which can create gap in between.
  • PBO Poly-p-phenylene benzobisoxazole
  • PBI Polybenzimidazole
  • carbon inflammable viscon
  • FR viscose inflammable polyester or their mixtures in braided, woven or nonwoven form, which can create gap in between.
  • interior fabric (4) may be made from paraaramide, PBO (Poly-p-phenylene benzobisoxazole), PBI (Polybenzimidazole), inflammable viscon (FR viscose), inflammable polyester or their mixtures in braided, woven or nonwoven form.
  • PBO Poly-p-phenylene benzobisoxazole
  • PBI Polybenzimidazole
  • inflammable viscon FR viscose
  • polyester inflammable polyester or their mixtures in braided, woven or nonwoven form.
  • 2-layer heat barrier comprised of woven active carbon or nonwoven active carbon fabric (2) is formed by laminating membrane (3) that will expel the body moisture and prevent the ingress of the fluids. Its overall specific weight is about 160 ⁇ 25 gr/m 2
  • 3-layer heat barrier consisted of woven active carbon or nonwoven active carbon fabric (2) is formed by laminating membrane (3) that will expel the body moisture and prevent the ingress of the fluids and combining silicone extrusions (5) to woven active carbon or nonwoven active carbon fabric (2).
  • the silicone extrusions (5) are heat resistant and installed homogenously. Silicone extrusions (5) are about 0.5 ⁇ 2.0 cm apart and extending to 0.5 ⁇ 2.0 cm from the surface of the fabric. These extrusions (5) ensure the circulation of the air by creating air gaps between exterior fabric (1) and barrier. This provides ventilation. It delays the transfer of the hot air to come into contact with the body and ensures more effective protection by reducing the stress caused by the hot air. The insulation is enhanced thanks to the extrusions (5). Its overall specific weight is about 225 ⁇ 25 g/m 2 .
  • the durability of 2-layer heat barrier (1) and 3-layer heat barrier (2) up to 300 degrees are tested.
  • the firefighter clothing can be produced by making use of arimide as exterior fabric (3), 2-layer heat barrier (1) or 3-layer heat barrier (2) and arimide as interior fabric (4) ( fig.1 and 2 ).
