Abstract
A layered fabric for nuclear, biological and chemical protective clothing comprises a supporting fabric 1, adhesive layer 2 and an activated carbon-woven fabric 3 all bonded together by hot melt lamination and an external fabric 4 sewn thereon. A soft, flexible, porous and permeable three layer fabric may be provided.
Description
THREE LAYER FABRIC FOR NUCLEAR
BIOLOGICAL AND CIIEMICAL CLOTHINGS
TECHNICAL FIELD
This invention concerns the perfect bonding of an activated carbon-woven fabric with a supporting fabric by hot melt method and by sewing the external fabric thereon with the desired features provided so as to produce a soft, flexible, porous and permeable three layer fabric for nuclear, biological and chemical clothing which provides protection against nuclear, biological and chemical weapons.
THE KNOWN STATUS OF TECHNIQUE
Today, the activated carbon grains in form of black cumin are used in fabrics against nuclear, biological and chemical weapons. Such activated carbon grains are easily dispersed off the fabric because it is difficult for them to catch on the surface.
DESCRIPTION OF THE INVENTION
This invention overcomes the above disadvantages, with its feature to provide bonding of an activated carbon-woven fabric and a supporting fabric with one another by hot melt method. Such supporting fabric, adhesive layer, formed by providing the external fabric with many features such as non-inflammability, water tightness, gas permeability, oil tightness, respirability is then specially bonded with an activated carbon-woven fabric to increase its utilisability, making it a most suitable one according to the place of use.
The invention is characterised such that the activated carbon-woven fabric is a soft, flexible, porous, permeable one in form of straight and long/narrow and long/perforated micropre being much lighter relative to activated carbon grains and having the feature of higher draw and catch on the surface. An activated carbon-woven fabric has an excellent tensile strength and durability. Furthermore, it has non-inflammable, anti/alkali wear-resistant, non-corrosive, anti-bacterial, non-toxic, odorless and renewable characteristics.
The combination of supporting fabric, adhesive fabric and the activated carbon-woven fabric formed on the invention constitutes the absorbant part. While being prepared for use, the external fabric with such absorbant part thereof provided with several features according to customer's request (various colors and designs, different compositions, oil tightness, water tightness, wind resistance, non-inflammability, gas permeability, crease proofness, respirability and other features) is assembled by a special sewing method.
Particuarly its water tightness feature is used; because when the activated carbon-woven fabric gets wet, its filtering characteristics decrease.
On the invention, protection against toxic chemicals is achieved by use of proper substances in the absorbant part. Furthermore, thanks to its air permeability, the clothing can also be worn for a long period of time and thanks to its temperature adjustment, it can also be used under different climatic conditions. The field of use of the clothing is widened by providing the external fabric with proper physical characteristics. It can be worn on some other dress and it can be used to replace the formerly used clothings which provide protection against nuclear, biological and chemical weapons by way of insulation.
It is preferrable in the fields of military defence and civil defence.
Thanks to its activated carbon fibers fabric by hot melt method used, the invention provides very effective and long-term protection against nuclear, biological and chemical weapons.

SHORT EXPLANATION OF DRAWINGS
Figure 1: Layered view of the invention Figure 2: Diagrammatic view of the invention
EXPLANATION OF THE INVENTION
The invention is composed of a supporting fabric (1), adhesive layer (2), woven fabric (3) and external fabric (4).
The supporting fabric (1) is a woven or knitted one.
In the adhesive part of the adhesive fabric (2), polyester, polyamide, EVA, reactive urethans, pressure-sensitive adhesives or other adhesives are used. The adhesive should remain gas permeable or a perforated layer after adhering process as well.
The woven fabric (3) is a fabric woven from activated carbon, with absorbant part thereof being perforated and uniform. This fabric also removes and disposes alliphatics, hydrocarbons, halogenes, aromas, aldehydes, ketones, acids, alcohols, phosphorus compounds, ethers, esters, sulphur and nitrogen compounds as well as hydrogen suiphite, sulphur dioxide, chlorides and formaldehydes.
For the external fabric (4), a camouflage printed fabric can be used; however, it may have oil-tight, water-tight, wind resistant, non-inflammable, gas impermeable, crease proof, etc. features by the proper techniques used and with variable composition in various colors and designs according to customer's request.
The supporting fabric (1), adhesive layer (2) and activated carbon fibers fabric (3) are bonded by hot melt lamination method. After binding, the external fabric (4) is combined thereon by special sewing.
Claims (2)
1. A layered fabric for nuclear, biological and chemical protective clothing comprising a supporting fabric, adhesive layer and activated carbon fiber fabric, all bonded together by hot melt lamination, and an external fabric sewn thereon.
2. A layered fabric according to Claim 1 characterised in that the activated carbon fibre fabric is woven and is effective to absorb and/or remove alliphatics, hydrocarbons, halogenes, aromas, aldehydes, ketones, acids, alcohols, phosphoms compounds, ethers, esters, sulphur and nitrogen compounds as well as hydrogen suiphite, sulphur dioxide, chlorides and formaldehydes.
