The object of the innovation is a multi-layer insulation sheet Made of synthetic material for heat and cold protection purposes, the excellent properties of which make them suitable for numerous purposes make suitable.

Insulation materials are in mat, plate or other form for Heat and cold protection purposes are used and are intended to inhibit the heat transfer, which increases with the temperature difference, or if possible prevent. You will find a multi-layer length of fabric for making items of clothing, sleeping bags and blankets, among other things and the like extensive use, whereby in addition to the insulating effect they also meet the requirements of clothing comfort * such as low weight and suppleness as well as hygiene. For some purposes it is also necessary that the insulation materials are also waterproof.

The known multi-layer insulation materials meet these requirements inadequate or omit various of the above Missing properties at all.

This is the case with a heat-insulating sheet of material for items of clothing and the like. An insulating layer of wadding or fluffy wool between two plastic films embedded in a waterproof manner and sewn to these in such a way that the individual layers come together can shift against each other to a certain extent. The double-sided covering of the insulating layer with waterproof Plastic sheeting, i.e. also on the side close to the body, is unfavorable in terms of clothing hygiene and leaves the insulating layer come only imperfectly into effect.

For others recommended as protection against the cold, made of outer fabric, lining and interlining pieces of clothing are used as interlining a relatively thin, made of each other glued tangled fibers existing, porous, fabric-like fabric used, which is advantageous by pressing the impregnation agent into a non-woven fabric, e.g. with the help of press rollers, will be produced. By gluing and pressing the volume and the bulk of the tangled fiber fleece in each Reduced trap, so that an optimal thermal insulation effect can not be achieved with such a material. In addition, the addition of bonding agents is a for many uses causes undesirable stiffening of the material, reduces its resistance to washing and a chemical Cleaning mostly not allowed.

Furthermore, waterproof fabrics for clothing purposes are known, which are made of rubber or rubberized fabric and or are covered on both sides with a fiber fleece or textile pile. Such outer clothing is not known to be known particularly warmth, and attempts have been made in various ways between the waterproof outer fabric and the lining, i.e.

to create heat-insulating layers of air, e.g. by inserting a mesh intermediate layer or by embossing depressions in a textile impregnated with a binder, which self-contained air cells with the adjacent tissue layer forms, or for example by combining at least one layer of inelastic textile fabric with a cellular body film made of thermoplastic material, which is made up of closed gas cells. All of these constructions largely lack the Flexibility and suppleness necessary for the processing and use of thermal insulation sheets and in many ways Cases the uniform character of a multi-layer fabric, its Components differ materially, structurally and in use Manufactured article sensibly complement and to special effects unite.

It has now been found that multilayer, high-strength, specifically light, waterproof insulation materials made of synthetic material for Heat and cold protection purposes are obtained when a one-sided waterproof and seawater-proof coated high-strength outer fabric made of polyamide continuous yarn with a multi-layer, not glued, voluminous, covered on both sides with knitted fabrics and combined with these, preferably polyester fleece, which is quilted over a large area, a polyamide velor knitted fabric, the width of which is the pile is on the outside, forms the outer fleece cover and that facing the non-coated side of the outer fabric Fleece side with a light knitted fabric made of continuous polyamide threads covered and is firmly connected via this to the outer fabric by gluing. This particularly useful combination Individual measures and components, some of which are known per se, result in a thermal insulation material with a previously unattainable insulating effect and excellent properties.

The thermal insulation material according to the innovation consists of 2 main parts, a waterproof, high-strength outer material and an underlying one thermal insulation layer of extremely low. Warmth-* passage. In a particularly advantageous embodiment the waterproof outer fabric is made of a high-strength polyamide 6 fabric (PERLON TM) »using its construction the titre 210 / 3β denies a lower one with higher strength square meter weight of only 100 g (uncoated). This carrier fabric is made with PVC or a synthetic rubber, preferably based on chloroprene such as neoprene, coated and thereby Made waterproof and seawater resistant, On the chloroprene rubber layer can optionally also have a layer of rubber-like plastic made of crosslinkable, sulfochlorinated Polyethylene (Hypalon Wz.) Are applied. The well-known good properties of this equipment give it that coated outer fabric made of polyamide 6 fabric an excellent Practical value that is retained even after long periods of storage and especially when there are strong changes in temperature ** blelbt, and secures

or gluing the seams when assembling the with this Outer fabric made of thermal insulation material.

The thermal insulation layer connected to the waterproof outer fabric consists of a polyester fleece made of 3 den fibers, the obtained by doubling several e.g. card or brim nonwovens and has a square meter weight of approx. 250 g. The fibers " of the fleece are not glued to each other to increase the volume and the fullness of the fleece and thus its full thermal insulation effect to obtain. The fleece is knitted with polyamide on both sides covered, over a large area (10 χ 10 cm) with and between

this quilted and is thus held together. The pile side is on the underside of the polyester fleece a polyamide velor knitted fabric with a square meter weight of 125 g, which is made from 4o / 18 denier threads. The single capillaries, must not be thicker than 4 den, because in this thickness they have a voluminous velor with particularly good heat retention capacity result. It is essential that it is a real velor knitted fabric and not one caused by roughening with damage of the individual capillaries produced pile. ·

On the uncoated side of the waterproof outer fabric facing side forms the cover of the polyester fleece light polyamide 6 knitted fabric with a square meter weight of approx. 25 g made from a monofilament polyamide 6 thread of 20 denier. This is with the waterproof outer fabric with a permanent adhesive tied together.

The waterproof thermal insulation material built up from 5 layers in this way has a square meter weight of only around 800 g, which is roughly the same as corresponds to a normal jacket material. He owns a very high one Strength of approx. 100 kg in 5 cm strips, as well as great suppleness and flexibility that allows it to be shaped and shaped at will allow and favor its processing. Its thermal insulation capacity is excellent and exceeds that Thermal insulation materials achieved so far. .

The diagram in FIG. 1 shows the time-temperature curves of an envelope-free A or a test body B insulated with the thermal insulation material according to the invention during cooling. The test was done in the manner that a glass flask of 100 cnr filled with water of 45 ° C and then was initially provided without any sheath in running water of 16 ⁰ C. The temperature profile over time was followed with a thermometer that was stuck in the perforated rubber stopper of the flask. The temperature measurements were

then repeated under the same conditions after the flask had been wrapped with the new thermal insulation material. ■

As can be seen from the curves, the nonisolated specimen has accepted the temperature of cooling water of 16 ⁰ C after about 30 minutes, while the temperature of the isolated with the renewal date thermal insulation, water-filled glass bulb itself after 4 hours at about 27 ° C hold. For curve B, this results in a half-life of 187 minutes, i.e. around 15 hours.

The special properties of the insulation material in every respect according to the innovation, such as high strength, low specific weight, water impermeability and high thermal insulation capacity, leave only limited options in the choice of the processed material and constructional options see below Polyester fiber fleece can be exchanged for another lightweight one Synthetic fiber fleece, whereby the fiber titer can be increased in favor of the bulk elasticity, if this is due to the lower specific weight of the material is balanced again, i.e. « the entire insulation material has specifically light fibers based on polypropylene, if necessary in a mixture with other synthetic fibers bäw. in packaging that increases the bulk elasticity .

The thermal insulation material according to the innovation 1st because of its excellent Usage properties and good processing properties are suitable for numerous uses, which up to now have been widely used less good material had to be used and concludes thus a gap in demand. Of the various uses let s »B. called? the manufacture of special clothing for water work, for example when building bridges, deep-sea shipping and deep-sea fishing, canal workers, sport fishermen,
