Abstract

Insulating material is made from sheets made from chopped fabric or tape or materials assembled in random order and which are partially bent to enhance their elasticity and preservation of voids between the particles. The particles are used as a coherent bonded layer either alone or supported on or between sheets of fabric and anchored by adhesives or stitching. Esp. claimed to make linings or padding for clothing, bedding (e.g. sleeping bags) by stitching together two sheets of material with their insulating layers face to face. The particles are less flammable than expanded polystyrene, less irritant than mineral fibres, and result in layers of lower thermal conductivity than layers assemble led from flat particles. The stock material, as sheet, is compact for storage prior to being creased and chopped.

Description

-1- 20496 / Vk / iy £
Applicant: University College Cardiff, Cardiff, Wales, Great Britain.
Short designation: Insulation material.
The invention relates to an insulating material. The invention further relates to an object containing this insulating material and or a method for manufacturing such an object.
In particular, the invention relates to insulating materials for thermal insulation with high reflective properties. Various insulating materials are known, such as a fiberglass mat or blanket, rock wool or foamed plastic materials, but these materials all have certain drawbacks. Foamed plastic materials, such as foamed polystyrene, for example, are easily flammable unless expensive fire retardant materials are used in the starting component mix. These conventional materials are largely dependent on the insulating properties of the limited air movement, while the materials developed within the scope of the invention moreover have a heat reflection.
With regard to glass fibers and rock wool, it can be stated that both these materials tend to irritate the eyes and on the operator's skin. It is also well known that the glass fibers cause internal irritation in the nose and lungs of an operator unless he is wearing an appropriate ice mask.
One of the objects according to the invention is to obtain an insulating material that reduces or overcomes the above-mentioned drawbacks, so that an insulating material is obtained which can be used without danger.
The investigations made have resulted in an insulating material which is characterized in that it consists of a random arrangement of elements of which at least a part is deformed so that the resistance of the elements is increased and spaces are formed between the neighboring elements in the random ranking. The term "element" mentioned in the description is used and refers to wires of different cross-sections and shapes such as a circular, rectangular or square shape, strips of uniform or non-uniform width and / or thickness, flakes and plates of regular or irregular geometrical shape and of uniform or non-uniform thickness and the like. The elements can be made of metallized, which usually has an oxide layer as surface, or non-metallized, natural or synthetic layered material in the form of a film or film. Examples of metallized elements are metallized polyester, metallized PVC or metallized paper such as fire resistant paper. If desired, a mixture of metallized and non-metallized materials can be used.
The deformation can be accomplished by stretching a part of an element beyond the elastic boundary, by making the whole material or part thereof, for example a corner part of an element, corrugated by embossing, creasing or perforate.
When using a film or film which, as mentioned, may be metallized or non-metallized, layers thereof can be crushed and deformation performed before, during or after comminution. When a metallized or non-metallized film or film is used, its physical properties have been found to be such that ripples are naturally obtained at one or both ends of the strip-like element formed when the film or film is formed by a conventional shredder machine By varying the thickness of the film or film, the width or the strip-like element and the degree of pressure formation, the physical properties of the lifting element can be varied.
Such conventional paper shredding machines are known and widely used for destroying documents and elements produced from this material have the advantage of having good resistance or reforming properties when crushed and they have a relatively large volume. The metalized coating can be aluminum or other suitable metallic material. The thickness of the metallized coating can be up to 1 micron, the substrate film or film having a thickness of up to 50 microns, and the width of the comminuted elements can be small, typically 7 microns and up to 1 cm.
30 It has been found that the thermal conductivity of a 5 cm thick sample
O
of 300 A aluminized 12 ^ PVC with an element width of 1 mm and packing 3.2 h density of 7.5 kg / mf 1.04 W / m C is for a non-metallized sample with the same overall thickness, element width and packing density, the thermal conductivity is 30¾ greater than that of the metallized sample, clearly indicating the advantage of the heat reflecting surface.
. ^ 7901401 *.,? * 4% • -3- 20496 / Vk / iv
It has also been found that the thermal conductivity of a 5 cm thick sample of a fireproofed newspaper with an element width of 1 mm 3 2.0 at a packing density of 50 kg / m is 0.92 W / m C. When packaged in a 300 A aluminized 25 / iPVC coating or envelope, the conductivity is reduced to 0.90 W / m ° G.
These insulation values can be compared with the thermal conductivity of a 5 cm thick sample of a glass fiber mat which has a conductivity of 1.02 W / m ^ ° G and a further improved thermal conductivity as a value is obtained using the insulation according to the invention. when the widths of the elements are reduced to less than 1 mm.
The insulating material according to the invention can be used for insulating roof spaces and the space between walls for residential houses and other buildings and can also be used as a filling material for movable and fixed partition units.
Furthermore, the aluminized plastic elements are highly effective beam-reflecting interfaces with an infrared reflection value of more than 95%.
Because the heat loss from radiation is more than half of the total heat loss by a human body to the environment under calm air conditions, the metallized plastic threads are very effective in reducing heat loss from the body and can be used for thermally insulating clothing .
When controlling the production process, the properties of the resilient, insulating composite of aluminized elements can be varied to meet, for example, the needs of certain applications, especially longer elements can lead to an interwoven mat with such properties that they are easily is manageable and can be applied so that it is directly suitable as a filling material in the manufacture of insulating clothing. Shorter elements give a product with comparable flow properties so that a blow-fill process can be used, for example, for filling sleeping bags.
The thermal conductivity of a 5 cm sample of 300 λ aluminized 12 / * m PVC with an element width of 1 mm at a packing density of 3 2q 7.5 kg / m is 1.02 W / m C, which is advantageous can be compared with the conductivity of a pure duck down with a comparable overall thickness of 2 * 35, which has a value of 1.11 W / m C, a down-feather mixture containing a 7901401% -4- 20496 / Uk / iv has a conductivity of 1.32 W / m ^ ° C and polyester fibers that have a conductivity of 1.40 W / m ^ ° C.
An advantage of the insulating material according to the invention compared to down and other alternatives is that it is not necessary for the manufacturer to have a large amount of belly-shaped material in stock. It can reduce storage space by stocking compact rolls of the aluminum-coated plastic film or film and forming the elements when requested. The manufacturer also has an operation with various options in that he can choose the type 10 plastic film used in accordance with the client's wishes and adapt it to the requirements set by law.
The material can be processed in a protective infrared, transparent cover or the individual elements can be coated so that it can be resistant to various washing operations. 15 - The feel of the material can be improved by treating the elements with a plasticizing material with the conventional plasticizers and lubricants commercially available such as Dow Corning "Fiber Fill" (RTM).
Furthermore, the elements can be used as a filler in padded or non-padded garments such as jackets and other types of clothing.
The elements can also be used as filling material for sleeping bags. In such cases, the elements have the advantage over the conventional filler materials that they are not hygroscopic.
Usually, the coating or stuffing articles are often quilted in order to obtain a fairly even distribution of the filler material such as. for example down, all over the object. Conventional padding processes must be performed with the necessary care when the filler material is applied and are therefore time consuming and expensive. Various padding patterns and methods of performing the padding 30 are known, but in general there are always loot-shaped spots where the stitching completely passes through the padded article. In some cases, there is no insulation or padding at the hump-shaped places consisting of two superimposed layers of the covered material, in others. the insulating material or filling material is strongly compressed at the hump-shaped places, whereby the insulating effect is considerably reduced and 7901401 t -5- 20496 / Vk / iv * so-called cold places are effected.
It has been found that these so-called booty or cold places can be avoided by producing a sub-composition consisting of a layer of the insulating material superimposed and stitched to a layer of natural or synthetic fabric. The stitching can be performed according to a certain desired pattern and applied to that side of the insulation remote from the fabric layer, so that the stitching can be done by an assembly of tapes in accordance with the desired stitching pattern. The tapes provide means for reinforcing the stitching lines and also serve to hold the insulating material in place.
This operation is repeated and the thus-stitched semi-finished products are superimposed, so insulating material on insulating material, and finally hemmed along the circumference to form the padded article. In such a construction, the insulating elements of each component are naturally bonded together so that separation of the two constituent elements is prevented. If desired and to protect against splitting the two elements, they can be stitched together at certain distances from each other.
Preferably, the quilting stitching lines run parallel to each other and at right angles to the general direction of the insulating elements laid on the fabric layer. When two such semi-finished products are superimposed to form a quilted whole, the stitching lines in the two semi-finished products are applied at right angles to each other.
It has been found that using the same mass of elements per unit area of material (20 g per ft. With a ft. = 30.48 cm) and the padding is performed using different techniques so that a height-varying object is obtained with a variable insulation value. Perpendicular to the quilted quilted material with a space between the stitching of three gives a material with a thickness of 16 mm and a conductivity of 3.03 W / m 2 ° C. According to the second method of perpendicular stitching with the double-sided padding with the same padding space, a height of 24 mm is obtained with a conductivity of 2.18 W / m ^ ° C. This clearly indicates the advantage of the double-sided padding technique.
Although particular reference has been made to the application in which elements or wires 7901401-620696 / Vk / iv are produced by comminuting materials and forming them into cushions, the material is not limited to such articles. An element layer can be used as a filler between two layers of a rigid material which may or may not have thermal insulation and heat reflective properties. On the other hand, the elements can be used to fill bags of fabrics and thus form a flexible layer with an insulating material.
While the elements can be fabricated by a grinding operation *, they can also be fabricated by cutting strip from a roll of film or foil applied to a pivot or rotatable shaft.
The strip can then be obtained continuously or discontinuously. It is also possible not to deform a flat element. subjecting it to a heat treatment in order to effect a wave formation and a random arrangement of elements has a related resilient effect.
By applying the method according to the invention and the materials obtained herein, it is possible to obtain building materials, clothing and clothing articles in which the insulating material is incorporated.
