(54) Insulating material


(57) Insulating material manufactured from raw materials obtained from recycled rugs and carpets as well as from production wastes, i.e. from natural wool fibres mixed with vegetable and synthetic fibres. Material consists of recycled rug and carpet fibres as well as of recycled production waste fibres.


Description


[0001] The present invention relates to insulating mat and acoustic mat as an insulating material for building industry.

[0002] Insulating mat is known according to a patent application No. 315656. It contains mineral fibre layer made of single, elementary mineral fibre material and such mineral fibres are joined together with a binder and for a mineral fibre layers are generally arranged in a plane basically vertically to a mat plane. Moreover, this mat contains shield permeable to air guarding at least prevailing part of two main mat surfaces and shield is connected with this mat.

[0003] Nature of the invention is an insulation material made of natural wool fibres, vegetable and synthetic fibres recovered from recycled carpets and rugs.

[0004] Insulating material made of recycled rug and carpet fibres does not raise a dust during installation and use. It doesn't cause any allergy. If operational conditions (temperature and humidity) are met then this material is capable to absorb humidity without any dimension changes. It is possible to use a thermo-insulation mat again without any additional processing.

[0005] Insulating material is made of recycled rug and carpet row materials and of recycled production wastes, i.e. is made of natural wool fibres mixed with vegetable and synthetic fibres.

[0006] Insulating material consists of recycled rug and carpet fibres and recycled production waste fibres. Composition of material already manufactured is: 60% - recycled rug and carpet fibres, 25% - polyester fibres, and 15% - thermo-shrinkable fibres, fibre thickness from 80 mm to 150 mm, density from 20 kg/m3 to 40 kg/m3.

[0007] Another composition example: 40% - recycled rug and carpet fibres, 20% - recycled production wastes, 20% - polyester fibres, and 20% - thermo-shrinkable binding fibres.


Claims

1. An insulation material consisting of recycled rug and carpet wastes and of fibres obtained from recycled natural production waste raw materials.
 
2. Material as in Claim 1 wherein composition of it is 60% recycled rug and carpet fibers and 25% polyester fibres and 15% thermo-shrinkable connecting fibres.
 
3. Material as in Claim 1 wherein composition of it is 40% recycled rug and carpet fibers and 20% recycled production waste fibres and 20% polyester fibres and 20% thermo-shrinkable connecting fibres.
