The invention pertains to a method of manufacturing a product from used woven or knitted textile comprising vegetable or animal fibres, in particular cotton or wool, the method comprising the steps of: collecting the used woven or knitted textile, granulating the used woven or knitted textile into fibres having an average fiber length of between 3.6 mm and 5.5 mm, mixing the granulated used woven or knitted textile with a thermoplastic fiber based binder, and forming a nonwoven mat from the mixture of the granulated used woven or knitted textile and fiber based binder, the nonwoven mat comprising 59% to 75% of vegetable fiber, or alternatively the nonwoven mat comprising at least 80% animal fibres. The invention also pertains to a product produced by said method.
D04H 1/54 - Non-woven fabrics formed wholly or mainly of staple fibres or like relatively short fibres from fleeces or layers composed of fibres without existing or potential cohesive properties by welding together the fibres, e.g. by partially melting or dissolving
D04H 1/58 - Non-woven fabrics formed wholly or mainly of staple fibres or like relatively short fibres from fleeces or layers composed of fibres without existing or potential cohesive properties by applying, incorporating or activating chemical or thermoplastic bonding agents, e.g. adhesives

The invention pertains to a method of manufacturing a product from textile waste comprising a majority of cotton or wool, the method comprising the steps of; collecting the textile waste comprising; a majority of cotton or wool, granulating said, textile waste into fibers having an average fiber length of between 0.5 mm and 4 mm, mixing said granulated textile waste with thermoplastic binder, and forming a nonwoven mat from the mixture of said granulated textile waste and binder. Preferably the method further comprises the steps of placing said: mat in a preheated three-dimension mold or flat press, and pressing the mat into a product having a shape determined: by the shape of the three-dimensional mold or flat press. The invention also pertains to a product produced by said method.
