Method of producing rigid package material and rigid box from textile waste

A method of producing a rigid package material from textile waste, the method comprising:

• mechanically shredding the textile waste into fibres having length from 0.2-8 mm, the textile waste comprising at least 40% of synthetic textile;
• blending the fibres with a binder having a melting point 120-200° C., wherein the blended fibres comprise 60-70% of the shredded textile waste fibres and 40-30% of the binder;
• arranging the blended fibres into a nonwoven web having thickness of 5-30 mm;
• needle punching the nonwoven web to form a nonwoven felt with an areal density of 500-3000 g/m2 and thickness of 5-20 mm;
• and
• pressing the nonwoven felt thermomechanically at a pressure of 100-250 bars to obtain the rigid package material having thickness of 1-3 mm, wherein the pressing is carried out at a temperature of 120-150 C.
