A composite material developed for manufacturing thermoformed products has applications in furniture making, automotive industry, etc. The composite material for thermoforming is made of a thermoplastic fibrous component consisting of 4-60 mm long and 7-16 DEN polypropylene fibers representing 40% to 50% of the total material weight, and a plant fiber component which can be hemp, jute, sisal, coconut, etc., or a mix of natural fibers which is 70-80 DEN and 5 to 100 mm in length and represents 60% to 50% of the total material weight. Manufacturing the composite material comprises proportioning the components, followed by mixing and coarse defibering, then fine mixing in a four-chamber module which also opens the natural fibers to 70-80 DEN, followed by the consolidation of the fibers and rolling of the resulting fabric in a roll. The machinery for manufacturing the composite material has a modular structure, comprising two modules (1 and 2) for feeding the components, two modules (3 and 4) for weighing and proportioning the components, a primary mixing and coarse defibering module (5), a module (7) for fine mixing and fiber opening, an interlacing module (8), and a module (9) for pulling and rolling the final fabric.

The present subject matter provides an antimicrobial cleaning cloth, including: nonwoven fabric fibers; and copper fibers. A method for manufacturing the antimicrobial cleaning cloths includes: mixing nonwoven fabric fibers and copper fibers; carding the nonwoven fabric fibers and copper fibers; cross-lapping the nonwoven fabric fibers and copper fibers; needle-punching the nonwoven fabric fibers and copper fibers to form a nonwoven fabric comprising copper fibers; slitting the nonwoven fabric comprising copper fibers to form nonwoven fabric sheets; winding the nonwoven fabric sheets to form nonwoven fabric sheet rolls; and cutting the nonwoven fabric sheet rolls to antimicrobial cleaning cloths. A system for manufacturing the antimicrobial cleaning cloth and additional embodiments of the antimicrobial cleaning cloth, the method of manufacturing the same and the system for manufacturing the same are disclosed herein as well.

A manufacturing method includes: a step for producing a batt of fibers, elongated in a longitudinal direction, by batting with interlacing of the fibers, a step for passing the batt of fibers, in the longitudinal direction, through a loop-forming device having a set of rotary discs and stationary loop-forming elements, so as to generate undulations, and, following the passing step, a step for bringing the batt of fibers onto a conveyor equipped with brushes, and accumulating the undulations in the brushes so as to achieve a predetermined density.
