This application describes a method of preparation of a natural graphene cellulose blended spunbond nonwoven fabric, which comprises using a graphite powder as a raw material for preparing a graphene solution, adding the graphene solution to a slurry formed by mixing and dissolving a wood pulp with N-methylmorpholine N-oxide (NMMO), removing the water content thereof to form a spinning dope, and then directly preparing the natural graphene cellulose blended spunbond nonwoven fabric by a spunbond process. The present method does not require a highly toxic hydrazine hydrate solution. Further, by increasing the adding ratio of the graphene solution in the manufacturing process, control of the antistatic properties and thermal transferring function can be achieved, and thereby various requirements of different consumers can be satisfied. Besides, the fabric can decompose naturally after being used, and thus the product is harmless, natural, and environmentally friendly.

A system and method for creating mycelium textile materials is disclosed, in which leftover, cutoff, and other materials used to create the textile materials that would otherwise be discarded are further used in a second process to create bonded mycelium boards. The system and method further reuse or recycle materials throughout the process of creating the mycelium textile fabric and bonded mycelium boards, thus keeping waste to a minimum.

According to an example aspect of the present invention, there is provided a process for the production of a cellulose filaments or films, comprising the steps of dissolving a cellulose substrate in an ionic liquid consisting of the superbase cation 7-methyl-1,5,7-triazabicyclo[4.4.0]dec-5-enium [mTBDH]+ and an anion to produce a solution forming a spinning dope, said anion being derived from an acid which is present at a stoichiometric excess to the superbase, extruding the spinning dope through a spinneret in a coagulation bath containing water to form filaments or films from the solution, withdrawing ionic liquid in an aqueous mixture with water from the coagulation bath, recovering the ionic liquid [mTBDH][OAc] from the aqueous mixture by removing water and optionally recycling the recovered ionic liquid to the dissolution step.
