Preparation method of a fabric

A preparation method of a fabric, the method comprising:

• obtaining bio-based synthetic fiber chips from textile waste materials, wherein the bio-based synthetic fiber chips include polyethylene terephthalate chips and nylon chips;
• recovering polyethylene terephthalate and nylon from textile waste materials;
• depolymerizing the polyethylene terephthalate into dimethyl terephthalate;
• reacting the dimethyl terephthalate with bio-based-MEG to obtain polyethylene terephthalate chips;
• depolymerizing the nylon into adipic acid;
• reacting the adipic acid with bio-based 1, 5-pentane diamine to obtain nylon chips;
• obtaining extruded filaments from the polyethylene terephthalate chips and the nylon chips through a spinning solution;
• and
• weaving and interlocking the extruded filaments with bio-based elastic fibers to obtain the fabric,
• wherein the spinning solution comprises ethyl carbamate, TiO2, diethylene glycol, acrylonitrile-butadiene-styrene, carbon black and a tackifier.
