The present invention relates to a nonwoven fabric including a conjugated fiber containing 40% by mass or more and 80% by mass or less of a propylene homopolymer (A) having a melting point (Tm-D) measured by a differential scanning calorimeter (DSC) of higher than 120° C., 4% by mass or more and 40% by mass or less of a polypropylene-based resin (B) having a melting point (Tm-D) measured by a differential scanning calorimeter (DSC) of 120° C. or lower, and 10% by mass or more and 55% by mass or less of a polyethylene-based resin (C), wherein the nonwoven fabric has a texture uniformity of 2.1 or more and 3.0 or less and a bulkiness of 450 μm or more.

Nonwoven fabric and method for manufacturing same

The method for producing a resin composition of the present invention includes a step of obtaining a lignin-containing solution that contains a solubilized lignin prepared through a treatment of separating lignin in a lignin-containing solution and a solvent, and a step of adding a resin to the lignin-containing solution to thereby obtain a lignin/resin-containing solution. Also, the method for producing a resin composition of the present invention includes a step of mixing the lignin/resin-containing solution with at least one solvent selected from water and a hydrocarbon having a dipole moment of 0.25 d or less. The lignin-containing resin molded article of the present invention uses the resin composition obtained according to the production method of the present invention.
