20230048697 · 2023-02-16 · ·

A method of applying fragrance to a fabric substrate includes bleaching a cotton fabric substrate, mercerizing the cotton fabric substrate, and preparing the cotton fabric substrate for dyeing. The method includes making a foam containing a bonding material made of an acrylic polymer or a carboxylated, heat-reactive, styrene-acrylic copolymer, a surfactant, water, and microcapsules of a fragrant material in a ratio of about 40% bonding material, about 2% surfactant, about 45% water, and about 13% microcapsules of a fragrant material. The cotton fabric substrate is passed through a foam applicator where the foam is applied to the cotton fabric substrate using a top applicator of a foaming machine to apply the foam to a face of the fabric substrate in a wet-pickup range of 25% to 10%.

SKIN MATERIAL, METHOD FOR PRODUCING SAME, AND INTERIOR MATERIAL

A skin material includes: a design layer; and a base cloth layer. The design layer includes a surface layer and a foam layer. The base cloth layer includes a surface fabric and a back fabric, and a binding yarn that binds the surface fabric and the back fabric. The binding yarn is a thermoplastic resin fiber erected between the surface fabric and the back fabric to form a gap between the surface fabric and the back fabric. The foam layer and the surface fabric are joined. An interior material includes the skin material and a base material to which the skin material is attached. A method for producing the skin material includes joining the surface layer and the base cloth layer via a foamable adhesive to serve as the foam layer.
