METHOD OF DYEING NATURAL FABRIC BY USING NATURAL DYESTUFF AND NATURAL DYED FABRIC DYED THEREBY

摘要

The present invention relates to a method of dyeing natural fabric by using natural dyestuff and natural dyed fabric dyed thereby. According to the present invention, since natural fabric treated by ultrasonic wave is dyed by using natural dyestuff powder of a nanoparticle size, the natural dyestuff is effectively adsorbed to the natural fabric in a short time and dye does almost not come out during washing, so excellent fastness is provided. Moreover, since chemical materials, such as a scouring agent and a mordant agent are not used during dyeing, problems such as environmental pollution, and skin allergy due to chemical materials can be prevented. Therefore, the natural dyed fabric can be used for manufacturing an operating gown, a patient gown, bandage, gauze, clothes for old persons and infants, a diaper, underwear, shirts, a necktie, a scarf, a handkerchief, a blouse, bed clothes, a curtain, a towel, a tablecloth, sportswear, etc.;COPYRIGHT KIPO 2017
