采用硝酸铜酸性媒染法对羊毛织物进行除臭染色。前和后媒染的影响进行了检查，为C. I。媒介黄3和C.I. 17.第十七章羊毛纤维中的羧酸基团和染料对铜离子起固定作用，具有除臭的作用。在Teddler袋中测量媒染织物从空气中消除的有害物质。未经处理或未经媒染染色的织物没有表现出除臭能力，但那些预媒染或媒染前后的织物表现出相当大的除臭能力。通过控制染浴的pH值为4左右，织物的染料和铜离子吸收最佳，除臭能力也最佳。
Wool fabrics with a deodorant function are prepared by acid mordant dyeing with copper(II) nitrate. The effects of pre- and after-mordanting are examined for C.I. Mordant Yellow 3 and C.I. Mordant Red 17. Carboxylate groups in the wool fibers and the dyes work to fix copper ion with the deodorant ability against mercaptan. The elimination of mercaptan from the air by the mordant dyed fabrics is measured in a Teddler bag. Fabrics untreated or dyed without mordanting show no deodorant ability, but those pre-mordanted or pre- and after-mordanted show considerable deodorant ability. By controlling the pH of the dyebath to about 4, dye and copper ion uptake of the fabric is optimized and the deodorant ability is also optimum.
