摘　　要：优化了天然染料菱角壳的提取工艺,并分别采用酒石酸常温浸轧和加热浸渍预处理真丝织物,研究了酒石酸用量对真丝织物白度和印花效果的影响。研究发现,菱角壳色素提取时氢氧化钠最佳质量浓度为10 g/L。酒石酸对真丝预处理的优化条件为:常温浸轧时,酒石酸质量浓度为10 g/L,二浸二轧,轧余率75%;加热浸渍时,酒石酸质量分数为1%(omf),浸渍温度为40~50℃,时间30 min。酒石酸常温浸轧预处理后的印花效果为最佳。The extraction conditions of natural dye from water caltrop outer peels are optimized, and two pretreatment methods containing room temperature padding and warm dipping are applied to silk fabrics by using tartaric acid, and the whiteness and printing effects of silk fabrics are tested. The optimized concentration of sodium hydroxide for the extraction of natural dye from water caltrop outer peels is 10 g/L. The two pretreatment conditions with tartaric acid are defined as follows： by room temperature padding, the concentration of tartaric acid is 10 g/L using a double-dip-double-nip process with a pick-up of 75%; by warm dipping, the concentration of tartaric acid is 1%（omf） with a temperature range of 40-50 ℃ for 30 min. It is said that room temperature padding pretreament can impart the silk prints with excellent properties.
