    • PURPOSE: To produce the titled molding, small in loss of strength and excellent in color fastness, by dyeing a polyester molding grafted with an acid group- containing vinyl monomer and converting the acid groups into alkali metal salts.
      CONSTITUTION: A polyester molding is immersed in a swelling agent (e.g., monochlorobenzene) containing an organic peroxide such as benzoyl peroxide to introduce the organic peroxide into the inside of the molding. This molding is immersed in an acid group-containing vinyl monomer (e.g., acrylic acid) and heat-treated to graft the molding with the vinyl monomer. Thereafter, this molding is dyed at high temperature (130W135°C) and high pressure; immersed in an aqueous solution of an alkali metal salt (e.g., NaOH), and treated at 80°C or below to convert the acid groups into salts of the alkali metal.

    • 目的:通过染色用含酸基的乙烯基单体接枝并将酸基转化为碱金属盐的聚酯模塑制造标题成型品,强度低,色牢度优异。 构成:将聚酯模塑浸渍在含有有机过氧化物如过氧化苯甲酰的溶胀剂(例如一氯苯)中以将有机过氧化物引入模制品的内部。 将该成型体浸渍在含酸基的乙烯基单体(例如丙烯酸)中,进行热处理,以使乙烯基单体接枝成型体。 此后,将该成型品在高温(130-135℃)和高压下染色; 浸入碱金属盐(例如NaOH)的水溶液中,并在80℃或更低温度下处理以将酸基转化成碱金属盐。
