我从事染料工业几二十年,由于能力学识浅薄,又因担任工场工作,不能专心研究,对中国染料少有供献,尤其因为政治认识不够,妨碍了我的进步。通过了三反五反运动后,最近又参加共同纲领的学习,伟大的毛泽东思想启示我,使我思想上起了波动及转变,确立了新的人生观。现在新民主主义建设的伟大动动中,我们每个人都有责任将力量贡献出来,所以我不管我的知识怎样浅薄,应该说出来请大家批评和指导。我现在分为三段报告于后:硫化元加压法直到现在,中国广大人民应用最多的染料,还是硫化元一种。硫化元分青光、青红光和红光三种,前一种单用二硝基苯酚为主要原料,后二种是以二硝基苯酚加苦味酸为主要原料。青光红光的消费量较小,青红光的消费量最多。我在一九四二年时即做加压法的试验,证明加压熬煮所得的硫化元,其牢度(fastness)较不 I have been engaged in the dye industry for several decades. Due to my shallow ability to learn, I can not concentrate on research because of my work experience in the factory. I rarely make any contribution to the Chinese dyes, especially since political understanding is not enough to hinder my progress. After passing the three opposition and the five opposition movements, I recently took part in the study of the common program. The great Mao Tse-tung’s thought inspired me to make my thoughts fluctuate and change and established a new outlook on life. Now in the great move of new-democratic construction, each of us has a responsibility to contribute to our strength. Therefore, I do not care how superficial my knowledge should be. Please tell us for criticism and guidance. I am now divided into three sections in the future: Vulcanization Pressing Until now, the majority of Chinese people use the most dyes, or a sulfide. Sulfide yuan divided into glaucoma, red and red three kinds of light, the former with dinitrophenol as the main raw material, the latter two kinds of dinitrophenol and picric acid as the main raw material. Green light red consumption less, the most red-green consumption. I did the pressurization test in 1942 and proved that the fastness of pressurized boiled sulfur compounds was lower
