一种分散红染料的制备工艺
摘要：
本发明公开了一种分散红染料的制备工艺，包括如下步骤：S1、将C.I.分散红74染料与聚萘甲醛磺酸钠盐进行充分混合；S2、向步骤S1中的混合物中加入木质素磺酸钠后充分混合；S3、向步骤S2中的混合物中加入羧甲基纤维素钠和聚山梨酯80后充分混合；S4、向步骤S3中的混合物中加入阳离子表面活性剂后充分混合；S5、向步骤S4中经充分混合后的混合物中缓慢加入水，经砂磨混匀，制得；所述C.I.分散红74染料的重量份数为50-60份，所述C.I.分散红74染料与聚萘甲醛磺酸钠盐的重量份数比为1∶0.4-0.6；所述C.I.分散红74染料的分子结构式如(I)所示：各有效成分形成的混合网状结构与C.I.分散红74染料相互结合，并将其与织物纤维产生牢固的连接，提高其色牢度。
摘要（英）：

The invention discloses a preparation method of a dispersing red dye. The preparation method comprises S1, fully mixing a C. I. dispersing red 74 dye and sodium poly[(naphthaleneformaldehyde)sulfonate], S2, adding sodium lignosulfonate into the mixture obtained by the step S1 and carrying out full mixing, S3, adding sodium carboxymethylcellulose and polysorbate 80 into the mixture obtained by the step S2 and carrying out full mixing, S4, adding a cationic surfactant into the mixture obtained by the step S3 and carrying out full mixing, and S5, slowly adding water into the mixture obtained by the step S4 and carrying out uniform sand grinding mixing. The dispersing red dye comprises 50-60 parts by weight of the C. I. dispersing red 74 dye and a weight part ratio of the C. I. dispersing red 74 dye to the sodium poly[(naphthaleneformaldehyde)sulfonate] is 1: 0.4-0.6. The C. I. dispersing red 74 dye has a molecular structure formula shown in the description. A mixed network structure of active ingredients is combined with the C. I. dispersing red 74 dye and the composition is firmly bonded to fabric fibers so that color fastness is improved.
