Abstract

The invention relates to a method for improving black degree of stoste dyeing viscose, and belongs to the technical field of textile. A fluorescent whitening agent solution is used for soaking black stoste dyeing viscose, and a fluorescent whitening agent comprises one or more of a fluorescent whitening agent 33, a fluorescent whitening agent DM-2622, a fluorescent whitening agent 367, a fluorescent whitening agent DMS, a fluorescent whitening agent WS, a fluorescent whitening agent KSN-1, a fluorescent whitening agent KSN-J, a fluorescent whitening agent VBL and a fluorescent whitening agentCBS-X. Regarding the problem that the black degree of the stoste dyeing viscose is not enough, by utilizing the fluorescent whitening agent, yellow light on the surface of the viscose can be eliminated, therefore the purpose of improving the black degree of the stoste dyeing viscose is achieved, and the development and utilization of the viscose industry in the stoste viscose aspect are promoted.

Description

technical field [0001] The invention relates to a method for improving the blackness of stock solution dyed viscose fiber, which belongs to the technical field of textiles. Background technique [0002] Dope dyed fiber, also known as pre-spin dyed fiber, means that the spinning dope is colored by adding masterbatch or pigment before spinning, and then spun into fiber through spinneret holes and coagulation bath spinning, so that it can be prepared Produce colored fibers without further dyeing. After the dope dyed fiber is spun and weaved, it only needs to carry out the necessary finishing to obtain the finished textile product, which avoids the complicated dyeing process, greatly reduces the emission of carbon dioxide and chemical oxygen demand, and realizes rich colors and clean production. At the same time of fusion, the discharge of sewage in the dyeing and finishing process is greatly reduced, and the cost of dyeing is reduced. Therefore, the development and research of...
