Abstract
The invention belongs to fluorescent whitening agent, and in particular to a kind of compositions of fluorescent whitening agents for pad dyeing.Said composition is uniformly formed afterwards by fluorescent whitening agent C.I.71, reactive brilliant bule KN RXN, disperse violet 2RL, glauber salt by mechanical mixture；Wherein described fluorescent whitening agent C.I.71 mass percent is 25%~75%, and reactive brilliant bule KN RXN mass percent is 0.0~1.5%, and disperse violet 2RL mass percent is 0.0~1.5%, and remaining surplus is glauber salt.The present composition improves much to the cotton whiteness after pad dyeing, and whiteness value can improve more than 10, when brightening cotton to reach identical whiteness value, the relative reduction usage amount of fluorescent whitening agent, has saved production cost.
Description
Technical field
The invention belongs to fluorescent whitening agent, and in particular to a kind of compositions of fluorescent whitening agents for pad dyeing.
Background technology
Polyester-cotton blend white goods occupies very big proportion in the product structure of state's Inner dyeings.Conventional fluorescent whitening agent should
Technique for cotton mainly has dip method and pad-dyeing method.Dip method is mainly used in cotton yarn, and cotton goods brighten；Pad-dyeing method is used for
Cotton.Dip method technological process is grown, and power consumption is big, and cost is high.Pad-dyeing method due to the time is short, continuity is good, efficiency high, with water it is few,
Discharge less, pollute the advantages that small and be used widely.Pad dyeing is applied to continuous dyeing, is generally used for the extensive of woven fabric
Dyeing process, labor productivity relatively contaminate height, and therefore, fabric is more to be dyed using knot dyeing technology.Due in high volume rolling
During dye, the usage amount of fluorescent whitening agent is larger, can increase production cost, it is therefore necessary to which studying one kind can be in pad dyeing field
The compositions of fluorescent whitening agents of cotton whiteness is improved, with cost-effective.
Patent of invention CN 1298803 discloses a kind of easily scattered powdery fluorescent whitening agent combination of industrial textile
Thing.The compositions of fluorescent whitening agents contains fluorescent dye, nonionic surfactant, anion surfactant, naphthalene sulfonic
Salt and lignosulfonates anion-proliferation agent, preservative, dust-proofing agent, inorganic salts.The powdered fluorescent composition as whitening agent can be grown
Phase stores, and has excellent dispersiveness in water, in dyeing course phenomena such as the viscous cylinder of nothing, roll banding, dyeing defect.
The A of patent of invention CN 102898870 disclose a kind of fluorescent whitening agent composition for cotton cloth, specifically by different proportion
Fluorescent whitening agent BA, disperse violet 2RL, disperse blue E-4R and glauber salt composition, the whiteness of cotton can be made by being contaminated for cotton
Value improves more than 16.
Above-mentioned two patent provides respectively a kind of to be had excellent dispersed fluorescent whitening agent and a kind of is used for cotton
The compositions of fluorescent whitening agents that cloth is contaminated.Pad dyeing involved in the present invention has no patent report with compositions of fluorescent whitening agents.
The content of the invention
The technical problems to be solved by the invention are：How to improve fluorescent whitening agent and effect is brightened to cotton in pad dyeing
Rate.
The technical solution adopted in the present invention is：A kind of compositions of fluorescent whitening agents for pad dyeing, said composition is by glimmering
Optical brightener C.I.71, Reactive Brilliant Blue KN-R XN, disperse violet 2RL, glauber salt are uniformly formed afterwards by mechanical mixture；It is wherein described
Fluorescent whitening agent C.I.71 mass percent be 25%~75%, Reactive Brilliant Blue KN-R XN mass percent for 0.0~
1.5%, disperse violet 2RL mass percent are 0.0~1.5%, and remaining surplus is glauber salt.
Preferably, said composition passes through machinery by said composition by fluorescent whitening agent C.I.71, disperse violet 2RL, glauber salt
Formed after well mixed；Wherein described fluorescent whitening agent C.I.71 mass percent is 25%~75%, disperse violet 2RL
(200%) mass percent is 0.0~1.5%, and remaining surplus is glauber salt.
Preferably, said composition by said composition by fluorescent whitening agent C.I.71, glauber salt by mechanical mixture it is uniform after
Formed；Wherein described fluorescent whitening agent C.I.71 mass percent is 25%~75%, and remaining surplus is glauber salt.
Preferably, described Reactive Brilliant Blue KN-R XN intensity is 100%.
Preferably, disperse violet 2RL intensity is 200%.
The beneficial effects of the invention are as follows：The present composition improves much to the cotton whiteness after pad dyeing, and whiteness value can
More than 10 are improved, when brightening cotton to reach identical whiteness value, the relative reduction usage amount of fluorescent whitening agent, is saved
Production cost.
