Embodiment 1

[0010] The weight percent of the present invention is: C.I. disperse orange 73 6%, C.I. disperse orange 61 6%, C.I. disperse violet 77 5%, C.I. disperse violet 336%, C.I. disperse blue 291 9%, C.I. , dustproof oil 1.7%, dispersing complexing agent 0.3%.

Embodiment 2

[0012] The weight percent of the present invention is: C.I. disperse orange 73 7%, C.I. disperse orange 61 7%, C.I. disperse violet 77 6%, C.I. disperse violet 33 7%, C.I. disperse blue 291 10%, C.I. 51%, dustproof oil 1.7%, dispersing complexing agent 0.3%.

[0013] The raw materials that the present invention adopts can all be bought on the market.

[0014] Color Index is the meaning of "dye index number", which is an international common dye name.

[0015] The anti-dust oil is white fire oil, which is used to prevent dust from flying when the dye is transported.

[0016] The dispersant is lignin sulfonate, which acts to prevent the disperse dyes from agglomerating and precipitating in water.

[0017] The dispersing and complexing agent is ethylenediaminetetraacetic acid, which acts to reduce water hardness.

[0018] Dustproof oil, dispersant and dispersing complexing agent are common additives of disperse dyes, not as the main content of the present invention.

Abstract

The invention relates to a dispersed black dye for memorability fiber, which is composed of the following ingredients by weight percentage: 5-15 percent of Color Index C.I. disperse orange 73, 5-20 percent of C.I. disperse orange 61, 4-10 percent of C.I. disperse violet 77,5-15 percent of C.I. disperse violet 33, 8-15 percent of C.I. disperse blue 291, 6-15 percent of C.I. disperse blue 165, 50-59 percent of dispersing agent, 1-2 percent of dust laying oil and 0.2-0.3 percent of disperse complexing agent; the dispersed black dye has the beneficial effects that: the memorability fiber can be dyed at low temperature, so as not to reduce the fiber shape holding facility and achieve the dying firmness of conventional high-temperature disperse dye.

Description

technical field [0001] The invention relates to a black dye, in particular to a disperse black dye (disperse black PTT) for memory fibers. Background technique [0002] Memory fiber is a special kind of polyester fiber. The fabric woven by it has the ability to maintain physical shape, so it is called memory fiber. In the prior art, high-temperature disperse dyes need to be dyed at 130-135°C, but at this temperature, the shape retention ability of the fibers will be reduced; while in the prior art, low-temperature disperse dyes are easy to dye memory fibers and have poor color fastness. The market urgently needs products with high color fastness and dyeing at lower temperature. Contents of the invention [0003] The technical problem to be solved in the present invention is to provide a disperse black dye for memory fibers, aiming to solve the above problems. [0004] In order to solve the above technical problems, the present invention is achieved through the following ...
