Abstract

The invention discloses a dark blue disperse dye which comprises, by weight, 7-9% of component A, 3-4.5% of component B, 40-43% of component C, 29-33% of component D, and 14-20% of component E, the weight percentages of the components are 100% in total. As the components of the dark blue disperse dye are not easy to pollute fibers, a process of reduction washing for pure polyester is omitted when the dark blue disperse dye is applied to dyeing of polyester and spandex blended textile, and color fastness requirements can be met by one alkali reduction on the polyester and spandex blended textile, at least one barrel of water can be saved, emission of waste water is reduced, and the purpose of environmental protection can be achieved.

Description

A kind of DISPERSE NAVY BLUE EXSF 300﹠ BLUE 56 100 look dyestuff and application thereof

Technical field

The present invention relates to the disperse dye composition preparation field, relate in particular to a kind of a kind of DISPERSE NAVY BLUE EXSF 300﹠ BLUE 56 100 look dyestuff and application thereof that is applicable to terylene and spandex blended fabric dyeing.

Background technology

In recent years; every laws and regulations of environmental protection aspect have all been put into effect in every country and area in succession; China has also determined to economize on resources and the fundamental state policy of protection of the environment; large to energy consumption; the dyeing and finishing industry that blowdown is large is had higher requirement; traditional high fastness dispersed dye are applied to pure dyeing terylene and must wash through reduction at least one times, and application terylene and spandex blended fabric need twice reduction to wash just at least can reach the fastness requirement.

Common DISPERSE NAVY BLUE EXSF 300﹠ BLUE 56 100 in the market mainly contains DISPERSE NAVY BLUE EXSF 300﹠ BLUE 56 100 79, DISPERSE NAVY BLUE EXSF 300﹠ BLUE 56 100 291 etc., this type of conventional dyestuff is because Stability Analysis of Structures, easy cleaning not, cause dyefastness relatively poor, must rely on repeatedly reduction to wash fastness is increased that (the reduction mode of washing has two kinds of 1. alkali cleanings: powder and sheet alkali take a policy; 2. pickling: add acidic reduction detergent and acetic acid), reach better fastness such as need, the application terylene needs once to reduce at least to be washed; Spandex blended fabric needs twice reduction to wash at least, and this has just prolonged dyeing time, has improved cost, has increased the dyeing waste-water quantity discharged.

Summary of the invention

Technical problem to be solved by this invention is: provide a kind of dyeing behavior good, be difficult for to break away from polyster fibre after the dyeing, dye mixture is reached exempt to reduce and wash or reduce the DISPERSE NAVY BLUE EXSF 300﹠ BLUE 56 100 look dyestuff that number of times is washed in reduction.

For solving the problems of the technologies described above, the technical solution used in the present invention: a kind of DISPERSE NAVY BLUE EXSF 300﹠ BLUE 56 100 look dyestuff, it consists of by mass percentage: component A:7-9%, B component: 3-4.5%, component C:40-43%, component D:29-33%, component E:14-20%, said components mass percent sum is absolutely;

Described component A, (I) is as follows for its structural formula:

Described B component, (II) is as follows for its structural formula::

Described component C, (III) is as follows for its structural formula:

Described component D, (IV) is as follows for its structural formula:

Described component E is methylene-bis bitter edible plant sodium sulfonate (trade(brand)name: dispersion agent NNO, molecular formula: CH ₂(C ₁₀H ₆SO ₃Na) ₂Or C ₂₁H ₁₄O ₆S ₂Na ₂, molecular weight: 472.44, CAS number: 36290-04-7).

Described DISPERSE NAVY BLUE EXSF 300﹠ BLUE 56 100 look dyestuff, its preferred group becomes by mass percentage: component A:8%, B component: 4%, component C:42%, component D:30%, component E:16%.

Described DISPERSE NAVY BLUE EXSF 300﹠ BLUE 56 100 look dyestuff, its preparation method: by above-mentioned mass percent, each component fully ground stir, obtain DISPERSE NAVY BLUE EXSF 300﹠ BLUE 56 100 look dyestuff.

The present invention also provides a kind of DISPERSE NAVY BLUE EXSF 300﹠ BLUE 56 100 look dyestuff as the application in terylene and the spandex blended fabric dye.

Owing to having adopted technique scheme, the present invention has following advantage and effect: DISPERSE NAVY BLUE EXSF 300﹠ BLUE 56 100 dye composition provided by the invention, because its component of selecting all is the product that is difficult for polluting fiber, so it is applied to terylene and spandex blended fabric dyeing, need not reduction at pure terylene washes, only need the primary alkali reduction to wash on terylene and the spandex blended fabric and can reach the fastness requirement, at least can save a cylinder water, reduce discharge of wastewater, shorten staining procedure, reduce dyeing time, reduce production costs, industrial application value is high.

Embodiment

Be described in further detail in conjunction with specific embodiments, make advantage of the present invention more obvious.Should be appreciated that, content wherein is just with explaining, and absolutely not protection scope of the present invention is construed as limiting.The experimental technique of unreceipted actual conditions in the following example usually according to normal condition, or carries out according to the condition that manufacturer advises.Unless otherwise indicated, otherwise all umbers are weight part, and all per-cent is mass percent.
