Detailed Description
The terms as used herein:
"prepared from … …" is synonymous with "comprising". The terms "comprises," "comprising," "includes," "including," "has," "having," "contains," "containing," or any other variation thereof, as used herein, are intended to cover a non-exclusive inclusion. For example, a composition, process, method, article, or apparatus that comprises a list of elements is not necessarily limited to only those elements but may include other elements not expressly listed or inherent to such composition, process, method, article, or apparatus.
The conjunction "consisting of … …" excludes any unspecified elements, steps or components. If used in a claim, the phrase is intended to claim as closed, meaning that it does not contain materials other than those described, except for the conventional impurities associated therewith. When the phrase "consisting of … …" appears in a clause of the subject matter of the claims rather than immediately after the subject matter, it defines only the elements described in the clause; other elements are not excluded from the claims as a whole.
When an amount, concentration, or other value or parameter is expressed as a range, preferred range, or as a range of upper preferable values and lower preferable values, this is to be understood as specifically disclosing all ranges formed from any pair of any upper range limit or preferred value and any lower range limit or preferred value, regardless of whether ranges are separately disclosed. For example, when the range "1 ~ 5" is disclosed, the ranges described should be construed to include the ranges "1 ~ 4", "1 ~ 3", "1 ~ 2 and 4 ~ 5", "1 ~ 3 and 5", and the like. When a range of values is described herein, unless otherwise stated, the range is intended to include the endpoints thereof and all integers and fractions within the range.
In these examples, the parts and percentages are by mass unless otherwise indicated.
"part by mass" means a basic unit of measure indicating a mass ratio of a plurality of components, and 1 part may represent any unit mass, for example, 1g or 2.689 g. If we say that the part by mass of the component A is a part by mass and the part by mass of the component B is B part by mass, the ratio of the part by mass of the component A to the part by mass of the component B is a: b. alternatively, the mass of the A component is aK and the mass of the B component is bK (K is an arbitrary number, and represents a multiple factor). It is unmistakable that, unlike the parts by mass, the sum of the parts by mass of all the components is not limited to 100 parts.
"and/or" is used to indicate that one or both of the illustrated conditions may occur, e.g., a and/or B includes (a and B) and (a or B).
Embodiments of the present invention will be described in detail below with reference to specific examples, but those skilled in the art will appreciate that the following examples are only illustrative of the present invention and should not be construed as limiting the scope of the present invention. The examples, in which specific conditions are not specified, were conducted under conventional conditions or conditions recommended by the manufacturer. The reagents or instruments used are not indicated by the manufacturer, and are all conventional products available commercially.
The compounds of the invention may be conveniently prepared in a manner well known to those skilled in the art. For example, diazotizing various diazo components and nitrosyl sulfuric acid, and controlling the temperature to be 0-5 ℃; adding ice into a coupling reaction kettle, coupling the emulsifier and the corresponding coupling group at 0-5 ℃, and after reaching the end point, carrying out filter pressing and water washing to be neutral to obtain each corresponding component, wherein commercial dyes can be purchased through the market.

Wherein the dye intensity of example 1 and example is 200% and the dye intensity of comparative example 1 is 100%.
The disperse blue dyes prepared in the example 1 and the example 2 and the dye of the comparative example 1 are respectively prepared into a disperse dye suspension with the mass percentage concentration of 1% by water, 20mL of the disperse dye suspension is absorbed and mixed with 80mL of the water, the pH value of a dye bath is adjusted to 4.5-5.5 by acetic acid, then the temperature is raised to 60 ℃, 2g of polyester fiber is respectively put into the dye bath for high-temperature high-pressure dyeing, the temperature is raised to 130 ℃ within 35 minutes, the temperature is kept for 45 minutes, and the temperature is cooled to 80 ℃.
Sampling, observing a cloth sample, and measuring the sublimation fastness of the cloth sample by using GB/T5718; AATCC 61-2007 and GB/T5713 are adopted to determine the fastness to washing and water, GB/T3920 is adopted to determine the rubbing fastness, national standard and O-TEX100 standard are adopted to detect COD and environmental protection index of the residual liquid, and the determination results are shown in Table 1:
table 1 results of performance testing
Statistical analysis and calculation are carried out on the example 1 and the example 2, and the sale price of the dye is calculated to be about 75-80% of the price of the disperse blue 56 (equivalent strength), and meanwhile, the dye strength of the product is 200%, and the disperse blue 56 is 100%. The results shown in table 1 show that the COD of the dyed residual liquid of the disperse blue dye provided by the application is reduced by about 30-40%, the environmental protection index of the product is qualified, the advantage of the same depth cost performance is obvious, the sublimation fastness is good, and pad dyeing is facilitated.
Meanwhile, the measurement results of the compatibility, the lifting power and the dye uptake curve are measured by referring to GB/T2400, GB/T2397, GB/T2403 and GB/T23976 and are shown in a table 2:
TABLE 2 results of measurement of compatibility, lifting power and dye uptake curve
The results in Table 2 show that the compound type composite material has obvious composite synergistic effect.
Example 6
To better demonstrate the advantages of the disperse blue dyes provided herein, the following alternative control experiments were performed:
a common formulation for disperse green M1 is as follows:
ratio of dye name to specification
Disperse blue 56100% 4.40%
Disperse yellow 211200% 1.05%
The equivalent replacement of disperse blue 56 in the above formulation with the disperse blue dye of example 1 resulted in a new green M2 formulation as follows:
ratio of dye name to specification
Solid preparation of example 1 200% 1.1%
Disperse yellow 211200% 2.18%
Neogreen M2 was tested in the same manner as the disperse blue dye of test example 1, and the results are shown in Table 3:
TABLE 3 New Green M2 test results
As can be seen from table 3 above, the green M2 dye obtained by substituting the disperse blue dye provided in example 1 of the present application has sublimation fastness higher than that of blue 56 by more than half a grade, and has no lamp jump phenomenon (low metamerism index), and the COD of the residual liquid after dyeing is reduced by 22%, which is beneficial to the treatment of three wastes.
Example 7
The disperse blue dye provided in the embodiment 1 of the present application is used to directly replace disperse blue 2BLN 100% compound gray dye, and the compound table is shown in table 4 below:
TABLE 4 compounding table
Gray N and substituted formula gray N2 were tested using the method of testing the disperse blue dyes obtained in examples 1 and 2 and the results are shown in table 5 below:
TABLE 5 Grey N and Grey N2 test results
As shown in the above Table 5, the disperse blue dye of the invention can directly replace the conventional disperse blue 56 product, can obtain the same coloring and compounding effects, does not jump, has better rubbing fastness and sublimation fastness, similar or better performances, and has good compatibility.
