Description

Technical Field

[0001] The present application relates to the field of disperse dyes, and in particular to a high-fastness disperse dye composition, a high-fastness disperse dye product and uses thereof. Background Art

[0002] With the development of the textile industry, more and more new functional materials and designs are being used in the production of textile clothing and fabrics, such as the development of functional polyester fabrics, the application of polyester-spandex stretch fabrics and new polyester fiber fabrics, and the contrasting color matching design of clothing and fabrics. These clothing and fabrics have higher requirements for the washing fastness of disperse dyes. At present, the commonly used monoazo and anthraquinone disperse dyes can no longer meet the market's requirements for high washing fastness of fabrics. In order to improve the washing fastness of polyester-spandex stretch fabrics, fine denier polyester fabrics and polyester contrasting color clothing, it is necessary to develop disperse dyes with high washing fastness, which has also become a research hotspot in the printing and dyeing industry.

[0003] In terms of fastness, blister fastness, washing fastness and white fastness are three more important indicators. At present, there is a lack of dyes with outstanding advantages in blister fastness, washing fastness and white fastness and good lifting power on the market, especially for polyester-spandex fabrics. Because the surface of spandex fiber has a large adsorption effect on disperse dyes, it is easy to fall off after washing after dyeing and then stain other fibers, resulting in poor fastness to washing and soaking, so the selection of disperse dyes is particularly important. In recent years, the development of a dye composition and its products with good lifting power, outstanding blister fastness, washing fastness and white fastness, suitable for wide use in polyester-spandex fabrics, has gradually become one of the research focuses.

It should be understood that the following drawings only show certain embodiments of the present application and therefore should not be regarded as limiting the scope of the present application.

[0064] As used herein:

[0065] "Prepared from" is synonymous with "comprising." As used herein, the terms "comprising," "including," "having," "containing," or any other variation thereof, are intended to cover a non-exclusive inclusion. For example, a composition, process, method, article, or apparatus that comprises the listed 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.

[0066] The conjunction "consisting of excludes any unspecified element, step, or component. If used in a claim, this phrase renders the claim closed-ended so that it does not include materials other than those described, except for conventional impurities associated therewith. When the phrase "consisting of" appears in a clause of the body of a claim rather than immediately following the subject matter, it limits only the elements described in that clause; other elements are not excluded from the claim as a whole.

[0067] When an amount, concentration, or other value or parameter is expressed as a range, a preferred range, or a range defined by a series of upper preferred values ​​and lower preferred values, this should be understood as specifically disclosing all ranges formed by any pairing of any range upper limit or preferred value with any range lower limit or preferred value, regardless of whether the range is disclosed separately. For example, when a range of "1 to 5" is disclosed, the described range should be interpreted as including ranges "1 to 4", "1 to 3", "1 to 2", "1 to 2 and 4 to 5", "1 to 3 and 5", etc. When a numerical range is described in this article, unless otherwise stated, the range is intended to include its end values ​​and all integers and fractions within the range.

[0068] In these examples, parts and percentages are by mass unless otherwise indicated.

[0069] "Parts by mass" refers to the basic unit of measurement for expressing the mass ratio of multiple components. 1 part can represent any unit mass, such as 1g or 2.689g. If we say that the mass of component A is a parts and the mass of component B is b parts, it means the ratio of the mass of component A to the mass of component B is a:b. Alternatively, it means that the mass of component A is aK and the mass of component B is bK (K is an arbitrary number, indicating a multiple factor). It should not be misunderstood that, unlike the mass parts, the sum of the mass of all components is not limited to 100 parts.

[0070] "And / or" is used to indicate that one or both of the stated situations may occur, for example, A and / or B includes (A and B) and (A or B).

[0071] The embodiments of the present application will be described in detail below in conjunction with specific examples, but it will be appreciated by those skilled in the art that the following examples are only used to illustrate the present application and should not be considered as limiting the scope of the present application.

[0125] Weigh 2 grams of disperse dye products prepared in Examples 1 to 15 and Comparative Examples 1 to 4, respectively, and treat polyester-ammonia knitted fabrics (90 / 10) by conventional high temperature and high pressure dyeing method. During the treatment process, the dyeing depth is controlled to be 4.0% owf, the bath ratio is 1:20, the pH value of the dye bath is 4.0±0.2, and the dyeing is carried out at room temperature. The temperature is raised to 130°C at 1°C / min, and the temperature is kept for 45 minutes. The dyed fabric is washed, reduced, cleaned, neutralized, and fixed (180°C×30s) according to the usual method to obtain a dyed fabric. Then, the washing fastness, white fastness, and water fastness are tested, wherein the washing fastness is tested with reference to the AATCC61 2A standard. The white fastness and water fastness test methods are as follows:

[0126] White fastness:

[0127] Sew 1g of polyester-spandex knitted fabric and 1g of white cloth of the same specification together, then soak them in a 60℃ aqueous solution (4g / L Tide laundry detergent) for 30min with a bath ratio of 1:50. Determine the color of the residual liquid and grade the staining of the white cloth.

[0128] Water fastness:

[0129] Soak 1g of polyester / ammonia knitted fabric in a 100℃ aqueous solution (5g / L Tide laundry detergent) for 5 minutes with a bath ratio of 1:100, and judge the color of the residual liquid.

[0132]

[0133]

[0134] From the test results in Table 2, combined with the structural characteristics of the dye components in Example 1 and Comparative Example 1, it can be seen that the component of formula (A) in Comparative Example 1 is green light disperse blue, and due to its different structure, its alkali water solubility is poor, and thus the floating color removal rate is slightly poor. Therefore, the disperse dye composition provided by the present invention has more superior fastness properties when dyeing polyester-spandex fabrics.
