Table: experimental data analysis table for the cloth samples of examples 1 to 11 each carried out at a bath ratio of 1:10
Figure BDA0003582367800000121
Color difference value: the difference of colors is expressed by delta E, and the color difference is generally evaluated and widely applied to plastics, printing, paint ink, textile clothing and the like (delta E <0.25, color difference is very small or none, 0.25< delta E <0.5, color difference is tiny, 0.5< delta E <1.0, color difference is tiny to medium, is accepted only in some application fields, 1.0< delta E <2.0, color difference is medium, is accepted only in specific applications, and 2.0< delta E <4.0 delta E is larger).
The surface depth of the dyed object is an important index for comprehensively evaluating the dyeing performance of textiles, such as hue, brightness, saturation, uniformity and the like of the color. Many dyes tend to have a degree of impact on hue, brightness, and saturation of the dye as the depth of dyeing increases or decreases.
Examples 12 to 13 were the same as example 4 except that the dyeing depths of cotton and rayon were different from each other.
From the data of example 1 and example 2 in the table, it can be seen that the change of dye liquor concentration does not cause color difference to cotton and man cotton subjected to the same-bath dyeing treatment when the reactive navy dye is used for the same-bath dyeing of cotton and man cotton.
As can be seen from the control groups 1-6, when the dye A and the dye B respectively dye cotton and human cotton or interweaved fabrics blended by the cotton and the human cotton in one bath, the dyed cotton and the human cotton have the problem of larger chromatic aberration; as can be seen from the control group 1, the control group 3, the control group 2 and the control group 4, the problem that the dye A and the dye B have larger chromatic aberration between the dyed cotton and the human cotton when the cotton and the human cotton or the cotton and the human cotton blended interweaved fabrics are dyed in the same bath can not be solved by adjusting the concentration of the dye.
It can be seen from the control groups 1-2 and example 1, the control groups 3-4 and example 2, and the control groups 7-8 and example 8 that the problem of a large color difference between dyed cotton and human cotton when the dye a and the dye B are respectively dyed in one bath on cotton and human cotton or cotton and human cotton blended interwoven fabrics can be improved only when the dye a and the dye B are mixed.
From the data of example 2 and example 3 in the table, it can be obtained by analysis that when the reactive navy dye performs one-bath dyeing on cotton and human cotton, the reactive navy dye is less affected by the dyeing accelerator and the addition amount of the color fixing agent, so that it can be presumed that the reactive navy dye can perform good dyeing on cotton and human cotton.
From the data of example 3 and example 4 in the table, it can be analyzed that when the reactive navy dye performs one-bath dyeing on cotton and human cotton, the reactive navy dye is less affected by the dyeing depth, so that the cotton and human cotton can reach the balance of the two fiber depths at each depth.
From the data of the examples 5 and 6 in the table, it can be analyzed that the reactive navy blue dye can dye cotton and human cotton with different mixing ratios in the same bath, the color difference between the dyed cotton and the human cotton is smaller, the saturation and the fullness of the cloth cover are high, and the cloth cover effect is good.
According to the embodiment 12-13, when the reactive navy blue dye is used for carrying out one-bath dyeing on cotton or human cotton, the cotton and the human cotton are in different dyeing depths, and small chromatic aberration exists between the dyed cotton and the human cotton, so that it can be presumed that the reactive navy blue dye is used for carrying out one-bath dyeing on the cotton and the human cotton or the interwoven fabric blended by the cotton and the human cotton, the cotton and the human cotton are in different dyeing depths, and the reactive navy blue dye can reach the balance of the cotton and the human cotton fiber depths.
From examples 6-11, it can be seen that the reactive navy blue dye compounded by 60-90wt% of dye A and 10-40wt% of dye B and the balance of auxiliary agent C has very small chromatic aberration when the cotton and the rayon or the cotton and the rayon blended interwoven fabric are subjected to one-bath dyeing.
