| 15 | 9.4756 |
| 20 | 10.3314 |
As can be seen from table 3: as the amount of the dye is increased, the K/S value is increased, and the color yield is increased. The specific dosage is determined according to the required color depth during dyeing, and the required dye dosage is small during dyeing light color; when the dye is used for dyeing dark colors, the required dye dosage is large.
Example 6:
effect of pH on dyeing Properties
A short-process dyeing method for polyester-cotton blended fabric comprises the following steps:
the dyeing process comprises the following steps:
(1) The process prescription is as follows: the dye dosage is 10g/L, the solvent dosage is 10g/L, and the pH is =3 → 9.
(2) The process conditions are as follows: two-dipping and two-rolling (the liquid carrying rate is 80%) → drying (the temperature is 100 ℃, the time is 10 minutes) → baking (the temperature is 180 ℃, the baking time is 5 minutes) → reduction cleaning → water washing → drying.
The pH was adjusted using the above process and its effect on staining performance was tested as shown in table 4.
TABLE 4 influence of the dye pH on the dyeing Properties
| pH | K/S |
| 3 | 7.1242 |
| 5 | 7.3881 |
| 7 | 7.2152 |
| 9 | 6.0116 |
As can be seen from table 4: 4, the change of K/S value is large when the pH values are different, and the color yield is large when the dyeing pH value is under an acidic condition; under alkaline conditions, the color yield is reduced, and the color light is changed.
Example 7:
effect of different baking temperatures on dyeing Properties
A short-process dyeing method for polyester-cotton blended fabric comprises the following steps:
the dyeing process comprises the following steps:
(1) The process prescription is as follows: the dye dosage is 10g/L, the solvent dosage is 10g/L, and the pH =3 → 9.
(2) The process conditions are as follows: two-dipping and two-rolling (the liquid carrying rate is 80%) → drying (the temperature is 100 ℃, the time is 10 minutes) → baking (the temperature is 170 → 210 ℃, the baking time is 5 minutes) → reduction cleaning → water washing → drying.
The influence of the baking temperature on the dyeing performance was tested by using the above process, as shown in table 5.
TABLE 5 Effect of different baking temperatures on dyeing Properties
| Baking temperature (. Degree.C.) | K/S |
| 170 | 6.7051 |
| 180 | 7.3881 |
| 190 | 7.6242 |
| 200 | 7.1319 |
| 210 | 6.8754 |
As can be seen from table 5: and (3) with the increase of the baking temperature, the K/S value is further increased, when the K/S value is maximum under the dyeing condition of 190 ℃, the temperature is continuously increased, and the color yield is slightly reduced.
Example 8:
a short-process dyeing method for polyester-cotton blended fabric comprises the following steps:
the dyeing process comprises the following steps:
(1) The process prescription is as follows: the dye dosage is 10g/L, the solvent dosage is 10g/L, and the pH is =3 → 9.
(2) The process conditions are as follows: two-dipping and two-rolling (the liquid carrying rate is 80%) → baking (the temperature is 100 ℃, the time is 10 minutes) → baking (the temperature is 190 ℃, the baking time is 1 → 5 minutes) → reduction cleaning → water washing → baking.
The above process was used to test the effect on dyeing performance by varying the baking time, as shown in table 6.
TABLE 6 Effect of baking time on dyeing Properties
| Baking temperature (min) | K/S |
| 2 | 4.3681 |
| 3 | 6.8242 |
| 4 | 7.2311 |
| 5 | 7.6242 |
| 6 | 7.5146 |
Example 9:
color fastness
A short-process dyeing method for polyester-cotton blended fabric comprises the following steps:
the dyeing process comprises the following steps:
the process prescription is as follows: the dye dosage is 10g/L, the polyvinylpyrrolidone dosage is 10g/L, and the pH is =5.
The process conditions are as follows: two-dipping and two-rolling (the liquid carrying rate is 80%) → drying (the temperature is 100 ℃, the time is 10 minutes) → baking (the temperature is 190 ℃, the baking time is 5 minutes) → reduction cleaning → water washing → drying. The samples of the above examples were tested for fastness to dyeing and the results are shown in Table 7.
TABLE 7 color fastness
As seen from Table 7, the dyed sample was excellent in the color fastness, the soaping fastness was class 4 → 5, and the rubbing fastness was class 5.
And (3) analysis and summary:
in combination with the contents described in example 1 → 9, it can be found that:
1. the invention adopts a C.I. disperse blue 32 dye to dye polyester and cotton of the polyester-cotton blended fabric, simplifies the traditional disperse/active two-bath dyeing process of the polyester-cotton blended fabric into the process of 'dipping disperse dye solution → heating → cooling, reduction cleaning, washing → dipping active dye solution → heating, alkali adding and color fixing → cooling, soaping, washing → drying → shaping → finished product' to the process of 'dipping and rolling disperse dye solution → drying → baking → reduction cleaning → washing → drying → shaping → finished product', shortens the dyeing process flow and realizes the technical breakthrough of no saline and alkaline consumption in the traditional dyeing process of the polyester-cotton blended fabric.
2. By controlling the processes of the solvent type, the solvent dosage, the dyeing pH, the baking temperature, the baking time and the like, the apparent color yield of the fabric can be effectively improved, and finally the short-process dyeing of the cotton-polyester blended fabric is realized.
3. The comprehensive optimal embodiment is as follows:
(1) The process formula comprises the following steps: the dye dosage is 10g/L, the polyvinylpyrrolidone dosage is 10g/L, and the pH =5.
(2) The process conditions are as follows: double dipping and double rolling (the liquid carrying rate is 80%) → drying (the temperature is 100 ℃, the time is 10 minutes) → baking (the temperature is 190 ℃, the baking time is 5 minutes) → reduction cleaning → water washing → drying → shaping.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered as the technical solutions and the inventive concepts of the present invention within the technical scope of the present invention.
