(application example 1)
The application example is that the dyeing device of the embodiment 1 is adopted to dye the denim warp, and the specific method is as follows:
firstly, stirring and mixing dye liquor and nitrogen in a gas-liquid mixing device according to the volume ratio of 1: 10 to form a gas-liquid mixture, then pressing the gas-liquid mixture into the dyeing device from a feed inlet 1-1 at a certain pressure, and coating the mixture on the denim warp yarns through coating gaps.
The dye liquor of this example consisted of: 30g/L (equivalent to 3%) of surfactant, 5g/L (equivalent to 0.5%) of penetrant, 150g/L (equivalent to 15%) of pre-reduced indigo dye, and the balance of water.
The surfactant used in this example was A0S14-16 [ i.e., sodium C14-16 alkenyl sulfonate ], and the penetrant was SAS 60. The coating gap of this example is 40mm and the yarn coverage factor of the denim warp is 75%.
And secondly, performing delayed oxidation on the denim warp yarns coated with the gas-liquid mixture in the step I for 125 seconds in an oxygen-free environment.
And thirdly, oxidizing and fixing the denim warp yarns subjected to the delayed oxidation in an aerobic environment, and finally drying and sizing.
(test examples)
The yarn cover factor is a parameter representing the size of the space between yarns.
In the case of the same yarn size, the larger the number of yarn ends, the larger the yarn covering factor, indicating the tighter the yarn arrangement.
In the case of different yarn specifications, the yarn ends are the same, the thicker the yarn is, the larger the yarn covering coefficient is, and the more densely the yarn is arranged.
(test 1-1 to test 1-7)
The yarn coverage coefficient of each test example is 75%, wherein the test examples 1 to 5 are application examples 1, and the other test examples are different from the test examples 1 to 5 only in coating gaps, and the coating effect of each test example is observed, and the results are shown in table 1.
TABLE 1
| Coating gap | Coating pressure | Uniformity of coating | |
| Test examples 1-1 | 5mm | 4.2kPa | Is slightly uneven |
| Test examples 1 to 2 | 10mm | 3.8kPa | Uniformity |
| Test examples 1 to 3 | 20mm | 3.2kPa | Uniformity |
| Test examples 1 to 4 | 30mm | 2.2kPa | Uniformity |
| Test examples 1 to 5 | 40mm | 1.4kPa | Uniformity |
| Test examples 1 to 6 | 45mm | 1.1kPa | Is slightly uneven |
| Test examples 1 to 7 | 50mm | 0.6kPa | Unevenness of |
As can be seen from table 1:
when the coating gap is less than 10mm, the coating pressure is high, the output quantity of the gas-liquid mixture is low, the contact time of the denim yarn and the gas-liquid mixture is short, the gas-liquid mixture penetrates through the inner side of the yarn, the surface layer is coated less, and the coating uniformity is poor. The coating gap is 10-40 mm, the coating pressure is reduced, the output quantity of the gas-liquid mixture is increased, the contact time of the jean yarns and the gas-liquid mixture is prolonged, and the coating uniformity is good. When the coating gap is higher than 40mm, the coating pressure is too low, the contact time of the jean yarn and the gas-liquid mixture is too long, and the coating is also uneven.
In addition, the core penetration degree is reduced along with the increase of the coating gaps, which means that the poorer the core penetration of the denim warp yarn is, the better the white core effect is, and the better the old imitation effect of the denim garment is.
(test example 2-1 to test example 2-7)
The yarn coverage factor for each test example was 90%, the same difference was that for the coating gap, the other conditions were the same as for example 1, and the results are shown in Table 2.
TABLE 2
| Coating gap | Coating pressure | Uniformity of coating | |
| Test example 2-1 | 5mm | 4.5kPa | Is slightly uneven |
| Test examples 2 to 2 | 10mm | 4.0kPa | Uniformity |
| Test examples 2 to 3 | 20mm | 3.3kPa | Uniformity |
| Test examples 2 to 4 | 30mm | 2.5kPa | Uniformity |
| Test examples 2 to 5 | 40mm | 1.5kPa | Is slightly uneven |
| Test examples 2 to 6 | 45mm | 1.3kPa | Unevenness of |
| Test examples 2 to 7 | 50mm | 0.8kPa | Unevenness of |
As can be seen from table 2: when the yarn coverage coefficient is 90%, the coating gap with good coating uniformity is 10-30 mm.
(test example 3-1 to test example 3-7)
The yarn coverage factor for each test example was 60%, the same difference was that for the coating gap, the other conditions were the same as in example 1, and the results are shown in Table 3.
TABLE 3
| Coating gap | Coating pressure | Uniformity of coating | |
| Test examples3-1 | 5mm | 3.9kPa | Unevenness of |
| Test examples 3 and 2 | 10mm | 3.5kPa | Is slightly uneven |
| Test examples 3 to 3 | 20mm | 3.1kPa | Uniformity |
| Test examples 3 to 4 | 30mm | 2.3kPa | Uniformity |
| Test examples 3 to 5 | 40mm | 1.5kPa | Uniformity |
| Test examples 3 to 6 | 45mm | 1.0kPa | Uniformity |
| Test examples 3 to 7 | 50mm | 0.5kPa | Is slightly uneven |
As can be seen from table 3: when the yarn coverage coefficient is 60%, the coating gap with good coating uniformity is 20-45 mm.
In addition, it can be seen from the respective test examples that:
the optimal dyeing effect can be achieved only when the coating gap is correspondingly reduced along with the increase of the yarn covering coefficient. This is because the yarn covering factor is increased, which means that the yarn is closely arranged, so that the resistance of the gas-liquid mixture to penetrate through the yarn is increased, and the coating gap is decreased, so that the coating pressure can be increased to offset the increased resistance, thereby ensuring good level-dyeing property.
The numerical range of the coating pressure with better coating uniformity is relatively higher along with the increase of the yarn coverage coefficient. For example, the coating pressure value range with good coating uniformity of the yarn coverage coefficient of 60% is 1.0-3.1 kPa; the numerical range of the coating pressure with good coating uniformity and a yarn coverage coefficient of 75% is increased to 1.4-3.8 kPa; the coating pressure value range with better coating uniformity and 90% of yarn coverage coefficient is increased to 2.5-4.0 kPa. This is also because the higher the yarn coverage, which means that the yarn is tightly packed, the greater the resistance of the gas-liquid mixture to penetrate the yarn, the higher the pressure which naturally ensures a better coating uniformity.
Therefore, the coating pressure is changed by adjusting the coating gap, so that the optimal dyeing effect can be achieved by different yarn coverage coefficients.
