Description
Technical Field
The invention belongs to the technical field of textile printing and dyeing, and particularly relates to a dyeing process of a nylon fabric.
Background
The nylon has excellent properties, such as small specific gravity, soft hand feeling, light texture, air permeability, moisture absorption, good dyeing property and the like, so that the nylon fabric has wide application range, and is generally dyed by acid dye. The wet processing fastness of the acid dye is greatly different with the dye, and the color fixing treatment is generally needed, but the fastness still can not meet the requirements when the acid dye is dyed in extra-deep colors such as scarlet, deep purple, black and the like.
In order to improve the fastness problem of dark dyeing, a novel reactive dye Eriofast can be used for dark dyeing. Zhang Gui et al adopt Eriofast reactive dye to dye in the research of nylon stretch fabric Eriofast reactive dye, can obtain dark hue on nylon stretch fabric fibre, and migration nature, compatibility are good, difficult design, the colour is stable, but often appears the cloth cover scratch problem in production.
CN103966869A discloses a dyeing process of chinlon, which comprises the following steps: (1) the method comprises the following steps of (1) gray fabric sizing, adding an anti-thermal yellowing auxiliary agent into a soaking solution, keeping the temperature of the soaking solution at 190 ℃ at 180-: 0.85-1.15, and the temperature of the dyeing liquid is kept at 40-50 ℃ for dyeing. The dyeing process of the chinlon adopts the dyeing treatment under the low temperature condition, increases the elasticity of the dyed chinlon, improves the dye uptake and reduces the occurrence of colored flowers. However, the above dyeing process is also prone to cause a problem of cloth surface scratches when dyeing a deep-dyed cloth.
Disclosure of Invention
Aiming at the defects of the prior art, the invention aims to provide a dyeing process of nylon fabric, which can avoid the problem of scratches on the cloth surface when the nylon fabric is dyed in deep color and has high dyeing color fastness.
In order to achieve the purpose, the invention adopts the following technical scheme:
a dyeing process of nylon fabric, which comprises the following steps:
1) preparing a dye solution containing a reactive dye Eriofast;
2) adding water into the water flow cylinder of the Asia rock, adjusting the pH to 4.4-4.8 by using a pH regulator, placing the chinlon fabric into the dye solution containing the step 1) prepared in the water flow cylinder of the Asia rock, adding calcium chloride, and dyeing at the temperature of 90-110 ℃; wherein the dyeing parameters are: the bath ratio is (1:11) - (1:13), the dyeing water washing is 1.1-1.3 kg, and the machine speed is 230-250 m/min.
According to the invention, when the Eriofast reactive dye is used for dyeing deep color in the water flow cylinder of the subalpine, the problem of scratching of the cloth cover during dyeing the deep color can be effectively avoided by reasonably adjusting the dyeing parameters such as bath ratio, machine condition, cloth carrying amount and the like, and the dyeing effect is good.
In the step 1), the reactive dye Eriofast comprises Eriofast yellow R, Eriofast black M and Eriofast dark blue M; the active dye Eriofast is produced by Henschel Mi company, and Eriofast yellow R, Eriofast black M and Eriofast navy M are respectively three different types of active dyes, so that the active dye has excellent compatibility, fibers can be dyed in a very similar mode in the same dyeing formula, the color and the luster are consistent, and the dyeing reproducibility and the level-dyeing property can be ensured.
Preferably, the dye liquor comprises the following components:
0.5-0.7% of Eriofast yellow R (owf), for example, the dosage of the Eriofast yellow is 0.5%, 0.6% and 0.7%;
3-5% of Eriofast black M (owf), for example, the dosage of the Eriofast black is 3%, 3.5%, 4%, 4.5%, 5%;

Comparative examples 1 to 2
The bath ratios 1:10 and 1:14 were set as comparative examples 1 and 2, respectively, and the conditions were the same as in examples 1 to 3, and the dyeing parameters and the results of the examination are shown in Table 1.
TABLE 1
As can be seen from the data in Table 1, the production was smooth and no scratches were found on the surface of the cloth in the case of examples 1, 2 and 3 having bath ratios of 1:11, 1:12 and 1: 13.
The cloth surface was scratched to different degrees when the bath ratio of comparative example 1 was 1:10 and the bath ratio of comparative example 2 was 1: 14.
Comparative example 1 bath ratio at 1:10, the buoyancy of the cloth body is insufficient due to less water, the machine is not smooth, the loop time is too long, and the cloth cover scratches are serious.
Comparative example 2 when the bath ratio is 1:14, the cloth behind the dye vat floats to the front end of the vat to press the cloth in front, so that the machine is not smooth, and the cloth surface can be scratched when the bath is too long.
Examples 4 to 6
Selecting a bath ratio of 1:12, and setting the dyeing water flushing as follows: the tests of 1.1kg, 1.2kg and 1.3kg were described as examples 4, 5 and 6, respectively, and the results of the effect of water jet on scratches are shown in Table 2.
Comparative examples 3 to 4
Selecting a bath ratio of 1:12, and setting the dyeing water flushing as follows: tests of 1.0kg and 1.4kgg were carried out as example 3 and comparative example 4, respectively, and the results of the effect of water jet on the scratches are shown in Table 2.
TABLE 2
As can be seen from the data in Table 2, the fabrics of the fabrics dyed in examples 4, 5 and 6 have no scratch when the water is flushed at 1.1kg, 1.2kg and 1.3kg, and the water is flushed at 1.2kg optimally in consideration of energy consumption in practical production.
When the water of comparative example 3 is 1.0kg and the water of comparative example 4 is 1.4kg, the cloth surface of the dyed fabric has scratches.
Examples 7 to 9
As examples 7, 8 and 9, tests were carried out while changing the machine speed (230m/min, 240m/min and 250m/min) at a bath ratio of 1:12, a water jet of 1.2kg and a single-tube load of 200kg in a water flow cylinder of subas, and the results of the effect of the machine speed on scratches were recorded as shown in Table 3.
Comparative examples 5 to 6
The results of the comparative examples 5 and 6 were obtained by changing the machine speed to 220m/min and 260m/min at a bath ratio of 1:12, a water jet of 1.2kg and a single-tube load of 200kg in the water flow cylinder of subas, and the influence of the machine speed on the scratches are shown in Table 3.
TABLE 3
As can be seen from the data in Table 3, the machine speeds of 230m/min, 240m/min and 250m/min of the examples 7, 8 and 9 have no scratches on the cloth surface, the slip is small and is between 15 and 19, so the machine speed of 240m/min is preferred.
The comparative examples 5 and 6 had scratches at the machine speeds of 220m/min and 260 m/min.
The reason why the scratch is generated at the machine speed of 260m/min of comparative example 6 may be related to the machine speed being too high, while the reason why the scratch is generated at the machine speed of 220m/min of comparative example 5 is that the machine speed is too low, the loop length is too long, especially the cloth is stretched at high temperature, the loop length is longer, and the relative slip becomes large.
Examples 10 to 11
Each cylinder has its designed cloth-carrying parameter, but in the actual production it must determine proper cloth-carrying quantity according to the specification of the dyed fabric, structure of fabric and dye combination, etc. to avoid quality problem in production, and 170g/m is selected2The nylon elastic fabric was subjected to a fabric loading test for a subazo monotube model, and the results of the effect of the fabric loading on the scratches are shown in table 4, with the fabric loading of 190kg and 200kg as examples 10 and 11.
Comparative examples 7 to 8
170g/m is selected2The nylon elastic fabric is subjected to a cloth loading test on a subalpine single-tube type, the cloth loading is 210kg, 220kg are used as comparative examples 7 and 8, and the influence result of the cloth loading on the scratch is shown in Table 4.
