Technical Field
The invention relates to the technical field of fabric dyeing and finishing, in particular to a method for dyeing a nylon-cotton blended fabric.
Background
Chinlon is the trade name for polyamide fiber. The nylon has a series of excellent characteristics, such as good wear resistance and elasticity, high strength and extensibility, small specific gravity, mildew resistance, moth resistance and the like. The nylon has a longitudinal smooth morphological structure, a round cross section, a macromolecular main chain formed by carbon atoms and nitrogen atoms with the same rule, and no side groups on the main chain, so that the nylon is easy to form crystals. Among all natural fibers and chemical fibers, the nylon has the highest resilience, a large number of methylene-CH-groups are arranged in a nylon macromolecule structure, the nylon macromolecules are easily in an irregular curling state in a loose state, the length of a stretched molecular chain is obviously increased when the nylon is stretched by an external force, and after the external force is cancelled, the stretched molecular chain is converted into a curling state again due to the action of a hydrogen bond to show high extensibility and good resilience.
When the cotton-nylon fabric is dyed in a light color system, a product with uniform cloth cover and stable quality can be obtained by adopting an acidic and active two-bath experiment. However, when the cloth cover is dyed in a deep color system, the dyeing is carried out by adopting acid and active two-bath pad dyeing, and the problems of nylon color difference, insufficient cloth cover depth and the like exist; in order to improve the staining of nylon, the conventional method is that after the acid dyeing is finished, sodium hydroxide or sodium hydrosulfite is used for reduction cleaning, and after the floating color is washed away, the activity is carried out; in the method, when caustic soda or sodium hydrosulfite is used for reduction cleaning, the color loss is serious, the depth of a cloth cover is influenced, and the problem of nylon color difference exists.
Disclosure of Invention
Aiming at the problems of color difference, low fastness and the like of brocade and cotton fabric dyeing in the prior art, the invention provides the dyeing method of the brocade and cotton fabric blended fabric, which can realize deep color system dyeing of the brocade and cotton fabric blended fabric, obtain a dyed product with high color fastness and avoid the phenomenon of mutual contradiction between the depth and the fastness when the brocade and cotton fabric is dyed in the deep color system.
The invention provides a dyeing method of a nylon-cotton blended fabric, which comprises the following steps of padding the nylon-cotton blended fabric with an acid dye, steaming for the first time, washing for the first time, soaping for the first time, ironing dry for the first time, padding with a reactive dye, steaming for the second time, washing for the second time, soaping for the second time, ironing dry for the second time, and finishing; wherein, an anionic color fixing agent is added into the soaping agent during the first soaping; the finishing agent is a cationic color fixing agent during after finishing.
Further, an air pressure air film type horizontal strong padding machine is adopted to pad the acid dye, the acid dye consumption is 60-100 g/L, and the padding residual rate is 50-70%.
Further, before one-time steaming, the fabric needs to be padded with acidic vapor-liquid, wherein the acidic vapor-liquid is an acidic solution with the pH value of 5-6.
Further, a continuous pressure-suction steaming and dyeing color testing machine is adopted for steaming for one time, the steaming temperature is 100-102 ℃, and the steaming time is 70-90 s.
Furthermore, during one-time soaping, the dosage of the soaping agent is 1-4 g/L, and the dosage of the anionic color fixing agent is 1-3 g/L.
Further, an air pressure air film type horizontal strong padding machine is adopted to pad the reactive dye, the consumption of the reactive dye is 40-90 g/L, and the padding allowance is 50-70%.
Further, secondary steaming is carried out by adopting a continuous pressure-suction steaming and dyeing color testing machine, and the steaming temperature is 100-102 ℃.
Furthermore, the dosage of the secondary soaping agent is 1-4 g/L.
Further, the after-finishing method is that an air pressure air film type horizontal heavy padding machine is adopted to pad the finishing liquid, and the dosage of the finishing agent cation color fixing agent in the finishing liquid is 10-20 g/L.
The principle of the invention is that the invention utilizes the theory of forming a film by an acid color fixing agent, after padding acid dyes, an anionic acid color fixing agent is adopted as a macromolecular compound, a plurality of sulfonate groups are contained in the anionic acid color fixing agent to be combined with the terminal amino bonds of the nylon fibers to form a net-shaped structure which can coat and attach dyes, the acid dyes are firstly fixed, and the washing fastness is improved; and then dyeing cotton by using reactive dye, and after dyeing, performing after-treatment, namely fixing by using the cationic fixing agent, so as to play a role in further enhancing the fixation of the acid dye. The dyeing method of the invention is defined as a 'yin-yang double-solid' dyeing process based on the theory.
The dyeing method has the beneficial effects that the dyeing method provided by the invention has deep dyeing and high color fastness on the chinlon blended fabric, and compared with the existing deep-color process, the dyeing method can obviously reduce the dye consumption, shorten the process flow, reduce the cost, save energy and reduce emission.

And testing the left, middle and right K/S values of the fabric by adopting a Datecolor color measurement system, selecting the K/S value at the middle position of the cloth sample as a reference, and determining whether the fabric has the problem of left, middle and right color difference by comparing the K/S values at the left, middle and right positions of the fabric.
(3) Soaping fastness testing method
The test was carried out according to the textile soaping fastness standard AATCC 61-2A. The method simulates manual, household or commercial washing modes, washes dyed fabrics for a certain time under the conditions of specified temperature, detergent, bleaching, friction and the like, observes the color change of a sample, and evaluates the change of the sample and the staining grade of the attached lining fabric by using a gray sample card.
(4) Friction fastness testing method
The test was carried out according to the crockfastness standard AATCC 8. The color transfer to the white rubbing cloth can be determined by comparing with a stained gray card or 9-grade colored stained gray to determine the dry and wet rubbing fastness grade.
The data of the colorfastness tests of the examples and comparative examples are shown in Table 1. The results of the test for the depth of dyeing of the examples and comparative examples are shown in Table 2, where the depth of dyeing (K/S) is based on the comparative example in which no reductive cleaning was carried out in the corresponding dyeing process, in Table 2.
TABLE 1 data of the colorfastness tests of the examples and comparative examples
Table 2 example and comparative example stain depth test data
As can be seen from tables 1 and 2, the invention not only can improve the cloth cover color yield (the deep blue color yield is about 3-4% deeper than that of unreduced cleaning, and the black color is about 2% shallower than that of unreduced cleaning (about 4% deeper than that of reduced cleaning), but also can improve the nylon staining fastness to more than 4.0 grade, and simultaneously shorten the process flow and improve the production efficiency.
Although the present invention has been described in detail by way of preferred embodiments, the present invention is not limited thereto. Various equivalent modifications or substitutions can be made on the embodiments of the present invention by those skilled in the art without departing from the spirit and scope of the present invention, and these modifications or substitutions are within the scope of the present invention/any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention.
