Description
Technical Field
The invention belongs to the field of fabric dyeing and finishing, and particularly relates to a continuous pad dyeing method and equipment for nylon elastic fabric.
Background
Nylon, also known as nylon, is the trade name for synthetic polyamide fibers. Because a large number of hydrophilic amide groups exist in nylon molecules and the chain ends are amino groups and carboxyl groups capable of being ionized, acid or neutral dyes are generally selected for nylon dyeing. However, due to the special property of nylon molecules, amino groups and carboxyl groups capable of generating strong ionic bonds for dyes are few, and most dyes can be bonded on the nylon molecules only through weak van der waals force and hydrogen bonds formed by the dyes and amide groups, so that the nylon fabric needs to be dyed through multiple fixation steps. On the other hand, in order to enhance the wear resistance and the resilience of the nylon fabric, most of the nylon fabrics are added with spandex and other elastic fibers, so that the technical difficulty of the nylon fabric dyeing and finishing process is further increased.
The existing nylon fabric dyeing technology, such as overflow dyeing machine and warp beam dyeing machine, is easy to cause uneven dyeing, and can not meet the high quality requirement of consumers on the garment fabric. On the other hand, the overflow dyeing and warp beam dyeing technology needs to be suitable for a large amount of energy sources such as water, heat, electricity and the like, is not environment-friendly and has higher production cost.
Based on the defects of the two processes, the pad dyeing process is gradually valued by the dyeing and finishing industry due to the advantages of reducing energy consumption and water consumption. However, the existing padding process is still poor in adaptability to nylon elastic fabrics, and is easy to cause uneven dyeing problems such as folds, wicker prints and the like. And the nylon fabric continuous pad dyeing process generally needs steam color fixation, still has higher energy consumption demand, and can generate a large amount of dyeing wastewater.
According to the patent CN112609477A, by scouring, bleaching and qualitative determination before printing and dyeing, the nylon fabric is guaranteed to be flat in cloth surface and uniform in dyeing in continuous pad dyeing, and the problem that the nylon elastic fabric is not uniformly dyed can be solved. But the scouring, bleaching and qualitative before tie-dyeing increase the process flow on one hand, and the high-temperature working environment increases the production cost. On the other hand, hydrogen peroxide, sodium hydroxide and other scouring and bleaching working liquids used for scouring and bleaching increase sewage discharge, and are not beneficial to environmental protection.

Detailed Description
The nylon fabric is dyed by overflow dyeing machine or beam dyeing machine. Both of these dyeing processes have certain disadvantages for nylon fabrics, especially nylon elastic fabrics. The overflow dyeing machine is easy to have chicken feet print, the warp beam dyeing machine can not have chicken feet print, but the quality of the rolled paper has great influence on the dyeing quality, and the rolled paper is too loose and too tight, so that uneven dyeing such as wood grain printing can be realized. The overflow dyeing needs a large amount of water, and the warp beam dyeing machine needs a high-temperature and high-pressure environment for working, so that the dyeing cost of the two is high.
On the other hand, the existing overflow dyeing and warp beam dyeing technologies suitable for nylon dyeing cannot realize continuous production. For beam dyeing, manual borrowing is required between fabric rolling, pre-treatment, dyeing and post-treatment, and the fabric is transported between independent devices. Similar problems exist in overflow dyeing, which in turn limits the improvement of production efficiency.
Although at present, a plurality of dyeing enterprises begin to select a continuous pad dyeing process to dye nylon fabrics, so that the energy demand is reduced and the process cost is reduced. However, the continuous pad dyeing process still has certain drawbacks. On one hand, because the tension of the nylon elastic fabric is difficult to control, wrinkles are easy to appear in the pad dyeing process, and the dyeing is uneven. On the other hand, the nylon fabric dyed by the acid or neutral dye generally needs to be subjected to steam fixation, and the steam fixation may also cause uneven dyeing.
The principle of steam fixation is through the popped textile fabric fibre of saturated steam, inside making the entering fibre that the dyestuff can be better, simultaneously can also make the better entering fibre of dyestuff molecule inside through the pressure that steam produced. However, since both neutral dyes and acid dyes are water-soluble dyes, when steam passes through the surface of the fiber during fixation, the attraction force formed between water molecules and dye molecules is greater than the force formed between the dye and the fiber, and thus the water molecules carry away a part of the dye adsorbed on the fiber. This not only reduces the dyeing effect, but also prevents the secondary use of the dye dissolved in water, resulting in a large amount of dyeing wastewater which is difficult to treat. Meanwhile, in the steam color fixing process, the cloth is often in a loose suspension state, the tension of the cloth surface is difficult to control, wrinkles and uneven dyeing of the cloth are easily caused, or the cloth in contact with a cloth guide roller cannot be fully contacted with steam, so that the problem that the color difference exists in the whole cloth is caused.
The invention can realize the effect of uniform dyeing by fixing color by using a liquid organic color fixing medium incompatible with water. The fixation principle is that because the acid dye or the water-based dye can be dissolved in water, the solubility in the fixation medium is very low. The dye molecules are selectively attached to the cloth instead of being taken away by the color fixing medium, so that the color fixing purpose is achieved. Meanwhile, as the dye is not dissolved in the color fixing medium, the color fixing medium is not polluted by the dye, and can be recycled, thereby reducing the dyeing cost. And from the on the other hand, because the liquid fixation medium of chooseing for use in the fixation device, consequently can install tension induction system additional in the fixation case and monitor cloth cover tension, prevent that the cloth cover from producing the fold and causing the dyeing inequality.
The continuous pad dyeing process of the nylon elastic fabric can be applied to the continuous pad dyeing device designed by the invention, so that the continuous, automatic and streamlined production of the nylon elastic fabric is realized.
FIG. 1 is a continuous pad-dyeing washing machine to which the present invention can be applied. As shown in fig. 1, the dyeing apparatus comprises a cloth feeding device 4, a dyeing device 1, a color fixing device 2, a washing device 3, a cloth discharging device 5 and the like.
Firstly, a dye solution is prepared in advance and added into a material groove of a evenness calender. The dye solution for dyeing the nylon elastic fabric comprises 0.1-100 g/L neutral or acid dye, 0.1-10 g/L acid and 0.1-10 g/L penetrating fluid. And feeding the cloth to be dyed into a uniform padder through a cloth feeding frame for padding. The cloth feeding frame is preferably a cloth feeding frame with a function of neutralizing and spreading cloth so as to ensure that the cloth is flat and has no wrinkles when being fed into a rolling mill.
Preferably, the padded fabric is preheated to prevent dye migration and uneven dyeing due to sudden temperature rise.
Subsequently, the cloth is fed into a fixation box filled with a liquid fixation medium through a cloth guide roller. The color fixing medium in the color fixing box is an organic solvent incompatible with water. The color fixing medium has the physical properties of low viscosity, low surface tension and high boiling point. Wherein the viscosity of the fixing medium is generally less than 200mm2The surface tension is 15 to 40dyn/cm, and the boiling point is 100 to 400 ℃. The cloth stays in the color fixing box for 30s to 3min, and the temperature in the color fixing box is maintained at 50 to 130 ℃. The color fixing time and temperature can effectively realize the glass fiber of the fiber, improve the dye uptake, and simultaneouslyPrevent the fiber from being damaged by excessive heating.
Preferably, a group of same color fixing procedures is added to achieve the purpose of improving the color fixing effect.
Meanwhile, the cloth guide rollers used for conveying the cloth in the color fixing box are driving rollers. The cloth guide roller is driven by a motor, and the rotating speed can be controlled. Meanwhile, the cloth guide roller rotates actively to drive the cloth to be conveyed, and compared with a driven roller, the cloth guide roller can reduce the friction force between the cloth and the roller, so that the defects caused by the scratch of the cloth surface are reduced.
In order to further prevent that the cloth in the fixation stage from producing the fold in the transfer process, the fixation incasement is equipped with tension sensor and detects cloth tension. By analyzing the numerical value of the cloth cover tension, the rotating speed of the cloth guide roller is adjusted, and the cloth cover tension is maintained between 5 kg and 100 kg. Thereby preventing the cloth from curling due to over-high tension, or preventing dyeing defects such as wrinkles, wicker marks and the like due to over-low tension.
Preferably, the cloth after color fixation is sent to a heavy padder for heavy rolling. And (3) rolling the cloth by a double-roller or three-roller heavy padder to remove redundant color fixing media, and recovering the cloth by a liquid tank on the padder.
And after the cloth is rolled again, the cloth is sent into a washing device for washing. The washing procedures comprise warm water washing, soaping, hot water washing and the like. Tension sensors can be arranged in each washing device to ensure that the cloth surface is smooth and does not wrinkle in the washing process. Meanwhile, the washing device can be additionally provided with a circulating showering system with a temperature control function, the temperature of washing water can be controlled to be 20-100 ℃, circulating showering can achieve the purposes of circulating water and reducing sewage discharge and water consumption. After each washing procedure such as warm water washing, soaping, hot water washing and the like is finished, the fabric is rolled by a padder to remove redundant water, and then the next washing procedure is carried out.
Preferably, after washing, the cloth is rolled again by a double-roller or three-roller heavy padder, and water absorbed in the cloth is removed by rolling to obtain the dyed cloth.
The technical solution of the present invention is further described in detail by the following examples.
