Description

Technical Field

[0001] The invention relates to the technical field of printing and dyeing, in particular to a pre-treatment process of Zhigong stretch fabric. Background Art

[0002] Printing and dyeing is a comprehensive process of physical and chemical treatment of textile fabrics, generally refers to adding patterns and designs on textile fabrics, changing the color of textile fabrics and related pre-treatment processes, etc. By causing physical or chemical changes between dyes and fibers, the textile fabrics will have a certain color and gloss. According to the different printing and dyeing objects, the printing and dyeing process can be divided into cotton textile printing and dyeing, linen textile printing and dyeing, wool textile dyeing and finishing, silk printing and dyeing, etc. The printing and dyeing wastewater has a large amount of water, high chroma, and complex composition. The nitro and amino compounds in the dye structure and heavy metal elements such as copper, chromium, zinc, and arsenic have greater biological toxicity, seriously pollute the environment, and need to be harmlessly treated before discharge.

[0003] However, some components contained in the printing and dyeing solution in the prior art will affect the coloring effect of the fabric, and thus affect the production quality of the fabric. Simple filtration cannot remove metals, colloids, organic matter, and inorganic matter in the printing and dyeing solution. Therefore, after some components in the printing and dyeing solution reach a certain concentration, the printing and dyeing solution needs to be discarded and discharged. The cost of solution treatment and discharge is high, and water resources are wasted. The production and processing process is not environmentally friendly. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that some components contained in the printing and dyeing solution in the prior art will affect the coloring effect of the fabric, thereby affecting the production quality of the fabric, and simple filtration cannot remove the metals, colloids, organic matter and inorganic matter in the printing and dyeing solution. Therefore, after some components in the printing and dyeing solution reach a certain concentration, the printing and dyeing solution needs to be discarded and discharged, the cost of solution treatment and discharge is high, and water resources are wasted. At the same time, the production and processing process is not environmentally friendly. The pre-treatment process of Zhigong stretch fabric is proposed.

[0005] In order to achieve the above object, the present invention adopts the following technical scheme: the pre-treatment process of Zhigong stretch fabric comprises the following steps: S1. Pretreatment: Check the quality of the fabric, verify the type of fabric, and clean the fabric after checking and verifying that it is correct; S2, desizing treatment: adding amylase into the padding tank, mixing by a stirring device to obtain a desizing solution, padding the fabric in S1 into the desizing solution, then fishing out the fabric and transferring it to the steamer through a transfer device; S3, fabric cleaning: the desizing fabric is placed in a cleaning tank filled with clean water for cleaning. An ultrasonic cleaning machine is placed in the cleaning tank. The ultrasonic cleaning machine drives the water in the cleaning tank to vibrate, so that the starch and starch hydrolysis products remaining on the outer surface of the fabric are separated after being impacted. The fabric is then taken out of the cleaning tank and rinsed with running water. S4, drying treatment: the cleaned cloth is clamped at one end by a clamp, the cloth is vertically suspended, and then a drying device is set sideways to dry the wet cloth; S5, singeing treatment: the cloth dried in S4 is transferred to the singeing equipment through the transmission equipment to burn off the excess fluff on the surface of the cloth.

[0006] S6. Dye preparation: select the dye corresponding to the fabric dyeing requirements, add it to the solution inside the printing and dyeing equipment, and then mix the dye and the solution through a stirring device to obtain a printing and dyeing solution; S7, fabric printing and dyeing: put the fabric and the printing and dyeing solution into the printing and dyeing equipment, seal the printing and dyeing equipment, use a booster pump to inject external air into the interior of the printing and dyeing equipment, heat the solution, color the fabric, then take out the colored fabric, wash the floating color, and put it into the dryer for drying; S8. Treatment of printing and dyeing solution: The solution in the printing and dyeing equipment is placed in two electrodes. The two electrode plates are made of A3 steel plate material. The solution is used as the dielectric. After direct current is passed through the plates, the negative electrode of the plate continuously dissolves to produce divalent iron ions, causing the color SS, COD, BOD and heavy metal ions such as arsenic and mercury in the solution to polymerize. Then, the same color dye is re-added to the filtered solution and the solution is reused.

[0007] By adopting the above technical scheme: through fabric desizing, fabric washing and drying, starch in the fabric is prevented from dissolving in the printing and dyeing solution, and the printing and dyeing solution is prevented from being contaminated, while the coloring of the fabric is not affected. In addition, the waste water after fabric printing and dyeing is removed by two powered electrodes and a filtering device, and then reused after adding an appropriate amount of dye, thereby reducing the cost of printing and dyeing wastewater treatment, saving water consumption during printing and dyeing, and saving energy and protecting the environment.

[0008] As a preferred implementation, in step S1: Pretreatment: Check whether the fabric has abnormalities such as drawn yarn, weft spots, yellow spots, etc., and check whether the fabric is consistent with the requirements. After verification, operate the transmission equipment to transfer the fabric to the cleaning equipment. The cleaning equipment collects and cleans the dust on the surface of the fabric with a cleaning brush.

[0009] By adopting the above technical solution: detect whether there is any abnormality in the fabric to avoid poor fabric quality and affect product quality, and clean the dust on the surface of the fabric through cleaning equipment to avoid dust being retained in the production process.

[0010] As a preferred implementation, in step S2: Desizing treatment: add amylase into the padding pool, mix through stirring equipment to obtain desizing solution, adjust the pH value of the desizing solution to make it neutral, immerse the fabric in the desizing solution for 10 minutes, and then transmit it to the steamer through the transmission equipment. The steamer heats the fabric with steam, the steam temperature is 95°C, and the heating time is 8 minutes.

[0011] By adopting the above technical solution: through steaming treatment, the molecular activity is improved, the starch attached to the surface of the cloth is quickly hydrolyzed, and the production efficiency is improved.

[0012] As a preferred implementation, in step S3: Fabric cleaning: Put the desizing fabric into a cleaning pool filled with clean water for cleaning. An ultrasonic cleaning machine is placed in the cleaning pool. The ultrasonic cleaning machine drives the water in the cleaning pool to vibrate. The frequency of the ultrasonic cleaning machine is 1100HZ, the water temperature is 40℃, and the cleaning time is 5min. The starch remaining on the outer surface of the fabric is separated after being impacted. Then, the fabric is taken out of the cleaning pool and rinsed with running water. The rinsed water is introduced into the interior of the cleaning pool. A filter is connected to one end of the cleaning pool. The filter filters impurities in the water. The starch and starch hydrolysis products in the water are filtered through a reverse osmosis membrane to obtain clean water for reuse. By adopting the above technical solution: the ultrasonic cleaning machine transmits vibration to the water, so that the water follows the vibration and continuously impacts the outer surface of the fabric, so that the starch attached to the outer surface of the fabric is separated, thereby improving the cleaning efficiency. At the same time, running water is used to clean the fabric to avoid starch hydrolysis products remaining on the fabric surface, thereby improving the cleaning effect.

[0013] As a preferred implementation, in step S4: Drying treatment: After cleaning, the cloth is clamped at one end by a clamp, the cloth is lifted up, and then a drying device is set sideways to dry the wet cloth. The drying temperature is 45°C, the drying time is 30 minutes, and the wind speed is 80m / s.

[0014] By adopting the above technical solution: the cloth after cleaning is placed in a drying room for drying, so as to avoid the damp cloth from diluting the dyeing solution, reduce the dyeing error and ensure the dyeing accuracy.

[0015] As a preferred implementation, in step S5: Singeing treatment: The fabric dried in S4 is transferred to the singeing equipment through the transmission equipment to burn off the excess fluff on the fabric surface. The singeing temperature is 800℃.

[0016] By adopting the above technical solution, the lint on the surface of the cloth is burned off by the singeing equipment to ensure that the cloth is clean.

[0017] As a preferred implementation, in step S6: Dye preparation: Select the dye in the corresponding proportion of the fabric dyeing requirements and add it to the solution inside the printing and dyeing equipment, and then mix the dye and solution through a mixer. The mixer speed is 650r / min and the stirring time is 2min.

[0018] By adopting the above technical solution: the mixer fully mixes the dye and the solution, thereby improving the mixing efficiency, avoiding uneven coloring of the cloth caused by uneven mixing of the dye and the solution, and ensuring production quality.

[0019] As a preferred implementation, in step S7: Fabric printing and dyeing: Put the fabric into the printing and dyeing equipment, seal the printing and dyeing equipment, use a booster pump to inject external air into the interior of the printing and dyeing equipment, make the internal air pressure of the printing and dyeing equipment 300mpa, then heat the solution to 125℃ for 30min, then use a booster pump to inject external air into the interior of the printing and dyeing equipment. The internal air pressure of the printing and dyeing equipment is 400mpa, and the solution temperature is heated to 135℃ for 20min to color the fabric, then take out the colored fabric, clean the floating color and put it in a dryer to dry.

[0020] By adopting the above technical solution: by increasing the pressure inside the printing and dyeing equipment in a step-by-step manner, the boiling point of the solution is increased to prevent the cloth from being affected by bubbles when the solution boils, resulting in uneven dyeing. At the same time, the pressure is increased to accelerate the movement speed of molecules in the solution and improve the dyeing efficiency of the cloth.

[0021] As a preferred implementation, in step S8: Printing and dyeing solution treatment: put the solution in the printing and dyeing equipment into two electrodes. The two electrode plates are made of A3 steel plate material. The solution is used as the dielectric. After the plates are passed with direct current, the negative electrode of the plate continuously dissolves to produce divalent iron ions, and produces hydrogen and new ecological oxygen. Water is electrolyzed into hydrogen ions and hydroxide ions. Hydroxyl ions and iron ions generate ferrous hydroxide. Ferrous hydroxide reacts with oxygen in the air to generate hydroxyl complexes and develop into inorganic polymer electrolytes. This type of product acts as a coagulant to polymerize the color SS, COD, BOD and heavy metal ions such as arsenic and mercury in the solution. Hydrogen ions obtain electrons at the cathode to generate hydrogen. In the process of hydrogen floating, the dye molecules decolorized by new ecological oxygen float to the water surface to form scum under the surface tension of hydrogen bubbles. The scum is scraped off, and then the solution is introduced into the filtration equipment through a water pump. The water outlet of the filtration equipment introduces the filtered solution into the printing and dyeing equipment to remove the particles, fibers, and sediments in the solution. Then, the same color dye is re-added to the filtered solution to reuse the solution.
