\n1. Printing preparation stage
\nMaterial pretreatment: Accurately embed the PET film into the printer tray, and make sure that the film is flat and wrinkle-free. It is recommended to use equipment with a vacuum adsorption platform to avoid displacement of the film during printing.
\nMirror printing technology: Set the horizontal flip parameter in the RIP software to ensure that the final pattern direction is consistent with the direction of the fabric presentation. The printing resolution is recommended to be set above 1200\u00d71200DPI to ensure line accuracy.
\nDTF primer process: Using CMYK+W five-color printing mode, the thickness of the white ink layer needs to be controlled in the range of 8-12\u03bcm. Tests show that this thickness range can achieve the best balance between color reproduction and film transmittance.<\/p>\n
\nIntelligent powder shaking device: equipped with a powder spreader with adjustable vibration frequency, it is recommended to use a 45\u00b0 inclination angle to evenly drop powder. The powder particle size needs to be tested by a 200-mesh sieve. Too large particles are prone to uneven melting.
\nCirculation recovery system: Design a closed powder recovery channel, the recovery rate of unattached powder can reach more than 95%, significantly reducing material loss.
\nPowder melting process window: The temperature of the hot press is set at 160-170\u2103, and the time accuracy needs to be controlled within \u00b15 seconds. Actual measured data shows that this parameter range can make the hot melt powder melting index reach the ideal state of 8-12g\/10min.<\/p>\n
\nCloth pretreatment: Use 180\u2103 rapid pre-pressing for 3 seconds, which can effectively remove the air between the fabric fibers and improve the transfer yield.
\nControl of three elements of transfer printing:
\nTemperature: 165\u2103\u00b12\u2103 (it is recommended to configure an infrared thermometer for real-time monitoring)
\nPressure: 0.35-0.45MPa (dynamically adjusted according to the thickness of the fabric)
\nTime: 18 seconds (cotton fabric can be extended to 22 seconds)
\nCooling and peeling process: The forced air cooling system needs to reduce the film temperature to below 40\u2103 within 5 seconds. Peeling too early will cause color migration, and peeling too late may cause false adhesion.<\/p>\n
\n1. Printer configuration standards
\nNozzle type: industrial-grade piezoelectric nozzle (such as Epson I3200 series)
\nInk system: equipped with a secondary ink filter device, filter accuracy \u22641\u03bcm
\nNegative pressure control: dynamic ink pressure adjustment range -2.5 to +1.5kPa<\/p>\n
\nHeating plate material: 6061 aluminum alloy substrate + Teflon coating
\nTemperature control accuracy: \u00b11\u2103 (PID intelligent temperature control module)
\nPressure sensor: range 0-500N, resolution 0.1N<\/p>\n
\nActivated carbon adsorption device: for trace VOCs generated by the hot pressing process, the treatment efficiency is \u226590%
\nElectrostatic dust removal system: configure ion wind rods in the front section of printing to eliminate electrostatic accumulation of film materials<\/p>\n
\n1. Adhesion test standard
\nRefer to ASTM D3359 standard performs tape test, requiring 5B grade (no peeling of the edge of the grid)
\nWater washing test: 40\u2103 warm water machine wash 50 times, color fastness \u22654 grade (AATCC 61-2013 standard)<\/p>\n
\nBubbles\/wrinkles: check the parallelism of the heat press and adjust the pressure uniformity
\nColor deviation: calibrate the ICC curve and update the nozzle waveform file
\nFilm material residue: optimize the melting powder process parameters and extend the cooling time<\/p>\n
\nDaily: clean the nozzle surface and detect the negative pressure value
\nWeekly: calibrate the temperature control system and replace the filter cotton
\nMonthly: perform deep cleaning of the nozzle and check the accuracy of the pressure sensor<\/p>\n
\n1. Personal protective equipment
\nAnti-scalding gloves: temperature resistance \u2265200\u2103, in line with EN 407 standards
\nGoggles: pass the ANSI Z87.1 impact test
\nDust mask: filtration efficiency above N95 level<\/p>\n
\nEquipment grounding resistance \u2264 4\u03a9
\nEmergency stop device response time < 0.2 seconds
\nPower isolation transformer complies with IEC 61558 standard<\/p>\n
\nWaste film recycling: Cooperate with professional institutions to achieve PET material recycling
\nWaste ink treatment: Entrust qualified units to dispose of hazardous waste and establish a transfer joint form system
\nBy strictly implementing the above process specifications, the yield of DTF film can be increased to more than 98%, while reducing the overall production cost by 20%. With the integration and development of intelligent equipment and new material technology, this process will show broader application prospects in the field of personalized customization.<\/p>","protected":false},"excerpt":{"rendered":"
