Classification and application of thermal transfer lanyards
The thermal transfer lanyard is to design the pattern, make a copper plate, and then engrave the pattern on the copper plate by color by electro-engraving machine. Then take the copper plate to the printing machine to print the pattern on the PET film, and then transfer the pattern to the product through the thermal transfer lanyard machine.
Thermal transfer lanyard technology has been used in fabric thermal transfer printing production for a long time. With the rapid development of high technology, thermal transfer lanyard technology has become more and more widely used. There are hot press transfer type and thermal sublimation transfer type from the classification of ink varieties. There are fabrics, plastics (plates, sheets, films), ceramics and metal coated plates, etc. from the transferred materials; from the classification of printing methods, it can be divided into screen printing, flat printing, gravure printing, letterpress printing, inkjet and ribbon Printing, etc.; from the substrates, there are thermal transfer lanyard paper and thermal transfer lanyard plastic film.
The thermal transfer lanyard LOGO ink has no texture, and the three-dimensional effect is not as strong as silk screen printing. The ink not only adheres to the surface of the webbing, but also partially penetrates into the webbing.
Thermal transfer lanyard lanyard is a process in which the text or pattern is first printed on the thermal transfer paper, and then the text or pattern on the paper is accurately transferred to the webbing by the thermal transfer lanyard machine under high temperature and high pressure. Pressurized transfer embossing process. Taking polyester as an example, the appropriate process conditions should be at 205 ° C for 20 to 30 s. But at 170 ~ 180 ℃ and 10s, the effect is not good. At 180 ~ 190 ℃ and 15 ~ 10s, only the ring dyeing effect can be achieved. Such as 230 ~ 240 ℃ and above 40s, the hand feel is rough, and if it is above 240 ℃ and 45s, it is close to melting. Different types of fabric fibers have different transfer conditions.
In addition to temperature and time, the pressure during transfer printing is also a very important condition. If the pressure is too small, the gap between the fabric and the flower paper will be large, and the yarn will be round, so that the dye gas molecules collide with the air and escape, resulting in poor effect, and the dye is also easy to seep, the lines are thick and the patterns are blurred. If the pressure is increased, the yarn can become flat, the gap between the fabric and the decal is small, the transfer coloring effect is good, the pattern is clear, and the lines are smooth and fine. However, if the pressure is too high, it will cause deformation, fluff, and the shape of the heavy fabric will change, and will produce aurora, resulting in rough hand feel and color surface defects.
The pattern of the heat transfer lanyard lanyard is transferred to the webbing at one time, whether it is single color or multi-color, so the color of the LOGO has little relationship with the printing cost (only the difference in plate making). The heat transfer lanyard process is especially suitable for printing full-color images or colorful and complex patterns.
At present, the popular and common thermal transfer lanyards at home and abroad are 50px wide, and some people who like smaller ones will use 37.5px wide. The perimeter of the commonly used webbing is 2250px long (the webbing is 1125px long after the webbing is folded in half). The thermal transfer lanyard pattern can be printed all over the edge, that is, the width of the thermal transfer lanyard pattern can be the same as the width of the webbing.
Usually heat transfer lanyard lanyard - belongs to the category of textile accessories (other names: mobile phone rope, lanyard, lanyard). Generally, lanyards are made of nylon, pp, polyester, high-elastic cotton, and the general specifications are 4mm wide , 5mm, 6mm, 7mm, 8mm, 10mm, 12mm, 16mm, 20mm, 25mm.
The content of the thermal transfer lanyard can be the company name, website, main contact information, product brand, publicity slogan, slogan, or the name of sports events, concerts, commercial activities, parties and other LOGOs. Nylon, cotton, bamboo fiber, etc. cannot withstand high temperature, and require special and high-cost processing to heat transfer lanyards. Therefore, whether at home or abroad, the proportion of polyester material used in the thermal transfer lanyard lanyard webbing on the market is as high as 99%.
In order for the majority of users to customize the personalized lanyard to their own LOGO conveniently, quickly and economically, especially to meet the customization of small batches and reduce the customization threshold of customers, based on years of production experience, combined with domestic and foreign For the customization and usage habits of lanyard products, Foshan Tule Ribbon Craft Factory has specially selected 3 series that are general, common and popular.
