What is transfer printing?

Question 1: What is one of the printing methods of transfer printing textiles? Started in the late 1960s. A printing method in which a dye is first printed on other materials such as paper, and then the pattern is transferred to the fabric by hot pressing. It is mostly used for printing chemical fiber knitwear and clothing. Transfer printing should go through the processes of dye sublimation, migration, melting and ink layer peeling. Transfer printing is to print the dye on transfer printing paper first, and then transfer the dye in the sea pattern to the textile by heat treatment during transfer printing, and fix it to form a pattern. At present, the widely used transfer printing method is dry transfer of disperse dyes on synthetic fiber fabrics. In this method, disperse dyes, paste powder (Shanghai Sixi Chemical Industry), alcohol, benzene and other solvents are mixed with resin to make ink, which is printed on tough paper to make transfer paper. When printing, the patterned side of transfer paper overlaps with the fabric. After hot pressing at high temperature (220 degrees) for about 65438±0min, the disperse dyes sublimate into gaseous state and transfer from the paper to the fabric. After printing, there is no need to wash with water, no sewage is produced, and the effect of bright colors, distinct layers and exquisite flower shapes can be obtained. However, the existing ecological problems, in addition to dyes and additives in color paste, also need a lot of transfer paper, which is difficult to recycle after printing in transfer paper.

Question 2: What is the material of transfer printing? Let me answer:

1. transfer printing refers to the transfer printing technology with needle textiles as the carrier. With the improvement of transfer printing, it is also widely used in nylon, acrylonitrile, cotton, hemp, wool and so on.

Two: transfer printing fabric (cloth) can be divided into wet method, dry method, steam method, vacuum method, thermal method and other forms.

Three: transfer printing fabric (cloth) characteristics:

(1) The pattern of transfer printing fabric (cloth) has the characteristics of vivid pattern, rich and clear layers, meticulous pattern, high artistry and strong three-dimensional sense.

(2) The transfer printing fabric (cloth) has no environmental pollution problem. Because it is dry processing, there is no need for washing, steaming, drying and other processes, so there is no waste gas and wastewater discharge, and the fabric itself is very environmentally friendly and healthy.

(3) The dye of the transfer printed fabric (cloth) is fully sublimated and fixed on the fiber below 2 10℃, and good washing fastness and ironing fastness can be obtained.

(4) The dye of transfer printing fabric (cloth) is bright and bright.

Question 3: Advantages of transfer printing Transfer printing can be used not only for synthetic fiber fabrics, but also for natural fiber pure spinning and its blended fabrics. Has the following advantages: (1) no water and no sewage; (2) The process flow is short, the finished product is printed, and post-treatment processes such as steaming and water washing are not needed; (3) Fine patterns, rich and clear levels, high artistry and strong three-dimensional sense, which can not be printed by general methods, and can be printed with photography and painting styles; (4) The printing color is bright, and the tar in the dye stays on the transfer paper during sublimation, which will not pollute the fabric; (5) The product rate is high, and multiple sets of color patterns can be printed at one time without cross-checking; (6) The flexibility is strong, and the pattern can be printed in a short time after the customer selects it.

Question 4: What fabric can be used for transfer printing? The fabrics that can convert heat to clothes are polyester cotton, polyester cloth, chiffon, satin cloth, short plush, peach skin, suede, canvas, Oxford cloth, mesh cloth, non-woven fabric and so on. Contact information

Question 5: What is the difference between digital printing and transfer printing? According to the process, printing can be divided into two types:

1. Traditional printing

2. Digital printing

Traditional printing is divided into many branches, and its heat transfer (gravure printing) belongs to its small branch process.

Traditional thermal transfer printing is mainly used for fabric, chemical fiber and polyester. Disperse inks and thermal transfer inks are also used for printing. Transfer paper adopts Heidelberg, electro-engraving and other processes for high-temperature printing, which is suitable for printing with large amount of color registration and few colors.

Its advantages are bright colors, high speed and low cost.

Disadvantages: color matching is troublesome, and opening the board is troublesome.

Digital printing is a new printing technology. Using inkjet printer to realize printing technology is suitable for the needs of various industries, and can produce a large number of colors and achieve perfect gradient effect.

Digital printing is divided into several categories according to its fabrics and inks:

A. thermal transfer printing

B. Active direct injection

Direct injection of C acid

D. Direct spraying of paint

At present, the main digital printing process on the market belongs to thermal transfer printing, which is similar to gravure printing, mainly using printers for printing and transfer paper for high-temperature transfer printing.

Suitable for smallpox, polyester, chemical fiber, ribbon and other industries.

Question 6: Transfer printing of ready-to-wear printing As the name implies, the clothes that can be worn have been made and printed in the transfer printing factory. Because the front and back pieces and sleeves of the finished clothes have been sewn together, it is more difficult to transfer printing than simple cloth pieces. The reasons can be summarized as follows for readers' reference and please correct me. Thank you! First, the problem of clothes wrinkling is transferred to the customers of garment factories and printing factories. The space distance between the two factories is sometimes close and sometimes far. Imagine: a commodity with clothes is sewn into clothes by a clothing factory, then counted, bundled, packaged, stacked, loaded and transported to a transfer printing factory. After all this trouble, after the transfer printing factory received the goods and opened the box, all the clothes in the box became Zou Baba's. If you don't finish, how to do transfer printing? In view of the above problems, it is suggested to do this: (1) As a responsible transfer printing factory, it is necessary to require this garment factory to iron the finished clothes, put them into rigid cartons (preferably not woven bags) and then deliver them to the transfer printing factory. (2) The first thing the transfer printing factory does after receiving a load of clothes: count the quantity of goods and register them one by one. The team leader will deliver the goods to the transfer printing workshop for registration and report them to the printing business office for retention. (3) Check whether the clothes are damaged, polluted and wrinkled. If you find wrinkled clothes, send them back to the garment factory for ironing when the quantity is large. If the quantity is small, start ironing yourself. Second, the color difference between the front and back of clothes is the transfer printing of a garment. According to common sense and objective reasons, one side must be printed before the other. At this time, many transfer printing factories often find that the front color and back color are inconsistent after double-sided printing, and sometimes there is a big difference. Imagine how to return this dress to the customer. Care about others, how do customers sell? Solution: (1) If the front mask is printed first, after printing, try to cool the clothes to room temperature before printing the back mask. (2) A class must print out all the front and back of each dress before coming off work. It is forbidden to print the first film in the morning and then come back in the afternoon (or concentrate on memorizing the film at night). (3) Don't transfer the clothes that have just been ironed with a steam iron immediately, and transfer printing should be carried out after the residual steam volatilizes naturally. If a transfer printing factory can treat every customer and every piece of clothing seriously and responsibly, and correct it in time when problems are found, how can it not print well? You should know that the printing cost is the same whether the printing quality is good or bad. The printing quality is not necessarily poor, and the cost will be lower. On the contrary, the printing quality is high and the cost is not necessarily high.
