Selection of digital printing equipment
Because people to the personalized demand of clothing, textile clothing fabric field also tends to be personalized, comfortable.Digital printing process is more and more popular because of its high precision, no need for platemaking, flexible batch, environmental protection and small footprint.However, how to choose a suitable textile digital printing machine has become a new problem.This paper discusses several factors that need to be considered in the selection of textile digital printing machine.
1. Selection of printing process
The choice of printing technology directly determines the type of digital printing machine.For garment fabric printing, it is a choice of transfer printing process or direct injection process, which has a decisive role in the selection of digital printing machine.Transfer printing technology investment is small, printing precision is high, but the applicable fabric is limited, mainly applicable to chemical fiber fabric.The direct spraying process generally requires such links as fabric sizing, evaporation and washing, which is relatively large in investment. However, the fabric is applicable to a wide range of fabric types, including polyester, nylon, cotton, linen, silk, wool and mordale.
2. Selection of fabric form
Fabric form is to point to be rolled cloth, cut piece, sweater or garment.According to the main types of production and processing fabrics, enterprises can decide to choose the digital printing machine is the printing cloth, cutting, sweater or clothing.
3. Selection of printing precision
According to the different fabrics and customer needs, the enterprise can choose the printing precision of customer equipment.Generally speaking, the fiber is more exquisite and smooth fabric precision requirements are higher, such as silk, chiffon, etc.The demand of the fabric that fiber compares coarse to accuracy is inferior, for instance canvas, sweater.When choosing printing precision, it should be noted that the higher the precision, the better, because precision and efficiency are two opposite factors. If the precision is required, the lower the efficiency.
Choice of printing ink
Printing ink options are generally three;
The first is the color selection of the printing ink.According to the customer's needs and fabric type, can choose four ink, six ink, eight ink.The more ink color, the better the printing color saturation and color effect, also directly determine the printing machine color type.
The second is the type selection of printing ink.Printing ink generally has reactive ink, acid ink, disperse ink, paint ink and several other ink.Ink type should be chosen according to the material of the fabric in general, choice of fabric color is better, color performance of ink.
The third point is the choice of ink brand and model.Generally speaking, the ink is developed for the brand and model of the sprinkler, the selection of ink should pay attention to whether it is applicable to the printer's sprinkler model.In addition, ink fluidity, bright-coloured degree, fixative degree, environmental protection degree, etc., is the aspect that ink choice should consider.
The core of digital printing machine: the choice of sprinkler head
As the most important part and main consumables of digital printing machine, the sprinkler head plays a decisive role in the selection of digital printing machine.The type of sprinkler head determines the accuracy of printing, the size of ink-jet, printing speed, production cost and so on.The selection of sprinkler head should take into account the type of printed fabric, cost estimation, production efficiency requirements and other factors comprehensively. As the main consumables, sprinkler head should also consider the cost and durability of replacement comprehensively.
Do you prefer domestic printing machine or imported printing machine?
Due to the progress of science and technology and the maturity of manufacturing technology, the gap between domestic digital printing machine and import machine has been getting smaller and smaller.The enterprise chooses the domestic digital printing machine or the import digital printing machine, mainly needs to consider the following factors.
First, cost.Because of the import equipment has tariff and freight, the price of imported digital printing machine is higher than that of similar domestic digital printing machine.
Second, key technologies.As the key part of digital printing machine - sprinkler head, are basically imported, mainly produced in Japan.So whether domestic digital printing machine or imported digital printing machine, the key equipment used is basically the same.
Third, after-sales service.Whether domestic equipment or imported equipment, good after-sales service is one of the important factors for the selection of digital printing machine.The efficiency and cost of production are directly determined by the timeliness and effectiveness of solving problems.
The technical ability and sustainable development of the manufacturer
When choosing digital printing machine, we should focus on the technical ability and sustainable development ability of the manufacturer, which are mainly shown in:
(1) what is the r&d strength of the manufacturer?The r&d force of the manufacturer decides to choose the market competitiveness of the products of the manufacturer, whether the equipment used can keep pace with The Times, whether can upgrade and transform, and whether can have a new generation of products to meet the requirements of future development.
(2) the manufacturer's support for the whole process.In particular, direct - jet digital printing process is relatively complex.There are such links as fabric sizing, printing and drying, evaporation, water washing and finishing, etc., in which any control error will affect the quality of the final product.
Therefore, it is especially important to get the technical support from the manufacturer for the whole process, which is embodied in the cooperation between slurry and fabric, ink and machine and sprinkler, steaming, washing, finishing and printing, etc.
8 other factors
The following factors should be considered before the final selection of textile digital printing equipment:
(1) printing costs.That is, the comprehensive calculation of equipment depreciation, ink consumption, sprinkler consumption, plant rent, water and electricity charges, labor costs, etc. calculated the comprehensive cost of printing finished products per square meter.
(2) floor space and environmental conditions required for the equipment.To measure the floor space required by the equipment and whether the temperature and humidity required by the environment are met.
(3) water, electricity and gas requirements.To understand the equipment power, voltage, pressure, and other specific requirements.
These are the factors to be considered when choosing a digital textile printing machine.
Choose the basic principle of digital printing machine - do not choose the most expensive, only choose the most suitable for their own.
