Description

Technical Field

[0001] The present invention relates to the field of printing technology, and particularly to a spraying and printing method for special materials and its fabric. Background Art

[0002] Traditional printing technologies, such as UV printing and heat transfer printing. UV printing is a printing process that dries and cures ink through ultraviolet light, and it requires the cooperation of ink containing photosensitizer and UV curing lamp. UV printing is relatively common in the printing industry. Heat transfer printing is another prominent technology in the printing industry. This printing method is divided into two major parts: transfer film printing and transfer processing. Transfer film printing uses dot printing (resolution up to 300 dpi). The pattern is pre-printed on the surface of the film. The printed pattern has rich levels, bright colors, is ever-changing, has small color differences, good reproducibility, can achieve the required effect of the designed pattern, and is suitable for mass production.

[0003] Traditional printing processes usually perform color printing on textiles, but for some special materials, such as fiberboards, leather, etc., traditional printing technologies have limitations and the printing effect is greatly reduced.

[0004] When traditional printing processes add auxiliary materials, more processing steps are required to ensure that the auxiliary materials are successfully added to the output product, which undoubtedly increases the preparation time and reduces the preparation efficiency. Summary of the Invention

[0005] Other features and advantages of the present invention will be described in the following specification, and will become partially obvious from the specification, or be understood by implementing the present invention. The objectives and other advantages of the present invention can be achieved and obtained through the structures specifically pointed out in the specification and other specification drawings.

[0006] The objective of the present invention is to overcome the above deficiencies and provide a spraying and printing method for special materials and its fabric.

[0007] To achieve the above objective, the technical solution of the present invention is: a spraying and printing method for special materials, including the following steps:

[0008] Step 1: The printing equipment locates the printing area, the equipment identifies and locks the printing area, and controls the nozzle assembly on the machine table to perform base printing on the special material first. There are several digital nozzles on the nozzle assembly;

[0009] Step 2: Identify the base printing area to determine the auxiliary material dispersion area. There is a module assembly on the nozzle assembly for storing and assisting in ejecting the auxiliary materials required for the special material. The auxiliary materials are powder, sequins, particulate matter or flocculent matter with visual effects, and the aperture of the corresponding digital nozzle is at least larger than the size of the auxiliary material;

[0010] Step 3: The control module component evenly sprays the auxiliary materials. After the printing device outputs the water-based ink, the auxiliary materials are evenly sprayed at regular intervals to form the pattern of the spray painting.

[0011] Step 4: Perform post-drying treatment to ensure that the spray-painted pattern is fixed.

[0012] In some embodiments, a water-based ink cartridge group, a white ink cartridge, and a curing agent cartridge are further provided on the nozzle component. The water-based ink cartridge group, the white ink cartridge, the curing agent cartridge, and the module component move synchronously with the digital nozzle. The water-based ink group includes water-based inks of multiple colors.

[0013] In some embodiments, the water-based ink is made of biodegradable materials.

[0014] In some embodiments, after the printing device outputs the water-based ink, the auxiliary materials are evenly sprayed at intervals of 0.1 - 0.5 s.

[0015] In some embodiments, the powder materials with visual effects include fluorescent powder, bright powder, and reflective powder.

[0016] In some embodiments, the particulate matter includes foaming particles and TPU particles.

[0017] In some embodiments, the spray printing method is used for printing on textiles, fiberboards, and leather.

[0018] In some embodiments, the textiles include woven fabrics and knitted fabrics.

[0019] A kind of fabric is made by using the above-mentioned spray printing method with special materials, and it is applied to shoe materials, clothing, and luggage.

[0020] By adopting the above technical solutions, the beneficial effects of the present invention are as follows:

[0021] In the spray printing method of the present invention, the water-based ink, the fixing agent, and the auxiliary materials are output by means of inkjet to form a pattern. During the spray painting, the auxiliary materials can be preliminarily fixed by the viscosity of the water-based ink and the fixing agent itself. The preparation time is greatly shortened and the preparation efficiency is high. The finished product patterns, textures, and styles output by the spray printing method of the present invention are more colorful and novel.

[0033] According to some embodiments of the present invention, the present invention provides a spraying and printing method for a special material, including the following steps:

[0034] Step 1: The printing device locates the printing area, the device identifies and locks the printing area, and controls the nozzle assembly on the machine table to perform base printing on the special material first. A number of digital nozzles are provided on the nozzle assembly;

[0035] Step 2: Identify the base printing area to determine the auxiliary material dispersion area.

[0038] According to some embodiments of the present invention, optionally, a water-based ink cartridge group, a white ink cartridge, and a curing agent cartridge are further provided on the nozzle assembly. The water-based ink cartridge group, the white ink cartridge, the curing agent cartridge, the module assembly, and the digital nozzles move synchronously. The water-based ink group includes water-based inks of various colors.

[0039] According to some embodiments of the present invention, optionally, the water-based ink is made of degradable materials.

[0040] According to some embodiments of the present invention, optionally, after the printing device outputs the water-based ink, the auxiliary materials are uniformly ejected at intervals of 0.1 - 0.5 s.

[0041] According to some embodiments of the present invention, optionally, the powdery material with visual effects includes fluorescent powder, bright powder, and reflective powder.

[0042] According to some embodiments of the present invention, optionally, the particulate matter includes foamed particles and TPU particles.

[0045] A fabric is made by using the spray painting and printing method of the above special material and is applied to shoe materials, clothing, and luggage.

[0046] Example 1

[0047] This example provides a spray painting and printing method for a special material, including the following steps:

[0048] Step 1: The printing equipment locates the printing area, the equipment identifies and locks the printing area, and controls the nozzle assembly on the machine table to perform base printing on the special material first. There are several digital nozzles on the nozzle assembly.

[0049] Step 2: Identify the base printing area to determine the auxiliary material dispersion area. There is a module assembly on the nozzle assembly for storing and assisting in ejecting the auxiliary materials required for the special material. There are also a water-based ink cartridge group, a white ink cartridge, and a curing agent cartridge on the nozzle assembly. The water-based ink cartridge group, the white ink cartridge, the curing agent cartridge, and the module assembly move synchronously with the digital nozzles. The water-based ink group includes water-based inks of various colors. The auxiliary materials are powdery materials with visual effects, sequins, particulate matter, or flocculent substances, and the aperture of the corresponding digital nozzle is at least larger than the size of the auxiliary material.

[0050] Step 3: Control the module assembly to evenly eject the auxiliary materials. After the printing equipment outputs the water-based ink, the auxiliary materials are evenly ejected at intervals of 0.1 - 0.5 s to form the spray-painted pattern.

[0051] Step 4: Perform post-treatment by drying to ensure that the spray-painted pattern is fixed.

[0052] The powdery material with visual effects includes fluorescent powder, bright powder, and reflective powder. The particulate matter includes foamed particles and TPU particles. The spray painting and printing method is used for printing on textiles, fiberboards, and leather. The textiles include woven fabrics and knitted fabrics.

[0053] Example 2

[0054] This embodiment provides a fabric which adopts the spray printing method in Embodiment 1. Its structural feature lies in that any auxiliary materials are arranged on the fabric structure, such as: powder substances (fluorescent powder, bright powder, reflective powder, etc.), sequins (fluorescent sequins, reflective sequins, etc.), particulate matters (foaming balls, TPU balls, etc.), flocculent substances (yarn flocculent substances, etc.).

[0055] Taking the offset printing equipment as an example of traditional printing equipment, the corresponding powder (such as fluorescent powder) is added to the offset printing ink tank and stirred. Only after the stirring is uniform can the offset printing be started. If the stirring is not uniform, the product effect will decline. Most of the processing methods in the prior art adopt the post-process treatment method. Taking the offset-printed shoe upper as an example, if sequins need to be set on the offset-printed shoe upper, special equipment is required to add sequins in the original offset-printed shoe upper process, and then it is shaped. In the auxiliary material adding process of the present invention, after the product is output by the printing equipment, the product already has the auxiliary materials and no post-process treatment is required anymore. The preparation efficiency is improved and the production cost is reduced.

[0056] Taking the application to the shoe upper as an example, the preparation method of the traditional shoe upper is: first, the base is woven by a weaving equipment, and then heat transfer printing is carried out on the base by a hot pressing equipment. The increase in processes reduces the preparation efficiency. Compared with the traditional process, the spray printing method of the present invention, when applied to the shoe upper, is not limited to the base and can be spray-printed on textiles and leather. The printing equipment uses inkjet drawing, and with the addition of auxiliary materials in the printing method, the patterns, textures, and styles are more colorful, the pattern limitations are smaller, and the artistic sense is stronger.

[0057] Embodiment 3

[0058] This embodiment applies the spray printing method of special materials in Embodiment 1 and the fabric in Embodiment 2 to fields such as shoe materials, clothing, and luggage. Compared with the traditional process, the preparation time is shortened, the preparation efficiency is improved, and the finished product is more creative and artistic.

[0059] Among them, the traditional process means: after the fabric is made, the auxiliary materials are set through another equipment.

[0060] Embodiment 4

[0061] On the basis of the above embodiments, multi-color water-based ink is combined and applied to further improve the spray printing method, including the following features:

[0062] Multi-color water-based ink combination: A water-based ink cartridge group of multiple colors is arranged on the nozzle assembly, including basic colors such as red, yellow, blue, etc. By reasonably controlling the output of these water-based inks, more colorful spray printing is realized.

[0063] Color mixing control: By controlling the mixing ratio of water-based inks of different colors, new colors are modulated to enable adjacent colors to smoothly transition in the pattern, forming a finer pattern effect.

[0064] Increase the flexibility of color selection: The printhead assembly can replace the water-based ink cartridge as needed, making the printed patterns more diverse.

[0072] Automation control system: Introduce an automation control system to realize the automatic positioning, auxiliary material spraying, drying and other steps of the printing equipment, reducing manual intervention.

[0073] Production line integration: Integrate the inkjet printing method into the production line, and achieve seamless connection with other production links (such as cutting, sewing, etc.), improving the overall production efficiency.

[0074] Intelligent production scheduling: Use intelligent algorithms to schedule the production progress, realize the reasonable allocation of production tasks, and maximize the utilization rate of the production line.
