The present invention relates to a Calico and the Method for manufacturing coloured fabrics, the method is based on printing a pattern on a waterproof and breathable membrane by using digital ink-jet printing technology, and laminating the membrane together with a colorless and patternless fabric in order to form a calico.
In such screen printing technique, you need to have a screen printing plate, and it is made by wooden or metal frame which has the thin mesh nylon and polyester or metal silk fabric tight on it, and coating an opacity non porous membrane on the fabric of the screen printing plate, and remove such opacity membrane on the pattern spot, with only the thin mesh is left on the pattern spot, this spot is where you do the printing. In the most of the case, the fabric of the screen printing plate is coating with an photosensitivity membrane, and removing the membrane on the pattern spot by sensitometry to show the pattern, place the screen printing plate on the fabric which is ready to be print, and pour the print paste inside the printing frame, so the scraper can make the print paste pass through the thin mesh.
There are three common techniques for screen printing: flat screen printing, rotary screen printing, and roller printing.
The flat screen printing technique is to print the pattern by using flat screen printing machine, the conveyor on the flat screen printing machine send the fabric to the screen printing plate, and the fabric stop under the screen printing plate, the scraper on the screen printing machine scrap the pattern on the fabric and move to the next printing frame.
The rotary screen printing technique is using continuous process. The conveyor send the screen printing plate to the rotary cylinder which is in constant motion, and print the pattern on the fabric.
The roller printing technique is also using continuous process, it is more like printing an news paper, the pattern on the copper printing roller roll over the fabric and print the pattern on the fabric.
Even though all the above techniques can achieve the objective of printing pattern on the fabric, but they all have the complexity work of plate making, it is not only takes a lot time to making the plate and the cost is also very high and a big working space is also necessary. According to the statistics, in the last 10 years, the market of calico is decrease. The main reason is that the pace of the modern society is changing fast, same pattern can not be use over and over again, therefore, the screen printing which have the long manufacturing hour and high cost is no longer satisfies the manufacture of calico today.
Also, the color can easily goes off when you print the pattern straight on the fabric.
These are the problem of manufacture of calico in traditional way.
In view of the above drawbacks, an objective of the present invention is to provide a Calico and the Method for manufacturing coloured fabrics which can strengthening the color fastness to washing, color fastness to water, color fastness to light, and color fastness to crocking of the calico, and reducing the manufacturing procedure and cost.
