Fuya Denim - Professional Wholesale Denim Fabric And Jeans Fabric Supplier In China
With the continuous development of printing and dyeing technology, the style of denim fabric is constantly changing. Printed denim fabric is widely favored by consumers with three-dimensional and realistic style. Looking into its printing processing technology, at present, the denim industry mainly involves discharge printing and transfer printing.Discharge printing is to print discharge agent on the fabric dyed with background color to turn the printing pattern into white, which is called discharge printing; Making the printing pattern appear a lighter background color is called half pulling; Making the printing pattern show other colors is called color pulling. Discharge printing for printed fabrics with a large area of background color, it can print excellent bright and complex patterns, and the pattern outline is clear and full of three-dimensional feeling.Transfer printing is to first print the dye on the transfer printing paper, and then transfer the dye in the pattern to the textile and fix it to form the pattern. Transfer printing can be divided into heat transfer printing and cold transfer printing according to different transfer methods.
Heat transfer printing refers to the printing process of transferring the printing pattern from the printing paper printed with disperse dye pattern to the fabric under certain temperature and pressure, especially suitable for polyester fabric.Cold transfer printing refers to the printing process in which the printing paper with reactive dye pattern is transferred to the cotton cloth soaked with alkali solution under certain pressure, and then the color is fixed by cold stacking.Because the cold transfer printing technology can directly use the transfer printing paper at room temperature, the popular elements can be transferred to denim fabrics through the high-precision cold transfer printing machine, which can obtain the effects of bright colors, clear layers and exquisite patterns. At the same time, cold transfer printing has attracted the attention of consumers and people in the industry because of its shorter process flow, more energy saving and environmental protection.
However, most denim fabric manufacturers do not have cold transfer printing equipment, and the transfer paper plate making cost is expensive, and the transfer paper is difficult to recycle after use, so the production cost of fabric is high. In addition, the organizational structure of denim fabric is rich and changeable, and the fiber raw materials and organizational design of many fabrics are not suitable for cold transfer printing technology, so it also restricts the application of this technology in denim production.
