Hybrid Printing and Dyeing Method for Producing Double-Sided Patterned Fabrics

Abstract

The invention relates to a hybrid production method that enables the creation of patterns on both surfaces of the fabric through a combination of rotary printing and reactive dyeing. Thanks to special printing pastes and surface protective chemicals, the printed areas remain lighter in color or closer to the print color after dyeing, thus achieving a double-sided pattern effect.

Description

Hybrid Printing and Dyeing Method for Producing Double-Sided Patterned Fabrics TECHNICAL FIELD The invention enables double-sided patterning of fabrics used in the textile industry. It relates to a production method based on combinations of hybrid printing and flat dyeing. Specifically, Printed patterns in color or colorless on the fabric surface, and uncolored areas outside the pattern. areas in different colors or different shades of the same color after reactive dyeing An innovative process is presented that enables its formation. PREVIOUS TECHNIQUE In the textile industry, the processes of creating patterns on the fabric surface are done through traditional printing and digital printing. This is achieved through printing methods. In the current state of the technique, printing and dyeing... The processes are implemented independently of each other, and the combined use of these two processes It involves various technical challenges. The main ones encountered in the known state of the art are... The problems are detailed below. In the known state of the art, etching is the printing paste applied after painting. It is used. In the known state of the art, printing is applied after painting. abrasive floor paint that is susceptible to abrasive chemicals in the paste and Appropriate dye groups are required for coloring. In etching printing... Additionally, quality issues arise due to wear and tear on the fabric structure. Specifically... The use of prohibited etching chemicals is also a concern in etching printing methods. This also occurs. In addition, the abrasive chemicals used affect working comfort. It is known to have a foul odor. In another known instance of the technique, in rotary printing methods, the pattern is only It is applied to the front surface of the fabric. In the known state of the technique, the front of the fabric... A distinct pattern appears on the back of the fabric after printing is applied to its surface. The formation cannot be achieved. The transfer of the pattern to the back is usually not as clear as desired. This may not be possible. This situation leads to production limitations in applications where a double-sided pattern is desired. This is why a clear and consistent pattern is obtained on both the front and back surfaces of the fabric. Additional processes are required to achieve this, which makes the production process more costly. It brings. 1 The fabric, on which a pattern is created using the rotary printing method, is subjected to a reactive dyeing process. the clarity of the pattern in the printed areas that transfer to the back of the fabric when held is decreasing or disappearing completely. The main reason for this is the back of the fabric. The printed areas on the face are a partial barrier of the reactive dye printing paste. As a result of the application, the probability of bonding by approaching the fibers increases, and the surrounding environment... It should approximate the color tone of the unprinted areas. Especially dark backgrounds. In their paintings, the patterns created by printing disappear completely or very little. This is becoming apparent. This situation is bilateral in the known state of the technique. The design does not meet the acceptance criteria when requested. Traditional printing pastes are formulated to be compatible with the reactive dyeing process. This discrepancy occurred when a double-sided pattern was requested for printing and dyeing. In production processes where these processes are used together, it leads to unexpected results. It opens up. When printed areas show high absorption in the reactive dyeing bath. The clarity of the pattern decreases; otherwise, the paint will not adhere to the printed areas. This causes the pattern to appear incomplete or irregular. In conclusion, applying the printing and dyeing processes sequentially results in the desired design. This makes it difficult to obtain. In the current state of the art, fabrics and patterns produced using traditional methods Significant inconsistencies in quality are observed. Post-painting etching printing. In terms of working conditions, cost, and fabric quality in their applications... There is no sustainability. In pigment printing post-dyeing applications, the front of the fabric... The pattern that is prominent on the surface is formed completely randomly on the back surface, and It is generally not possible to achieve a homogeneous appearance. The pattern is barely visible on the reverse side. This makes it difficult for both sides of the fabric to be usable. Also, different The quality of the pattern varies depending on the fabric type and the printing paste used. Depending on factors such as the formula, fabric structure, and dyeing process, different results can be obtained. This makes it difficult to ensure consistency in production and affects the customer. This makes it difficult for their expectations to be met. In the current state of the art, it is possible to obtain a double-sided pattern using existing methods. Additional printing processes are required. For example, some manufacturers print separately on both sides of the fabric. They are trying to create a double-sided design by printing separately. In this case, the first print Then, transitions occur to the back of the fabric, and the patterns match in the second print. The difficulty of bringing 35 in is emerging. And this method leads to both a waste of time and... 2 This leads to increased costs due to poor quality. Extra processes affect the production process. It prolongs the process and also increases chemical and water consumption. In addition, multiple Applying this treatment causes the fabric to deteriorate, reducing its mechanical strength. This can cause a decrease. These additional costs in production and quality control problems, This reveals the need for a more efficient and economical solution in the textile industry. Due to the aforementioned problems in the known state of the art, fabrics both Creating the desired patterns on both the front and back surfaces is difficult, costly, and requires quality control. It is inconsistent in this respect. In the textile industry, it creates double-sided patterns through printing and dyeing. innovative processes that make processes more harmonious and the production process more efficient The need for a sustainable method has arisen.
