DETAILED DESCRIPTION

[0021] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figure 2~Figure 9 As shown, this embodiment proposes a water-saving printing and dyeing method for fabrics, and the specific steps are as follows: S1: First immerse the fabric to be printed and dyed in warm water at 30℃~35℃, then add detergent to the warm water, wash the fabric, and then rinse the fabric with clean water. Using warm water at 30℃~35℃ for pretreatment can effectively remove grease and dirt on the surface of the fabric, while avoiding damage to the fiber due to excessive temperature. The temperature range of warm water can both dissolve and remove dirt and protect the structure of the fabric. The rinsing step after washing is to remove the residue of the detergent to ensure that the fabric will not be interfered with by the detergent ingredients during the printing and dyeing process.

[0023] S2: Immerse the fabric obtained in S1 in a bleaching agent mixed with water at a ratio of 1:10 for 15 minutes to 1 hour, and then rinse the fabric with clean water. The use of the bleaching agent can evenly remove the original color on the fabric and make it the basic color for dyeing, thereby ensuring the consistency of the dyeing effect.

[0024] S3: The fabric obtained in S2 is immersed in the setting liquid, and then the fabric is sequentially introduced into a dryer and a calender for drying and flattening. The setting liquid used in this embodiment is preferably AkzoNobel Dyno®. The setting liquid helps maintain the shape and feel of the fabric, the dryer removes moisture and fixes the setting liquid, and the calender makes the fabric smoother. This series of treatments not only improves the appearance quality and durability of the fabric, but also enhances the wearing experience of the user.

[0025] S4: Fix the fabrics obtained in S3 on the material transporting member 4 on the printing and dyeing device, start the conveyor belt 25, perform one printing and dyeing on the fabrics, and then start the transmission chain 61 to replace the screen printing screen 72, and perform multiple printing and dyeing on the fabrics. This embodiment replaces the design of multiple printing and dyeing in turn in the prior art, increases the printing and dyeing time of a single screen printing screen 72, and can effectively alleviate the solidification of the dye.

[0026] S5: The fabric is taken off the material transporting member 4 and stored to complete the printing and dyeing process.

[0027] The printing and dyeing device in the above step S4 includes a fixed frame 1, and a transport structure is arranged on the fixed frame 1 for cyclically transporting fabrics.

This design is used to install and fix the first limiting plate 641, the second limiting plate 642 and the third limiting plate 643. In this embodiment, the first sliding groove 62 and the second sliding groove 63 are the same shape as the transmission chain 61, which is convenient for limiting the parallel member 66 and preventing the parallel member 66 from rotating.

In this embodiment, the second screw rod 941 and the second sliding rod 942 are both arranged along the Y-axis direction.

[0033] The transport structure in this example includes a conveyor belt 25, a first transmission roller 21, a second transmission roller 22, a third transmission roller 23 and a fourth transmission roller 24 are rotatably arranged on a fixed frame 1, and the conveyor belt 25 is connected to the first transmission roller 21, the second transmission roller 22, the third transmission roller 23 and the fourth transmission roller 24 at the same time. The material transport guide rail 3 is fixedly arranged on the fixed frame 1, and the cross section of the material transport guide rail 3 is a "T"-shaped structure, which is used to prevent the material transport member 4 from slipping and deviating, and the material transport member 4 is detached from the material transport guide rail 3. The material transport member 4 is slidably arranged on the material transport guide rail 3, and the material transport member 4 is fixedly connected to the conveyor belt 25. The material transport guide rail 3 used in this embodiment is an annular structure.
