Embodiment 1

[0019] According to the preparation process of the bright light printing coated polyester cloth of the present embodiment is as follows:

[0020] (1) Carry out calendering treatment to the polyester base fabric;

[0021] (2) Carry out dry coating of polyurethane mixed solution to the base cloth after step (1), the specific process is as follows: first, coat the first polyurethane mixed solution on the polyester base cloth, and dry it at 120°C to obtain The film forms the first polyurethane coating, and the drying time is 40s. Then, the second polyurethane mixture is coated on the first polyurethane coating, and dried at 150°C to form a film to form the second polyurethane coating. The drying time is 40s; secondly, print on the second polyurethane coating with printing color film paper, the printing time is 4s, and the printing temperature is 120°C; finally, the third polyurethane mixture is coated on the printing surface of the polyester base fabric, and the Dry at 150°C to f...

Embodiment 2

[0024] According to the preparation process of the bright light printing coated polyester cloth of the present embodiment is as follows:

[0025] (1) Carry out calendering treatment to the polyester base fabric;

[0026] (2) Carry out dry coating of polyurethane mixed solution to the base cloth after step (1), the specific process is as follows: first, coat the first polyurethane mixed solution on the polyester base cloth, and dry it at 130°C to obtain The film forms the first polyurethane coating, and the drying time is 50s. Then, the second polyurethane mixture is coated on the first polyurethane coating, and dried at 155°C to form a film to form the second polyurethane coating. The drying time is 50s; secondly, print on the second polyurethane coating with printing color film paper, the printing time is 6s, and the printing temperature is 120°C; finally, the third polyurethane mixture is coated on the printing surface of the polyester base fabric, and the Dry at 155°C to f...

Embodiment 3

[0029] According to the preparation process of the bright light printing coated polyester cloth of the present embodiment is as follows:

[0030] (1) Carry out calendering treatment to the polyester base fabric;

[0031] (2) Carry out dry coating of polyurethane mixed solution to the base cloth after step (1), the specific process is as follows: first, coat the first polyurethane mixed solution on the polyester base cloth, and dry it at 130°C to obtain The film forms the first polyurethane coating, and the drying time is 55s. Then, the second polyurethane mixture is coated on the first polyurethane coating, and dried at 160°C to form a film to form the second polyurethane coating. The drying time is 55s; secondly, print on the second polyurethane coating with printing color film paper, the printing time is 8s, and the printing temperature is 130°C; finally, the third polyurethane mixture is coated on the printing surface of the polyester base fabric, and the Dry at 155°C to f...

Abstract

The invention relates to a process for preparing a bright printing coating polyester fabric, which comprises the following steps of: firstly, performing calendaring treatment on a polyester base fabric and coating two layers of polyurethane membranes on the surface of the basic fabric in turn; secondly, printing textures on the coating face of the fabric; thirdly, coating a third layer of polyurethane membrane on printing face; and finally, executing processes of washing the fabric with water and the like, detecting an obtained product and storing the qualified product in a warehouse. In the invention, the coating fabric has the third layer of polyurethane membrane after texture printing to prevent the printing face of the fabric from corrosion and interference from the external environment, so that the color fastness of the printed fabric is effectively improved and the high transparency and glossiness of the polyurethane membranes ensure that the color and luster of the printing coating fabric are brighter and more long-lasting after the polyurethane membranes are tightly adhered to the printing face. The process can well meet the appearance requirements of the market on the high color fastness and the bright and long-lasting color and luster of the coating fabric.

Description

technical field [0001] The invention relates to a preparation process of polyurethane (PU) coated polyester cloth. Background technique [0002] Coated fabric is one of the most rapidly developing new textile varieties in recent years. It is a product obtained after coating and finishing ordinary fabrics. The so-called coating finishing is to uniformly coat one or more layers of polymers on the surface of the fabric to form a film on the surface of the fabric, endow the fabric with certain functions, and even change the appearance and style of the fabric. With the advancement of science and technology and the continuous improvement of people's quality of life, people have higher and higher requirements for the appearance of daily fabrics such as clothing worn, curtains and tablecloths used for interior decoration, and bags carried when going out. However, common printed fabrics on the market generally have poor color fastness and insufficient bright color, which is difficul...
