Problems solved by technology

[0002] The existing imitation leather fabric is coated with an imitation leather layer on the surface of the base fabric. Because of the limitation of the coating process, the imitation leather layer covers the surface of the base fabric in an all-round way. Poor performance, easy to cause discomfort after wearing for a long time
In addition, the existing imitation leather raw materials are mainly solvent-based, with high VOC content, and a large amount of VOC emissions in the production process, which seriously pollutes the environment

Abstract

The invention provides air-permeable imitation leather printed fabric and a production process thereof. The air-permeable imitation leather printed fabric comprises base cloth, wherein a plurality of imitation leather pattern blocks arranged at regular intervals are adhered to the surface of the base cloth. The production process comprises the following steps: (1) surface pre-processing for tidying the surface of the base cloth and enabling the base cloth to be clean and flat; (2) intaglio printing, wherein imitation leather size suitable for the intaglio printing is prefabricated and printed on the surface of the base cloth through the intaglio printing process so as to enable the imitation leather pattern blocks arranged at regular intervals to be formed on the surface of the base cloth; (3) drying, wherein the imitation leather pattern blocks on the surface of the base cloth are dried to have certain moisture content; and (4) film formation, wherein a heating roller is adopted to roll and press the imitation leather pattern blocks on the surface of the base cloth and enable the surfaces of the imitation leather pattern blocks to be smooth and flat and have strong leather texture, and the imitation leather pattern blocks arranged at regular intervals enable the imitation leather printed fabric to have high-end texture of imitation leather fabric and good moisture absorption and air permeability.

Description

technical field [0001] The invention relates to the field of imitation leather fabrics, in particular to a breathable imitation leather printed fabric and a production process thereof. Background technique [0002] The existing imitation leather fabric is coated with an imitation leather layer on the surface of the base fabric. Because of the limitation of the coating process, the imitation leather layer covers the surface of the base fabric in an all-round way. The performance is poor, and it is easy to cause discomfort after wearing for a long time. In addition, the existing raw materials of imitation leather are mainly solvent-based, with high VOC content, and a large amount of VOC is emitted during the production process, which seriously pollutes the environment. Contents of the invention [0003] The object of the present invention is to provide a breathable imitation leather printed fabric with good moisture absorption and air permeability to address the deficiencie...
