Problems solved by technology

[0003] Existing polyester knitted fabrics are often used as outdoor products such as tents. The color-fixing agent added when printing polyester knitted fabrics is a high-grade fatty acid salt. Although the fastness of this color-fixing agent is improved in a hot water environment, but Its own light fastness is low, resulting in the color printed on the tent is easy to fade due to the natural environment of wind and sun

Abstract

The invention discloses a printing process of a polyester knitted fabric and relates to the technical field of fabric dyeing and finishing. The process comprises the following steps: pre-treating, pre-sizing; printing, steaming, washing and sizing a preselected polyester knitted fabric; and adding a color fixator triethylene tetramine during washing. Through the six steps, the pattern printed on the polyester knitted fabric is high in color fastness and lasts longer in a natural environment.

Description

Technical field [0001] The invention relates to the technical field of fabric dyeing and finishing, more specifically, it relates to a printing process of polyester knitted fabric. Background technique [0002] Polyester knitted fabric is a kind of chemical fiber garment fabric used in daily life. Its biggest advantage is that it has good wrinkle resistance and shape retention, so it is suitable for outdoor products such as outerwear, various bags and tents. [0003] The existing polyester knitted fabrics are often used as outdoor products such as tents. The fixing agent added when printing on polyester knitted fabrics is higher fatty acid salts. Although this fixing agent has improved fastness in hot water, Its own light fastness is low, causing the colors printed on the tent to fade easily due to the natural environment of wind and sun. Summary of the invention [0004] The purpose of the present invention is to provide a printing process for polyester knitted fabrics. In the tr...
