Description

Technical Field

[0001] The present invention relates to the technical field of fabric dyeing and finishing, and more specifically, to a dyeing and finishing process for high-count ultra-thin printed fabrics. Background Art

[0002] High-count ultra-thin fabrics are widely favored in the textile printing and dyeing field due to their lightness, softness, and unique texture, and exhibit broad application prospects. Such fabrics have excellent comfort and drapability and are often used in making high-end clothing, accessories, and household items, etc. Especially in delicate products such as printed scarves and museum silk scarves, they have been greatly applied.

[0003] However, when printing and dyeing high-count ultra-thin fabrics, their thin structural characteristics bring many technical problems. Traditional printing processes are difficult to precisely control the penetration and adhesion of printing pastes, easily resulting in blurred printed patterns, uneven color distribution, and even paste leakage to the back of the fabric, causing obvious color differences between the front and back sides, affecting the appearance quality and overall quality of the product. In addition, to ensure the clarity and color fastness of printed patterns, water-soluble substances are usually used as auxiliary materials, such as water-soluble linings. However, in the subsequent treatment stage, if these water-soluble substances are not completely dissolved and removed, they will leave marks on the fabric, making the hand feel rough and not soft, destroying the overall beauty of the printed pattern, and reducing the product grade.

[0004] Regarding the problems in the related art, no effective solutions have been proposed yet. Summary of the Invention
