Description

Technical Field

[0001] The present invention relates to a dimensionally stable high-count double-sided lattice knitted shirt fabric and its production process, belonging to the field of textile technology. Background Art

[0002] Knitted fabrics have good elasticity and breathability, excellent wearing comfort, flexible production processes, and high production efficiency. However, their overall structure is loose, and their dimensional stability, stiffness, and pilling resistance are relatively poor. Therefore, high-count double-sided lattice jacquard knitted fabrics for high-dimensionally stable shirts still have great development potential.

[0003] Chinese Patent CN302226216S discloses a lattice pattern: Name of the design product: Twill lattice fabric. Use of the design product: Clothing, furniture decoration. Key points of the design: The squares are filled with twills. This patent focuses on the appearance pattern of the lattice fabric and does not involve specific production processes, so its dimensional stability cannot be evaluated.

[0004] Chinese Patent CN117026483A discloses a jacquard knitted fabric and its processing method. The raw materials of this fabric consist of polyester and tencel. Its processing method includes: weaving the fabric embryo and combining the needle cylinder cams to arrange the knitting in a full loop; this patent adopts a suitable production process to achieve the stiffness and appearance of woven fabrics, so its tissue structure is tight, dimensionally stable, and has poor breathability. It does not highlight the excellent breathability and recovery performance of knitted fabrics and is not suitable for making shirt fabrics.

[0005] Chinese Patent CN115852577A discloses a preparation method of a black and white lattice jacquard fabric. It can manufacture a black and white lattice jacquard flannel fabric with a large pattern repeat and strong three-dimensional sense. This patent focuses on the black and white lattice jacquard fabric, which is woven by a warp knitting machine. Although the comfort of warp knitted fabrics is stronger than that of woven fabrics, their lateral elongation, elasticity, and softness are not as good as those of weft knitted fabrics.
