Description

Technical Field

[0001] This utility model relates to the field of weft knitted fabric technology, and in particular to a unidirectional moisture-wicking weft knitted fabric. Background Technology

[0002] Knitted fabrics can be divided into two main categories based on their weaving method: weft-knitted fabrics and warp-knitted fabrics. Weft-knitted fabrics are made from yarns of natural fibers, chemical fibers, etc., using loop structures, float structures, tuck structures, transfer structures, etc., on various weft knitting circular knitting machines. The yarns are bent into loops and interlocked on the horizontal direction by the diamond arrangement of the knitting needles.

[0003] With technological advancements and improved living standards, people have increasingly higher demands for clothing. In the case of sportswear, fabrics not only need to present an aesthetically pleasing jacquard texture to meet aesthetic needs, but also require special functionalities, such as one-way moisture wicking, to ensure the wearer's comfort and experience during exercise. However, most jacquard knitted weft-knitted fabrics currently on the market lack this crucial one-way moisture wicking function. Therefore, to meet consumers' urgent need for comfort during heavy sweating during exercise, it is imperative to design and produce more knitted weft-knitted fabrics that possess both a beautiful jacquard texture and one-way moisture wicking functionality. This would fill this market gap, improve the overall performance and quality of sportswear, and meet consumers' comfort requirements when experiencing heavy sweating during exercise.

This improves the fabric's appearance while also providing excellent unidirectional moisture-wicking and quick-drying properties, meeting consumers' comfort requirements during periods of heavy sweating. When the unidirectional moisture-wicking polyester filament-woven jacquard inner layer is used as the skin-contact surface, it quickly wicks sweat to the outer layer, keeping the inner layer dry against the skin. Simultaneously, the plain weave surface of the moisture-wicking and quick-drying polyester filaments forms the outer layer, providing quick-drying functionality. Overall, the invention achieves both unidirectional moisture wicking and quick-drying effects. Attached Figure Description

[0062] (6) Fabric dyeing and finishing: The fabric obtained in step (5) is unwound, pre-shaped at low temperature, dyed in an overflow tank, opened, treated with softener, and finished with finishing agent to obtain a double-sided jacquard weft-knitted fabric with unidirectional moisture wicking and quick-drying functions. The finished weight is 115-135 g / m². The fabric has good unidirectional moisture wicking and quick-drying properties. Specific functional tests are as follows: Figure 5 .

[0063] Using a 34-inch, 24-needle weft-knitted double-sided circular knitting machine with three types of needles and 12 different diamond-shaped arrangements, unidirectional moisture-wicking polyester filaments and quick-drying polyester filaments are woven into layers: an inner layer with a jacquard mesh texture and an outer layer with a plain weave texture. This enhances the fabric's appearance while providing excellent unidirectional moisture-wicking and quick-drying properties, meeting consumers' comfort requirements during strenuous exercise when heavily sweaty. When the unidirectional moisture-wicking polyester filament-woven jacquard inner layer is used as the skin-contact surface, it quickly wicks sweat to the outer layer, keeping the inner layer dry against the skin. Simultaneously, the plain weave outer layer, woven from moisture-wicking and quick-drying polyester filaments, provides quick-drying functionality, achieving both unidirectional moisture wicking and quick-drying effects overall.
