[0001] This invention relates to the field of knitted fabric technology, and in particular to a double-layer effect carbon dioxide trapping unidirectional moisture-wicking weft-knitted fabric and its production method. Background Technology

[0002] Currently, knitted fabrics on the market still have certain limitations in terms of functionality, especially in the absence of mature products that simultaneously possess multiple properties such as double-layer structure, environmentally friendly carbon capture, one-way moisture wicking, and quick-drying. Traditional fabrics often only achieve a single function, such as only possessing moisture absorption or only possessing water repellency, which is difficult to meet the comprehensive needs of modern sportswear and casual wear for comfort, functionality, and environmental protection. In addition, the production process of existing fabrics has a significant negative impact on the environment, and there is a lack of carbon dioxide recycling. Therefore, there is an urgent need to develop a new type of knitted fabric that combines aesthetics, functionality, and environmental protection.

[0003] In view of this, the inventor, in order to address the numerous shortcomings and inconveniences caused by the imperfections in the aforementioned fabrics and their production methods, has conceived and actively researched and experimented with improvements to develop this invention.

This fabric not only has a special double-sided double-layer appearance and color effect and moisture-wicking and quick-drying function, but also has a unidirectional moisture-wicking function. The production method preferably involves collecting carbon dioxide from the air, then chemically reacting it into ethylene glycol, and then polymerizing it with PTA to form PET polyester filaments, fluorine-free water-repellent polyester filaments, and modal yarns through a special finishing process.

Needle B (medium heel needle) on the needle tray corresponds to forming loops, while needle A (high heel needle) on the needle tray is not working. For needle trays 2, 5, 7, 9, 11, 13, 15, 17, 19, 21, and 23, needle A (high heel needle) and needle B (medium heel needle) correspond to forming loops, while needles A (high heel needle), B (medium heel needle), and C (low heel needle) on the syringe are not working. For syringes 3, 6, 8, 10, 12, 14, 16, 18, 20, 22, and 24, needles A (high heel needle), B (medium heel needle), and C (low heel needle) correspond to forming loops, while needles A (high heel needle) and B (medium heel needle) on the needle tray are not working.
