Description

Technical Field

[0001] The invention relates to the technical field of textile materials, in particular to antibacterial and deodorizing polar fleece heating fabric and a preparation method thereof. Background Art

[0002] As people's living standards continue to improve, consumers have higher and higher functional requirements for clothing, especially in winter, when warmth and comfort become the main considerations for people to buy clothing. Traditional polyester polar fleece fabric provides good warmth retention through its fiber structure and high-density fleece layer. The fluffy structure of the polar fleece can form an air barrier, effectively isolating the cold air from the outside and maintaining body temperature. In addition, polyester polar fleece fabric is soft to the touch and comfortable to wear. Its fine fleece layer can provide a soft touch and is skin-friendly, making it suitable for making close-fitting clothing such as thermal underwear, pajamas and jackets.

[0003] However, although traditional polyester polar fleece fabrics have a certain warmth retention effect, they are prone to produce odor after long-term use and do not have antibacterial properties, which cannot meet the diverse needs of modern consumers. First, traditional polyester polar fleece fabrics mainly rely on the structure and density of the fiber to provide warmth, but in extremely cold environments, their warmth retention performance is difficult to meet demand; although there are solutions in the prior art to improve warmth retention performance by adding far-infrared ceramic powder, the effect is limited, and it is difficult to maintain a long-term warmth retention effect in actual use; Secondly, some existing technologies achieve antibacterial effects by adding antibacterial agents to polyester fibers or using antibacterial fibers, but these antibacterial agents are easily ineffective after multiple washings, and the antibacterial effect is difficult to last; especially in the medical and health fields, traditional antibacterial fabrics are difficult to provide long-term and effective antibacterial protection and cannot fully protect the health of users; Furthermore, traditional deodorization technologies mainly rely on chemical agents or simple physical adsorption methods. Although these methods can reduce odor to a certain extent, they are still difficult to keep fresh after long-term wear or strenuous exercise. The existing technology lacks solutions that can continuously play a deodorization role during long-term use. Finally, in the existing technology, the warmth-keeping, antibacterial, and deodorizing functions of fabrics often exist independently, and few fabrics can possess these superior properties at the same time; even if some fabrics achieve multifunctionality by combining multiple functional materials, they are often difficult to promote and use in actual applications due to complex processes, high costs, and other issues. Summary of the invention
