Description

Technical Field

[0001] The utility model belongs to the technical field of household textile fabrics, and specifically relates to a wide-width soft, warm and antibacterial fabric containing wormwood-modified polyester filaments. Background Art

[0002] Knitted velvet fabric is widely used in autumn and winter clothing such as thermal underwear and T-shirts due to its fluffy feel, warmth retention, slight elasticity and skin-friendly fit. The wide application of velvet technology in the field of intimate clothing has promoted the expansion of consumer demand for soft, warm and fit knitted bedding. How to apply velvet technology to home textile bedding to upgrade the touch experience has become the focus of research and development personnel. Due to the scarcity of knitted wide-width weaving machines and the fact that wide-width shearing equipment has not yet been widely used, there is still a problem of insufficient production conditions for wide-width knitted velvet technology fabrics.

[0003] At present, the wide-width all-polyester velvet fabrics on the market have poor elasticity and extensibility. Although the fabric has plump pile, it is not delicate and soft, and the fabric style is rough. Moreover, the dense pile will breed bacteria in the warm and humid sleeping microenvironment, which is harmful to human health.

[0004] As a herbaceous plant of the genus Artemisia in the Asteraceae family, mugwort is rich in flavonoids, volatile oils, alkaloids, polysaccharides, terpene aromatics and other ingredients. It has the effects of warming the meridians, dispelling dampness and cold, and warming the qi and blood. It has a long history of application in traditional medicine. Modern medicine shows that mugwort ingredients have antibacterial and anti-mite, anti-inflammatory, and antioxidant effects. Adding mugwort extract to polyester filaments can give the filaments the effects of antibacterial and anti-mite, and cold-repelling and warming. Utility Model Content
