Description

Technical Field

[0001] The utility model relates to a cotton-acrylic blended yarn and a knitted fabric, belonging to the technical field of textile fabrics. Background Art

[0002] With climate change and improved living standards, people's demand for winter warm clothing is gradually increasing. Traditional thermal insulation materials have certain limitations in terms of hygroscopicity and heat generation performance, so it is necessary to carry out research on new high-performance thermal insulation materials. And with the development of society, people's requirements for fabrics are not only good in terms of warmth but also light and thin. Knitted fabrics are widely welcomed by consumers because of their soft texture, high elasticity and comfortable wearing. People pay more and more attention to the research and development of knitted fabrics. In the process of research and development of new knitted fabrics, some special properties are inevitably involved, such as antibacterial, flame retardant, warm or UV protection. Functional knitted fabrics have now been widely used in various fields. In order to meet people's needs, the development and application market of new fibers is becoming more and more popular. Among them, hygroscopic heat-generating fibers are a new type of fiber that has developed rapidly in recent years. Fibers generate heat by absorbing moisture to keep the human body in a comfortable state. This is a new technology product. Using this feature, hygroscopic heat-generating fibers can keep the temperature in the microclimate between the human body and clothing basically constant, so that the human body is always in a comfortable temperature range, thereby preventing heat stress and meeting the needs of human comfort under the conditions of heating or cooling of the external environment. How to prepare a cotton-acrylic blended yarn and knitted fabric with heating effect has become a problem to be solved. Utility Model Content
