芳纶、海藻纤维复合高隔热针织面料开发

Development of Aramid and Seaweed Fiber Knitted Composite Fabric with High Thermal Insulation Performance

海藻纤维吸湿透气性好,具有一定的抗菌性,但不耐酸碱,湿强低,纤维间抱合力差,限制了其在服用领域的应用;芳纶具有良好的机械特性和优异的隔热性能,但吸湿透气性差。文中综合考虑海藻纤维和芳纶的优异品质,辅以棉纤维进行复合纱线的纺制,开发一种具有优异隔热性能,且辅以吸湿、抗菌功能的芳纶、海藻纤维复合功能针织面料,并测试纱线力学性能、吸湿性能以及织物的导热性能。结果表明,芳纶、海藻纤维复合针织面料具有良好的力学性能、吸湿透气性,以及高度隔热的特点,适用于消防员服用针织面料的开发。

Seaweed fiber has good moisture absorption and permeability and certain antibacterial properties,but it is not acid-base resistant with low wet strength and poor cohesion between fibers,which limits its application in the field of apparel.Aramid fiber has good mechanical properties,excellent heat insulation performance,but with poor moisture absorption and permeability.In this paper,considering the excellent quality of seaweed fiber and aramid fiber,combined with cotton fiber for composite yarn spinning,a kind of aramid seaweed composite knitted fabric with excellent heat insulation performance,moisture absorption and antibacterial function is developed,and the mechanical properties,moisture absorption and thermal conductivity of the yarn are tested.The results show that the aramid and seaweed fiber knitted composite fabric has the characteristics of good mechanical properties,excellent moisture absorption and air permeability and high heat insulation performance,which is suitable for development of fabrics for firefighters.
