壳聚糖、棉混纺抗菌针织物的性能研究

Study on the Performance of Antibacterial Fabric Knitted with Chitosan/Cotton Blended Yarn

采用18 tex壳聚糖、棉混纺纱(混纺比10∶90、20∶80、30∶70)编织纬平针、衬垫和空气层组织,测试试样的耐磨性、顶破性、透气性和透湿性,并采用比浊法对试样抗菌性能进行分析。结果表明:随壳聚糖纤维含量的增加,织物耐磨性与顶破强力下降;织物组织结构对其力学性能与通透性能均有影响,空气层组织力学性能最好,纬平针组织通透性最好;织物抗菌性随壳聚糖含量增加而提高,但波动幅度不大。

Three different fabrics including weft plain, laying-in stitch and cross float interlock structure are de_veloped by using 18 tex chitosan/cotton blended yarns with different blended ratios （10∶90,20∶80,30∶70）, and the wear-resisting, bursting strength, air permeability properties are tested, as well as the antibacterial properties ana_lyzed by turbidimetry method. The results show that higher the content of chitosan is, the worse the wear-resisting properties and bursting strength will be; the structure of fabrics will have an effect on the mechanical properties and opaque properties, i.e., cross float interlock with the best mechanical properties and the weft plain with the best air permeability; the antibacterial properties will increase with chitosan content, but the difference is not significant.
