| ①添加有亲水基团的单体或低聚体聚乙二醇等进行共聚，能提高纤维的吸湿率； (1) Adding hydrophilic monomers or oligomers such as polyethylene glycol to copolymerize can improve the moisture absorption of the fibers. ②添加具有抗静电性能的单体进行共聚，可以提高纤维的抗静电和抗沾污性能； (2) Adding monomers with antistatic properties to copolymerize can improve the antistatic and antifouling properties of the fibers. ③添加含磷、含卤素和锑的化合物以改善纤维耐燃烧性能； (3) Compounds containing phosphorus, halogen and antimony were added to improve the combustion resistance of the fibers. ④采用较低聚合度的聚酯纺丝以提高抗起球能力； (4) Polyester spinning with lower degree of polymerization was used to improve pilling resistance. ⑤与亲染料基团的单体（如磺酸盐等）进行共聚，以改善纤维的染色性能。经过物理变形的有各种异形涤纶、与其他高聚物复合纺丝、着色的涤纶、细旦涤纶和高收缩涤纶等。 (5) Copolymerization with dye-affinity monomers (such as sulfonates) to improve the dyeing properties shoudonghulu.07858.netbxgxianwei.37ix.com.cnmiaomubj.37ix.com.cnkangyongg.37ix.com.cnof the hengshui.71ix.cnhuanlianhulu.07858.netfibers. After physical deformation, there are various profiled polyester fibers, composite spinning with other polymers, colored polyester fibers, fine denier polyester fibers and high shrinkage polyester fibers. |
