摘　　要：为提高拒水拒油复合墙布底层面料与面层面料的剥离强度及降低生产成本,采用喷涂技术将三防助剂施加于涤纶起绒面料表面,使面料两面具备非对称润湿性,探讨制备工艺参数对涤纶面料拒水拒油性及基布剥离牢度的影响,并分析非对称润湿性涤纶起绒面料作为复合墙布面料应用的优势。结果表明:当三防助剂质量分数8%,喷浆量70 g/m^(2),焙烘温度160℃,焙烘时间60 s,可以使涤纶起绒面料两面具备显著的非对称润湿特效;在达到正面相同的拒水拒油等级时,织物非对称润湿法比传统浸轧三防剂法可降低2.1倍的带液率,其剥离牢度是传统浸轧三防剂法的3.7倍。非对称润湿性复合墙布面料制备成本低,正面拒水拒油性能良好,与织物复合后的剥离牢度高,具有广阔的应用前景。In order to improve the peeling strength of underlying fabric and surface fabric of water and oil repellent composite wall coverings and reduce production cost,spraying technology was adopted to apply three-prevention additive to the surface of polyester fleece fabric,so that both sides of the fabric can have asy mmetric wettability.The impact of preparation parameters on the water and oil repellency of polyester fabrics and the peeling strength of base fabric were discussed,and the advantages of polyester fleece fabric with asy mmetric wettability as composite wall coverings were analyzed.The results indicate that when the mass fraction of three-prevention additive is 8%,the amount of spray is 70 g/m^(2),the baking temperature is 160℃,and the baking time is 60 s,both sides of polyester fleece fabric show significant asy mmetric wettability.When reaching the same level of water and oil repellency as the obverse side,the fabric asy mmetric wetting method can lower the liquid entrainment rate by 2.1 times compared with the traditional three-prevention additive padding method,and the peeling strength of the fabric is 3.7 times that of the traditional three-prevention additive padding method.Composite wall coverings with asy mmetric wettability involved in this study has a low preparation cost,good water and oil repellency on the obverse side and high peeling strength after they are compounded with fabrics.They have a broad application prospect.
