嵌段型聚醚聚酰胺耐久亲水整理剂的应用研究

Study on application of polyamide-b-polyether copolymer for nylon's durable hydrophilic finishing

以尼龙66盐、己二酸和聚醚胺为原料,经两步熔融缩聚制备嵌段型聚醚聚酰胺耐久亲水整理剂EDP,并将其应用于锦纶织物的亲水整理。研究整理剂EDP用量、焙烘温度和焙烘时间对织物亲水性和耐水洗性能的影响,优化整理工艺条件,测定整理后锦纶织物的性能。研究结果表明:当整理剂用量为40g/L,烘焙温度为170℃,烘焙时间为50s时可获得最佳整理效果,整理后织物的毛细效应高度为3.4cm,5次水洗后毛效保留率可达82.5%。相比于市售的国外锦纶专用亲水整理剂和国内亲水氨基硅油类整理剂,经整理剂EDP整理的锦纶织物具有更为优异的亲水性和耐水洗性能。

The polyamide-b-polyether copolymer for nylon hydrophilic finishing was synthesized with melt-polycondensation by using nylon66 salt,adipic acid and polyether amine as raw materials,and it was applied for nylon hydrophilic finishing.The influences of finishing factors such as dosage of EDP,curing temperature and time on the hydrophilia and washing durability were studied.The conditions of finishing process were optimized and the performances of finished fabrics were measured.The results show that the optimal conditions of finishing process are gained under the following conditions：dosage of finishing agent40 g/L,the curing temperature 170 ℃ and time 50 srespectively.The capillary effect height of finished fabrics was 3.4 cm,and capillary effect retention rate could reach 82.5% after washing for 5 times.Compared with the fabrics finished by other commercial finishing agents,EDP-finished fabrics show better hydrophilic properties and durability.
