摘要：

为提升生物基聚对苯二甲酸丙二醇酯(PTT)织物的功能性且满足节能减排生态染整需求,采用泡沫整理技术对生物基PTT织物进行阻燃与三防一步法整理。通过响应面实验设计和优化法,分析了阻燃剂和三防整理剂质量浓度、带液率以及焙烘温度等对整理效果的影响,得到最佳整理工艺:阻燃剂和三防整理剂质量浓度分别为390、43 g/L,带液率为42%,141 ℃下焙烘1 min。研究结果表明:在最佳工艺条件下整理的PTT织物具有优异的阻燃性能和良好的三防效果,其阻燃等级达到国标B1标准,水相和油相接触角分别达到145.6°和129.2°;经20次水洗和50次摩擦后织物仍保持良好的阻燃和三防效果。实验研究的泡沫多功能整理方法为生物基纤维材料绿色清洁生产提供了有效途径。

Abstract:

In order to improve the functionality of bio-based polytrimethylene terephthalate (PTT) fabrics and meet the needs of energy saving and emission reduction for ecological dyeing and finishing, foam finishing technology are used to treat bio-based PTT fabrics for flame-retardancy and three-proof one-step finishing. Using the responsive surface experimental design and optimization method, the effects of the concentration of the flame retardant and the three-proof finishing agent, liquid carrying rate and the baking temperature on the finishing effect were analyzed. The optimal finishing process was as follows: the concentration of flame retardant and three-proof finishing agent are 390 and 43 g/L respectively, the liquid carrying rate is 42%, and baking is performed at 141 ℃ for 1 min. The research results show that the PTT fabrics finished under the optimal technological conditions have excellent flame retardant properties and good three-proof effects. The flame retardant grade reaches the national B1 standard, and the contact angles of the water phase and the oil phase reach 145.6° and 129.2°, respectively. In addition, after 20 washings and 50 rubs, the fabric still maintains good flame retardant and three-proof effects. The experimentally researched foam multifunctional finishing method provides an effective way to improve the green and clean production of bio-based fiber materials.
