摘要： 以天冬氨酸、赖氨酸作为阻燃剂，采用超临界CO2技术对涤纶织物进行阻燃整理，探讨了阻燃剂用量及超临界处理的温度、压强和时间对涤纶阻燃性能的影响，并对阻燃整理后涤纶织物的力学性能和热力学性能进行了测试。结果表明：阻燃性能随着阻燃剂用量的增多及超临界处理时温度和压强的上升而升高，确定较优整理工艺是阻燃剂用量为10% o.w.f.，超临界处理条件为25 MPa、135 ℃、60 min，经天冬氨酸或赖氨酸整理后涤纶织物的损毁长度均小于10 cm，LOI值大于30%；织物的断裂强力分别提高了94 N和76 N，断裂延伸率分别提高了14.6%和15.1%，熔融焓、残余量等都出现小幅度上升，表明阻燃整理后织物的力学和热力学性能均提升，多次水洗后织物的LOI值均不低于28%。

Abstract: In this paper, aspartic acid and lysine were used as flame retardants, and the flame-retardant finishing of PET fabric was carried out by supercritical CO2 technology. The effects of flame retardant dosage, temperature, pressure, and time of supercritical treatment on the flame-retardant performance of PET fabric were discussed. The mechanical and thermodynamic properties of PET fabric after flame-retardant finishing were tested. The results showed that the flame-retardant performance increased with the increase in the amount of flame retardant and the increase in temperature and pressure during supercritical treatment. The optimal finishing process was determined as flame retardant at 10% o.w.f., with supercitical conditions of 25 MPa, 135 °C and 60 min. The char length of PET fabric after aspartic acid or lysine finishing was less than 10 cm, and the LOI value was greater than 30%. The breaking strength of the PET fabric increased by 94 N and 76 N, respectively, and the elongation at break increased by 14.6% and 15.1%, respectively. The melting enthalpy and residue increased slightly, indicating that the mechanical and thermodynamic properties of the PET fabric after flame-retardant finishing were improved. After repeated washing, the LOI values of PET fabrics can reach no less than 28%.
