摘要：

为提高聚酯/聚酰胺6(PET/PA6)中空超细纤维合成革基布的透湿性、柔软性,将聚丙烯腈(PAN)纳米纤维与PET/PA6超细纤维混合,通过水刺固网的方法制备出PAN-PET/PA6微/纳米超细纤维合成革基布并进行碱处理,分析了PAN纳米纤维质量分数对革基布透气性、透湿性、吸湿性、柔软度及力学性能的影响。结果表明:当革基布面密度一定时,随着PAN纳米纤维质量分数的增加,革基布的透湿性、吸湿性、柔软度、撕裂性能提升,而透气性能和断裂强力有所下降;当PAN纳米纤维质量分数为20%时,革基布的透湿率提升了15.19%,吸水量提高了23.53%,柔软度增加了38.17%;经碱处理后,革基布的亲水性有了明显改善,透湿率提升了23.81%,吸水量提高了42.26%,柔软度提高了23.20%。

Abstract:

In order to further improve the water-vapor transmission rate and softness of polyester/polyamide 6 (PET/PA6) hollow microfiber synthetic leather base, polyacrylonitrile (PAN) nanofibers were mixed with PET/PA6 microfibers to prepare PAN-PET/PA6 micro/nano microfiber synthetic leather base by hydro-entanglement and alkali treatment. The effects of PAN nanofiber mass fraction on the air permeability, water vapor permeability, moisture absorption, softness and mechanical properties of leather base were analyzed. The results show that the water vapor permeability, moisture absorption, softness and tear strength were improved with the content of PAN nanofibers increase for the same areal density, but the air permeability and breaking strength were decreased. When the content of nanofibers was 20%, the water vapor permeability of the base was increased by 15.19%, the moisture absorption 23.53%, and the softness was increased by 38.17%. After alkali treatment, the hydrophilicity of base was obviously improved. The water vapor permeability was increased by 23.81%, the moisture absorption was increased by 42.26%, and the softness was increased by 23.20%.

Key words: polyester/polyamide 6 microfiber, polyacrylonitrile nanofiber, spunlace, synthetic leather base, fiber modification, moisture permeability
