摘要/Abstract

摘要：

为织造在特殊环境中具有耐久性的纺织品,以聚全氟乙丙烯(FEP)纤维为原料,经加捻、合股工艺制备FEP纱线,通过半自动织布机织造出幅宽为250 mm、厚度为0.51 mm的FEP平纹织物。借助电子拉力试验机、动态接触角测定仪、织物透气量仪、织物透湿量仪、织物耐磨仪、紫外冷凝老化试验箱、差示扫描量热分析仪、X射线衍射仪、傅里叶红外光谱仪等对FEP纱线及其织物性能进行分析表征。结果表明:FEP纱线力学性能优良且具有疏水性;FEP织物具有较好力学性能,耐高温且耐化学试剂、耐老化性能优异,经酸碱、有机溶剂处理后织物的热性能、结晶结构、化学结构及力学性能均未发生明显变化;经紫外光辐照处理,织物力学性能未发生明显变化,表明FEP织物可适用于特殊环境。

Abstract:

In order to weave textiles with the durability in special environments, poly(fluorinated ethylene-propylene)(FEP) yarns were prepared from FEP fiber by twisting and doubling. The plain weave fabric of FEP with the width of 250 mm and the thickness of 0.51 mm was woven by a semi-automatic loom. Electronic tensile testing machine, dynamic contact angle tester, fabric air permeability tester, fabric moisture permeability tester, abrasion tester, ultraviolet condensation aging test box, differential scanning calorimeter, X-ray diffractometry and Fourier transform infrared spectroscopy were applied to analyze and characterize the properties of yarns and fabrics. The results show that FEP yarns have good mechanical properties and hydrophobicity. FEP fabric have excellent mechanical properties, high-temperature resistance and excellent chemical resistance and aging resistance. The thermal performance, crystalline structure, chemical structure and mechanical properties of the fabrics treated with acid, alkali and organic solvents have no significant change. The mechanical properties of the FEP fabrics treated under UV irradiation have no significant change, showing the feasible application of FEP fiber fabric in special environments.

Key words: poly(fluorinated ethylene-propylene) fiber fabric, industrial textile, mechanical property, chemical resistance, aging resistance
