摘　　要：以普通高强型GHT、高模低缩型HMLS和高强超低缩型SLS涤纶工业丝为研究对象,研究了活化油剂上油及干燥条件对纤维力学、热性能的影响。结果表明:干燥处理(75℃)后涤纶工业丝的线密度和结晶度增大,而断裂强度、杨氏模量、热收缩性能、声速取向因子及声速模量出现不同程度的下降,断裂伸长率未有明显变化。上油处理后,涤纶工业丝的线密度增大,断裂强度、杨氏模量、热收缩率与热收缩力降低,而断裂伸长率和结晶度未有明显变化。GHT和HMLS涤纶工业丝上油处理后的声速取向因子和声速模量较原丝均有上升。对比其他两类工业丝,SLS涤纶工业丝经上油和干燥(75℃)后,力学强度和模量损失有限,热收缩率降低明显,尺寸稳定性好,结晶度增加,更适合用于涤纶工业丝的活化改性及应用。The activated polyester industrial yarn is a new type of industrial yarn.It can form good adhesion with rubber,PVC and other polymer matrices due to the reactive activating oiling agent attached to its surface.The original composite molding process of"spinning oiling-predipping-RFL dipping-rubber compounding"can be simplified into"activated oiling-RFL dipping-rubber compounding"because of the activated filaments.This technology can prepare polyester fabric reinforced composites with light weight,deformability,high strength,high modulus and good dimensional stability,which can be widely used in automotive industry,construction engineering and other fields.Activating oil agents play an important role in the preparation of activated polyester industrial yarns.As an important auxiliary agent to endow surface activity of polyester industrial yarns,the activating oiling agent is usually dynamically oiled through nozzles or tankers after fiber preparation.When the activating oil agent contains a humidity sensitive group,it is generally necessary to dry the oiled fibers in order to prevent excess water molecules from interfering the activation reaction after the unsealing section of the activating oiling agent.At present,there is little research on the influence of the activating oiling agent and drying treatment on the original properties of polyester industrial yarns.For this reason,three kinds of common polyester industrial yarns(general high strength GHT,high modulus low shrinkage HMLS and high strength ultra-low shrinkage SLS)were chosen as the raw materials.The yarns were treated with activating oil agents,and dried at room temperature or 75℃.The effects of activating oil agents and drying conditions on the linear density,mechanical properties,thermal shrinkage properties,sonic orientation and crystallinity of polyester industrial yarns were thus investigated.The experimental results show that the linear density and crystallinity of the three polyester industrial yarns increase slightly after drying treatment,whi
