摘要
将以纳米TiO2作为近红外光反射剂的近红外光反射锦纶6母粒和以纳米锡锑氧化物(ATO)作为近红外光吸收剂的近红外光吸收锦纶6母粒与锦纶6切片共混纺丝,制得具有防红外透视功能的锦纶纤维,研究纺丝工艺参数对纤维红外透过性能及力学性能的影响。结果表明:当两种防红外透视材料总添加质量为3%,添加质量比4∶2,纺丝温度248℃、255℃、260℃、260℃、260℃,卷绕速度4200m/min,牵伸倍数1.4时,纺丝过程稳定,纤维的力学性能良好,所得纤维制备的织物在700～1200nm波长范围内红外透过率低于20%。因此,以纳米TiO2和纳米ATO为功能材料,通过共混熔融纺丝工艺可以制备兼具良好力学性能与防红外光透过效果的锦纶6纤维。
Abstract
Nylon fibers with resistance to infrared see-through were successfully prepared via melt spinning,which was achieved by blending nylon 6 chips with two functional masterbatches,one containing nano-TiO2 as a near-infrared reflector and the other containing nano-ATO as a near-infrared absorber.The study investigated the effects of spinning process parameters on the infrared transmission and mechanical properties of the fibers.Under optimized process conditions,which included a total functional additive content of 3wt% at a blending ratio of 4∶2,a spinning temperature profile of 248℃,255℃,260℃,260℃,and 260℃,a winding speed of 4200 m/min,and a draw ratio of 1.4,the spinning process remained stable and the resulting fibers exhibited good mechanical properties.Fabrics made from these fibers demonstrated an infrared transmittance of less than 20% within the wavelength range of 700 to 1200 nm.This study demonstrated that using nano-TiO2 and nano-ATO as functional materials,nylon 6 fibers possessing both excellent mechanical performance and effective resistance to infrared see-through could be prepared via a co-blending melt spinning process.
