纤维表面微纳孔结构调控面料日间持续降温性能研究
Research on the regulation of daytime continuous cooling performance of fabrics through micro-nano pore structures on fiber surfaces
摘要
Abstract
In response to the persistent high-temperature climate,existing cooling fabrics face the challenge of being unable to achieve large-scale and sustained cooling.To address this issue,a sheath-core blended fiber was prepared through melt spinning,using a sheath material derived from the granulation blend of polyamide 6(PA6),polyethylene terephthalate(PET),and silicon dioxide particles(SiO2),with(PA6)as the core material.This fiber,treated with an alkali process to create a surface with micro-nano pore structures,was then used to produce a 145 g/m2 single jersey fabric on a 32-gauge circular knitting machine.Compared to untreated smooth PA6/PET fabric,the alkali-treated fabric with micro-nano pore structures exhibited an increase in reflectance of up to 12.52%in the visible light spectrum(380～760 nm)of solar radiation.Under outdoor clear sky conditions with an average solar power of 746 W/m2,the fabric demonstrated a cooling effect exceeding 3℃compared to cotton fabric.This process offers advantages of high efficiency and low cost in the production of continuous cooling textiles,showing potential for mass production and wide application.关键词
