织物近红外光透射率的影响因素

摘要

Different fabric weaves, densities of fabric, yarn twists and moisture contents were discussed to study the 700-1 400nm near-infrared light transmittance through undyed woven cloth. The results show that changes in three-elementary weaves had no significant correlation with the near-infrared light transmittance. The correlation between density of fabric and near-infrared light transmittance was negative in the range of the fabric densities studied. The transmittance would increase as the yarn twists added within a certain range. High moisture content would increase the near-infrared light transmittance.%分别从织物组织结构、经纬纱密度、纱线捻度、水分含量等单因素条件变化来分析织物的近红外透光性能.结果表明,组织结构的变化对织物近红外光透射率的影响有限,织物的近红外透射率随着织物密度的增大而减小；在一定的捻度范围内,织物的近红外光透射率随着捻度的增大而增大；织物回潮率的增加会使近红外透射率增大.
