Quantification of the Easiness for Woking and Comfortableness of Farm Working Clothes

农场工作条件艰苦。我们称这个州为“3K”；在日语中，Kitsui（坚硬），Kitanai（肮脏）和Kiken（危险）。为了降低3K度，改善更舒适的工作状态，我们对农场工作服进行了调查。特别是为农民在农业工作中减少紫外线（UV）的暴露，难闻的气味和农药中毒。得到的结果如下：1。紫外线在衣服中的透射对紫外线在衣服中的透射进行了基本和综合的研究。通过对衣物中纤维含量的估算，建立了衣物厚度的归一化方法。根据方法，我们发现紫外线的透射率很大程度上取决于材料和染色。利用Kubelka理论将紫外线透射分为两种贡献，作用机制不同；吸收和散射机制。此外，估计了农服吸收汗液的吸收系数和散射系数的极限范围，使紫外线照射小于1最小红斑剂量。阐明了黏附土壤对紫外线透射的影响及其机理。农用工作服异味气体的吸附。纤维的恶臭气体吸收量随纤维含水率的增加而增加。吸附量随湿度的变化而变化，当相对湿度超过85%时，吸附量急剧增加。在低湿度条件下，纤维的吸附可以用Langmuir吸附机理来描述，而在高湿度条件下，纤维的吸附增加可能是由于纤维吸附的水中有异味的溶解。农用工作服的去污剂吸收了农药。建立了气相色谱定量分析方法和去污力测试样品制备方法。考察了纤维种类、温度条件和表面活性剂浓度对纤维解吸农用化学品的影响。从研究中获得的结果和/或信息有助于我们部署农场工作服材料和设计农场工作服。此外，它们还帮助农民根据季节和/或天气调整工作服。少

Farm working is in severe condition. We call the state "3K" ; Kitsui (hard), Kitanai (dirty), and Kiken (danger) in japanese. To reduce the degree of 3K and improve working condition in more comfortable state, we investigated the farm working clothes. Especialy, the reduction of ultraviolet rays (UV) exposure, bad smell and poisoning by agricultural chemicals for farmer in agricultural work, is aimed. The results obtained are as follows :1. Transmission of UV rays through clothesThe UV rays transmission through clothes was basically and synthetically investigated. A normalization method for thickness was established by pilling clothes and by estimating the fibers content in clothes. Based on method, if found that the UV rays transmission greatly depends upon the materials and the dyeing. The UV rays transmission was separated into two kinds of contribution with different mechanisms using Kubelka theory ; absorption and scattering mechanisms. In addition, the limit range of the absorpti … More on and scattering coefficients so that the UV exposure is less than 1 minimal erythema dose was estimated for farm clothes absorbed sweats. The effects of adhered soils on the UV rays transmission and its mechanisms was clarified.2. The sorption of the bad-smelling gas for farm working clothes.The amounts of the bad-smelling gas sorbed for fibers increased with increasing the moisture content. Those amounts of sorption were depended upon humidity condition and abruptly increased with R.H.over 85%. In the low humidity, the sorption can be descrived by Langmuir's sorption mechanisms and in the high humidity, this increase may be caused by dissolution of bad-smelling gas in water sorbed by fibers.The detergency for the farm working clothes sorbed the agricultural chemicals.The method for quantitative analysis making use of gas-chromatograhy and for preparing samples for test of detergency were established. We evaluated the effects of kinds of fibers, conditions of temperature and concentrations of surfactant for desorption of agricultural chemicals on fibers.The result and/or information obtained from the study help us to deplop farm working clothes materials and to design farm working clothes. Moreover, they help farmars to adjust their working clothes depending upon the season and/or weather. Less
