对防水面料各种功能性的测试方法及评价指标应当有明确的要求,避免消费者在购买的过程中被误导和欺骗? It is recommended that standard-setting units introduce and improve relevant standards as soon as possible. On the one hand, it will help standardize the consumer market, provide consumers with a basis for purchasing, and reduce blindness; on the other hand, it will also help guide production and provide enterprises with easy control of product quality. indicators to increase the fairness of competition among various clothing brands ?</p
防水面料基本都是化学纤维织物制成,当户外环境比较干燥的时候,就会产生静电问题,表现为衣服易起毛起球、容易沾染灰尘污垢、贴近皮肤产生静电吸附。
The test method for the solar ultraviolet protection performance of textiles, the expression, evaluation and labeling of the protection level. The test principle is to irradiate the sample with single-color or multi-color UV rays, collect the total spectral transmission rays, and measure the total spectral transmittance. t (λ), and calculate the ultraviolet protection coefficient upf value of the sample ?可采用平行光束照射试样,用一个积分球收集所有透射光线;也可采用光线半球照射试样,收集平行的透射光线? ?在实际的操作中,检测仪器可以自动计算出样品的upf值和t(λ)? ?当样品的upf值大于50时,表示为“upf>50”? ?按该标准规定,当样品的upf>40,且t(uva)av<5%时,可称为“防紫外线产物”? ?</p
现有国家标准和行业标准,各方法的评价的指标不一样,抗静电织物使用不同测试方法得到的结果也不具有可比性? ?电荷面密度法能较好的模拟防水面料在实际穿着时的起电过程,是测试防水面料抗静电性能比较适宜的方法? ?纺织品防紫外线辐射的评定参数采用的是紫外线防护系数upf值,它表示皮肤无防护时计算出的紫外线辐射平均效应与皮肤有织物防护时计算出的紫外线辐射平均效应的比值?
