| 吸湿性：是指纺织材料从气态环境中吸着水分的能力。或纺织材料在空气中吸收或放出水蒸气的能力。 Hygroscopicity: refers to the ability of textile materials to absorb moisture from gaseous environment. Or the ability of textile materials to absorb or emit water vapor in the air. 润湿性：是指纺织材料从水溶液中吸着水分的能力。 Wettability: refers to the ability of textile materials to absorb water from aqueous solutions. 吸湿状态与多少影响到： Hygroscopicity and how much it affects: 纤维的性能、纺织工艺、织物舒适性、纺织材料的计重核价 Fiber properties, textile technology, fabric comfort, weight checking of textile materials 1 One 回潮率与含水率 Moisture regain and moisture content 回潮率W：纺织材料中所含水分重量对纺织材料干重的百分比。 Moisture regain W: The percentage of moisture content in textile materials to dry weight of textile materials. 含水率M：纺织材料中所含水分重量对纺织材料湿重的百分比。 Moisture content M: The percentage of moisture content weight in textile materials to wet weight of textile materials. 2 Two 标准状态下的回潮率 Moisture regain under standard condition 纺织材料在标准大气条件下，从吸湿达到平衡时测得的平衡回潮率。 Under standard atmospheric conditions, the equilibrium moisture regain of textile materials is measured when moisture absorption reaches equilibrium. 国标准规定的为： The national standards stipulate that: 大气压力：1个标准大气压，即101.3kPa（760mmHg柱） Atmospheric pressure: 1 standard atmospheric pressure, 101.3 kPa (760 mmHg column) 3 Three 公定回潮率 Designated moisture regain 贸易上为了计重和核价的需要，由国家统一规定的各种纺织材料的回潮率。以标准回潮率为依据，但不等于标准回潮率。 In trade, for the purpose of weight calculation and price verification, the moisture regain rate of various textile materials is uniformly stipulated by the state. The standard moisture regain rate is the basis, but it is not equal to the standard moisture regain rate. 天然纤维由于有杂质和伴生物，纱线的公定回潮率与纤维的公定回潮率不一致。 Due to impurities and associated organisms in natural fibers, the nominal moisture regain of yarns is not consistent with that of fibers. 公定重量：纺织材料在公定回潮率时的重量。 Fixed Weight: The weight of textile material at a given moisture regain. |
