padding: 0px; cursor: text; font-size: 16px; overflow-wrap: break-word !important; outline: none 0px !important;"> 水滴的直径级为100~300μm,水汽分子的直径为4x10μm,利用水滴和水蒸气的直径差异来实现织物的拒水透湿。即采用织物的经纬交织间的孔隙或织物复合物的孔径介于水滴的最小直径和水汽分子直径之间达到拒水透湿的目的。</span></p><p style="text-align: left;

outline: none 0px !important;"> 纯棉高密织物当其表面潮湿时,棉纤维吸水溶胀,从而减小了织物的孔隙,能达到拒水透湿的目的。只有高水压的水才能透过织物,达不到很高的拒水性。这类织物的透湿属于纱线间孔隙的自然扩散,虽然防水性较差,但其优越的手感和良好的透湿性,使该织物仍被用于军事和其他方面,在拒水透湿市场上仍有一-席之地。其代表产品为英国的文泰尔(Ventel)防雨布。</span></p><p style="text-align: left;

padding: 0px; cursor: text; font-size: 16px; overflow-wrap: break-word !important; outline: none 0px !important;"> 近年来,随着纺丝技术的发展,利用超细长丝(0.1~0.3dtex)制成的超高密织物大量涌现,超微细长丝织物并不像文泰尔防雨布那样利用纤维和纱线的吸水溶胀来提供和加强防水性能,而是利用纤细的长丝和紧密结构和对坯布的收缩整理,使织物具有良好的拒水性,同时还具有一定的透湿性。即使不采用拒水整理也可以达到9.8-14.7kPa的耐水压。这类织物以日本帝人公司开发的微隙织物(micro porous fabric)为代表。三、涂层织物织物经过直接或转移涂层加工,使织物表面被涂层剂所封闭,因而得到拒水性。涂层剂包括聚氨酯、聚氯乙烯、聚丙烯酸酯、有机硅橡胶、聚四氟乙烯等。织物的透湿性则通过涂层上的特殊配方或工艺形成的微孔结构或亲水基团的作用来获得。</span></p><p style="text-align: left;

padding: 0px; cursor: text; font-size: 16px; overflow-wrap: break-word !important; outline: none 0px !important;"> 微孔涂层可以通过如下方法来实现;</span></p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important;

max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br style="max-inline-size: 100%; margin: 0px;

outline: none 0px !important;"> (2)相分离:在湿法凝固涂层工艺中,利用聚氨酯做涂层剂,选DMF为溶剂,选水为非溶剂。用DMF将聚氨酯溶解成乳化液,涂在织物上,浸人水中。利用DMF与水的混溶性,让水在涂层膜中置换DMF,降低DMF的浓度,促使聚氨酯沉积在织物上构成微孔膜。日本东丽的En-trant、美国 Burlington 公司的 Ultrex 即属此类。</span></p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br style="max-inline-size: 100%; margin: 0px;

outline: none 0px !important;"> (3)相位倒置:在织物上涂上一层聚氨酯溶剂,在经过选择的蒸发阶段中,溶剂首先被除去,聚氨酯则以微孔形式沉积在织物上。如比利时UCB Speciality Chemicals/B 公司的Ucecoat 2000。</span></p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px;

max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br style="max-inline-size: 100%; margin: 0px;

outline: none 0px !important;"> 亲水性涂层的透湿性是利用涂层剂高分子热运动形成的自由体积及高分子间的空间,构成了允许水蒸气分子通过的孔。由于涂层剂聚氨酯溶液中含有亲水性基团,汗液水蒸气分子通过及附一扩散一解吸的作用透过涂层。这类产品有比利时UCB Speciality Chemicals/B公司的Jcecoat 2000NPU,德国拜尔(Bayer)公司的 Impraperm、美国 Baxenden/GB公司的Witcoflex/stay-ool。</span></p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br style="max-inline-size: 100%; margin: 0px;

outline: none 0px !important;"> 3.复合型涂层</span></p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important;

padding: 0px; cursor: text; font-size: 16px; overflow-wrap: break-word !important; outline: none 0px !important;"> 在微孔结构上再作亲水性整理,用来提高微孔涂层的拒水透湿性。如在Ucecoat 2000 微孔膜上再涂上Ucecoat NPU整理剂。在选择亲水性整理剂时,注意不要造成不可接受的透湿性损失。</span></p><p style="text-align: left;

padding: 0px; cursor: text; font-size: 16px; overflow-wrap: break-word !important; outline: none 0px !important;"> 拒水透湿层压织物使将普通织物与一层拒水透湿薄膜,通过层压工艺复合在一起,成为拒水透湿织物。</span></p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important;
