Title (EN) METHOD FOR PREPARING ANTI-SMOG NONWOVEN FABRIC

(ZH) 一种防雾霾无纺布的制备方法
Abstract:
(EN) Provided is a method for preparing an anti-smog nonwoven fabric, which relates to the technical field of nonwoven fabric preparation. The method comprises: selecting a zwitterionic polyurethane containing a betaine group as a raw material; configuring the raw material into a first solution and a second solution having mass fractions of 15-35% and 3-10%, respectively; using electrospinning technology to spin the first solution so as to prepare a nonwoven fabric scaffold having a diameter of 1.0-2.0 μm; spinning the second solution on the nonwoven fabric scaffold to obtain a nanofiber of 200 nm-500 nm, so that the nonwoven fabric scaffold and the nanofiber are interlaced to form an anti-smog nonwoven fabric having a large number of porous structures, the ratio between the amount of nanofiber to the amount of fiber that serves as the nonwoven fabric scaffold being 19:1-19. Since the fiber that is prepared by spinning the first solution is thick, the mechanical properties of the nonwoven fabric may be improved. In addition, the betaine group has a good antibacterial effect, and may prevent the spread of bacteria in smog.
(FR) L'invention concerne un procédé de préparation d'un tissu non tissé anti-smog, qui se rapporte au domaine technique de la préparation des tissus non tissés. Le procédé consiste : à sélectionner un polyuréthane zwitterionique contenant un groupe bétaïne en tant que matière première ; à configurer la matière première en une première solution et une seconde solution ayant respectivement des fractions massiques de 15 à 35 % et 3 à 10 % ; à utiliser une technologie d'électrofilage pour filer la première solution de façon à préparer un échafaudage de tissu non tissé ayant un diamètre de 1,0 à 2,0 µm ; à filer la seconde solution sur l'échafaudage de tissu non tissé pour obtenir une nanofibre de 200 nm à 500 nm, de telle sorte que l'échafaudage de tissu non tissé et la nanofibre sont entrelacés pour former un tissu non tissé anti-smog ayant un grand nombre de structures poreuses, le rapport entre la quantité de nanofibres et la quantité de fibres servant d'échafaudage de tissu non tissé étant de 19:1 à 19. Étant donné que la fibre qui est préparée par filage de la première solution est épaisse, les propriétés mécaniques du tissu non tissé peuvent être améliorées. De plus, le groupe bétaïne a un bon effet antibactérien, et peut empêcher la dispersion de bactéries dans le smog.
(ZH) 提供一种防雾霾无纺布的制备方法,涉及无纺布制备技术领域。该方法包括:选取包含甜菜碱基团的两性离子聚氨酯为原料,将原料分别配置成质量分数为15~35%和3~10%的第一溶液和第二溶液,利用静电纺丝技术将第一溶液纺丝制备直径为1.0~2.0μm的无纺布支架,并在无纺布支架上对第二溶液纺丝得到200nm~500nm的纳米纤维,使得无纺布支架和纳米纤维相互交错形成包含大量孔隙结构的所述防雾霾无纺布,其中,纳米纤维和作为无纺布支架的纤维的数量比为19∶1~19。由于第一溶液纺丝制备的纤维较粗,可以提高无纺布的力学性能。另外,甜菜碱基团具有良好的抑菌作用,可以防止雾霾中细菌的传播。
