This research reports the designing and the optimization of a waterproof breathable fabric. A new waterproof breathable fabric made by coating a double sided spacer knit with a mixture of an acrylic paste and a fluorocarbon resin is presented. The treated fabric can be used for producing outdoor garments. The surface states of treated samples were characterized by using the assessment of the coating add-on (%), water contact angle (°), surface free energy (mN·m−1), and roughness (mm). The main coating process parameters were studied by using the Box-Behnken experimental design. It was proved that the quantity of acrylic paste (g·m−2) and the reticulation time (min) have the most significant effect on the coating add-on value (%). The surface free energy (mN·m−1) is affected by the three studied factors. Roughness was also evaluated before and after the coating treatment. However, no significant variation in values was noticed. Optimum responses are obtained with 2.71 % of fluorocarbon resin, 412.00 g·m−2 of acrylic paste, and a reticulation time equal to 13.52 minutes. Optimized values for the coating add-on, SFE, and roughness are equal to 79.716 %, 29.17 mN·m−1, and 0.058 mm, respectively.

间隔防水透气织物的开发和表面状态表征

这项研究报告了防水透气织物的设计和优化。提出了一种新的防水透气织物,该织物通过用丙烯酸糊和碳氟化合物的混合物涂覆双面间隔针织物制成。经处理的织物可用于生产户外服装。通过评估涂层添加量(%),水接触角(°),表面自由能(mN·m -1)和粗糙度(mm)来表征处理后样品的表面状态。使用Box-Behnken实验设计研究了主要的涂层工艺参数。已证明丙烯酸糊的量(g·m -2)和网状时间(min)对涂料添加值(%)具有最显着的影响。表面自由能(mN·m -1)受三个研究因素的影响。还在涂层处理之前和之后评估粗糙度。但是,没有发现值的显着变化。用2.71%的氟碳树脂,412.00 g·m -2的丙烯酸糊料和网状时间等于13.52分钟可获得最佳响应。涂层添加量,SFE和粗糙度的最佳值分别等于79.716%,29.17 mN·m -1和0.058 mm。
