紡織品為民生必需品之一,近年來,隨著科技的進步以及生活水準的提高,民眾對於穿著舒適性的要求也越來越重視,而這也成為紡織產業技術不斷地向前邁進的驅動力。目前的紡織產業多半朝向舒適性與機能性等的紡織品發展,因此,各種智慧型與功能型的織物因應而生,透濕防水塗層織物就是其中之一。 「透濕防水性」紡織品是一種能防雨水穿透又可將汗液蒸氣排出的機能性布料,因此它不會在衣著內部結露而導致濕冷、不舒服之現象,是戶外運動之最佳選擇,但透溼防水卻是兩個相互矛盾條件下的存在,因此,找出織物塗佈時之最佳參數值,使得織物能夠兼具防水性及良好透濕性是本論文研究之目的。 本研究針對水性聚胺基甲酸乙酯(Water based PU, WPU)進行之塗佈加工,以田口方法測試能達到最佳透濕度與防水效果的參數值;其實驗的方式為採用L9(34)直角表探討4個3水準的因子:二氧化矽添加量、矽酸膠添加量、架橋劑添加量、塗佈黏度。經田口方法測試後,求得最佳的參數值為:二氧化矽添加量0g,架橋劑添加量0.5g,矽酸膠添加量0g,樹脂塗佈黏度15000cps。
Textiles are one of the necessities of people’s daily life. In recent years, with the progress of science and technology and the improvement of living standards, people are requiring more and more about the wearing comfort which has become the driving force of the textile industry to move forward continuously. Hence, the current textile industry tends to focus on the comfort and functionality of the textile development, therefore, a variety of intelligent and functional fabric have been born in response to these, and, “moisture-permeability waterproof” coating fabric is one of them. “Moisture-permeable waterproof” textile is a functional fabric that is rain proof while the moisture can penetrate outward so the sweat vapor will not be exposed inside the clothing and lead to uncomfortable conditions like wet and cold.Hence, the textile is the best choice for outdoor sports and leisure use.However, moisture permeability and waterproof are two contradictory conditions. Therefore, how to obtain the best parameters when the fabric is coated so that the fabric can be both waterproof and moisture permeability is the purpose of this study. In this study, the water-based polyurethanes (WPU) was coated and tested by Taguchi method to get the pamameters for achieving the best moisture permeability and water resistance. The experimental method was as follows: To explore the moisture permeability and water resistance for three levels of four factors as the amount ofsilicaadded, silicic acid added, bridging agent added, and coating viscosity by using the L9(34) orthogonal array. After the application of Taguchi method, the optimum parameters were as follows: the addition amount of silica was 0g, the addition amount of bridging agent was 0.5g, the dosage of silicic acid was 0g, and the viscosity of resin coating was 15000cps.
