現今多數透濕防水產品的濕式微多孔成形為藉由DMF置換產生的微細孔洞，但DMF的高生物毒性，對於加工人員、消費者及環境並不友善，有鑒於此，本研究論文以透濕防水薄膜之乾式塗佈加工製程條件討論DMF Free使用量為基礎，嘗試藉由不同溶劑沸點產生孔洞不一的連續性孔洞製成乾式微多孔膜，並以能穩定量化為出發點，使研發技術更符合國際趨勢所需。
此外文中分別在溶劑量MEK/TOL比例30、40、50及H20/MEK比例30、40、50之間，並在加工環境恆溫恆濕狀況下進行組合加工，實驗結果顯示在MEK/TOL:H20/MEK=30:30時，乳化PU還不夠均勻，烘乾成膜的孔洞並不是連續性所以原膜透氣0cfm，但經過逐步提高MEK/TOL:H20/MEK=50:50時，其乳化穩定在成膜時溶劑揮發後原膜內部有形成孔洞並達穿透之效，水壓6100mmH20，透濕12902g/m2*24hr，透氣值0.19cfm，此為最佳條件，另外會再以不同試驗條件與現有透濕防水膜於物性上做一比較區分，研發出綠色環保的產品，並於水壓、透濕及透氣上規格化應用於不同成衣紡織上的需求，深入各項新製程、新技術之開發與現有產品改良，以期能繼續維持競爭優勢。

Nowadays, most moisture-permeable and waterproof products of the wet micro-porous is formed the micro-hole produced by DMF replacement. However, the high bio-toxicity of DMF is not friendly to the processing operators, consumers and the environment. In view of this, Based on the DMF Free usage, the dry micro-porous membrane was prepared the continuous pores by using the different solvent boiling points. The stability of the porous microporous membrane was made as the starting point, so that the R & D technology was more in line with international trends.
In addition, the results were shown respectively with the ratio of MEK / TOL is 30, 40, 50 and H20 / MEK 30, 40, 50 in the processing environment of constant temperature and humidity conditions. The experiment results is shown that in MEK / TOL: H20 / MEK = 30: 30, the emulsified PU is not mixed enough so that the pores after drying of the membrane is not continuous so the membrane permeability 0 cfm, but after increasing the ratio of MEK / TOL: H20 / MEK to 50:50. The emulsification is stability so that the film after the solvent evaporation forming the membrane hole and continuous. The effect makes the water pressure is 6100 mmH20,the moisture is 12902 g/m2*24hr and the breathable value is 0.19cfm which is the best conditions. The others will do different test conditions and compete with the existing moisture-permeable waterproof membrane in the physical properties. Developing a green product, and in water pressure, moisture permeability and breathable on the standardization of the different textile needs. Reserch the new process, new technology to improvement of existing products in order to continue to maintain a competitive advantage.
