| One of them is C6-based fluorochemical water-repellent, which conforms to environmental protection. In this research, low melting point polyester of needle punching nonwovens were finished by C6-based fluorochemical water-repellent. About hydrophobicity test, the contact angles were constantly between 118 and 130゜and the rating results of spray test were between 3 and 4 level. The wicking height of finished fabric was 0 cm. The result show finished have better hydrophobicity. Air permeability of fabric was between 1 and 1.49m/s. After the fabric washed for 20 times, the contact angles were dropping 7゜and spray test were dropping 1 level. Above-mentioned results, one of them is 1.51% take up rate was a better option. 現今鞋材織物，需具適當之透氣與撥水性能。添加少量氟系撥水劑即具顯著的撥水效果，耐久性亦優於有機矽類，C8型的氟系撥水劑，以浸漬壓吸法進行撥水加工。親疏水測試之結果為接觸角介於118~130°，撥水評級介於3~4級，且加工前後經虹吸測試證明布面濕潤長度由80mm下降到0mm，顯示加工後織物疏水性優良。而透氣度介於1~1.49m/s，與原樣差異不大表示加工後變異不大，但水洗20次後，接觸角下降17°，撥水評級下降1級。綜合以上結果，其中上劑率1.51%時可得到128°之接觸角，且可耐水洗20次後撥水評級下降1級，對鞋材已具有良好的耐用性，為適當的加工條件。 |
