|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.
