Abstract

The invention discloses a preparation method of a water-repellent oil-repellent anti-staining silk fabric. The preparation method comprises following steps: silk fabric obtained through tailoring is washed with ethanol, is subjected to air drying, and is immersed in a fluorine containing finishing agent solution for 5 to 6min; the silk fabric is taken out from the fluorine containing finishing agent solution, is subjected to rolling at a mangle expression of 80 to 90%, is spread, is subjected to pre-drying for 1 to 3min in a baking oven at 60+-2 DEG C, is subjected to drying for 1 to 2min at 130+-2 DEG C, and then is taken out from the baking oven. The preparation method is rapid and convenient, is low in cost, and high in efficiency; the water-repellent oil-repellent anti-staining silk fabric is capable of maintaining the original permeability and comfortableness advantages, possesses water repellence and oil repellence, the oil contact angle is capable of reaching 97 DEG, and the water contact angle is capable of reaching 140 DEG. The water-repellent oil-repellent anti-staining silk fabric possesses water repellence performance and oil repellence performance, and the stain resistance lasts long.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a method for preparing a water- and oil-repellent anti-fouling silk fabric. Background technique [0002] As a precious, ancient, rare and noble textile fabric, silk fabric is composed of various amino acids through condensation reaction. Under adverse conditions such as water and oil, the silk fiber will be damaged, showing dark yellow and easy to break , rough, affecting the use of silk fabrics, so silk needs a special detergent after daily use and washed at a suitable temperature. However, silk often does not get proper care after daily use and the fabric is damaged. These problems have always plagued the development of silk fabrics and limited the use of silk fabrics. Contents of the invention [0003] In view of the above deficiencies, the present invention provides a method for preparing a water- and oil-repellent anti-fouling silk fabric, which uses a fluorine-containing finishi...
