Embodiment 1

[0049]Get 12 grams of perfluorohexyl ethyl methacrylate, 12 grams of behenyl acrylate, 2 grams of styrene, 1.5 grams of maleic acid (perfluorohexyl ethyl) glycidyl ester, 1.5 grams of work single I ( It is produced by reacting 1 mol of HDI trimer with 1 mol of stearyl alcohol, 1 mol of perfluorohexyl ethyl alcohol, and 1 mol of hydroxyethyl acrylate), 5.2 grams of dipropylene glycol ether, 5 grams of Ethoqual C / 25 (ethoxylated quaternary ammonium salt ), 0.3 gram of acetic acid, 59.3 gram of water, heated up at 55 degrees, and emulsified at high speed for 60 minutes to obtain a pre-emulsion; nitrogen was then passed for 30 minutes while controlling the temperature to be 62 degrees Celsius. Add 0.2 gram of azobisisobutylamidine hydrochloride and 1 gram of vinyl chloride, and keep the reaction for 8 hours. Finally, lower the temperature of the system to room temperature and filter through a 300-mesh filter cloth to obtain the water and oil repellent.

Abstract

The invention provides a water and oil proofing agent specially used for cotton fabric obtained via whole low temperature dyeing and finishing, and a preparation method and applications thereof. The water and oil proofing agent specially used for cotton fabric obtained via whole low temperature dyeing and finishing comprises, by mass, 25 to 35% of a fluorine containing polymer, 2 to 8% of a surfactant, 1 to 10% of an auxiliary agent, and water. The water and oil proofing agent possesses excellent water and oil proofing effect, is prepared from special raw materials, and is especially suitable for cotton fabric obtained via whole low temperature dyeing and finishing.

Description

technical field [0001] The invention relates to the field of textile auxiliaries, in particular to a special waterproof and oil-repellent agent for cotton fabrics subjected to all-low temperature dyeing and finishing processing, as well as its preparation method and application. Background technique [0002] In recent years, with the promulgation of national laws and regulations and the improvement of people's awareness of environmental protection, the traditional dyeing and finishing industry with high energy consumption and high pollution discharge has put forward the requirement of technological progress. With the ability of the vast number of scientific and technological workers, the dyeing and finishing of cotton fabrics is gradually moving towards an all-low temperature process with energy saving, low emissions, and targeted treatment. This process can largely retain the "beneficial" components on cotton fibers and remove "Unfavorable" components. [0003] The results...
