Durable feather oil absorbent felt, method for fabricating oil sorbent boom, and oil sorbent boom structure

A method of preparing a durable feather oil absorbent felt, wherein the method comprises the following steps:

• a) water repelling treatment:
• soak a feather oil absorbent felt into a water repellent reagent or spray the water repellent reagent into the feather oil absorbent felt by means of double-sided spray for water repellent treatment, whereas the feather oil absorbent felt is formed by thermal fusion of feathers and bicomponent fibers of polypropylene/polyethylene having a low melting point, whereas a weight ratio of the feathers to the bicomponent fibers of polypropylene/polyethylene having a low melting point is 70-85:15-30, and whereas the feather oil absorbent felt has an average surface density of 150 g/m2-400 g/m2;
• b) rolling and pressing by a roller:
• roll and press the feather oil absorbent felt after water repelling treatment by using a roller so as to obtain a liquid rate according to which weight of the water repellent reagent is 5-10% of weight of the feather oil absorbent felt after drying;
• c) drying and baking operation:
• put the feather oil absorbent felt after rolling and pressing into a drying oven for drying under 120° C.-135° C., and then bake the feather oil absorbent felt under 145° C.-150° C. to obtain a water repellent and oil absorbent feather oil absorbent felt.
