Abstract

The invention discloses a down jacket oil-proof coating and a production method thereof, and the oil-proof coating is prepared from the following raw materials: an auxiliary agent, polytetrafluoroethylene, silicon dioxide aerogel powder, a polyurethane solution, a foaming agent, resin, polyether polyol, isocyanate, a catalyst, polyethylene glycol adipate, polypropylene glycol, a filling agent and a curing agent, foaming slurry prepared from a foaming agent is coated on the coating, so that the coating has heat insulation and heat preservation functions, the oil-proof coating has a better heat insulation effect, the interior of the down jacket cannot be transferred to the coating, the temperature of the coating is lower, and the surface tension of oil stain liquid falling onto the coating cannot be reduced; the oil stain liquid is prevented from immersing into the coated fabric, so that the oil stain resistance of the down jacket is improved through the oil-proof coating, and the wearing time of the down jacket is prolonged.

Description

technical field [0001] The invention relates to the technical field of clothing, in particular to an oil-repellent coating for down jackets and a production method thereof. Background technique [0002] Clothing refers to the general term for clothes and footwear, generally refers to clothes. With the improvement of people's living standards, the types and functions of clothes are gradually increasing. Down jackets are a kind of clothing. Down jackets are tops filled with down and have a very strong The thermal insulation performance is suitable for people in cold areas. [0003] Down jackets are commonly used clothing for cold resistance in winter, and down jackets are filled with down fillings, which makes the down jackets more troublesome in the process of cleaning and drying. Therefore, in order to reduce the cleaning times of down jackets, there is a certain demand for the anti-fouling ability of down jackets. The traditional down jacket fabric has poor oil resistance,...
