Technical Field
The invention relates to the technical field of down feather pretreatment, in particular to application of washing equipment in a pretreatment process of nano water-repellent down feather.
Background
The down feather is an animal protein fiber, ten million triangular tiny air holes are densely distributed on down feather spherical fiber, the down feather spherical fiber can contract and expand along with the change of air temperature, the temperature adjusting function is generated, the hot air emitted and flowing by a human body can be absorbed, and the invasion of external cold air is isolated. However, when the down meets water, the water is attached to the fibers, so that air holes among the fibers are reduced, the down contracts, and the heat preservation and temperature regulation effects of the down are greatly reduced.
At present, the technology of applying the nano water-repellent material to the surface of down fibers is adopted to ensure that the down can obtain better water repellency, and the defect that the heat preservation effect of the down is reduced when the down meets water is overcome. The production of the nanometer water repellent down feather is generally that the nanometer material is mixed with water and then added with the down feather for stirring and soaking, and then the nanometer material is attached to the surface of the down feather after dehydration and drying, thereby increasing the hydrophobic capability of the down feather.
The above prior art solutions have the following drawbacks: some grease and impurities are usually attached to the down feather raw material, the removal rate of the grease and the impurities in the common washing step is low, and the residual grease and the impurities can influence the adsorbability of the nano material on the surface of the down feather when the down feather is mixed with the nano material, so that the water repellent effect of the down feather is reduced.
