Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: there are usually some grease and impurities attached to the down raw materials, and the removal rate of the grease and impurities in the ordinary washing step is low, and the residual grease and impurities will affect the mixing of the down and nanomaterials. When the adsorption of nano-materials on the surface of down is reduced, the water-repellent effect of down is reduced

Abstract

The invention discloses a pretreatment process of nanometer water-repellent down, and relates to the technical field of down pretreatment. The steps of the synthesis method are as follows: S1: loosen the down raw material, soak the down raw material in water; S2: soak the down raw material Drain the raw materials of down and down for later use; S3: prepare a washing solution, and add the washing solution to the washing equipment; S4: add the down and down drained in S2 to the washing equipment and stir together with the washing solution; S5: rinse the washed down with water Rinsing; S6: dehydrating and drying the rinsed down; obtaining the pretreated down raw material through the above six steps. The invention has the advantage of improving the adsorption effect of the down to the nano water repellent agent when it is treated with the nano water repellent agent.

Description

Technical field [0001] The present invention relates to the technical field of down procedure, in particular, to a pre-treatment process of a water washing equipment in the pre-treatment process of nano-refusal down. Background technique [0002] Down is an animal protein fiber, and the down spherical fiber is depleted with 10,000 triangular pores, which can shrink and expand with temperature, produce temperature control function, and absorb the human body to dissipate the flow of flow, and isolate the invasion of external cold air. However, when the down is in the water, the water is attached to the fiber, so that the air hole between the fibers is reduced, and the down shrinkage is reduced, so that the cost of the duvet is greatly reduced. [0003] It is currently used to apply nano-refusal materials to the surface of the down fiber surface so that the duvet can achieve better refusal water performance, which has resolved the defects in the downward water insulation. The produc...
