Problems solved by technology

At present, degreasing agents are often used to wash and degrease down, but most of the degreasing agents used are surfactants, which will affect the bulkiness of down while improving the degreasing rate, and will produce a lot of foam during washing, requiring a lot of water for rinsing. Thereby increasing the workload of wastewater treatment and the investment of cleaning costs

Abstract

The invention discloses a down feather rapid degreasing technology, and relates to the technical field of down feather processing. The technology comprises following steps: (1) primary preheating; (2)primary degreasing; (3) primary rinsing; (4) secondary preheating; (5) secondary degreasing; and (6) secondary rinsing. Through preheating operation before a degreasing agent is sprayed, grease on down feathers is activated, and thus the degreasing effect is enhanced. The degreasing effect is guaranteed through twice degreasing, and the grease on down feathers is effectively removed. By using a degreasing agent, the degreasing effect is guaranteed, at the same time, the using amount of water is reduced, and the degreasing rate can reach 99% or more. Furthermore, the wastewater generated by degreasing is easy to process, and after a simple treatment, the sewage can be directly discharged.

Description

Technical field: [0001] The invention relates to the technical field of down processing, in particular to a fast degreasing process for down. Background technique: [0002] Down is the fluff that grows on the abdomen of geese and ducks in the shape of reed flowers. Since down is a kind of animal protein fiber, there are tens of thousands of small triangular pores densely covered on the down ball-shaped fiber, which can shrink and expand with the change of temperature, and has the function of temperature adjustment, which can absorb the flowing hot air from the human body and isolate the invasion of cold air from the outside. . From the analysis of bulkiness detection, down is one grade higher than silk, cotton and other thermal insulation materials, and its economic value is much higher than other thermal insulation materials. [0003] In recent years, people's demand for down clothing and products is increasing, and the requirements for down quality are also getting highe...
