The invention discloses a method for processing and extracting eiderdown from feathers and washing eiderdown. The method comprises the steps of carrying out feeding, extracting, dust removal, stem absorption, washing, rinsing, dehydrating, drying, cooling, impurity removal and packing on the feathers. The eiderdown extraction comprises: adopting an eiderdown extracting tower, throwing the feathers into the eiderdown extracting tower, and making the rotation speed of a stirring device in the chenille eiderdown extracting tower be 40-50 turns/min; the washing procedure comprises: putting the feathers into water added with a washing agent, stirring and cleaning the feathers; the rinsing procedure comprises: cleaning the washed feather slurry repeatedly by water; and the drying procedure comprises: drying the dehydrated feathers to 50 to 70 percent of dryness through steam, dampening the feathers, drying the feathers by the steam, and repeating the procedure frequently. The method reduces the down loss rate to 1 percent from 5 percent, and improves the high value contents of down in a feather sheet from 82 percent to 98 percent so as to reduce down mechanical loss and achieve the effects of improving quality and reducing loss. The fluffy degree of the 90 percent eiderdown is improved from 13 cm to 18 cm.

The invention provides a down feather processing production technique. The down feather processing production technique includes steps of presorting, dedusting, separating, washing and drying of the down feather, soaking, secondary dewatering and drying, cooling, checking and packaging. The separating step includes separating dedusted down feather into nap, large, medium and small feather and large and small feather shafts; the washing step includes washing the feather more than five times by a feather washing machine by adding down feather detergent; the dewatering step includes dewatering until water content of the down feather is lower than 30%; the drying step includes drying the dewatered down feather at the temperature of 120 DEG C by a drying machine or microwaves, and deodorizing and disinfecting; the soaking step includes soaking the down feather in clean water added with natural essential oil; the secondary dewatering and drying step includes dewatering the down feather by a centrifugal machine and drying the dewatered down feather. By the down feather processing production technique, after presorting, dedusting and separating, the down feather is washed, and different kinds of down feathers can be thoroughly cleaned and disinfected; after washing, drying and disinfecting, via secondary soaking in the clean water with natural essential oil, the processed down feather has faint scent and a nerve soothing function.

The invention discloses a down feather cleaning machine, comprising a down feather cleaning device fixedly arranged on a draining pool. The down feather cleaning device comprises a cleaning cavity arranged on a support of the draining pool, the upper part of the cleaning cavity is provided with a discharge opening, a feed opening is communicated with a feed pipe, the lower part of the cleaning cavity is provided with a water outlet, the cleaning cavity is internally provided a rotation shaft rotating under the drive of a driving device, stirring rods are uniformly distributed on the rotation shaft, and the upper part of the cleaning cavity is further provided with a water inlet connected with a water tank on one side of the cleaning cavity. The down feather cleaning machine is characterized in that the upper part of the cleaning cavity is further connected with a feed device. A down feather loosening device is arranged below distribution openings of an outer cavity, the outer cavity is internally provided with a down feather hair loosening device, and the lower part of an air compartment is connected with an oscillating mechanism. The down feather cleaning machine can be used for evenly and smoothly conveying down feathers inside a feed conveying pipeline into processing equipment as required and also can be used for removing impurities and dust inside the down feathers so as to enable the down feather to be cleaner.

A semiconductor device is disclosed that is capable of improving the drain breakdown voltage during operation. The semiconductor device includes a first drain region that is arranged to extend from the vicinity of an end portion of the gate electrode at the drain electrode side in a direction toward the drain electrode, a drain contact region that is formed within the first drain region and comes into contact with the drain electrode, and a second drain region that is formed around and underneath the drain contact region. The second drain contact region has an impurity concentration that is higher than the impurity concentration of the first drain contact region and lower than the impurity concentration of the drain contact region. An end portion of the second drain region at the gate electrode side is positioned away from the end portion of the gate electrode by a predetermined distance.

The present invention relates to a magnetic recording medium comprising a magnetic layer on at least one side of a nonmagnetic substrate, the magnetic layer containing magnetic particles of a CuAu type or Cu₃Au type ferromagnetic ordered phase, wherein a conductive layer is provided on at least one side of the nonmagnetic substrate.

The invention relates to a system for filtering eiderdown threads, in particular to a system for filtering the eiderdown threads based on static by using the static to control the form and the moving direction of the eiderdown threads in an electric field so as to achieve eiderdown thread removal, and belongs to the technical field of eiderdown thread processing. The system uses wind power to fully disperse eiderdown flowers and the eiderdown threads, and utilizes the static to control the form and the moving direction of the eiderdown threads in the electric field so as to accurately separate the eiderdown threads from the eiderdown flowers, achieve filtration of the eiderdown threads through a filter screen, and effectively improve the quality of the eiderdown by using the technique.

The invention relates to a rachis-free feather production process.
