Fluffiness Definition of Feather Down

As one of the most important quality indexes of feather and down, fluffiness index is the concentrated embodiment of elasticity and warmth. Fluffiness is an important part of down test, and it is evaluated by measuring the volume of a certain number down sample inside a certain caliber container under a certain pressure. The greater the fluffy, the greater the amount of static air contained, and the static air layer is a good insulation layer, so the greater the fluffiness of down, the better the warmth of down products.

Influencing Factors of the Feather & Down Fluffiness

Whether feather down can return to its best initial state is directly related to the final test results of fluffiness during the testing process. All of the following factors affect the final test results:

Sampling methods for testing tests, initial state reduction methods for feather and down (oven reduction method, steam reduction method, etc.), the effects of temperature and humidity in a laboratory, test method and evaluation standard for fluffiness of down, and the effect of test equipment and personnel operation.

Feather and Down Fluffiness Tester

Automatic feather & down fluffiness tester produced by our company is suitable for the fluffiness test of feather down and other fillers. It meets a variety of test standards. The main features are as follows:

1 The machine uses color touch-screen display and is easy to operate.

2 Unique filtration ventilation design, automatic switching of pile down and suction position to ensure that feathers will not fly in disorder and prevent operators from being harming.

3 The test speed can be set up, suitable for different standards, and the transmission structure adopts servo motor system, so that the height accuracy of bulkiness is more precise.

4 The original zero position system ensures the correctness of the data.

5 Using high precision sensor, ARM32 bit microprocessor, 16 bit A/D of AD company to collect Xingping, accurately sensing the position of pressure plate, accurate calculation of the test results, can apply a number of standards.

6 The automatic wind speed design system ensures that the down feather is in a state of natural fluffy, so that each measurement data has good authenticity and reproducibility.

7 The test process is completed by one button, and the test bucket is not replaced manually.

8 Automatic test, no need to manually replace the test bucket.

Test Method for Fluffiness of Down

At present, The existing test standards for bulkiness are: GB/T10288 (feather and down test method), FZ/T80001 (washed feather & down test method), BSEN12130 (feather down test method-fluffiness measurement), JISL1903 (feather down test method), and IDFB (official analysis method of international feather down bureau).

Here take the IDFB (official analysis method of international feather down bureau) as an example, introduce the brief operation process.

Treat the samples with oven reduction method, steam reduction method. After treatment, put 30g samples into the measuring barrel and blown loose for 5s with the blast equipment. It needs to be blown twice before the first test, and one blow before the next four tests. When press the start button, the weight plate moves down at a predetermined speed (0.54m/min). When the pressure plate comes into contact with the sample in the measuring tube, the decreasing speed of the pressure plate is reduced to less than 0.3m/min due to the reaction force of the sample. At the same time, the test values are continuously displayed after the loading time 1min and the test values are printed out. Test the samples five times and calculate the final results.
