Embodiment 1

[0026] The present embodiment measures down bulkiness according to the following steps:

[0027] (1) Sample processing

[0028] Put 5.0g of 1# down sample to be tested in an oven, and dry it at 70°C for 45 minutes; then shake the down sample to be tested into the pre-treatment box to make it fluffy, and then dry it at a temperature of 70°C and a relative humidity of 65°C. 24h recovery in % of the environment;

[0029] (2) Thickness measurement

[0030] Spread 1.0g of the treated down sample to be tested evenly in a ziplock bag with a size of 8cm×12cm, exhaust the air in the bag, and seal the bag mouth; randomly select 6 positions on the ziplock bag, and use a thickness meter to measure the thickness of each selected area. The thickness at this time (respectively 1.11cm, 1.00cm, 1.13cm, 1.18cm, 1.19cm, 1.17cm), and then calculate the average value of the thickness of the 6 places is 1.13cm, as the minimum thickness T of the down to be tested 0 ;

[0031] Let the ziplock bag...

Embodiment 2

[0036] The present embodiment measures down bulkiness according to the following steps:

[0037] (1) Sample processing

[0038] Put 5.0g of the 2# down sample to be tested in an oven, and dry it at 70°C for 45 minutes; then shake the down sample to be tested into the pre-treatment box to make it fluffy, and then dry it at a temperature of 70°C and a relative humidity of 65°C. 24h recovery in % of the environment;

[0039] (2) Thickness measurement

[0040] Spread 1.0g of the treated down sample to be tested evenly in a ziplock bag with a size of 8cm×12cm, exhaust the air in the bag, and seal the bag mouth; randomly select 6 positions on the ziplock bag, and use a thickness meter to measure the thickness of each selected area. The thickness at this time (respectively 1.31cm, 1.37cm, 1.24cm, 1.28cm, 1.26cm, 1.25cm), and then calculate the average value of 1.29cm of the thickness of the 6 places, as the minimum thickness T of the down to be tested 0 ;

[0041] Leave the ziplo...

Embodiment 3

[0046] The present embodiment measures down bulkiness according to the following steps:

[0047] (1) Sample processing

[0048] Put 5.0g of 3# down sample to be tested in an oven, and dry it at 70°C for 45 minutes; then shake the down sample to be tested into the pre-treatment box to make it fluffy, and then dry it at a temperature of 70°C and a relative humidity of 65°C. 24h recovery in % of the environment;

[0049] (2) Thickness measurement

[0050] Spread 1.0g of the treated down sample to be tested evenly in a ziplock bag with a size of 8cm×12cm, exhaust the air in the bag, and seal the bag mouth; randomly select 6 positions on the ziplock bag, and use a thickness meter to measure the thickness of each selected area. The thickness at this time (respectively 1.09cm, 1.07cm, 1.04cm, 1.08cm, 1.07cm, 1.01cm), and then calculate the average value of 1.06cm of the thickness of the 6 places, as the minimum thickness T of the down to be tested 0 ;

Abstract

The invention discloses a simple testing method for filling power of bag type down feather. The simple testing method is characterized by after carrying out pretreatment on to-be-tested down feather, uniformly and flatly paving the down feather in a self sealing bag, exhausting air in the bag and sealing, testing the thickness at the moment through a thickness instrument, testing the thickness again after standing until the down feather gets fluffy, and calculating the filling power of the down feather through the thickness difference of twice testing. According to the simple testing method disclosed by the invention, testing can be completed just through the thickness instrument and the self sealing bag, the method is simple, the instrument is small in size, the carrying is convenient, the needed down feather amount is small, and the materials are saved.

Description

technical field [0001] The invention relates to a method for testing down properties, in particular to a method for measuring the bulkiness of down. Background technique [0002] China is the world's largest exporter and consumer of down garments, down bedding and other down products. In recent years, the United States has dominated China's largest down export market. Because down products are soft, fluffy, easy to wash, cheap and high-quality, and have strong warmth retention properties, they have always been the main force in the cold-proof product market. [0003] Bulkiness is one of the important indicators to test the quality of down. It directly reflects the warmth retention of down products, and indirectly reflects the degree of dispersion among the components of down. Bulkiness testing is one of the important contents of down performance testing. The higher the bulkiness, it means that the same quality down can fix a larger volume of air layer to keep warm and ins...
