Embodiment 1

[0031] 1) Add down, water, and detergent into the washing machine to wash the down. Among them, the mass ratio of water to down is 20:1, the washing temperature is 40°C, the mass of detergent added per liter of water is 1g, and it is rotated for 20 minutes.

[0032] 2) Rinse the washed down to remove detergent.

[0033] 3) Adjust the mass ratio of water to rinsed down in the washing machine to 20:1, and after the temperature is 60°C, add softener sulfated castor oil, and adjust the pH value to 4.0 with 0.1g / L formic acid after rotating for 50 minutes. Rotate 30 minutes; Wherein, the quality that adds softening agent sulfated castor oil in every liter of water is 1g;

[0034] 4) Drying, drying, and packaging the down treated in step 3) to obtain down and down with reduced dust.

Embodiment 2

[0036] 1) Add down, water, and detergent into the washing machine to wash the down. Among them, the mass ratio of water to down is 20:1, the washing temperature is 50°C, the mass of detergent added per liter of water is 2g, and it is rotated for 25 minutes.

[0037] 2) Rinse the washed down to remove detergent.

[0038] 3) Adjust the mass ratio of water and rinsed down in the washing machine to 30:1. After the temperature is 60°C, add the softener lanolin succinate sulfonate, and adjust the pH value with 2g / L hydrochloric acid after rotating for 10 minutes. 3.5, rotate for 20 minutes; wherein, the quality of the softening agent lanolin succinate sulfonate added per liter of water is 3g.

[0039] 4) Drying, drying, and packaging the down treated in step 4) to obtain down and down with reduced dust.

Embodiment 3

[0041] 1) Add down, water, and detergent into the washing machine to wash the down. Among them, the mass ratio of water to down is 35:1, the washing temperature is 40°C, the mass of detergent added to each liter of water is 2.5g, and it is rotated for 25 minutes.

[0042] 2) Rinse the washed down to remove detergent.

[0043] 3) Adjust the mass ratio of water in the washing machine to the rinsed down to 20:1, and after the temperature is 50°C, add the softener pentadecylsulfonyl chloride, rotate for 20 minutes, and adjust the pH value to 3.5 with 1g / L sulfuric acid. Rotate for 20 minutes; Wherein, the quality that the softening agent pentadecylsulfonyl chloride is added in every liter of water is 2g.

[0044] 4) Drying, drying, and packaging the down treated in step 3) to obtain down and down with reduced dust.

Abstract

The invention relates to a method for reducing the dust content of down feather. The method comprises the following steps: adding down feather, water and a detergent into a washing machine to wash the down feather; rinsing the washed down feather to remove the detergent; adjusting the mass ratio of the water to the down feather to be (10-40):1 and the temperature to be 20-80 DEG C, then adding a softener into the washing machine, adjusting a pH value to be 3-6 after rotating for 10-60 minutes, and then rotating for 5-30 minutes again; and spinning and drying the down feather to obtain the down feather with reduced dust content. The method does not have special requirements on the quality of the down feather, the softener is applied to the production process of the down feather, and therefore, the dust content of the down feather is reduced, damage to the down feather by high temperature can be reduced during drying simultaneously, the rate of waste of the down feather is reduced, a product can be attached with good hygiene performance, and the added value of the product is increased. By utilizing the method, the down feather can be reduced to three-level low dust or four-level non-dust from one-level high dust content.

Description

technical field [0001] The invention belongs to the field of down processing technology, and in particular relates to a method for reducing the dust content of down. technical background [0002] With the improvement of people's living standards, the demand for down is also increasing, and the quality requirements for down are also getting higher and higher. The dust problem of down is a key factor affecting the quality of down. The current dust removal method for down is physical mechanical dust removal, which will damage the structure of down. In addition, the dust content of down treated by this method is still high, and the dust removal effect is poor. Contents of the invention [0003] The purpose of the present invention is to provide a method for reducing the dust content, so that the down can reduce the dust content of the down while maintaining the original state of lightness, softness and elasticity, so as to achieve the purpose of improving the quality of the do...
