Problems solved by technology

[0003] The down filling material produced by the existing ordinary technology is easy to be damp, and if it is not dried in time after being damp, it is easy to be attacked by bacteria or produce unpleasant odors, and the fluffy effect of the damp down products will be deteriorated, and the thermal insulation performance will be reduced. Moreover, there is no iron removal process in the whole process, which will greatly affect the comfort of down products

Embodiment Construction

[0018] In this embodiment, a post-processing method for waterproof down is completed through a spray drying integrated machine, a cooling machine and a packaging machine, and the following steps are adopted:

[0019] Step 1) Feathering: add the washed finished down produced by the ordinary process into the hair storage box, vacuum the hair storage box through the fan to make the down pass through the hair storage box, and add iron to remove the iron in the hair storage box Iron removal device, through the quantitative feeding of feathers, the down will pass through the iron removal device;

[0020] Step 2) Spraying: The down treated in step 1) is taken out from the hair storage box, and then fed quantitatively into the spraying device for chemical spraying. The spraying is stirred at the same time, and the spraying pressure is adjusted to 5- 8 kg / cm 2 , the spray time is 15-20min, and continue to stir for 15min after spraying;

[0021] The ratio of the agent: based on the gr...

Abstract

The invention discloses an aftertreatment processing method for waterproof down. The method comprises steps as follows: step 1), down addition: a washed finished down product is added to a down storage box, and down is enabled to pass an iron removing device through quantitative feeding; step 2), spraying: the down is extracted from the down storage box, chemical spraying is performed through thequantitative feeding, and stirring is performed during spraying; step 3), dehumidification and sizing: the down enters a dehumidification stage after being stirred, and excessive water in a spraying device is dried by a fan; step 4), drying: the down is sucked into an oil heat conduction drying device by the fan and is dried through the quantitative feeding; step 5), cooling and dedusting; step 6), secondary cooling; step 7), down discharge and packaging. According to the scheme, the down subjected to waterproof treatment is provided with a protecting nanofilm and has excellent waterproof performance, filling power is improved, and heat retention property of the down is improved; besides, the down has certain dampproof and antibacterial functions, and is protected from breeding bacteria and producing peculiar smell due to dampness.

Description

technical field [0001] The invention belongs to the field of down processing, and in particular relates to a post-processing method for waterproof down. Background technique [0002] The natural special structure of down makes down the best thermal insulation material in the world. But once the down is wet, it is difficult to dry, and it completely loses its function of keeping warm. In harsh and cold environments, waterproof down products prevent the down from losing its heat preservation function due to wet water due to its excellent waterproof performance and thermal insulation performance, and provide certain safety protection for outdoor personnel. And in daily use, waterproof down products can be washed in a washing machine, and dry quickly after washing, and the drying time is 75% shorter than that of ordinary down. Energy saving. The production process of the existing common down filling material is to firstly carry out dust removal and ash removal on the down raw...
