Down fabric processing is the production of poultry feathers after decontamination, washing, disinfection and other processes, filled into the fabric, the use of sewing technology to sew down and fabric together, to make warm down jacket and other products. In this process, the quality of the fabric and processing technology are crucial. Let's take a closer look at the down fabric processing steps and precautions.
1. Collection of raw materials
Down fabric processing is first of all to collect raw materials, that is, to collect poultry feathers. Good down fabrics need to choose high-quality down, so pay attention to many details when collecting. First of all, choose feathers that are relatively short of the bird's death time, usually less than 6 hours after the bird's death to collect feathers; Secondly, it is necessary to avoid the dust and stains collected in the feathers, which need to be removed by the subsequent treatment process.
2. Decontamination and disinfection
Collected feathers can carry a lot of stains and bacteria, so they need to be decontaminated and disinfected first. Usually the method of washing is used, which is soaked in water for a period of time, and then washed repeatedly with clean water until the water is no longer gray. In order to eliminate bacteria, it is also necessary to add some disinfectant during the process of washing.
Third, drying and separation
After decontamination and disinfection, the feathers need to be dried to avoid mold and odor. Low temperature drying can be used, but care needs to be taken to control the temperature and time to avoid damaging the elasticity and softness of the feathers. After drying, the feathers need to be separated and feathers of similar size, length and quality are separated together for subsequent processing.
Four, the production of down fabric
In the process of making down fabrics, high-quality and dense fabrics need to be selected to ensure that feathers will not drift freely after filling into the fabric, and it is also necessary to pay attention to the fastness and softness of the fabric. In order to improve the effect of down filling, you can add dense fluff to the fabric to make it a more fluffy filling.
Five, fill down
The key point to pay attention to in the filling process is: to fill fully, but not to fill too much. Too little filling will lead to poor warmth, and too much filling will affect air permeability and comfort. Therefore, when filling, the size, thickness and weight of the fabric need to be carefully measured and calculated to ensure that the amount of filling is moderate.
6. Suture
After the filling is complete, it is also necessary to sew the fabric and the filler together firmly using the sewing process. In this process, it is necessary to pay attention to the material and fastness of the thread and the type and length of the needle. Choosing the right sewing technology can improve production efficiency while ensuring quality.
Vii. Inspection and packaging
Finally, it is inspected and properly packed. When testing, it is necessary to pay attention to the problems of taste, appearance, weight and so on. When packaging, compression packaging or vacuum compression packaging can be used to save storage and transportation space.
In short, down fabric processing is a technology-intensive production process, only master the correct technology and processing methods, can produce high-quality down fabric products.
