1. When manufacturing the filling material of the non-stuffy and odorless large down mountaineering down jacket, we use a set of scientific and precise technologies and process flows, and are committed to creating high-quality, high-performance warmth products for consumers.
2. The initial stage is the rough filtration of debris. With the help of special rough filtration equipment, the larger volume of debris mixed in the velvet source is quickly intercepted and separated. This operation quickly purifies the velvet source and paves the way for subsequent fine processing. The next step is the dust purification stage. The efficient dust collection device is used to comprehensively vacuum the velvet source after rough filtration to ensure that the fine dust in it is nowhere to be found, so that the velvet source initially meets the basic requirements of cleaning.
3. The subsequent down sorting is the key node of the whole process. The advanced intelligent sorting system is used to accurately separate the dust-purified down source into large down, feather pieces of different sizes and various wing stems according to the unique physical characteristics of large down, creating conditions for subsequent targeted deep processing. After the sorting is completed, the deep down cleaning step is entered. A specially developed environmentally friendly down cleaning agent is added to the professional down cleaning equipment to perform a comprehensive and deep cleaning of the down source. This cleaning agent can strongly disintegrate and remove the grease and dust attached to the down source, while effectively decomposing and eliminating odors, allowing the large down to return to its natural and pure state, laying the foundation for achieving the goal of no stuffiness and no odor.
4. The washed wool source then enters the rapid dehydration process. With the help of high-speed rotating dehydration equipment, most of the water in the wool source is quickly thrown out, greatly reducing the time and energy consumption required for subsequent drying. The dehydrated wool source then enters the professional wool drying equipment for deep drying. This process can not only completely evaporate the residual water, but also simultaneously achieve efficient deodorization and comprehensive disinfection, fundamentally guaranteeing the quality and sanitary safety of the wool source. After the wool is dried, the cooling equipment is used to quickly cool the wool source. During this process, the fine filtering device inside the equipment can capture and remove any fine impurities that may remain, further improving the cleanliness of the wool source and ensuring that each large wool is pure and flawless.
5. Product quality testing is the core link to ensure the quality of Daduo velvet. For all kinds of velvet products after drying, we strictly follow the high standard quality specifications to conduct meticulous testing, and any details that may affect the performance and quality of the product will not be missed. Finally, for the Daduo velvet that has passed the inspection, we use professional packaging machinery to accurately classify and package according to different varieties and specifications, and then properly pack and store them in a constant temperature and humidity environment.
