High Down Content, Zero Pressure, Zero Odor, Antibacterial And Anti-Mite, Thick Winter Duvet Filling

It is mainly suitable for winter thick down quilts made of textile woven fabrics as the main fabric. In terms of filling composition, the main part of the quilt core, such as the large area of ​​the quilt cover and other key parts, must be filled with this high-quality down to ensure the high-quality warmth and various characteristics of the product. However, for relatively small parts such as quilt corners and hemming, other fillings are allowed on the premise of complying with the national mandatory standard GB 18383-2007 "General Technical Requirements for Wadding Fiber Products". ​ From the perspective of application scenarios, for infant winter thick down quilts made by weaving technology, you can rest assured to use this filling material and produce it in accordance with relevant standards. However, it should be noted that if it is a winter thick down quilt for infants and young children made by knitting technology, the selection of its filling material and product standards should refer to FZ/T 73025-2019 "Infant Knitted Clothing", and FZ/T 73053-2015 "Knitted Down Clothing" does not apply to infant-related products, and naturally does not apply to the application of this filling material in infant winter thick down quilts made by this process.​ It should be pointed out in particular that this filling material is not suitable for thick winter duvets that use down and fiber as a blended filling, layered filling, or partitioned fiber filling. At present, there is no corresponding national standard or industry standard for the blended filling of down and other fibers. If an enterprise has such special needs, it can formulate its own enterprise standard based on its actual situation.

In terms of warmth, the hollow structure of down fiber can store a large amount of still air, forming an efficient thermal insulation layer, bringing an extraordinary warmth experience. It is extremely light and soft, with a light texture and delicate touch. There is no sense of oppression when sleeping, and it is easy and convenient to store and carry. It has excellent fluffy performance. After long-term use and frequent folding, it can rebound quickly and always maintain a full state. It is beautiful and practical. It performs well in moisture absorption and perspiration, and can quickly absorb human body moisture and discharge it to keep the quilt dry. Through special processing, it has antibacterial and anti-mite functions to protect the healthy sleeping environment. Whether it is a cold winter day or a season with changeable temperature, it can adapt with good warmth retention. It is of high quality and durability. It can be used for a long time with proper maintenance and is cost-effective. ​

1. Preliminary screening and impurity removal: A specially customized pre-sorting device is used. The device is equipped with a high-precision identification sensor, which can keenly detect and quickly remove various large pieces of debris such as grass stems and branches mixed in the down raw materials, greatly improving the purity of the down raw materials and laying a solid foundation for subsequent processing. ​

2. Deep vacuuming: Professional-grade vacuum cleaning equipment is used to clean the down after the initial screening with strong suction in all directions to ensure that all fine dust is removed, so that the down initially meets the cleaning standards, creating a good start for subsequent refined processing. ​

3. Accurate down quality classification: Using advanced intelligent identification and separation systems, based on the unique physical characteristics of down, such as the fluffiness of the down, the size difference of the hair pieces, and the morphological characteristics of the wing stems, the down that has been vacuumed is accurately divided into down, large, medium and small hair pieces of different specifications, and various wing stems, creating favorable conditions for subsequent targeted deep processing. ​

4. Deep purification: In the special cleaning device, the self-developed environmentally friendly and efficient down cleaning agent is injected. The detergent can strongly dissolve and remove grease and stubborn stains attached to the surface of down, while effectively decomposing and eliminating odors, restoring the natural and pure texture of down in all directions, and laying a solid foundation for achieving the goal of zero odor. ​

5. Efficient dehydration: With the help of high-speed centrifugal dehydration equipment, a large amount of water in the washed down can be quickly thrown out in a short time, greatly shortening the time and energy consumption required for subsequent drying. ​

6. Deep drying: The dehydrated down is transferred to a professional down drying equipment for deep drying. This process can not only completely evaporate the residual water, but also use advanced deodorization and disinfection technology to ensure the quality and hygiene of the down from the source, ensuring that every strand of down is clean and sterile. ​

7. Intelligent cooling: Use the intelligent cooling system to quickly cool down the down after drying. During the cooling process, the fine filter components inside the equipment can capture and remove the fine impurities that may remain again, further improving the cleanliness of the down and ensuring that every piece of down is pure and flawless.​

8. Antibacterial and anti-mite treatment: Using cutting-edge nanotechnology, specially developed antibacterial and anti-mite nanoparticles are evenly attached to the surface of down fibers, giving the down long-lasting antibacterial and anti-mite properties without affecting the softness and warmth of the down, creating a healthy and comfortable sleeping environment for users. ​

9. Product quality testing: For all types of down products that have completed antibacterial and anti-mite treatment, we strictly refer to ultra-high standard quality specifications for detailed testing, and do not miss any details that may affect product performance and quality.
