Reasons why down jackets are made of velvet:
1. Needle eye velvet: During sewing, the sewing needle and the fabric move at high speed. When the temperature of the sewing needle is too high, it causes the fabric at the needle eye to shrink and harden. The needle eye cannot retract, resulting in a larger needle eye. If the sewing thread is thin, it cannot be fully blocked. The eye of the needle will cause the eye of the needle to become velvet. (You can use sewing thread that is compatible with the fabric and lining to avoid lint from overflowing from the stitching as much as possible)
2. Fabrics and gallbladders: The fabric density is not enough; (Choose fabrics and gallbladders with higher density, and add non-woven fabrics at the suture parts. Non-woven fabrics have better retractability and can prevent needle holes from velvet; choose fabrics and gallbladders with higher density. Sewing thread suitable for fabrics and fabrics)
3. There are a lot of stuffing materials such as wool, feathers and velvet.
4. The northern winter is relatively dry, which easily generates static electricity, which has a certain effect on sucking out down.
The national recommended standard GB/T 14272-2011 determines the anti-drilling properties. If ≤50 qualified products meet the standard requirements.
Advice to consumers:
1. When choosing branded down jackets, there is a certain quality guarantee (branded clothing companies have carried out quality control in the selection of fabrics, linings, gallbladders, down and finished product manufacturing processes to ensure product quality).
2. If there is down accidentally coming out of the seam, please do not pull the down hard, because the better down jackets are made of high-quality down, and the down is larger. If you pull it out with force, more will be pulled. The correct way is to grab the down through the fabric in the opposite direction and pull the down back to the inside of the fabric.
