Down quilt with good down locking effect and down filling method thereof

Abstract

The invention provides a down quilt with a good down locking effect. An inner cavity is formed in an upper quilt cover and a lower quilt cover. The inner cavity is penetrated by needles and threads from the upper quilt surface to the lower quilt surface to form a plurality of first compartments. A first down filling opening is formed in the end side of each first compartment. The first compartments are communicated with one another through a down filling bag. The down filling bag comprises upper supporting cloth and lower supporting cloth. The upper supporting cloth and the lower supporting cloth are bonded to the inner wall of the inner cavity through a hot melt adhesive. The upper supporting cloth and the lower supporting cloth are both hard U-shaped cloth. The two sides of the upper supporting cloth and the two sides of the lower supporting cloth are bonded through the hot melt adhesive. A down filling channel is defined by the upper supporting cloth and the lower supporting cloth.A plurality of pieces of swingable blocking cloth are bonded to the inner upper wall of the down filling channel through the hot melt adhesive. The invention further provides a down filling method ofthe down quilt with the good down locking effect. According to the invention, the down locking effect of the down quilt can be effectively improved. The down in the down quilt is prevented from movingdisorderly. The down in the down quilt is evenly distributed. The down filling efficiency and the down filling quality are effectively improved.

Description

technical field [0001] The invention relates to the technical field of production of down quilts, in particular to a down quilt with good down locking effect and a down filling method thereof. Background technique [0002] At present, the structure of the duvet mainly includes two kinds, one is to divide the inner hole space of the duvet into a plurality of parallel long strip lattices running through the inner hole of the duvet by sewing on the duvet, and the other is to separate the inner hole space of the duvet into a plurality of parallel grids through the inner hole of the duvet; The inner hole of the duvet is divided into a plurality of horizontal and vertical square grids, and openings are reserved between the square grids for the entry and exit of the down filling tubes. The duvet can prevent the down from moving to other positions through the separation and blocking effect of the grid, preventing some positions from having no down and some positions from having too ...

AI Technical Summary

Problems solved by technology

According to the internal structure of the existing down quilt, when filling down, it is necessary to penetrate the down filling tube into the down quilt and then transmit the down through the channels between each square. After filling the down, these channels are still connected, which causes the down The down is easy to run around when being used, resulting in uneven distribution of down in the actual use of the duvet, which affects the actual use, and according to the internal structure of the existing duvet, it is necessary to extend the down filling tube into the duvet many times when filling the down. This has resulted in a reduction in the filling efficiency of the duvet, which cannot meet the needs of actual production. Therefore, it is urgent to develop a down filling method with a good down-locking effect and a high down-filling efficiency to solve the problems in the prior art.
