Duvet and down filling method thereof

Abstract

The invention provides a duvet including a quilt cover. After the quilt cover is symmetrically folded, the quilt cover is sewn together through needles and threads, the four sides of the upper surfaceof the quilt cover and the four sides of the lower surface of the quilt cover are sewn together through needles and threads, and a cavity is formed internally. The cavity is penetrated by needles andthreads from the upper surface of the quilt cover to the lower surface to form a plurality of square compartments, the end sides of the square compartments are provided with down filling ports, and the square compartments are longitudinally communicated through the down filling ports. By arrangement of a double-layer fabric, the down leakage caused by scratching can be effectively avoided, and the service life of the duvet is prolonged. Through the novel down filling method, the down filling can be more uniform, and the down filling efficiency of the duvet is greatly improved.

Description

technical field

[0001] The invention relates to a duvet and a production method thereof, belonging to the field of down processing. Background technique

[0002] The filling of duvets is mainly down, which grows on the abdomen of geese and ducks, and is called feathers in the shape of reed flowers. Because down is a kind of animal protein fiber, it has higher thermal insulation than cotton (vegetable cellulose), and the down ball-shaped fiber is densely covered with tens of thousands of small triangular pores, which can shrink and expand with temperature changes, resulting in a temperature-regulating function. It absorbs the flowing heat from the human body and isolates the invasion of cold air from the outside. Therefore, duvets are widely used as the most insulated quilts. When producing duvets, the quilt surface is usually divided into individual square cells by needlework. Through the blocking effect of the small grid division, the down can be prevented from being displ...
