Down jacket with double-layer down locking structure

Abstract

The invention relates to a down jacket with a double-layer down locking structure, which is characterized in that second down is filled between a primary down locking layer and a secondary down locking layer, when the second down is processed, a part of the second down enters an arc-shaped groove and fills the inner space of the arc-shaped groove, and at the moment, the second down is fixedly sealed in the arc-shaped groove; the grabbing and attaching fibers are located at the openings of the arc-shaped grooves, the uniformity of the heat preservation performance of the primary down locking layer can be effectively guaranteed, meanwhile, by simulating the dandelion seed fixing situation, the roots of primary down feather are attached to the interiors of the air holes, down feather fibers of the primary down feather are clamped in the cracking parts, and the heat preservation performance of the primary down feather layer is improved. The primary down feathers which are distributed in a crossed mode and evenly located in the cracking parts can form a protective layer of a down-shaped net structure at the secondary down locking layer, on one hand, the primary down feathers located in the rhombic inner container are not prone to penetrating through the protective layer, and the down-proof effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of down jackets, and in particular relates to a down jacket with a double-layer lock down structure. Background technique [0002] Down jackets are filled with down fillers, with a large and round shape; down jackets generally account for more than half of duck down, and some fine feathers can be mixed at the same time. The duck down is cleaned, sterilized at high temperature, and then filled in the clothes to be down jackets; down jackets are the most warm. it is good. It is mostly worn by people in cold regions, and is also commonly used by polar expedition personnel. [0003] Among them, down is a mixture of "feather" and "down". Feather is the hair piece, which plays a supporting role in the down and can make the down quickly rebound; and the down is the down bud, which is the body and value of the down. The velvet flower is a three-dimensional spherical shape, which is composed of a velvet core and m...

Problems solved by technology

[0004] And the existing down jacket adopts double-layer fabrics to seal the down in the liner, but due to the need to satisfy the air permeability of the down jacket, the holes of the fabric will increase. There are holes in the liner, and with the circulation of the air in the liner, the down is easy to float out along the holes, resulting in a great reduction in the down content in the liner. Uneven distribution leads to poor local warmth retention of the down jacket, and poor ductility of the down jacket, which is prone to scratches, causing damage to the down jacket fabric, and the down is easy to float out
