Down-leakage-proof down product and production method of down product

Abstract

The invention discloses a down-leakage-proof down product and a production method of the down product. The down product comprises a shell fabric, a lining fabric, down and a layer of down-proof medium. The down is filled between the shell fabric and the lining fabric, the down-proof medium clings to the inner surface of the shell fabric or the inner surface of the lining fabric, and ultrasonic-wave quilted seams or glued hot-press quilted seams are performed between the shell fabric and the lining fabric. As the air-moisture permeable down-proof medium is combined with the lining fabric or the shell fabric in a press fit way and the down-proof medium is high in density, the down-leakage problem caused by a low fabric density and sewing needle holes can be effectively solved.

Description

Technical field [0001] The invention relates to a garment, in particular to a leak-proof down down product and a production method thereof. Background technique [0002] Down products are made of double-layer fabrics and sewing threads to make the inner liner of the clothes at intervals, and then stuffing (down) is stuffed into the inner liner, and this liner is sewn to the outer shell of the garment (or quilt). Form products such as down jackets or duvets. This kind of product has several disadvantages: 1. Down will leak out from the needle hole of the product; 2. If the fabric used is low density, down will also leak out. Down often falling out will affect the quality of the product. In order to prevent the down from leaking, down products are often made of woven fabrics with high density or back glue, resulting in poor air permeability and a sense of stuffiness on the market. And the accumulation of static electricity causes various troubles, and the fabric used is single, a...

AI Technical Summary

Problems solved by technology

The down often falls out, which will affect the quality of the product. In order to prevent the down from leaking out, down products are often made of woven fabrics with high density or adhesive backing. As a result, the down products on the market have poor air permeability and feel stuffy. And static electricity accumulation causes all kinds of troubles, and the fabric used is single, and the style is not beautiful enough

3. The traditional sewing process is prone to problems such as wrinkles in the sewing part, needle eating, skew twisting, broken needles, and thread jumping

[0004] The technologies adopted in the above-mentioned patents are all glued or glued on the sewing line, which can only solve the first point of the problem of running velvet on the sewing line, but cannot solve the problem of running velvet on the face cloth.
