TECHNICAL FIELD
[0001] The application relates to the field of down jacket processing technology, in particular to a down jacket sewing position anti-down-running structure. BACKGROUND
[0002] Down jackets have become indispensable clothing for people in winter today. With the normalization of down jackets, people's quality requirements for down jackets are also getting higher and higher. With the improvement of technology, the quality of down jackets has been significantly improved compared with the past.
[0003] In the production process of the down jacket, the upper layer and the lower layer of the down jacket need to be sewn to form a down filling bag, so as to form a heat preservation layer of the down jacket. However, the down material is easy to escape from the sewing gap at the edge of the filling bag to the outside or the adjacent filling bag, resulting in the phenomenon of down running or uneven distribution of down. Therefore, the designer sets a barrier strip at the edge of the filling bag to prevent the down material from reaching the sewing position. At the same time, the narrow gap between the barrier strip and the fabric is difficult for the down material to enter, and the movement ability of the down material is also hindered, thereby improving the anti-down-running ability of the down jacket. However, the general sewing device is difficult to fix such a down jacket structure, and the problem of deviation from the designed sewing path is easy to occur during the sewing process, which is not conducive to the use of the user.
