If the down jacket is hairy, you can take it to a professional repair shop for repair. At this time, it is possible that the repair shop will redo the lining. Or if there is a small amount of hair flow, you can tear down the down from the place where you can see it at the seam. Generally, there are only one or two, and basically you won't drill hair again. In addition, it is also possible that the seam of the down jacket is off-line. You can mend the off-line part with the same color needle and thread, so that it will not run out.

The steps of self-treatment are as follows:

Spare materials: scissors, same color needle and thread, lighter.

1, find out the position of running cotton.

2. If it comes from the gap of the thread, just cut the cotton directly.

3. If it is found that the pore of cotton cloth is larger than the diameter of some cotton wool inside, and the cotton wool is separated out, then find out the position of the thread end.

Just sew with the same color thread and needle and thread.

5. After sewing, take a lighter to bake off the extra thread, so that the thread will be stronger.
