[0018] Preferably, a method for producing a film-coated, anti-drilling, warm down jacket comprises the following steps:

[0019] Step 1: Sew the outer waterproof coating fabric layer, thermal insulation fabric layer, and woven fabric layer, put the processed down feathers into the down bladder layer, seal the opening of the bladder surface fiber fabric layer on the outer wall with a zipper, sew the interior fabric to the outside of the bladder surface fiber fabric layer with the sewing stitches below it, and connect the two sides with vertical Velcro mechanisms;

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The present invention provides a horizontal Velcro mechanism and a vertical Velcro mechanism to achieve a combined effect, so that the down jacket has an opening and can take out the internal down bladder structure. The horizontal belt hook layer improves the sealing effect of the horizontal Velcro mechanism when placed. The outer frame fiber layer and the inner frame fiber layer combine with the horizontal belt hook layer to make the two tighter. The vertical Velcro mechanism is inserted into the horizontal Velcro mechanism through the connecting socket. The outer wall of the insertion end is the fiber surface, and the inner wall is the hook surface, so that the horizontal belt hook layer can be connected and combined with the vertical Velcro mechanism when sealing, and it can simultaneously combine with the inner frame fiber layer and the outer frame fiber layer. The lining is combined to improve its stability. When the inner down bladder needs to be taken out, it is only necessary to tear and separate the horizontal hook layer and the vertical Velcro mechanism. During the tearing process, the interior fabric is driven downward to create an opening for taking out and replacing the inner down bladder. When the down bladder is stuffed, the interior fabric is bonded to the fiber cloth layer on the bladder surface, so that the sealing performance of the two is improved. The vertical Velcro mechanism and the horizontal Velcro mechanism are moved to their original positions to seal. Through the above structure, it is convenient for users to remove the down inside the down jacket and can perform the sealing operation again. The entire removal and sealing process is also more convenient and quick, and the operation can be completed without sewing.

[0025] 2. The rubber plug plays the role of insertion and fixing, so that the down jacket can be reinforced for the second time on the basis of a single Velcro bonding, making the vertical Velcro more difficult to detach. The connecting through-hole is connected to the installation positioning ring mouth for insertion of the rubber plug. The positioning ring is fixed, and the movable ring can be movable. The outer pull head layer and the outer pull strip layer make it convenient for users to move the movable ring. When it moves, the positioning ring can be inserted through the plug-in block to achieve the effect of the combination of the two. After the rubber plug is exposed to the outside, its engaging mouth is combined with the movable ring so that it can be engaged to achieve the positioning effect. BRIEF DESCRIPTION OF THE DRAWINGS
