Problems solved by technology

However, when it comes to drill down, it is the most common problem, some are seriously drilled, and a lot of feathers will be attached to the body every time they are taken off, and even the down will come out during the wearing process, which will affect the image of the wearer
[0003] In the traditional production process, the surface is covered with the fleece cloth and the board around the lining. After filling the fleece and patting them evenly, they are lined together according to the positioning line. After this method, it is...

According to the down-proof sewing technology, elastic cotton polyester yarn is adopted as fabric quilting threads for sewing, in the sewing process, garment pieces are kept in a tight state, the fabric quilting threads are kept in a stretched state, and after down feather is filled, the garment pieces are taken down and subjected to standing so that the fabric quilting threads can be retracted; after the cotton polyester yarn fabric is retracted, the yarn body expands and the seam holes become smaller, so that down flowers are not easy to drill out of the seam holes, and the practicability of the fabric after being sewn can be improved.

Example Embodiment

[0022] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.
[0023] Example;
[0024] refer to Figure 1 to Figure 2 , an anti-drill down sewing process, comprising the following steps:
[0025] S11, prepare materials, select fabrics, cut the selected fabrics into an upper fabric layer and a lower fabric layer according to a predetermined template, and select elastic cotton and polyester yarns as fabric yarns.
[0026] S12, clamping, overlapping the upper fabric layer and the lower fabric layer to form a garment piece 1, and clamping it along the edge of the garment piece 1 with a clamp.
[0027] S13, stretch the suture, tighten the garment piece 1 after clamping, pass the taut garment piece 1 through the template to keep it in a taut state and clamp it on the template machine, and then stretch the fabric to traverse the thread , so that the length of the fabric line is extended to 1.05-1.20 times the original length, and then the fabric line is sewn according to the preset line pattern to form a packing cavity; The line graph is easier to sew on the garment piece 1.
[0028] S14, running edge sewing, the garment piece 1 in a taut state is then run edge sewing according to the pie chart, and a velvet filling opening is reserved;
[0029] S15, filling down, continuing to keep the garment piece 1 in a taut state, filling down in the packaging cavity through the down filling opening according to a predetermined down filling amount, and then using the fabric yarn as described Diffuser figure 2 Sew, and then rewind according to the preset figure 2 The fleece-filling opening is run-edge sewing, and the fleece-filling opening is sealed to complete the preparation of the garment piece 1 .
[0030] S16, stand and retract, and remove the garment piece 1 from the template, so that the garment piece 1 is no longer taut. After sewing the fabric yarn and after removing the garment piece 1, the fabric yarn will Retraction occurs gradually, so the clothing piece 1 is laid down and placed until the fabric winding is completely retracted, and the standing time is not less than 12 hours. When the clothing piece 1 is left standing, the fabric winding will gradually shrink. The gap between the seam holes is also reduced, which can prevent the down from drilling out of the seam holes, thereby improving the practical performance of the fabric.
[0031] S17 , trim the remaining edges, after the standing and retraction is completed, trim the garment piece 1 , and trim off the excess fabric at the edge of the garment piece 1 .
[0032] In step S15, the material of the down is 90% white duck down with a bulkiness greater than 600 or 95% gray goose down with a bulkiness greater than 800.
[0033] In steps S13 and S15, 11-13 needles/3cm open stitches and 12-14 needles/3cm dark stitches are used for sewing, and 11-gauge needles are required.
[0034] A first transition area 3 with a width of 1cm-1.5cm is set between the edge of the upper fabric layer and the traverse line, and a 0.5 cm width is set between the edge of the lower layer fabric layer and the sewn fabric traverse line. For the second transition area 4 with a width of cm-1 cm, in step S17, when trimming, the upper fabric layer is kept trimmed along the edge line of the first transition area 3, and the lower fabric layer is kept along the second transition area 4 Edge trimming, the garment piece 1 includes a front garment piece 1 and a rear garment piece 1, and the front garment piece 1 and the rear garment piece 1 are stitched together by a patchwork process or a lockstitch process. Sewing with the rear garment part 1 to form a garment body, the front garment part 1 and the rear garment part 1 are sewn along the first transition area 3 and the second transition area 4 rows of needles during sewing, When the front part 1 and the rear part 1 are sewn to each other to form the body, the first transition area 3 and the second transition area 4 are used to sew and connect, so as to prevent the connection of down from the front part 1 to the rear part 1 Drill out.
[0035] The above records are only examples of utilizing the technical content of this creation, and any modifications and changes made by those skilled in the art using this creation are all within the scope of the patent claimed in this creation, and are not limited to those disclosed in the embodiments.
