Description

Technical Field

[0001] The utility model relates to a back patch pocket of clothing, in particular to a pair of trousers with a back patch pocket which is resistant to being pulled apart. Background Art

[0002] The back patch pockets on jeans and casual trousers are mainly used to lift and decorate the buttocks. At the same time, the back pockets can also be used to hold hands and store things. Designers often use the size, style and decoration of the back patch pockets to improve their designs or use industrial washing and other processes to make the buttocks more prominent, making the style more casual and natural and the art more perfect.

[0003] The back pocket fabric is sewn directly against the trouser body. The pocket patch and the fabric are pierced with sewing needles and the pocket corners are positioned. When consumers wear the trousers, the force points on the trouser fabric are concentrated at a single point on the pocket corner sewing line, and the force direction is vertically downward. When the back pocket corners and the trouser body are subjected to a certain external force, the back pocket will be torn and the strength will decrease, thereby damaging the entire back trouser piece.

[0004] Chinese patent CN205197036U discloses a pair of trousers designed to prevent back pocket tearing, comprising a head fabric, patch pockets, a back panel, and a back pocket tear prevention mechanism. The use of a head lining strengthens the stress-bearing area of the back pocket, increasing the strength of the fabric at this stress-bearing area and preventing fabric tearing. However, the head lining design results in a large and wide lining fabric, which has little practical use and is wasteful. Furthermore, it increases the thickness of the fabric, making it less comfortable and breathable.

[0005] The old design of the back patch pocket paper pattern has a 1.2cm stop and a double solid line pressed 0.6cm inside the surface; the folded seam of the 1.2cm stop is 0.6cm inside the line. The double-layer fabric folded in half will form a stock position. The corner of the back patch pocket at the stock position is relatively hard, which can easily generate relatively concentrated vertical external force during washing and wearing, causing damage to the fabric fibers and tearing and breaking.

[0021] Compare with the original sample: the back patch pocket paper pattern has a 1.2cm wide seam allowance, the bag edge and the folded stop line are parallel to the 0.6cm wide internal pressure double solid line on the surface; after the stop is folded in half, the bag edge is 0.6cm close to the internal pressure double solid line seam position within the running line, and the double-layer fabric folded in half will form a stock position. Example

[0022] This embodiment is based on Figure 1-4 Provided are trousers with tear-resistant back patch pockets. The trousers comprise a trouser body fabric and a back patch pocket. The back patch pocket is sewn onto the trouser body fabric by stitching, wherein the stitching comprises an inner pressure double solid line, a back patch pocket positioning line and a stitching line. A back pocket lining is also provided on the inner side of the trouser body.

[0023] Before sewing the back patch pocket, confirm the seam allowance and stop position. The intersection of the left and right sides of the back patch pocket and the bottom is the top angle. The side stop line is angled 5-10 degrees inward and 1.2 cm inward, forming the fold stop line. Therefore, the side stop line and the side of the back patch pocket are non-parallel at a certain angle. When the side is at the bottom, the distance from the stop line is 1.2 cm. When the side is at the top opening, the distance from the stop line is 2.0 cm. The edges of the top opening and bottom are parallel to the fold stop line, and the seam allowance between the side and the stop line is always 1.2 cm.

[0024] After the stop is folded, the back patch pocket, the back patch pocket seam and the trouser body are sewn together by the inner pressure double solid line. The inner pressure double solid line is 0.2cm away from the stop line and the line width is 0.6cm. Among them, because the bag side stop line and the bag side bag edge present a certain angle, after folding, there will be a seam exposed in the inner pressure double solid line sewing. Among them, after the seam is folded, the fabric thickness accounts for 0.2cm, the inner pressure double solid line accounts for 0.8cm, and the raw edge accounts for 0.2cm. Therefore, the exposed part of the 2.0cm seam will have an additional exposed part of 0.8cm at the upper pocket, and because of the angle, the exposed part of the seam is as follows. Figure 4 Shown as a triangle.

[0025] After sewing the double solid line of internal pressure, a tie line is set at the upper end of the back patch pocket and the folded positions on the left and right sides. The tie line is sewn horizontally on the double solid line of internal pressure at the corner of the bag, and the length of the tie line is 0.8 cm.

[0026] A 2.0cm back pocket positioning line is sewn perpendicular to the stitching line on the exposed part of the seam inside the back pocket. The 0.8cm positioning line can participate in the single-point force of the stressed fabric at the seam, so that the point force is extended to the 0-0.8cm wide line force, so that the single-layer fabric of the trouser body that was originally subjected to single-point force is changed to a double-layer fabric of the trouser body fabric and the exposed part of the seam that are subjected to force at the same time. Therefore, the force area and force direction at the fabric seam are improved, and the damage to the fabric caused by the vertical force between the back pocket corner and the trouser body fabric is reduced.

[0027] The trouser body also features a circular back pocket lining, which is sewn together with a tassel thread. The tassel thread is sewn within the diameter of the circular back pocket lining, which ranges from 1.0 to 1.5 cm. This design increases the yarn's load-bearing area and strengthens the seam.

[0028] The three sides of the back patch pocket have a lock edge structure, which is obtained by lock edge processing. The three sides include the two sides of the bag and the bag bottom. The lock edge width is 0.4cm or 0.6cm. The bag bottom can be a variety of shapes according to the design, such as square, diamond and arc. For example, in this embodiment Figure 4 The diamond shape shown in the figure. The lock edge structure can prevent the exposed parts of the back patch pocket from raveling during washing.

[0029] Through this process adjustment, the strength of the back pocket corner seam of the original process is 61N. In the comparative test, based on the same fabric and unchanged appearance of the back patch pocket, the tearing strength of the back pocket corner is increased by 60N-160N. After the production process is adjusted in this embodiment, the strength of the back pocket corner seam is 135N and is not damaged after fermentation washing.

[0030] It should be noted that the above is only a preferred embodiment of the present invention, and the illustrations and sizes in the drawings of the specification are only examples and are not used to limit the present invention. Any non-creative changes and additions made by those skilled in the art on the basis of the present invention should fall within the scope of protection of the present invention.
