DETAILED DESCRIPTION

[0017] In the following description, a large number of specific details are provided to provide a more thorough understanding of the present invention. However, it is apparent to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some technical features well known in the art are not described.

[0018] The applicant believes that the existing technology has problems such as uneven singeing effect, high energy consumption, and large equipment footprint, which not only affects production efficiency but also may cause damage to the fabric.

[0019] To this end, the applicant designed a shirt pattern process for improving back comfort, comprising the following steps: S1: Pattern making and cutting, including front piece, back piece, sleeves and collar; S2: color fixing, softening, cleaning, drying, cleaning and drying the cut pieces; S3: Sewing, using blind stitching technology to sew the front piece, back piece, sleeves and collar together, and tighten the narrow front piece seam allowance and loosen the back piece seam allowance when sewing; S4: Wash, dry, iron and set.

[0020] In step S1, when making the back plate, Figure 2 As shown, increase the width of the back piece by 2-3cm (i.e., increase the left and right sides of the back piece by 1-1.5cm respectively) on the maximum width of the regular size, and increase the side seams of the back piece by 1-2cm (i.e., increase the left and right side seams by 0.5-1cm respectively); when making the front piece, Figure 1 As shown, the side seam width of the front piece is reduced by 2-3cm compared with the minimum side seam width of the regular size (that is, the left and right sides of the side seam are increased by 1-1.5 sizes respectively); among which, the increase in the side seam of the back piece is always equal to the decrease in the side seam of the front piece; when making the sleeves, if Figure 3 As shown, the sleeve width is increased by 1-1.5cm from the maximum sleeve width of the regular size. By adjusting the size of the back piece and the front piece during the pattern making process, that is, on the basis of the regular size, the width of the back piece is increased by 2-3cm, and the width of the side seam of the front piece is reduced by 2-3cm, so that the back piece of the shirt can better adapt to the back curve of the human body and improve the comfort when wearing. This design effectively solves the problem of poor fit of the back of existing shirts and the easy feeling of restraint, thereby improving the wearing experience.

[0021] Step S2 specifically includes placing the cut pieces in step S1 into a color fixing agent and a softener for color fixing and softening treatment, soaking for 10-15 minutes, then taking them out and placing them in neutral water with a pH value of 7 for cleaning. The cleaning process uses continuous rinsing, and after rinsing, they are placed in an oven and dried at 180°C for 10 minutes. The color fixing agent uses an alcohol-free color fixing agent, and the ratio is: 40-45g / L diethylenetriamine, 20-23g / L ammonium chloride, 18-25g / L dicyandiamide, 22-25g / L propylene glycol, 4-5g / L epichlorohydrin, 5-7g / L acetic acid, and the balance is water. After the alcohol-free color fixing agent is used for color fixing, the decolorization degree of the fabric is less than 0.1%. The decolorization degree values ​​of alcohol-free color fixing agents with different ratios are specifically referenced. Figure 4 As shown in the diagram, the color fixing agent with glycerol can soften the fabric while fixing the color. Glycerol, i.e., glycerin, has strong water absorption and lubricity. Adding it to the color fixing agent can soften the fabric while ensuring color fixing. The softener adopts fatty acid ester type or silicone resin type. The softener of the present application softens the fabric to between 25-30N. Since the practical color fixing agent has a certain softening effect, the concentration of the softener used can be reduced to reduce pollution. In the fabric processing process, a series of process steps such as color fixing, softening, washing, and drying are adopted, especially color fixing and softening treatment. Glycerol is included in the color fixing agent, which can effectively improve the color and feel of the fabric while fixing the color, thereby improving the overall quality of the shirt. The continuous rinsing method adopted in the washing process ensures the cleanliness of the fabric, while the drying and ironing shaping process ensures the dimensional stability and aesthetic appearance of the shirt.

[0022] In step S3, a blind stitch machine is used to sew during the sewing process, and the front piece is tightened and the rear piece is loosened to perform a 0.5-0.8 cm edge trimming according to the tightening and loosening of the front piece and the rear piece in step S1. The blind stitching process is used in the sewing process, which effectively improves the durability of the shirt and avoids the problem of thread derailment caused by exposed stitches. At the same time, the blind stitching process can also keep the appearance of the shirt neat and beautiful.

[0023] Step S4 is specifically as follows: the fabric sewn in step S3 is cleaned with a weak alkaline solution at 40°C and a pH value of 8-9, and then placed in a drying box for drying at 140°C for 10 minutes, and then ironed with a 200°C electric iron for shaping.

[0024] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
