Description

Technical Field

[0001] The invention belongs to the technical field of clothing making, and particularly relates to a production process for preventing blistering of wrinkle-free shirts. Background Art

[0002] As an important part of modern clothing, wrinkle-free shirts have extremely complex production processes and high quality requirements. During the production process, especially when adding lining fabrics to key areas such as collars, sleeve heads, cuffs, and plackets, and when adding welts to side seams, armholes, and bottom edges, there is a severe challenge of blistering. The causes of blistering are varied, including but not limited to uneven distribution of lining adhesive, mismatch between pressing parameters and ironing parameters, incomplete melting of lining adhesive, direct contact after pressing or ironing, offset sewing of welts, missed ironing or pressing, excessive steam spraying during ironing, direct collection of materials without cooling after pressing, and multiple pressing parameters set too high. All of these problems may cause bubbles in the lining or welt areas of wrinkle-free shirts after wearing or washing, seriously affecting the overall quality of the product and the consumer's wearing experience.

[0003] Numerous research efforts have been conducted within the industry to address the blistering problem. For example, patent CN111041854A proposes a fusible interlining for clothing and its production method, aiming to address issues such as poor air permeability, easy transfer of hot melt adhesive to the non-silicone-free direction, and weak adhesion to the fabric, leading to blistering and deformation. By utilizing a non-woven base fabric layer, a coating, a scouring fluid, and multiple adhesive thermoplastic resin composition dots to form the interlining, the interlining effectively improves its air permeability and softness, reduces wrinkles, and avoids adhesive bleed-through. However, while this interlining offers certain advantages in improving adhesion and reducing blistering, it does not directly address the root cause of the blistering problem during the production of wrinkle-free shirts.

[0004] Patent CN112471648A, on the other hand, discloses a method for creating a three-dimensional lapel for a suit. Through meticulous pre-treatment, stitching, fixing, and ironing, the collar ensures a close fit between the collar and the chest lining, shoulder pads, and shoulder seams, resulting in a smooth, blister-free collar and a naturally raised shape that conforms to the concave shape of the human neck and clavicle. This method has achieved significant results in improving the aesthetics and comfort of three-dimensional lapels for suits, but it also fails to directly address the widespread problem of blistering in non-ironing shirts.

[0005] In summary, despite some progress in the industry, the blistering problem of wrinkle-free shirts remains a technical challenge that needs to be addressed. Therefore, a more comprehensive and effective solution is needed to eliminate the blistering problem at the source, thereby improving the overall quality of wrinkle-free shirts and consumer satisfaction. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the above-mentioned defects of the prior art and provide a production process for preventing blistering of iron-free shirts. The produced shirts have good flatness, are washable, and are simple and easy to operate.

[0007] The production process for preventing blistering of iron-free shirts of the present invention comprises the following steps: selecting lining cloth → bonding lining cloth → sewing shirt → ironing → flat pressing → ironing.

[0008] The lining cloth is a high temperature resistant double-sided adhesive lining cloth, which does not tear under the following conditions: temperature 160-175°C, pressure 3.0-4.0 Bar, and speed 4.5-5.5 m / min.

[0009] The specific steps of the adhesive interlining are:

[0010] ①Point interlining: Use a point interlining stick to pre-bond the interlining cloth to the fabric;

[0011] ② Roller pressing: Press the interlining cloth and fabric after lining;

[0012] ③ Cooling: Use the cooling air blowing device to automatically cool the collar, sleeves, cuffs and placket to room temperature after the lining is pressed flat;

[0013] ④Automatic material collection: Use the automatic material collection device to collect materials.

[0014] The point lining parameters are: temperature 135-140℃, time 2-3s.

[0015] The parameters of the flat pressing are: temperature 150-160° C., speed 4-5 m / min, and pressure 3.5-4.5 Bar.

[0016] The specific steps of sewing the shirt are:

[0017] ① Sewing the collar, sleeves, cuffs, placket and lining parts;

[0018] ② Sewing the armholes, side seams, and bottom edges with welts;

[0019] ③ Use the welt in front of the presser foot to automatically pull the welt into the armhole, side seam and bottom edge;

[0020] ④ Use the automatic cutting strip structure to automatically cut the strip.

[0021] The collar and sleeve parts after ironing and sewing are exposed, and the ironing parameters are temperature of 135-140° C. and time of 2-3 seconds.

[0022] The finished placket is flat-pressed, and the armholes, shoulder strips, side seams and bottom edges with flat-pressing parameters are: temperature 160-170° C., speed 5.0-5.5 m / min, pressure 3.5-4.5 Bar, and the garment pieces are cooled after flat-pressing.

[0023] The ironing temperature is 150-160°C.

[0024] Specifically, the production process for preventing blistering of the non-ironing shirt comprises the following steps:

[0025] (1) Select interlining:

[0026] ①Select lining cloth with uniform rubber particles;

[0027] ② Carry out two peeling strength tests on the roller machine. First, cut a few small holes in the lining cloth evenly, then peel the lining cloth horizontally from the fabric until the lining cloth is completely peeled off from the fabric, and observe whether the lining cloth rubber particles on the fabric are evenly distributed.

[0028] ③ Determine the best matching lining fabric and test parameters. The test parameters are temperature 160-175℃, pressure 3.0-4.0Bar, and speed 4.5-5.5m / min.

[0029] (2) Fusible interlining:

[0030] ① Point interlining: Use a point interlining stick to pre-bond the interlining to the fabric. Control the iron temperature to lightly stick the interlining to the fabric. The parameters are: temperature 135-140℃, time: 2-3s;

[0031] ② Roller flat pressing: temperature 150-160℃, speed 4-5m / min, pressure 3.5-4.5Bar;

[0032] ③ Cooling: Use the cooling and blowing device of the roller machine to automatically cool the collar, sleeve head, sleeve flap, and placket parts after flat pressing to room temperature. Do not touch the lining parts after flat pressing and before cooling, otherwise it will easily cause bubbles;

[0033] ④ Automatic material collection: Using the automatic material collection device of the roller machine, the cooled collar, sleeve head, sleeve flap and placket parts automatically enter the material collection trough.

[0034] (3) Sewing shirts:

[0035] ① Sewing the collar, sleeves, cuffs, placket and lining parts;

[0036] ② Sewing the armholes, side seams, and bottom edges with welts;

[0037] ③Equipment-based welting: Utilize the automatic welting fixture in front of the presser foot of the sewing equipment to automatically pull welts into the armhole, side seams, bottom hem, and other locations to prevent welt deviation, welt leakage, and blistering after flat pressing.

[0038] ④ Automatically cut off the fillet: Use the automatic cutting fillet in front of the sewing equipment.

[0039] (4) Ironing:

[0040] ①Iron the collar and cuffs after sewing, and sew the visible seams. Ironing parameters: ironing temperature is 135-140℃, and the ironing time is 2-3s;

[0041] (5) Pressing: Press the sewn placket, the armhole, shoulder, side seam and bottom edge with welts. Pressing parameters: temperature 160-170℃, speed 5.0-5.5m / min, pressure 3.5-4.5Bar. Cool the garment pieces after pressing. Do not touch the parts before cooling after pressing, otherwise it will easily cause blistering.

[0042] (6) Ironing: The iron temperature should be 150-160℃. Please use less steam during this process. Just touch the iron lightly to iron the shirt.

[0043] The production process of the present invention includes six steps: interlining testing, bonding interlining, sewing, ironing, flat pressing, and ironing the finished product. The interlining test involves selecting an interlining with uniform rubber particles that matches the fabric, performing two peel strength tests on a roller machine, first cutting several small holes in the interlining, then peeling the interlining horizontally from the fabric until the interlining is completely peeled off from the fabric, observing the distribution of interlining rubber particles on the fabric, whether the rubber particles are uniform, and determining the best matching interlining and test parameters. The bonding interlining includes point interlining, roller flat pressing, automatic material collection, and cooling. The sewing process includes sewing the collar, sleeve head, sleeve flap, placket, and other parts with interlining, as well as the armhole, shoulder, side seam, and bottom hem with inlays, adding inlays and automatically cutting the inlays. The ironing process includes ironing the collar, sleeve head, and other parts. Flat pressing includes flat pressing the placket and the inlays, followed by cooling. The ironing process includes ironing the entirety of the non-ironing shirt, using minimal steam and ironing lightly. The invention can prevent the wrinkle-free shirt from bubbling through the processes of lining cloth testing, lining cloth bonding, sewing, ironing, flat pressing and finished product ironing.
