Description

Technical Field

[0001] The invention belongs to the technical field of clothing making, and in particular relates to a production process for preventing blistering of iron-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 linings to key parts such as collars, sleeves, sleeve flaps, plackets, and when adding welts to side seams, armholes, bottom edges, etc., there are severe challenges in the form of blistering. The causes of blistering are varied, including but not limited to uneven distribution of lining adhesive, mismatch between flat pressing parameters and ironing parameters, incomplete melting of lining adhesive, direct contact after flat pressing or ironing, offset of welts from garment pieces, missed ironing or missed pressing, excessive steam spraying during ironing, direct collection of materials without cooling after flat pressing, and multiple flat pressing parameters set too high. All of these problems may cause blistering in the lining or welts of wrinkle-free shirts after wearing or washing, seriously affecting the overall quality of the product and the wearing experience of consumers.

[0003] Many explorations have been conducted in the industry to address the blistering problem. For example, patent CN111041854A proposes a garment adhesive lining and its production method, which aims to solve the problems of poor air permeability of the lining, easy transfer of hot melt adhesive to the non-silicone direction, and weak adhesion to the fabric leading to blistering and deformation. By using a non-woven base fabric layer, a coating, a scouring liquid, and a plurality of adhesive thermoplastic resin composition points to form the lining, the air permeability and softness of the lining are effectively improved, wrinkles are reduced, and the occurrence of glue seepage is avoided. However, although this lining has certain advantages in improving the bonding effect and reducing blistering, it does not directly address the root cause of the blistering problem in the production process of iron-free shirts.

[0004] On the other hand, patent CN112471648A discloses a method for making a three-dimensional lapel of a suit. Through the steps of fine pretreatment, stitching, fixing and ironing, the collar is ensured to be closely fitted with the chest lining, shoulder pads, shoulder seams and other parts, so that the collar is flat and free of bubbles, and naturally warped, which meets the needs of the concave shape of the human neck and clavicle. This method has achieved remarkable results in improving the aesthetics and comfort of the three-dimensional lapel of a suit, but it also does not directly study and solve the universality of the bubble problem of iron-free shirts.

[0005] In summary, although some progress has been made in the industry, the blistering problem of non-ironing shirts is still a technical problem that needs to be solved urgently. Therefore, a more comprehensive and effective solution is needed to eliminate the blistering problem from the source and improve the overall quality of non-ironing 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 shirts→ironing→flat pressing→ironing.

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

[0009] The specific steps of the bonding interlining are: ① Point interlining: Use a point interlining stick to pre-bond the interlining cloth to the fabric; ②Roller machine flat pressing: flat press the interlining cloth and the fabric after point lining; ③ Cooling: Use the cooling blowing device to automatically cool the collar, sleeves, sleeves and placket to room temperature after the lining is pressed flat; ④Automatic material collection: Use automatic material collection device to collect materials.

[0010] The point lining parameters in the point lining are: temperature 135-140℃, time 2-3s.

[0011] The parameters of the flat pressing are: temperature 150-160°C, speed 4-5m / min, pressure 3.5-4.5Bar.

[0012] The specific steps of sewing the shirt are: ① Sewing collars, sleeves, cuffs, plackets and lining parts; ② Sewing the armholes, side seams, and bottom edges with welts; ③ Use the welt in front of the presser foot to automatically pull the welt into the armhole, side seam and bottom edge; ④ Use the automatic cutting strip structure to automatically cut off the strip.

[0013] The collar and sleeve parts after ironing are sewn, and the visible seams are sewn. The ironing parameters are temperature of 135-140° C. and time of 2-3 seconds.

[0014] The flat pressing sewn placket, the armhole, shoulder, side seam and bottom edge with welt are flat pressed. The flat pressing parameters are as follows: temperature 160-170°C, speed 5.0-5.5m / min, pressure 3.5-4.5Bar, and the flat pressed garment pieces are cooled.

[0015] The ironing temperature is 150-160°C.

[0016] Specifically, the production process for preventing blistering of the non-ironing shirt comprises the following steps: (1) Select lining fabric: ①Select lining cloth with uniform rubber particles; 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 uniform; ③ Determine the best matching lining fabric and test parameters. The test parameters are temperature 160-175℃, pressure 3.0-4.0Bar, speed 4.5-5.5m / min.

[0017] (2) Fusible interlining: ① Point interlining: Use a point interlining rod to pre-bond the interlining cloth to the fabric. The temperature of the iron is controlled to lightly stick the interlining cloth to the fabric. The parameters are: temperature 135-140℃, time: 2-3s; ② Roller flat pressing: temperature 150-160℃, speed 4-5m / min, pressure 3.5-4.5Bar; 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; 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.

[0018] (3) Sewing shirts: ① Sewing collars, sleeves, cuffs, plackets and lining parts; ② Sewing the armholes, side seams, and bottom edges with welts; ③ Equipment adding welts: Use the automatic welt fixing device in front of the presser foot of the sewing equipment to automatically pull the welts into the armhole, side seam and bottom edge to prevent the welts from shifting, causing welt leakage after flat pressing and causing blistering; ④ Automatically cut off the welt: Use the automatic cutting of the welt in front of the sewing equipment.

[0019] (4) Ironing: ①Iron the collar and sleeves after sewing, and sew the visible seams. Ironing parameters: ironing temperature is 135-140℃, and the time is 2-3s; (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, and cool the garment pieces after pressing. Do not touch the parts after pressing but before cooling, otherwise it will easily cause blistering.

[0020] (6) Ironing: The iron temperature should be between 150-160℃. Please use less steam during this process. Just touch the iron lightly to iron the shirt.

[0021] The production process of the present invention includes six processes: lining cloth test, bonding lining cloth, sewing, ironing, flat pressing, and finished product ironing. The lining cloth test includes selecting lining cloth with uniform rubber particles that match the fabric, performing two peeling strength tests on the roller machine, first cutting a few small holes in the lining cloth evenly, then peeling the lining cloth horizontally from the fabric, until the lining cloth is completely peeled off from the fabric, observing the distribution of rubber particles of the lining cloth on the fabric, whether the rubber particles are uniform, and determining the best matching lining cloth and test parameters. The bonding lining cloth includes point lining, roller flat pressing, automatic material collection, and cooling; the sewing process includes sewing the collar, sleeve head, sleeve flap, placket and other parts with lining cloth, as well as the armhole, shoulder, side seam, and bottom edge with welts, the equipment adds welts and automatically cuts off the welts, the ironing process includes ironing the collar, sleeve head and other parts; flat pressing includes flat pressing the placket and the part with welts, and then cooling; the ironing process includes ironing the non-ironing shirt as a whole, and this process sprays less steam and irons gently. 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.
