The process of sewing jackets and its common mistakes

The process of sewing jackets and its common mistakes
Sewing jackets is a complex and delicate work involving multiple links and processes. Understanding the common mistakes in these processes is crucial to improving the quality and production efficiency of jackets. This article will discuss in detail the various process links of sewing jackets and the errors that are easy to occur, and provide corresponding solutions to help you avoid these problems.

Errors in fabric selection and pretreatment links
Error 1: Improper fabric selection
The properties of different fabrics vary greatly, such as elasticity, breathability, wear resistance, etc. If the selected fabric is not suitable for the style and purpose of the jacket, it will affect the quality and wearing experience of the final product. For example, for outdoor sports jackets, if fabrics with poor breathability and wear resistance are selected, it will not meet the needs of consumers.
Solution: Before fabric selection, you must fully understand the purpose of the jacket, the target customer group, and the wearing scene. Based on these factors, consider the various characteristics of the fabric and choose the right fabric. At the same time, you can refer to industry standards and successful cases, consult fabric suppliers, and get professional advice.
Error 2: Insufficient fabric pretreatment
The fabric of the jacket usually needs to be pretreated before cutting and sewing, such as shrinkage, decontamination, and static removal. If the pretreatment is insufficient, the jacket may shrink unevenly, deform, wrinkle and other problems during subsequent processing and use.
Solution: Strictly follow the pretreatment requirements provided by the fabric supplier and pretreat each batch of fabric accordingly. During the pretreatment process, pay attention to controlling parameters such as water temperature, washing time, and drying temperature to ensure the consistency of the pretreatment effect. At the same time, the performance of the pretreatment equipment should be checked regularly to ensure its normal operation.
Errors in the cutting process
Error 1: Inaccurate cutting size
Cutting is one of the key steps in sewing a jacket. If the cutting size is inaccurate, the various parts of the jacket cannot be properly spliced, affecting the overall appearance and wearing comfort. For example, deviations in the length, width, and sleeve size of the garment piece may cause the jacket to not fit.
Solution: Use high-precision cutting equipment and tools, such as automatic cutting machines, laser cutting machines, etc., to ensure the accuracy of the cutting size. Before cutting, carefully check the cutting drawings and cutting plans to ensure that each part cut meets the design requirements. At the same time, the cutting equipment should be regularly maintained and calibrated to ensure its normal operation.
Error 2: Improper selection of cutting tools
Different fabrics and cutting requirements require different cutting tools. If the selected tool is not suitable, it may cause problems such as uneven cutting edges, excessive burrs, and blade wear, affecting the cutting quality and subsequent sewing process.
Solution: Choose appropriate cutting tools according to the characteristics of the fabric and cutting requirements. For example, for soft fabrics, sharp scissors can be used; for harder fabrics, professional cutting tools can be used. At the same time, pay attention to regular replacement of blades to keep the sharpness of the tool.

Errors in sewing process
Error 1: Improper selection of stitches
The quality and performance of stitches directly affect the sewing quality and durability of the jacket. If the selected stitches are not strong enough, the color does not match the fabric, or the thread diameter is too thick, it will cause problems such as broken thread, skipped thread, uneven stitches, etc. during the sewing process, affecting the appearance and quality of the jacket.
Solution: Choose stitches of appropriate strength, color and thread diameter according to the characteristics of the fabric and the purpose of the jacket. When choosing stitches, factors such as the material, twist, and elongation of the stitches should be considered to ensure that the quality and performance of the stitches meet the requirements. At the same time, the quality of the stitches should be checked regularly to avoid using poor quality stitches.
Error 2: Uneven stitch length When sewing a jacket, the uniformity of the stitch length is crucial to ensure the quality and strength of the sewing. If the stitch length is too long or too short, or the stitch length is uneven, it will cause the seams of the jacket to crack easily, the stitches to be uneven, and other problems, affecting the appearance and durability of the jacket.
Solution: Adjust the stitch length setting of the sewing machine to ensure the consistency of the stitch length. During the sewing process, check the uniformity of the stitch length frequently and adjust it in time if problems are found. At the same time, the sewing machine should be maintained and serviced regularly to ensure its normal operation.

Errors in the coordination of cutting and sewing
Error 1: The order of cutting and sewing is unreasonable In the process of sewing a jacket, the order of cutting and sewing is very important. If the order is unreasonable, the various parts of the jacket cannot be properly spliced, increasing the difficulty and workload of sewing. For example, sewing the lining first and then the garment pieces, or sewing the sleeves first and then the body, etc., may cause deviations in the size and shape of the jacket.
Solution: Develop a reasonable cutting and sewing sequence, generally in the order of cutting first and then sewing, large parts first and then small parts, and inside first and then outside. Before cutting and sewing, carefully study the process flow and drawings to ensure that the order of each step is correct. At the same time, strengthen supervision and management during the production process to ensure that employees operate in the correct order.
Error 2: The precision of cutting and sewing does not match
The precision of cutting and sewing needs to be coordinated with each other. If the precision of cutting is high, but the precision of sewing is not enough, or vice versa, the quality of the jacket will be affected. For example, the size of the cut garment pieces is very accurate, but there are problems such as seam offset and uneven stitch length during sewing, which will cause the size and shape of the jacket to change and fail to achieve the desired effect.
Solution: Improve the precision of cutting and sewing to ensure that the precision of the two matches. During the cutting process, high-precision equipment and tools should be used to cut strictly according to the drawings; during the sewing process, the parameters of the sewing machine should be adjusted to ensure that the stitch length, stitches, etc. of the sewing meet the requirements. At the same time, quality control should be strengthened, and each link of cutting and sewing should be strictly inspected, and problems should be corrected in time.

Errors in the ironing process

Error 1: Inappropriate ironing temperature and time

Ironing is an indispensable part of the jacket sewing process. If the ironing temperature is too high or too low, or the ironing time is too long or too short, it will affect the quality of the jacket. For example, if the temperature is too high, the fabric may discolor, wrinkle, deform, etc.; if the temperature is too low, the ironing effect cannot be achieved, and the wrinkles and shape of the jacket cannot be effectively improved.

Solution: Determine the appropriate ironing temperature and time according to the characteristics of the fabric and the style of the jacket. During the ironing process, closely observe the changes in the fabric to avoid overheating or underheating. At the same time, regularly check the performance of the ironing equipment to ensure that its temperature control is accurate.

Error 2: Incorrect ironing method
Different fabrics and jacket parts require different ironing methods. If the ironing method is not correct, the appearance and quality of the jacket may be affected. For example, for some special fabrics, such as leather, wool, etc., steam ironing or low-temperature ironing may be required; while for the collar, cuffs and other parts of the jacket, special ironing techniques and tools are required to ensure its flatness and shape.
Solution: Learn and master the correct ironing methods for various fabrics and jacket parts, and choose appropriate ironing tools and methods according to actual conditions. During the ironing process, pay attention to controlling the strength and angle to avoid excessive ironing or insufficient ironing.

Errors in quality control links
Error 1: Lack of an effective quality control system
The quality control of sewing jackets involves multiple links, including fabric inspection, cutting quality inspection, sewing quality inspection, finished product inspection, etc. If there is a lack of an effective quality control system, it is impossible to detect and correct errors and problems in the production process in time, resulting in unqualified quality of the final product.
Solution: Establish a complete quality control system and clarify the quality control standards and inspection methods for each link. During the production process, the quality control plan must be strictly implemented, and the products in each link must be strictly inspected and tested to ensure that the product quality meets the requirements. At the same time, it is necessary to strengthen the training and management of quality control personnel to improve their professional quality and work responsibility.
Error 2: Lax quality inspection
Even if there is a quality control system, the quality of the jacket cannot be guaranteed if the quality inspection is not strict.
