The Stitching and garment construction have a significant impact on the final appearance of a garment. Achieving an accurate fit relies heavily on the quality of stitching and construction. These details play a significant role in the tech pack, as they determine the fit and durability of the garment. It is crucial for the stitching and construction instructions to be clear and precise. The expertise of the tech pack designer is crucial in conveying this information effectively. The factory follows these instructions to process the batch, and the order of sewing machines and operators can greatly impact production capacity and output quality. Having a well-planned and detailed approach can make a significant difference in the overall outcome.

Below are the three common way of stitching methods. In addition to that, manufacturers use various other sophisticated machines in the garment manufacturing process. So, a tech pack designer must know the methods of stitching to plan the stitching and construction details. The job of a tech pack designer is to mention the right stitching and garment construction details to plan the style. Only designers having grassroots-level experience in a factory environment can explain them in a tech pack.

Important Components in Stitching and Garment Construction Detailing

1. Seams: Seams are the most common type of stitching used to join fabric panels together. There are various types of seams, including plain seams, French seams, flat-felled seams, and overlock seams. The choice of seam depends on the fabric type, garment style, and desired aesthetic.

2. Hems: Designers use hems to finish the edges of a garment. Common types of hems include single-fold hems, double-fold hems, blind hems, and rolled hems. The choice of hem depends on the fabric weight, garment style, and desired finish.

3. Darts: Darts are stitching details used to shape fabric and create a fitted silhouette. Garments such as dresses, skirts, and pants commonly use darts. Designers can choose between tapered or straight darts, and the placement and size of these darts are crucial for achieving the desired fit.

4. Pleats: Designers use pleats to create volume or shape in garments by stitching folds of fabric. Pleats find common usage in skirts, dresses, and sleeves. The depth and direction of pleats are important considerations for achieving the desired aesthetic and functionality.

5. Collars and Cuffs: Collars and cuffs require specific stitching techniques to ensure proper shaping and durability. Designers commonly use topstitching to secure collars and cuffs while also adding decorative detailing to garments.

6. Zippers and Fastenings: Zippers and other fastenings require precise stitching techniques to ensure proper functionality and secure attachment. Designers often utilize topstitching and reinforcement stitching to strengthen these areas in garments.

7. Pockets: Designers have the flexibility to use various techniques, such as patch pockets, welt pockets, or inseam pockets, to stitch pockets onto garments. The stitching should be secure and aligned properly to maintain the integrity and functionality of the pockets.

These are just a few examples of stitching and garment construction details that are important to consider in a tech pack. The specific stitching techniques and construction methods may vary depending on the garment style and design. Providing clear and detailed instructions for each stitching detail is crucial for achieving the desired outcome.

Overlock Stitch ( Sergers Stitch ) Famously Knows as Cover Stitching

Overlock stitching, also known as serging, is a crucial stitching process used in garment construction. It is a common practice to use it for edging and seaming fabric pieces together, as it provides a clean finish and prevents fraying. Here are some key points about overlock stitching:

1. Purpose: The primary purpose of overlock stitching is to protect the fabric edges from unraveling or fraying. By enclosing the raw edges with multiple threads, overlock stitching enhances the durability and longevity of the garment.

2. Fabric Compatibility: Overlock stitching is suitable for both woven and knitted fabrics. It is particularly important for knit fabrics that have a tendency to unravel due to their structure.

3. Machine Varieties: Overlock sewing machines come in various configurations, offering different numbers of threads. The most common types are 3-thread and 4-thread overlock machines. Some advanced machines also provide a 5-thread option. The choice of machine and thread configuration depends on the desired finish and fabric type.

4. Stitch Formation: Overlock stitching typically creates a stitch that wraps around the fabric edge, securing it with multiple threads. The stitching process involves trimming excess fabric, enclosing the edge with threads, and simultaneously stitching and serging the fabric layers together.

5. Seam Finishes: Designers can use overlock stitching to finish seam edges, creating a neat and professional appearance on both the inside and outside of the garment. This technique proves particularly useful when the seams are visible or when a clean finish is desired.

6. Stretch and Flexibility: Overlock stitching provides a degree of stretch and flexibility to the garment seams, making it suitable for garments that require ease of movement or have stretchy fabric compositions.

Overall, overlock stitching is an essential technique in garment construction to ensure the durability, longevity, and professional finish of the finished product. Including clear instructions for overlock stitching in the tech pack is important to achieve the desired result during the manufacturing process.

Single Needle Stitching ( Lock Stitch In Singer )

Garment manufacturers widely use single-needle machines, particularly for stitching woven garments, in the process of garment manufacturing. Here are some key points about single-needle stitching:

1. Machine Type: Single-needle machines, also known as lockstitch machines, are the most commonly used sewing machines in the apparel industry. They use a single needle to create a lockstitch, which consists of an upper thread and a bobbin thread interlocking within the fabric layers.

2. Suitable for Woven Fabrics: Single-needle stitching is particularly suitable for woven fabrics such as shirts, trousers, dresses, and denim. These fabrics are usually less stretchy and have a more rigid structure, making them compatible with the straight stitch produced by single-needle machines.

3. Stitch Formation: Single-needle machines create a strong and secure stitch by passing the needle through the fabric layers and interlocking the upper thread with the bobbin thread. This lockstitch is known for its durability and resistance to unraveling.

4. Versatility: Single-needle machines offer versatility in stitch length, tension, and other settings, allowing operators to adjust the stitching according to the fabric type and desired outcome. This versatility enables garment manufacturers to produce a wide range of styles and designs.

5. Precision and Control: Single-needle machines provide precise control over the stitching process, allowing operators to achieve accurate seam lines, topstitching, and other decorative details. This makes them suitable for creating clean and professional finishes on garments.

6. Commonly Seen on Labels: Dress shirt labels or garment tags often mention the term “single needle stitching” to indicate the use of lockstitch machines. This assures customers that the garment has been constructed using a reliable and durable stitching method.

Single-needle stitching is an essential technique in garment manufacturing, especially for woven garments. It is important to provide clear instructions for single-needle stitching in the tech pack, specifying the stitch length, seam allowances, and any other relevant details to ensure consistency and quality during production.

Flatlock Stitching

Flatlock stitching is commonly used in jersey and stretchable fabrics. Here are some key points about flatlock stitching:

1. Suitable for Stretchable Fabrics: Flatlock stitching is ideal for sewing knitwear and stretchable fabrics, including jerseys, activewear, swimwear, and other garments that require stretch and flexibility. It allows the seams to expand and contract with the fabric without breaking or causing discomfort.

2. Strong and Flexible Seam: The flatlock stitch creates a strong and flexible seam that can withstand the stretching and movement of the fabric. Designers purposefully design it to provide both durability and comfort, making it suitable for sportswear and other active apparel.

3. Appearance: Flatlock stitching creates a seam that is flat and has the same appearance on both sides of the fabric. This is achieved by overlapping the fabric layers and stitching them together with multiple threads. The resulting stitch often resembles a ladder-like pattern on the outside of the garment.

4. Stretchability: One of the key advantages of flatlock stitching is its ability to maintain the stretchability of the fabric. Unlike other stitches that may restrict the fabric’s stretch, flatlock stitching allows the garment to retain its elasticity and conform to the body’s movements.

5. Decorative and Functional: Not only does flatlock stitching serve a functional purpose, but it also allows designers to use it as a decorative element in garment design. Designers can achieve this by employing matching or contrasting threads, which enhance the visual appeal of the seams and create a distinct aesthetic.

6. Use of Specialized Machines: Flatlock stitching requires specialized machines. We generally refer to those machines as flatlock machines, which are equipped with multiple needles and loopers. These machines are specifically designed to efficiently and accurately create the flatlock stitch.

When including flatlock stitching in the tech pack, it is important to provide clear instructions on the stitch formation, thread color, and any specific details regarding the placement and width of the flatlock seams. This ensures that the desired look and functionality are achieved during the garment production process.
