What is Bar Tacking?
Bar tacking is a sewing technique used to reinforce specific areas of a garment, such as pockets, belt loops, and buttonholes. It involves sewing a series of close zigzag stitches that form a bar-shaped reinforcement. This technique is crucial in areas that experience high stress and wear, ensuring the durability of the garment.
Importance of Bar Tacking
Bar tacking serves multiple purposes in garment construction:
- Strength and Durability: The reinforcement provided by bar tacks helps prevent holes, tears, and seam breakage, especially in high-stress areas.
- Customized Reinforcement: Depending on the application, bar tacks can be adjusted in size and pattern to meet specific needs.
- Aesthetic Appeal: In some instances, bar tacks can be sewn in contrasting colors to add a decorative element to the garment.
Types of Bar Tack Sewing Machines
Bar tack sewing machines come in various types, each with distinct features and applications. Below are some common types:
1. Industrial Bartack Machines
These machines are designed for high-volume production and can handle a large number of stitches per minute. They often come with multiple preset stitch patterns, making them versatile for different applications.
2. Home Sewing Machines
Many home sewing machines now come equipped with bar tack capabilities. While they may not be as fast as industrial machines, they are perfect for DIY enthusiasts looking to reinforce their sewing projects.
3. Computer-Controlled Bartack Machines
These sophisticated machines allow users to program custom stitch patterns. They are ideal for businesses that require unique reinforcement patterns for their products.
4. Full Automatic Bartack Machines
These machines are designed for mass production, capable of sewing numerous bar tacks efficiently without manual intervention.
Working Principle of Bar Tack Machines
Bar tack sewing machines operate on a simple yet effective principle. They create a series of zigzag stitches tightly packed together to form a strong reinforcement. The process typically involves:
- Sewing Long Stitches: The machine sews long, narrowly spaced stitches along the desired line.
- Adding Short Stitches: Short stitches are then added perpendicularly to the long stitches, which helps in securing the bar.
- Repetition: The sewing cycle repeats until the desired reinforcement is achieved.
Applications of Bar Tack Sewing Machines
Bar tacks are used in various applications, including:
- Garment Manufacturing: Reinforcing pockets, belt loops, and buttonholes in clothing.
- Outdoor Gear: Used in backpacks and tents where webbing attaches to fabric.
- Automotive and Upholstery: Strengthening seams in car upholstery and furniture.
