High strength sewing threads are specialized threads designed for specific uses where high tensile strength and durability are necessary. This type of thread is commonly used for sewing protective workwear, outdoor gear, leather goods, upholstery, and other heavy-duty applications. In this article, we will discuss what high strength sewing thread is, its composition, and its applications.
High strength sewing threads are heavily used in commercial and industrial sewing, where robust, durable, and long-lasting stitches are absolutely necessary. The thread’s breaking strength and resistance to abrasion, stress, and chemicals are key factors in determining its quality and suitability for specific applications.
What Is High Strength Sewing Thread?
High strength sewing thread is a specialized type of thread designed to provide exceptional strength, durability, and seam integrity. This type of thread is usually made from a blend of materials designed specifically for their strength and performance properties. The composition of high strength thread usually consists of materials such as:
- Aramid: Aramid threads are known for their unmatched strength and heat-resistant properties. Kevlar is one of the most common aramid materials used in sewing threads.
- Nylon: Nylon threads provide excellent flexibility and durability. Nylon threads are also resistant to abrasion, making them ideal for use in items that undergo heavy wear and tear.
- Polyester: Polyester threads are made from polyester fibers that are twisted and spun together. Polyester threads are known for their excellent resistance to UV light, chemicals, and moisture.
- Polypropylene: Polypropylene threads are lightweight, highly resistant to water, and known for their excellent resistance to acids, alkalies, and oils.
Composition of High Strength Sewing Thread
High strength sewing thread is composed of different raw materials in varying ratios, depending on the application and specific performance requirements. Thread manufacturers often use different combinations of materials and production methods to create threads that are well-suited to different applications. Here is a breakdown of the various materials that can be used in high strength sewing thread and their properties:
- Kevlar: Kevlar is a synthetic fiber that is five times stronger than steel. It is used in high strength sewing threads because of its remarkable strength and resistance to abrasion and heat.
- Polyester: Polyester is a synthetic fiber that is known for its dimensional stability, resistance to mildew, and resistance to UV light. It is often blended with stronger fibers to improve durability and enable the production of high strength sewing threads.
- Nylon: Nylon is a synthetic fiber that is widely used in high strength sewing threads because of its high strength, durability, and resistance to abrasion.
- Cotton: Cotton fibers can be combined with synthetic fibers to create high strength sewing threads. Cotton provides good durability, but it is not as strong as some other fibers.
Applications of High Strength Sewing Thread
High strength sewing threads are a crucial component in manufacturing heavy-duty applications such as:
- Protective Workwear: Protective workwear such as fire-resistant garments, bulletproof vests, and welding clothing, require high strength sewing threads to ensure seam integrity and maximum protection.
- Outdoor Gear: Outdoor gear, such as tents, backpacks, and sleeping bags, undergo extreme weather conditions and heavy wear and tear. High strength sewing threads are ideal for these applications, as they are resistant to UV light, moisture, and abrasion.
- Leather Goods: Leather goods, such as boots, belts, and wallets, require high strength sewing threads to withstand the stress and strain of daily use.
- Upholstery: Upholstery sewing requires high strength threads to ensure that the seams hold up to daily use.
High strength sewing threads are essential for heavy-duty sewing applications and are made from different materials such as aramids, nylon, polyester, and polypropylene. The combination of different materials provides the necessary strength, durability, and seam integrity needed for high performance. The right selection of high strength sewing thread depends on the specific application. In any case, an appropriate thread choice will ensure that the final product will meet the performance requirements.
