Nylon 66 Inner Bonded Yarn
Introduction
Bonded thread, also known as bonded nylon thread, is a type of thread that is commonly used in sewing and stitching applications. It is made by bonding or coating nylon fibers together with a special adhesive or resin.
The bonding process involves applying heat and pressure to the nylon fibers, which melts the outer layer and fuses the strands together. This creates a thread that is stronger, more durable, and less prone to fraying or unravelling.
Structure
Inner bonded and outer bonded thread are terms used to describe different types of bonded threads based on their construction and application.
Inner Bonded Thread: Inner bonded thread, also known as core bonded thread, has a bonded or coated nylon core with an outer wrapping of polyester or another material. The core provides strength and stability, while the outer wrapping provides additional protection and improves the thread’s appearance. Inner bonded thread is commonly used in applications where high tensile strength and resistance to abrasion are required, such as heavy-duty sewing, upholstery, and leatherwork.
Outer Bonded Thread: Outer bonded thread, also known as sheath bonded thread, has a bonded or coated nylon sheath covering a core of polyester or another material. The sheath provides additional strength, abrasion resistance, and protection against fraying or unraveling. Outer bonded thread is often used in applications that require a more visible or decorative stitching, such as footwear, sports equipment, and outdoor gear.
- Both inner bonded and outer bonded threads offer enhanced durability, resistance to abrasion, and superior strength compared to regular sewing threads. The specific choice between inner bonded and outer bonded thread depends on the specific requirements of the sewing project, including the desired appearance, strength, and performance characteristics.
Applications
Bonded thread is known for its high tensile strength and resistance to abrasion, chemicals, and UV radiation. It is commonly used in applications that require strong and durable stitching, such as leather goods, upholstery, footwear, outdoor gear, and heavy-duty fabrics. It is also used in industrial sewing applications, including automotive upholstery, luggage manufacturing, and sailmaking. The bonded nature of the thread allows it to maintain its integrity even when exposed to harsh conditions or repetitive stress.
