Bonded Nylon Sewing Thread Wholesale from China's Factory Directly

Bonded Nylon Thread,made of Nylon 66, is commonly used for stitching upholstery, leather, vinyl, and other durable fabrics. It offers superior strength and heat resistance compared to standard nylon threads, providing high tensile strength ideal for tasks demanding robust and flexible materials. The thread is treated with a bonding agent that enhances its strength and minimizes friction at the needle point, resulting in seamless and smooth stitching. This bonding also prevents snagging, ensuring smooth stitches throughout the task.

Bonded Nylon Thread Main Features

Excellent tenacity
Excellent UV and abrasion protection
Low elongation
High waterproof property
Ideal for leather products, footwear, upholstery, and technical textiles.

Bonded Nylon Thread Material

The bonded nylon thread is made of Nylon 6.6 or 6 synthetic fibers. Nylon 6 and Nylon 66 are both commonly used synthetic polymers known as polyamides. The numbers represent the amount and variant of the carbon atoms in the chemical structure from which they are formed.

For example:

Nylon 6 is created from caprolactam, which consists of 6 carbon atoms, while nylon 66 is produced from adipic acid, which has 6, and hexamethylene diamine, which also has 6.
Most nylons, including 6 and 66, are semi-crystalline and possess good strength and durability, making them an ideal choice for demanding projects.

Bonded Nylon Thread Applications

Designed for heavy-duty sewing applications. Bonded Nylon is the popular choice to use when stitching upholstery, leather, vinyl, and other heavy fabric. MH's Bonded Nylon is Nylon 6,6 (sometimes referred to as Nylon 66) which is stronger and has a higher heat tolerance than regular Nylon threads.
