Bonded thread is a high-quality sewing thread made of bonded nylon and polyester filaments. It uses a special process to bond multiple strands of silk together to form a whole, so as to achieve the purpose of not loosening and not linting during the sewing process.
Classification of bonded thread according to material and bonding process
Bonded Nylon Thread: It is made of nylon (nylon) filament plying and twisting thread, bonded by internal process, with high tensile strength and wear resistance, suitable for sewing durable products.
Bonded Polyester Thread: It is made of polyester filament plying and twisting thread, made by external or internal bonding process, with high temperature resistance, no stretching, no fading and other characteristics, suitable for sewing high-quality sewing products.
Bondy thread has the following characteristics
- High tensile strength: Bonded thread enhances the tensile strength of the thread through the bonding process, making it not easy to break during sewing. Due to the use of high-quality nylon and polyester filaments, bonded sewing thread has high tensile strength.
- Good wear resistance: Due to the strength of nylon or polyester, the bonded thread can maintain good wear resistance during use and is suitable for long-term use.
- Small shrinkage: Compared with ordinary sewing threads, the bonded thread has a lower shrinkage rate and is not easy to shrink during the sewing process, which helps to maintain the stability of the shape and size of the sewn finished product.
- Moderate elasticity: The bonded thread has good elasticity, which makes the seams smooth and is suitable for sewing materials with high elasticity requirements.
- Smooth seams: The characteristics of the bonded thread enable it to produce smooth seams during the sewing process, which is suitable for high-quality sewing products.
- Waterproof and mildew-proof: Some bonded thread products have waterproof and mildew-proof properties, which are suitable for sewing needs in special environments.
- No stretching: It will not stretch during the sewing process to ensure the quality of sewing.
- No fading: It has good color fastness and is not easy to fade.
- No break: It is not easy to break during high-speed sewing.
- No linting: The surface is smooth and not easy to burr.
Conclusion
Bondy thread shows excellent performance in the sewing process, such as high tensile strength, good wear resistance, small shrinkage, moderate elasticity and smooth seams.
Bondy thread is widely used in various high-quality sewing products, such as car seats and airbags, leather furniture, bags, parachutes, diving suits, high-end sports shoes, tents, sails, car awnings and high-end mattresses.
