100% Bonded Thread with high-quality high strength nylon filament or polyester filament. Divided into two types: foreign and inner, with soft and special strong bonding, and then highly efficient lubrication. In addition to the characteristics of ordinary high strength sewing thread, it also has the advantages of high tensile strength, good wear resistance, small shrinkage rate, moderate elastic stitching, etc. It is widely used for sewing car seat and airbag, leather furniture, luggage, parachute Daily high-quality sewing products such as wetsuits, high-end sneakers, tents, sails, hoods and advanced mattresses. ( 100% Bonded Polyester & Nylon Thread, Bonded Filament Sewing Thread )
The simplest test method: twist the sewing thread strand clockwise by hand, and screw the ordinary sewing thread. If it cannot be opened, it can be judged as Bonded sewing thread.
Bonded threads are sewing threads that are bonded together without strands.
Advantages of Nylon Bonded Thread
During the sewing work, the sewing thread is driven by the sewing needle eye, inserted into the fabric to be sewn, and intersected with the bottom thread to achieve the purpose of stitching. Through the process of needle eye, the most direct force on the sewing thread is extrusion. The most obvious damage to the sewing thread is the squeezing. This is the reason for the extrusion. As the accumulation of shares will form a knot, the final result will be loose stocks and broken lines.
Bonded thread is a sewing thread that does not loosen the strand. Bonded thread is in the process of twisting the thread. A hot fuse is added in the middle of the strand. After the sewing thread is plied, it is heated and shaped, and the strand is bonded from the inside. Live, so Bonded thread is not a sewing thread.
Introducing the concept of single-strand, the single-strand force of the needle eye is the advantage of Bonded thread. If the Bonded thread is not in the eye of the needle, it is internally bonded together, so it does not retreat, wrinkle, and not scatter. The stock, so the probability of disconnection is greatly reduced, this is the extra thick hard fabric: such as ABS hard box, strong thickened seat belt, etc. Why must choose not to loosen the Bonded thread!

Anti-aging performance test:
1. Take 3 sections of Bonded thread sample longer than 500mm, each circle into a small circle. After placing in the high and low temperature test chamber, perform a cycle: from normal temperature 23 °C ± 2 °C to 80 °C ± 2 °C, keep warm for 2 hours; cool down to 23 °C ± 2 °C for 2 hours; then cool down to -30 °C ± 2 ° C, kept for 2 hours; finally warmed to normal temperature 23 ° C ± 2 ° C, according to this cycle 10 times. The heating rate is approximately 1 K/min.
2. After completion, place the Bonded thread test sample in an incubator at 80 °C ± 2 °C for 7 days.
3. After the above two steps are completed, visually observe that the surface of Bonded thread should be free from whitening, embrittlement and powder cracking, and then carry out the tensile test of single Bondi sewing thread, 210#≥64N; 135#≥48N;90#≥43N To be qualified.
