Introduce high-performance Poly Core Spun bobbin sewing thread

To meet the growing demand of global clothing and industrial textile manufacturers for high-strength and highly wear-resistant sewing solutions, Ningbo Johnson Textile Co., Ltd has officially launched its high-performance Poly Core Spun (polyester core-spun sewing thread) series of products. With its unique structural design and outstanding technical parameters, these products aim to significantly enhance the sewing quality in areas such as denim clothing, workwear, outdoor equipment, and leather products.

Core Technology: High-strength Polyester Core + High-quality Outer Fibers

The Poly Core Spun sewing thread adopts a dual-component composite structure: The high-strength low-extensibility polyester filament is used as the core (accounting for approximately 60% of the total weight of the thread body), and is precisely wrapped with polyester short fibers or cotton fibers on the outer layer. This "core + skin" structure gives this product significant advantages over traditional short-fiber sewing threads:

Strength significantly enhanced: Under the same specifications, the strength of Poly Core Spun thread is 40% - 50% higher than that of 100% polyester filament thread, ensuring that it is less likely to break during high-tension sewing and stressed stitching.

Excellent wear resistance: The polyester filament core offers outstanding resistance to wear, particularly suitable for clothing parts such as jeans and workwear that need to withstand frequent friction.

Anti-fracture and anti-wrinkling: The higher tensile modulus ensures a more stable formation of the thread, effectively reducing the phenomenon of seam puckering, and lowering the risk of thread breakage caused by fabric shrinkage after washing.

Fine sewing performance: With the use of high-strength core wires, manufacturers can employ finer sewing thread specifications to achieve the same level of strength, thereby obtaining a smoother and more aesthetically pleasing sewing line appearance while reducing damage to the needle holes.
