Polyester yarns are fundamental to the performance and longevity of a wide range of industrial products. From hose reinforcement to binder yarns for fiber optic cables, tire cords, and industrial fabrics, the success of these applications hinges on achieving the right balance of mechanical properties. Among these critical properties, break strength, elongation, and shrinkage play pivotal roles. Each property serves a distinct purpose, and optimizing one can have a cascading effect on the others.

The recent news of Alfa Group's decision to close its filament polyester production plant in Mexico has sent shockwaves throughout the industry. Companies that once relied on Akra's products are now faced with the daunting task of finding suitable alternatives. While many high tenacity polyester fibers can be readily replaced, the Akra Type 161 presents a unique challenge due to its distinct physical properties.

When sewing, is your needle heating up and causing damage to your thread or material, compromising the strength of your seams? 

Synthetic textile yarns are used in low to medium pressure hose applications up to 300 psi as reinforcement. Circular Knitting and Spiral Wrapping are often used to integrate the reinforcing yarn into the garden hose, air hose, agricultural hose, industrial hose, automotive hose, etc. This article discusses these two methods and some tips that can improve processing for hose manufacturers using cone wound yarn for hose reinforcement.  

In today’s industrial textile manufacturing processes, spin finish plays an important role in the overall performance of Polyester Continuous Filament (CF) fibers and yarns. Nylon and polyester fiber yarn production lines commonly use additive finishes, and the market for polyester filaments is growing rapidly due to the sometimes-high cost and limited availability of nylon and the use of polyester as a cheaper more available substitution many applications. 

Your Class 7 Style sewing machine is an asset to your operations; one that needs careful maintenance to keep it in proper working order.
