SPH fiber is a new type of elastic fiber in the market in recent years. It is made of polyester compounds with different thermodynamic properties, PTT and pet, through parallel composite spinning, and then processed by relaxation heat treatment to form a crimped fiber with three-dimensional structure similar to sheep capillary and dense. Its tensile resilience is close to that of spandex, and its elastic durability is better than that of spandex.

SPH fabric also has the characteristics of easy curling and easy dyeing. SPH fiber can be used for shirts and skirts in summer, trousers and skirts in spring and autumn.

Compared with ordinary polyester fabric, SPH fabric is soft, fluffy, elastic and easy to deform in tension. After tensile deformation, SPH fabric has good tensile recovery performance and is prone to shear deformation, but the shear recovery is almost the same as that of ordinary polyester fabric. The surface smoothness of SPH fabric is equivalent to that of ordinary polyester fabric.
