industrial silk pet resin for sale

It can be used for the production of industrial yarn, monofilament, and biofilament.
Here we want to explain more about the application in composite elastic fibers, which are characterized by a side-by-side structure. In order to produce this fiber, we can blend low-viscosity PET (0.47-0.65 dl/g) with high-viscosity PET (0.82-1.05 dl/g). And then adjust the temperature of the spinning components. The resulting composite fibers have good elasticity, strength, and chemical stability. It can improve the elasticity and hand feel of fabrics.
composite elastic fibers made from this method have a more competitive price than Spandex.
